Yes, you can put a hot tub under a pergola, and thousands of owners already do. A pergola shades the water in summer, blocks light drizzle, and gives you privacy. Size it so the tub has at least 18 inches of clearance on every side and the interior clear height is 7 feet or more, then measure with the cover installed.
That last sentence is where most installs go wrong. Buyers measure the empty tub, order a structure to fit, and discover that the cover on top of the water plus the equipment bay on one side eats every inch of the gap they had left. Owners posting on r/hottub repeat the same planning error in thread after thread.
This roundup covers eight pergolas built for a tub, a swimspa, or a spa deck, across cedar kits, aluminum louvered structures, and metal designs with curtains. We ranked them on clearance fit for a hot tub footprint, shade control, published wind ratings, drainage routing, maintenance burden, and warranty coverage. We did not rank them on appearance, because taste is yours to make.
One more note before we start. Once the structure is up, the space tends to become the spot you actually host from. Our refreshing summer dinner ideas are the usual follow-up for anyone who puts a grill on the deck next to the spa.

1. Backyard Discovery Beaumont 16 x 12 Cedar Pergola Kit – Best Overall for Hot Tubs
Backyard Discovery Beaumont 16′ x 12′ Traditional Cedar Wood Pergola Kit with Trellis Roof, All-Season Durability, High-Wind Rating, PowerPort, Shade for Outdoor Patio, Deck, Garden, and Entertaining
100% cedar
192 sq ft coverage
Tested to 100 mph winds
PowerPort with 3 outlets and 3 USB ports
Pros
- Real 100% cedar with a pre-stained finish
- Roomy 192 sq ft of shade coverage
- Stays put in severe wind when properly anchored
- Pre-drilled parts and BILT app instructions
Cons
- Assembly is a multi-day project needing at least three people
- Lumber arrives untreated and must be sealed before assembly
- Some field-drilled purlin holes do not line up
This is the structure we would put over a 7 or 8 person tub without hesitating. At 192 square feet it swallows a large square spa and still leaves walking room on three sides, which is the difference between a cover you can actually lift and one you have to fight.
The 100 mph wind rating is the highest published figure in this group, and it is the number that matters most when a structure sits next to an open yard with a hot tub throwing moisture into the air. Owners repeatedly say the kit stays where it is once the galvanized steel anchor plates are actually used, and that the posts are not solid 6×6 timbers. Know that before you buy.
The PowerPort is a genuine convenience for a tub area. Three outlets and three USB ports on one post means your pump controller, phone, and towel warmer all have somewhere to go, though the power source itself is not included, so budget for a GFCI-protected circuit.
The honest drawback is assembly. Reviewers describe it as a multi-day project that needs at least three people for the standing sections, and the lumber ships untreated, meaning you are sealing wood before it goes up rather than after. The BILT app instructions are the reason most people finish it at all.
Who this pergola suits
It suits owners of large square tubs and swimspas who want real walk-around clearance and do not mind a weekend of building. If your deck is already framed and level, the anchor plates and resin feet handle ground moisture well.
It also suits anyone who wants to add features later. Owners bolt on extra trellises, wiring, and lighting without fighting the structure, which is something thinner metal kits make hard.
Who should skip it
Skip it if you need the structure up in an afternoon or you are not prepared to seal the lumber before assembly. Field-drilled purlin holes that do not line up with the frames are a recurring complaint, and shipping damage on a 546-pound kit is a real possibility.
Also skip it if you want adjustable shade. An open trellis roof gives you dappled light and privacy, not the fine sun-to-shade control a louvered structure gives you.
2. PURPLE LEAF 11 x 15 Louvered Pergola 94AS – Best for Shade Control Over a Hot Tub
PURPLE LEAF Louvered Pergola 11′ x 15′ 94AS with Two Adjustable Roof Gray
Aluminum frame
11 x 15 ft footprint
Two independent 0-90 degree louver roofs
72 mph wind rating
Pros
- Two independent louver roofs balance sun
- shade and airflow
- All-aluminum louvers avoid the rust-jam problem
- Integrated drainage routes rainwater down the columns
- Reinforced frame with 5.12 inch wide beams
- Open and tall feel suits gathering space
Cons
- Large footprint needs a substantial pad or deck
- Cranking the louvers means reaching poles from the ground
- Shade screens and LED strips are sold separately
If your priority is controlling the sun hour by hour rather than blocking it entirely, this is the structure. The 94AS is the tallest design in the PURPLE LEAF line, at just over 94 inches, with an open, grand feel that suits a tub plus seating.
Two independently adjustable louvered roofs are the real feature. One section can be closed against the afternoon sun while the other stays open, which on a tub matters because the water reflects light straight up at whoever is soaking. The 0 to 90 degree range covers everything from full shade to full open sky.
Drainage is routed through the four columns, so water leaves through the posts rather than dripping onto the deck around your spa. Owners coming from fabric canopies specifically look for this, and the people on r/hottub who ask about louvered roofs leaking into the water point to routing as the number one thing to check in a spec sheet.
Everything is aluminum and powder-coated, which removes the rust-jam failures that cheaper shutter systems develop. The frame is reported as 1.8 times heavier than standard models, and the wind rating is 72 mph.
Who this pergola suits
It suits owners who soak year-round and want to dial shade rather than accept a fixed roof. A 511-pound aluminum structure needs a properly built base, and a poured slab is the simplest answer for the water load.
It also suits anyone adding accessories later, since shutter walls, shade screens, integrated LED strips, and outdoor string lights are all designed to fit this line.
Who should skip it
Skip it if your patio is small. At 11 by 15 feet, the footprint demands a substantial pad, and cranking the louvers means reaching the poles from the ground rather than from a remote.
Skip it if you want curtains in the box. Nothing soft comes with it, so evening privacy means a separate purchase.
3. MIRADOR 80S 10 x 12 Louvered Pergola – Best for Small Patios and Compact Spas
MIRADOR 80S 10’x12′ Louvered Pergola with 12FT Shade Screen for Outdoor Deck Lawn Garden Backyard Patio Porch，Charcoal
10 x 12 ft footprint
Adjustable louvered roof
12 ft shade screen included
Pros
- Includes a 12 ft shade screen in the box
- Adjustable louvered roof dials shade and airflow
- Waterproof construction with UV protection
- Charcoal finish suits modern gardens and decks
Cons
- Listed dimensions conflict with the 10 x 12 footprint
- Tight for walk-around clearance beside a tub
- Shade screen is a separate add-on in other size variants
Most compact tubs need a structure bigger than the tub, and that is where this one runs into trouble. A 10 by 12 foot footprint over a small round spa is workable. Over a 7 person square tub, the walk-around space gets tight fast.
What you get for that footprint is unusually complete. The 12 foot shade screen comes in the box, which matters more than it sounds, since screens are frequently an add-on in other sizes. The louvered roof lets you trade shade for airflow as the afternoon heats up.
Construction is alloy steel and aluminum in charcoal, rated waterproof with UV protection, so it handles a wet tub environment without warping the way untreated wood can. Owners like the modern styling and the way it disappears against a dark deck.
One thing to settle before you order: the published dimension data is inconsistent with the 10 by 12 footprint. Confirm the clear height and post positions with the manufacturer before you pour anything, because a mismatch here is expensive to fix later.
Who this pergola suits
It suits owners of a 2 to 4 person tub in a side yard or a tight urban patio who want adjustable shade without a second purchase. The included screen means you can use it at dusk straight out of the box.
It also suits anyone who prefers a modern charcoal look to a rustic wood one and does not want to stain anything every other year.
Who should skip it
Skip it for a large square tub. Ten feet of width leaves little perimeter clearance, and clearance is what lets you lift a cover and reach the pumps and heater. If your tub is 8 by 8 feet, you need a bigger roof.
Skip it if you plan to build a large slab. The 10 by 12 footprint offers little margin, and the dimension data is not consistent enough to trust without confirming first.
4. BlueWish 12 x 16 Cedar Pergola with Slatted Trellis Roof – Budget Pick
BlueWish 12’x16’ Patio Pergola, Cedar Wood Pergola with Unparalleled Slatted Roof Trellis, Outdoor Pergolas Backyard Gazebo with Solid Structure for Deck Grill Party Garden
Solid cedar
192.1 sq ft footprint
Rated against 80 mph winds
Interior clear height 86.6 inches
Pros
- Wide 12 x 16 footprint for the money
- Double beam slatted roof resists wind and vibration
- Cedar is naturally rot and moisture resistant
- Pre-drilled posts shorten install time
- Open slats keep the view bright
Cons
- Needs your own water-based stain for longevity
- Not suitable for installation on pavers or stone
- 192 sq ft of cover needs a substantial base
For the coverage you get per dollar, nothing else here competes. You are buying 192.1 square feet of solid cedar with a double beam slatted trellis roof, and the overall footprint is 192.1 inches long by 137.8 inches wide.
The double beam roof is more than styling. It adds rigidity against the wind and the vibration a hot tub creates when the pumps cycle, and the published wind rating is 80 mph, the second highest figure in this roundup after the two 100 mph cedar kits.
Interior clear height is 86.6 inches, which clears our 7 foot minimum with a little room to spare. Posts measure 5.51 inches square and arrive pre-drilled, and owners consistently report a shorter install because of it.
One restriction matters more than it looks. The manufacturer does not recommend this kit on paver or stone installations, since stakes and pavers do not work together well. Cement, concrete, and wooden floors are all listed as fine.
Who this pergola suits
It suits owners of a 6 to 7 person tub on a concrete pad who want genuine coverage without spending metal-pergola money. The open slats block overhead sun while keeping the view and the daylight.
It suits anyone who likes the look of climbing plants, since the slatted trellis roof is built for vines like ivy and morning glory.
Who should skip it
Skip it if you want adjustable shade or weather shelter. Open slats are shade, not protection, and this is not a structure you sit under in a storm.
Skip it if your base is pavers or stone, or if you are not willing to apply a water-based stain after assembly. Cedar handles moisture well on its own, but a stain job is what keeps it that way.
5. MUPATER 12 x 16 All Cedar Pergola Kit – Best Value
MUPATER 12×16 FT All Cedar Wood Wooden Pergola, Pergola Kit with Stakes, Quality Wood Supported Structure, Snow and Wind Supported, Outdoor Garden Shelter with Cedar Framed for Backyard, Deck, Lawn
All cedar
12 x 16 ft kit
321.9 pounds
Interior entrance height 86.6 inches
Pros
- Full 12 x 16 cedar kit at a low entry cost
- Clear written instructions plus an assembly video
- Metal ground piles give stable anchoring
- Fluted roof suits climbing vines
- Legs can be adapted for deck mounting
Cons
- Wood dents and scratches easily during handling
- Posts arrive with shipping gouges
- Extra stain or sealant is required
This is the kit for anyone who wants a full 12 by 16 cedar structure and a realistic weekend. Reviewers put the build at roughly three to four hours with two people, which is faster than anything else in this roundup.
The cedar is described as rot-resistant and suitable for humid climates, which matters beside a tub where the air stays wet. At 321.9 pounds it is also the lightest kit here, which is a real advantage when you are carrying boards from the driveway to a deck.
Anchoring is handled by metal ground piles, and the legs can be adapted if you are mounting on a deck rather than in soil. Additional anchor bolts are used when the base is concrete. Maximum entrance height is 86.6 inches, so standing up in the tub works but is not generous.
The fluted, battened roof gives partial shade, and owners like the rustic look it puts on a garden. The roof beams are also rated to take a lightweight hammock, swing, or ceiling fan.
Who this pergola suits
It suits first-time builders and anyone who wants a large footprint without a multi-day project. The written instructions and the assembly video are the most reassuring part of the package for a kit this size.
It suits owners in humid or coastal areas who want the natural look of cedar and are comfortable with a basic stain routine each year or two.
Who should skip it
Skip it if you are fussy about finish. Dents, scratches, and gouged posts are the most-reported complaints, and they are cosmetic but permanent in cedar.
Skip it if you need a warranty-backed structure or a published wind rating. This kit is described as snow and wind supported without a specific figure, so if you live somewhere with serious weather you are relying on the general construction rather than a test result.
6. Backyard Discovery Somerville 14 x 10 Walnut Cedar Pergola – Best for Traditional Yards
Backyard Discovery Somerville 14 x 10 Walnut All Cedar Pergola, Durable, Quality Supported Structure, Snow and Wind Supported, Rot Resistant, Electrical Outlet with USB, Deck, Garden, Patio
All cedar
Walnut finish
Tested to 100 mph winds
7 ft interior clear height
Removable PowerPort
Pros
- All cedar with natural rot and decay resistance
- Classic archway styling suits traditional yards
- Removable PowerPort moves between posts
- Resin feet and concrete anchors keep it off damp ground
Cons
- 14 x 10 is the smallest covered area in this group
- Interior headroom of 7 ft is the lowest here
- PowerPort needs a separate power source to function
Where the Beaumont is generous, the Somerville is compact, and that is the whole story. The base is 11 feet 11 inches by 7 feet 12 inches with an interior of 10 feet 11 inches by 7 feet, and the 4.3 average rating reflects people who loved the look and felt the space was small.
What you get is classic. A multilevel roof trellis with an archway design, all cedar, and a walnut tone that reads more traditional than rustic. The 100 mph wind rating matches the Beaumont for the highest published figure here.
The removable PowerPort is the detail owners mention most. Three outlets and three USB ports that unclamp and move to any post means you can position power near the tub door, then move it out of the way when the area is not in use.
Resin feet and concrete anchoring plates keep the posts off damp ground, which is the right call in a tub area where the ground stays wet for long stretches.
Who this pergola suits
It suits owners of a small round or 2 to 4 person tub in a traditional garden who want the archway look rather than a modern one. Pre-cut, pre-drilled, pre-stained parts make the build manageable.
It also suits anyone who wants built-in power they can relocate as their layout changes.
Who should skip it
Skip it for a large tub. Seven feet of interior depth and a 7 foot clear height leave a standing bather with very little room, and this is the smallest covered area in the group.
Skip it if you need shade you can adjust. The trellis roof is fixed, and the structure has no louvers to open or close.
7. FansaFurn 12 x 16 Pergola with Curtains and Adjustable Roof – Best for Privacy
12′ x 16′ Pergola with Curtain & Adjustable Roof & Aluminum Frame for Patio
Aluminum frame
12 x 16 ft, 192 sq ft
Louvers block up to 99 percent UV
Curtains and mesh included
Pros
- Aluminum and metal frame resists rust/moisture and UV
- Curtains and breathable mesh netting ship in the box
- Hidden drainage channels in each column
- Rated 72 mph winds and 6 inches of snow
- Concealed fasteners pair well with string lights
Cons
- Arrives in 9 separate boxes at different times
- Expansion bolt anchoring needs a hard surface
- Curtains and netting must be tied off in high wind
Privacy is the reason to pick this one. The curtains and breathable mesh netting are included, and the netting keeps insects out while still moving air, which means you can sit in the structure on a summer evening without feeling sealed in.
The louvers block up to 99 percent of UV rays and adjust from 0 to 90 degrees, so the same roof gives you hard shade at noon and open sky in the evening. At 192 square feet it covers a large tub with room for people on the edge.
The canopy is rated for up to 6 inches of snow with a load capacity of 55 pounds per square meter, and the structure is rated for 72 mph winds. Drainage runs through hidden channels inside each column, so the deck under the roof stays dry rather than collecting runoff.
Two practical notes. The package arrives in nine separate boxes that may show up on different days, so plan for a delivery window rather than a single drop. And the frame is anchored with expansion bolts, which means a hard surface is required.
Who this pergola suits
It suits owners with close neighbors, a corner lot, or a tub near a street who want evening use without being on display. The curtains and netting combination is the closest thing in this roundup to a soft-sided room.
It also suits cold-climate owners. The snow capacity figure is the only one published in this group, and 6 inches of accumulation is meaningful in places that get real winters. Our hot mulled cider ideas are what we would make after a January soak under it.
Who should skip it
Skip it if you are not prepared to tie off or remove the fabric in high wind. Loose curtains on a louvered frame are the one thing here that can catch badly.
Skip it if you are on soil. Expansion bolt anchoring needs concrete, cement, or another hard surface, which means planning the base before the structure arrives.
8. Modern Shade 12 x 12 Louvered Pergola with USB Power Strip – Best for Built-In Power
Modern Shade Pergola 12’x12′ with USB Power Strip & Net and Curtain, Black
Metal frame
12 x 12 ft, 144 sq ft
83 mph wind rating
Built-in outlet and USB ports
Pros
- Highest average rating in this group with 90 percent of reviews at 5 stars
- Built-in standard outlet and USB ports
- Concealed gutters with leaf-proof guards
- 83 mph wind rating
- Curtains and privacy nets slide independently on a double track
Cons
- Only 20 reviews
- so long-term durability is unproven
- Expansion bolt anchoring needs a hard surface
- 12 x 12 is snug for a tub with clearance on all sides
This has the best rating of the eight and the smallest review base, which is worth saying plainly. Twenty reviews and no ratings below 4 stars tells you current owners are happy. It does not tell you how the frame looks after eight winters.
The built-in standard electrical outlet plus USB ports is the standout feature, and beside a hot tub it is more than convenient. You are running a pump controller, a heater check, and lighting in an area where running extension cords across a wet deck is the wrong idea.
Drainage is the second thing to notice. Concealed integrated gutters with leaf-proof guards route water down the columns, and the leaf-proof guard matters in a tub area where you have trees overhead and standing water on the roof after every storm.
The wind rating is 83 mph, the highest among the metal structures here. Louvers run from 0 to 85 degrees on two crank handles, and the dual-track system lets curtains and privacy nets move independently rather than as one layer.
Who this pergola suits
It suits owners who want built-in power and who have a hard, anchorable surface already in place. The outlet and USB ports remove the extension cord problem entirely, and the leaf-proof gutters suit yards with trees. If you also cook out there, our best hot plates tested cover what works on a deck burner.
It suits anyone who wants curtains and netting that can be used separately, since the double-track canopy lets you close one layer and leave the other open.
Who should skip it
Skip it if you are buying on review count. Twenty reviews is thin, and the long-term record on a powder-coated frame in a salt-heavy coastal air is not something the current ratings can tell you.
Skip it for a large tub. A 12 by 12 footprint is snug once you allow 18 inches of clearance on each side, and the crank stopping at 85 degrees is a small but permanent limit on your shade range.
How Big Should a Pergola Be for a Hot Tub?
Plan on an interior clear height of 7 feet minimum, and give a standing bather 12 to 24 inches above that. A person standing in a tub is roughly 7 feet tall when the water lifts them, and a structure at exactly 7 feet of interior height is fine for sitting and uncomfortable the moment somebody stands up.
On the ground plan, allow at least 18 inches of clearance on every side, and more on the side where the cover comes off. Those numbers are the difference between a structure you can work around and one you resent. The most common mistake is measuring clearance without the tub cover in place, and it is the error r/hottub owners warn about more than any other.
A simple rule covers most residential tubs: add 3 feet to the tub’s longest dimension in each direction, then check that the result gives you a walkable path on all four sides. For an 8 by 8 foot tub, that lands on a 14 by 14 foot footprint, which is why the 12 by 16 kits in this roundup work and the 10 by 12 ones feel tight.
Measure twice, in a specific order. First, measure the tub with its cover fully on, because the cover arcs upward and outward. Second, measure the equipment bay, since pumps, the heater, and plumbing connections need a serviceable gap. Third, walk the perimeter and confirm you can lift a folded cover without hitting a beam.
Pergola vs Gazebo for a Hot Tub
A pergola over a hot tub gives you shade and airflow. A gazebo gives you shade and walls, which means more heat retention in winter and more moisture trapped in summer. Most buyers who regret the choice regret the enclosure, not the structure.
Open-slat roofs are cedar trellises. They cut overhead sun, keep the view bright, and cost the least, but they are not shelter from rain and they collect snow fast. Louvered aluminum roofs rotate between open and closed, shed water through the posts, and give the best year-round control of anything here. Fabric canopies are the softest and the least durable in wind. Hardtops shed weather properly and hold heat, and they need the most clearance underneath.
For a hot tub specifically, louvered or slatted wins over enclosed. The tub puts roughly 100 pounds of water vapor into the air per hour while it runs, and owners on r/hottub report damp decking and mildew specifically when a tub is boxed in. A roof that moves air solves more problems than a wall that keeps it out.
What to Look for When Buying a Pergola for a Hot Tub
Start with the load question, because it is the one most people get backwards. The pergola is not your structural problem. Water weighs about 62 pounds per cubic foot, so a filled 7 person tub approaches 5,000 pounds, and that entire load goes into the base, not the frame.
A typical residential deck is built for roughly 40 pounds per square foot of live load plus 15 pounds per square foot of dead load, which is why owners on poolspaforum.com report sagging after moving a tub onto an unengineered deck. A poured concrete slab is the simple answer, and forum consensus leans strongly toward slab or paver bases unless the deck has been engineered.
Beyond the base, these are the criteria that decide the outcome:
1. Interior clear height of 7 feet or more, with headroom above that for a standing bather.
2. Perimeter clearance of 18 inches minimum, more on the cover removal side.
3. A published wind rating. The structures in this roundup range from 72 mph to 100 mph, and the differences matter more in open yards than most listings admit.
4. Drainage routing through the posts rather than dripping onto the deck or into the tub water. This is the single most-searched question from louvered pergola owners.
5. Snow load capacity if you are in a region that gets winter precipitation. Only one structure here publishes a specific figure, at 6 inches of snow.
6. Service access for pumps, heater, and plumbing that stays usable after the structure is up.
7. Anchor type matched to your base, whether that is ground piles for soil or expansion bolts for concrete.
8. Material maintenance, honestly stated. Cedar needs sealing. Aluminum needs nothing but a rinse.
9. A warranty that names a length. The two Backyard Discovery kits here carry a 5-year limited warranty.
Permits, GFCI and Ventilation for a Pergola Over a Hot Tub
Any circuit serving a tub area needs GFCI protection, and a structure over a hot tub with outlets, lighting, or a powered cover is exactly where that rule gets tested. The two cedar kits with a PowerPort and the metal pergola with a built-in outlet and USB ports all need a GFCI-protected source, and none of them include the power source.
Check your local building department before you build. Permit triggers vary widely, and the threshold that matters most for you is usually footprint or height rather than the word pergola. Setback from the property line is a separate question, and it is the one that causes disputes with neighbors.
On ventilation, the practical answer is to leave the perimeter open. An 18 inch gap on all sides lets moist air escape, and a louvered or slatted roof lets warm air rise out. Fully enclosed structures over tubs are where the mildew reports come from, and they are why some owners deliberately choose a freestanding structure set beside the tub rather than a tight enclosure around it.
Finally, keep egress simple. A bather who has been in hot water can become lightheaded quickly, and a structure with fixed walls on three sides is a genuine safety problem, not just an aesthetic one. One open side is the minimum we would accept.
Frequently Asked Questions
Is it possible to put a hot tub under a pergola?
Yes. Thousands of owners run hot tubs under pergolas, both open-slat cedar kits and louvered aluminum structures. The requirements are an interior clear height of 7 feet or more, at least 18 inches of clearance on every side, and a base engineered to carry the water load independently of the structure.
How tall should a pergola be above a hot tub?
Plan on at least 7 feet of interior clear height so a seated bather fits, and add 12 to 24 inches above that so someone can stand up in the tub. Measure with the tub cover installed, because the cover arcs above the water and reduces the usable space you counted on.
Should a hot tub be under a gazebo or a pergola?
A pergola is usually the better choice. A slatted or louvered roof blocks sun while keeping air moving, which matters because a running tub releases substantial water vapor. A fully enclosed gazebo retains more heat in winter but traps moisture in summer, and owners report damp decking as a result.
Do pergolas over hot tubs get moldy?
The structure itself does not mold, but the deck and framing beneath a tight enclosure can. A running tub releases around 100 pounds of water vapor per hour, so keep at least 18 inches of open perimeter, use a louvered or slatted roof, and run the tub cover off during the day to let trapped moisture escape.
How much weight can a pergola hold?
The pergola is not your load problem. Water weighs about 62 pounds per cubic foot, so a filled 7 person tub approaches 5,000 pounds, and that weight sits entirely on the base. A typical residential deck handles roughly 40 pounds per square foot of live load, so a poured slab or engineered deck is what matters.
Is it cheaper to buy a pergola or build one?
A kit is cheaper in material cost and far cheaper in time. Building from scratch lets you size the structure exactly to your tub and choose any footprint, but it means sourcing lumber, designing the roof, and handling anchoring yourself. Kits ship pre-cut and pre-drilled, which is why most buyers choose them despite the higher total.
The Best Pergola for Your Hot Tub in 2026
The Backyard Discovery Beaumont is the best pergola for hot tubs we reviewed this year, and the reason is coverage plus evidence. 192 square feet, a 100 mph wind rating, cedar that owners actually like standing under, and more than a thousand reviews of the result. It is also the most work to build, so plan the weekend.
If you want shade you control rather than shade you accept, go with the PURPLE LEAF 94AS and its two independent louvered roofs. If your pad is small, the MIRADOR 80S is the honest answer, with the understanding that 10 feet of width is snug beside a large tub. For the most coverage you can get for the money, the BlueWish 12 by 16 cedar kit is hard to argue with.
Whichever one you choose, do the measuring before the ordering. Interior height of 7 feet, 18 inches on every side, cover installed, equipment bay accessible, base carrying the water. Get those four right and the structure is the easy part of the project.
