“Did the phased install myself over two years following the Year 1/3/5 plan. Looks exactly like the render. Best $13 I've spent on anything house-related.”
David R.
· Native prairie conversion
“I sent the PDF to three landscapers for bids. All three said it was the clearest project brief they'd ever gotten from a homeowner. Got quotes back within 24 hours.”
Marcus T.
· Pool area landscaping
“Small yard — 900 square feet — and a tricky slope. The design made it feel intentional instead of awkward. My neighbors keep asking who my landscape architect was.”
Jessica W.
· Urban townhouse yard
“I'm in zone 5b in Minnesota. Every plant it recommended actually survives our winters. I expected generic results — I got a hyper-local design that knew my soil and frost dates.”
Kevin A.
Minneapolis, MN · Cold-climate backyard redesign
“Needed privacy from the neighbors — didn't want a 6-foot fence ruining the yard. Yardcast designed a layered living screen with Green Giants, Skip Laurel, and ornamental grasses. Full privacy in year two. Gorgeous year-round.”

Try Yardcast Free →A 10×12 ft three-wall structure open to the pool — the most popular pool house form. Provides shade, a place to sit, and a surface for a mini-fridge or bar cart. Cedar or pressure-treated lumber frame with a simple shed roof. No plumbing required.
Pro tip: Orient the open wall to face north so the shaded interior stays cool even on hot summer days.
Steel frame with fabric canopy and curtain panels on tracks. Curtains pull back during swimming, close for changing privacy and afternoon shade. Outdoor-grade Sunbrella fabric resists mold and UV for 10+ years.
Pro tip: Use weighted curtain hems (add small weights to the bottom seam) to prevent billowing in breeze.
6×12 ft pergola with two posts alongside the pool + a 14×14 ft shade sail overhead. The sail catches wind and provides shifting shade. More architectural than an umbrella; less expensive than a solid-roof structure.
Pro tip: Shade sail fabric blocks 90–98% of UV — cheaper than building but requires shade sail replacement every 5–8 years.
Bamboo pole frame with a palm thatch or synthetic thatch roof — instant tropical resort look. Synthetic thatch is fire-rated and lasts 20+ years vs natural thatch's 5–8 years. Popular in Florida and Hawaii pool designs.
Pro tip: Synthetic thatch (Endureed or Permathatching) looks authentic but is fire-rated — required by most local codes.
Powder-coated steel frame with a polycarbonate or metal roof. Ultra-modern, low-maintenance, and weather-resistant. Pairs with a concrete pool deck for a contemporary look. Available as prefab kits from outdoor living companies.
Pro tip: White or light gray powder coat stays cooler in summer sun vs dark colors — 15–20°F difference in surface temperature.
A 6×8 ft structure with a toilet, small sink, and changing area. Eliminates wet swimsuits dripping through the house — the most common pool house complaint solved. Requires plumbing (water and sewer connection). The highest-ROI pool house addition.
Pro tip: Run the plumbing line before you pour the pool deck — retrofitting under concrete is expensive and disruptive.
A 10×12 ft pool bath with full toilet, vanity, shower, and an attached outdoor shower station on an exterior wall. Outdoor shower rinses off chlorine/sunscreen before the indoor shower — keeping pool chemicals out of the home's septic or municipal system.
Pro tip: Outdoor shower floors should slope at least 1/8 inch per foot to drain — flat floors pool water and create algae growth.
Two separate changing rooms flanking a central covered area — a symmetrical design often used in luxury pools. Each 5×6 ft room has a bench, hooks, mirror, and outdoor shower. No toilet required for building permits in many jurisdictions.
Pro tip: Adding an outdoor shower to each changing room side eliminates the need for a full plumbing permit in many counties — check local codes.
Convert a section of an existing garage, shed, or basement walkout into a pool bath. The most budget-friendly option — you're using an existing structure rather than building new. Often just requires adding a half-bath plumbing rough-in.
Pro tip: A basement walkout to the pool area is the holy grail — add a door, a half-bath, and you have a pool house for under $10K in many cases.
A freestanding cedar shower station (no enclosure walls needed) — posts + overhead shower head + bench + hooks. Minimalist, quick to build DIY, and requires only a single water line connection. No drain needed if you use a gravel drainage pit.
Pro tip: Use a pressure-treated or cedar base with a gravel drainage area — the water disperses naturally and eliminates the need for a formal drain.
A bar counter built into the pool edge with submerged bar stools — swimmers sit in the water at bar height. The most resort-like pool feature available. Requires a pool bench at the right depth (typically 3 ft water depth for bar stools).
Pro tip: Bar top height should be 6–8 inches above water level — test with a temporary setup before building permanent concrete.
An 8–12 ft covered bar counter adjacent to the pool with a built-in outdoor refrigerator, sink, and bar storage. The outdoor fridge eliminates 20+ trips to the house for drinks during a pool party. Cedar or teak countertop is most durable for outdoor use.
Pro tip: Size the refrigerator for the party load: a 4.5 cu ft mini fridge works for a family; a 15 cu ft outdoor fridge handles pool parties of 20+.
A 16×20 ft open-air pavilion housing a full outdoor kitchen — grill, side burner, sink, prep counter, under-counter fridge. The entertainment hub of the backyard. Poured concrete or travertine floor, wood beam ceiling with fans.
Pro tip: Add a TV in the pavilion for the best ROI — homeowners who add TV to their pool pavilion use it 3× more during summer than those without.
A thatched-roof tiki bar (8–10 ft bar counter) with 4–6 stools plus a shaded lounge seating area. Tropical drinks, string lights, and a bluetooth sound system. One of the most popular pool entertainment setups for entertaining-focused families.
Pro tip: Use marine-grade Bluetooth speakers — regular outdoor speakers rust and fail after one season in a pool environment.
A built-in outdoor bar cart parking station — a designated countertop and storage area that keeps bar carts organized and at the ready. Much simpler than a full bar build; great for pools where budget is a constraint. Add a mini fridge niche for $500.
Pro tip: Use commercial-grade bar cart bases (chrome or powder-coated steel) — residential indoor carts rust within two seasons in pool environments.
A 300–400 sq ft pool house with a bed, kitchenette, full bath, and sitting area. Doubles as a guest suite and pool changing room. Often the most cost-effective way to add a guest bedroom to a property without expanding the main house.
Pro tip: Check local zoning before building — many municipalities restrict sleeping quarters in accessory structures (ADU rules apply).
A permitted accessory dwelling unit (ADU) beside the pool — a fully independent living unit with kitchen, bath, bedroom, and laundry. Can be rented short-term (Airbnb) for income or used as a multigenerational suite. Most states have loosened ADU restrictions significantly since 2023.
Pro tip: ADU pool houses add significant appraised value to a property — often $100K+ in markets with high rental demand. Get a permit and do it right.
A 200–300 sq ft pool house with a home office zone (desk, wifi, AC) plus a bathroom. Work from the pool house during the day; guests sleep in it overnight. The dual-purpose nature makes financing the build much easier to justify.
Pro tip: Sound insulation between the office and living area is worth adding — pool parties and work calls don't mix without it.
A 20×30 ft open pavilion with a substantial roof (metal or cedar shingles), exposed beams, ceiling fans, pendant lighting, and a concrete or pavers floor. Not a closed structure — fully open air. Permits are simpler for open pavilions vs enclosed structures in most jurisdictions.
Pro tip: An open pavilion avoids the building permit headaches of enclosed spaces while adding nearly identical utility value for outdoor entertaining.
Convert an existing carriage house or barn adjacent to a pool into a full pool house. Historic properties often have underutilized outbuildings that can become stunning pool houses with character impossible to replicate in new construction.
Pro tip: Carriage house conversions get historic tax credits in some states — check with your accountant before starting the project.
Stucco walls, terracotta tile roof, arched windows, and a wrought iron chandelier. White plaster walls with an earthy red tile roof. Matching terracotta pool coping and Mediterranean plantings (lavender, rosemary, olive trees). A cohesive design that makes the pool feel like a Tuscan villa.
Pro tip: Use a single style palette from the house to the pool house — mismatched styles (Colonial house, tropical pool house) reduce property coherence and resale value.
Flat roof, floor-to-ceiling glass doors, concrete or steel exterior, and a monochromatic palette (white, gray, black). Zero ornamentation. Designed to make the pool house 'disappear' visually and let the pool be the star.
Pro tip: Concrete block construction for pool houses in high-humidity climates outlasts wood frame by 20–30 years — worth the 15% premium.
Board and batten exterior, metal standing seam roof, shiplap interior, and rustic wood accents. A white farmhouse pool house with black metal hardware has become the defining look for 2024–2026 pool design. Pairs with a simple rectangle pool and weathered wood deck.
Pro tip: Board-and-batten siding with 1×4 battens over 3/4-inch sheathing can be DIY-applied — saves $5,000–$15,000 in labor.
Thatch or palm-leaf roof, bamboo accents, tropical plants (bird of paradise, banana, palm), and bright colors. Designed to feel like a 5-star resort pool. Tiki torches, thatched bar, and lush tropical planting complete the experience.
Pro tip: Synthetic thatch from Endureed or Cape Reed is fire-rated and lasts 20+ years vs natural palm thatch at 3–5 years.
Exposed rafter tails, tapered columns on stone or brick piers, generous overhangs, and a low-pitched gable roof. Natural wood stain, stone accents, and arts-and-crafts hardware. Pairs beautifully with older Craftsman and Colonial homes.
Pro tip: Match the pool house column piers to the main house's porch piers material (brick, stone, or stucco) for design coherence.
Prefabricated pool cabana kits from Costco, Home Depot, or specialty manufacturers. Delivered on a flatbed and assembled in 1–2 weekends. 10×14 ft kits with a solid roof, one open wall, and wood frame. No architectural plans required in most jurisdictions.
Pro tip: Add a concrete pad before delivery — a 4-inch slab with a drain hole makes the kit dramatically more functional and durable.
Take a standard 12×16 storage shed kit and convert it: add a barn door or Dutch door facing the pool, paint white or grey, add a window, hang a mirror, and add a bench + hooks inside. A $1,500 shed becomes a $10,000-looking pool house with $2,000 in upgrades.
Pro tip: The Dutch door (split top/bottom door) is the #1 upgrade for a shed-turned-cabana — it opens the top for light and ventilation while keeping the bottom closed for privacy.
A 12×14 ft pergola kit from a big box store + outdoor curtain panels on wire cables. Curtains provide changing privacy and shade. Pergola kit takes 1 weekend to install. Add string lights overhead and a small outdoor rug for a complete pool retreat.
Pro tip: Attach the curtain wire to turnbuckles — allows you to re-tension curtains after stretching from sun and rain exposure.
A 20-ft shipping container converted into a pool house: cut openings for windows and a sliding glass door, spray-foam insulate, drywall, add a mini split AC, and paint. Industrial-cool aesthetic, extremely durable. Full bath addition requires plumbing.
Pro tip: Buy a 'one trip' container (used once from Asia) — they're $3,000–$4,000 and in pristine condition vs older containers with rust issues.
Two large offset cantilever umbrellas (9 or 11 ft each) with a teak or poly-lumber poolside daybed below. Not a structure per se, but provides shade, style, and a comfortable gathering area around the pool at minimal cost.
Pro tip: Cantilever umbrellas need 50–100 lb bases — lighter bases tip in wind. Fill the base with sand to maximize weight.
Place the pool house on the west side of the pool — it casts shade over the pool in the afternoon when the sun is most intense and the pool is most used. A west-side position means swimmers get afternoon shade automatically.
Pro tip: Test shadow patterns by placing a stick at the proposed location at 3 PM on a summer day — that shadow shows where shade will fall from a 10-ft structure.
Cabana (open air, no bath): 80–120 sq ft. Changing room + half bath: 100–150 sq ft. Full bath + bar: 150–200 sq ft. Guest suite: 300–500 sq ft. Oversizing adds cost; undersizing the changing room is the most common regret.
Pro tip: The changing room mistake: 6×6 ft feels fine until you have guests — size to 8×8 ft minimum if you'll ever have a pool party.
Run plumbing conduit and electrical conduit under the pool deck before pouring concrete — retrofitting under a poured deck costs $5,000–$15,000. Even if you don't install plumbing now, run the conduit for future use.
Pro tip: Ask your pool contractor to stub out a plumbing rough-in near the pool house location during pool construction — it's a $500 add-on vs a $8,000 retrofit later.
The single biggest design mistake is building a pool house in a different style than the main house. A stucco Mediterranean house with a modern black-steel pool house looks incoherent. Match roofline pitch, siding material, trim color, and architectural details.
Pro tip: Take a photo of your house and send it to your builder before drawing plans — matching the style is worth paying a designer $500–$1,000 for 2 hours of guidance.
Most pool houses larger than 120 sq ft require a building permit, and any structure with plumbing requires a plumbing permit. Unpermitted pool houses are increasingly flagged during home sales. The permit process ensures the structure is safely built and protects your home's value.
Pro tip: Permit costs are typically 1–3% of the project cost — money well spent to avoid a $10,000+ demolition order during a home sale.
| Type | Cost Range | Size | Bathroom | Permits | Best For |
|---|---|---|---|---|---|
| Pool Umbrella / Shade Sail | $300–$3,000 | N/A | No | Usually no | Renters, smallest budgets |
| Open Cabana (3-wall) | $3,000–$12,000 | 80–120 sq ft | No | Sometimes | Shade, casual seating |
| Changing Room Only | $5,000–$15,000 | 40–80 sq ft | Outdoor shower | Usually yes | Eliminating wet feet in house |
| Cabana + Half Bath | $15,000–$40,000 | 100–180 sq ft | Half bath | Yes | Most popular choice |
| Full Bath + Bar | $30,000–$80,000 | 200–350 sq ft | Full bath | Yes | Entertaining families |
| Full Guest Suite | $80,000–$250,000+ | 300–600 sq ft | Full bath | Yes (ADU) | Luxury, rental income, guests |
Pool house costs range from $3,000 for a basic open cabana to $250,000+ for a full guest suite. The most popular option — a pool cabana with a half-bath — costs $20,000–$50,000 installed. Key cost drivers: plumbing ($8,000–$20,000 for a bathroom), size (expect $150–$300/sq ft for a finished structure), and site access. A freestanding structure in an accessible location costs less than one wedged between existing landscaping.
Yes — significantly. A basic pool cabana adds $5,000–$15,000 in appraised value. A full bath pool house adds $20,000–$40,000. A permitted guest suite ADU can add $80,000–$150,000 in some markets. The ROI varies by market: in luxury and high-income areas, pool houses are expected and priced into the property. In mid-tier markets, the ROI is typically 50–70% of construction cost.
Usually yes, especially if it's over 120 sq ft, has plumbing, or has electrical service. Rules vary significantly by municipality — some allow 200 sq ft accessory structures without permits; others require permits for any structure over 50 sq ft. Any structure with plumbing always requires a plumbing permit. Unpermitted pool houses create problems during home sales. Always check local zoning codes before building.
Must-haves: shade (roof), storage (for pool toys and chemicals), and a place to sit. Nice to have: a bathroom or outdoor shower (eliminates wet trips through the house), a refrigerator or bar (eliminates trips to the kitchen). Premium: full bath, outdoor kitchen, changing rooms. The bathroom is the highest-ROI addition — many homeowners who skip it regret it within the first pool season.
Setback requirements vary by municipality, but typical requirements are: 10 ft from the pool edge, 5–10 ft from property lines, and outside any drainage easements. Some municipalities restrict accessory structures to specific zones of a property (rear yard only). Check your local zoning code and HOA rules before designing. A surveyor can confirm exact property lines — critical before placing a permanent structure.
A pool house typically refers to a fully enclosed structure with plumbing, electricity, and amenities like a bathroom, kitchen, or sleeping quarters. A cabana is generally a simpler, open-air or 3-wall structure focused on shade and changing. In practice, the terms are used interchangeably. The functional distinction: a pool house can stand alone as living space; a cabana depends on the main house for utilities.
