How to Build an Outdoor Shower Enclosure - Outdoor Cabinets

An outdoor shower enclosure is the perfect way to add a luxurious spa-like experience to your backyard. Having an outdoor shower allows you to rinse off after swimming, gardening, or just enjoying the outdoors without tracking dirt inside your home. Building your own outdoor shower enclosure may seem daunting, but with proper planning and materials, it can be an easy and rewarding weekend project.

Choose a Location

When deciding where to build your outdoor shower enclosure, there are a few factors to consider:

Convenience – Pick a spot near an existing exterior water line to avoid complicated plumbing. Locate it near the area you’ll use it most, like next to a pool or garden.
Privacy – Make sure the location allows for privacy from neighbors or other areas of your yard. Strategically place it out of direct sight lines.
Sunlight – Consider the sun’s path to maximize warmth but minimize hot afternoon sun beating down. A northern exposure often works well.
Aesthetics – Choose a location that fits in nicely with the style of your home and landscaping. Tuck it behind foliage or coordinate materials.
Drainage – Ensure proper grading and drainage so water doesn’t pool around the foundation. Plan for the slope to run water away from the shower floor.

Once you’ve selected the perfect spot, mark it off to visualize the size and shape of your outdoor shower enclosure.

Choose a Foundation

There are a few foundation options to support your outdoor shower structure:

Concrete slab – Poured concrete provides the most permanent and durable base. It involves forms, rebar, pouring, and finishing.
Gravel – Compacted gravel packed around the perimeter can suffice, especially for pre-fabricated stalls.
Pavers – Installing patio pavers or bricks will elevate the floor. Allow for drainage gaps between.
Wood platform – A simple wooden deck or platform can work, but ensure proper treatment and sealing. Add a waterproof mat on top.

For best results, choose a non-porous foundation that will resist shifting and deterioration from water exposure. Make sure it slopes slightly to shed water.

Choose Building Materials

There are many options when selecting building materials for your outdoor shower walls and structure:

Wood – Cedar and redwood are naturally rot-resistant woods ideal for outdoor showers. Waterproof and seal properly.
Tile – Ceramic, stone, or glass tile add a finished look and are waterproof. Use cement board as the substrate.
Concrete blocks – Stack concrete masonry units and mortar in place for an inexpensive sturdy wall.
Plastic – Panels made of PVC, acrylic, or fiberglass can create a waterproof enclosure. Look for textured finishes.
Metal – Aluminum, galvanized steel, and powder coated metals can withstand weather exposure. Choose rust-resistant.
Bamboo – Durable and sustainable bamboo sheets offer a natural look. Use marine varnish to seal.
Glass block – Translucent glass block panels let in light. Mortar in place for a custom look.

Choose building materials that complement your home’s aesthetics and fit your budget. Waterproofing treatment and proper sealing are essential.

Design the Enclosure Style

There are a few basic design styles to consider for your outdoor shower enclosure:

Stall – The simplest design with three walls and an open entrance. Offers fast construction but least privacy.
Partial enclosure – Two or three walls with a curtain across the entrance opening. Allows for airflow.
Full enclosure – Walls on all four sides with a door for entry. Provides most privacy but least ventilation.
Raised floor – Building a platform floor raises the shower floor for improved drainage and easier access.
Built-in bench – Incorporate a bench or corner seat for functionality and comfort. Tile, wood or fiberglass work.
ADA accessible – For wheelchair accessibility, plan for a wider entry, grab bars, bench and non-slip floor.
Open top – An open roof with partial walls allows rainfall rinses with a natural feel.

Choose an enclosure style that fits your space, functional needs and design aesthetic. Plan for drainage, privacy and visual appeal.

Choose Plumbing Parts

Selecting the right plumbing parts ensures your outdoor shower functions properly:

Shower head – Choose a durable brass shower head with adjustable mount bracket. Go for rainfall style if open top.
Faucet – Pick a single handle faucet or mixer valve suitable for outdoor use. Look for anti-scald protection.
Hose – Stainless steel braided hose resists kinks. Get one long enough to reach from the shower to faucet.
Drain – Install a 2-3” PVC drain pipe sloped downward from shower floor to area drainage. Include a removable grate cover.
Water lines – Run 1⁄2” size hot and cold PEX water lines underground from the home to the shower enclosure. Insulate hot line.
Shut off valves – Include separate shut off valves for hot and cold supply lines for easy maintenance.
Tempering valve – Adding a thermostatic mixing valve helps regulate water temp and prevent scalding.

Choose durable brass fixtures rated for outdoor use. Consult local codes for requirements. Consider adding insulation or heat trace for cold climates.

Build the Framework

The framework provides essential support for your outdoor shower walls and roof. Here are some tips for construction:

Set posts or studs into the ground or attach to your foundation. Pressure treated lumber is rot resistant.
Space framing members 16” on center for rigidity. Use 2×4 or 2×6 lumber depending on wall height and span.
Consider hurricane ties, brackets and head bolts for added structural stability in windy climates.
Frame walls to desired height and shape of enclosure. Mark openings for entryway(s).
Add double top plates and framed openings for windows, skylights or open roof as desired.
Erect additional posts to support roof ridge beam and rafters if adding an overhead roof.

Follow local codes for structural requirements. Check plumb and square as you build. Making the framework sturdy and level results in easier wall installation.

Add Exterior Wall Covering

Once the framework is complete, install your desired exterior wall covering:

For wood walls, attach cedar boards horizontally with galvanized finish nails. Maintain 1/8” gaps.
For PVC or other plastic panels, screw into framing using exterior screws with neoprene washers.
For concrete block, lay blocks level in mortar, checking plumb often. Scrub any mortar splatters promptly before dry.
For tile, apply cement backer board first, then thinset and tile using a waterproof membrane at seams.
For glass block, mortar panels into place. Use silicone caulk at corners. Add wood framing around edges.
Trim openings for doors and windows. Flash properly to prevent leaks.

Take careful measurements and use adhesive and mechanical fasteners as needed per the manufacturer’s instructions for your specific wall materials.

Add Roof and Door

Adding a roof and door completes your outdoor shower enclosure:

For a gable roof, attach asphalt shingles or metal roofing to roof rafters and sheathing.
For an open top, you may only need roof beams or a pergola to mount the shower head under.
Weatherproof the door by sealing the edges and adding flashing above.
Use a pre-hung exterior door or build a custom door from rot-resistant wood.
Add a latch or lockset for privacy. Install doorstops to prevent banging in wind.
Consider adding transom windows above the door or skylights to the roof to promote airflow and natural light.

Proper roof drainage, moisture barriers and overhangs will help your outdoor shower last. Take special care sealing around doors, windows and penetrations.

Install Plumbing and Electric

With the structure complete, it’s time to add plumbing and power:

Have a licensed plumber connect hot and cold supply lines from the house to shower valves and shower head.
Make sure to pressure test for leaks before covering pipe trenches. Insulate hot water line.
Install PVC drain pipe with proper slope to remove wastewater from shower floor.
An electrician can add lighting and a waterproof GFCI outlet on a dedicated circuit per code. Conduit wiring protects cables.
For solar power, add a solar panel wired to a 12V battery powering LED lights and a water pump.

Follow all local plumbing and electrical code requirements, including those for grounding and GFCI circuits near water sources. Doing this professionally ensures safety and function.

Add Finishing Touches

The finishing details take your outdoor shower from construction phase to oasis:

Select shower flooring that is non-slip like textured ceramic tile, pebbles, or grooved concrete.
Use waterproof shower curtains from weighted fabric, smooth vinyl, or bamboo matchstick style.
Hang wall-mounted caddies conveniently inside for shampoo, soap and razors.
Add a mirror secured to the wall away from direct water spray for shaving or makeup.
Consider heating options like radiant floor heat or wall-mount panel heater to extend your season.
Install shelving, hooks, benches or other extras to suit your needs.
Caulk all seams and openings thoroughly with a flexible outdoor sealant.
Let curing finishes fully dry before first use according to product directions.

Adding personalized touches makes your outdoor shower unique. Focus on waterproofing, convenience and comfort.
