There’s nothing quite like rinsing off under the sun—or stars—after a day in the pool, a workout, or some serious yard work. An outdoor shower isn’t just a fun luxury; it’s incredibly practical, too. But before you grab a garden hose and call it a day, let’s talk about how to properly install outdoor shower plumbing so it works safely and efficiently for years to come.
Whether you’re going full DIY or planning to bring in the pros, here’s what you need to know.
What Kind of Drainage Do You Need for an Outdoor Shower?
An outdoor shower needs a drainage solution that directs water away from your home and prevents pooling. Common options include gravel pits, French drains, or drainage pipes that lead to a garden or dry well. In some areas, connecting to a home’s sewer or greywater system may be required by code. Be sure to check local regulations before finalizing your setup.
Pick the Right Spot
First, choose a location close to your existing plumbing lines—typically near an exterior wall of your home. This makes it easier (and more affordable) to connect to your home’s water supply. You’ll also want to think about drainage. A flat, permeable area or connection to your yard’s drainage system can help prevent puddles and water damage.
Choose Your Water Type: Cold-Only or Hot & Cold
A cold-only shower is the simplest to install since it usually just requires tapping into an exterior spigot. But if you want warm water, you’ll need to run both hot and cold lines from inside the home. That can involve cutting through walls or running insulated piping outdoors—definitely doable, but a bit more advanced.
Install the Plumbing Lines
Once the location and water setup are decided, the real plumbing work begins. For cold-only setups, you might use PEX or copper piping from the spigot, with a shutoff valve inside to protect against freezing. For hot-and-cold setups, you’ll install a mixing valve and connect to both water lines.
And don’t forget—local building codes may require a backflow preventer or shutoff valve, especially if your shower connects to potable water lines.
Plan for Proper Drainage
Your outdoor shower will need a way to handle runoff. Some setups drain directly into gravel beds or garden areas, while others use a French drain or even connect to the sewer system (depending on your municipality’s rules). This is where having a plumbing expert can save you a big headache later.
Install Fixtures and Test the System
With plumbing in place, it’s time to install your showerhead, controls, and enclosure (if you’re using one). Once everything’s connected, test your system for leaks and water pressure. Make sure all joints are sealed tight, and that the shower turns off completely when not in use.

Can I use PEX for an outdoor shower?
Yes, PEX piping is a popular choice for outdoor showers because it’s flexible, affordable, and easier to install than copper. However, PEX should be protected from direct sunlight and extreme temperatures, which means insulating it or running it through a protective conduit is essential for outdoor use. In colder climates, make sure the lines can be drained or shut off in winter to prevent freezing.
Do You Need Plumbing for an Outdoor Shower?
Not always—it depends on how you want the shower to function. A basic cold-water shower can connect to an existing hose bib with minimal plumbing. However, if you want hot and cold water or a more permanent setup, you’ll need to run dedicated water lines and potentially install valves, a mixing unit, and drainage—making it a full plumbing project.
How Much Does it Cost to Plumb an Outdoor Shower?
The cost to plumb an outdoor shower varies widely based on complexity. A simple cold-water setup might cost around $200–$500, while a full hot-and-cold installation with proper drainage and fixtures can range from $1,000 to $3,000 or more. Costs may increase if trenching, permits, or professional plumbing services are required.
