How To Build An Outdoor Shower Plumbing

An outdoor shower can be a refreshing addition to any home, providing a way to rinse off after a swim, garden work, or a day at the beach. Building an outdoor shower requires careful planning and execution, particularly when it comes to the plumbing. This article outlines the essential steps for creating a functional and reliable outdoor shower plumbing system.

1. Determine the Water Source and Connection

The first step in planning your outdoor shower plumbing is deciding on the water source. Common options include:

Existing hose bib: This is the simplest and most common option. A hose bib is a faucet connected to your main water supply line, typically located outside your home.
Dedicated line: For a permanent and more reliable connection, consider running a dedicated water line directly from your home's plumbing system to the shower location. This option requires professional plumbing work.
Well or cistern: If you have a well or a cistern, you can connect the outdoor shower directly to this source, but ensure you have adequate water pressure and flow.

Once you've selected your water source, you need to determine the type of connection:

Hose connection: This is the simplest option but requires a hose to reach the shower.
Direct connection: This involves running a pipe directly from the water source to the shower, offering a more permanent and aesthetically pleasing solution.

2. Choose the Right Plumbing Materials

The type of plumbing materials you choose will depend on local building codes, your budget, and the style of your outdoor shower. Some common options include:

Copper pipe: Durable, corrosion-resistant, and aesthetically appealing, copper pipe is a great option for long-lasting outdoor plumbing. However, it can be more expensive than other options.
PEX pipe: Flexible and easy to install, PEX pipe is a cost-effective alternative to copper. It is also resistant to freezing and thawing, making it ideal for outdoor applications.
PVC pipe: Affordable and readily available, PVC pipe is a good option for less demanding applications. However, it is less durable than copper or PEX and can be susceptible to UV damage.

In addition to the piping, you’ll need to select appropriate fittings, valves, and a showerhead.

3. Install the Plumbing System

The installation process will vary depending on the complexity of your plumbing system. For a basic hose connection, follow these steps:

Install the hose bib: If your hose bib is not already in place, contact a plumber to install one at a convenient location near the shower area.
Run the hose: Connect a garden hose to the hose bib and run it to the shower location.
Install the showerhead: Choose a showerhead designed for outdoor use and connect it to the end of the hose.
Install a shut-off valve: Add a shut-off valve near the hose bib to control water flow and prevent leaks.

For a direct connection, you will need to run a pipe from the water source to the shower area. This is a more complex task and may require the help of a professional plumber.

Ensure you properly insulate any exposed pipes, especially in cold climates, to prevent freezing and damage.

4. Consider Drainage

Proper drainage is crucial for preventing water buildup and ensuring a clean and sanitary environment. Ensure the shower area has a suitable drainage system, allowing water to flow away from the shower and towards a designated drainage point:

Gravel bed: A layer of gravel beneath the shower area can help with drainage.
Dry well: A dry well is a pit filled with gravel that collects and disperses water.
French drain: A French drain is a trench filled with gravel and perforated pipe that collects and redirects water away from the shower.
Slope: Ensure the shower area has a slight slope towards the drainage point to facilitate water flow.

In addition to drainage, consider using a shower pan or other water-resistant materials to create a defined shower area and prevent water from spreading.

5. Test and Adjust

Once the plumbing is installed, test the system thoroughly. Turn on the water and check for leaks at all connections. Adjust the showerhead and water pressure to your preference.

Regularly inspect the plumbing system for leaks or damage. Consider adding a winterization kit to protect the system from freezing in cold climates.
