Are you dreaming of a refreshing outdoor shower to complement your eco-friendly home? Building a do-it-yourself outdoor shower can be a rewarding project that enhances your outdoor space while providing a convenient way to rinse off after a day in nature. In this guide, we'll walk you through everything you need to know to create your outdoor shower, from planning the enclosure to installing the plumbing.

Are Outdoor Showers a Good Idea?

Absolutely! Outdoor showers are not only a luxurious addition to your home but are practical for anyone who loves spending time outdoors. They provide an easy way to clean up after gardening, swimming, or hiking, and can even add value to your property.
However, there are a few instances where an outdoor shower might not be the best choice. If you live in a region with extreme weather conditions or have limited outdoor space, you may want to reconsider. But for most homeowners, the benefits far outweigh any potential drawbacks.

Consider the Climate for an Outdoor Shower

Taking the climate into account is critical when deciding whether an outdoor shower is a good idea for your property. In regions with harsh winters, proper insulation and frost-proof fixtures are necessary to prevent pipes from freezing and bursting.

Conversely, in tropical zones with high humidity and frequent rainfall, selecting materials that resist mold and rot is essential for longevity. In extremely dry climates, water conservation becomes a priority, so implementing efficient water-use strategies can make your shower more sustainable. Ultimately, understanding and planning for the local weather conditions ensures that your outdoor shower remains functional and enjoyable all year round.

The enclosure provides privacy and defines the space for your outdoor shower. Aim for a design that's both functional and aesthetically pleasing.

Benefits of Outdoor Showers:

• Convenience: Easy access to a shower without tracking dirt indoors.
• Eco-Friendly: Reduces indoor water usage and can be designed to use greywater systems.
• Aesthetic Appeal: Enhances your outdoor living space with a touch of luxury.

How to Build an Outdoor Shower

General Guidance:

Building an outdoor shower involves several steps, from choosing the location to installing the plumbing. Here’s a brief overview:

1. Choose the Location: Opt for a spot with natural privacy, easy access to water lines, and proper drainage.
2. Establish a Reliable Foundation: Ensure your flooring is secure and well-drained to prevent rot and water buildup.
3. Construct the Enclosure: Build a sturdy enclosure using materials like Trex composite decking for durability, low maintenance, and resistance to water damage.
4. Install the Plumbing: Set up the plumbing with both hot and cold water lines for added comfort.
5. Add Finishing Touches: Enhance your shower with stylish fixtures and outdoor lighting.

When to Build:

Consider building your outdoor shower during warmer months to avoid complications from cold weather affecting the installation process.

Choose the Location

Deciding where to place your outdoor shower is crucial. The location should provide natural privacy, as well as easy access to water lines and proper drainage.

Location Options:

• On a Deck: Offers convenience and integrates well with existing outdoor living spaces.
• Ground Level: Provides flexibility in placement but may require additional work for plumbing and drainage.
• Poolside: Great for a quick rinse after a swim, but may need to be enclosed for privacy.
• Beachfront: Offers stunning views and the ultimate beach experience, but consider weather and potential erosion.

Choosing the Best Spot:

• Privacy: Look for a secluded area or use natural barriers like trees and shrubs.
• Accessibility: Ensure easy access to water lines and proximity to the house.
• Drainage: Select a spot with good drainage to prevent water pooling.

Establish a Reliable Foundation that Drains

A reliable foundation is essential for the longevity of your outdoor shower. Choose materials that resist rot and ensure proper drainage to keep the area dry and safe.

Flooring Options:

• Composite Decking: Trex composite decking is an excellent choice for its durability and resistance to rot. Plus, it's easy to clean and maintain.
• Wood Decking: Traditional wood can be used but requires regular maintenance to prevent rot. Consider using pressure-treated lumber for added protection.
• Stone or Tile: These options provide a more natural and luxurious look, but may require additional sealing to prevent potential erosion.

What kind of drainage do you need for an outdoor shower?

Save

When installing an outdoor shower, effective drainage is important to ensure both functionality and durability. The type of drainage you need depends on the specific conditions of your site. Generally, a slight slope in the shower floor helps direct water away naturally. Using permeable materials such as gravel underneath the flooring allows water to seep through and drain efficiently, preventing pooling and potential water damage.

In areas with less natural drainage or higher water usage, installing a dedicated drain system, like a French drain or a plumbed drain connected to your home's wastewater system, can be essential. This ensures that water is efficiently carried away from the shower area, keeping the space dry and safe while minimizing potential long-term issues.

Ensuring Proper Drainage:

• Design: Incorporate a slight slope in the flooring to direct water away.
• Materials: Use gravel or permeable pavers to facilitate drainage. Avoid solid paving materials that can trap water.
• Plumbing: Install a drain system or use a french drain to direct excess water away from the shower area.

Construct the Enclosure

The enclosure provides privacy and defines the space for your outdoor shower. Aim for a design that's both functional and aesthetically pleasing.

Typical Enclosure Shape and Size:

• Shape: Rectangular or square shapes work well.
• Size: A 3x3 feet space is usually sufficient.

Building the Enclosure:

1. Frame: Build a sturdy frame using treated wood or composite materials.
2. Walls: Attach composite boards made from Trex composite decking or other durable materials.
3. Door: Add a door or curtain for easy access and privacy.

Install the Plumbing

Setting up the plumbing for your outdoor shower involves connecting to your water supply and ensuring a reliable flow of both hot and cold water.

Plumbing Setups:

• Garden Hose: A simple option for cold water showers.
• Water Supply Lines: For a more permanent solution with hot and cold water, connect to your home’s water supply.

Installing the Plumbing:

1. Water Lines: Run pipes from your water supply to the shower location.
2. Showerhead and Valves: Install a showerhead and valves for temperature control.
3. Insulation: Insulate pipes to prevent freezing in colder climates.

Add Finishing Touches
