With the right materials and a bit of know-how, you’ll be on your way to creating a durable and stylish outdoor shower floor that lasts for years. Let’s jump into the essentials of building a floor that elevates your outdoor shower experience.

Materials for Building an Outdoor Shower Floor

When embarking on constructing an outdoor shower floor, choosing the right materials is pivotal for durability, aesthetics, and safety. Let’s jump into the most recommended materials and their benefits.


Concrete is a popular choice due to its longevity and low maintenance. It’s highly customizable in terms of shapes and textures, allowing you to match the floor with your outdoor decor seamlessly. With proper sealing, concrete resists water, mildew, and slip, making it an excellent material for outdoor shower floors.


Wooden floors offer a warm, natural look that blends perfectly with outdoor environments. Hardwoods like teak, cedar, and ipe are ideal because of their natural resistance to rot and insects. These woods also possess oils that provide an additional layer of protection against water, an essential feature for outdoor shower floors. Ensure the wood is sustainally sourced and treated for outdoor use to maintain its appearance and longevity.


Ceramic or porcelain tiles can give your outdoor shower a unique and customizable appearance. Opt for slip-resistant tiles to ensure safety when the floor is wet. Tiles are resistant to water and easy to clean, making them a practical choice for an outdoor setting. But, installation requires a bit more skill, as proper drainage and sealing are crucial to prevent water damage and slipping hazards.


Natural stone, such as slate, granite, or river rock, adds a luxurious and organic feel to your outdoor shower. Stone is incredibly durable and offers excellent traction when wet, which is perfect for an outdoor shower environment. Each stone type has distinct colors and textures, enabling you to create a truly unique floor. Like tiles, stone requires sealing to maintain its beauty and functionality over time.

When selecting materials for your outdoor shower floor, consider factors like weather conditions, maintenance, safety, and aesthetics. Your choice will impact not only the look and feel of your outdoor shower but also its utility and lifespan. With the right materials, you can enjoy a beautiful and functional outdoor shower that complements your lifestyle and outdoor space.

Planning and Layout

When you decide to add an outdoor shower to your home, Planning and Layout become crucial steps to ensure its success. Before diving into the construction, it’s essential to map out the location, size, and design of the shower. These elements will influence not only the aesthetics and functionality but also the complexity and cost of your project.

Firstly, choose a location that provides privacy yet is accessible from the swimming area or the back door of your house. An ideal spot is one that receives ample sunlight, aiding in the drying process and preventing mildew growth. Also, consider proximity to existing water lines and drainage systems to minimize installation costs and complexity.

Size is another vital consideration. Standard outdoor showers are typically 4×4 feet or 5×5 feet, offering ample space for a comfortable shower experience without occupying too much of your outdoor area. Adjust the size based on your available space and specific needs, keeping in mind any local regulations that might affect your project.

When it comes to layout, the positioning of the showerhead and controls is key. They should be easily reachable and adjustable for users of different heights. Think about including a small bench or ledge for convenience, allowing users to place toiletries or towels.

Incorporate efficient drainage into your layout design to prevent water accumulation and ensure quick drying. A slight slope away from your house and towards the drainage point helps to avoid water damage and pooling.

By thoroughly planning and designing your outdoor shower layout, you’re setting the stage for a more streamlined and efficient building process. This foresight allows for a better integration of your outdoor shower into your home’s world, elevating both aesthetics and functionality.

Preparing the Site

Before diving into the construction of your outdoor shower floor, preparing the site is a crucial step that’ll ensure a smooth installation process. This preparation involves a series of calculated actions, each serving to lay a solid foundation for your outdoor shower.

Choose the Perfect Location
First, you need to select the ideal spot for your shower. It should be a balance between privacy and accessibility. Consider a location that’s shielded from prying eyes yet conveniently accessible from your swimming pool or back door. Sunlight exposure is another factor; a spot that gets plenty of sunlight can help keep the area warm and inviting, as well as aid in quicker drying of the floor and surrounding surfaces.

Level the Ground
Once you’ve pinpointed the location, the next step is to ensure the ground is perfectly level. Uneven surfaces can lead to improper drainage, pooling water, and potential slip hazards. Use a level tool and, if necessary, add or remove soil to even out the terrain. Compacting the ground can also provide a more stable base for your shower floor.

Mark the Area
With the ground level, outline the exact dimensions of your shower. This can be done using string lines or spray paint. The size of your outdoor shower floor will depend on your personal preference and available space, but making sure it’s clearly marked helps to visualize the project and aids in precise material placement.

Prepare for Drainage
Efficient drainage is key to maintaining a clean and safe outdoor shower. Plan for a slight slope — generally a 2% incline away from your house or any structures — to ensure water flows freely away from the shower space. Incorporating a drainage system beneath the shower floor, such as a French drain or a simple gravel bed, can effectively manage water runoff and prevent erosion.

Each of these steps is instrumental in laying the groundwork for a successful outdoor shower floor installation. With careful planning and preparation, you’re well on your way to creating a functional and aesthetically pleasing outdoor shower that enhances your outdoor living experience.

Create a Foundation

Before laying down your chosen material, you need to create a solid foundation. For concrete bases, this involves digging a few inches into the ground and creating a form to pour the concrete into. For wooden or tiled floors, you’ll start with a layer of gravel for drainage followed by a layer of sand to even out the surface.

Ensure Proper Drainage

Proper drainage is critical to prevent water pooling and ensure your shower area remains clean and hygienic. Slope the base slightly away from your home or the main drainage area. Incorporate a central drain if you’re opting for a tiled floor, ensuring it’s connected to your property’s drainage system.

  • Concrete floors should be sealed to prevent water absorption.
  • Wooden floors need a protective coating of water-resistant sealant to guard against rot and mold.
  • Tiled floors require grouting and sealing to prevent water from seeping underneath.

By carefully selecting materials and following these foundational steps, you’re setting your outdoor shower up for years of enjoyment. Each phase, from choosing the right materials to ensuring efficient drainage, plays a pivotal role in the overall success and longevity of your outdoor shower floor.
