Installing a bathroom shower bench can be a fantastic way to enhance both the functionality and safety of your shower area. Whether you're looking to provide a comfortable seating option for yourself or a loved one, or simply wanting to create a more accessible and user-friendly space, this guide will walk you through the entire process step-by-step. From planning and preparation to installation and finishing touches, we'll cover everything you need to know to successfully install your own bathroom shower bench.

Planning Your Shower Bench

Before you begin, it's essential to plan your shower bench carefully. Here are some key considerations:

1. Space and Layout

Ensure that your shower stall is large enough to accommodate the bench. A standard rectangular shower stall should be at least 52 inches by 36 inches in size to avoid bumping your shins on the seat. If you're planning to install a corner bench, you'll need to consider the angles and corners where water might accumulate.

2. Height and Depth

The height of your bench should be about 15 inches to ensure it's comfortable for everyone in the household. The depth should be around 12 to 14 inches deep, which is a comfortable size even for taller individuals.

3. Material Selection

You can choose from various materials for your bench, including wood, ceramic tile, or even pre-fabricated benches. Each material has its own set of advantages and challenges. For example, ceramic tile is durable and attractive but requires proper waterproofing and framing.

4. Waterproofing

Waterproofing is crucial when installing a shower bench to prevent leaks and ensure safety. You can use topical membranes like Hydroban or Redgard, sheet membranes such as Kerdi, or topical boards like Kerdi-board.

Preparing Your Materials

Once you've planned your shower bench, it's time to gather all the necessary materials:

1. Lumber

Standard 2-by-4-inch lumber is commonly used for framing the bench. You'll need to size it so that it's one inch shorter and narrower than the finished shower seat size to allow room for plywood, waterproof membrane, cement board, and tile.

2. Plywood or Cement Board

Use plywood or cement backer board as the base of your bench. Cement board is particularly recommended because it provides a solid surface for tile installation and helps in creating a waterproof barrier.

3. Tile

Choose your tile material based on durability and aesthetic appeal. Ceramic tile is a popular choice but you can also use granite, real or cultured marble, or laminates.

4. Waterproofing Materials

Select a suitable waterproofing material such as vinyl membrane, liquid membrane (e.g., Hydroban or Redgard), sheet membrane (e.g., Kerdi), or topical board (e.g., Kerdi-board).

Framing Your Shower Bench

Framing your shower bench correctly is essential to prevent water leaks and ensure structural integrity:

1. Square Frame Box

Build a square frame box out of 2×4's for a simple bench design. If you're building a corner bench, create a triangular or arced frame accordingly.

2. Substrate Installation

Place your substrate (cement board or drywall) around the frame. Ensure that it's securely attached to prevent any movement during tile installation.

3. Framing Tips

• Slope the Top: Slightly slope the top of the seat toward the center of the shower to eliminate standing water after showering.
• Overhang: Frame the bench so that there's an overhang for the bench top. This will help in creating a smooth surface for tile installation and prevent water from accumulating at the edges.

Waterproofing Your Shower Bench

Waterproofing is a critical step in ensuring that your shower bench remains safe and functional:

1. Vinyl Membrane

Use a vinyl membrane to create a waterproof barrier. This membrane should cover the shower floor and run up the front of the seat and over it.

2. Liquid Membrane

Apply a liquid membrane such as Hydroban or Redgard over the face of the front and top of the bench, as well as a couple of inches up the wall. This will provide additional protection against water leaks.

3. Sheet Membrane

Use a sheet membrane like Kerdi if you're using traditional waterproofing methods behind your substrate. Ensure that it's properly sealed at all angles and corners to prevent leaks.

Installing Tile

Once your bench is framed and waterproofed, it's time to install tile:

1. Tile Base

Cover the entire seat with cement backer board for a tile base. Attach the cement board using a cement mixture to avoid puncturing the water barrier membrane with nails.

2. Tile Installation

Use the same cement mixture to set the tile as you used for the cement backer board. Ensure that the tile is properly aligned and securely attached to prevent any movement during use.

Assembling Pre-Fabricated Benches

If you prefer not to build your own bench, pre-fabricated benches are available:

1. Fold-Down Benches

Fold-down benches like those from HealthSmart are convenient and easy to install. They come with instructions that guide you through assembling them step-by-step.

2. Wall-Mounted Benches

Wall-mounted benches attach directly to your wall substrate. They require deck mud on top and can be tiled for a seamless look.

Final Touches

After installing your shower bench, there are a few final touches to consider:

1. Adjusting Height

Adjust the height of your bench according to the user's needs. Most benches come with adjustable legs that can be set to different heights.

2. Securing Legs

Ensure that the legs of your bench are securely attached to prevent any movement during use. Use suction cups on the bottom of each leg for added stability.

3. Testing

Test your bench by simulating a shower environment. Check for any leaks or water accumulation around the edges or corners.

Conclusion

Installing a bathroom shower bench is a rewarding DIY project that can significantly enhance your shower experience. By following these steps—planning carefully, preparing materials, framing correctly, waterproofing thoroughly, and installing tile—you can create a safe and functional shower bench that meets all your needs. Whether you choose to build your own bench or opt for a pre-fabricated one, this guide has provided you with everything you need to know for a successful installation.
