How to Build a Shower Pan with Bench
A shower pan with a built-in bench offers a convenient and comfortable showering experience, especially for those with limited mobility. Building a shower pan with a bench yourself can save you money and allow for customized design choices. Here's a comprehensive guide to help you through the process:
1. Planning and Preparation
a) Design and Measurements:
- Determine the dimensions: Measure the available space for your shower and the desired size of the bench. Consider the length, width, and height of the bench for optimal comfort and accessibility.
- Sketch a plan: Draw a detailed plan of the shower pan and bench, including measurements, materials, and desired features. This will help you visualize the final design and ensure you have all the necessary supplies.
- Choose materials: Opt for waterproof materials for the pan, such as concrete, mortar, or a pre-made shower pan kit. For the bench, choose a durable material like concrete, tile, or composite panels that can withstand moisture.
b) Gather Necessary Tools and Materials:
- Tools:
- Level
- Tape measure
- Trowel
- Bucket
- Mixing paddle
- Grinder with diamond blade
- Circular saw
- Safety glasses
- Gloves
- Work boots
- Materials:
- Concrete mix or pre-made shower pan kit
- Waterproof membrane
- Mortar
- Tile adhesive
- Grout
- Sand
- Concrete sealer
- Waterproof sealant
- Waterproof plywood (for the bench)
- Tile or other desired material for the bench
- Reinforcement mesh
2. Building the Shower Pan
a) Prepare the Subfloor:
- Level the subfloor: Ensure the subfloor is level and free of any unevenness. Use a level to check for slopes and adjust accordingly.
- Install a waterproof membrane: Spread a waterproof membrane over the subfloor to prevent water damage. This can be a sheet membrane or a liquid membrane.
- Create a slope: Build a slight slope towards the drain using mortar or concrete. This ensures water flows properly and prevents pooling.
b) Form the Shower Pan:
- Build a formwork: Use plywood or other suitable materials to create a formwork around the shower pan area. Make sure the formwork is sturdy and aligns with the desired dimensions.
- Reinforce the pan: Place reinforcement mesh inside the formwork to add strength and prevent cracking.
- Pour the concrete: Mix the concrete according to the manufacturer's instructions and pour it into the formwork, ensuring a smooth and even surface.
3. Building the Bench
a) Install the Bench Support:
- Create a frame: Build a frame using 2x4s or other lumber to support the bench. Attach the frame to the shower pan walls and reinforce it for stability.
- Add waterproofing: Ensure the bench frame is completely waterproofed using a sealant or waterproof membrane.
b) Construct the Bench Top:
- Cut the plywood: Cut the waterproof plywood to the desired size and shape for the bench top.
- Attach the plywood: Secure the plywood to the bench frame with screws or nails, ensuring it's flush with the top of the frame.
- Install tile or other material: Apply tile adhesive to the plywood and install the desired tile or other material for the bench top.
4. Finishing Touches
a) Tile the Shower Pan:
- Apply tile adhesive: Apply tile adhesive to the cured concrete pan, ensuring even coverage.
- Install tiles: Lay the tiles on the adhesive, ensuring they are level and evenly spaced.
- Grout the joints: Apply grout to the gaps between the tiles to create a smooth and sealed surface.
b) Seal and Finish:
- Seal the shower pan: Apply a concrete sealer to the finished shower pan to enhance durability and water resistance.
- Seal the bench: Seal the bench top with a waterproof sealant to protect it from moisture.
5. Installation and Final Touches:
- Install the drain: After the concrete has cured, install the shower drain according to the manufacturer's instructions.
- Install shower fixtures: Install the shower head, faucet, and other fixtures, ensuring they are properly connected and function correctly.
- Finalize the shower: Once everything is installed and sealed, enjoy your new shower pan with a built-in bench!
Safety Considerations:
- Wear protective gear: Always wear safety glasses, gloves, and work boots when handling tools and materials.
- Follow manufacturer instructions: Carefully follow the instructions provided by the manufacturers of the materials you use.
- Work with a partner: It is recommended to have a helper for certain tasks, such as pouring concrete.
- Be cautious with power tools: Use power tools with caution and ensure they are properly maintained.
By following these steps, you can successfully build a shower pan with a bench and enjoy a personalized and functional showering experience.
