What Will You Need?

Before getting started, gathering all the necessary materials and tools is important. Here are some of the essentials you will need:

  • Plywood or solid surface for bench top
  • Wood screws
  • 2×4 wooden studs
  • Level
  • Power drill with drill bits and screwdriver attachments
  • Measuring tape
  • Saw (circular or jigsaw)
  • Sandpaper or sander

Once you have all the materials and tools ready, it’s time to start building your floating shower bench.

10 Easy Steps on How to Build a Floating Shower Bench

Step 1: Determine the Location and Size of Your Bench

The first step is determining where you want your floating bench placed in your shower.

Consider the size of your shower space and any existing fixtures or obstacles that may affect its placement. Choosing a location that allows enough room for comfortable seating without obstructing other features in your bathroom is important.

Next, decide on the size of your bench based on how many people will be using it and the available space.

A standard bench size is around 18-20 inches in height and 12-14 inches in depth, and the length can vary depending on your preference and available space.

Step 2: Measure and Cut Your Materials

Using a Measuring Tape

Using a measuring tape, carefully measure and mark the dimensions of your bench on the plywood or solid surface. Use a saw to cut out the top piece according to your desired size.

Next, measure and cut two pieces of 2×4 wooden studs to create the frame for your bench. The frame should match the dimensions of your bench top.

Step 3: Sand Down Your Materials

After cutting the plywood or solid surface and the 2×4 wooden studs to the desired dimensions, the next step is to sand down all your materials. Sanding is crucial as it ensures that the surfaces are smooth and free from splinters, which can be particularly hazardous in a wet environment like a shower.

Use a piece of sandpaper or an electric sander to smooth the edges and surfaces of all the pieces.

Start with a coarse grit to remove any large imperfections, then move to a finer grit for a smooth finish.

Make sure to wipe away any dust or debris after sanding, as this will help the assembly process go more smoothly and ensure a better fit.

Step 4: Assemble the Frame

Lay out the cut pieces of 2×4 studs on a flat surface to form a rectangular frame. This frame will support the bench top and needs to be sturdy enough to hold weight. Begin by attaching the shorter pieces of the frame to the longer pieces using wood screws. It’s essential to pre-drill holes for the screws to prevent the wood from splitting.

Use wood glue for extra reinforcement. Make sure the frame is square by measuring diagonally from corner to corner. Both measurements should be equal; adjust as necessary before tightening the screws fully.

Step 5: Attach the Bench Top to the Frame

Using Wood Screws

With your frame assembled, place it on the underside of the bench top and ensure it is properly aligned. Secure the bench top to the frame using wood screws. Again, pre-drill the holes to avoid splitting the wood, and space the screws evenly around the perimeter for maximum stability.

If using a solid surface material for the bench top, you may need to use specialized screws or anchors depending on the material’s requirements.

Step 6: Prepare the Shower Wall

Before mounting the bench, the shower wall must be prepared to support the weight. If your shower does not already have wooden support studs behind the wall, you may need to install them. Use a stud finder to locate existing wall studs and mark their positions.

If necessary, cut out a wall section to add horizontal blocking between the vertical wall studs. This blocking will serve as the mounting point for your bench, ensuring it is secure and capable of bearing weight.

Step 7: Mount the Frame to the Wall

Position the assembled bench frame against the prepared wall at the desired height. Ensure that it is level before securing it.

Use a power drill to drive long wood screws through the frame and into the wall studs or horizontal blocking.

For added security, use metal brackets or steel mounts designed for floating benches. Make sure all screws and brackets are tightly fastened.

Step 8: Seal the Bench Joints

To ensure the longevity of your floating shower bench and to prevent moisture from seeping into the wood, it’s important to seal the joints where the bench meets the wall.

Apply a waterproof sealant or silicone caulk along the edges and seams, making sure to smooth it out for a clean finish. This will help protect the materials from mold and mildew, extending the life of your bench.

Step 9: Apply a Waterproof Finish

Apply a Waterproof Finish

Once the bench is securely mounted and sealed, apply a waterproof finish to the entire surface. This could be a clear waterproofing sealant, a coat of marine-grade varnish, or another water-resistant finish suitable for bathroom use.

Follow the manufacturer’s instructions for application and drying times. This will further protect the bench from water damage and ensure it remains durable and attractive.

Step 10: Test and Enjoy Your Bench

After the waterproof finish has completely dried, it’s time to test the bench. Gently apply pressure to different bench areas to ensure it is firmly attached and does not wobble.

Once you are confident in its stability, your floating shower bench is ready for use. Enjoy the added convenience and comfort it brings to your shower experience.

By following these steps, you can create a functional and stylish floating shower bench that enhances the aesthetics and practicality of your bathroom.

5 Additional Tips and Tricks

  1. Choose the Right Materials: Ensure you select moisture-resistant and durable materials, such as teak wood or marine-grade plywood, to withstand the humid environment of a shower.
  2. Use a Waterproof Sealant: To prevent water damage and prolong the bench’s lifespan, apply a high-quality waterproof sealant to all surfaces.
  3. Secure the Mounting Brackets: Securely install strong mounting brackets into the wall studs to provide adequate support and prevent the bench from collapsing under weight.
  4. Slope the Bench Slightly: Design the bench with a slight slope towards the shower floor to facilitate water runoff and prevent pooling, which can lead to mildew and mold growth.
  5. Regular Maintenance: Regularly inspect and maintain the bench, reapplying sealant if necessary and checking for any signs of wear to ensure it remains safe and sturdy.

With these additional tips and tricks, you can ensure that your shower bench is not only functional but also durable and long-lasting.

5 Things You Should Avoid

  1. Using Non-Waterproof Materials: Avoid using materials that are not designed to withstand moisture. These materials will degrade quickly in the humid environment of a shower, leading to structural failure and potential safety hazards.
  2. Ignoring Weight Capacity: Do not overlook the weight capacity of your bench. Ensure that the bench and its mounting hardware can support the weight of individuals who will be using it to avoid accidents and injuries.
  3. Improper Sealing: Failing to apply a proper waterproof sealant can result in water penetration, leading to rot, mold, and mildew. Always make sure every part of the bench is thoroughly sealed.
  4. Incorrect Mounting: Avoid mounting the bench into drywall or insufficiently sturdy surfaces. It is crucial to anchor the bench securely into wall studs to provide the necessary support and prevent detachment.
  5. Neglecting Regular Inspections: Do not neglect periodic inspections and maintenance of your shower bench. Regular checks for signs of wear, sealing integrity, and overall stability are essential to ensure safety and longevity.

By avoiding these common pitfalls, you can build a safe and reliable floating shower bench that will provide comfort and convenience for years to come.

Conclusion

How to build a floating shower bench can be a rewarding home improvement project that enhances the functionality and aesthetic appeal of your bathroom.

By carefully selecting the right materials, applying a high-quality waterproof sealant, and securely mounting the bench using strong brackets, you can ensure that your bench is both durable and safe.

Implementing a slight slope in your design will aid in water drainage, preventing unwanted water accumulation and associated issues like mold. Regular maintenance and inspections are crucial to uphold the integrity and longevity of your bench.

Simultaneously, avoiding common mistakes such as using non-waterproof materials, improper sealing, and inadequate mounting will safeguard against potential hazards.

By following these guidelines, you can create a stylish, robust, and long-lasting floating shower bench that will provide comfort and convenience for years to come.
