How to Build a Bench Shower Seat

Having a bench shower seat in your shower is not only a good idea for someone that has mobility problems but provides a spot to sit if you become dizzy or just need an extra flat surface to put your feet up. A standard shower usually only comes with a soap dish and maybe grab bars, if requested. You will need to build and install your own bench shower seat for added comfort. Here is how you accomplish building your very own bench shower seat.

Step 1 - Determine Your Seat Material

First step is to determine the type of material you will use as your bench shower seat. Some of the frequently used materials for this type of project include ceramic tile and plastic or resin. Ceramic tile tends to be the best choice as it is durable, wears well and is easy to work with.

Step 2 - Take Your Measurements

Using your tape measure, take the measurements for the bench shower seat. You will build the bench as a box against one of the walls of your shower. Most individuals like to pick the wall facing the shower fixture. A typical shower seat is 14 inches off the ground. The added measurements you will need to take are as follows:

• Length of the seat (do not build a seat that is shorter than 30 inches)
• Width of the seat (do not build a seat that is less than 12 inches)

Step 3 - Frame the Seat

Frame out the seat using your 2x4's.  Make the following cuts:

• Two pieces to the length of the seat
• 4 pieces to the width of the seat
• 4 pieces to the height of the seat

Attach each of the 2x4s using either a hammer and nails or a nail gun. This will create the seat box.  Attach the seat box frame to the bottom and side of the shower.

Step 4 - Add the Drywall

Now, add the drywall (green board) to the bench shower frame, excluding the seat. Screw the green board into the frame. Tape the seams of each of the pieces of drywall. Apply drywall putty using your putty knife to the seams and to the holes created by the screws. Allow the surface to dry for at least 24 hours.

For the seat, you will need to add plywood for extra sturdiness. The plywood can be screwed onto the frame, then covered in green board. Seal the edges with drywall putty for a waterproof seal.

Step 5 - Prep for the Tile

Sand down the putty so that you create a smooth finish. Then, using a hammer and nails, secure the wire mesh to the green board.

Step 7 - Lay the Tile

Apply cement to the mesh and lay the tile. Space the tile using tile spacers and cut the tile around the corner and edges. Allow the tile to sit for at least 24 hours.

Step 8 - Apply the Grout

Grout in between the tiles. Apply an even layer of grout over the entire tile surface. Smooth the grout as necessary.

Step 9 - Clean Up

Clean up your work area before using the shower again.

Note: Dealing with a Fiberglass Shower

If you have a fiberglass shower, you will want to install a fiberglass bench seat. You can purchase a fiberglass bench seat at many of the home improvement centers. There are instructions with each fiberglass bench that you should follow during your installation procedure.
