How to Make a Shower Bench Seat How to Make a Shower Bench Seat
A shower bench seat is a great addition to any bathroom. Sit back and relax under the hot spray after a long day at work, or use your shower bench seat to keep bath items within reach.
These instructions presume the shower stall is already in place. Here are some of the things you will need to complete this project.
Step 1 - Measuring and Making Plans
Measure the shower stall and decide where you want your shower bench seat. In most cases, the best place for is the corner of the shower stall, making the seat triangle-shaped. Next, use a bucket or an old chair to determine a comfortable height for the shower bench seat. Based on your measurements, draw a plan and buy your materials.
Step 2 - Framing
According to your plan, mark the position of the shower bench seat. Build the frame, keeping in mind that there needs to be a slope of about 0.5inches per 12-feet. Anchor the frame to the back of the shower stall and then apply silicone everywhere wood meets tile to prevent leakage. Do this in the subsequent steps as well.
Step 3 - Attach the Side and Sub-Seat
Measure and cut 2-pieces from the 0.75-inch plywood. 1 piece is the sub-seat and the other is the side. Attach both pieces to the frame using galvanized screws. Once again, seal everything with silicone.
Step 4 - Waterproofing
Lay the PVC liner over the sub-seat and down the side of the shower bench seat. Fasten it securely. Use silicone on the edges to keep water from seeping in underneath the liner.
Step 5 - Adding the Backer Boards
Cut your backer boards to size and attach them in the same manner as the plywood pieces in Step 3.
Step 6 - Tiling and Grouting
With your trowel, coat the backer boards with a thin layer of mortar. Next lay the ceramic tile you chose. Let the tile set for at least 48 hours. Once the tile is set, mix some grout and smooth it into the seams using a sponge. After 30 minutes, wipe the tiles with a clean sponge until they are clear. Wait 24 hours to seal the grout.
If you wish to use marble or granite for the shower bench seat instead, you do not need a backer board. Just spread a thin layer of mortar over the plywood sub-seat, put the marble or granite into place, then set a heavy object on top.
Wait 3 to 4 days for the mortar to dry before you run any water in the shower. It is advisable to contact a plumbing professional before you do any drilling. You could accidentally puncture a pipe or cause other damage if you do not.
