Step One: Build The Shower Floor

If you’re planning on building a walk in shower, the first step is to build the shower floor. This can be done by using a variety of materials, but the most common material used is concrete.

When building the shower floor, it’s important to make sure that the slope is correct so that water will drain properly. The slope should be about 1/4 inch per foot. Once the slope is correct, you can then add a layer of waterproofing material.

After the waterproofing material is in place, you can then add a layer of mortar and then tile. Make sure that the tiles are installed properly so that they don’t crack or come loose over time.

Step Two: Install The Shower Walls

Assuming you have your subflooring installed and leveled, you’re ready to start working on the shower walls. In order to keep water from seeping behind your wall panels and causing mold or other damage, you need to create a waterproof barrier. We recommend using an acrylic liner for this purpose.

Once you have your liner in place, it’s time to install the wall panels. If you’re using tile, apply mortar to the back of each one before setting it in place. For prefabricated panels, simply follow the manufacturer’s instructions. For either type of wall panel, be sure to use waterproof caulk or grout around the edges where they meet the floor and ceiling.

Step Three: Install The Shower Door

Assuming you have a preformed shower base, the next step is to install the shower door. If you are using a frameless shower door, first put silicone sealant on the top and bottom of the door opening. Then, set the door in place and use a level to make sure it is even. Once it is level, use silicone sealant to attach the door to the wall at the top and bottom.

For a framed shower door, first attach the hinges to the door according to the manufacturer’s instructions. Then, fit the door into the opening and use a level to make sure it is even. Use shims if necessary to make it level. Once it is level, use screws to attach the hinges to the wall studs.


Building a walk in shower without a curb is not as difficult as it may seem. With the right tools and materials, you can easily build a shower that will be both functional and stylish.
