How To Build A Walk In Shower Base: A Practical Guide in 2023

When planning a walk in shower, one of the first things you need to consider is the base. The base is what will support the weight of the shower and the people using it. It needs to be level, sturdy, and waterproof. There are a few different ways that you can build a walk in shower base, and the method you choose will depend on the materials you are using and the size of the shower. In this blog post, we will explore how to build a walk in shower base, so that you can get started on your project.

What You Will Need

If you are planning to build a walk in shower, there are a few things you will need to do before you can start. First, you need to find a good location for your shower. It should be in a place where it will not be obstructed by other objects in the room. Second, you will need to determine the size of the shower base. The base should be large enough to comfortably accommodate two people. Finally, you will need to choose a material for the base. There are many different materials that can be used, but the most common are tile and concrete.

Step One – Plan The Layout Of Your Shower Base

Building a walk in shower base from scratch may seem daunting, but with a little planning and the right materials, it’s actually quite easy! The first step is to plan the layout of your shower base. You’ll need to decide on the size and shape of your base, as well as where you want the drain to be located. Once you have a general idea of the layout, you can begin measuring and marki

Step Two – Install The Shower Base

Installing a shower base is a vital part of building a walk in shower. The base provides support for the walls and ceiling, as well as a waterproof barrier to prevent water damage. There are many different types of shower bases available, so be sure to choose one that is compatible with the materials you are using for your shower.

When installing the shower base, it is important to level it properly. This can be done by using a level or a laser level. Once the base is level, mark the outline of the base on the floor with a pencil or chalk. Then, use a hole saw to cut out the inside of the marked area. Be careful not to cut through any wires or pipes that may be hidden behind the drywall.

Next, apply silicone sealant around the edge of the hole you just cut. Set the shower base into place and press it firmly into the sealant. Wipe away any excess sealant with a damp cloth. Allow the sealant to dry for 24 hours before continuing with the rest of your project.

Step Three – Install The Walls

After the floor is prepped and dry, it’s time to start thinking about walls. For a traditional walk-in shower, you’ll need three walls and a door. The door can be either swinging or sliding, but make sure it’s waterproof. You don’t want any leaks!

As for the material of the walls, that’s entirely up to you. Stone, tile, and glass are all popular choices that will give your walk-in shower a luxurious look and feel. But if you’re on a budget, plain old painted drywall can also work just fine.

Once you’ve decided on the material for your walls, it’s time to start installing them. If you’re working with tile or stone, you’ll need to use thinset mortar to adhere the tiles or stone to the wall. Glass panels can be installed using silicone sealant or metal clips. And if you’re using drywall, simply screw it into place with drywall screws.

Whatever material you choose for your walls, make sure they’re properly sealed and waterproofed so there are no leaks when your shower is in use!

Step Four – Install The Shower Door

Assuming you have already completed the previous steps of building the shower base and walls, it is now time to install the shower door. For a walk in shower, we recommend a glass shower door as it will make the space feel more open and airy.

To install the glass shower door, first attach the door handle to the inside of the shower door using screws. Then, use silicone caulk to attach the top and side rails of the shower door frame to the shower wall. Make sure to apply pressure to ensure a good seal. Finally, insert the glass panel into the frame and use screws to secure it in place.

That’s it! You have now successfully installed a glass shower door on your walk in shower.


Building a walk in shower base is not as difficult as it may seem. With the right tools and materials, you can easily build a sturdy and stylish base for your walk in shower. Follow our tips and you’ll be sure to create a beautiful base that will last for years to come.
