A walk-in shower kit is a complete package that includes all the necessary components to install a shower in your bathroom. It typically includes a base or pan, wall panels, a showerhead, and controls. Installing a walk-in shower kit can be a great way to update your bathroom and increase its functionality. However, it can be a challenging task, especially for those who have never done it before. In this article, we will guide you through the installation process, providing you with valuable tips and tricks along the way.

Pre-Installation Preparation

Before starting the installation process, it’s important to prepare the area properly. This will help ensure that the installation process goes smoothly and that the final product looks and functions as it should. Here are some essential steps to take before starting the installation process:

Measure the Area

The first step is to measure the area where you want to install the walk-in shower kit. This will help you determine the correct size and shape of the kit you need. Make sure to measure the length, width, and height of the area accurately.

Gather Necessary Tools and Materials

Once you have the measurements, gather all the necessary tools and materials needed for the installation process. This includes a drill, screwdriver, level, measuring tape, saw, and caulking gun, among others. Ensure that you have all the components of the walk-in shower kit, and read through the installation instructions to familiarize yourself with the process.

Clear the Area of Obstructions

Before installing the walk-in shower kit, clear the area of any obstructions, such as cabinets, shelves, or appliances. This will give you more space to work and prevent any unwanted damage to these items.

Installing the Base

The base of the shower is the foundation on which the rest of the shower is built. Here are the steps to follow when installing the base of the walk-in shower kit:

Positioning the Base

Start by positioning the base in the exact location where you want the shower to be. Use the markings you made during the pre-installation preparation to ensure the base is in the correct position. Check to make sure the base is level and adjust as necessary.

Leveling the Base

Use a level to ensure that the base is perfectly leveled. If the base is not level, the water will not drain properly, and you may experience water buildup or leakage. If the base is not level, use shims to level it out.

Securing the Base

Once the base is level, secure it in place using screws or adhesive, depending on the type of base you have. Make sure to follow the manufacturer’s instructions when securing the base to ensure a secure and stable installation.

Assembling the Walls

After the base is installed, it’s time to assemble the walls of the walk-in shower kit. Here are the steps to follow:

Fitting the Side Panels

Start by fitting the side panels into place. Use a measuring tape to ensure that the panels are in the correct position and level. Check that the panels are flush against the base and secure them in place using screws or adhesive.

Attaching the Back Panel

Next, attach the back panel to the side panels. Make sure that the back panel is level and flush against the side panels. Secure the back panel in place using screws or adhesive.

Sealing the Joints

Finally, seal the joints between the panels using a waterproof sealant. This will prevent any water from leaking between the panels and ensure a watertight seal. Make sure to follow the manufacturer’s instructions when applying the sealant and allow it to dry completely before using the shower.

Installing the Shower Head and Controls

Once the walls are in place, it’s time to install the showerhead and controls. Here’s how to do it:

Attaching the Showerhead

Start by attaching the showerhead to the wall. Follow the manufacturer’s instructions to ensure it is secured correctly. Make sure the showerhead is at the desired height and angle.

Installing the Faucet and Controls

Next, install the faucet and controls. This will require connecting the pipes to the showerhead and controls. Again, follow the manufacturer’s instructions carefully to ensure everything is installed correctly.

Connecting the Plumbing

Finally, connect the plumbing. This includes attaching the pipes to the water supply and the drain. Test the plumbing by turning on the water to make sure everything is working correctly.

Finishing Touches

The final step in installing a walk-in shower kit is to add the finishing touches. This includes sealing the edges, applying caulk, and cleaning the shower.

Sealing the Edges

Seal the edges between the shower walls and the floor with silicone caulking. This will prevent water from seeping through the gaps and causing damage. Make sure to smooth out the caulking to create a seamless appearance.

Applying Caulk

Apply caulk around the showerhead, faucet, and controls to prevent water from seeping through the gaps. Make sure to use a waterproof caulk and smooth it out evenly.

Cleaning the Shower

Finally, clean the shower thoroughly to remove any debris or residue from the installation process. This will ensure that the shower is clean and ready to use. Use a mild cleanser and a soft cloth or sponge to avoid damaging the shower.


Installing a walk-in shower kit can be an excellent way to upgrade your bathroom and create a more modern and functional space. While the installation process can be challenging, following these steps will help ensure that the project is completed successfully. Remember to take your time, follow the manufacturer’s instructions, and seek professional help if needed. With a little patience and effort, you can enjoy a beautiful new walk-in shower in your home.
