If you’re looking to renovate your bathroom, one of the essential components to consider is the shower base. A shower base can add both style and functionality to your bathroom, but installing one can be a daunting task. In this article, we’ll guide you through the process of installing a shower base on a wooden floor, step-by-step.
Types of Shower Bases

Before we dive into the installation process, it’s crucial to understand the different types of shower bases available. This knowledge will help you make an informed decision on which shower base is best suited for your needs.
Acrylic Shower Base
Acrylic shower bases are lightweight and easy to install. They come in a variety of colours and shapes, making them a popular choice for those looking to add a touch of style to their bathroom. Acrylic shower bases are also affordable, making them an excellent option for those on a budget.
Fibreglass Shower Base
Fibreglass shower bases are another popular choice due to their durability and ease of maintenance. They come in a range of colours and designs, making them easy to match with your bathroom’s decor.
Tile-Ready Shower Base
Tile-ready shower bases are made from a mixture of concrete and fibre, making them sturdy and long-lasting. They’re designed to be tiled over, allowing you to customise the appearance of your shower base to match the rest of your bathroom.
Stone Resin Shower Base
Stone resin shower bases are a high-end option, offering both durability and style. They’re made from a combination of crushed stone and resin, resulting in a sturdy and long-lasting shower base.
When choosing a shower base, consider the size of your bathroom, your budget, and the overall style you’re trying to achieve. Now that you have an idea of the different types of shower bases let’s move on to preparing your wooden floor.
Preparing the Wooden Floor
Before installing a shower base, you need to ensure that the wooden floor is sturdy and able to support the weight of the shower base and user. Follow these steps to prepare the wooden floor for installation:
Step 1: Remove the old shower base
If you’re replacing an existing shower base, the first step is to remove it. Use a pry bar or hammer to remove any tiles or adhesive, and then lift the old shower base out.
Step 2: Check the condition of the wooden floor
Inspect the wooden floor for signs of rot, damage, or degradation. If the floor is in poor condition, you may need to replace it before installing a new shower base.
Step 3: Level the floor
Use a spirit level to check that the floor is level. If it’s not level, you’ll need to use a self-levelling compound to even it out.
Step 4: Reinforce the floor
If the floor is not strong enough to support the weight of the shower base, you may need to reinforce it. This can be done by adding additional floor joists or plywood.
Step 5: Install a vapor barrier
To prevent moisture from seeping into the wooden floor, install a vapor barrier. This can be done by laying a layer of plastic sheeting over the wooden floor.
By following these steps, you’ll ensure that your wooden floor is prepared for the installation of the shower base. Now that the floor is ready let’s move on to the installation process.
Installing the Shower Base
After preparing the wooden floor, you’re now ready to install the shower base. Follow these steps to ensure proper installation:
Step 1: Check the drain
Before installing the shower base, check the drain to ensure it’s in good condition. If it’s damaged, you’ll need to replace it.
Step 2: Install the drain
Insert the drain into the hole in the shower base, making sure it’s centered.
Step 3: Apply adhesive
Apply a generous amount of adhesive to the bottom of the shower base. Make sure it’s evenly distributed.
Step 4: Set the shower base in place
Carefully set the shower base in place, making sure it’s level and centered. Apply pressure to ensure the base is securely attached to the floor.
Step 5: Secure the shower base
Use screws to secure the shower base to the wooden floor. Make sure the screws are evenly spaced and not too close to the edge of the base.
Step 6: Seal the edges
Apply silicone sealant around the edges of the shower base to prevent water from seeping through.
Step 7: Install the shower walls
Once the shower base is installed, you can install the shower walls. Follow the manufacturer’s instructions to ensure proper installation.
Tips and Tricks for Proper Installation
Here are some tips and tricks to ensure proper installation of your shower base:
Use the right tools and materials
Make sure you have all the tools and materials you need before starting the installation process. This will ensure that you don’t have to stop halfway through to go and get something.
Follow the manufacturer’s instructions
Make sure you read and follow the manufacturer’s instructions carefully. This will ensure that the shower base is installed correctly and will function as intended.
Check for leaks
After installation, check for leaks by running water through the drain. If you notice any leaks, fix them immediately.
Hire a professional
If you’re not confident in your ability to install the shower base yourself, consider hiring a professional. This will ensure that the shower base is installed correctly and will function as intended.
By following these tips and tricks, you’ll ensure that your shower base is installed correctly and will last for years to come.
Sealing and Finishing
Once the shower base is installed, it’s essential to seal and finish it properly. This will help prevent water from seeping underneath the base, which can lead to rot and other damage. Follow these steps to seal and finish your shower base:
Step 1: Apply silicone caulk
Apply a bead of silicone caulk around the edges of the shower base where it meets the wall. Be sure to use a caulk that’s specifically designed for use in bathrooms and that matches the colour of your shower base.
Step 2: Smooth the caulk
Use your finger or a caulk smoothing tool to smooth out the silicone caulk and remove any excess.
Step 3: Apply grout sealer
If you have a tile-ready shower base, apply a grout sealer to the tiles and grout to protect them from water damage. Follow the manufacturer’s instructions for best results.
Step 4: Apply a waterproofing membrane
Apply a waterproofing membrane to the shower base to prevent water from seeping underneath. This can be done using a paintbrush or roller.
Step 5: Allow the sealer to dry
Allow the sealer to dry completely before using the shower. This can take several hours, so be patient.
By following these steps, you’ll ensure that your shower base is properly sealed and finished, protecting it from water damage and ensuring its longevity.
Testing and Troubleshooting
After installing your shower base, it’s essential to test it for leaks and troubleshoot any problems that may arise. Here’s how:
Step 1: Fill the shower with water
Fill the shower with water, being careful not to splash any water outside the shower.
Step 2: Check for leaks
Check for leaks around the shower base, the edges where the base meets the wall, and the drain. If you notice any leaks, identify the source and make the necessary repairs.
Step 3: Troubleshoot common problems
If you encounter any problems during the installation process, such as an uneven shower base or difficulty in aligning the drain, consult the manufacturer’s instructions or seek professional help.
Step 4: Test the drainage
Test the drainage by running water through the shower and checking that it drains properly. If there are any issues, such as slow drainage or clogs, consult a plumber.
By testing and troubleshooting your shower base, you’ll ensure that it’s functioning correctly and that any problems are addressed promptly. With these steps, you’ll have successfully installed a shower base on a wooden floor, adding both style and functionality to your bathroom.
