Replacing a bathtub with a shower can transform the functionality and style of your bathroom. Whether you’re looking to create more space, improve accessibility, or update your bathroom’s look, this project can make a big difference. If you’re considering making this change, follow this step-by-step guide to ensure a smooth and successful bathtub-to-shower conversion.
Step 1: Plan Your Design
Before starting, plan the layout and design of your new shower. Consider the following:
Shower Size: How much space do you have available? Standard shower stalls are typically 36″ x 36″, but you can opt for larger or smaller sizes depending on your needs.
Style and Materials: Choose the style, tile, and fixtures for your shower. Do you want glass doors or a shower curtain? Will you use ceramic, porcelain, or stone tiles for the walls and floor?
Drain Placement: You may need to adjust the drain location, especially if the bathtub and shower drain are in different positions.
Consult with a professional if you’re unsure about the layout or plumbing changes.
Step 2: Gather Tools and Materials
Before starting the demolition, gather the tools and materials you’ll need. Here’s a basic list:
Screwdrivers
Wrenches
Utility knife
Reciprocating saw
Crowbar
Pipe wrenches
Shower base or pan
Shower walls or tiles
Showerhead, faucet, and hardware
Waterproof caulk or grout
Plumbing tools (for drain and water connections)
Make sure you also have a tarp or plastic sheeting to protect the surrounding areas.
Step 3: Turn Off the Water Supply
Safety is key. Shut off the water supply to your bathroom before beginning any work. This ensures you won’t accidentally flood the bathroom during the demolition or installation phases. If you’re unsure how to turn off the water supply, locate the main water shutoff valve for your home.
Step 4: Remove the Old Bathtub
The next step is to carefully remove the existing bathtub. Here’s how to do it:
Disconnect the Drain and Water Lines: Use a wrench to disconnect the drain from the plumbing. Remove any water supply lines leading to the tub.
Remove Surrounding Walls: If there are tiles or drywall around the bathtub, use a utility knife to cut through the material. If it’s a tub surround, remove any screws or nails that are holding it in place.
Cut the Tub Free: Use a reciprocating saw to cut the bathtub from its base. Once it’s free, carefully lift it out of the space with help, as it can be heavy.
Be sure to wear protective gloves and goggles while removing the bathtub.
Step 5: Install the Shower Base or Pan
Once the bathtub is removed, it’s time to install the shower base or pan. Here’s how:
Prepare the Subfloor: Clean and level the area where the new shower base will sit. If the subfloor is damaged, repair it before proceeding.
Install the Shower Base: Place the shower base into the prepared area. Make sure it fits snugly and is level. You may need to add mortar or adhesive underneath the base to keep it in place.
Connect the Drain: Align the shower base drain with the existing plumbing. Use a pipe wrench to secure the drain assembly.
Check for leaks by running water through the drain before moving on to the next steps.
Step 6: Install Shower Walls or Tiles
Now it’s time to install the shower walls or tiles. Here’s what you need to do:
Shower Wall Panels: If you’re using pre-fabricated shower wall panels, follow the manufacturer’s instructions for installation. These panels typically snap into place and require minimal cutting.
Tiling: If you’re tiling the shower walls, start at the bottom and work your way up. Apply a layer of thin-set mortar and use a tile cutter to make any necessary cuts. Leave small gaps between tiles for grout.
Waterproofing: Make sure to use a waterproofing membrane or backer board to protect your walls from water damage. Proper waterproofing is essential to avoid mold or mildew growth in the future.
Allow the grout or adhesive to dry fully before proceeding to the next step.
Step 7: Install Shower Fixtures and Hardware
Once your shower walls are complete, it’s time to install the fixtures. Here’s what to do:
Showerhead and Faucet: Install the showerhead and faucet according to the manufacturer’s instructions. This may involve connecting the water lines and securing the faucet handle and showerhead to the wall.
Shower Doors or Curtain Rod: If you’re installing a shower door, follow the manufacturer’s instructions for installation. Alternatively, you can install a shower curtain rod for a more flexible option.
Ensure all fixtures are securely installed and that the water flows properly.
Step 8: Seal and Caulk
After everything is in place, apply waterproof caulk along the edges of the shower where the walls meet the shower base, as well as any seams where water might leak. This will prevent water from seeping into the surrounding walls and floor.
Make sure the caulk is smooth and even to avoid gaps that could lead to water damage.
Step 9: Test the Shower
Before you finish, test the shower to ensure everything works properly. Turn on the water and check for any leaks around the drain, faucet, and showerhead. Make sure the water flows smoothly and the temperature controls work correctly.
Step 10: Clean Up and Enjoy
Once you’ve confirmed everything is functioning properly, clean up the area, remove any protective coverings, and dispose of the old bathtub and construction debris. Your new shower should now be ready for use!
Conclusion
Replacing a bathtub with a shower is a great way to modernize your bathroom and create a more functional space. By following these steps and taking your time to plan, prepare, and install properly, you can enjoy a beautiful new shower that suits your needs and enhances your bathroom’s aesthetic. If you’re unsure about any part of the process, consider consulting a professional plumber or home improvement to ensure the job is done correctly.
