How Do You Replace a Shower Tub Combo Step by Step?
Replacing a shower tub combo can transform the look and functionality of your bathroom, offering a fresh, updated space that meets your needs and style preferences. Whether you’re tackling a renovation to fix damage, upgrade outdated fixtures, or simply enhance your home’s value, understanding the basics of this process is essential. While it might seem like a daunting task, with the right approach and preparation, replacing a shower tub combo can be a manageable and rewarding DIY project.
At its core, replacing a shower tub combo involves removing the existing unit and installing a new one that fits seamlessly into your bathroom layout. This process requires careful planning, from selecting the right materials to ensuring proper plumbing and waterproofing. It’s not just about aesthetics; a well-installed shower tub combo can improve safety, increase comfort, and prevent future water damage.
Before diving into the specifics, it’s important to grasp the overall scope of the project and what it entails. This article will guide you through the essential considerations and steps involved in replacing your shower tub combo, helping you prepare for a successful upgrade that revitalizes your bathroom space.
Removing the Old Shower Tub Combo
Begin by turning off the water supply to the bathroom to prevent any accidental leaks or water damage. Next, open the faucet to drain any remaining water in the pipes. Carefully remove the shower curtain or doors to gain unobstructed access to the tub area.
Start by disconnecting the plumbing fixtures attached to the tub, including the faucet, showerhead, and drain assembly. Use appropriate wrenches or plumbing tools to loosen and detach these components. Take care not to damage the supply lines or drain pipe as you will need to reuse or replace them later.
To remove the tub surround or tiles, score the caulk lines around the tub edges with a utility knife and use a pry bar to gently detach the surround panels or tiles from the wall studs. If tiles are present, chisel them off carefully to avoid damaging the drywall or adjacent tiles.
Once the surround is removed, locate and remove any screws or nails securing the tub flange to the wall studs. With assistance, carefully lift the old tub out of the alcove. This step may require cutting the tub into smaller pieces if it is too heavy or if it cannot be removed whole due to space constraints. Use reciprocating saws or angle grinders with caution.
Dispose of the old tub and debris following local regulations, ensuring the work area is clean and free of sharp objects.
Preparing the Area for Installation
After removing the old tub, inspect the subfloor and wall studs for any signs of water damage, mold, or rot. Replace any damaged materials to ensure a solid, level foundation for the new tub installation.
Verify that the plumbing rough-in locations—water supply lines and drain—are compatible with the new shower tub combo. Adjust or relocate plumbing as necessary, keeping in mind the manufacturer’s specifications.
Install or repair the backer board or cement board on the walls around the tub area to provide a moisture-resistant surface for the new tub surround or tile installation. Ensure the backer board is securely fastened to the studs and seams are properly sealed with mesh tape and thinset mortar.
Double-check that the floor is level using a carpenter’s level. Shim or level the floor if required to prevent future drainage issues or tub instability.
Installing the New Shower Tub Combo
Before positioning the new tub, apply a bead of silicone caulk or construction adhesive to the bottom edge of the tub flange to create a watertight seal between the tub and wall studs. Carefully set the tub into place, aligning it with the drain and water supply lines.
Secure the tub flange to the wall studs using corrosion-resistant screws, ensuring the flange is flush and firmly attached. Check for levelness side-to-side and front-to-back, adjusting as necessary with shims under the tub base.
Connect the drain assembly and overflow to the tub, ensuring all gaskets and seals are properly seated to prevent leaks. Reconnect the water supply lines and install the faucet and showerhead according to the manufacturer’s instructions.
Test the plumbing connections by turning on the water and checking for leaks. Address any issues immediately before proceeding.
Finish the installation by sealing the joints between the tub and walls with a bead of mildew-resistant silicone caulk. Smooth the caulk with a wet finger or caulk tool for a professional finish.
