Essential Tools and Materials for Replacing a Bathtub on Your Own
The key to a smooth bathtub replacement lies in having the right equipment and materials ready from the start. Whether you’re removing and replacing or installing a new bathtub, having the correct tools and supplies is crucial for a successful project.
Required Tools
To remove your old tub, you’ll need essential tools like a reciprocating saw, utility knife, pry bar, and tub drain remover. These tools will help you disconnect the drain assembly and remove the tub safely.
For the installation phase, a level, tape measure, cordless drill with appropriate bits, caulk gun, and adjustable wrench are necessary to ensure proper positioning and connection of the new tub.
Safety equipment, including work gloves and safety glasses, is also crucial to protect yourself from sharp edges and debris.
Necessary Materials
The materials required for bathtub replacement include the new bathtub itself, drain assembly components, plumber’s putty, and silicone caulk. You’ll also need 2x4s for support structures, shims for leveling, and screws and nails for securing the tub.
Additionally, pipes and fittings for plumbing connections, floor leveling compound, and grouting materials are necessary to complete the project.
Selecting the Right Bathtub for Your Space
The key to a stress-free bathtub replacement lies in selecting a tub that fits your space perfectly. To achieve this, you need to take accurate measurements of your existing bathtub alcove.
Measuring Your Bathtub Alcove
Before you begin your bathtub replacement, measure your current bathtub alcove around the shower walls. This will help you select the right size tub for your space. Keep in mind that most standard bathtubs are 5-feet long and either 30- or 32-inches wide. Your measurement will be slightly less than those numbers because of the shower wall surfaces (tile, shower surround, etc.).
- Measure the length, width, and depth of your existing tub alcove.
- Account for wall surfaces like tile or surrounds that may affect the actual available space.
Determining Drain Location and Tub Type
Next, determine the drain location of your tub. To find out what type of tub you need, face the alcove. The side that holds the drain opening determines what type of tub you need. If the drain is on the left, look for a left drain tub. If it’s on the right, you need a right drain tub.
- Face the alcove and note whether the drain is on the left or right side.
- Choose a tub that matches your drain location.
Preparation Steps Before Removal
Shutting off the water supply is the first critical step in the bathtub replacement process. This ensures that your workspace remains dry and safe throughout the project.
Shutting Off Water Supply
To begin, locate the shutoff valves for your bathroom. If your bathroom doesn’t have separate shutoff valves, you may need to turn off the main water supply to the entire house. Test that the water is off by turning on the bathtub faucet. Then, open a valve at a lower level in your home to relieve any remaining pressure in the lines. This step is crucial for preventing unexpected leaks or water damage during the replacement process.
Clearing the Work Area
Clearing the bathroom area is essential for a smooth bathtub replacement project. Remove all toiletries, shower curtains, rugs, and decorative items that could be damaged or impede your movement. Protect adjacent surfaces by covering the bathroom floor, toilet, and vanity with drop cloths or plastic sheeting. Ensure proper ventilation by opening windows or setting up fans, as some materials used during installation may release fumes. Organize your tools and materials, and make sure you have a plan for disposing of the old tub.
Disconnecting the Plumbing Fixtures
The process of replacing a bathtub begins with disconnecting the plumbing fixtures, which is crucial for avoiding damage to your home’s plumbing system. This step is essential for a successful replacement.
Removing the Drain Flange and Overflow Cover
To start, you’ll need to remove the drain flange, which may require a specialized tub drain wrench to unscrew it from the drain shoe beneath the tub. Some drains have a visible drain stopper that unscrews, offering access to the drain flange. Use a screwdriver to disconnect and remove the tub’s waste and overflow valve cover. Remove the tub spout since it will be on a portion of the wall you’ll be cutting away.
- Use a tub drain wrench for removing the drain flange.
- Disconnect the overflow valve cover using a screwdriver.
- Remove the tub spout by twisting it counterclockwise or by removing the setscrew.
Accessing and Disconnecting the Drain Assembly
To disconnect the drain assembly, you need to gain access to the underside of the tub. This can be done through an existing access panel or by creating one by cutting into the drywall behind the overflow valve. Use channel lock pliers to disconnect the drainpipe below the tee where the drain and overflow valve meet. If the fittings are galvanized steel, apply a penetrating lubricant to loosen the joints.
- Access the underside of the tub through an existing panel or create one.
- Use channel lock pliers to disconnect the drainpipe.
- Apply penetrating lubricant if the fittings are galvanized steel.
Removing the Old Bathtub
The process of removing the old bathtub demands attention to detail and the right techniques. It’s a crucial step that requires careful planning and execution to avoid damaging the surrounding area.
Separating the Tub from Surrounding Walls
To start, you need to separate the tub from the surrounding walls. This involves removing approximately 6 inches of the wall material above the tub on all three sides. The type of wall material (drywall, tile, or surround) will determine the tools you’ll need. For drywall, use a utility knife and drywall saw. For tiled surfaces, a grout removal tool and a stiff putty knife will be necessary. Always wear safety glasses and gloves during this process.
Once you’ve removed the wall material, you’ll expose the tub flange, which is attached to the studs. Use a pry bar to remove the screws or nails securing the flange to the studs. Work methodically around all sides of the tub. Additionally, cut away any caulk or sealant between the tub and floor with a utility knife.
Extraction Techniques for Different Tub Types
The technique for removing the old tub varies depending on its material. For heavy cast iron bathtubs, it’s often necessary to break them into manageable pieces using a sledgehammer, taking care to wear ear protection and exercise caution. For lighter materials like fiberglass or acrylic, the tub can often be removed whole with some assistance. Use a reciprocating saw to cut up steel, composite, or fiberglass tubs. After removal, clean the exposed alcove area thoroughly, removing any debris that could interfere with the new bathtub installation.
Finally, consider the disposal of the old bathtub. Research local regulations for disposing of or recycling bathtubs, especially for cast iron models. Proper disposal is crucial for a successful renovation.
Preparing the Alcove for the New Tub
With the old tub removed, the next step is to prepare the alcove for the new installation. Proper preparation of the alcove is crucial for ensuring your new tub will be level, stable, and properly supported for years of use.
Cleaning and Inspecting the Subfloor
Begin by thoroughly cleaning the exposed alcove area, removing all debris, dust, and any protruding nails or screws from the studs and floor that could interfere with the new tub installation. Carefully inspect the subfloor for any signs of water damage, rot, or structural weakness. If you discover water damage or soft spots, you’ll need to remove and replace the affected sections to provide a solid foundation for your new bathtub.
Installing Support Structures
Make sure the alcove dimensions match the specifications of your new tub. Install a new 2×4 ledger board along the back wall, precisely leveled and securely fastened to the studs at the height specified by your tub manufacturer. Verify that all studs are plumb and secure, reinforcing or replacing any that show signs of damage or instability. This is also the ideal time to address any plumbing updates or repairs needed, ensuring all pipes are in good condition and properly positioned to connect with your new tub’s drain assembly.
Installing the New Bathtub
Now that the alcove is prepared, we can proceed with installing the new bathtub, a process that involves several key steps to ensure a secure and proper fit.
Setting Up the Ledger Board
A crucial step in supporting the new tub is setting up a ledger board, which bears the weight of the tub along the back wall. To do this, measure and mark the correct height for the ledger board based on your tub’s specifications, typically allowing for the height of the tub’s flange. Then, secure a 2×4 board horizontally to the wall studs using deck screws.
- Measure the height of the tub flange.
- Mark this height below the reference line on each stud.
- Cut a 2×4 to the length of your tub.
- Attach it to the studs on the new reference marks.
Positioning and Leveling the Tub
Before permanently placing your new tub, do a “dry fit” by carefully setting it in the alcove to check for proper fit. Mark reference lines on the studs to indicate the top edge of the tub flange. When ready for final placement, have a helper assist you in setting the new tub onto the prepared surface, sliding it into position. Use a level to check that the tub sits perfectly level in all directions.
Securing the Tub to Wall Studs
Once the tub is positioned and level, secure it to the wall studs by driving galvanized screws or roofing nails through the tub flange at each stud location. Be careful not to overtighten and crack the flange. Ensure the tub’s sound-deadening pad makes full contact with the subfloor to prevent flexing and noise.
- Secure the tub flange to the studs.
- Check that the sound-deadening pad is in full contact with the subfloor.
Connecting the Plumbing to Your New Tub
As we finalize the bathtub installation, connecting the plumbing to the new tub is a crucial step that requires precision to prevent future leaks and ensure proper drainage.
Installing the Overflow Drain Assembly
To install the overflow drain assembly, start by turning the tub on its side according to the manufacturer’s instructions. Apply a ring of plumber’s putty around the underside of the drain flange, then position the drain shoe on the tub’s underside and thread the flange into it from above. Tighten it completely with a drain wrench and remove any excess putty.
Next, place the rubber gasket onto the overflow elbow and position it behind the tub. Attach the cover plate inside the tub to the overflow elbow and gasket behind the tub using the screws provided in the overflow drain assembly kit.
- Ensure all connections are secure to prevent leaks.
- Use the provided screws for a secure attachment.
- Check the manufacturer’s instructions for specific requirements.
Connecting the Main Drain
With the overflow assembly in place, connect the overflow pipe and main drainpipe with a tee fitting where they meet. Carefully move the tub back into place, ensuring not to disrupt the drain assembly. Align the drain and overflow plumbing with the rough-in drain outlet in your bathroom.
Once aligned, connect the pipes and tighten them down snugly, but avoid over-tightening. Test all connections for leaks by filling the tub with a few inches of water, then draining it while inspecting all pipe joints and connections from below.
Finishing the Bathtub Installation
The last stage of your bathtub replacement project involves finishing touches that are crucial for both functionality and aesthetics. With the new tub in place, it’s time to focus on the surrounding areas to ensure a watertight and visually appealing result.
Repairing and Finishing the Walls
Begin by repairing the walls around the tub, installing new water-resistant drywall or cement board as a base for your wall finish. Make sure to secure it properly to the wall studs. When installing wall materials, leave a small gap (approximately 1/8 inch) between the bottom edge of the wall material and the tub flange to prevent water from wicking up into the wall. You can then apply your chosen wall finish, whether it’s tile, fiberglass surround, or another waterproof material, following the manufacturer’s guidelines for proper installation in wet areas.
Applying Caulk and Sealant
Once the wall finishes are complete, apply a continuous bead of silicone caulk along all seams where the tub meets the wall and floor to create a watertight seal. This prevents water infiltration and ensures the longevity of your bathtub installation. Reinstall any fixtures you removed during the process, including the tub spout, faucet handles, and shower head, using Teflon tape on threaded connections to ensure watertight seals.
After completing these steps, turn the water supply back on and test all fixtures, checking carefully for leaks. Make sure to run water through all components of your new installation to verify that the drain functions properly and water flows correctly through all pipes and faucets. Allow all caulk and adhesives to cure completely before using the tub.
