Replacing a bathtub on a concrete slab can be a challenging task, but with the right tools and techniques, it can be done efficiently. In this guide, we will cover the steps involved in replacing a bathtub on a concrete slab, including preparing the area, removing the old bathtub, installing the new bathtub, and finishing the job.
Tools and Materials Needed:
Utility knife
Hammer
Pry bar
Reciprocating saw
Screwdriver
Adjustable wrench
Channel locks
Silicone caulk
Plumber’s putty
Caulk gun
Bathtub installation kit
Bathtub
Step 1: Prepare the Area
Before you start removing the old bathtub, you need to prepare the area around it. Turn off the water supply to the bathtub and disconnect the drain pipes. You can use a reciprocating saw to cut the pipes if necessary. Remove any fixtures or attachments on the bathtub, such as the spout, handles, and drain cover.
Next, remove the caulk around the bathtub using a utility knife. This will make it easier to remove the bathtub without damaging the surrounding tiles or walls. Use a hammer and pry bar to remove the tiles around the bathtub, exposing the edges of the bathtub. Be careful not to damage the concrete slab underneath.
Step 2: Remove the Old Bathtub
Now that you have prepared the area, it is time to remove the old bathtub. First, locate the screws that hold the bathtub in place. These are usually located at the corners of the bathtub and may be covered with caulk or tiles. Use a screwdriver to remove the screws.
Once the screws are removed, the bathtub should be loose. Use a pry bar to lift the bathtub off the concrete slab. If the bathtub is stuck, use a reciprocating saw to cut through any adhesive or nails that may be holding it in place.
Step 3: Install the New Bathtub
Before installing the new bathtub, make sure that the area is clean and free of debris. Apply a thin layer of plumber’s putty around the drain hole and install the new drain cover. Next, apply a layer of silicone caulk around the edge of the bathtub where it will contact the concrete slab.
Carefully lower the new bathtub onto the concrete slab, making sure that it is level. Use a level to check that the bathtub is even on all sides. Secure the bathtub to the concrete slab using the screws that came with the bathtub installation kit. Make sure that the screws are tight, but do not overtighten them as this can crack the bathtub.
Step 4: Finish the Job
Once the new bathtub is securely in place, it is time to finish the job. Apply a layer of silicone caulk around the edge of the bathtub where it meets the wall or tiles. Smooth the caulk with your finger or a caulk smoothing tool. Allow the caulk to dry completely before using the bathtub.
Finally, reinstall any fixtures or attachments that you removed in step 1, such as the spout, handles, and drain cover. Turn on the water supply and check for any leaks. If everything looks good, you’re done!
Conclusion
Replacing a bathtub on a concrete slab may seem daunting, but with the right tools and techniques, it can be done efficiently. By following the steps outlined in this guide, you can replace your old bathtub with a new one in no time. Remember to take your time and be careful when removing the old bathtub and installing the new one. With a little patience and effort, you can have a brand new bathtub that will last for years to come.
