Step by Step Guide on How to Install a Bathtub
The installation of a bathtub requires precise measurement and accurate placement of parts. Use the bathtub installation diagram provided with the unit.
1. Dry-fit the tub.
Make sure that the bathtub that you ordered fits the space you provided. Check to see if its drain location lines up with the supposed floor P-trap. Be careful when moving the tub to avoid chips and scratches.
2. Install the surrounds as needed.
The alcove bathtub is designed to have surrounding back panels. For this type, you will need to purchase additional panels in the bathroom. If you have a shower bathtub combo, you should also align the shower pipe to the top flange. Use a pipe wrench as needed.
3. Install the supports.
A bathtub will need all the supports that can carry the weight of the tub. A ledger board does just that. It also helps secure the tub if it needs to be attached to the wall.
4. Install the drain.
Ensure that the drain is installed in the bathtub. Use a plumber’s putty to attach the drain and put the necessary gasket to the bottom of the tub. You may use pliers to tighten the parts.
5. Connect the overflow drain.
The overflow drain prevents the overflow of water to the top of the bathtub. Connect all the pipe fittings which provide a way for the water to flow to the drain in case the water keeps on running.
6. Install the bathtub securely.
Place the bathtub so that it is securely resting on the floor. The drain on the floor should connect directly to the drain of the bathtub. This can be very tricky, especially in cases where the question is how to install a bathtub without access underneath.
Secure the bathtub by putting studs in the wall and securing the flange to it. Read the bathtub installation diagram from the manufacturer to ensure proper connection.
You also need to caulk the tub to the surrounding panels.
7. Install all the bathroom fixtures.
You can now install the accessories such as the faucet, handles, and other fixtures as needed. You will also need to connect the drain to the P-trap under it.
8. Secure the tub to the floor.
Use a silicone caulk and run it along the edges between the tub and the floor. This prevents water from going under the tub.
9. Test it out.
You have to wait for 24 hours before testing it out. This is to make sure that all the adhesives have set. In case there is a problem, you may want to look for a possible solution or ask the help of a professional plumber.
