How to Install a Bath Tub

New Bathtub

As with any major project as installing a bathtub, the first thing to keep in mind is the building codes. These dictate what is acceptable and what is not. With that in mind, installing a bathtub can be a challenge. Some knowledge of plumbing is required as well as wall and floor construction. The next item to make note of is the type of bathtub being installed. If simply replacing the bathtub with a new one of the same make and model, there is less work involved. However, if a style and size change is desired, then remodeling the bathtub area is required. This includes plumbing, wall and floor reconstruction.

Things You'll Need

• Bathtub
• Pipe wrench
• Basket removal wrench
• Utility knife
• Carpenter’s level
• Wood shims
• Teflon tape
• Pry bar
• Scrap piece of wood
• Caulk

Instructions

Removing the old Bathtub

1. 

   Turn off the main water supply to the house. Remove water pressure from the lines by opening the valves. Remove the basket drain with the basket removal wrench. Remove any of the wall material to expose the edge of the bathtub that is next to the studs.

2. Gain access to the plumbing by removing the wall adjacent to the tub where the faucet is located. Use caution when removing the faucet as this could damage the threads on the existing plumbing in the wall. Place an old blanket on the floor to slide the tub onto.

3. Place the scrap piece of wood against the long wall of the tub (for protection) and slide the tub away from the wall with the pry bar. If there is a hang up, check to be certain that all the plumbing is free.

4. remove the tub from the bathroom once the tub is free from the plumbing. This will require some assistance.

Installing the new Bathtub

1. Set the new bathtub in place. Make certain the bathtub is securely against the studs on all three walls. If needed, remove any of the wall material that would hinder the bathtub from reaching the studs in the wall.

2. Level the bathtub with a carpenter’s level. Place shims under the bathtub as needed. Be certain to eliminate any "rocking" of the bathtub.

3. Connect the basket drain and tighten with the basket removal wrench. Wrap the thread of the plumbing with the Teflon tape. Install faucet to the plumbing.

4. Replace wall around bathtub so that it hides the wall flange. Caulk or seal around the bathtub as needed.

5. Turn on the main water supply and check for leaks. Allow water to flow through the drain to be certain it doesn’t leak.

Tips & Warnings

• Always wear safety glasses.

• Smooth the caulking with a wet fingertip wiping off excess.

• Do not attempt to life the bathtub by yourself as this can cause injury.
