What to do before bathtub removal
Before you start, always make sure the area is well prepared. Put some taped plywood on the floor and cover with a cloth for protection. Remember to shut off the main water pipe and power. Also, remove the toilet and sink if they will get in the way. Moreover, you should measure the dimensions of your tub and doorway. This will help you know what size of tub to get. Also, note the location of your drain pipe beforehand.
How to remove the bathtub drain
Once the water connection is shut, your next task is to unscrew the faucet, drain, and other attachments. To remove the drain flange, use a strainer wrench or a pair of needle-nose pliers. The waste and overflow cover on the sides of the tub should be undone with a screwdriver. A pair of channel lock pliers will be needed to detach the pipes found under the T-shape placed at the intersection of the drain and overflow valve. When the nut joining the drainpipe is loosened, use your hand to unscrew it and lift out the whole section. Now with all these units undone, the tub spout can be safely removed so that your fitting is not blocked.
Separating the tub from the wall
You need to clear the wall so as to reach the nails and screws holding the tub flange to it. To do this, measure out and draw a guideline around your old bathtub on each side. You can also cut out a strip horizontally from the wall using a grinder with a diamond blade in case your wall is tiled. It should be 6-7 inches above the tub flange.
Take caution not to damage the studs or other elements such as pipes and wires placed in those spaces. The individual tiles will pop out individually with the help of a chisel. After this, remove the nails and screws all around the top of the tub and sides with a utility knife and pry bar. In addition, any stringer support hanging on the wall should be removed.
