Determine where the access panel is to expose the plumbing to your tub. If no access panel is available, it may be necessary to remove a portion of the wall to gain access. When removing drywall, cut away an area with a utility knife to gain access.
Shut the water supply to the bath tub off by turning off the shut-off valves. If no shut-off valves are installed, turn off the main water supply to your home.
Release the pressure in the water lines by opening the hot and cold knobs to your tub. Remove the knobs and spout by removing the set screws with a coordinating bit and cordless screwdriver. Twist the spout off by hand, or it may be necessary to use a wrench.
Cut around the edge of the tub. If your tub has a surround, it may be necessary to remove it prior to the removal of the tub. If your tub has a wall that covers the lip of the tub, it may be necessary to remove a few inches of wall above the entire tub. Remove drywall using a utility knife. This will give you access to the lip and you will be able to see anything that may be stopping the tub from coming loose from the flooring and walls.
Remove the tub from the bathroom flooring. Use a pry bar and wedge it under the front of the tub. Pry the tub away from the flooring. If there is a plastic or silicone seal along the bottom, remove this prior to using the pry bar. Tear away the plastic or rubber seal and score the silicone with a utility knife before using the pry bar to break the seal.
Remove the old tub from the bathroom.
