Step 5 · Detach Tub from Studs
Once the wall is open and the tub's nailing flange is exposed, you need to detach the tub from the wall studs. Look closely along the top edge of the flange for the nails or screws that secure it to the studs. Use a pry bar or the claw of a hammer to pull out the nails. If screws were used, back them out with a drill or impact driver. If the fasteners are rusted or inaccessible, use a reciprocating saw with a metal-cutting blade to cut through them by sliding the blade between the flange and the stud.
