Question: What is the best way to remove a one-piece Fiberglass tub/shower?
Answer: This is a fairly easy project that can be completed by most homeowners. The easiest way to remove it is to use a Saws-all to cut it into pieces small enough to fit through doorways. It is very important to be careful and take the proper safety precautions. Make sure to wear goggles and gloves since the cut will splinter easily. You might also want to use a mask to avoid breathing in the dust and small fibers. Putting a strip of duct tape where you will be making the cut will help alleviate some of the splintering.
The first step is to cut through the drywall about 1-1/2” away from the tub/shower unit so that only a small area of drywall is damaged. Then, with a fine tooth blade slowly cut the unit into pieces that are disposed of easily. Check with your plumbing supply store and replace it with a new remodel unit. We recommend using a unit that can be screwed into place. Units that are glued in place are more susceptible to coming loose in the future. Your final step is repairing the drywall around the edge of the unit.
