As your bathroom décor becomes outdated and you prepare for a remodel, the old 70’s pink may have to go. You soon realize you can’t just remove the old one tub and replace it as easy as you would replace a sink. Most bathtubs have a flange that runs along the edge where the tub and tile meet. This makes it impossible to remove the bathtub without removing the grout and a portion of the tile on the wall. In addition to the plumbing and demolition, replacing a bath tub is a big job.
