Have cultured marble sink top and spa tub surround white with green swirls. Have Kohler seafoam green tub, corner shower and toilet. Changing out carpet on floor to tile. Nothing matches or is appealing. If I change out tub surround, how do I remove the top section that sits under the tubs top wrap over, Tub is drop in that is cemented to floor. Can I tile UP TO the tub edge. If not and I need to totally remove Cult. Marb. tub top, how do I safely remove it with out damaging the tub. Sits on plywood top and probably liquid nailed to plywood. I like the new travertine look alike porcelain tile. But am open to any suggestions at this point.
