My bathtub and shower are one single unit - no seams. It was installed when the house was built in 1987. It has lost the shiny finish and soap scum buildup happens fast and it is always unsightly. There even appear to be discolorations that won't clean up. It is time to replace but it is clear a replacement unit will not fit through the bathroom door. The original was installed as the house was built so that ishow they got it in there. It is a smallish bathroom too. There are 2 piece (or multi-piece) units at the big box stores that would fit through the door. But I've seen these in other places and the seams/joints between the walls and at the tub are usually very unsightly and cheap looking. An alternative is to have it ripped out and tiled, which I am considering but just wish I could get a whole new unit replaced and not tiled. I want to keep it as a single tub/shower unit and not convert to tub or shower stall only. Any other options folks want to recommend? Anybody have a replacement unit with seams that they think is appealing? Thanks!
