I have bought a two year old resale house and it has an oval tub installed next to the shower stall. It is not in a corner. The wall on the front side of the tub, from the front edge of the tub to the floor, is just painted drywall with a baseboard at the bottom edge which meets carpet. It gets drips of water on it every time I take a bath and get in and out of the tub. I want to replace it with something waterproof like vinyl or "pretend" marble, but I'm concerned about the thickness of the new wall matching the carpet line. I don't need to recarpet. What would you recommend and how do I go about fixing it? The seam along the lip edge of the tub is not lined up with the sheetrodk. Some of the wall is under the lip and some of it is over the edge of the lip.
