I'm about to start a bathroom remodel. I'm trying to avoid any seams or grouts to make the shower super low maintenance. I like the idea of large format tiles or even slabs for the walls, but even then there has to be a seam as it transitions to the base. From my experience that caulk line between the walls and the shower base are always the most likely place to get gross and eventually start getting mold. Are there any innovative companies that have good solutions?
