Hi! I have a windowless bathroom that has floor to ceiling tile (in a blue glass mosiac that i think is supposed to make it feel like you are underwater). There is a curbless, doorless shower stall, no tub. The grout is deteriorating and tiles are popping off, and mold appears to be an issue, and it is only 12 years old! I cant stand it. I want to replace it all with something as watertight and with as little grout as possible. I do not care for prefab fiberglass surrounds. What are my options? Any favorites? I like a rustic-modern look... Concrete or maybe some kind of solid surface like... marble or corian or somethimg? Photos of your projects and price estimates more than welcome!
