Remodel options needed: Replace bath with shower
I am looking at removing a standard fiberglass bathtub/shower enclosure and installing a tiled shower. What are my options for the base of the shower? I've seen one or two products online that are cultured marble bases with tile inserts that fit right into the old bathtub rough opening. They were pretty pricey though! I know I could form a base out of concrete and tile over that but I've never done that before and I'm not thrilled with the idea of working with concrete where any leaks could cause serious water damage (the bathroom is on the second floor). Are there other options out there?
Thanks for any input and advice.
