This concrete shower is made of 7 panels that are roughly 1/2" thick. The panels are colored all the way through and yes, this is CONCRETE! The wood grain bench, soap dish and curb in the wood grain are also concrete. With zero grout, this is as low maintenance as you get! The water beads right off, simply wipe it down and spray with sealer once every 6 months. These panels are custom made and we can do ANY color or combination of. This is a whole new art form and we are having a ball with it!
