The wall and shower floor and curtain thing - That resin bamboo panel was made by a company called 3Form and the bamboo's actually pressed inside a panel made from acrylic or polyester. 3Form's panels hold up well when used like this. Here's their website: http://www.3-form.com/ RE cleaning the shower floor - Many cedar and wood application like this, are removable. Meaning the wood usually sits on a grate or a raised surface below, but over the drain. Therefore the wood could be picked up. Remember the drain has to be accessible in some way if need be, so there has to be a way for it be removed. the wood floor is constructed like a deck - that is, it sits above the shower floor and the boards are spaced apart so that the water flows through to the drain below. The entire floor can be picked up (in two pieces) to access the drain and to clean the shower.
