my buddy who does construction gave me a idea last night ...
build a wood pond (box) out of plywood with 2x4 framing, water seal it, silicone the seams ... then staple a pond/roof liner over that, put a little silicone over the staples ... then tile over that using that mesh backed tile.
Might be to much I dont know ... maybe just the sealer over the wood, silicone the seams and then tile over that ... not using the pond/roof liner
