I plan to build a tiled steam room in an extension. The only thing I
am not sure about is how to construct the seat. I want one that is
nicely curved to be comfortable.

It will be a rectangular room with a straight seat along one side, so
I only have curves to worry about in one dimension.

I am thinking of a wooden frame over which strips of tile backer are
secured, sealed together and then tiled with mosaic tiles.

Has anyone done this before who can give any advice?
