How should I attach glass panes for use as shower walls in place of tile?
I want to build an all glass shower, including glass panel back walls (see picture at top of page here: http://grayglassblog.com/backpainted-glass-shower-walls/) I am having great difficulty finding how they should be attached to the wall and what material should be behind them.
For example, should drywall vs. concrete board behind? Should they attach simply with silicone or would thin-set mortar provide better adhesion? I tend to doubt mortar, as glass is flat and does not have the ridges like the back of tile does.
The closest I've come to an answer is how this is used in kitchen back-splashes, where they say having j-channel around the outside and some silicone on the back, spaced in circles is more than adequate. This seems to also be the case with thick plastic shower panels, just not sure if the same silicone 'circles' technique will be effective.
It sounds like I want 'colored' not 'painted' glass in this case.
