I have an old boxed-in corner shower. The glass screen has three panels which are all very hazy. I can't afford to replace it right now. I was thinking of putting mosaics (big pictures – not little squares) on a couple of the panels to distract from how bad the shower looks. There is one panel in particular that measures 21 cm wide and 159 cm long. I will put the mosaic on the outside (away from the water).
Is the shower screen glass itself a suitable backing and if so, does it need to be prepared in some way? I plan to use glass for the tiles (cut to shape for the picture) and clear adhesive. Not sure though if it will stick and if just adhering direct to the shower screen will be ok. Also, what can I use as grout between the glass pieces? I have only ever done glass mosaics on pottery with coloured grout. Do I need to grout? I would need to use something clear – can I use clear silicon? Thanks.
