Hi, I want to create a shower cubicle similar to the below. 2 walls of the cubicle will be tiled (porcelain or marble) and 2 will be glass panels. The shower tray will be 900*1600mm. I plan to install the shower tray onto the joists (1st floor suspended timber floor) into the corner and level the floor and then fix cement board to the walls and tile onto these and onto the shower tray. This means the cement board and the wall tiles will overhang the shower tray. I will also make the glass panels overhang the shower tray slightly and mastic round the edges.
While researching I thought I'd need to tank the shower cubicle on the floor and all the way up the walls. However, I spotted this review

"sorry but i just don’t get it. if you use the appropriate adhesives , grouts and sealants then theres absolutely no need for this lets be honest if water is getting behind your tiles , grout or sealant then it’s too late. no amount of ‘rubberised paint ‘ is going to save it. i’ve fitted dozens of shower cubicles over the years never used this before and never had a problem. "
Also I found a lot of people say it was only necessary to tank 12" up the wall ie. most of the wall near the shower would not be tanked. Since I'll have decent overhangs all around the tray I'm not sure I need to tank at all.
does anyone have experience of this?
