Diamond Wetrooms do a reasonably priced 900x900 wetroom former which is cheap enough, and GRP so no issue with mosaic ( Wedi products can compress when applying point pressure on small mosaic ) and require little in the way of accuracy of the underlying works as you can bond them down into wet adhesive to set them level prior to fixing down firmly with mechanical fixings. 
I’d recommend a 1200mm or 1500mm area if you’re going to all this effort.

 

 

Please may I have more on this - compressing at point pressure on small mosaic. Does it really get bad? We're all quite large and heavy people so pressure applied when standing is considerable. 

Our concept design is to have a flat-floor walk-in shower WITH mosaic (rest of floor is large tiles). Our builder prefers Wedi products, but we found Tough-X which is apparently a GPR. Would this be better for mosaics? Also currently on sale so really tempting. Also not prepared to compromise on mosaics in shower, it's a matter of deep personal preference ?
