Mosiacs on a bathroom floor!!!!!!!

[marc1106]

am quoting on abathroom refit client wants mosiacs on the floor!
sub floor is t&g chip which we are ripping out! gonna do 18mm wbp ply then 6mm hardibacker(or equivelent) gonna have to do the whole floor as clients having a freestanding rolltop bath! tiled many floors but NEVER in mosiacs is there anything i should be aware of!
thanks in advance marc1106.:45:

Hope they have a maid.

I hope she slips on the wet floor, cracks her head open on the bath edge and stains the grout with her blood!

(I'm really not bitter:incazzato🙂

A lot of joints there doug......plenty moisture ingression........i would deffo go for the hardi marc...but use 22m ply and nog out the joists every 300mm as well...then screw down tot he joists and noggins...flexi spf rapid for sticking the hardi down and to tile with a white spf..unless grey grout then grey adshesive..

The hardi just adds that litte bit extra strength..

oh yes, it's a mosaic floor! lost the thread title halfway thro' (boys distracted me!) apologies!
