Hi all

I am thinking of tiling the walls of an upstairs bathroom with ceramic
tiles, from floor to ceiling. The tiles that I have in mind are 8mm
thick, and hence weigh about 20 kg/m2. I'm wondering if I might run
into issues with:

(i) The tiles being too heavy for the walls. For example, could the
tiles pull away from the wall, or could the wall buckle under the
weight of tiles? About two-thirds of the wall-area comprises Paramount
partitions (i.e. a cardboard honeycomb core sandwiched between ~11mm
plasterboard). The rest of the wall area is the external wall of the
house (i.e. plasterboard with dot-and-dab).

(ii) Floor loading. The wall area is about 20 m2, hence there would be
400 kg of tiles. Presumably much of this weight would bear on the
timber floor joists underneath the bathroom.

Any advice appreciated!

thanks,

Julian
