Heavy granite wall tiles on plasterboard wall

[Stevie1963]

Hi Guys. I have bought some 300x300mm granite tiles with the intention to tile my shower cubical. When I collected them I was amazed at the weight of them (10mm thick) and queried the suitability with the salesman but he assured me they are suitable for both wall and loor and that the new plasterboard wall would support the weight.
The wall is a new stud partition with timber 600mm centers using 12mm plaster board and plastered over.
Can anyone advise/assure me that this will be sufficient to take the weight of the tiles before I start ?
Thanks in advance for any sensible responses.

I have tiled 12mm quartz 600x300 onto plasterboard with no problems, see pictures

Hi,
Absolutely. Screw the plasterboard to the studs a maximum of 12" (300mm) apart and waterproof (tank) the shower enclosure prior to tiling. Hope this helps? Ian @ JRHConstruction.

Thank you both for your replies. That has given me the confidence to do the job now. I must admit I had never heard of "Tanking" before but once I read up on it I bought a kit today and started to install it this evening.
I'll post some pictures once finished.

Shouldn't have had the walls skimmed over, they are able to hold more weight without being plastered

Looks a good job

Un-skimmed plasterboard has a tile + adhesive weight limit of 32kg per square metre. Most tanking kits also have a circa 30kg limit.

If the tiles are heavy you'd be better of with boards such Marmox/Wedi/PCS/ etc. They have very high weight limits and are waterproof so don't need tanking.
