Yea they list it for that. I got it from another place previously for the £29 a bag. then I showed them the price I was getting it at and said I need another 10 bags can they do it for £25 a bag and they said yes as bulk bought.
Our bathroom was 20sqm. I had to use more in places for levelling out/packing things out, and solid bed floor for the complicated design I was working to which increased consumption considerably.
Yea Primer G I used first. Tanking kit was by Everbuild - Aquaseal - on amazon £32 per kit and used 2.
Adhesive wise if you think about it is cheap
Work out the weight you get then work it back in to buying things like pritt stick ha-ha! Pay like 100x more for those.
Well, I figured use the best - minimise chance of tiles failing
I was using heavy natural stone also. 12mm tiles which were a lot heavier than yours are likely to be.
Also it depends on the Trowl size you use. I used a 10mm bed one. You can use smaller like 6mm etc. But I'd take the bag and any coverage quoted with a pinch of salt. This applies to paint, everything...
If you view my album you can see the bathroom. I need to add more images
Just added this one as a before and after from a single view. Little more work needed to finalise but it's close
