Tile, adhesive and grout

[yul]

Hi great site site very informative for non tilers like me. Tiling around the bath up to ceiling with shower over bath.What i need to know is how to work out weight of everything per sq meter. My tiles work out at 16.2kg sq meter what extra am i looking at with addy and grout as im tiling onto plaster and need not to be over 20kg.

I would allow around 3kg for adhesive and grout, IMO you are fine with that tile weight.
