Just done 53m of Casalgrande Mineral Chrom in wetroom and bathroom.
Very very textured
New! - Mineral Chrom - Casalgrande Padana
First was a nightmare trying to wash down after grouting. But what I did as I progressed was grout joints and remove excess almost immediately with sponge, being careful not to touch the joints, worked to about 3-4mm away from it.
On 2nd bathroom I got some empty silicon tubes and filled with grout, then using that I filled the joints, and then forced it fully in with grout float, found that it was quick enough 60x30 tiles so not too many joints.
Don't envy you though
