Grout Steam room grout options - Tile Advice

[wayne]

Im tiling a bathroom this week and I've now been informed that it's going to be a steam shower fully enclosed. It's all waterproofed etc but I'm in 2 minds about grout. I thought it would have to be epoxy but keracoll said I can use their fugabella grout. Anyone got any thoughts on this or if ultracolor plus would also work

Any steam in my rooms and it's automatically epoxy.
I've heard the argument that cement based is ok, but why do it when there's the option of epoxy?!
Certainly, with no mosaic and large format you might be ok, but I like to sleep without waking up worrying about jobs.
