I have done 15m of 600 x 300mm in a day before, grouted next day. I dot and dabbed all the walls beforehand so they were perfect. I have also taken 3 or more days doing the same amount. standard walls A general rule is that you wont get it done in a day, or you will but it'll look a bit rough. Believe me, I pretty much find fault with 90% of tilers work that I see, in fact I can't remember seeing a tiling job recently that was done well.
