I do know a man who can tile an average bathroom in a day for sure! i have worked with him before as a labourer! i was the one with the sore back and all believe me!!!
even on floors if he hadn't 20mtrs down by 12 pm he'd be cross,lol.
I seen him throw down 70mts one day and it was damn well done.
I prefer to take a more relaxed approach !
I found this hardly believe, sorry mate.
I believe those areas in one day, but I definetly don't believe they were done damn well.
If the surface is really good,
if I have a labourer,
if the tiles are at least 600X600 mm,
if there is very little cutting,
if I work at least 10 hours a day, than I can lay down 40-50 sqm on floor with lips no bigger than 0.5 mm and 1.5-2 mm joints between the tiles.
I don't acept bigger lips or joints.
Bathroom - one day again - with perfect surface, no corners for mitring and very little cuttings - only then it's possible
