If I get tile from home depot they mentioned about $2 per sq ft for labor and I was wondering if that sounded accurate.

Yes, maybe on the cheap side depending if you are using staggered joints and the layout of the room.

How long are your pieces? More Gowan into woodlook tile than square or rectangular tile (found out myself when we had ours done).

The longer the pieces the "nicer" it'll look but the floor has got to be very level. We had self leveler poured in 2 or 3 rooms out of 8 I think and we were using 48" long tiles.

I think we paid somewhere around 1.80-2.50 sq ft?

Not that long at all Maybe 2ft
