Not that I’ve been working on it for that long. Cutting and laying the tile (a relatively simple task) only took 3 days; acquiring the tile and investing the time presents the greater challenge.
My advice to would-be tilers is only this: buy as much extra tile as you can afford. It pains me to think of the cost of all the tiles I broke in cutting, but a worse fate would have been to run out of tiles before the mortar has a chance to dry. Out of 3 cases of tile, only 3 tiles remain unused.
It also helps to have a second bathroom. God, how I wish we had a second bathroom (tiling, grouting and sealing takes about 3 days to cure; at no point during that time can the bathroom be used for anything). If you are unlucky enough to have just one bathroom, the restrooms at Kohl’s are very tidy.
