The tiles in question are not rectified and thus have a crown.

Can you elaborate?

Hi Lisa,

If I am getting what you are putting down (pun intended). I would go with the standard subway pattern. It should help alleviate the discrepancies of your long tile. Lots of 24" tile tend to cup, there isn't a lot a tile layer can do about it either.

30 70 brick pattern or 50 50 brick.

Most 24" tiles are bowed or crowned nut not all of them. If they are crowned and you dont want to return them. You can install them in a brick (staggered) pattern or in a block or square pattern. In the square pattern the crowns will match up so you wont notice it. However in the brick pattern you will notice the crown or hump between tiles and there is nothing a tile setter can do to avoid this. Of course how noticable it will be depends on how crowned they are. Dry lay the pattern out on a flat floor and you'll see how bad it is and if you can live with it. Porcelean tiles are less prone to the crown vs ceramic tiles.

Thank you for the replies so far.

The tiles were laid in a 50/50 split brick pattern and the floor is completely uneven. You can see "hills and valleys." There is significant lippage between the tiles. The edge of some tiles are visible and the grout lines vary between 3mm and less.

In speaking with tile showroom employees, they have all said that a 70/30 split or stacked pattern is recommended as the 50/50 split brick pattern aligns the highest point of the tile with the lowest point and thus causes lippage.

I was just curious to know what other contractors had to say.
