hi amcrozier,the only thing icould add to the already very decent tips,select a couple of tiles out of each box and check the sizeing...this is important for any tiling,however the smaller the joint the more importance....the other thing of note was that you wanted the client to level the floor...................YIKES SCAREY......levelling the floor yourself makes life easier later and you get to charge for it to.........good luck with the job ................chris
