I am wondering if there are any concerns reguarding installing large floor tiles in an upstairs bathroom. There are a couple places where ther floor creaks and i am planning on fixing these. Is there a weight issue? I am fairly handy and understand the basics of laying tile. The subfloor is waferboard. I will need to lay down the (cannot remember the name at the moment :) ???? board on top of the wafer board and attach. Well i have run out of time but if anyone can answer my questions and/or point me to a good website I will appreciate it.
