Home Depot said yes for bathroom to us and 2 yrs later we have problems with the Traffic Master not only in the bathroom but the den and living room with mold (or mildew).  We followed instructions in testing the slab for moisture - taping plastic to floor for a period of time.  No moisture showed up and now the boards are turning black in various places.  The bathroom is the worst.  Cold water in tank & bowl condensate and now we have a black floor!  It is happening at a slower rate in other areas.  Perhaps we are not talking about the same product.  Ours is a snap lock laminate but with real wood laminated on top (1/32" or 1/64") rather tham a plastic picture of wood.

I wouldn't put a toilet down on top of this flooring unless you cut a U shaped channel with some expansion around the bowl part of the U.  The "bowl" part of the U will be towar the sides of the stool base if you can follow my thinking?  But then the problem exists how to anchor the stool down and allow the floor to float which would even probably work but I wouldn't trust it.  Manufacturers say it is okay for bathrooms but I know just by loking at the composition of the material in general it is a sponge!  As far as the tils the only thing you could do in the bathroom is cut it short of the walls and tub and utilize some kind of trim over the top of it.  You could use a 1/4 round or something similar to trim it out and it might look okay but then again maybe not.  If it were my bathroom I wouldn't sink the money into it I would put my money into a nice ceramic tile with heat underneath or something similar instead but then again what the Client wants the Client gets so if you want it that badly go for it, I just don't think I would want the headache that it MAY produce.  Sincerely ~ James Van Raden ~ Paragon Renovations ~ Moorhead, MN
