Tiling my bathroom floor, some questions.

funktional · 03-07-2008, 11:28 AM

Looking to install 6"x6" ceramic tile throughout our 10'x10' second floor bathroom. Currently there is VCT glued down to 1/8" plywood which is nailed on top of 3/4" plywood. Unfortunately I don't know the spacing between the floor joists but the house is only 8 years old, don't know if that would at least give some idea. The floor seems quite solid, have not experienced any kind of bounce or sag. Since the tiles are glued down to the 1/8" plywood what kind of prep work am I looking at in order to be able to install new ceramic tile after tearing up the VCT? I would prefer not to have to rip up the 1/8" plywood as it is currently installed underneath our vanity as well. And what do you typically do in a bathroom where there is a vanity installed? Should I remove it and tile underneath, then replace the vanity? If I tile up to the edge of the vanity, what if I decide to replace the vanity down the road with something that doesn't have the same exact footprint?
Any information and help would be appreciated.
Thanks,
RJ

after you tearing off the plastic tiles, you need some sort of water proofing membrane....tiling directly on plywood is not a good idea in wet place.

if you don't mind spending a little bit more... buy those orange plastic membrane somthing call didre (don't remember the name).... that is the best ...

you should remove at least the toilet before tiling....

you don't need to remove the bath tub as this is way too much

you may or may not need to remove the sink depends on what sink style you are using (for predestal, I would remove it as it is very easy to remove)
for those wood thing... I will keep it there... and true if you are going to change in the future, you either have to buy the exact same style or a bigger model though....

what else....

can't think of any for now....

RJ, you wouldn't want to allow the 1/8" ply to remain. After removing it you should add cement board. It is important to first know the joist spacing due to the potential for deflection between the joists.

If you intend to replace the cabinet/vanity anytime soon then maybe the thing to do is remove it and tile under it. It is very likely you won't match the footprint exactly with a new cabinet later.

You do not necessarily need a waterproofing membrane for a floor in a bathroom.
