Bathroom Tile Floor Squeaks
I doubt that it is the tile assembly itself moving independent of the floor but that would have to be verified.
Bathroom tile floor squeaks. But when you notice that squeak take a few moments to listen to what your floor is saying. The tiles or subfloor are loose. Without the proper amount of silicone the pan will squeak. Answer answer the fact that there is a squeak under the tile suggests that the wood underlayment subfloor is moving to some degree.
These gaps occur as lumber dries and nails pop or at places where the subfloor is not properly. I have some very bad news for you and possibly some good if you have a basement under the room with the squeaks. Screws never pull out so they re a great solution against future squeaks. Squeaky floors are caused by the subfloor pulling away from the joists.
Squeaking is caused by something rubbing often the floor boards rubbing on a nails. When a subfloor is squeaking under tile there are really only two options. Sometimes squeaks are caused where the floor tile meets the shower pan. Normally this is avoided if when the wood subfloor underlayment is installed it is glued and screwed so there isn t any movement or chance for there.
This gap is filled with silicone so the grout doesn t touch the shower pan itself. Squeaks and creaks are a normal part of having hardwood flooring. Finding the squeak in your floor is pretty easy. A squeaky ceramic floor is a particularly difficult problem because you really cannot fix it from the top down and if you don t fix it it will eventually break the grout if not the floor tiles because of the movement of the floor.
Start out by checking your rh levels. You can fix the subfloor from below or pull up a tile or a few to fix the squeak from above. If the squeaking floor is coming from under a carpeted surface it s best to remove the carpet and drive hardened drywall screws next to every nail in the floor. Drive a screw through the subfloor into the joist below and make sure to pull the carpet webbing over the screw head.
Tile floors squeak wherever a gap develops between the subfloor and the supporting joist beneath it. Walk over the carpet until you hear the creaking then mark off this area with string or yarn. You need to screw down the subfloor to the joist. The squeak is caused by the wood subfloor that isn t properly attached to the joist.
