Floor Of Bathtub Creaks

The four year old tile floor in our bathroom started squeaking during winter after four years and stopped squeaking in summer.
Floor of bathtub creaks. If you re doing a full remodel and can see the bathroom floor framing from the room below you can usually see where the floor moves and squeaks when someone walks on it. The tub does appear to be level so i don t think that s the problem. Oftentimes the squeaks and creaks you hear are caused by the floorboards rubbing against nails or the floorboards. Rarely is this the case.
It doesn t seem to be such an issue when it s full of water and i m sitting down i suppose the weight is more evenly distributed. The tub flange moving against the wall the tub drain plumbing maybe rubbing against the subfloor. Loaded with water the water weights the tub down thus no movement. Using your power drill make a pilot hole through the subfloor then a smaller pilot hole into the finished.
One tile has a hairline crack now. This can potentially weaken the tub and lead to cracks and splits in. The noise is typically from movement. I need to fix it.
A few well placed screws can eliminate the squeak. When you step into the shower the floor flexes and the wood rubs against the screw or nail making a squeaking noise. With no water each footstep in an empty tub loads and unloads the floor of the tub thus the movement. Yeah it sounds as if they removed the structural support.
Squeaking in an acrylic tub when weight is placed on the floor of the tub can be due to the tub flexing or bending. Bigjaylow nj i recently installed a new acrilic tub in my bathroom. Then fill the holes with wood filler. Or if separating floor from subfloor is causing the creak drive two nails at opposite 45 degree angles into joists which you can locate with a stud finder.
I know it s not the floor boards since the rest of the bathroom is silent. Screws will normally do a much better job of holding the. It was about three years old. A lot of times when new construction is nailed or screwed down they have a little give and take which will cause the sound of creaking.
Since the first shower in it i continuously hear a loud creaking as i move my feet all over the base. Driving short screws through the bottom of the subfloor through the bottom of the finished floor can alleviate the noise. Is this from humidity. The grout in an a joining bathroom cracked also after squeaking in winter.
Occasionally if the floor joist are spaced two far apart to properly support the sheeting then floor creaking may occur. The majority of sub flooring issues can be corrected by adding screws in the areas where the creaking is occurring.
