Shower pan
I just had a old shower removed in which the floor of it squeaked really bad when moving around in it. Now, I have a tile shower with a shower pan at the bottom. I watched it be installed and it is snug to the floor. However, after about a week it is now squeaking around the drain just like the old shower. How can I get this fixed??

What kind of pan did you have installed?

Wood floor and no mortar under the pan? Hole in floor just big enough for the drain pipe to fit thru?

I don't think it was morterd. Under the house, the drain pipe is sitting tightly in a cut out section of a floor joist.

How much floor joist was cut out Without anything under it, it will move a little and the noise is likely where the pipe rubs against the wood.
Can you post a photo or two from below?

When installing a fiberglass pan, I always put a number of dollops of mortar around the base before dropping the pan down. When it sets, it forms a solid base in cotact with the pan to minimize movement. What you are probably hearing is that movement against the drain pipe or the pan rubbing against the subfloor.

I think my big concern is the cut floor joist. Can you post a pic of the area?

Yes, I can. From looking at the pan from underneath the house it looks perfectly snug with the floor. I'll post some pics, though.

Ok, so I got under my house to take pictures and noticed I had a leak. It was coming from the shower water supply pipes at the top near the shower head. The subfloor appeared to be pretty wet. The leak was repaired and now a week later the creaking noise has decreased by at least 75%. Could that have been the bulk of the problem?
