Tub is creaking

a few years ago i had my master bathroom redone. I had the contractor install a kohler drop in soaker tub, which is placed into an alcove with 3 walls and a ceramic tiled in front short wall.
I happened to be there when he was doing the tub, and i watched him place some scraps of cardboard and other debri under the center brace under the middle of the tub. I asked him about it and he said not to worry that it's not necessary to have a wooden support under it. Well it's always, since new been a little creaky as I move around in the tub, lately it's been getting worse and I'd like to fix it.

My issue is that to get under the tub, I'm going to need to get thru the front tile, but i cant find the same exact tile. I suppose I could replace all the tile on that section, it's about 20" high and 60" wide.

My question is... Is there a way to cut into one of the tiles to gain access to underneath the tub? - Do it in such a way that I can reuse the tile? cut along the grout lines?

thanks in advance for any tips

Re: Tub is creaking

You can remove the grout around a tile with a utility knife or and oscillating tools like those made by Dremal, Rockwell, Dewalt or a lot of other manufacturers.You you are careful you may then be able to pry the tile loose. You might consider installing spry foam under the tube.

spray foam would be handy, i could potentially only remove 1 tile to get enough access . Any idea what kind i could use? - it would have to be durable, and able to carry some weight once it's cured.

thanks Jack

I've used http://www.homedepot.com/p/GREAT-STUFF-16-oz-Big-Gap-Filler-Insulating-Foam-Sealant-Quick-Stop-Straw-99053938/207050533

The foam expands and fills in and once cured is pretty solid. For a tube it will probably take several cans.

Re: Tub is creaking

You don't want to use foam. The correct procedure typically done during tub install is setting the tub in a small pile of mortar, it then hardens and creates a solid base. This is mainly used when NOT installing solid steel, cast iron etc... because they don't flex. Acrylic and molded tubs normally have a bit of flex to them.

The other issue could be the tub legs are rubbing on the sub floor, easily fixed by using SHIMS, not card board or foam.

Keep in mind foam is the wrong product to use, its not hard enough and won't actually fix anything, you will continue to hear the noise if you use foam. IF its not the tub, then it could be the subfloor. A simple nail that missed the joised and is rubbing can make a sqeeking noise.

Take off the tile like others have suggested, mix up a buck of mortar and place under the tub bowl.

Well I've had foam under my one piece shower for 30 years and it is still solid.

Re: Tub is creaking

what pcride said is correct. If you use expanding foam it could lift the tub, the correct way is to place a shovel full of soft mortar in the centre of the hole and then install the tub and stand inside to seat the tub. then install screws on the tile apron into the 2x 4 surrounding the tub. If some one screwed this up remove the tub and redo over.
