Hi,

We just had a Sterling ensemble installed and the bottom of the tub makes creaking noises when someone walks on it. The noises are pretty noticeable. It has been over a week now. Anyway, I come to find out that the installer did not put a small mat underneat the unit that the instructions said was needed to stop squeaking. After a lot of badgering, he is coming back with the plumber to lift the tub enough to get the mat underneath. He expresses doubt however that this will stop the creaking sounds. He is saying it may be a manufacturer defect. I pointed out to him that the instruction manual (which he obviously did not read the first time around) says cement mortar can also be used. He said this is not a good idea because we are on the second floor.

Anybody have any advice/experience? If the tub continues to creak after they put in the mat, what should I do?

Thanks Mike

BOLONEY!! Puddling mortar or cement under a tub or shower base that creaks of flexes when you step on it is called "bedding the base" and is acceptable on any floor. Good luck, Tom

They have also mentioned using foam in a can. Is this a no-no?

I don't know Mike,
I've never used foam since it consists mostly of air bubbles that will compress over time as weight is placed upon it and you'll be back with the same problem.. Sure it's the easiest but is it the best? It's a quick fix and if it were me I'd make them fix it right. Good luck, Tom

Thanks, Tom. I talked to another plumber and he suggested the cement mortar also.

Do NOT use spray foam.

The non-expanding type will merely compress the first time you fill the tub -- And the expanding type will actually damage the tub as it tries to expand.

Regular mortar mix is the best product to use.

Considering the run of bad luck and bad advice this Plumber has given you, it might be in your best interest to buy the mortar mix yourself and have it on hand when they come to finish the job (I have visions of him showing up with Redi-Mix concrete or Thinset).
