bathrub/ floor trouble

We have a corner jacuzzi tub and lanoleum flooring. We have tried using caulk for the floor/tub seam but it never holds, the tub must rise and fall with water or something because the caulk ends up on the tub or on the floor over time with a gap in between. We tried one of those sticky seams but since the tub is large and has two rounded corners half was on the tub (in the front) and the sides ended up stuck to the floor. Does anyone have any recommendations for a caulk that will stretch with the tub and not peal off, or should we try a flexible quarter round and attach it to the floor so it doesn't move with the tub?

I'd stop with the caulking and install a stick on rubber/vinyl base molding made especially for bathrooms. It will cover the gap since it's flexible. Available everywhere.

BTW, why do you have laminate in your bathroom?

Sorry, lanoleum, not laminate. :) We tried one of those stick on mouldings and it slid down the side of the tub over time.

question, is there a reason that the tub moves so much?

How can it slide if it's sitting and resting on the floor? Who installed it?

I have mouldings like these in some rentals that haven't moved, not even 1/16", in 25 years - and these rentals are sitting on earthquake faults.

We're not sure, we are assuming that it must rise and fall as it is heavier when it fills and lighter when it is not? It is a triangular shaped, prefabricated jacuzzi tub. It doesn't slide side to side, but for whatever reason whatever type of caulk we have tried will eventually slide down so it is no longer attached to the tub, or will only be attached to the tub and not the floor...thus the assumption that it must rise and fall.

Errr... that's gotta make you mad. I would look into where the deflection is occurring and fix it. two places to try, a Jacuzzi store and the other a Boating/Marine store. both have to deal with extreme environments.

Re: bathrub/ floor trouble

My bet is that when the tub was installed it was not bedded in mortar to support the bottom of the tub fully, hence the extreme amounts of flex you are seeing.

A retrofit fix will be tough, but not impossible. Basically what you need to do is gain access to the underside of the tub and force mortar under the bottom of it to take up any gap. When cured, the mortar should prevent the tub from flexing as much.

Another option would be to switch to a beutyl caulk that stays extremely pliable that can handle the stretching and pulling.
