Hi! I just underwent a major remodeling in my bathroom that included demolition down to the studs. A few months after completing the project I noticed that the bathtub is slightly “unlevel.” This is noticeable on the outer surface of the tub, by the faucet side and it slopes the slightest bit to the outside, where water pools and puddles along the floor. I noticed the problem when the paint on the wall next to the tub bubbled(see photos). Removed the bubbled paint and behind it was wet sheetrock. The contractor claimed it is because the shower is hitting it directly (he said without seeing it) but that doesn’t make sense. The contractor has been blaming the age of the house and how the house is uneven but my first question is if the bathroom was rebuilt from the studs up, wouldn’t they have been able to install the tub correctly regardless of the age of the house?
My second question is what options do I have? Is the contractor required to fix this? And advice or direction is appreciated.
