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. 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.

you have 3 options
1) have the plumber fix it.
2) pay a different plumber to fix it
3) fix it yourself.

The water should not get on the edge of the tub. A shower curtain should prevent the water from getting there. A shower door would prevent the water from running down the face of the tub. I get in the shower, turn the water on, wet my hand and slide it down the edge of the shower curtain and stick the curtain to the wall closest to the shower head. This takes two seconds while the water temperature stabilizes. Keep in mind...even if the edge was dead level, the water doesn't know which way to go. If you have people in the house that can't or won't do this, then take the tub out, build another wall and make a walk in shower. Find another contractor that knows how to fix framing if you go that route.
