Check the actual stud to stud dimension on the rough in, If you only need two inches or less, you might consider notching the studs 1 inch on either end.

The only thing i would caution, is do not make the mistake I found in the house I am currently doing a rehab on. The bathroom here is 56 inchs stud to stud and they removed a stud to install a 60 inch cast iron tub. The right hand end of the tub was actually pressing against the exterior wall sheeting.

They then installed a 2 inch scab in place of the stud and installed lathe boards curved to form a recess in the wall for the end radius of the tub. In thirty years of plumbing i have never encountered such a mess.

If that were not problamatic enough, they had the faucett/shower mixer on the left hand end of the tub, and the drain on the right hand end. I could just imagine trying to stretch out and relax in that tub with the drain stopper control handle digging into your back, but then i guess one could sit the other way and lean back on the faucett spout.

Needless to say, i had to rework the framing, then special order a 54 inch tub, not to mention I had to remove all the existing waste pipe for the entire bathroom and redo it for numerous problems. The most notable problem was that the tub drain was now directly over the house sill plate, so they attached an automotive radiator hose from the tub drain to form around the sill and attach to a trap in the basement.

Oh,,did i mention that there was a 2 inch slope in the floor on the 56 inch run? Now that is amazing, more than a 1/4in per foot slope on the floor, but the drain pipes were all level.

Given that i found 4 empty quart bottles inside the walls, i must presume that Jack Daniels was the original architect on this project.
