The recessed area for the tub location should have walls framed with 2x4 or steel studs, according to the rough opening dimensions provided by your tub’s manufactur- er. The rough-in framing must be plumb and square. In general, 2x4 wall studs spaced on 16-in. will suffice. In our particular situation, a vent pipe from a first-floor bathroom that routed up through one of the surrounding walls complicated the framing in our upstairs bathroom. The old vent stack was larger than the 3-1/2-in. wall studs, so we had to shim out the rear wall studs to enclose the pipe. You might face similar obstacles that require you to take such measures. Another note about framing the surround: Plan in advance if you want to include any recessed nooks, shelves or other acces- sories, and frame them according- ly. Even bolt-on accessories will require solid between-the-stud framing to mount them, so go ahead and install the 2x blocking while the walls are open. Once the wall framing is com- plete, horizontal stringers should be installed across the studs to support the edge of the tub deck.
