Hey guys, The master bathroom in the house I'm renovating has an ugly drop tile ceiling that I want to replace with moisture-resistant drywall. The bathroom in question is directly underneath the second-floor bathroom, which apparently has been altered from its original set-up at some point. The second floor plumbing extends down below the floor joists, which means I can't screw my drywall directly into the joists. This is why the previous owner chose to install drop tiles. I'm trying to figure out the best way to build a ceiling frame that will support the drywall ceiling in the first floor bathroom. Will a frame built from 2X4s and tied into the room's walls support the ceiling drywall? Any help you can provide will be much appreciated!
