My mother had her bathroom remodeled from 60s style thick half wall tiles to drywall, but the drywall is thinner than the now removed tile wall. The problem I noticed is that the hvac supply vent sits away from the drywall. And the hvac duct is fixed inside the wall. I am wondering if anyone else has run into this type issue. I’m almost thinking of framing the supply vent with wood to make it look cleaner. Any suggestions?
