I am currently remodeling my 2nd story bathroom, and ran into a HVAC problem. I currently have a pedestal sink in the bathroom and want to install a larger sink/cabinet combo. However the furnace vent comes out of the wall half way under the current sink, so I need to relocate it. I canít go out into the floor because the sink and tub drain run is right there. Iím thinking the only option is to relocate it up on the wall. Would this be a bad idea? I know hot air rises, but the bathroom is getting gutted and fully insulated. Does anyone have any suggestions?
