hello! The newbie here. Installing the fireclay sink for the first time. This thing is heavy. What support is required for such a heavy sink? My plan is to use the plywood platform as the platform for the sink. It will stand on two support ledges made out of plywood and screwed to the front and side walls of the cabinet. The cabinet doesn’t have back wall and stands away from the wall. Would this construction provide adequate support for the sink?
