we have a bathroom that is poorly located.(opens to dining area, yuk) had it closed off for a few years. We are now remodeling and have decided to use the space to be a pantry for the kitchen. I am now ready to gut the room and move a wall. But what I don't know is what do I do about drains and vents? Is it fine to simply cut and cap?(raised foundation) We are also reroofing so the vents to the roof can be removed completely during the process.
