I removed my bathroom vanity and found some pipes. What might they be?
Drain and dry vent, most likely. Rip some drywall you won't have to do a fussy repair job on because it will be hidden behind the new vanity if you are overly curious and want more info.
You'd put a vanity on them the same way the vanity you took off them was - they are running in the &quot;toe kick space&quot; between the floor of the cabinet and the floor of the room.
