In my master bathroom, I am creating a "water closet": a private space for the toilet. It is 6'6" x 3'6" and similar to a stall in a public bathroom. It has full walls, a full-height door, and a ceiling. It has its own light fixture, switch, and exhaust fan, but no sink.
IRC Chapter 39 specifies electrical outlet requirements for bathrooms but it's not clear whether this water closet counts as a separate room and requires its own outlet(s). I know that if I put in an outlet, it needs to be GFCI and on a different circuit than the light & fan. I am in the United States. My local codes defer to IRC.
Do I need to put an outlet in the water closet?
