What Is a Jack & Jill Bathroom?


A Jack and Jill bathroom is a full bathroom situated between two bedrooms and is accessible from each room via separate doors. These bathrooms serve homes for families, allowing semi-private access from the bedrooms. Placing the toilet area in a separate cubicle accessed by an additional door within the bathroom extends the use of the Jack and Jill bathroom.

Access to a Jack and Jill Bathroom

  • A Jack and Jill bathroom has two doors and two light switches, each servicing the bedrooms on either side of the bathroom. Both doors have locks to ensure privacy when the bathroom is in use.


  • The ideal Jack and Jill bathroom features two sinks, two medicine cabinets and two storage spaces underneath the vanity. Typically a mirror covers the entire wall over the countertop and services both vanity areas. Optionally, a Jack and Jill bathroom could feature separate framed mirrors above the vanities.


  • Optimally, a fluorescent light fixture spans the ceiling of the Jack and Jill bathroom. Two ceiling lights, two high-hats or two sets of Hollywood-style lights surround the mirrors. Having adequate lighting on both sides of the vanity area individually is important. One long overhead fixture may suffice, in which case one light switch should be placed adjacent to each door. With more lights used, designated light switches should be placed adjacent to the individual doors and areas they serve.

Toilet Area

  • A half-wall on the side of the toilet area provides privacy if a separate toilet room cannot fit within the space of the Jack and Jill bathroom. A Jack and Jill bathroom with a toilet room will feature a separate light in the enclosed toilet room and a lock on the door.


  • A single bathtub with an overhead shower, or a single shower stall is a component of the Jack and Jill bathroom. Separate towel racks are near the tub/shower. Inside the shower or bath, two sets of shelving hold individual bath supplies.
