What Is a Jack & Jill Bathroom?

A Jack and Jill bathroom is a full bathroom that is between two bedrooms and accessible from each through two separate doors. These bathrooms are featured in homes catering to families as two siblings can access the bathroom from the privacy of their own 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 that are situated on either side of the bathroom. Both doors have locks to ensure privacy when the bathroom is in use. Both doors must be unlocked when leaving the bathroom to keep the room available for continued use.


The ideal Jack and Jill bathroom features two sinks, two medicine cabinets and two storage spaces underneath the vanity. One mirror covers the entire wall and services both vanity areas. A more decorative Jack and Jill bathroom features two separate framed mirrors above the vanity. Small bathroom mats are in front of each sink.


One florescent light 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, if two mirrors are used, and are sometimes used in the shared bathroom in place of the florescent light. Lighting both sides of the vanity area individually is important. If one light is used, one light switch should be placed adjacent to each door. If two lights are used, designated light switches should be placed adjacent to the individual doors.

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. If the Jack and Jill bathroom has a toilet room, it will also feature a separate light and a lock on the door.


A bathtub with an overhead shower or a shower stall is a component of the Jack and Jill bathroom. Unlike the vanity area, there is only one bath or shower space in the bathroom. Separate towel racks are near the tub/shower. Inside the shower or bath, two sets of shelving are placed to hold individual bath needs. One large bath mat is placed in front of the tub/shower.
