21 Jack and Jill Bathroom Ideas and Layouts (2)

A Jack and Jill bathroom is an old-fashioned term for a shared bathroom that has two doors that open up to two separate rooms. Often shared by siblings, Jack and Jill bathrooms are space-saving solutions that can be adapted for other uses.

This may include anything from two guest rooms that share a bathroom, or single bedrooms that share the bathroom with a study, den, exercise room, or home office on the other side. A Jack and Jill bathroom may or may not have a double sink vanity to make sharing more comfortable, but will otherwise include a shared shower, bathtub, and toilet.

Check out these Jack and Jill bathrooms in a range of layouts and styles for inspiration.

What Is a Jack and Jill Bathroom?

A Jack and Jill bathroom is a shared bathroom that connects two bedrooms, often for children. They are usually only accessible from the bedrooms, and may have double sinks or vanities.

Add Personal Touches

Not all Jack and Jill bathrooms feature two separate vanities, but a bit of clever styling can help make the most of this shared space.
"If you have a double vanity, I always recommend giving each kid their own bath mat and step stool, as it can help them 'mark their territory,'" says designer Georgia Zikas."If you only have one sink, then give each kid their own toothbrush cup or their own piece of art to hang so they feel the room is uniquely theirs."

Choose Two of Everything

When designing a Jack and Jill bathroom from scratch, opt for two of everything.

Light With Sconces

Sconces are an excellent choice for a Jack and Jill bathroom, particularly when a double vanity is used.
"In this situation, we place a single sconce on each outer side of the sinks, and one double sconce in the middle of the two sinks," says interior designer Jennifer Barron. "This gives a very cohesive look."

Embrace Symmetry

Use a symmetrical layout to unify the space.
"The bestJackandJillbathrooms have a strong sense of symmetry," says interior designer Christina Kim. "Sometimes thearchitecture doesn't allow for this however,andyou have to trick the eye a bit. Placing one long mirror above both vanities goes a long way in balancing an asymmetrical layout."

Tweak the Layout

Interior designer Nicole Michael offers a twist on the traditional Jack and Jill layout.
"Each of the bedrooms has an en suite bathroom with a sinkanda toilet, but then those two rooms connect to a common shower room," she suggests. "This is especially if you have kids of the opposite sex: It gives them privacy but also a great opportunity to learn how to share a space. You also save on construction by not duplicating a tub or shower."
