What is a Jack and Jill Bathroom?

Jack and Jill bathroom layout is named after the famous nursery rhyme of children. This is basically a full-sized bathroom that is perfectly sandwiched between two bedrooms and is easily accessible by both the bedrooms. This bathroom layout boasts at least two doors, just like a bathroom but for two bedrooms instead of just one. There are times when a third door is added that opens to the hallway, but in general, this bathroom layout is meant to be shared between two siblings to save time during daily routine tasks and space.

When it comes to the layout and design of the Jack and Jill bathroom, there are a handful of options because this bathroom can easily be crafted to suit the needs and requirements of every family perfectly and is a really unique addition to any custom-built home.

When designing a Jack and Jill bathroom, you must always consider the space you have to work with. In addition to this, you must also consider what the members of your family require to create an ideal layout as per their needs. While working with your design to build a Jack and Jill bathroom layout, make sure to consider the three common layouts that involve:

  • A full-sized bathroom between two bedrooms with one toilet, one or two sinks, a shower stall, or bathtub
  • A full-sized bathroom with a shower or bathtub and one or two sinks, but with the toilet in a small separate room located in the bathroom
  • A shower/bathtub and toilet are shared between two bedrooms and two sinks in the nooks located out of each bathroom door but in the bedroom itself.


Average Size of a Jack and Jill Bathroom

Determining the average size of Jack and Jill bathroom is the first place to start. On average, the size of Jack and Jill bathrooms ranges from about 110 to 164 square feet. Of course, some bathrooms can be smaller with a minimum size of 40 square feet or larger, upwards of 170 to 210 square feet. The total amount of square footage you have for Jack and Jill bathroom layout will determine the configuration of bathroom components.

Now, if you are confused regarding “How much space do you need for a bathroom,” then the answer totally depends upon what kind of bathroom layout you want! A full-sized Jack and Jill bathroom with a toilet, sink, and bathtub/shower usually requires a minimum of 40 to 45 square feet. A three-quarter bathroom with a toilet, sink, and shower can only be constructed with 36 square feet. And a small half-bath with a toilet and sink only can be built with a minimum of 20 to 30 square feet.

Are there 2 of everything in a Jack and Jill bathroom?

Though Jack and Jill bathrooms are designed to be shared between two or more people, there is not always two of everything when it comes to sink, toilet and shower. It actually depends upon the bathroom layout and how many numbers of sinks, toilets, and showers are present in it.

As you can see in the example of a Jack and Jill bathroom layout from Winslow Custom Homes, there are two sinks but only one tub/shower and toilet. This Jack and Jill bathroom layout is a perfect example of how these bathroom designs work. It is simply 2 bedrooms that share access to one single bathroom.

So, if you plan to build a Jack and Jill bathroom in a larger space of around 170 to 201 square feet, you can install two of everything, but if you have limited space, you can install one of everything as per your needs and requirements. A Jack and Jill bathroom is defined by the 2 rooms that utilize it.

What are the benefits of a Jack and Jill Bathroom?

Are you curious to know the benefits of the Jack and Jill bathroom? If yes, then we’ve got your back. Below stated are the top benefits of having a Jack and Jill bathroom layout at your home!

Cost Saving

Installing Jack and Jill bathroom layout at your home save both space and cost, especially when compared to pairing each bedroom of the house with its own bathroom. Building more bathrooms in your house increases the cost of plumbing, cabinet labor, and electrical. So having one bathroom that can serve multiple people is a great benefit.


Another benefit of the Jack and Jill bathroom is that, despite its multiple users, it offers complete privacy to every user. Placing a bathroom between two bedrooms prevents visitors from seeing the everyday morning clutter of personal spaces. And as both the doors leading to the bedrooms have locks on both sides, all users can enjoy their privacy.

Excellent for Larger Families

Jack and Jill bathroom layouts are excellent for large families because giving children their own bathroom spaces prevents the spillover of their daily need items into other rooms or bathrooms in the house. Some parents built Jack and Jill bathroom in order to teach their children vital values because by using these bathrooms, siblings learn to compromise, share and understand each other’s level of hygiene and cleanliness.

 How do Locks Work for Privacy in Jack and Jill Bathroom?

As Jack and Jill bathroom is shared between two bedrooms, it is, therefore, essential to know how the locks work for privacy. For both the bedrooms and their occupants to have complete individual privacy in both their bedroom and bathroom, there must be a lock on both sets of doors. In addition to this, those doors must be locked on both sides.

So, in order to maintain complete privacy, all the users of Jack and Jill bathroom must develop a habit of locking both the doors when they enter, and similarly, users must develop a habit of unlocking all the doors when they leave in order to prevent locking the other bedroom out of the bath.
