A Jack and Jill bathroom is a bathroom space that is shared between two bedrooms, where both bedrooms have their own doors leading into the space. This type of shared bathroom is popular in some kinds of homes. These bathrooms allow for use by more than one person, and are accessible from more than one room.
Lots of common Jack and Jill bathroom designs feature a double bathroom vanity. This kind of bathroom vanity includes two sinks, which means that more than one person can use the sink area at the same time. Many of these bathrooms are set up as “couple’s bathrooms” with separate storage spaces for each member of the couple, as well as separate towel racks for monogrammed or color coded towels.
Although this type of bathroom can be convenient, especially for larger families, there are some potential problems with having a bathroom that includes double access. Adequate locking and privacy can be an issue for some. In addition, if a home is split up into rental spaces, or if there are changes in who is using various bedrooms, having a shared bathroom can become an issue, especially if appropriate locks and latches are not in place.
Real estate professionals use the term “Jack and Jill bathroom” to refer to these kinds of shared bathrooms. Some argue that these bathrooms are effective in opening up a residential space. Others would say that privacy issues make this design less desirable. A lot of the appeal depends on how a home is structured.
In older houses, where bedrooms are often clustered, creating a Jack and Jill bathroom with a double sink can be practical. The additional of a double bathroom vanity does not usually constitute a large plumbing expense, since the two sinks can utilize a lot of the same plumbing hardware and connection. The issue is in designing the right double pathway to the bathroom, and ensuring access. Some home designers and planners recognize that over time, families might decide not to use one of the double access doors, and instead seal the door off to provide a wall that gives more privacy to the bathroom as well as the adjoining bedroom. Those designing and using a home with this type of bathroom have to decide if the setup stands on its own merits.
