A Jack and Jill bathroom layout, named after the children in the famous nursery rhyme, is a full-sized bathroom between two bedrooms accessible from both. This type of bathroom, like an ensuite bathroom, has at least two doors and is intended for two bedrooms rather than just one. The Jack and Jill Bathrooms depicted in this Jack and Jill Bathroom Layout may not be useful in the long run. Because these bathrooms are linked to specific bedrooms and, in some ways, can become landlocked, they can become less useful and efficient over time. You must install at least two doors to allow traffic to create a Jack and Jill bathroom.
