A 2-bedroom apartment with a single shared bathroom is a layout defined by a constraint: two private spaces queue for one wet space. Where you put that single bath, and how equidistant you can keep it from both bedrooms, is the most consequential decision in the plan.
How this generator works
Seven templates handle 2BR/1BA: corridor-h, corridor-v, side, open-row, lshape, central-bath, and back-to-back. The central-bath template specifically puts the bathroom between the two bedrooms with adjacency to both — this is the closest a single-bath plan gets to feeling like two bedrooms have equal access. The lshape and back-to-back variants sacrifice equidistance for envelope efficiency. The bathroom area is capped at 7 m² because a single shared bath that grows beyond that is unusual in real construction; the m² is better spent on a slightly larger second bedroom.
Design principles for 2BR/1BA
Master bedroom ranges 10–13 m², second bedroom 8–11 m². The 2 m² delta matters because it lets the second bedroom function as a child's room or a small home office without feeling like a closet. The bathroom occupies 4–7 m² — anything below 4 makes a tub-and-vanity layout impractical, and above 7 wastes plumbing m² that could go elsewhere. Living room area lives in the 16–28 m² band; kitchens are usually separate at this size class because open kitchens in 2BR plans push too much heat and noise into the shared living area.
When 2BR/1BA works best
Roommates splitting rent, small families with one child, and rental-grade investment units all favour this layout. It is the most cost-efficient family configuration: one bathroom, two private rooms, lower plumbing cost than 2BR/2BA. It becomes uncomfortable when both bedrooms are occupied by adults with overlapping schedules — morning routines collide.
Configuration tips
Pick central-bath template via the seed slider when both occupants need equal bathroom access. Pick corridor-h/v if one bedroom is clearly the master and the other is for guests or short-term occupancy — the bath naturally drifts closer to the master. Open kitchen is rare at this size because acoustic isolation matters more in 2BR than in 1BR. A balcony off the living room is the most common addition; a balcony off a bedroom is the rarer luxury option.
Frequently asked questions
Where is the bathroom placed in a 2BR/1BA layout?+
It depends on the template. The central-bath template puts the bathroom equidistant between the two bedrooms; corridor-h and corridor-v place it along the corridor; lshape and back-to-back accept slightly unequal access in exchange for envelope efficiency.
Why is the bathroom area capped at 7 m²?+
A single shared bathroom rarely benefits from being larger than 7 m² in real construction — beyond that the area is better spent on a slightly larger second bedroom, or on adding a second bath altogether (use the 2BR/2BA generator).
How do I choose between 2BR/1BA and 2BR/2BA?+
2BR/1BA is the cost-conscious choice: lower plumbing cost, smaller envelope, suitable when the two bedrooms are not occupied by adults with overlapping schedules. 2BR/2BA adds 8–12 m² of plumbing area and is justified when both bedrooms have adult occupants or when you frequently host guests.
Are open kitchens common in 2BR layouts?+
Less common than in 1BR. Acoustic isolation matters more in 2BR because there are more occupants and overlapping use of the public zone. Open kitchen at 80+ m² is workable; below that, separate kitchen is usually preferred.
