Define what “private” means in this home
Before choosing a premium, describe the access rather than relying on the bathroom label alone.
- Is it a full bath or a half bath?
- Is it attached to the bedroom or reached through shared space?
- Does one room have exclusive use?
- Will guests or other roommates use it regularly?
- Does the arrangement add meaningful privacy or convenience beyond the bedroom itself?
Use an access framework, not a universal percentage
Bathroom value depends on the specific arrangement. These scenarios help the group compare assumptions without prescribing one standard amount:
- Exclusive attached full bath: the strongest privacy and convenience case.
- Exclusive half bath: private access, but without bathing or shower use.
- Full bath with occasional guest use: still useful, but not fully exclusive.
- Bathroom used by regular household traffic: closer to a shared bathroom than a private feature.
Work through the discussion before entering a premium
Imagine that bedroom size is already handled by the base split. Room A also has an attached full bath, but guests use it occasionally. The group can record the bath as a separate feature, note that access is not completely exclusive, and choose a visible premium that reflects that assumption. If guest or household use becomes regular, the group can reduce or remove the premium rather than changing the bedroom-size rule.
Keep related questions separate
Bedroom area belongs in the room-size baseline. Bathroom access can be a separate premium. Cleaning responsibility may be worth discussing, but it does not create an automatic rent adjustment. Utilities and other shared costs can follow their own household rule.
