A studio apartment is one open room that combines living, sleeping and a kitchenette, with a separate bathroom. A 1RK is one room plus a separate kitchen and a bathroom. Studios are common in newer projects and serviced residences; 1RKs are common in older city buildings.

When 1RK matters
A 1RK suits someone who cooks regularly and wants the kitchen separate from the room they sleep in.
In more detail
Compare on carpet area and total cost, not the label. Two units called studios can be very different in size.
Rental demand for both is usually strongest near offices and colleges.
Common questions
Is a studio the same as a 1RK?
No. A studio has the kitchen in the main room; a 1RK has a separate kitchen.
Is a 1RK smaller than a 1BHK?
Yes: a 1BHK has a separate hall and bedroom; a 1RK has one room.
Can I get a home loan on a studio?
Lenders lend on studios like other homes, subject to their minimum size and project rules.
