If you rent a common room, you’ll likely share a bathroom with one or more housemates. Agree on morning and evening peak times, cleaning duties, and storage space for toiletries. A shower caddy and labeled shelves reduce friction. Expect to compromise a little on timing and cleanliness habits, but overall, as long as everyone is considerate (cleaning hair from the drain, not hogging the bathroom for an hour), sharing a bathroom is manageable.
