Rooms: Kirsten’s Bathroom by philo from TSR.
A romantic green and white bathroom with a round bathtub. The size (4X5) of this room make it easy to place in many houses.
Nevertheless, this bathroom was built for an En-suite bedroom (Kirsten’s Bedroom) in Hugo’s Mansion which you can download as an empty shell. It’s located on the 2nd floor as shown on the last screenshot.
