The two bedrooms in the Baths Superintendent's flat are the only rooms at first floor level. The plan clearly shows the three ‘lanterns’ in the roofs allowing daylight into the hot rooms (arrowed on the plan), the cooling-room (below it on the plan), and the plunge pool room.
The hot rooms roof and lantern can still be seen from the rear of the building in the photo below, which was taken facing the direction of the arrows.
