There are 2 types, rest room and bathroom. Did you build a new room?

Got me to, as Shintai says there's two rooms. This is really a problem of people calling restrooms bathrooms. Your local store doesn't technically have a bathroom, it's s restroom, but we so often call it a bath room. The Hotel Galactic Devs might want to consider calling it a toilet room instead of a restroom and calling the bathroom showers room or something. They shouldn't have to because they are right, but common speech complicates it.
