There are two different layouts of transition sleepers. One has two combo restroom/showers on the upper level and one downstairs. The other has an extra roomette at the end of the car where one of them would be, and the other is toilet-only with no shower, but, as I recall, there is a second downstairs shower in that config. There is no way to know in advance which configuration you will have.
(Actually, there is a third configuration, which was done during an overhaul at Beech Grove, taking components from a wrecked car to create somewhat of a hybrid configuration)
