It's almost identical to a VGF studio except the toilet is in the room with the walk in shower and the sink is in the section with the tub/shower combo. There is a pocket door between the two sections. So yes, 2 showers, 1 toilet and 1 sink.
Yes, some door(s) in between, could just be one. Or it could be none if no one else is in the wash room and you didn't have to close that slider between the two. Most studios have a set up that has a door between the toilet room and the sink so if you didn't have to close the slider it actually has you ahead of many other studios on cleanliness. OKW, BLT and PVB are the exceptions at WDW? VGF - if you don't have to close the dividing slider. But BWV, BCV, VWL, SSR, AKV and CCV all have doors I think.
