You know the all in one bathroom?

@mw1525 You are correct on the number of tiles. But you're wrong about there not being a sink. Don't ask me where it is, because logically, there is no room. But if you send your sim in there and listen, after a few moments, you'll hear the toilet flush. Then you'll hear the sim washing their hands in the sink. Finally, you hear the shower. Then the sim comes out. Maybe the sink is above the toilet tank.
