On the other side of the bookshelves, there is a square glass room that lights up with the rest of the room. This bathroom can be accessed by pulling open one of the glass panels. As soon as you step inside, the glass becomes opaque. The bathtub rests near one side of the ralls, and the upper edge is lined with blue, neon lights. Next to it, further back, is a floating island with two sink bowls on top.
There are indentations for specific toiletries, and those slots light up whenever an item is placed inside of them, so it is easy to track what Jay actually has.
Similar to the bathtub, the toilet is solid black, but with a blue neon glow under the hood, and it is close to the shower, which is simply a smaller glass casing with a bench indentation and a waterfall style faucet.
