Okay, while I realize that this isn't "The Sims", and that a bathroom isn't vital, I'm nonetheless surprised The Sink doesn't have one. In fact, I'd say the devs missed an opportunity here. Imagine a talking bathroom mirror that does your haircuts for you (yes, I'm aware the Auto-Doc does this, but a bathroom mirror handling that job makes more sense than an Auto-Doc that duals as a hairdresser) and the comedic possibilities in a talking toilet (that also requests and recycles plungers) are limitless.

Ah, well.

In the Sink's defense....

You always have the cleanliness-obsessed sink and a load of soil. That pretty much counts as a bathroom.

Fertilizer. :spotted owl:

Well, you have to take in consideration that they are Robot Brains in Jars. Even your Brain states you can get a lot more done without looking for a place to urinate every now and then.
