The lavatory thing is easy to workaround, at least. One entrance, and as many sinks as you have toilets. You can have a large bathroom, rooms with a bathroom attached, etc. As long as there's one way out and the sinks are there.

Much more annoying are the suits (and now, gas masks). If you are not careful with settings they will drop them elsewhere, or will enter the perfectly breathable base with suits still on.
