A census of Lighthaven's public bathrooms
There are 13 public bathrooms on Lighthaven campus. 5 have showers, 3 have bidets, and only 9 of them are pictured on the map.

Let’s start with the bathrooms in Darwin, where I’m staying. There are none. I think some of the rooms have en-suite bathrooms, but mine is not one of them.
The closest bathrooms are in Cantor, both inside Inkhaven’s winner’s lounge. You’re only allowed into the winner’s lounge after having posted. Conveniently these have 2 of the 5 showers. Don’t tell Ben Pace that I regularly sneak in here before posting for my morning shower.
The dial on the faucet is reversed, first hot water, then cold. I assumed I’d have to take a cold shower the first time I showered here.
This bathroom has a very spacious floor plan.
What is that little gray square in the corner?
Toilet paper holders are surprisingly rare throughout Lighthaven, but at least there’s always a large stack of toilet paper rolls nearby. Very efficient I suppose.

Other than the lack of toilet paper holder, Cantor’s other bathroom is by far one of the least remarkable.

One morning, looking for a shower that was not in the winner’s lounge, I came across this monstrosity attached to the gym in Eigenspace.
This would be one of the nicest showers if it had better water pressure.
Eigenspace’s ground floor has my favorite sink for shaving: the sink and mirror are particularly tall.
It also gave me a new entry for my collection of bathroom gender signs.

This teeny tiny sink in Eigenspace’s upstairs bathroom is cute. It’s clever that it attaches to the toilet tank to avoid needing a separate water line.

Upstairs, Aumann hides the only shower/bidet bathroom. It’s a bit too far and on too direct a path through the kitchen for me to want to use it in the morning.

Aumann’s two main downstairs bathrooms are probably the most frequently used. I enjoy their nice hardwood aesthetic.
“Click!”
Surprisingly rather than the door with the sink, it’s mostly the latch’s contact with the cabinet makes this sound.

The second bathroom has got your back even if you forget to lock the door.

Based on Cowboy Bebop’s name and premise and bathroom alone this is exactly what I imagined:
It makes for a nice view while you sit down for a longer squat on the pot.
I won’t give any hints for finding this bathroom because it is one of my favorites.
That rounds up Aumann’s bathrooms.
Bayes has the last shower, conveniently tucked away in the comfiest room: Bayes Attic.
I think the shower is rarely used, there were some insects in the drain when I tried taking a shower here.

Bayes also has two bathrooms hidden behind this sometimes locked door on the ground floor.
I wonder what all this shelving is for.
I had no difficulty finding the sink in this one.
The final bidet is in Bayes’ basement. It automatically dispenses blue cleaning liquid too.

This completes our census of Lighthaven’s public bathrooms. Let know if I missed one! Due to my completionist tendencies, I likely won’t pass up even a private/en-suite bathroom.
