There's a porthole in the front of the sub, where the toilet is.

Funny enough, I've also seen "it doesn't even have a toilet" repeated around HN in the last couple days.

IIRC an earlier design or planned design used cameras only.

Edit: Wow, they were actually sued by a whistleblower over the pressure rating for the window on an earlier design! https://newrepublic.com/post/173802/missing-titanic-sub-face...

Yeah, I think I made a mistake when researching if it had a window. It clearly had one when the reporter went down last year.
