MaxSez: Been there, Done That! What Trash Hauler has this factory installed “Type/Design” Lav in all models
Oh Max. Straight from the wiki page of Aircraft Lavatory.
B77L - Air Canada :PPP
Hmm, this is kinda a crappy question. Yay, puns!
In all seriousness, I have no idea.
Looks Like a Boeing to me. More squareish windows.
Looking at the amenities I would say a long haul Boeing plane, most likely a 777.
Looking at the wall, something is written in French.
It’s most likely an Air France OR Air Canada 777.
I’ve never seen a lavatory which has a window next to it on a aircraft before.

Going off of what @dush19 said…
MaxSez: @dush19 Wins with 1st correct response Everybody else Thanks and it was a “Crappy” question, LOL
Not sure I see the purpose of this, the quality of airplane toilets perhaps? 🤔
What if someone is outside the window and looks in? o.O
Probably no one looking in at 35,000ft :)
Seriously though there are also loos on the 747 with a window and usually they go opaque on the ground.
I told you! LOL, that’s great lol
the subject line made me lawl
