When are we going to decide on a good word for "bathroom"?

Bathroom - nope, doesn't always have a bath in it

Toilet - saying "toilet" feels like biting into a lemon

Loo - is baby talk

Mens' room / ladies' room - get your binary ass out of here

Restroom - honestly, this chair is not comfortable

Water closet - this is probably the most accurate but how do I say it without adopting an accent?
