My guess would be that bathrooms can get steamy whereas a laundry room isn't.

And there are typically wet naked people wandering around a bathroom that might accidentally touch something electrical, whereas you'd normally be dressed and dry in a laundry room.

That would be uncomfortable.

^^^ but yet provide much needed relief for the stress of the 911 operators.

I would have still preferred the option to build a 5x6’ utility closet around the box “inside the bathroom” rather than end up with a 5x7’ bathroom inside the utility room.
