I want to give them the benefit of the doubt and say perhaps it’s a deep freezer that is only opened occasionally, and I guess is pretty well sealed as long as it’s closed.
The kitchen appears to have one of those built-in fridges that matches the cabinets:
If there is not enough space in the rest of the house and this is the only place where it fits, well, that’s it then.
I would do about everything to avoid that, primarily because of the hygienic aspects but also because of the above average air humidity in a bathroom.
