They do not have to. Of course, there may be some special considerations that will cause a deviation from this rule, but it is up to the designer and his rationale.

The decision and responsibility rests with the designer (contractor, when there is no project). Placing splash-proof fittings in kitchens and other rooms with water is in accordance with the art of construction (the expression "construction art", in addition to standards and regulations, also appears in the designer's declaration of installation compliance).
Without exaggeration.

This applies not only to sockets, also light switches have been placed in front of entrances and not in these rooms for years. Lighting should also be tight (in workplaces, because in the apartment everyone knows what they want).
This is a fantasy.

I once encountered a case of frequent RCD tripping caused by damp IP20 boxes in the kitchen under the ceiling.
A spartan installation cannot cause a policy change. A normally made can with normal connections is not allowed to cause similar symptoms even in clouds of steam.
But when someone tapes the twisted connections with a rotten tape ... we have effects as well.
