We should actually use the proper term and call it the head. Exceptional woodwork everywhere with lots of storage and a ceramic washbasin, like in your...bathroom.
Hallberg Rassy also mentioned the possibility of a shower in their original marketing for this boat but even if there is a shower I think it’s really only an emergency one. There is a lot of wood which would get wet all the time and the showerbasin drains into the bilge. Not a good solution. It was ok at the time but it’s not up to the standards we have today on boats.
