The attic kitchen and boatroom assembly is complete.
The bathroom is right to left; Shower, cabinet with sink, toilet with bidet shower (bum gun) and the water boiler. The conversation with engineer, Jorge, was that we could not reestablish an actual bidet.
The heater could have either been placed in the kitchen or in the bathroom. Seing the installment I am quite happy with the solution.

In the kichet (or 'kichenette') the two stove cook top from Ikea is working fine. The cook top size is adding more working area table space.
Regarding color composition - I think that has turned out quite well. Kudos Jorge!
Super happy with the outcome.
