(EDITED) In the processing of designing and planning a major reno. The only bathroom (until we can build another one in the basement in a few years) is very small, no storage (for a dozen towels, TP, toiletries, etc)

We are thinking about the European style of having the sink outside of the bathroom. Just in the hallway alcove outside of the bathroom) I cannot find any good photos of it in use in homes for reference.
Any thoughts on making it work ? Or if it would be too weird.

The main issue is that we need storage for the bathroom. The current layout does not allow for much storage. (pictures added in comments below)
