Light connection wrong place guest WC

I wouldn't want to miss our ceiling light in the guest toilet (the mirror is still missing) here photographed from the floor upwards

That is of course cool and very individual. However, your description is also very elaborate, nowadays there are much simpler solutions. But as everyone else has already said, a light on the wall is also completely sufficient. In hotels, for example, ceiling lighting is rarely used anymore. It is always on the wall or attached to the furniture.

Mirror cabinet, something like that. Bathroom bright as day.

My phone display light on the toilet is enough for me ...

Unaware, one reads the thread here and gets a slight shock because it suddenly hits you that you actually have two light outlets in the guest WC (ceiling, wall). And you also wonder, what do you do now with both outlets in a small room?! how is your unused ceiling cable stored? Is it just hanging there, or cut back very short?

If necessary, there are such small white caps ( Das ist sicher nicht der Fachbegriff).

In case of emergency, there are these small white caps (That is surely not the technical term)

...but everyone knows them
