Generally “the zones”  stop at fixed partitions, walls and so on that do not move, and at the entrance door to the bathroom - as the assumption is presumably that it would be immodest to shower with the door open, and all these objects will intercept water splashes .

Now as an aside   I'm not sure that the writers of the regs are particularly worldly wise or well traveled sometimes in the assumptions made about behaviour like that, but there we are.

Now you do not say where this cupboard door is, in relation to the bath or shower head etc, but you could ask ‘if it was left open, would anything electrical get wet ?’

As it happens it sounds like nothing inside matters if it gets wet with some odd drops anyway, so even if the door was taken off the cupboard completely you would be OK.

However, for future notes or for other readers, if there was an accessible 13A socket in the cupboard, then you may need to consider it a regs non-compliance. How seriously to take that non-compliance  would depend on the likelihood of getting it wet, or of a wet handed user fresh out of the tub reaching in to do something with it… the bogey case everyone raises is the use of a hair dryer that then gets dropped in the bath while plugged in and someone is in the bath

 Unless it is a big bathroom and a 3m offset can be maintained. Not sure there are many hair dryer leads that long, or indeed that anyone in their right mind does that, but again, it is a (safe?) assumption.

The other consideration is condensation, and that all depends on temperatures of outside walls being colder  etc and how good the ventilation is, and what to do is not really well defined in the regs but still needs thinking about properly.
