Been on my list for a while - a quiet replacement for the noisy bathroom pull
cord switch. If it came to it I could look into the kinetic/wireless type
switches, although that'd be quite expensive and relatively involved. Or a
PIR. But really a quiet pull cord would do. Any suggestions?

We have those same (h/d - noisy) pull switches in a few places and I
have 'replaced' them with smart switches / PIR sensors via a d-i-y
Home Automation solution.

For the kitchen, hall and landing they are all on PIR's and so very
handy when carrying stuff up / down the stairs (laundry etc) or
entering / leaving the kitchen whilst carrying plates etc.

With the kitchen PIR I have it set up as 'occupancy' and as yet, it's
not gone off whilst anyone has been out there but they go off after 5
mins of no movement.

If you want to retain the existing bathroom lighting (it won't take
'smart' lamps etc) you can do so with a suitable (~£10) switch (that
can be overridden with the existing switch).

Mines currently running on a Raspberry Pi with a £5 (ZigBee) dongle
and the basics were very easy to set up.

My BIL had an occupancy sensor in the wet room they built when the MIL
became less mobile and lived with them and I was always envious /
fascinated with how 'efficient it was.However, I think if you sat on
the loo it would switch off so I'm going to try putting a PIR in ours
to see how 'good' it could be (see if it maintains the 'occupied'
status when I'm in there reading). ;-)
