Hands-free door locks for bathrooms?

Some quality replies and interesting discussion there folks, thank you! :pac: I reckon that 3-D printed yolk might do the job - it looks like it could be fixed to the kind of handles that are fitted to a wheelchair accessible bathroom, where it's pushed up to lock from the inside and pushed down to unlock and open. I could just go for those in all bathrooms.

Just to clear up some confusion - these are individual bathrooms, as opposed to having sets of toilet stalls & sets of shower stalls. There is no separate ladies or gents - each bathroom is self-contained with a toilet, wash-hand basin and shower (I did a fair bit of research as to which would be preferable, this or going for stalls and this was the more popular option by some margin - plus it's only a small campsite so this was actually the most efficient way of using the space). The taps for the sinks are the push-button kind which provide a stream of water for 20 seconds or so, meaning no need to touch them again to turn them off once you've finished washing your hands. There is only one door for each bathroom which opens to the outside*, so this has to be lockable by the user.

*The walkway immediately outside the bathrooms is screened so as to prevent any direct view into the bathrooms should anyone forget to lock the door!

PS I'm thinking of putting this up on every door ...

Cheers! I was a bit back & forth alright about what you're saying re occupancy duration in terms of someone using a shower preventing someone else using that bathroom's toilet. But there are eleven bathrooms in total, two with wheelchair accessibility, so I'm reasonably confident that nobody will be taken short for too long, at least in my first season or two. I'm only going to have seven glamping units and - given that there will probably be a need for greater physical distancing for some time to come - probably only a dozen spots for pitching your own tent instead of the 20 or so I had been planning on, so it definitely won't be overcrowded in the short/medium term. If customer numbers increase then I probably will look at the possibility of adding a couple of extra loos alright, but I've only one enclosed space left to put them in and I was toying with the idea of turning that into a drying room, i.e. a place where you can hang your biking/outdoor gear overnight and have it nice & dry for the next morning. That entire space is only about 8' x 4', so realistically it's either two extra loos or one extra loo and a very small drying room.

No can do, sadly. There were so many hoops to jump through in order to get planning permission through for the project in the first place (I'm in NI), and one of the arbitrary restrictions was that the only permanent structures permitted onsite were the facilities blocks, i.e. bathrooms, small campsite kitchen, reception. Having a games room or similar is the sort of thing that I could probably get through in the future subject to an additional application, but at the time I had to just make sure I got the go-ahead at all.

But I do have a fire circle to sit around, fruit trees where you can pick your own cherries etc in season and outdoor cooking stations and a stream to fish in. Other than that, how about a game of quoits or outdoor Connect 4?!! :pac::pac::pac:

I'd be bankrupted with replacing all the ping pong balls disappearing on a blowy day! :eek:
Joking aside, something like that might be an option when I've earned a bit of dough to pay for it, so thanks for the tip. Believe it or not, thanks to the planners I'm not allowed a children's playground with swings, seesaws etc so for the time being it'll have to be smaller games dotted around the place. That said, this is a bit of a micro campsite - there's only parking for about 26-27 cars and before the pandemic I was looking at setting the maximum occupancy for e.g. a bank holiday weekend at around 90, rather than accepting bookings to fill every single possible place, so it's never going to have all the facilities that bigger places do.
