Yeah – we’ve had "f*ck you" neighbours too.
Ten minutes is the recommended maximum time to spend in a hot tub (at 37deg to 40deg C) less if you are pregnant.

My friend has one that he likes to entice ladies back to. We call it the gene pool

The cheap spas ARE noisy, and chavs usually don’t spend a lot on their jollies. That’s your first clue.
Yeah, our ex NDNs loved a hot tug too, but not the sort mentioned in page 3 above…
Current NDNs - luckily no tubs yet. Previous place - bloody awful. Adult sex parties with no care for the very close neighbours/kids. Unsupervised teen kids using it (and each other - gross) at least the boys got out to piss against our fence. Yes, OUR fence. Many happy years there - the last few were hell on Earth because of this.
I am however, quite prepared to accept that the polite and hygienic use that others have described here exists – we’ve just never experienced it personally. So, are we judgey/hysterical? Well, if you love the smell of rancid piss and chloramines on a lovely fresh Monday morning, yay, suggest the NDNs get one immediately!

Eeeeew. You do realise that chlorine is odourless.
The 'chlorine' smell is created by chloramines, which only build up when the pool water is improperly treated. Chloramines result from the combination of two ingredients: (a) chlorine disinfectants and (b) perspiration, oils and urine. Your neighbours are likely pissing in their hot tub!!! Gross.
Not 100% true – using dichloro granules at the correct strength will give a faint bleachy smell. The requirements for a spa tub though, are significantly higher than a swimming pool because of the warm water. and the behaviour If it doesn’t smell a bit like a naice floor cleaning liquid when you get in, don’t linger. I’d never use one unless there’s a cool, properly maintained swimming pool adjacent.

…It's been a lovely to cool off in the evenings during the heatwave.
You’re not running a hot tub correctly if you can ‘cool off’ in it.
As for people who claim ‘they’ don’t urinate in it - dream on, you have no idea about the person next to you…
