Kiwitub uses seawater as well as fresh water
This shot is at Murdering Beach, a small secluded bay north of Dunedin. Various friends were biking out or canoeing across and I’d gone ahead to set things up. A nice English tourist out for a walk by herself spied the tub: “What on Earth is this?” “It’s a truly portable hot tub.” “I’ve never seen anything like this!” “There’s never been anything like this!” “Can I get in?” “Sure.”
It’s a great way to meet people.
