Outdoor soaking tub with hot water: Hot tub designation?

[Diana Mulvihill]

Hi All, would love your thoughts ~

A set of 2 large clawfoot tubs as an alternative to traditional hot tub, with running hot + cold water spigot attached, hot springs style.

Pros could be: Clean water + tub for each guest; on a well, so no water waste concern; can make it design-y + cute; can be used winter (hot water) + summer (cool water); goes better with forest location of the home than a traditional hot tub might; will hold same number of guests as hot tub would (2 people in each tub).

In researching I have seen some people on Airbnb have these checked in amenities as 'hot tub', some 'private hot tub'. They have clear photos of what the tubs are, so there is no confusion, + according to reviews guests seem to love them as a hot tub experience. 

Any thoughts about listing as 'hot tub'? This designation seems to be the best fit, tho I would want to be sure it's allowed before I choose to go with this over traditional hot tub.

Thank you in advance to anyone who shares.
