All I can offer you is that wife would kill for one but life got in the way even though we had a spot = raised deck near 220v 30a RV outside outlet and hose bib, plenty of drainage slope.
Designed a new house in-the-day and soon after move-in here comes the tub on rear deck & they also were "stars" in local ads trying to sell more tubs since they were well known.
Two years of bliss
Two years empty, a white elephant with wishes of it being stolen
Goodbye tub
No overt troubles on maintenance but one more thing to do for diminishing returns of pleasure.
These days one can set a timer for it to be HOT at the hour you plan to be IN it ... something they had not and one of the picky excuses to be rid of it when it just wasn't a match for their lifestyle.
Perhaps they are more of the hot tub/pool/lake/springs while on vacation sort?
Ten words or less ... a goal unattainable
