2 person hot tub sizes: the small hot tub class
A 2 person hot tub runs 67 to 81 inches across, stands 26 to 31 inches tall, and holds 160 to 177 gallons, small enough for the decks, patios, and balconies a full-size spa rules out.

What counts as a small hot tub
Of the 93 models in our database, 8 carry a manufacturer rating that covers 2 people: 1 hard-shell and 7 inflatables. Makers of small inflatables usually advertise a range rather than one number, so a tub sold as "2-3 person" or "2-4 person" is listed here and also on the 4 person page when its range reaches that far. If a tub is rated for exactly 2, it is only here.

What a small tub costs to keep hot
Less water means less standby heat loss. At a 102 degree set point, a 50 degree average outdoor temperature, an average cover, and power at $0.17/kWh, holding 160 to 177 gallons at temperature runs about $25 to $26 a month in heating energy. That is the floor for a covered, well-kept tub; jets, wind, and lid-off soaks add to it. Put your own climate and power price into the running cost calculator.
Will your deck take it?
Even the lightest 2 person tub in this group lands near 1,779 lb once it is full of water and people, and the heaviest reaches 1,936 lb. Spread over a small footprint that is a real structural load, so check the filled weight calculator against your deck's rating before committing to a spot.

Is a 2 person hot tub the same as a small hot tub?
Mostly, yes. Retailers use "small hot tub" for anything rated around 2 to 3 seats. This page lists every model whose manufacturer rating covers 2 people, including tubs sold as "2-3 person" or "2-4 person", since those are pitched at the same buyer.
