What 6 seats costs to keep hot
At the class median of 309 gallons, holding 102 degrees F against a 50 degree average outdoor temperature with an average cover and $0.17/kWh power costs about $38 a month in heating energy. The class spans $30 for the smallest inflatable to $54 for the biggest hard-shell. A foam-filled cabinet narrows that gap in practice; thin inflatable walls widen it in winter. The running cost calculator takes your exact volume, climate, and rate.
Inflatable or hard-shell: two different 6 person footprints
The same "seats 6" label describes two different objects. The inflatable 6-seaters here are round, 68 to 107 inches in diameter, 24 to 31 inches tall, and hold 213 to 362 gallons. The hard-shell 6-seaters are mostly square or rectangular, 79 to 110 inches on the long side, 32 to 41.5 inches tall, and hold 240 to 520 gallons. If you are planning a pad or a doorway route, that difference decides the project.
The load when it is full
Water at 8.34 lb per gallon plus six adults at 185 lb plus the tub itself puts the filled weights in the table between 2,961 and 6,601 lb. At the top of that range you are parking the weight of two cars on one corner of the yard, so a ground-level slab beats a raised deck unless the deck was engineered for it. Check any model with the filled weight calculator.
6 person hot tub questions
How big is a 6 person hot tub?
It depends on the build. The inflatable 6-seaters in our database run 68 to 107 inches across and hold 213 to 362 gallons, while the hard-shell 6-seaters run 79 to 110 inches and hold 240 to 520 gallons.
How much electricity does a 6 person hot tub use?
Holding the class median of 309 gallons at 102 degrees F with a 50 degree average outdoor temperature and an average cover takes about 7.3 kWh a day of standby heating, roughly $38 a month at $0.17/kWh. The running cost calculator reruns it for your climate and rate.
What does a 6 person hot tub weigh when it is full?
Filled with water and six adults, the models here span 2,961 to 6,601 lb. Hard-shell models sit at the top of that range because the shell and cabinet alone can weigh several hundred pounds.
Does a tub sold as "4-6 person" belong in this class?
Yes. This page lists every model whose advertised seating range includes 6, so "4-6 person" and "5-7 person" tubs appear here alongside tubs rated for exactly 6. The rated seats column in the table shows each model's own advertised figure.
