Volume of the tub = (4ft x 6ft x 2ft) = 48 cubic feet = 359.06 gallons (rounded),
whether or not there's anything in it.
A hot tub heat is transferred by convection. Most hot tubs use forced convection while the hot tub pump circulates the water.
Probably because the hot water pipes are right behind the front wall of the tub.
Answer A typical 6 person hot tub (empty) weighs about 650 lbs. add 300 gallons of water @ 9lbs. per gallon and you now have a total weight of approx. 3350 lbs. add in 4 adults with a average weight of 170 lbs. for a total of 4030 lbs. you must be able to support this amount of weight.
It depends on how big the pot and tub are, and the temperature difference between "hot" and "warm".
That depends on the volume/size of the tub in question. A "tub" could be a butter tub, a mash tub a bath-tub etc.
A US liquid gallon occupies 231 cubic inches. A cubic foot occupies 12" * 12" * 12" = 1728 cubic inches, so there are 1728/231 = 7.48 gallons in a cubic foot. The hot tub has a volume of 5 * 5 * 3 = 75 cubic feet. So it contains 75 * 7.48 = 561 gallons.
350 gallons
Depends how big your hot tub is. Mine is about 150 gallons or 1,200 pints.
The average-size hot tub holds approximately 475 gallons of water. The earliest known hot tubs were calderas. Hot stones were used to heat the water.
The number of gallons of water a Cal Spa hot tub can hold varies. Each hot tub in this brand is a different size and therefore can hold different amounts of water.
66 gallons
That could heavily depend on the total capacity of the tub, and on how full you fill it.

30.55 gallons (rounded) for every inch the water in the tub is deep.
There are so many different Jacuzzi-brand spas and tubs, no single answer is possible. A small spa (like an outdoor hot tub, but seating only 2 adults) will take about 200 gallons. A big one ranges from 320 gallons (4 adults) to as much as 450 gallons (6 -7 adults)! An indoor Jacuzzi bathroom tub is much smaller, with a 5-to-6-foot long tub running anywhere from 55 to 75 gallons. But this is such a common question that every spec sheet and every web site for any spa will have the gallons right up front. So looking here for "the" answer is only the first step in your research...
That depends on the dimensions of the tub, and also on whether or not anyone has put any water in it.
