Hot Tub Gallon Calculator
This calculator helps you estimate the number of gallons of water your hot tub will hold based on its dimensions and shape. Simply enter the length, width, and average depth of the hot tub in feet, select its shape, and click “Calculate”. The calculator will provide an estimate of the total gallons of water.
How it Works
The calculator uses the following formulas based on the shape of the hot tub to estimate its volume in gallons:
- Rectangle: Length x Width x Average Depth x 7.5
- Oval: Length x Width x Average Depth x 6.7
- Freeform: Length x Width x Average Depth x 5.9
These formulas take into account typical space inefficiencies and rounding within the shape categories.
