Spa Capacity – How Big of a Hot Tub Do You Need?

hot tub how big

You’ve always wanted to have a hot tub in your backyard, and now you’re ready to take the leap and get one installed. How do you find the right model to meet your needs?

As you shop for a spa, you’ll need to consider several factors, including the power and configuration of the jets, the quality of the insulation, the upkeep required and whether you’d like any entertainment upgrades. But one of the most important decisions you’ll need to make involves the size and capacity of the tub.

For help figuring out how big of a hot tub you need, you can always turn to the professional team at Absolute Comfort Spa & Pool. The following guide explains what you need to know about spa capacity.

Spa Size Options

Generally speaking, manufacturers offer three sizes of hot tubs:

However, hot tubs in each size category come with a range of dimensions. The length, width and height can all vary – for example, one small spa may measure 6 feet long, 6 feet wide and 33 inches deep, while another model is 7 feet long, 5.5 feet wide and 30 inches deep.

A few inches might not seem like it would make a major difference, but that’s not the case. When comparing different models, think about both the number and the height of the people who will be using the hot tub to ensure a comfortable fit.

Spa Capacity Considerations

As you mull over your hot tub size options, you’ll also need to think carefully about where in your backyard to have your spa installed. To make a smart decision, consider the following:


The location you choose must be large enough to accommodate your spa and its foundation. The spot also needs to work for the cover lifter, which requires roughly 18 inches of clearance to operate.


If your backyard isn’t easily accessible, you’ll have to clear enough of a path to get your spa in place. This may mean removing a gate, perhaps, or you might need to cut back a few tree branches. Before scheduling delivery, make sure the path is free of obstacles.
