Have you ever wondered about the amount of water a hot tub holds? Many people consider hot tubs to be luxurious investments that provide a relaxing experience, but it can be intimidating to figure out how much water is actually in one. Understanding how much water a hot tub holds is important for maintenance, as well as calculating how much energy and chlorine are required to keep the water clean. In this article, we’ll cover how many gallons of water are in a hot tub and how to estimate the size of the hot tub.

The Average Size of a Hot Tub

Typically, when individuals buy a hot tub, they want to know how many people it can comfortably hold. The average size of a hot tub is between 200 and 880 gallons, depending on the type of hot tub and its size. The range of sizes means larger hot tubs that can hold more people usually hold more water. Generally speaking, smaller units typically hold fewer than 400 gallons and are designed for smaller areas.

Size Categories

The types of hot tubs can be broken down into three different categories: small, medium, and large.

Small Hot Tub

Small hot tubs are usually designed for two to three people and tend to be used in smaller areas. Examples of small hot tubs include corner hot tubs and intimate two-person hot tubs. They typically hold between 80 and 400 gallons, with some holding as little as 80 gallons.

Medium Hot Tub

Medium hot tubs are typically used by three to five people and hold between 300 and 800 gallons. Some of the popular spa designs are swim spas and medium-sized round spas, but large octagon hot tubs also fall into this category.

Large Hot Tub

Large hot tubs hold between 800 and 880 gallons of water and are designed for five people or more. While some of the larger round hot tubs that hold six people are designed for more expansive areas, there are also large spas designed for more intimate spaces.

Estimating Hot Tub Water Capacity

If you’re not sure of the exact water capacity of your hot tub, don’t worry. You can estimate the size of your hot tub and determine how many gallons of water it holds by looking at the dimensions of the unit.

The average hot tub holds between 80 and 880 gallons. In order to figure out how much water your hot tub holds, take the volume of the tub and multiply it by the depth of the water. Do this by measuring the length, width, and depth of the tub in feet; then, multiply the three measurements together. This will give you the volume, which you can then multiply by the depth of the water.

How to Calculate Hot Tub Volume

One way to calculate the volume of a hot tub is by using the average measurements for hot tubs. Industry standard sizes for hot tubs range from 4-6 feet in width and 4-8 feet in length, although many models are smaller or larger. The average depth of a spa is around 28-38 inches, and this will help you determine the water capacity of the hot tub.
