How to Measure Your Outdoor Space

First, we recommend measuring the square footage of your outdoor space to give you a good idea of which hot tub size to choose. To calculate the square footage of your patio, deck, or yard, measure both the length and the width. One easy way to do this is by walking the distance and measuring one stride as 3 ft. After recording the length and width, multiply the two measurements to find the square footage of your total outdoor space. Knowing your space’s square footage will help you understand how much room you have for a hot tub, based on how much of your total space you’re okay with it taking up.

Tip!

Hot tubs need an additional 12" to 15" of space around all sides to allow you to get in and out of the tub with ease, as well as perform any necessary maintenance, so make sure to factor that extra clearance into your measurements. For example, a hot tub that is 5'4" wide would actually need a space that measures 7'4" wide.

How to Choose the Right Hot Tub Sizes

、

Once you’ve identified how much total room there is for a hot tub in your space, think about how big you want the hot tub to be and how many people will use it at the same time. Consider how many people are in your household, as well as the approximate number of guests you’ll want to use it with. This will help you decide which of the many hot tub sizes will be a good fit and how many seats you'll need.

Small

If you have limited space, a small hot tub is a great option for you. The dimensions for small hot tub sizes range from 5'4" to 7" long, 5'4" to 6'8" wide, and 33" to 38½" tall. This size provides enough seats for two or three people and fits well in compact outdoor spaces, such as small patios or decks.

Medium

The most popular size, medium hot tub sizes often measure between 6'6" to 7'9" long, 6'4" to 7'9" wide, and 33" to 38½" tall. They comfortably sit four to five people. This size is roomy enough to allow you to relax with family and friends without the hot tub dominating your outdoor space. Medium hot tubs are well-suited for backyards or medium-sized decks.

Large

Large hot tub sizes typically measure 7' to 9' long, 7' to 9'2" wide, and 33' to 38½" tall. This hot tub size sits six to seven people comfortably and is perfect for larger outdoor spaces. Large hot tubs are ideal for spending quality time with friends and family or stretching out with just a few people.

Extra-Large

If you have a large household or love to entertain, an extra-large hot tub is spacious enough to fit everyone. Extra-large hot tub sizes can measure up to 11" long and 11" wide. This size is best for expansive outdoor spaces and requires plenty of room for installation.

Additional Considerations

When choosing the best hot tub sizes, there are a few additional factors to keep in mind.

Placement

Hot tubs need a strong, flat surface with close access to water and electrical supply. As noted above, we recommend leaving a few feet on each side of the hot tub to make maintenance easier. This provides enough room to drain the hot tub and offers plenty of space to make maintenance repairs.

Consider creating a clear pathway to and from the hot tub. A direct path can help you avoid slippery surfaces, improving your hot tub safety. This idea is also great if you plan on using your hot tub in a cold climate, since having a direct path makes it quicker, easier, and less chilly to walk from the door to the hot tub.

Weight

Hot tubs are heavy and require a sturdy foundation. An empty hot tub can range from 500 to 1000 lbs. while a hot tub filled with water can weigh as much as 5500 lbs. A small hot tub filled with water usually weighs 3000 lbs. A medium-sized hot tub can weigh 4500 lbs and a large hot tub is often 5500 lbs. When choosing a hot tub, it's important to ensure that your deck, patio, or yard placement has enough structural support to hold the weight of the hot tub and the people in it.

Delivery

To ensure a smooth delivery and installation, map out the route the hot tub will take on its way to its destination. Measure any entryways or gates that the hot tub could pass through to make sure it will fit.
