6 Person Hot Tub Size: How Big Is it?

Knowing how big your hot tub is helps you make the right buying decisions and avoid problems that may come along the way. In this article, we’ll talk about how big a 6 person hot tub size is and whether it’s the right choice for you.

It’s not uncommon to hear stories of people buying a 6 ft hot tub online only to find they’re either too small for everybody or too big to fit in. Good to know you don’t have to go through the same experience. Here’s what you should know when buying a 6-person hot tub.

6 Person Hot Tub Dimensions: What’s Common?

Hot tubs usually come in 3 sizes: small, medium, and large. The average size of a hot tub that can accommodate 6 persons falls into the medium category which is 6 feet 6 inches to 7 feet 9 inches long and 6 feet 4inches to 7 feet 9 inches wide.

Hot tubs also come in different shapes. However, square hot tubs are the most popular ones as they are both space-saving and can accommodate more people compared to other shapes. For instance, a round hot tub of the same length (diameter) could accommodate 3 to 5 persons compared to 6 to 8 in a square hot tub.

The height for most hot tubs is 35 to 38 inches. It’s very important if you’re planning to install the hot tub indoors since standard door sizes in the US are around 32 to 36 inches. Otherwise, you can go for up to 38 inches or choose inflatable hot tubs instead.

Before buying a 6-person hot tub, make sure you have the following sorted out:


You need 80 to 90+ square feet of space for this size. There should be at least 1 foot of space on both ends to allow people to enter and exit comfortably. Above-ground and inflatable hot tubs take up a little more space than in-ground ones so keep that in mind.

The 6-person hot tubs are great for indoor and outdoor use as long as you have easy access to electrical outlets. If you want something you can easily move around, consider buying inflatable hot tubs.


Make sure your location is accessible. Check if your entrances and hallways have enough clearance for your hot tub to pass through without scratching or breaking anything.

Installation. Hot tubs need a flat, stable surface like concrete or lawn. Check with your local dealer if you want to install a hot tub on your deck. The base for your hot tub should withstand at least 125 lbs per square foot. 

Energy Consumption
