If you are looking for a hot tub to fit your space, the great news is that hot tubs are available in three different categories, each with standard sizes. So, whether you have a small space or a large space for a hot tub, you should be able to find one to fit.

These are the standard hot tub sizes:

How Big is a 2-Person Hot Tub

Hot tubs that fit 2-3 people can comfortably fit 2 people sitting side-by-side and face to face, while some models include a space for a single person to stretch out on one side of the tub, with space on the other side of the tub is for 2 people to sit facing each other.

A small hot tub is ideal for small spaces and considerably cheaper than a larger one. The smallest model available on the market is 5’4″ L x 5’4″ W (1.6m x 1.6m) x 29″ – 35″ H (73.6 – 88.9cm), so you do have the choice of purchasing a tub that only has 2 seats with a bit more leg room or a tub that is designed for 3 people.

How Big is a 4-Person Hot Tub

A 4-person hot tub is technically a small hot tub. It has seating areas for 4-people sitting side-by-side and facing each other, but due to the tub size, this arrangement can be a bit cramped. If you are going to have 4 people sitting in this tub together, make sure you are on friendly terms!

The dimensions of a square 4-seater hot tub is generally 6’2″ L x 6’2″ W x 2’10” L. (1.8m x 1.8m x .64m)

How Big is a 5-Person Hot Tub

A 5-person hot tub falls under the medium-sized hot tub category. A 5-person hot tub is 7’1″ H x 7’1″ W (2.1 x 2.1m) with a depth of 3′ (.91m) and weighs around 295lbs (133kg) when the tub is empty. A 5-person hot tub filled with water can weigh 2086 lb (950kg) when filled up to 6 inches below the rim.

The seating arrangements vary from tub to tub because of the shape. The general seating setup is 3 seats on one side of the tub with 2 on the other side of the tub. An octagonal-shaped hot tub has seats arranged around the tub at every corner, allowing for more leg room in the center.

How Big is a 6-Person Hot Tub?

A 6-person hot tub is generally a rectangular design to accommodate all the seats comfortably. Technically a medium-sized hot tub, the dimension of this tub is 7’8″ L x 8’4″ W x 2’10” H. (2.3 x 2.5 x 0.64m)

The seats are spread out around the tub, allowing the user to sit with his back against the side and legs in the middle.

A tub of this size can weigh up to 6000 lbs (2700kg) when full, so make sure that the location where you will install the tub can handle the weight. Factor in the weight of the 6 people in the tub while it is full.

How Big is a 7-Person Hot Tub

Large hot tubs range from 7’9″ L x 7’9″ W x 38″ H (2.4 x 2.4m x 96.5cm) and can accommodate 7-people or more.

A 7-person hot tub is a pure luxury! The tub’s shape determines the seating arrangements, but seats are generally placed around the tub, side-by-side, with the user sitting with his back to the wall and legs in the middle.

Some models are equipped with one or even two lounger-style seats allowing extra room to relax when only a few people use the tub at a time.

How Big is an 8-Person Hot Tub

An 8-person hot tub is classified as an extra-large tub. With dimensions of 11’L x 8’W x 3’H (3.3 x 2.4 x .91m), if you have the available space and the budget, a tub of this size is designed for comfort and space.

These tubs are large enough to comfortably seat 8 people around the tub with their backs to the side of the tub and legs in the middle. Some tubs accommodate 9 people, while others have 7 seats and a lounger!

How Big is a 10-Person Hot Tub

A giant 10-person hot tub can comfortably accommodate 9 – 10 people. The seating configurations depends on the tub’s style, with seats and loungers available in the tub.

This a large tub, generally about 100″ L x 100″ W (2.5m x 2.5m) and weighing close to 8000lbs (3628kgs) when filled with people and water.

Another option for a hot tub of this size or larger is a swim spa. A swim spa offers the same benefits as a spa or hot tub. The water is heated, and it does sport hydromassage jets, perfect for that relaxing soaking experience at the end of the day. 

An inclusive seating area is provided inside each swimming spa, but the tub is bigger and holds more water – a plus for larger families who like to spend time quality time together or for socializing with a group of friends.

While a hot tub is generally designed for a few people at a time, a swimming spa has a bigger capacity as it is geared towards a bigger group of people or is used for individual workouts.
