When you’re weighing up which hot tubs are right for you, one of the most critical elements is the size and dimensions of the hot tub. Get this bit right, and it’ll make a massive difference to your ownership experience and enjoyment of your hot tub.
Hot tubs come in a wide range of sizes that are suitable for a variety of backyards and spaces.
Before you go shopping for your hot tub, spend a few minutes reading this post. While all the fun things such as LED lighting, jets, and other extras are important, the hot tub size should be at the top of your list of priorities.
Which are the 3 Main Hot Tub Sizes?
Generally, hot tub dimensions can be categorised into three groups: small, medium, and large.
The average size of a hot tub is between 7’ square and 8’ square. However, you’ll also find hot tubs that are much larger than this, for example, 9’ square and even larger.
Small Hot Tubs
Small hot tubs will fit two to three people comfortably. This is a perfect size if space is limited. You and your partner will be able to enjoy a relaxing spa together.
Small tubs easily fit into a backyard and don’t cost as much as a larger hot tub. If it’s only ever going to be you and your partner in the hot tub, this is the best choice.
Medium Hot Tubs
Medium hot tubs will comfortably fit four and six people. They tend to be the most popular size because they allow for more flexibility. Small families or couples who want to invite visitors for a dip would find this size the best fit. It’s also a good size if you want extra personal space for relaxing.
Large Hot Tubs
Large hot tubs are suitable for seven people or more. It’s ideal for larger groups of people or families. One of the most significant benefits of a large hot tub is that you’ve got so much more space for relaxing.
It would also be a good purchase if you happen to be tall and would appreciate a little more legroom.

What is the Standard Hot Tub Size?
Ask any hot top retailer, and they’ll probably agree that the most popular and common hot tub dimensions are those considered to be medium spas. However, we should point out that there’s no such thing as standard hot tub sizes or one-size-fits-all.
The hot tub dimensions we’ve already mentioned are also only meant as a guideline. A medium hot tub, for example, might be designed to fit 4-6 people, but it really depends on their shape, size, and how much personal space they prefer.
As well as typical hot tub dimensions, various other factors also have a bearing on whether a hot tub is right for you. For example, the seating configuration, the water’s depth, the breadth and width of the hot tub vary immensely between models.
This might make it all sound very confusing, but on the plus side, it means you’ll have no problem finding a hot tub that matches your preferences.
On the negative side, it does make it a little more challenging when it comes to comparing and narrowing down your options.

How Big of a Hot Tub Should I Get?
There are a number of things to take into consideration when you’re picking the size of your hot tub.
How Many People Are Going to Use the Hot Tub?
How many people are going to use the tub matters. In the smaller units, there will only be a few seats. Yes, people can float around in a hot tub, but being able to sit will make for a more enjoyable hot tub experience.
Where Will You Locate Your Hot Tub?
Make sure you choose a location that is big enough to fit your hot tub, including the foundation. If you’re not sure about the best location, your local dealer should be able to offer some advice.
Maintenance Access and Foundations
A general rule of thumb is to allow for 30cm of clearance on three of the sides. For the access door, you need to allow slightly more clearance, around 40cm should be enough.
Accessibility
There also needs to be enough access for everyone to get in and out of the hot tub comfortably.
For a two person hot tub this isn’t much of an issue. However, for larger tubs, if there’s only one way to get in and out people will have to shuffle themselves around each other. This won’t make for a very relaxing experience.
Cover Lifter
If you’re using a cover lifter, you need to allow additional height on one side of the tub. This factor is especially important if you plan to build a housing for your hot tub.
Delivery
Finally, before you place your order, make sure you measure up for the delivery process. Consider walking the same path the delivery team will have to use when they deliver your hot tub to your garden. Make sure there is plenty of room, paying particular attention to low-hanging branches and other obstacles, and don’t forget tight corners.
