What Size Hot Tub Do I Need?

When it comes to choosing a hot tub, size matters.

Get the Right Fit

Hot tub size is one of the main factors to consider when researching and choosing your spa. A hot tub is a long-term investment, so you’ll want to choose one that is best suited for you and your lifestyle. Whether installing a hot tub in your backyard, on your deck, or inside your home, you want to make sure it fits your space. Additionally, you want it to accommodate the right number of people, whether you’re looking for a small, couple’s hot tub, a medium family hot tub, or a large, party hot tub.

Hot Tub Size: What You Should Know

To determine what size hot tub you need, consider how many people you want to seat, why you’re using it, and what area you want to place it in. Maybe you’re looking for an intimate 2 person hot tub for quiet nights at home, or a fun, 6 person hot tub the whole family can enjoy. Keep in mind that the size of the hot tub can also affect cost – since there are usually more components to run and manage.

Let’s explore the options

Once you've made your decision as to where the hot tub will live, focus on the dimensions you have to work with and your installation options to maximize your environment. Snap a few photos and bring general measurements to your hot tub dealer, so they can show you which models are potential matches for your space.


There are three general hot tub sizes: small, medium, and large.

Small Hot Tubs

While hot tub seating can sometimes affect dimensions, did you know you can get more seating variety for just a few more inches of space? In fact, a common misconception about hot tub size is that you’re restricted to models with less seating options when space is limited. The good news is that a hot tub with more seating options often requires only a slightly larger footprint.


When thinking about hot tub seating and size, imagine who will be using your hot tub.

  • 2 to 3 seating options are ideal for couples, and best of all, alone time.
  • 4 to 5 seating options are the most popular, and usually accommodate small families or couples with guests.
  • 6+ seating options are perfect for large families are people who like to entertain.


Test out the different hot tub seating options in a dry and/or wet test to see which ones provide the most comfortable fit for you. Lounge seats and therapy seats are made for relaxation; loveseats are perfect for two. Cool-down seats sit higher above the water line and are great for children or taking a break from the warm water. And, more seats equal more massage combinations. Since they vary in size and depth considerably, make sure the seats are not too small or large. You can also ask your hot tub dealer to explain how different seats are designed and how they affect hot tub size.


Other important factors

In addition to choosing a hot tub that's ideal for you, you want to make sure you have ample space for it and make any necessary preparations before it's installed. Here are some items to discuss with your dealer:



You'll want to a solid, level surface before installing your hot tub. The ground or deck must be sturdy enough to support the weight of the filled spa and the people in it. A licensed contractor can help you select the appropriate foundation to fit within for your space.



When selecting the perfect spot for your hot tub, try to imagine when and how you'll be using the tub. Is there room to get in and out quickly and easily. What does the walking path around it look like? Also consider the privacy factor.
