Round Hot Tub or Square Hot Tub – Which Hot Tub is Better?

Round Hot Tub or Square Hot Tub – Which Hot Tub is Better?

Today, we’ll go over all the basics to help you decide if a round hot tub or a square hot tub is best for you and your backyard. We’ll cover everything from design, backyard fit, and functionality.

There are so many options you never thought you’d ever really think about when you started your hot tub shopping journey. The shape of your hot tub is definitely something you want to make the right choice about. So, round hot tub vs. square hot tub – which hot tub is better?

Fitting A Round Vs. A Square Hot Tub In Your Backyard

You can see in the diagram above an overhead view of each hot tub option in an illustrated backyard. This gives you a good idea spatially of how each will fit in a backyard setting. Generally, a square hot tub is going to fit more efficiently in a backyard as you can tuck it into a corner or have it flush up against your house or deck. A round hot tub can still fit into a corner or up against your house, however, there will be excess space in the corner or around the sides of the hot tub. Aesthetically, square hot tubs are usually the choice for this reason. If you’re sinking your hot tub into a deck, although a challenge for your contractor, the “extra space” isn’t a concern. So, it comes down to what you want your hot tub to look like in your backyard or how you’re planning to install it!

Seating Arrangement of Square Vs. Round Hot Tub

This is probably the most important part you want to consider when deciding between a round hot tub or square hot tub. You can see in the diagram above how 4 adults will fit in each type of hot tub. Although these two hot tubs are similar in gallonage, the seating arrangement in the round hot tub is a much tighter fit. This is simply because a square hot tub allows for adults to sit in the corners of the hot tub giving everyone more leg room. So, when it comes to seating comfort, the square hot tub wins every time.


Aesthetics of A Round Vs. Square Hot Tub

The last thought you want to consider when choosing between a round or a square hot tub is just personal preference. What do you like the best aesthetically? Do you prefer the look of a round or square hot tub? This is something you have to decide on your own. Also, weigh the other factors in to understand ultimately what your choice is. The photo above can give you a better idea of what a round hot tub looks like in a backyard vs. a round hot tub. However, we have an even better tool for you to help you decide below.
