How to Choose the Right Hot Tub Size for Your Home

Buying a hot tub is an exciting investment. Choosing the right size for your home can be tough though. From backyard space to family size and entertainment plans, several factors influence what size hot tub you should buy.

Here are some helpful tips to consider before you start shopping to help how to choose the right size hot tub for your home:

Tip 1. Consider How Many People Will Use It
Think about how many people will regularly use the hot tub. A small 2–3 person spa is ideal for couples or solo soaking, while a 5–6 person model works better for families. For entertaining guests, consider a 6–8 person hot tub.

Tip 2. Measure Your Available Space
Before falling in love with a model, measure your backyard or deck. Leave at least 18 inches around the spa for maintenance access. Consider where the steps, cover lifter, and electrical hookup will go.

Tip 3. Think About Comfort and Jet Layout
Larger hot tubs usually offer a better range of seating options (e.g., loungers, captain’s chairs) and more targeted jet placements. A great way to get a sense of comfort is to dive on in.  This may sound odd, but sit in a dry tub at the showroom to test the layout.  Its like trying it on before you buy.  Get a feel if it’s a fit for you and the level of comfort you want for soaking after a hard day.

Tip 4. Factor in Energy Efficiency
Running a hot tub comes at a cost, so the more you can do to reduce operational costs, the better.  Smaller tubs typically heat faster and cost less to operate, so if a 2-3 person tub is a right fit for you, you should be able to keep operational costs down for your new hot tub.  For larger hot tubs, consider purchasing high-quality insulation and covers to increase energy efficiency.

Tip 5. Future-Proof Your Decision
It’s easy to underestimate how often friends or extended family might want to use your spa. If in doubt, go slightly bigger to avoid buyer’s remorse.  Here’s a general outline on hot tub sizes:

Common Hot Tub Sizes:
2–3 person: 5’4” to 7’ x 29”–35” high
4–5 person: 6’4” to 7’ x 33”–38” high
6+ person: 7’ to 8’+ x 36”–40”+ high

Final Tip. Match Your Hot Tub Size With Your Lifestyle

Deciding on a hot tub size really comes down to accommodating your main reason for buying.  If you value personal relaxation, fast heat-up times and are unlikely to be hosting a lot of people, a smaller tub may be perfect. But if it’s about family time or socializing, and you have the space to play with, go with a bigger hot tub.
