What is the Difference Between a Jacuzzi & Hot Tub?

When people talk about a jacuzzi, they’re probably referring to the type of hot tubs installed in hotels, spas, or resort rooms. A circulating water pump frequently feeds jacuzzis. On the other hand, hot tubs are typically provided with evaporated water from a swimming pool and can have a circulating pump. The differences between a jacuzzi and a hot tub are easy to guess, but what’s more important is understanding when it’s best to use each one.

There are four quick and easy ways to tell the difference.

The water in hot tubs is usually heated to the desired temperature before the main motor kicks on. You can tell by the position of the jets. The jacuzzi situation is a bit more complicated, especially for those who want their spa to be set up in their own house.

Here’s how it goes:

Hot Tub Mixes At Different Speeds

In a hot tub, the water flows out of each jet at different speeds, which causes a rippling effect that creates beautiful horizontal lines on each side. That is why people like to relax on a hot tub’s water jets and stare at the sky. All those beautiful colours are reflected in the water cascading down each jet. In a jacuzzi, the flow of water rotates in one direction as it pours out of each jet. That gives you a large patch of bubbles on each side of your body that doesn’t look great.


Hot Tub Feels Great With Your Feet Down

When you’re on the water jet of a hot tub, your feet are sticking up from the water. On the other hand, when you’re chilling on a jacuzzi’s jets, your feet feel great when placed back down. That is because of the bubbles created by a jacuzzi’s motor, giving you that soft massage feeling. If you want to enjoy a spa session with someone else but don’t want to touch them, it’s better to use a hot tub because it allows enough space between two people without their legs touching each other. That is why public spas prefer hot tubs like those in malls.


In the jacuzzi, your feet can feel good even if they’re free to float around the water’s surface, but it isn’t as comfortable as in a hot tub. If you have sensitive legs and feet, a jacuzzi will easily reduce their sensitivity. On the other hand, if your legs have been battered by years of playing tennis or you have poor circulation, then a hot spa is much better because it has more water jets that will provide more circulation and stimulate blood flow to your legs to get rid of soreness.


Hot Tub Mixes Naturally

It’s important to know whether the hot tub circulates its water or if it uses the water once produced by a swimming pool. Hot tubs tend to be made in a way that they expose more water jets, thus allowing you to soak deeper. The newly introduced rotating jets are nice, too, no matter what brand you use, but it’s best to stick with the traditional ones.


The circulating hot tubs, though expensive, guarantee that the water in them is clean. You can see for yourself if this is true by looking at how the bubbles are formed and how nicely they reflect on the surface of each jet.


The spa jets can last for years if you regularly clean them and follow the owner’s manual for some maintenance. Make sure to look at the water level in the tub once in a while. You need to check if evaporation is taking its toll on the water.


Hot tubs typically use chlorinated pool water, but you can also use boiling water if you have it. If you plan on using garden hose water or river water, ensure that these are filtered first with a pool filter before using them in your hot tub, as this keeps unwanted elements out of it.


Hot Tub Temperature Is Higher

The average temperature range of a hot tub is 86° to 104° F, which is just right for people who want to relax. The heat in these spas gets pretty intense once you adjust its thermostat, especially if you’re using a motor that simultaneously pumps hot and cold water into the same tub. You can customize the temperature depending on what you prefer.


For example, if you plan on using your spa during winter time and want to enjoy its bubbles instead of soaking in them, then temperatures around 100°-100° F would be best. This way, you won’t overheat and end up shivering in the middle of your soak. Spas with hotter temperatures tend to have a thin layer of water at the top that pops out as soon as you get in it, giving you that floating feel which is difficult not to have.



It’s easy for many folks to mistake a jacuzzi and a hot tub. However, hopefully, this gave you much-needed insight into the differences between the two of them.
