What is a hot tub?

A hot tub is a type of pool of many different sizes that can be used indoors or outdoors. This product has common use in SPA, clubs, hotels and motels as it works for leisure, relaxation or hydrotherapy.

Another popular name for a whirlpool bath is Jacuzzi or ofuro. These structures have jets that favour the practice of hydromassage.

Usually, ordinary bathtubs are not able to hold more than two people. Whirlpools, on the other hand, can hold up to 8 people, depending on the model.

Whirlpool bath water should not be changed after each use. For daily reuse, it is necessary to use a hygienic method similar to pool care.

There are whirlpools which have a heater to keep the water hot. This type of heating is indispensable for using the hot tubs in the colder times of the year.

What are the advantages of a Hot Tub?

Like almost everything in life there are also advantages and disadvantages to using whirlpools.

As a positive, we can highlight that they can be installed or inflatable, allowing the use inside and outside the house. And of course, the advantage of relaxing with massage jets is the highlight of this product.

As a disadvantage, it is worth mentioning that the maintenance can be a little expensive, and also that it increases the electrical consumption, since to work it is plugged into the outlet. Learn about the pros and cons in the table below:

  • It is possible to use inside or outside any property
  • There are jets to massage
  • In some versions fit up to 8 people
  • It does not allow the use of common shampoos or soaps
  • It requires a little expensive maintenance
  • It needs to be plugged in to work

Hot Tub or regular bath?

This question has probably already come to your mind: Why buy a whirlpool bath when ordinary bathtubs are cheaper?

Obviously they offer different functionalities. The main differences are in the capacity, a standard bath is usually much smaller and more limited, as it is exclusive to indoor environments.

In addition, the whirlpool bath has the advantage of having the jets of relaxation, and can be used outdoors too. Not to mention that they are bigger.

Check these and other differences between the two versions in the comparative table below:

Whirlpool bathtub Regular bathtub
Use Indoor or outdoor environments Indoor environments
Jets for relaxation Yes No
Shampoo and common soaps Not allowed in the hydro baths with wet jets Allowed
Capacity From 1 to 8 people Maximum 2 people
Use of water It is not necessary to eliminate the water for a new use It is necessary to eliminate the water before a new use

What are the types of jets in the whirlpool bath?

The secret to a good whirlpool bath lies in the jets that are useful for relaxing your body. They are not all the same, so it is important to know the difference between them. A whirlpool bath may have one or more jets of different types:

  • Directional turbo jet: It offers an output of water together with air in some parts of the body that need more relaxation.
  • Turbo-jet: With pulsating and rotating effect, this feature changes the mixture between air and water. Many people believe that these versions of jets are the most relaxing in the world.
  • Small jets: Also known as mini jets, these productions have an additional water flow. They are true complements to the larger jets.
  • Air bubble jets: This is one of the features that are part of most hydros on the market. This jet releases small bubbles of air into the water to generate an extra relaxing sensation.

What size to choose?

One of the biggest variables of bathtubs is in the size. If you have a spa or just want to get a lot of people together in the hydros in your home buy the large structures.

When the use is for just one or two people, in a more intimate way, then the smaller choices are better. By choosing small bathtubs you can save a lot on the purchase.

The prices get higher as the capacity of people increases, but this rule does not apply to all models. After all, there are smaller versions with more special jets that cost much more than the large, basic models with just one type of jet.

The size of a whirlpool bath is measured as follows:

  • Length: It varies between 80 and 300 centimeters, but it can be longer;
  • Width: It can go from 80 to 200 centimeters, or more;
  • Depth: This is one of the most important aspects in measuring the whirlpool bath. Many people buy the product just thinking about length or width, forgetting how deep the version can be.
    The depth measurement of the hot tub should consider length, width and gallons of water. If the product is going to be used by children it is best not to buy a very deep edition.
    The gallons of water that can fit in a hot tub can range from 300 to up to 1,000, or more.

Fixed or mobile hot tub?

There are two forms of whirlpool baths: fixed or mobile. The heavier structures should only be in a fixed place, usually in the bathroom or in a reserved room in a SPA.

The fixed whirlpool bath is heavier, composed of ceramic and metal. These versions are resistant and have a structure capable of working with several jets.

A disadvantage is that moving the heavy bathtubs does not represent a very easy task. Installation also requires connection to plumbing, which requires a cost of time or money.

If you are still not too sure where to install, it is really best to choose mobile, inflatable or solid bathtubs. Check out their main features:

Mobile and inflatable

The advantage is that you can take these PVC and plastic products to different indoor or outdoor locations. You can fill the inflatable bathtub in a few minutes using air. The water filling happens with a hose.

This hot tub edition also has heating and relaxing jets. The downside of the inflatable product is that it doesn’t look very professional for use in a spa, for example.

Mobile and solid

This type of hot tub is also called an ofuro, which is very popular in Japanese homes. It is a solid structure, meaning that you don’t have to do the work of filling it with air.

In this version there is an intermediate weight. This product is not as light as an inflatable tub, but also less than a metal and ceramic tub.

In some versions these whirlpools are made in the shape of a wooden barrel. Structures of this size make the decoration of the spa more rustic or natural. The product also has hydromassage jets and heating.

In the following table you can learn a little more about the differences between fixed or mobile bathtubs:

Fixed whirlpool bath Inflatable whirlpool bath Solid and mobile whirlpool bath
Use Indoor locations Indoor and outdoor locations Indoor and outdoor locations
Flexibility Low High Medium
Resistance High Medium Medium
Material Ceramic or metal Plastic Wood, ceramic or plastic
Jets Moist and (or) air Moist Moist
Water filling Without external hoses With external hoses With external hoses
Regulation of water temperature From low to high From low to medium From low to medium

How much does it cost?

The brand is one of the factors that influence prices, but there are other things that can also make bathtubs more expensive or cheaper, such as the type or number of jets, size, material, litre capacity and water heating motor.

The versions of less famous brands, with few types of jets and smaller cost an average price ranging from £700 to up to £1,000.

Large whirlpools that have several different jets are perfect products for hotels, motels and 5-star SPAs. These structures have prices ranging from £3,000 to £10,000.

Buying criteria: Factors to compare hot tub models

There is no shortage of good offers on the Internet. With so many different adverts for hot tubs, it can be a bit tricky to choose one, can’t it? Not if you take the following points of view into account:

  • Heating
  • Jets
  • Water pump
  • Waterfall
  • Kits

Below, see the explanation of each of these factors:


If you live in a place in Brazil that is hot almost every day, you don’t have to worry too much about the heating power of the hot tub. Some parts in the country are colder, so they require a very heated hydro.

What defines the heating power of bathtubs is the water heater motor. A heater is one of the most expensive parts of the hot tub. The heating power in these devices can range from 1,000 to 10,000 watts.

Keep an eye on it! The more watts there are in the heater, the better the hot tub’s ability to generate heat in the water.


The number of jets in a hot tub range from 1 to 10 or more. The number of jets is important, especially in larger hot tubs that fit more people.

However, the number is not the only important factor. It is also worth choosing hot tubs with different types of jets.

The best whirlpool baths in the world have many jets of different varieties. There are also cheaper productions with 3 or 4 jets that work well for two people and cost popular prices. Evaluate your need before deciding on a purchase.

Water Pump

Water pumps are important parts for whirlpool baths of different types.

They have the capacity to evolve the power of the water jets, besides allowing a safer use, saving electricity.

The more powerful the water pump, the better the overall characteristics of a whirlpool bath. A water pump in power can go from 5,000 to 15,000 watts.


The waterfall for whirlpool bath is one of the special differentiators to the customers. With the cascade, people in the bathtubs have as a benefit a waterfall similar to the cacheira.

The water outlet opening in the cascade ranges from 10 to 80 centimetres. Another advantage of this accessory is that it oxygenates the water in the hot tub better. As a result you have superior relaxation.

Some structures of this kind even have a led lighting function, the environment becomes more relaxing and romantic. The main lighting colours are: yellow, blue, pink and red.

Normally the brass waterfalls have a 10-year guarantee. The chrome versions, on the other hand, are guaranteed for 2 years, according to the average of the main manufacturers.


There is no denying it. Most of the whirlpools do not allow the use of common shampoos or soaps. They have too many chemicals that are harmful to the functioning of the relaxing wet jets.

To use the most popular whirlpools it is necessary to buy shampoo and soap with special compositions. Add this to the need to treat the water for reuse, and the cost certainly gets a little high.

Don’t forget to investigate whether it is easy to find these special soaps and shampoos on the market according to the characteristics of the tubs you wish to buy.

There are also bath tubs on the market that accept the use of any shampoo or soap. If you are keen on using your favourite cosmetics you should take a bathtub with air jets only.

This was the shopping guide that teaches you how to buy a whirlpool bath without making a mistake. Consider all the information in this text to find the best deals with less cost and more benefits.
