Point to note:

What is a Best Four Person Inflatable Hot Tub?

People often get confused by the manufacture’s quoted capacity. A 2-4 person capacity for example does not have to make you feel as if it is too big and only works well for 2-4 people only! What it means is that it can fit four people comfortably but we all know for a fact that “the lesser the better”. Incase you are buying a spa for only two people, let the quoted capacity not discourage you because two people will enjoy even more since there will be more utility space in the spa.

We looked at all the small spas in the market below 6feet diameter or width which is the perfect size for one to two adults to seat relaxed while their feet are stretched out comfortably and we shortlisted the best ten that we know are worth your money.

Background on Best Four Person Inflatable Hot Tubs

When inflatable hot tubs were new in the market, people treated them like mega paddling pools for children than spas. Things have evolved since and manufacturers have invented ways to design spas with strong, walls andadequate depth enough to hold large quantities of water and can support those entering the spa.

As time went by, manufacturers improved the size and started making even bigger spas. Today, we have big spas that can hold up to a maximum of eight persons in one soak.

Presently, technology has improved, and grown quickly covering even the small spas. That is why you will find more superior spas in the market now than there were before. They are durable because of the strong materials used to make them and posses superior features.

Factors to Consider When Selecting an Inflatable Hot Tub for Four People

To be sure you get the best small spa that meets all your needs;you must put a few factors into consideration.The most obvious factors include; the cost of the spa, durability, features and customer review. There are other factors that might not be apparent, but are vital in a spa that functions optimally.

The main factors include:


The prices of small spas vary form one manufacturer to the other based on the models and features. These prices can be obtained from Amazon. Com. The prices range from budget models that cost a few hundred dollars to the luxurious ones that are relatively pricy.

Budget models include: Go plus 4 person and Lay-z Miami while Luxury spas include: spa Luxury exotic

There’s a wide range of prices in small blow up hot tubs, as you can see over on Amazon.com. These range from budget models costing a few hundred dollars, like the Lay Z Spa Miami and the Go plus 4 Person, up to luxury hot tubs such as the M-Spa Luxury Exotic. We also have top of the range spas that come with luxurious features and superior accessories giving the traditional built-in hot tubs a run for their money. An example of such spas is the MSpa Elite Reve jet. It comes with 118 bubble jets just like the ones in all other inflatable spas, but it has additional four adjustable hydro jets like the ones found in in-built spas.

Whichever your taste is, be rest assured that any selection from our top best list is a good selection.


All the small spas in the market currently, measure about 70 to 71 inches across regardless of their shape. Thisis spacious enough for a 6-foot person to seat and stretch comfortably.

Other measurements to bear in mind include:

  • Depth of the hot tub
  • Inner dimensions
  • Surface where the spa will be placed once inflated.

Small hot tubs range in depth from 26″ to 28″. Those extra two inches that some models providelike MSpa Camaro, do not seem much, but they allow you toenjoy a deeper soak.

What this means is that a model with 28 inches deep will comfortably accommodate two adults and both of them have the water come up to above their shoulders as they lean against the walls of the spa. With a depth of 26 inches however, two people can still sit in the spa the same way but the water will not go above their shoulders.

Inner dimensions

Modern day bath tubs are constructed using sturdy material and technology making them more durable and comfortable. The inner walls are comfortable to lean on yet strong enough to support the weight of those leaning on it without giving in to the weight and pressure.

Internal construction of the small spas is about 10inches thick. When a small spa is said to have a diameter of71inches, this is just but the overall external size. The inner seating place measures 20inches less than the overall diameter which comes to about 51inches.

Below are various dimensions of different models of small spas:

Whichever place you decide to put your spa, ensure there is sufficient space to facilitate easy access in and out of the spa, and moving around the spa.  You can place it against one side of a wall or both sides for square spas, because walls act as insulators hence saving on energy.

If you decide to put it against the wall then ensure it does not rub the wall which could lead to cracks and or leakages that may in the long ran weaken the wall.

As a basic guideline, we suggest that you leave a couple of feet on all sides of your spa. A small hot tub that measures less than 6 feet across, will occupy a space of about 10 feet by 10 feet.

Air/Hydro jets

Most small hot tubs these days come with a very powerful massage system.

As technology improves so has the massage systems of small spas improved. Many of the reviews on marketing sites like Amazon give very positive feed backs on the massage systems of the small spas. New owners of small spas are more delighted at the impressive massage systems in their new spas

The main features that determine the strength of a massage system are:

  • Number of air/hydro jets
  • Power of water flowing through the jets.

All inflatable hot tubs have the air jet system as a series of holes around the bottom of the walls of the spa. When the massage system is turned on, air blows through the holesproducing streams of bubbles that offer you an overall massage experience. The power of thebubbles being produced is largely dependent on the water pressure that is pumping the water through the holes.

Note; having more air jets does not automatically translate into having a better massage system! The jets must be backed up with a powerful water flow.

As a rule, the more cash you pay for your inflatable spa, the better the massage system is!Because it means that the spa’s water pump is more powerful. For more superior spas like Mspa Elite Reve jet, you will get additional hydro jets as well that are powered by a strong water flow.

The following is a table that shows the number of jets for each of the best ten small spas selected. We have also rated the spas based on how powerful the massage system is.

Everyone wants to invest in a product that will serve them for a long time. Once you buy your inflatable spa, you will be using it from time to time and this will subject it to wear and tear. That is why durability is necessity. All of the ten best small spas that we selected are durable and strong enough to match your demands. This has been necessitated by two factors:

  • Inner construction of the spa walls.
  • Materials used to construct the spa.

Inner construction

The internal construction of an inflatable spa makes the walls sturdy and durable, yet allows them to remain very comfortable at the same time.

Nowadays, the internal construction of all hot tubs has been reinforced, giving the spas more strength to hold securely the hundreds of gallons of water. The strong walls can withstand the weight of those climbing in and out of the spa. The walls are comfortable and steady enough for people to lean back without them buckling.

Inside the walls of every blow up hot tub these days, there is a reinforced internal construction which gives the hot tub the strength to securely hold hundreds of gallons of water. The walls can cope with several adults climbing in and out of the tub, even allowing them to sit on the walls without them giving way or even buckling. At the same time, the walls remain comfortable to lean back against and relax. All this is made possible by use of I beam steel construction technology which many manufactures have adopted to construct inflatable spas.

The I-Beam construction can be used vertically and horizontally, by use of an internal PVC (Polyvinyl chloride) structure that makes the walls of the spa strongenough but still flexible to sustain the demands of daily use.But they also stay flexible enough so that the hot tub is comfortable.

The hot tub materials

Just like their interiors, most inflatable spas have strong exteriors. Various technologies have been adopted when it comes to the manufacture of the outer layer of the spas with the common one being the Tri tech technology (three layer covering)whereby a layer of polyester mesh is put betweentwo layers of PVC. An example of a small spa with this exterior is the Go plus inflatable spa though one of its layers is an industrial foil that is strong enough and a good insulator too.

Superior inflatable spas like those manufactured by MSpa Company have even stronger covers. Examples of those we selected are the Mspa Elite Reve jet and MSpa Super Camaro. They boast of high quality, durable and are made of up to 6layers of laminated PVC.

Water capacity

By being small, the small inflatable spas do not need a lot of water thus making them more advantageous as compared to the large spas. Some of the advantages are:

  • They heat up faster – less energy consumption
  • They are cheaper to maintain heat.
  • They are easy in maintaining the hygiene of the water
  • They drain easily during emptying the spa.
  • They weigh less-Flexible to work with on any space.

Note; Water capacity of an inflated spa fills up to 80% of the spa’s maximum capacity so as to allow the water level to rise when people enter the spa, as well as for the bubbles to build up once the massage system is switched. This way we prevent spilling of water from the spa to the surrounding surfaces especially if you have placed the hot tub indoors.

For every inflatable spa we selected,they each have a minimum and maximum fill-line inside of each spa. It is therefore recommended to fill up to the minimum fill-line when filling for the first time. This to allow you know how much the water rises once you get in the spa as well as when the bubble system is put on.

After using the spa for a couple of times you will thereby decide if you can increase the level of water or just work with the minimum fill –in line.

The weight of the Spa

Inflatable spas carry a lot of weight especially after they have been inflated and filled up with water. One gallon of water weighs 8lbs, which translates to about 210 gallons for a small spa like Goplus for four persons. If we combine the water weight and the weight of the spa, we are talking of 2000lbs, and this is quite something yet we have not factored in the weight of those who will be soaking in the spa.

It is obvious that once the spa is filled, it might be too heavy to be moved to another place. It is therefore advisable that you ensure it is put in a firm surface, with easy to access space before filling it with water.

Incase you prefer putting your spa on a deck, Check the weight first and be sure your deck can support the spa’s weight comfortably. Following the customer reviews on Amazon, those who place their small spas on decks have either reinforced it with six by six pieces of timber or even with car jacks for other people.

If you prefer it indoors, likewise you must consider its total weight. If you are using a concrete floor then there should not be an issue as the surface is firm enough. If you are in an apartment, it is advisable to seek the advice of an expert to be sure the floor can comfortably take up that weight.

The following table gives you a guideline on water capacity at 80% andweight of each spa when filled to the maximum fill-line.

Set up and Heating time

The time it should take you according to most manufacturers of small spas;  from theminute you take your spa out of the box to when you inflate it, with allcables connected and it is now ready to be filled with water is about 10-20 minutes.

For those doing this whole procedure for the first time, it might slightly take you longer than 20 minutes and take you about 45minutes to 1hour.

Ensure you go through the manual comprehensively before opening your spa for installation to avoid any mistakes during installation

After installation is complete, it takes between one to two hours to fill in the water. This will highly be dependent on the water pressure from your faucet.

Once the water level is at the minimum fill-in line, you should cover the spa then set your desired temperature on the control panel. For small spas just like large ones,the maximum water temperature is 104F.

The water in the spa heats up at the rate of 3-4F per hour. Meaning that, it will take up to 24 hours or more to heat the water in your spa, depending on the starting temperature and the surrounding air temperature at the time of heating.

The prolonged period has prompted many people to fill their spas with already heated water in order to reduce the heating time.

For this reason, many people fill their hot tub with hot water, straight from their faucet, in order to speed up the heating process.

One thing you must not do, however, is fill your hot tub with boiling water as this can damage the inner lining of the spa.

The following table shows you the time it takes to heat up water in a small inflatable spa that carries around 200 gallons of water.

In order to know the starting water temperature, turn on the filter system on your spa for a minute and it will show on your digital control panel.
