What is an Inflatable Hot Tub?

An inflatable hot tub is a compact hot tub with soft surfaces. As its name implies, it needs to be inflated using air in order to work. Inflatable hot tube are often made with some type of PVC that provides it with structure and integrity.

As such they are commonly called portable spas, inflatable spas or portable hot tubs.

These types of tubs are a smaller, more affordable alternative to permanent or in-ground hot tubs. Because they can be inflated and deflated, you can move them more easily than the larger hard-sided tubs.

As with regular hot tubs, they are filled with heated water. Their main purpose is for hydrotherapy, enjoyment and relaxation. They are designed to let you enjoy the experience you get from a Jacuzzi or spa.

  • Due to the limited power from the 120 volt line, their features and temperature are also limited. Typically they give you temperatures between 40 and 104 degrees. In addition, the material used for the tub also causes it to lose heat. Permanent, hard-sided hot tubs are able to reach higher temperatures.
  • Inflatable tubs aren’t as durable as hard-shelled hot tubs. And, they can be punctured. Though it takes a lot of pressure to do so.
  • Many don’t come with a true Jacuzzi feature.

Choosing an Inflatable Hot Tub: Buying Guide

Here are the most important things to consider when choosing an inflatable hot tub.

1. Size & Where You’re Placing It

Choose one that fits the number of people who are going to use it. Most inflatable tubs start at 4 people, though there are some brands that make smaller models. With these types of hot tubs go one size up if you want more room.

Typically, 4 person tub will fit 4 average sized individuals almost side by side. So, if you want more free space go a size up.

2. Construction and Materials Used

As far as use and durability goes, this is the most important. You want something that won’t puncture easily. And, is supportive enough to last a long time.

Most inflatable tubes use PVC or layered vinyl. The good news is they also reinforce the walls with other materials including nylon and polyester. Different brands will use different materials.

Reinforced I-beams are also a great feature to look for. They give your tub more stability. And, make them stand up sturdier. This lets you lean on the walls without them giving way.

3. Number of Jets

How many jets you choose will depend on your preference and budget. You’ll often find units that come with 120 to 140 bubble jets. These line up on the bottom of the tub. And, they blow air into the water from the outside.

The more hot tub jets there are, the more bubbly the water gets. And more importantly, soothing your massage is. More jets also means they cost more.

Do note that the jets installed in inflatable hot tubs draw air from its surroundings. As such, when the temperature drops, it will take more time to get hot since cooler air is being blown into the tub.

4. Filtration and Treatment System

Don’t forget to check the filtration and treatment system. Like swimming pools, these are an important part of personal hygiene. After all, you’ll be soaking in the water for a long time.

Your tub should come with a filtering system. This will keep the water clean and get rid of dirt and debris.

Smaller, more affordable units will come with standard filter and treatment. But, higher end units often have extra treatment features as well. These include salt water treatment like those in salt water hot tubs, and hard water treatment.

5. Heating System

As mentioned earlier, an inflatable tub’s power source has its pros and cons. It uses a standard 120 volt outlet which makes it convenient. Plus, it saves you on electricity costs.

The downside it is delivers limited power. This translates to the tub maxing out at a maximum of 104 degrees Fahrenheit. That’s plenty hot. But, there are a few people who want hotter temperatures. Unfortunately, inflatable hot tubs aren’t going to be able to deliver more than that.

The other effect of the limited power is it takes longer for the tub to warm up. In general, you’ll see temperature rise at 2°F to 3°F per hour. This means, it takes quite a bit of time to get your tub up to temperature.

6. Don’t Forget the Cover

These are very important. It takes a while to fill the tub. A 4 person inflatable tub uses roughly 200 gallons of water. This takes time to fill.

Placing a cover over the tub when it’s not being used prevents leaves, dirt, and insects from getting in there. It also helps keep the water clean for your next use.

Additionally, hot tub covers protect the inside of your tub from objects.
