spa in a box

The Spa-N-A-Box takes the idea of a portable spa to a whole new level. It’s a cross between a traditional rigid hot tub and an inflatable hot tub that is, in our opinion, brilliant. It’s a luxury model that is built to last for years and it’s one of the ultimate hot tubs you can buy.

It consists of 8 insulated wood-style panels which you join together to make a free-standing octagonal hot tub shell that sits on the ground. Then you place the inflatable hot tub inside the hexagon, fix it into place, and inflate it. In around 20 minutes set-up time, you have a sturdy spa that can seat up to 6 adults in relative comfort – although in our opinion it’s much better to see it as an awesome 3-4 person hot tub

By the way – the panels are reversible, so you can choose your spa to be red-cherry wood or dark walnut! The image on the left shows the red-cherry version.

The Spa-N-A-Box is also one of only a few portable spas that are purpose-built to be used all year-round, even in sub-zero temperatures. So if you are looking for a 4 season inflatable hot tub that is designed to work in the coldest winters, then this could be the spa for you.

Spa-N-A-Box Features & Comparisons

Background Info

The Spa-N-A-Box is made by  ComfortLine, who operate out of Florida and have been in business since 1996, making high-quality portable hot tubs and accessories. They really hit the headlines with the Spa-N-A-Box model, however, which was unlike any inflatable hot tub seen before.

One of the many features we really like about this hot tub is that it is made to survive outdoors in the coldest of winters. From the insulated panels through to the motor-and-massage system power pack with in-built freeze control, it is designed to survive freezing temeperatures, and there are owners’ testimonies saying how they use it year after year through the freezing winters of Alaska and Canada.

We have written an article on using your portable hot tub outdoors in winter which you might find useful. You can read it here: 4 Season Inflatable Hot Tubs (opens in a new tab).

The great thing about the octagonal shell of panels is that they are strong enough for you to be able to sit on the side of the hot tub without worrying about it collapsing.  This also makes it especially great for those who need assistance getting in and out of the spa.

The Spa-N-A-Box has an inflatable lid which adds to its insulation.

The rigid surround panels are 2 inches thick, and they are vacuum-sealed to help insulate the hot tub and keep the water hot. Add in the thermal ground mat, the insulated inflatable lid, and the insulated cover, and you’ll find the water stays really hot overnight without you having to turn on the water heater the next day.

When you do need to heat the water, the Digital Control panel is on the side of the hot tub. The maximum temperature the heater will heat your water up to is 104F, which is the maximum temperature of all portable hot tubs.

The Digital Control panel also controls the water jet massage system, so there is no need to leave the luxury of the water in order to get the full benefits of your Spa-N-A-Box. The massage system is super-powerful, consisting of a ring of 127 air bubble jets at the bottom of the hot tub, which are powered by ComfortLine’s unique Turbo Wave massage system.

Setting up Your Spa-N-A-Box

The Spa-N-A-Box comes in two boxes. It is quite easy to set up, and takes around twenty minutes. We strongly suggest you watch the video below before you set up the Spa-N-A-Box for the first time, as this will make it easier and save you time.

When you have the hot tub set up, fill it with water using a garden hose, and turn on the water heater. It takes about 24 hours to heat the water to the maximum of 104F, depending on the water and air temperatures.

Some people who are new to inflatable spas wonder if 104F is hot enough – but we can assure you that it truly is, and that you’ll be delighted by how hot and relaxing you’ll find it when you get into your hot tub.

While the water is heating up, be sure to put on the inflatable lid and the cover. These add to the insulation and prevent heat from escaping into the air. They also cut down on heating time and save you money.

To jump-start the time it takes to heat the water, you can do what many hot tub owners do, and that’s fill their spa with hot water from their faucet.

It is also possible to set up your Spa-N-A-Box indoors, as long as you have a suitable room. For advice on doing this, you might want to check out our FAQs, which opens in a new tab.

Enjoying Your Spa-N-A-Box

The Turbo Wave massage system is super-powerful.

Once the water is at your desired temperature, simply slip off the cover and lid, and slide into the warm water. Then turn on the Turbo Massage system and enjoy your all-over massage. With the Digital Control panel on the side of the tub, there’s no need to get out of the water.

You absolutely do not need to buy anything else in order to enjoy your Spa-N-A-Box. However, down the line you might decide to add a few extras to enhance your spa experience, such as a floating drinks tray, waterproof Bluetooth speaker, or cushioned headrest.

The beauty of the Spa-N-A-Box – as with all other inflatable hot tubs – is that you do not need to buy your extras from the company that makes your tub. There are a wide range of extras out there and they will fit the hot tub you decide to buy.

One thing you will need to buy, though, is some hot tub chemicals. If you’re newbie, or uncertain about this area of owning a portable hot tub, we have a range of useful articles to help you. A good place to start is with our article Everything You Need To Know About Hot Tub Chemicals (link opens in a new tab).
