What size inflatable hot tub do I need?

Put simply, the bigger your hot tub is, the more people you’ll fit in it. But big is not always better.

The larger tubs are generally more expensive, and they take longer to fill up with water, and cost more to heat. So you’re better off choosing the model which best suits your lifestyle.


You need to think about how many people you plan on getting into the hot tub at once. Portable hot tubs range in size from those which fit 2 people in comfort, up to those seating 8 adults or more. So if you’re buying your hot tub as a place of relaxation for just yourself, and your partner, then a 2-person model would be fine. However, you might be better off considering a 4-person hot tub, in case you decide to entertain or have visitors.

A 4 to 6 person model would be perfect for a family, as this has enough space for mom, dad, and the kids, as well as any of your children’s friends.

Finally, if you lead an active social life, and you see yourself having a lot of friends around to enjoy the delights of your new inflatable hot tub, then you’d be advised buying a model for 8 adults or more.

How much space do they take up?

When you think about the size of your portable hot tub, remember you will need some space around it so that you can get in and out easily. One of the smallest quality models is the Lay-Z-Spa Miami Inflatable Hot Tub, which measures 180 cm across in diameter. If you add on, say, 60 cm for ease of access, then you could easily fit this model into a space measuring 2.5 meters across.

The great thing about inflatable hot tubs is that they are portable, so you can set yours up in any suitable spot. Just make sure the ground is level, and that you have enough space around it for access.

Can I set up my inflatable hot tub indoors?

Yes. As long as you choose a room with a solid floor, usually a room on your ground floor, as the water in your hot tub will be quite heavy.  Make sure the room is well-ventilated, of course, as your hot tub does give off steam which will condense.

Also, make sure to place your tub away from plug sockets and valuable items, just in case some water accidentally splashes, or there are drips when you get out.  

What about the electrical supply?

Inflatable hot tubs are inflated, run, and heated by electricity. They come with a long cable which has a normal household plug on it, that you simply plug in to an everyday household socket. So there’s no need for any special wiring or paying an electrician.

Do check that the electrical lead is long enough for you to site your hot tub where you choose, though, as we do not recommend using an extension cable.

How much does it cost to run an inflatable hot tub?

That does depend on the size of your inflatable hot tub, and how frequently you use it.  From personal experience and having read hundreds of customer reviews, you should plan on it costing between $2 to $10 a week., depending on those two factors of size of your portable hot tub and frequency of use.

How much maintenance does an inflatable hot tub require?

Not very much.  Simply wipe the inside of the tub at the water level with a damp sponge, to keep it clean.  If you use a cleaner, do not use an every day household cleaner, as this might damage the water filter and pump.  Instead, get hold of an inflatable hot tub surface cleaner from a site such as Amazon.

How do I keep the water clean?

Inflatable hot tubs come with a water filter system, so you will need to change the filter every few months, although this depends on how often you use your hot tub. You will also need a supply of chemicals which you add to the water, to prevent micro-organisms from flourishing. While your portable hot tub is not in use, you simply put a cover over it, to keep the water clean.

Do I need to buy anything else?

Your inflatable hot tub will come with everything you need to set it up and enjoy it straight away.

Remember, though, that you will need to purchase a replacement filter for your model, as well as some more water purification chemicals,. Our advice is to buy a supply of these when you purchase your hot tub, as it puts your mind at rest knowing that you already have them when the need arises.

Can I use my inflatable hot tub all year round?

Possibly. It depends on exactly where you live, and how cold the winters get.  The bottom line is that you should not use your inflatable hot tub in temperatures below 40F.  That’s because the PVC material the hot tub is made of will become brittle in such cold weather and will quickly perish. If you are lucky enough to live in more warmer climates, however, your inflatable hot tub is suitable all year round.

Is it safe to use an inflatable hot tub if you have a medical condition?

Generally, it is completely safe, although this does depend on your specific condition.  Check out our article on The Health Benefits of Hot Tubs by clicking this link:
