7 Best Family Inflatable Hot Tubs To Buy In 2021

Don't miss a thing

Published on 07/03/2021

There’s no doubt that we’ve seen a huge rise in people buying hot tubs since the UK’s 1st lockdown and it’s not slowing down!

This increase in demand for inflatable hot tubs, and the relative affordability of them has meant that what was once a luxury item, is now far more readily available in a lot of family homes.

Now, there are a lot of reasons to get a hot tub – sitting under the stars, to help with injuries for example BUT… here at Dadsnet we know first hand that occupying the kids for hours upon hours, almost all year round has to be the #1 reason to invest in one of these hot tubs.

If you top up the chemicals regularly, hot tubs should be far more hygienic than the local swimming pool and with accessories like cup holders, mood lights and cushions, it could feel like you’re on holiday even when you’re sitting in your back garden.

Obviously, the various lockdowns has meant a far larger demand for hot tubs and as a result, there may be stock issues for the products below. If you see a hot tub you like then act fast as they sell out quickly and some have long lead times for delivery.

Here are the family best hot tubs for 2021.

1. Lay-Z-Spa Miami Hot Tub

There are some great extras available, such as a liner repair kit, a storage bag and 2 filters. Intex also have a built-in hard water treatment system, which makes the water gentler on your skin. Some users say this is a little noisy, but in our experience, most of them are.

It really should be a strong contender though, with no less than 100 jets and it can be used all year round. It also comes with a ground sheet that will help with heat loss.

The best thing, however, is that it heats up pretty fast – at between 1.5 to 2.5 degrees an hour.

Is it worth buying a hot tub?

Short answer. Yes – if you can afford it.

Hot tubs have become increasingly popular since lockdown 2020 and sold out rapidly making them very sought after. Because people were unable to leave their homes or go on holiday, having a little bit of luxury in their garden made all the difference. But more than this, it was something to occupy the children.

It’s worth keeping front of mind that hot tubs are a small commitment. The filters and chemicals are necessary add-ons and will need topping up and changing regularly. It’s also an extra sexpense on your electricity costs. This includes having to wait for your tub to heat to its optimum temperature of 40 degrees – anything from 3 to 20 hours, depending on the model.

But there are a growing number of parents who say it’s worth buying a hot tub. And we’re firmly in this camp.

What should I look for when buying a hot tub?

  • Style: Inflatable hot tubs are much cheaper to buy than hard-shell hot tubs but are often not as well-insulated so their running costs can be higher. Inflatable tubs also won’t last as long but they are, however, less of a commitment than hard-shell tubs as you don’t need ground works to have them installed. And of course, they’re a lot cheaper.
  • Safety: You will want a hot tub with a lockable lid, especially if you have young children to make sure they are safe at all times. Most of them do, but it’s worth double checking.
  • How it is heated: Most hot tubs plug into the mains and you’ll ideally need an outdoor plug or locate it next to the house, garage or out building.
  • Shape: Circular hot tubs are more traditional and great if the pump is external as it gives you somewhere to store the pump out of the way in a corner of the patio / decking. However, square hot tubs are growing in popularity as they fit neatly on patios.
  • Dimensions: As well as external dimensions, look at internal too. The secret is to work out the size of the walls – thinner means more heat escapes BUT more space inside. So it’s a trade off.
  • Capacity: If you’re looking to fit 4 people with a good amount of extra room, then look for a 6-person hot tub. The average sizes are 2 to 4 people, 4 to 6 people and more than 7 people.
  • Insulation: A well-insulated hot tub will keep the water hotter and will keep your heating costs down. Ground sheets and external covers can be bought separately.
  • Cost: It’s not just the initial outlay you’ll need to factor in when buying a hot tub. You need to consider the cost of chemicals to keep the water clean, spare filters and of course, for mains-powered hot tubs the electricity. The bigger the hot tub, the bigger the expense. It can cost from £1 to £7 a day to heat your hot tub depending on how well your tub is insulated.
  • Accessories: In our opinion, you don’t need any accessories because most of them, you’ll have at home already in various forms. A cup holder for example… maybe just a table next to the hot tub?

What’s the lifespan of a hot tub?

Well, this depends whether you have children who will burst it with a piece of Playmobil or not… (Yes, this happened to me…) But, how long a hot tub lasts depends on the quality of the materials and how well it’s looked after. Most hot tubs come with a minimum warranty of 12 months.

You can expect to get between 2 to 5 years’ use out of an inflatable hot tub.

How do I clean my hot tub?

When you first use your hot tub, you’ll need to ‘shock’ the water with chemicals before checking your hot tubs chemical and pH levels.

There are two ways you can do this. You can either use chlorine, which is available in tablet or concentrate form, or bromine, which is available in tablets or powder forms.

If you use chlorine, you need to check the pH is between 7.2 and 7.6. If you use bromine, then it should be between 7.0 and 7.4. You can buy 50 strips for under £5 from Amazon. Test your hot tub water at least 2 to 3 times a week. You should change the water every 2 to 3 months as a minimum.

When you change the water, you should empty the hot tub and clean out the pumps too (if it has them).

Hot tub filters need to be changed at least once a year.

Which is the best hot tub to buy?

Well, it mainly comes down to personal preference but in our experience e, one of the best hot tubs to buy is the Lay-Z-Spa Miami Hot Tub. It’s affordable but tough & durable for the kids to use and can seat up to 4 people.
