Hot tub deals: the best buys for 2021

The best hot tub deals now on

By price: Low to high

A 4-person hot tub for just £255? Yes please!

Wave Atlantic 2-4 Person Inflatable Hot Tub | £455 £255 (save £200) at Homebase
For a 4-person inflatable hot tub, Wave's Atlantic model is a good size, offering an 800L water capacity. The water heats up to 39˚C and 105 massaging air jets are on hand to offer an underwater massage. It also now has £200 off for a limited time only at Homebase, making it our top sale buy at just £255. Bargain! 

CosySpa Inflatable Hot Tub Spa

CosySpa 4 Person Inflatable Hot Tub | £329.99 £299.99 (save £30) at Amazon
This affordable hot tub can seat up to four people at one time, and for a 4-person hot tub the 800L water capacity plus 130 bubble-creating air jets is pretty impressive, rivalling many inflatables that are marketed as 6-person spas. The basic model is currently a great price in the sale, although you can upgrade to a 'comfort' package to get drinks holders, headrests and an inflatable cover too.

CleverSpa Florence Hot Tub
Or, for extra legroom, this 6-person hot tub for just £300 is a great deal

CleverSpa Florence 6 Person Inflatable Hot Tub | £560 £300 (save £260) at Homebase
The best priced 6-person hot tub we've found, the 1000L CleverSpa hot tub has enough room for six people to enjoy themselves comfortably, with 130 massaging jets in total and '365 freeze guard' so you can leave it on your patio all year round. It also comes with an insulating top cover to retain heat when the hot tub isn't in use.

Lay-Z-Spa St. Lucia 3 Person Hot Tub

Lay-Z-Spa St. Lucia 2-3 Person Inflatable Hot Tub | £310 at B&Q
Even without it being in the sale, this hot tub is still a great price for one of the inflatable hot tub world's leading brand names. It's small, with just a 605L water capacity, but if there are just the two of you sharing, then this bargain hot tub delivers the outdoor spa experience at a very reasonable price. 


Wave Atlantic 6 Person Inflatable Hot Tub | £520 £320 (save £200) at Homebase
This time in blue, Wave's 6 person Atlantic hot tub offers a 1000L water capacity with 39˚C water heating and 130 massaging air jets. Just like the 4-person Atlantic model at the top of this list, the 6-seater has £200 off for a limited time only at Homebase, making it almost as good a deal as the 6-seater Florence CleverSpa.

CosySpa Inflatable Hot Tub Spa

CosySpa 6 Person Inflatable Hot Tub | £529.99 £359.99 (save £170) at Amazon
Such a good deal we included it twice, the 6-person version of the CosySpa hot tub offers a 1000L capacity and 130 air jets. Again the best deal is on the no-frills package, but you can upgrade to get cover, headrests, and, of course, the all-essential drinks holders.

Lay Z Spa Bali 2-4 Person LED Hot Tub

Lay-Z-Spa Bali 2-4 Person LED Inflatable Hot Tub | £450 at Argos
Why would you pay more for a smaller hot tub that isn't in the sale? Well, if you want to add some wow-factor to your outdoor spa experience then this 669L water capacity LED hot tub from Lay-Z-Spa definitely delivers. Perfect for smaller spaces, it features an 81 airjet massage system and a 7-colour LED lighting system so you can set the mood with multi-coloured light effects.  

Lay-Z-Spa Milan 6-Person Inflatable Hot Tub

Lay-Z-Spa Milan 6 Person Inflatable Hot Tub | £699 £475.45 (save £223.55) at Amazon
For the tech-savvy this 916L capacity hot tub is equipped with wifi controls, so you can start the spa waters heating - or even control the two levels of massaging jets - from the convenience of your mobile or voice-activated device. Clever.

The best deals on hot tub everyday essentials

Investing in a hot tub isn't just about the initial purchase, there's also the (less exciting) hot tub maintenance to consider. 

From hot tub water testing kits to chlorine and pH. adjustment packs, it's worth stocking up on the essentials for everyday running whilst they're on offer - or at least at the best price around. 

We've rounded up all the essentials you might need, along with some not-so-necessary additions that just make spa time more fun, below.

Clearwater Chemical Starter Kit for Hot Tub Water Treatment

Clearwater Chemical Starter Kit for Hot Tub Water Treatment | £29.99 £22.27 (save £7.72) at Amazon
It might not be a huge saving, but the discounts on everyday essentials all add up. This popular hot tub starter pack includes all the chemicals you need to keep your water bacteria-free - including 500g chlorine, 700 g pH minus, 500 g pH plus, 500 ml foam remover, 25 test strips and a dosing guide.

Hot Tub Testing Strip Kits

Hot Tub Testing Strip Kits | £11.99 £10.99 (save £1) at Amazon
A pack of 100 testing strips to check your hot tub water for four all-important levels; chlorine, bromine, total alkalinity and pH. Just dip the pool testing strip in the water and within 60 seconds you'll be able to compare your test strip to the colour chart on the bottle to read your levels.

DeeprBlu LED Garden Light

DeeprBlu LED Garden Light | £7.99 at Amazon
Designed to float in the hot tub, bath or swimming pool, this colourful waterproof LED light also looks fantastic dotted around the garden at nighttime. It can be set to one colour for a continuous glow or the multicolour mode for a shifting colour display - the perfect way to add illuminations to your hot tub on the cheap! The price is for one tennis ball-sized globe light, but we think it's worth stocking up on a few for a more dramatic look.

Black Friday hot tub deals

Often hailed as the biggest shopping day of the year, Black Friday falls on the last Friday of November, which this year means Black Friday is on Friday 26th November 2021. 

The term Black Friday originated in the US to denote the first day following Thanksgiving when retailers would cut prices to draw holidaymakers to shop their store's sales. Driven by global brands, the price-slashing event soon crossed the pond, and now Black Friday - closely followed by Cyber Monday - has become one of the UK's biggest consumer extravaganzas, rivaling traditional Boxing Day sales. 

The event has also spread to encompass more than one day, with many retailers starting their 'Black Friday' events earlier and earlier to try to get ahead of the competition, and that can mean good news for hot tub deals!

As with any sale, it's important to keep a level head and not get too swayed by the WAS/NOW stickers. After all, anything you don't actually need isn't really that much of a bargain, however well marketed it may be. But, the event does remain a good opportunity to snap up a potential bargain on a big-ticket item - like a hot tub - that you've had your eye on for a while.

You'll find our guide to all the best buys in our Black Friday deals hub, and we'll be updating this page to bring you all the best Black Friday hot tub deals as they're unveiled, so watch this space! You can also find great savings on other big-ticket outdoor purchases on our garden furniture deals page.
