Hot tub deals: the best buys for 2021

The best hot tub deals now on

By price: Low to high

Lay-Z-Spa St. Lucia 3 Person Inflatable Hot Tub | £310 at B&Q
Even without it being in the sale, this inflatable hot tub is a great price. 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. View Deal

CosySpa 4 Person Inflatable Hot Tub | £399.99 £329.99 (save £70) 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.View Deal

A great price for this spacious 935L capacity hot tub

Lay-Z-Spa Vegas Airjet 4-6 Person Hot Tub | £490 £390 (save £100) at Homebase
The Lazy-Z-Spa Vegas offers a whopping 935 litre capacity which means you can fit 4 - 6 people comfortably inside, and there are 140 air jets for a soothing jacuzzi experience. Best of all it's only £390 currently at Homebase, a great deal considering its price elsewhere.View Deal

CosySpa 6 Person Inflatable Hot Tub | £529.99 £439.99 (save £90) at Amazon
Such a good deal we included it twice, only this is the 6-person version of the CosySpa hot tub that 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. Considering this 6-person spa is currently far cheaper than many 4-person alternatives, we think it's well worth upgrading to enjoy more legroom and a more relaxing jacuzzi experience (although admittedly it will mean a bit more water and energy usage to heat). View Deal

CleverSpa Florence 6 Person Hot Tub | £575 at Homebase
Prefer a rattan look? This 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 year-round. View Deal

Lay-Z-Spa Bali 2-4 Person LED Inflatable Hot Tub | £569.50 at Amazon
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.  View Deal

Lay-Z-Spa Milan 6-Person Inflatable Hot Tub | £690 £678.79 (save £20.21) 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. View Deal

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) 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 | £29.99 £24.95 (save £5.04) 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.View Deal

Hot Tub Testing Strip Kits | £11.99 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.View Deal

DeeprBlu LED Garden Light | £12.99 £7.99 (save £5) 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 price is for one tennis ball-sized globe light, but whilst they're in the sale we think it's worth stocking up on a few for a more dramatic look.View Deal
