Hot Tub Buying Guide

Updated: Nov 18, 2021

Last year, a garden hot tub jumped to the top of many people’s wish lists; with many wholesale hot tub supplies distributors struggling to keep up with demand. Buying a hot tub isn’t just a pricey water feature.

They can provide a variety of health benefits, with hours of home relaxation to you and your family. As wholesale hot tub supplies experts, Aqua Warehouse hot tub buying guide reveals the best way to purchase a luxury spa; outlining different types of hot tubs, typical prices and sizes.

What to look for when buying a hot Tub

Why do you want a hot tub? Is it because you have just had your first experience and now you are hooked?

Assuming you have already read our other guide ‘Hot Tub Location & Installation’ you have now decided on the perfect location whether inside or out and now you have some questions, all of which could affect the final price.

Some of the most important aspects are the type of tub, size, accessories & safety issues.

Choosing a hot tub shouldn’t be difficult after all it’s just a spa bath right? Not exactly, and after reading this, you will realise it’s better to make your right choice first time, by understanding all the options available to you, as with every choice there is a noticeable price tag attached.


Most hot tubs come in a selection of sizes. There are three industry-standard hard shell hot tub shapes. These include:

  • Small 163cm - 213cm L x 165cm - 207cm W x 74cm - 89cm H

  • Medium 201cm – 241cm L x 195cm – 241cm W x 84cm – 98cm H

  • Large 213cm – 274cm L x 213cm – 280cm W x 91cm – 97cm H

Please note, these measurements are not set in stone and may vary depending on the brand. Inflatable spas do not have a standard set of sizes. Instead, they typically categorise the size of the hot tub by how many can it can seat. This usually ranges from 1-2 up to 6-8 people.

Our hot tubs for sale range from £3,500 to over £15,000 and can comfortably hold up to 8 people.


Also the shapes can vary from circular, square and even triangular which are designed to fit in a corner. So you consider how many people will want to use the hot tub at any one time, and the space available e.g. a large open circular decking covered with a gazebo, would look brilliant with a sunken circular hot tub with coloured lights on a summer evening, and even more spectacular in the winter frosts and snow.

Remember, it’s important to check for key hot tub accessories and features. As a wholesale hot tub accessories supplier, we recommend checking all of the below as well.


The number, type and positioning of jets will vary with each hot tub. Paying more will typically allow for more jets and customised positioning.


Better insulated tubs will keep the water warm for longer and ultimately reduce energy usage. 100% full foam insulation is considered one of the best.

Hot tub covers

Did you want to keep the cleaning to a minimum, and keep the water warm?

In which case you will need a lid, or a cover. Plus if you want it to be easy to take on or off, a simple hot tub ‘lid lifter’, is the perfect solution for you.

A cover for spas is essential to ensuring its longevity. We also recommend checking out

the Covana cover, for those who want to add a luxurious feel to their spa set up. These enclosures are great for rainy or windy days and most can be taken down easily if you want to sit in the sun.


Perfect for night-time dips. Lights should come as standard with hard-shell tubs but will be a

special addition to inflatables. You can also buy floating lights as an accessory.


After lighting and covers, anything else may be considered as a convenience rather than necessary i.e. steps, spa pillows, sound system (dvd), additional jets, cleaning wand, scents, bar kit, gazebo. However, if you can cut down the size of the hot tub and not buy one with space you will rarely use, you will have saved some cash and can buy more ‘extras’.

Safety in a hot tub

Young children should never be left unsupervised in or near a hot tub for obvious reasons. Whilst this does a matter of common sense, accidents can happen to anyone at any age.

Also remember, hot water can make some people feel a little faint, so even adults need to be carefully watched if they feel affected by the heat.

If you are going to use your hot tub for garden parties, bbq’s etc where there is going to be food and drink on offer, it is advised that food should not be eaten in the hot tub, and drink in real glasses should NEVER we served. If a glass breaks in the hot tub, it is virtually impossible to find the shards of glass to remove. Apart from injuries to your friends, there is also the inconvenience of having to totally drain the hot tub to clear it and sanitise after injury. There are some very good quality plastic wine, beer and champagne glasses available.


In conclusion, what to look for when buying a hot tub depends on your budget, available space and which accessories your need.
