For those seeking a relaxing and therapeutic addition to their home environment, a hot tub is a wonderful choice. But it’s not a purchase to make lightly – there are lots of things to consider when buying a hot tub, from size and features to maintenance costs. This hot tub buying guide will walk you through the important things to think about before splashing out on a new hot tub so that you can make an informed choice.

What Type of Hot Tub Should You Buy?

In-Ground Hot Tub

An in-ground hot tub is a permanent fixture, installed into your garden so that the deck and outside of the tub are even with the patio surface or other ground area. You need a lot of space for an in-ground hot tub so it is best for larger gardens or for those willing to sacrifice some lawn or garden area. Installation costs can be high, but in-ground hot tubs generally offer a luxurious feel with lots of extras.

Above-Ground Hot Tub

Above-ground hot tubs are portable and come with their own platform to stand on. They generally require less space and installation costs, making them a more affordable choice. However, you’ll need to factor in the additional costs of a rigid outdoor cover, which is recommended to help control heat loss and to keep out debris. And you may wish to invest in a nice surround for the hot tub for a cleaner look.


A spa is a term used to refer to hot tubs that offer more than just a hot soak. Extras such as massage jets and aromatherapy systems are common features. Spas are more expensive than standard above-ground models, but they offer more luxury and relaxation.


Seating Capacity

The seating capacity of a hot tub is determined by the number of emitters it contains. Generally speaking, hot tubs range from 4-seaters to 8-seaters, with some high-end models offering even more seating capacity. Depending on the size of your family (and the size of your budget) you can choose a hot tub with the right number of seats.


The number of seats determines the overall dimensions of the hot tub, but even within the same seating range some models are larger or offer more interior space than others. When considering the size of your hot tub, it is important to carefully measure the space in your garden or patio and make sure the hot tub you choose will fit into the allocated area with enough room for seating and movement.



The water needs to maintain an optimum temperature for relaxation, so a combination of electricity and gas is used to heat it. An electrical heater will switch on when the hot tub is first filled up to reach the right temperature, and then maintain it. Natural gas heaters are a more economical option, but bear in mind they require they own dedicated gas line.

Massage Jets

Some hot tubs come with massage jets which let out a stream of water, set at varying pressure. This helps relax muscles and improve circulation, as well as providing a more intense massage experience. As a guide, 4-6 jets can provide good coverage of all body parts, while 8-12 jets will offer a powerful full-body massage.

Lighting and Sound Systems

High-end hot tubs can also come with some fun extras such as coloured lighting, which can be set to pulse or flash in time with music, and sound systems that create the perfect atmosphere.



To keep your hot tub debris-free, chemical treatment is necessary to kill off microbes and fungus. This can be accomplished with the use of pH-balancing chemicals, sanitising substances and mineral dispersion systems.


Filters are essential to keep the hot tub water clean and free from contaminants. Many hot tubs use disposable, cartridge filters that need to be changed regularly. It is important to replace your filter once a month to ensure the water stays crystal clear.


To keep the inside of your hot tub free from bacteria and other contaminants, regular cleaning is needed. Vacuum the interior and clean out the jets with a specific hot tub cleaning solution, as regular household products can corrode or damage the interior.


Runninng Costs

Don’t forget to factor in the cost of running your hot tub when considering the overall cost. For example, electricity or gas for the heater and chemical treatment for the water will both add to your energy bills.


Insurance for your hot tub is not mandatory, but it is always smart to make sure it is insured under your home insurance policies. This can help cover some of the costs of repairs or replacement parts if the hot tub breaks down.
