The Best Ways to Maintain Your Hot Tub

There are many reasons why people are drawn to hot tubs. There’s nothing more decadent than the pure relaxation of lying back in hot, bubbly water. But as well as bringing a touch of luxury to the garden, they also have fantastic health benefits — making them an affordable option for those who require regular hydrotherapy or stress relief.

Although the commitment to cleaning and maintaining the hot tub is relatively small, it can be off-putting to those who are in the dark. This guide shines a light on the questions surrounding the cost of maintenance, as well as the right way to maintain a hygienic tub.

How much does a hot tub cost to run?

One of the many benefits of inflatable hot tubs is that the upfront investment is low. However, the costs don’t end after your initial purchase. Inflatable hot tubs are portable, meaning that they don’t have to be plumbed in — another saving in the initial set up costs. You will, on the other hand, need to spend money on the water that it takes to fill the tub, the electricity that it takes to heat that water, and the chemicals that are used to keep the water clean.

All in all, we estimate that it could cost anything between £10 and £40 a month to run an inflatable hot tub.

Getting the best from your hot tub

It’s impossible to create a space for relaxation without first covering the basics. Hot tub hygiene will not only dictate your level of enjoyment but it will also ensure that you can unwind safely.

As mentioned above, hot tubs need power to heat the water. One of the best ways to make the most of your energy usage is to ensure that the tub is adequately insulated. Not only should you make use of the padded hot tub cover, but you should also place a mat or outdoor rug underneath the tub to prevent cold creeping in from the ground. If you don’t expect that you’ll use your hot tub again for a few months, you should drain it, clean it and store it away safely to ensure that it doesn’t suffer unnecessary weathering. Small changes like this ensure that you can relax with peace of mind.

How to keep your hot tub clean

The high water temperatures of a hot tub are the perfect environment for bacteria to flourish. So if you’ve noticed that your spa water is cloudy or that the tub is looking dirty, it’s time to give it a good clean. Our hot tub maintenance schedule shows you exactly what you need to do and when.

Clean hot tub filters bi-weekly by soaking them in warm soapy water and rinsing

Depending on the density of use, replace filters every few weeks (look out for hard or discoloured filters)

 
 

Check the pH balance of the water with test strips, look for a pH level between 7.0 - 7.6

   
 

Sanitise the water by adding quick dissolving chlorine

   

1. Chemical water treatments

It’s important to constantly maintain the water in your hot tub, whether it’s by simply emptying and cleaning the filter or re-dosing with chemicals. Due to ever-changing pH balances within the water, most hot tubs will need a daily top-up of chemicals, so be sure to follow a weekly cleaning schedule. If a normal dose of chlorine hasn’t solved the issue, you should consider adding a shock dose to the tub.

Chlorine

Chlorine is one of the more popular chemicals used to clean hot tubs, keeping the tub bacteria-free. Quick dissolving chlorine is available in granules or tablet form, designed for hot tubs. Around two hours after use, check the pH balance of the water to monitor the chlorine levels. If the water was particularly dirty, you may need to add more chlorine to the hot tub.

What is a shock dose?

A shock dose is a highly concentrated dose of cleaning chemicals added to your tub. This re-establishes hygienic water in the hot tub by breaking down organic waste and contamination. Add 5-10 times more than the recommended amount of chemicals to your spa to do this.

2. Cleaning the filters

The filters are an important part of your hot tub, as they work to trap dirt and debris to prevent clogging the water pump. These filters should be cleaned after every use to ensure that your hot tub is kept in full working order, and should be replaced with new ones every few weeks — especially after they have become hard or discoloured.

Always have a spare hot tub filter available so that you can use the spare whilst cleaning the other. After removing the filter from its housing, rinse it with a hose. Allow it to dry thoroughly and then shake to remove any loose particles. Then, immerse the filter in a bucket of clean water and add 1 litre of filter cartridge cleaner for every 20 litres of water. Soak it for at least 8 hours, remove it from the solution and rinse with fresh water. Make sure you allow it to dry before replacing into the hot tub.

3. Clean the hot tub’s surfaces

How often you drain and deep clean the hot tub will depend on how often it is used. As a general rule, we recommend draining it every three months to ensure that it stays in good condition. Use water and a soft cloth to remove any dirt build up around the inside of the tub or on the lid, paying particular attention to the waterline where there may be a build-up of grease. This will help to prevent damage to the material of the tub, maximising its lifespan.

You should also clean the hot tub’s jets in the same way — with water and a soft cloth to remove debris or dirt build-up. Don’t forget to clean the hot tub cover and any other accessories you may have, like pillows or drinks holders.

4. Other regular maintenance

Remember to keep your hot tub covered when it’s not in use. You should also shower before you use the hot tub, to keep the water as clean as possible.
