Hot Tub Maintenance Tips for Long-Lasting Enjoyment

Your hot tub should feel like a place of calm and comfort. Looking after it should feel simple and worthwhile. With simple upkeep, you can enjoy clean water and consistent performance.

A hot tub offers a space to unwind, recover, and enjoy everyday luxury at home. But to keep it that way, it needs some attention. The good news is maintenance doesn’t have to be complicated or time-consuming. In fact, it can be straightforward and satisfying.

Below, you’ll find the most important maintenance habits to follow throughout the year. Each one is quick to apply and helps your spa stay safe, efficient, and ready whenever you need it.

1. Keep your water balanced

The water should always feel fresh, clean, and comfortable on your skin. That means checking and adjusting the pH, alkalinity, and sanitiser levels two to three times a week. If your water goes cloudy, smells off, or leaves residue, it’s a sign the chemistry’s off. Use spa test strips and follow up with the right products to rebalance it. This protects your skin, your equipment, and the clarity of your spa. Using test strips purchased from your retailer ensures you can accurately check the levels. For those more technology savvy individuals, or those suffering from colour blindness, digital test strip readers or digital water test kits provide the ultimate in convenience. 

2. Don’t forget your filter

The filter quietly does the heavy lifting trapping hair, oils, and debris to keep the water clean. Rinse it weekly and clean it properly with a filter cleaner every month. It’s also a good idea to replace it every 12 months. A well-maintained filter means your system runs more efficiently, and your water feels better for longer. Always have a spare clean filter to swap in and out when cleaning so your spa always have a filter in it. It allows the existing filter to dry. Using a filter cleaning product like NU Filter Cleaner prolongs the life of the filter and ensures bacteria is removed. Just like when you wash your dishes you use a washing up liquid, with a filter you should use a dedicated cleaning product.

3. Drain and refresh every few months

Even with good water care, everything builds up over time: minerals, oils, soaps, debris and more. To keep things running smoothly, completely drain and refill your spa every three to four months. Use this moment to wipe down the shell, inspect your jets, and check for any wear and tear around fittings and seals. Some hot tubs like Self Cleaning hot tubs by Hydropool allow the water clarity and cleanliness to last longer. Professional companies offer dedicated after sales engineers to do this for you- let them take care of this as they may spot small issues and ensure your spa is running as efficiently and smoothly as possible.

4. Look after your cover

The cover protects your spa from debris and helps retain heat. But it needs care too. Wipe it down regularly with a soft cloth and a gentle soap solution, then rinse it off well. Apply a UV protectant to prevent cracking in the sun and check the seal to hold in heat and lower energy bills. Dedicated products can help here – ask your spa professionals. Replace your cover every few years to keep your running costs low.

5. Run your jets even when you’re not using it

Circulation is essential. Running your jets keeps the water moving and helps prevent any build-up in the lines. Use the built-in circulation mode or timer if your spa includes one. If not, run the jets for 15–20 minutes a day to keep the water in good condition. Self cleaning hot tubs are brilliant too.

6. Use spa-safe cleaning products

Regular household cleaners damage your hot tub’s surface and disrupt water chemistry. Instead, use spa-safe cleaning products designed for acrylic shells and covers. These are gentle but effective and won’t leave behind any residues. Some brands even have their own range of concentrated high quality products. Investing in the right products ensures easy life long spa ownership.

7. Prepare for winter

If you’re using your hot tub year-round, make sure it’s well insulated and that your heater is functioning properly. If you plan to shut it down over winter, you’ll need to winterise it. Drain it completely, blow out the lines, add antifreeze, and cover it securely to prevent freeze damage. Some spas have energy efficient modes like economy or standby. Make sure your cover is snug around the outside shell.

8. Stay alert to signs of wear

Spotting small issues early helps you avoid more costly problems later. Listen for unusual sounds from the pump or heater, check for leaks under the cabinet, and look out for error codes on the control panel. A quick check once a week can save you time and money down the line.

9. Book in your annual service

Some maintenance is best done by a professional. Schedule an annual service to ensure efficient, safe performance and peace of mind. You can also ask questions or explore upgrades during your appointment.

Frequently Asked Questions

How long should I wait to use my hot tub after adding chemicals?

It’s best to wait at least 30 minutes after adding chemicals like pH balancers and sanitisers. Please wait 6 hours after high dosage shock treatments! Always test the water again before entering to ensure levels are within the safe range.

What is the ideal temperature for my hot tub?

Most people find 37–39°C (98–102°F) comfortable. However, it’s recommended to keep temperature below 40°C (104°F) to avoid overheating and ensure safety, especially for children or those with health concerns. Most hot tubs can range from cool to hot and you choose depending on the outside weather and your preferences!

Can I use my hot tub every day?

Yes, daily use is fine if your water is balanced and clean. Most people enjoy a session length of 15 to 30 minutes to relax.

How can I reduce energy costs?

Use a high-quality, well-insulated cover, lower the temperature slightly when not in use, and check that your tub has efficient heating and circulation systems. Running your jets and heating during off-peak energy hours can also help. Check your spas CEC manufacturer energy efficiency rating. The high quality spas have different energy efficiency settings too!

Can I drain my water into the garden or storm drain?

It depends on your local regulations. In most cases, you’ll need to let chlorine or bromine dissipate before draining to avoid harming plants or aquatic life. Always check guidance from your local authority.

How do I remove strong odours from my hot tub water?

A strong smell is usually a sign of water imbalance. Check your chemical levels and clean the filter. If the issue persists, it may be time to drain and refill the tub. Feel free to contact us if you are unsure.
