The Ultimate Guide to Hot Tub Maintenance

The Ultimate Guide to Hot Tub Maintenance

Owning a hot tub is one of life’s greatest luxuries – but to keep your spa running smoothly, clean, and safe to use, regular hot tub maintenance is essential. With the right care routine, your hot tub will not only last longer but also provide the best possible health and relaxation benefits.

In this ultimate guide, we’ll cover everything you need to know about hot tub maintenance, including water care, cleaning tips, and how to keep your spa in top condition all year round.

Why Hot Tub Maintenance Matters

A well-maintained hot tub means:

  • Crystal clear water that’s safe and hygienic

  • Lower running costs due to efficient heating and filtration

  • Longer lifespan for your spa components

  • Better hydrotherapy benefits without cloudy water or unpleasant odours

Neglecting maintenance can lead to bacteria growth, damaged equipment, and costly repairs – so it pays to stay on top of your spa care routine.

1. Hot Tub Water Care

Test Your Water Regularly

Check your hot tub water 2–3 times per week using test strips or a digital tester. This helps you monitor pH, alkalinity, and sanitiser levels.

  • pH: Keep between 7.2–7.6

  • Total Alkalinity: Aim for 80–120 ppm

  • Sanitiser: Use chlorine or bromine to keep water safe

Balance Your Chemicals

If your pH or alkalinity is too high or low, adjust using the appropriate chemicals. Balanced water prevents scale build-up, cloudy water, and irritation to skin and eyes.

Shock Your Hot Tub

Add a shock treatment (oxidiser) once a week to break down organic waste like oils, sweat, and lotions. This keeps your water fresh and crystal clear.

2. Cleaning Your Hot Tub

Clean the Filter

Your filter collects dirt, oils, and debris, so clean it every 1–2 weeks with fresh water and a specialist filter cleaner. Replace it every 12–18 months.

Wipe Down the Shell

Use a non-abrasive cleaner to wipe the inside shell of your hot tub. This prevents grime build-up and keeps it looking brand new.

Empty & Refill the Spa

Drain and refill your hot tub every 3–4 months, depending on usage. This refreshes the water and prevents chemical imbalances.

3. Seasonal Hot Tub Maintenance

  • Spring/Summer: Regular use means you’ll need to test and adjust chemicals more frequently.

  • Autumn/Winter: If you use your hot tub in colder months, ensure your cover is insulated and water levels stay consistent. For those not using it, winterise your spa to protect it from freezing temperatures.

4. Hot Tub Covers & Accessories

A high-quality, insulated hot tub cover reduces heat loss and keeps debris out. Clean the cover regularly with a mild cleaner to prevent mould and extend its lifespan.

Other accessories like steps, spa pillows, and headrests should also be cleaned and checked for wear.

5. Professional Hot Tub Servicing

While regular DIY maintenance is key, scheduling a professional hot tub service once a year ensures your pumps, heater, jets, and electrics are all working properly. This can catch small problems before they turn into costly repairs.
