Top 10 Hot Tub Maintenance Mistakes to Avoid

Owning a hot tub is one of the best ways to relax, unwind, and enjoy your home. But like any investment, it needs proper care to stay in top condition. The good news is that hot tub maintenance doesn’t have to be complicated — you just need to avoid some common mistakes that can lead to cloudy water, broken parts, and costly repairs.

Here are the top 10 hot tub maintenance mistakes (and how to avoid them).

1. Ignoring Water Chemistry

Failing to test and balance your water regularly can lead to cloudy water, scale buildup, or even skin irritation.
✅ Tip: Test your water at least 2–3 times a week and adjust pH, alkalinity, and sanitiser levels as needed.

2. Using the Wrong Chemicals

Not all spa chemicals are created equal. Household cleaners, pool chemicals, or cheap alternatives can damage your hot tub’s shell and equipment.
✅ Tip: Always use hot tub–specific chemicals and follow the manufacturer’s dosing instructions.

3. Overusing Sanitisers

More sanitiser doesn’t mean cleaner water — it can actually damage components and irritate skin.
✅ Tip: Stick to recommended levels and shock your spa only as needed. Leave your lid open for half an hour after adding chemicals to minimise chlorine damage to your cover.

4. Neglecting the Filter

Your filter is the heart of clean water. Ignoring it leads to cloudy water and strain on the pump.
✅ Tip: Rinse your filter weekly, deep-clean monthly, and replace every 12–18 months.

5. Not Showering Before Use

Oils, lotions, makeup, and even laundry detergents can clog filters and affect water chemistry.
✅ Tip: Encourage bathers to rinse off before getting in.

6. Letting Water Sit Too Long

Keeping the same water for months without draining allows bacteria, scale, and foam to build up.
✅ Tip: Drain and refill your hot tub every 3–4 months (more often if heavily used).

7. Ignoring the Cover

A dirty or damaged cover lets in debris, raises energy costs, and reduces water quality.
✅ Tip: Clean your cover monthly and replace it if it’s waterlogged or cracked.

8. Running the Jets Without Enough Water

If your water level drops too low, running the jets can burn out the pump.
✅ Tip: Always check the water level before starting the jets.

9. Skipping Regular Inspections

Little issues like leaks, loose fittings, or worn parts can quickly turn into expensive repairs.
✅ Tip: Give your spa a quick inspection each week and schedule annual professional servicing.

10. Forgetting About Winter Care

In cold climates, failing to winterise properly can cause pipes to freeze and crack.
✅ Tip: If you’re not using your spa in winter, follow the manufacturer’s winterisation guide or have a professional do it.

Final Thoughts

Most hot tub problems come from simple oversights. By avoiding these common mistakes — and sticking to a regular maintenance routine — you’ll keep your spa water sparkling, your equipment running smoothly, and your investment protected for years to come.

Pro Tip: Keep a small maintenance log. Tracking water tests, filter cleaning, and refills will save you guesswork and help extend the life of your spa.
