When it comes to keeping your spa
A well-maintained hot tub isn’t just a luxury — it’s a long-term investment in your health and relaxation. But even with the best intentions, many UK owners make avoidable mistakes when it comes to hot tub spa maintenance. These common errors can shorten your spa’s lifespan, increase energy costs, and lead to costly repairs.
Whether you’re a first-time owner or have years of experience, understanding how to care for your spa correctly can save you money, time, and stress. In this guide, we highlight the top maintenance mistakes and how to avoid them so your hot tub stays in pristine condition year-round.
Regular hot tub spa maintenance:
By avoiding routine mistakes, you can save money and enjoy a hassle-free spa experience every time you take a dip.
Improper pH and sanitiser levels can cause corrosion, scale build-up, and bacterial growth, leading to poor water quality and discomfort.
Tip: Test your water 2–3 times a week. Maintain pH between 7.2–7.6 and sanitiser (chlorine or bromine) at recommended levels to protect both your spa and your skin.
Dirty filters force pumps to work harder and reduce water clarity, while also increasing the risk of mechanical issues.
Tip: Rinse filters weekly and deep clean them monthly. Replace them every 12–18 months to keep your filtration system efficient.
Used water contains dissolved solids that chemicals can’t treat indefinitely, affecting water clarity and performance.
Tip: Drain and refill your hot tub every 3–4 months. Use a line flush cleaner before draining for a deep clean. Need help? Check out our professional cleaning service.
Many household cleaners contain ingredients that can harm spa components, stain surfaces, or foam up the water.
Tip: Always use spa-specific cleaners for the shell, cover, and jets to avoid damaging your equipment.
Airlocks, pump strain, or heater damage can occur if you turn on the tub without proper water circulation.
Tip: Always bleed air from the pump after refilling and check for steady flow before powering up the system.
Uncovered hot tubs lose heat, attract debris, and allow UV rays to degrade sanitiser — all of which affect your running costs and water quality.
Tip: Use a high-quality, insulated cover whenever the tub isn’t in use and inspect it regularly for damage or sagging.
Avoiding these hot tub spa maintenance mistakes not only protects your investment but enhances your day-to-day enjoyment. With regular care, the right products, and a bit of expert guidance, your spa can offer years of luxurious relaxation and health benefits.
