Why regular maintenance matters
Skipping maintenance not only shortens the life of your spa, it can also put bathers at risk. Proper water care, filter cleaning and equipment checks ensure clean, safe water, reduce energy costs and keep your hot tub running smoothly.
Weekly tasks
- Test the water’s pH and sanitiser levels and adjust as needed.
- Top up chlorine or bromine to maintain a safe sanitiser level.
- Check the water level and top up if evaporation has lowered it.
- Wipe the waterline to prevent build‑up of oils and dirt.
Monthly tasks
- Remove and rinse the filter with a hose to clear debris.
- Use a filter cleaner spray to dissolve grease and oils.
- Inspect the jets and diverters for debris and proper operation.
- Clean and condition the cover to maintain its insulation.
Quarterly and annual deep cleans
- Drain and refill the spa every 3–4 months to remove dissolved solids. Use a line flush product before draining to clean internal pipework.
- After draining, wipe down the shell with a non‑abrasive cleaner and polish to protect the acrylic.
- Once a year, replace the filter, check the heater, pump and seals and arrange a professional service.
How much does maintenance cost?
- Test strips and chemicals typically cost around £20–£30 per month.
- Replacement filters cost around £25–£50 each; some tubs have multiple filters.
- A professional service can cost £150–£300 per year.
- Energy costs make up the largest part of ownership; efficient models cost about £1–£1.30 per day to run.
Tips to reduce maintenance costs
- Invest in a high‑quality insulated cover and keep it on when the tub is not in use to reduce heat loss and debris.
- Shower before entering the spa to minimise contamination and prolong filter life.
- Keep the water balanced; balanced water is easier to sanitise and reduces scale build‑up.
- Run the pumps and heater during off‑peak energy periods if your tariff allows to lower electricity costs.
Summary
With a consistent care routine your hot tub will stay clean, efficient and enjoyable for years. Skipping maintenance quickly leads to murky water, worn‑out equipment and expensive repairs.
