Maintenance
Commercial sauna maintenance: the daily, weekly and yearly schedule
By ThermaCare team · Published 2026-09-16 · Reviewed 2026-09-16 · UK guidance
Every day: wipe benches, walls and floor with the cleaner the manufacturer approves, run a drying cycle, check the emitters or heater and stones are clear and undamaged, check the door, controls and timer. Every week: a deeper clean, check fixings, vents and lighting, inspect for scorching or loose timber. Every month: check the heater guard and any sensor, review faults. Every year: the manufacturer service, the electrical checks and the fire risk assessment review. Record each item with a name and time.
Daily
Sweat and oils build up fast on timber. Wipe benches, backrests and floor after the last session with an approved cleaner, never a bleach or solvent that attacks the wood or the emitters. Run the drying cycle so the cabin does not sit damp overnight. Check nothing has been left on or near the heater.
Weekly and monthly
A deeper clean, a look at fixings and vents, lighting, door closer and seals, any signs of scorching or warping, and the heater guard. Note anything odd as a fault so it gets fixed rather than remembered.
Yearly
The manufacturer service, in line with the warranty. PAT for plug-in units. The EICR when it falls due. The fire risk assessment review, which should reference the sauna specifically.
Questions operators ask next
What should I clean a sauna with?
The cleaner the manufacturer approves, usually a mild, timber-safe product. Bleach and harsh solvents damage timber and infrared emitters.
How often should a commercial sauna be serviced?
Annually by the manufacturer-approved engineer, or as the warranty specifies.
