In short
A sauna needs stones repositioned annually and replaced every two to three years, elements inspected yearly and vents kept clear. A steam room needs descaling every three to six months depending on water hardness, a verified auto-drain after each session, and quarterly cartridge changes. A cold plunge needs cartridges every four to eight weeks and a quarterly condenser clean.
Wellness equipment does not fail randomly. It fails from scale, from moisture in the wrong place, and from filters nobody changed. All three are predictable, which means all three are avoidable.
Sauna
- Stones
- Reposition annually, replace every 2–3 years — they crack and choke airflow
- Elements
- Inspect annually; replace when heat-up time drifts past 20% of new
- Benches
- Clean and re-oil annually with a sauna-grade oil, not a floor finish
- Ventilation
- Check the inlet and outlet are clear — the most common cause of uneven heat
Steam
- Descaling
- Every 6 months on treated water; every 3 on untreated valley supply
- Auto-drain
- Verify it operates after each session — this is what prevents scale
- Water treatment
- Cartridges quarterly, salt monthly, dosing calibration twice a year
- Silicone and grout
- Inspect annually at the five junctions that fail

- Filter cartridge
- Every 4–8 weeks depending on use
- Water change
- Quarterly on residential, monthly on commercial
- Chiller condenser
- Clean quarterly — a blocked condenser costs capacity first, then the compressor
None of this is difficult. It is just easy to defer, which is why most of it ends up on a Care plan — the visit gets scheduled whether or not anyone remembers.
