Warranty: every tub
The warranty term on every tub, and who stands behind it.
Warranty terms run 1 to 2 years across the 26 tubs. 19 carry no clean term, so the manufacturer's own wording is shown instead of a number.
How these are worked out
The term comes from the record. What a term actually covers is a brand promise rather than a product one, and it is rarely one number: a cabinet, a heater, controls and glass are usually covered for different lengths of time. Each brand page carries that full table with the date it was captured, so the brand here is a link to it rather than a summary of it.
Assumptions: electricity at $0.17 per kWh (US average), cost per session over 3 years at about 1 session per week (price divided by 156), sauna running cost at a 30-minute session. These are estimates for comparison, not quotes.

| Ownership | What it means |
|---|---|
| Upkeep | Water chemistry is the whole job: hold pH between 7.0 and 7.8, sanitise with chlorine granules or bromine, and drain and refill every 30 to 50 uses no matter how clear it looks. By frequency that is roughly every 4 to 12 weeks on one or two plunges a week, 1 to 4 weeks at three or four, and every 1 to 7 days for daily or multi-person use. |
| What you rebuy | Water test strips, Chlorine granules or bromine tablets, pH up / pH down, Stain and scale remover |
These apply to the class, not to this record alone, and they are sourced from the manufacturer guidance for it. Anything a source does not state is left out rather than estimated.
