Cost to own: every tub
What every tub costs to buy and to use, on one axis, with the delivered price separated from the sticker.
Delivered price runs $325.50 to $16,299 and cost per session $2.09 to $104.48 across the 26 tubs.
How these are worked out
Delivered price is the record price plus a heater where one is sold separately, so a cabin that arrives without its heater is not compared against one that arrives with it. Cost per session divides the delivered price across the session assumptions stated below. Both derive from the record; neither is typed by hand.
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 |
