The membership math

Two ways operators price it. Both beat a treadmill.

Bundled into the top tier

Four included recovery sessions a month at the top membership level. Operators tell us this is the retention play: the member who books a Thursday sauna after Tuesday's class has a mid-week reason to stay a member in February.

Sold as a drop-in

A paid recovery session alongside the class schedule — ancillary revenue from the same square metres, without adding a coach or a class slot. On ClassPass-connected studios it lists like any other inventory.

The dossier carries sector pricing benchmarks with their sources — so you can sanity-check the tiers against your own member base.

Boutique-gym FAQ

What studio founders ask before the dossier

  • How does this monetise alongside our class pricing?

    Two patterns we see most often: bundle session passes into membership tiers (e.g. 4 included recovery sessions per month at the top tier, paid add-on below that), or run sauna sessions as standalone paid drop-ins. Across the sector, the reported pattern is that the bundled approach drives retention; the drop-in approach drives ancillary revenue. The dossier carries pricing benchmarks from operator interviews.

  • Does it integrate with our booking software?

    Yes — Mindbody and Mariana Tek both expose the booking primitives we need. The HUUM JSON API ties into the session window so the cabin is pre-heated by the time the member arrives. For ClassPass-connected studios, recovery sessions sit alongside primary classes in the inventory; the bookings flow through your existing scheduler.

  • What's the capacity per session?

    4–5 bathers, 30–45 minute typical session. For a boutique gym running 1,200 active members and 6–8 high-intensity classes a day, the cabin operates as a recovery amenity for the post-class window. Capacity isn't the bottleneck; scheduling is — most operators run two slots per hour with a 10-minute hygiene turnaround.

  • Where does it install?

    Outside. The cabin is engineered for outdoor service — typically on the studio's rear courtyard, terrace, or any 2.52 × 3.96 m of relatively level ground (slope tolerance up to 15°) with a power feed within 6 m and crane access for the install lift. We do not retrofit indoor wet-room conversions; the EPDM roof + thermowood cladding + steel frame is designed for outdoor exposure, not for interior compliance pathways.

  • How does it survive intensive daily use?

    It's engineered for commercial-grade operation: 304-grade stainless hardware (316-grade for coastal sites), HUUM Drop 6 kW heater, Canadian hemlock cladding chosen for closed-grain stability through repeated heat-humidity cycling, and a hygiene turnaround between booked sessions. A boutique gym's session frequency is reviewed against the commissioning schedule before launch.
