HBOT — Long Session or 2-Person (90 min OR 2 people × 60 min)

KCTH's longer HBOT tier — flexible between two formats: a single 90-minute (1.5h) session for one person, or a 60-minute session for two people sharing the chamber. 220 PLN flat. Useful either for clients wanting a longer therapeutic dose or for couples / training partners who want to do HBOT together.

This tier is structured as an OR option: pay 220 PLN for either a 90-minute (1.5-hour) session for one person, or a standard 60-minute session for two people sharing the chamber. The two-person framing implies the chamber is at minimum a 2-person rated unit; the chamber model and ATA pressure are not published on KCTH's site. The 90-minute solo format gives a longer in-chamber dose for clients who feel a 60-minute session is too short for their protocol — common for longer recovery cycles, post-COVID protocols, or longevity-stack experimentation. The 2-person tandem format is popular for couples who want to do HBOT together, or for training partners coordinating recovery sessions; per-person cost works out to 110 PLN, the cheapest entry point on the cennik aside from the MultiSport/Medicover concession. Note that KCTH does not publish the chamber model, manufacturer, capacity beyond "2 people", or the ATA pressure tier. Parent batch research (Poland HBOT scan, April 2026) suggests soft-shell chambers in the 1.3 ATA range across Polish wellness studios. Confirm with the studio if a specific pressure or chamber type matters for your protocol. The tier is bookable at all four KCTH branches. Advance reservation is required — phone +48 12 312 07 37. Active chemotherapy and radiotherapy are flagged as contraindications on KCTH's site.
