Stig
Stig brings hot + cold immersion into a generous shared format designed for residential, hospitality, spa, and commercial wellness environments. Available in recessed or freestanding styles, it pairs sculptural stone, clean-water systems, integrated lighting, and precise 41–104°F temperature control with the quiet performance of external equipment.

Choose your technical configuration
Two configurations
Loki is available in two technical configurations. The integrated system keeps the equipment built into the bath for a streamlined, self-contained installation. The external system places the equipment in a separate cabinet or technical room for quieter operation and more flexible placement.

Recessed
The recessed configuration is designed to integrate into decks, terraces, spa floors, and custom wellness spaces for a seamless low-profile installation. Great for residential and commercial indoor and outdoor spaces.

residential & commercial
Personal wellness. Pro performance.
Stig at home
Home wellness retreat.
Plug-and-plunge installation means no equipment closet, no technician visits, no compromise on placement. The bath lives where the rest of the home lives — on the terrace, in the bathroom, beside the fireplace.

Stig for business
Commercial-grade.
Specified by gyms, recovery studios, and hotel spas. The integrated tech pack means no service room, no second cabinet to design around, and no unplanned downtime between clients.

A daily plunge rewires the nervous system & the day around it.
Dopamine release
Sustained dopamine elevation for hours after a cold immersion. Mood, motivation, and focus follow.
Metabolic rate
Brown adipose activation and a measurable lift in metabolic output during and after the plunge.
Norepinephrine
A controlled stress response that sharpens cognition and trains the body's recovery system.
For full effect
Eleven minutes of total cold exposure per week delivers measurable physiological adaptation.
Recovery time
Athletes report nearly halved soreness and recovery duration after intense training sessions.
Sleep quality
Consistent users report deeper, more restorative sleep — particularly when plunging in the evening.
Inflammatory markers
Lower circulating inflammation correlates with reduced joint pain and faster muscle repair.
Immune resilience
Regular cold exposure is associated with reduced sick days and improved immune cell activity.
