What Kotisauna Inc. does

Kotisauna Inc. (operating as Koti Sauna; legal entity Koti LLC) runs a single-location outdoor Finnish sauna and cold-plunge facility built into a residential backyard at 4128 SE Jefferson Street in Milwaukie, Oregon. The property comprises an accessory structure housing an indoor lounge, bathroom, two showers, and changing space, plus an outdoor Finnish cedar sauna heated to 185-195°F with three tiers of cedar benches and birch-scented steam, two outdoor cold plunges cooled to 40-50°F, two outdoor hot/cold showers, two firepit lounges, and a lawn area. Founders Kristina (Finnish-born, raised in Nissilä, Finland) and her husband Nick obtained a City of Milwaukie home business permit in late 2023 and multiple building permits, then completed approximately 18 months of construction before opening on June 4, 2025.

The core product is a two-hour community sauna session that bundles heat therapy, cold therapy, outdoor rinsing, and firepit relaxation with complimentary tea; customers self-pace the rounds. Secondary offerings include private facility rentals for groups of up to 15 guests (priced at $400 off-peak / $500 peak base plus per-guest and per-hour add-ons), wellness events pairing sauna with yoga or sound baths at $70-85 per person, recurring sauna memberships (unlimited and once-a-week tiers), bulk session packages, and gift certificates denominated from $40 to $300. The business is bootstrapped, founder-owned, and operated as an Oregon LLC with no external investors and 1-10 employees.

Koti Sauna sells exclusively direct-to-consumer through its own website (Acuity Scheduling) and phone/email inquiries, with marketing concentrated on organic social, an email newsletter, hosted community events, and partnerships with independent local wellness instructors. The addressable customer base is the Portland/Milwaukie metro area, with persona segments including wellness-focused individuals, private event hosts, wellness instructors renting the space, and families/couples. No mobile app, no AI-driven features, and no third-party distribution channels are in use.

Broad incumbents

• Sunlighten: Established infrared sauna brand that sells individual units and partners with studios that offer sauna sessions. Comparable through the same sauna-based wellness category, though primarily product-oriented rather than single-location operator.
• Remedy Place: Multi-location self-care/wellness club offering saunas, plunge pools, and a broader suite of recovery and wellness services. Comparable as a membership-based contrast-therapy offering, but at much larger scale and with a broader portfolio.
• SoJo Spa Club: Large multi-service spa facility in NJ featuring saunas, plunge pools, and thermal experiences as part of a broader wellness offering. Comparable as a thermal/contrast therapy operator, but at much larger scale and as part of a full-service spa.
• Finlandia Sauna: Long-standing sauna manufacturer and supplier of authentic Finnish sauna equipment. Comparable as a Finnish-credibility-marked player in the same sauna category, but operating in equipment manufacturing rather than direct consumer sauna services.

Direct peers

• Common Blocks: Portland-based neighborhood badehaus offering community sauna, cold plunge, and contrast-therapy sessions in a similar intimate, membership-friendly format. Directly comparable single-location Portland competitor with overlapping customer base.

• Block + Boiler Sauna Studio: Portland sauna studio focused on communal sauna sessions, cold plunge, and contrast therapy. Directly comparable as another small-format Portland sauna operator targeting the same wellness-focused customer.
• Sweat Tent: Outdoor sauna and plunge experience operator that hosts communal and event-style sessions. Closely comparable outdoor, event-driven contrast-therapy concept.

Regional players

• Kleos Sauna Co. Boutique NYC sauna studio offering sauna sessions, cold plunge, and curated wellness events. Comparable in format and pricing but operating in a separate metropolitan market from Koti's Portland base.
