Editorial note on ordering

Hummel Medical, the practice of this site's editor, is listed first in the clinical section. This ordering is intentional and openly disclosed. All other facilities below are listed alphabetically by state, then alphabetically by facility name within state. Inclusion in this directory is not a clinical endorsement. This site does not accept payment for placement. Facility listings are based on publicly verifiable information at time of research, and operating details can change month to month. Call ahead to confirm intake, contraindication, and hydration protocols before your first session.

A note on what you are looking at

Very few US sauna facilities are operated under direct licensed-practitioner oversight. Most are wellness studios or bathhouses, which is not a criticism, it simply reflects how the category has grown. Each entry below is tagged as Medical-adjacent, Wellness studio, Bathhouse, Franchise, or Community co-op, so readers can make their own decision. Facilities that publicly marketed unsupported disease-cure claims, MLM panel resales bundled with sessions, or first-session solo access with no check-in were excluded where identifiable.

Red Flags for Your Own Due Diligence

Based on the evidence summarized on this site, the following language on a facility's website should prompt caution:

  • Explicit claims that sauna cures, reverses, or treats cancer, autoimmune disease, Lyme, mold illness, or heavy-metal toxicity.
  • "Far-infrared penetrates X inches into tissue" used as a mechanism-of-healing claim. This is a commonly repeated overstatement not supported by dosimetry literature.
  • No published session-length, temperature range, or contraindication guidance.
  • First-session solo access with no check-in procedure or waiver.
  • MLM-structured panel or blanket resale pitches bundled with session access.
  • Marketing that frames sauna primarily as toxin-clearance rather than circulatory, thermoregulatory, and recovery adaptation.

Readers prioritizing a conservative evidence base may wish to favor operators that describe benefits in circulatory, thermoregulatory, and recovery terms rather than toxin-clearance terms.

Gaps and limitations of this directory

Two verification items I cared about are not consistently disclosed in public-facing materials at any facility surveyed. First, specific intake screening scripts for cardiac conditions, medications, pregnancy, and alcohol use. Second, written contraindication guidance made freely available online. For a first session, request these documents from the facility directly. Equipment brand and model were also inconsistently published; inquiries should go to each studio. Because the sauna and recovery category has grown quickly, rosters change monthly. Google Maps pins were valid at time of research, but operating hours and ownership should be reconfirmed before travel.

Inclusion policy

Facilities are included based on (a) that a licensed clinician oversees sauna therapy where the Medical-adjacent tag is used, (b) that the facility does not publicly market claims unsupported by the evidence summarized on this site, and (c) that the facility discloses enough publicly verifiable information to allow readers to evaluate the basics of intake, session structure, and contraindication. Wellness studios, bathhouses, franchises, and community co-ops are included under their respective tags when they meet (b) and (c), even where licensed-clinician oversight is not part of the model. To suggest a facility or to request removal, email info@hummelmed.com. Inclusion is discretionary and not purchased.
