Where this comes from
Source: the venue's Google Maps listing (category "Spa"), checked November 2, 2026, and the venue's own website. We list it as a bathhouse because of its own website describes a hot and cold circuit with a sauna and cold plunge. Ratings are Google's, shown as a count only; we do not copy reviews. Prices are not shown because they change; see the venue's site. Is something wrong, or has it closed? Email contact@saunasnear.com and we will fix it.
