Entry No. 40 — the Nashville file — filed under: soak
Salt and Soles
Since 2017, a small Edgehill storefront has run its own custom-built salt cave, where you recline in a zero-gravity chair breathing sterilized microscopic salt crystals for 40 minutes while an Amethyst BioMat — a mat embedded with heated amethyst crystals — warms your back; reflexology and sound baths are stacked onto the same visit.
The story
Tucked into an unassuming Edgehill storefront on Wedgewood Avenue, Salt and Soles skips the slick, linen-draped polish of a hotel day spa for something much stranger and more focused. Opened in 2017, the sanctuary centers around a custom-built salt cave—a sealed enclosure designed to flood your lungs and skin with airborne micro-particles of pharmaceutical-grade salt while you sit suspended off the hardwood floor.
What keeps it genuinely weird isn't just the cave itself, but how heavily they layer wellness subcultures onto a single visit. Tipped back in a zero-gravity chair inside the chamber, your back rests on an Amethyst BioMat—a specialized heating pad packed with crushed amethyst crystals radiating far-infrared heat directly into your spine. Stack a foot reflexology treatment or a live sound bath on top of the 40-minute salt breathe, and you've quietly entered one of the densest decompression chambers in Davidson County.
What it's like
Step inside, pull off your shoes, and prepare to sink into a dimly lit, dry room lined with glowing salt blocks. Once the halogenerator kicks on, it grinds and disperse microscopic salt crystals into the air; you won't see a thick cloud, but you'll taste a delicate salt crust on your lips within twenty minutes while the heated amethyst mat warms your back. The session runs 40 minutes on the hour. Tip: Wear comfortable, loose-fitting clothes and clean socks, and call ahead to pair your salt session directly with a foot reflexology add-on so you don't break the spell between treatments.
The move: Book a joint salt-cave session on the hour, then each add a reflexology add-on afterward so you leave with two very different kinds of relaxed feet and lungs.
