First blends coming soon

The world's hot springs, in your bathtub.

Each blend starts from the published mineral analysis of a famous spring. We seal it in one giant bag that dissolves in hot water. Drop it in. That's the whole routine.

How it works

01

Pick a spring

Every blend is named for a region with famous thermal water and matched to its mineral profile: calcium, magnesium, sulfur, silica and more.

02

Drop the bag

One oversized bag per bath. No scooping, no measuring, no salt on the floor. The bag dissolves as the tub fills.

03

Soak

Twenty minutes in warm mineral water. Then read about the real spring and plan the trip on our sister site.

The first three

Calcium · Bicarbonate

Anatolian Travertine

Built on the chalk-white terraces of western Turkey, where calcium-rich water has run downhill for thousands of years.

Sulfur · Sulfate

Tuscan Sulfur

Modeled on the warm sulfur cascades of southern Tuscany. Yes, it smells a little like the real thing.

Silica · Sea salt

Icelandic Silica

Inspired by the milky-blue geothermal seawater of Iceland's Reykjanes peninsula.

Blend names describe the regions that inspired them. We are not affiliated with any spring, spa or resort. Our salts are for bathing pleasure only and make no health claims.
