The Spa at The Elms — Sound, Soak & Movement in Kansas City

The Spa at The Elms

Located inside a historic 1912 Tudor Revival hotel in Excelsior Springs, this massive 28,000-square-foot wellness sanctuary is famous for its subterranean Grotto. The Grotto offers a guided thermal circuit where guests move between dry saunas, steam rooms, cold plunges, and a Roman-style bath.

The story

Excelsior Springs built its entire reputation on subterranean mineral waters, and The Elms sits right at the historic epicenter of that soak culture. The current Tudor Revival structure dates to 1912—built after earlier wood-frame hotels on the site burned to the ground—and conceals a massive 28,000-square-foot wellness sanctuary beneath its grand brick and timber frame.

While standard hotel spas rely on cucumber water and soft lighting to do the heavy lifting, the underground sanctuary here leans hard on classic European hydrotherapy. The centerpiece is the Grotto, a subterranean bathhouse built specifically for contrast therapy—alternating intense heat with ice-cold shocks to reset your nervous system.

What it's like

Expect a sprawling stone-and-tile underground facility that feels completely insulated from the midwestern town above it. Access to the Grotto isn't a drop-in affair; you need a scheduled spa appointment, which grants you a dedicated 90-minute window in the thermal circuit prior to your treatment. Arrive early, change into your robe, and move systematically through the dry saunas, steam rooms, and cold plunges before soaking in the Roman-style bath.

The move: Take a scenic day trip to this historic resort, book a spa treatment, and arrive 90 minutes early to complete the Grotto's hot-and-cold thermal circuit together.
