Spa-Level Comfort

Spire’s upright, gently reclined seating is built so you can quickly settle in, breathe naturally, and look forward to each session.

The slatted backrest and upright, gently reclined seat give you full body immersion while keeping your spine supported and chest open so breathing stays natural and you can stay in longer.

With your legs and midsection stacked vertically, cold water drives blood flow more efficiently through your lower body and core, helping flush waste faster so you feel recovered and ready to perform sooner.

Tall cedar walls wrap around you so you feel held and hidden while still getting neck deep immersion, with space to relax your shoulders and breathe deeply, even up to 6'11" and 300 lbs.

Solid cedar and stainless steps let you step in from the feet up, sit, and slide under with control. Getting out feels just as secure, which makes a daily cold habit much easier to stick with.

Comfort of a Laydown, Health Benefits of a Barrel

Spire’s vertical hybrid seat lets you sit upright with feet down, breathe naturally, and get neck deep immersion in a compact footprint.

Handcrafted Italian Design

Designed in Italy and handcrafted in warm Canadian cedar with soft stainless edges, Spire brings architectural calm to any space.

Warm red cedar wraps the tub and steps, turning your plunge into a statement piece.

Fits beautifully on balconies, in side yards, garages, gyms, or spa rooms.

Smooth to the touch and corrosion resistant so it keeps its clean, modern look for a lifetime.

Hidden hoses, integrated steps, and a laser-etched logo give it a visually calm, minimal look.

Powerful Benefits of Cold Immersion

Recover Faster

Build Resilience

Improve Clarity

Boost Your Energy

In a League of Its Own

Spire Elite is the only cedar vertical hybrid cold plunge with a seated recline and 4 step filtration. Built like furniture in red cedar and 304 stainless, it sits below luxury barrels in price and far above plastic tubs in feel and finish.
