Mariana

Mariana is uniquely deep crafted for full-body, vertical immersion. Inspired by the ocean trench that shares its name, this tall, circular tub invites you to stand, float, or sit fully enveloped in water. Its compact footprint conceals a powerful experience, offering a profound sense of release through height and depth.

Whether used for an invigorating cold plunge or a long, grounding hot soak, Mariana engages the body and calms the mind. It’s a space for reset and quiet intensity, perfect for solitary rituals or shared stillness. With its sculptural presence and handcrafted form, Mariana brings elemental immersion to gardens, retreats, and modern wellness spaces. A deeper ritual, shaped in water and wood.

Experience

We believe in designing experiences that reconnect us to the elemental and few are as powerful as full immersion. The Nordsprings Mariana is more than a soaking vessel, it’s a vertical passage into stillness. Inspired by the ocean trench that gives it its name, Mariana invites you to stand, float, or sink into depth awakening both body and breath.

Like descending into quiet waters, this tub is built with focused intention and enduring craft. We carefully select thermo-treated hemlock for its strength and natural beauty, each board shaped by hand dozens of times. Held together by custom stainless steel bands, Mariana stands tall without glue-relying on tension, time, and technique. It's a powerful reminder that depth doesn’t require excess only presence.
