Maintaining your Nordsprings tub: tips for longevity and performance

Handcrafted with intention, Nordsprings tubs invite presence and renewal. Their longevity mirrors the care you give them. Like a ritual, maintenance becomes part of the experience enhancing every soak, preserving each material, and supporting lasting performance. This guide shares practical, expert-backed care practices to help your wellness space remain pristine and functional over time.
Care begins with understanding the materials
Every Nordsprings tub is crafted from thermally modified wood, chosen for its strength, low maintenance, and graceful aging. This natural material resists rot, moisture, and pests while retaining a refined appearance. But wood remains a living material. It expands and contracts with temperature shifts and humidity. This responsiveness is part of its character, not a flaw. Recognizing how wood behaves allows you to support it: a light, consistent routine protects its finish and ensures the tub matures beautifully in your landscape, year after year.
Protect the surface
To protect your wooden tub’s surface, rinse it gently after each use to remove any buildup from minerals, oils, or plant debris. Using a soft cloth, dry the inner surfaces, especially edges and seams, to prevent lingering moisture. Avoid harsh chemicals, which may strip the wood of its natural oils or finish. Instead, opt for a mild, pH-neutral soap diluted in warm water. A clean microfiber cloth can go a long way in maintaining the soft, natural sheen of the tub without damaging its texture or structure.
Respect the grain
Wood responds to the elements. In warmer climates, it may expand slightly; in drier ones, it may contract. These shifts are subtle and natural. By keeping water levels stable and placing the thermal cover when the tub is not in use, you reduce stress on the structure and prolong the tub’s integrity. If you’re using the tub in varied climates, consider scheduling weekly checks to ensure the wood remains evenly hydrated and properly supported throughout seasonal changes.

Support the system behind the soak
Beyond the craftsmanship lies a carefully engineered system. The Nordsprings Mineral Enrichment System works quietly to purify your water, infuse minerals, and maintain a consistent bathing experience. It requires minimal effort, but thoughtful attention ensures it remains efficient. Supporting the system means more than upkeep, it’s a way of preserving water quality, maximizing the benefits of each bath, and honoring the intention behind the design.
Refresh the mineral core
The Mineral Enrichment Core is essential to the wellness experience your tub provides. Over time, mineral saturation and exposure to environmental conditions reduce its effectiveness. We recommend replacing the core every 6 to 8 months depending on use, water hardness, and climate variations. Doing so ensures that your water remains pure, mineral-rich, and gentle on skin. You can order replacements directly from our online showroom and follow the included guide for a smooth update that keeps your system flowing effortlessly.
Balance and drain with intention
Water balance is key. Whether you use a recirculating or fill-and-drain system, testing the pH and mineral concentration regularly ensures your bath remains both safe and soothing. For recirculating systems, a weekly check is ideal. For fill-and-drain models, draining every few days or after multiple sessions prevents stagnation. Once drained, allow the interior to dry completely before refilling. This practice helps protect the wood’s natural structure and supports consistent thermal performance throughout the year.
Integrate care into the experience
At Nordsprings, we believe maintenance should feel like part of the ritual, not a chore, but a gesture of intention. A few quiet moments spent wiping the rim, checking mineral levels, or rinsing the interior can ground your connection to the tub itself. These actions maintain not just the object, but the space it creates, one of calm, clarity, and balance. Over time, the wood may shift in hue, revealing new tones that tell the story of use and nature’s passage.
A living material
You may notice slight changes in the tone or grain of your tub over the years. These aren’t flaws, they’re expressions of the wood’s life, echoing each season and soak. This transformation is part of what makes the material honest and alive. With consistent care, the structure remains strong, the comfort intact, and the visual presence quietly elevated. The tub becomes more integrated with your home and landscape, holding memory as much as it holds water.
A legacy of care
By caring for your tub, you’re investing in its presence, not just today, but for years to come. Each gesture of attention reinforces its resilience.
