Stainless steel, widely regarded for its strength and resistance to corrosion, owes its existence to the discovery of chromium—a key element that transforms ordinary steel into a durable, oxidation-resistant alloy. The name chromium comes from the Greek word chroma, meaning color, reflecting the striking hues of its various compounds, which have been used throughout history to create pigments, paints, and even gemstone coloration in rubies and emeralds.

Though steel has been used for thousands of years, it wasn’t until the early 20th century that metallurgists realized that adding chromium—at least 10.5% by weight—created a material that resisted rust and tarnish, making it ideal for applications requiring both durability and aesthetic appeal. This breakthrough led to the birth of stainless steel, a material that would revolutionize industries ranging from construction and aerospace to medical tools and luxury spa design.

Today, stainless steel is an essential part of daily life—found in everything from architectural masterpieces and high-performance engines to the stunning, modern hot tubs that DaVinci Spas crafts with precision and care.

Scientific Details
At its core, stainless steel is an iron-based alloy that derives its remarkable properties from chromium, typically making up 18% of the composition in high-grade stainless steel. This element forms a thin, invisible oxide layer on the surface, preventing rust and corrosion—even in extreme conditions.

There are two primary sources of chromite (the mineral from which chromium is extracted):

• Porphyry Chromite Deposits: Found in mountainous regions, particularly in western North and South America, these deposits form when molten rock cools and solidifies, allowing chromium minerals to accumulate.
• Sedimentary Rock-Hosted Chromite Deposits: These deposits, accounting for about a quarter of the world’s chromium supply, form when mineral-rich water circulates through ancient rock formations, slowly depositing chromium over time.

Stainless steel is widely recycled, with more than 60% of U.S. chromium consumption coming from recycled materials. This makes it a sustainable choice—one that reduces reliance on newly mined resources while maintaining uncompromising quality.

Hygienic Resilience
One of stainless steel’s most defining characteristics is its natural resistance to bacteria, staining, and corrosion. Unlike porous materials that trap moisture and harbor microbial growth, stainless steel remains smooth, non-reactive, and easy to clean—qualities that make it indispensable in hospitals, commercial kitchens, and luxury spas.

The protective chromium oxide layer prevents microbial adhesion, meaning that less cleaning effort is required to maintain a pristine, sanitary surface. This self-renewing layer continuously regenerates when exposed to oxygen, allowing the material to retain its integrity for decades with minimal upkeep.

For spa environments, where cleanliness is paramount, stainless steel’s hygienic advantages shine. It resists the buildup of algae, biofilm, and mineral deposits, ensuring that every soak remains as clean and pure as the first.

Maintenance
Caring for a stainless steel spa is remarkably simple, requiring only basic routine maintenance to keep its brilliance intact. Because of its non-porous surface and resistance to chemical wear, stainless steel does not require abrasive scrubbing or harsh chemical treatments to remain in top condition.

For regular upkeep, rinse with fresh water after use to prevent mineral buildup, use a soft cloth and mild cleanser for occasional cleaning, and avoid harsh abrasives, which can dull the surface’s natural sheen.

Unlike other materials that degrade over time, stainless steel maintains its structural integrity, making it a long-term investment that withstands years of exposure to water, heat, and the elements.

Design Notes
Stainless steel is more than just a material of function—it’s a statement of style. Its sleek, mirror-like finish reflects light beautifully, creating a sense of movement and elegance in any setting. Whether polished to a high sheen or brushed for a softer, more contemporary look, stainless steel adapts seamlessly to a wide range of architectural styles.

For modern spa design, stainless steel is a versatile and sophisticated choice, particularly in settings that demand both form and function:

• Infinity-Edge Spas: The seamless surface of stainless steel enhances the illusion of a vanishing waterline, creating a sleek, sculptural aesthetic.
• Commercial Wellness Spaces: Hotels, luxury resorts, and high-end fitness centers opt for stainless steel for its durability and low-maintenance qualities.
• Challenging Installations: Thanks to its lightweight yet incredibly strong composition, stainless steel is ideal for spas installed on rooftops, balconies, and elevated decks.

From intimate residential retreats to bold, statement-making commercial installations, stainless steel elevates spa design with unmatched durability, beauty, and ease of care.
