Inspired by the calm ritual of traditional Japanese bathing, The Onsen Copper & Nickel Bath is designed to transform the act of bathing into a moment of restoration. Its sculptural form, gently curved rim and deep soaking interior create a sanctuary for quiet relaxation, whether placed in a contemporary bathroom, spa environment, or architectural retreat.
Formed from genuine copper with a beautifully polished nickel interior, the bath balances warmth and refinement. The exterior celebrates the natural character of copper, while the nickel lining provides a bright, elegant bathing surface that enhances light within the tub and creates a luxurious contrast between the two metals.
Unlike conventional bathtubs, the Onsen Bath is designed around the concept of immersive soaking. The generous depth allows the body to be comfortably submerged, encouraging stillness and relaxation. The softly rolled rim and elegant silhouette echo the proportions found in traditional soaking tubs while maintaining a contemporary architectural presence.
The reflective nickel interior gently catches light across the water’s surface, creating a calming visual quality that enhances the experience of bathing. This combination of form, depth and material transforms a simple bath into a restorative ritual.
Copper and nickel have long been used together in high-end bathing vessels and spa fixtures. Copper provides warmth, durability and natural antimicrobial qualities, while nickel offers a bright, refined surface that is smooth to the touch and beautifully reflective.
This pairing brings together the best of both metals:
• Warm architectural copper exterior
• Smooth polished nickel bathing surface
• Excellent heat retention
• Durable materials designed for longevity
The result is a bath that feels both traditional and contemporary, celebrating metal as a living material within the home.
At Proper Copper Design, every piece is carefully inspected and finished to achieve the desired tone and character of the copper exterior. The final polishing and preparation of the bath ensures the metal has a rich depth and clarity before installation.
Over time, the copper exterior will gradually develop a deeper patina, adding further character and individuality to the piece while the nickel interior maintains its bright and elegant bathing surface.
Sculptural Form
The elegant proportions of the Onsen Bath create a balanced presence within a room. The gently tapering body rises to a soft rolled rim while the integrated base grounds the bath visually, creating a timeless silhouette that works equally well in modern interiors or more classical spaces.
