The Kaldewei Classic Duo Steel Bath is a premium choice double ended model created for shared use. Utilising a central waste and overflow, this bath provides two identical backrests and a balanced oval interior, allowing two bathers to relax together. The design features steeper internal walls, which permit a deeper soak with a generous internal height of 430mm.

The Process of Steel Enamel

Every Kaldewei bath is a product of a specialized manufacturing process that has made the manufacturer a global authority. Steel sheets are pressed into the signature ergonomic oval form under immense pressure before a unique enamel, composed of natural minerals such as quartz and sand, is applied.

This raw composition is then subjected to the intense heat of a furnace exceeding 800°C. In this fiery environment, the steel and glass enamel undergo a molecular fusion, emerging as a single and inseparable material. The resulting finish possesses the hardness and the resilience of metal, shielding the bath from scratches and ensuring the surface remains immune to UV light. This specialized method guarantees that the bath preserves its brilliant white luster and smooth texture, looking exactly as it did the day it was first installed.

The Kaldewei Classic Duo Oval is a premium selection inset steel bath, designed to be dropped in to a pre-built supporting structure rather than standing alone or using traditional panels. This double ended model is best suited for shared relaxation, providing two identical backrests and a central waste for a harmonious bathing experience. With a generous internal depth of 420mm, it offers a deep and immersive soak. The rim of the bath is perfectly oval.

Designing Your Bespoke Installation

The Classic Duo Oval is an inset model designed to be integrated into a custom structure. Traditional clip-on bath panels cannot be used with this shape. Instead, this bath acts as a centrepiece that requires a bespoke surround, typically constructed on-site by a builder or specialist joiner.

This process gives you the creative freedom to design a unique feature in your bathroom. Common installation methods include:

• Tiled Platforms: Building a moisture-resistant frame and tiling the top and sides to match your bathroom decor.
• Luxury Stone Decks: Using marble, granite, or quartz slabs to create a solid, high-end furniture look.
• Natural Timber: Using treated wood for a spa finish.
• Sunken Layouts: Recessing the bath into a raised floor area for a dramatic, low-profile entry.

The Science of Steel Enamel

Kaldewei is a global authority in the creation of steel enamel, a material born from a specialized fusion of raw steel and tough glass. The process begins with steel sheets being pressed into the precise Classic Duo form. A unique enamel, a proprietary mix of natural minerals such as quartz and sand, is then applied.

In a high temperature furnace exceeding 800°C, the steel and glass undergo a molecular fusion to become a single, inseparable unit. This finish provides the resilience of metal and the smoothness of glass, creating a surface that resists scratches and is immune to UV light. Your bath will retain its smooth luster without yellowing or fading over time.

Made with Sustainablity in Mind

The bath body consists entirely of natural raw materials and is 100% recyclable at the end of its life cycle, standing in contrast to synthetic materials that often end up in landfill. Reflecting this, the Classic Duo is Cradle to Cradle certified. This certification is a globally recognised measure of safer, more sustainable products made for the circular economy, ensuring that materials are kept in a continuous cycle of use and reuse without generating waste. By choosing steel enamel, you are opting for a circular product that respects the environment.

Additionally, the material acts as an efficient thermal conductor, absorbing warmth from the water to keep your bath temperature stable for longer.

Configuration and Installation

To ensure a precise and stable installation, each bath comes complete with the official Kaldewei leg set. This ensures the structural integrity of the unit is supported correctly according to manufacturer standards.

The Classic Duo is available in a versatile range of dimensions to suit various bathroom layouts. This model is supplied without predrilled tap holes, offering a significantly tidier look and providing a clean, uninterrupted rim. It is the ideal choice for pairing with wall mounted taps or a floor standing filler, which frees up the bath deck and creates a streamlined and minimalist finish.
