Duravit D-Code vs Starck Toilets: Design and Specs

Two Design Languages from One Brand

Duravit, a German sanitaryware manufacturer, has collaborated with world-renowned designers to create distinct toilet collections. The D-Code series, designed by Norman Foster, reflects a precise, geometric approach with right angles, flat surfaces, and a visually lightweight appearance. The Starck series, designed by Philippe Starck, embraces a more sculptural, fluid form with rounded edges and a seamless transition between the tank and bowl.

When you are deciding between these two lines, think about the overall design of your bathroom. D-Code suits contemporary spaces with straight lines, such as those using rectangular tiles and linear fixtures. Starck pairs well with softer interiors, featuring curves in the bathtub, mirror, or vanity. Both collections are made from vitreous china and offer comparable flush performance, so the primary differentiator is visual.

• D-Code: angular, flat surfaces, defined edges, architectural feel.
• Starck: rounded, soft curves, organic flow, sculptural presence.

Shape and Silhouette

The shape of the toilet bowl is the most obvious difference. D-Code uses a rectilinear bowl that is wider at the back and narrows slightly toward the front, with a matching square seat. The tank is compact and sits flush against the bowl, creating a single block-like profile. Starck, in contrast, features a rounder bowl that feels more generous, and the seat is curved to follow the bowl's contour.

Consider how the toilet will sit in your bathroom. If you have a compact space, the angular D-Code may create a more streamlined appearance, while the rounded Starck can soften the room but may require a little more visual room due to its curves. Both are available in elongated and round versions, but you should verify the exact dimensions from the manufacturer before purchase.

Rim Design and Cleaning

Toilet rim design has a big impact on hygiene and maintenance. Both D-Code and Starck collections may include models with a fully rimless bowl, a feature that removes the inner rim and creates a smooth, flush surface. Rimless toilets reduce the areas where bacteria can hide and make wiping down the bowl much easier. You can learn more about the benefits in our rimless toilets explained article.

If you prioritize easy cleaning, look for the rimless version of either line. Not every model in these collections is rimless, so check the product specifications before ordering. Older or entry-level models may still have a traditional rim with jet holes. If you are remodeling, consider the long-term ease of cleaning; a rimless design is a worthwhile feature even if it is not the primary aesthetic factor.

Wall Hung Options

Both D-Code and Starck are available as wall hung toilets, which mount to a concealed carrier frame inside the wall. Wall hung models free up floor space, making the bathroom easier to clean and creating a floating appearance that complements modern design. They require a sturdy wall structure and a concealed cistern, so installation must be planned ahead of time.

Before choosing a wall hung model, review the wall hung toilet requirements to understand the framing and carrier needs. You can also browse our best wall hung toilets guide for popular options. If you are comparing D-Code and Starck specifically, both offer wall hung versions that use the same Duravit carrier systems, so the decision again comes down to the visual style you prefer.

• Wall hung toilets create a floating look and simplify floor cleaning.
• Both collections have wall hung versions with concealed tanks.
• Installation requires an in-wall carrier and sufficient wall depth.

Specifications to Compare

When you narrow down your choice to a specific model in either line, focus on the same core specs you would check on any toilet. Flush volume is a key specification: the EPA WaterSense label indicates that a toilet uses 1.28 gallons per flush or less while meeting performance criteria. Many Duravit models, including those in the D-Code and Starck lines, are available with WaterSense certified flush systems. Read more about WaterSense certification to understand what the label means.

Another important spec is the rough-in distance, the horizontal measurement from the finished wall to the center of the floor drain. Most homes in the U.S. have a 12-inch rough-in, but older or custom homes may differ. Our how to measure rough-in guide explains the process. Finally, look at the seat height and bowl shape to ensure comfort for all users. The ADA toilet requirements can give you a sense of accessible heights, but you do not need to follow ADA unless you are designing a public or commercial space.

How to Choose Between D-Code and Starck

The decision between these two collections is mostly about design character. D-Code will appeal to anyone who appreciates precision, symmetry, and a modern architectural edge. Starck will attract those who want a softer, more humanistic shape that feels less like a machine and more like a piece of furniture.

Consider your bathroom's existing fixtures, tiles, and lighting. If you are starting from scratch, look at interior design magazines or online inspiration to see which style resonates with you. If you are replacing an existing toilet, make sure the new model matches the rough-in and is compatible with your bathroom's layout. Use the table below to match your priorities to the recommended choice.
