A new significance for spatial design: Why drainage products are shaping design today

In recent years, drainage products have evolved from purely technical components into defining design elements in modern bathrooms. Shower channels and shower surfaces, in particular, combine functionality, expertise in materials and architectural appeal. At this year’s spring trade fairs, TECE is showcasing, through its new solutions, just how much the sense of space has become the benchmark for drainage products today – and why plumbing and heating professionals should consciously take this factor into consideration when planning for and advising customers.

Visual calmness as a new promise of comfort

Modern bathrooms are increasingly seen as cosy retreats. Minimalism, clarity and spacious areas dominate design. This is precisely where TECE’s development comes in: products such as the new TECEdrainway shower channel follow the principle of ‘less is more’ and focus on maximising the sense of space.

Thanks to its particularly slim design, it blends in seamlessly – exactly where the wall and floor tiles meet. Visually, it creates an elegant, clear line that makes a statement without being overly distracting.

TECEdrainway almost disappears in the wall-to-floor transition, creating a sense of space. TECEdrainway has been available since the end of 2025.

Thanks to a variety of finishes in stainless steel, black, brass or bronze, the shower channel can be used to create either a harmonious or contrasting effect – a small detail with a big impact on the overall look. The long-lasting PVD finish also ensures that the subtle aesthetic is preserved over time.

The integration of such unobtrusive drainage components allows the room to appear neat and spacious – a key factor for bathroom customers who value architectural calmness.

Seamless design for a maximum sense of space

Another trend that has a significant impact on the way a room feels is the seamless bathroom design. Seamless surfaces create a sense of visual spaciousness and provide the impression of enhanced room size: the fewer visual anchors the eye detects on floor or wall, the larger the room appears.

With TECEdrainline for liquid floors, TECE has developed a solution that meets this requirement precisely: thanks to the mineral cast coating on both the channel flange and cover, the floor covering can be extended right into the shower area without any visible interruption in the material. All that remains visible is the slim water inlet – just enough to show its functionality, but subtle enough to not compromise the sense of space.

The result: a uniform, flush-mounted appearance that looks ‘as if cast from a single mould’, creating an exclusive, calm ambience in the bathroom.

Shower surfaces as design elements

Shower surfaces have an even greater influence on the overall appearance of a room. With the integration of the Spanish mineral cast specialist hidrobox, TECE is expanding its drainage range to include three product lines made from two high-quality materials: a solid surface material coloured throughout and a compact composite of resins featuring a gelcoat surface. The shower surfaces are characterised by homogeneous surfaces, clean edges and a modern design language – factors that have an immediate influence on the overall ambience of the room. 

The models TECEup, TECEtones and TECEcore cater to different design styles:

  • TECEup offers a classic, versatile look, blends seamlessly into almost any interior design concept and can be cut to size on site where edges are not exposed – a major advantage in complex floor plans. 
  • TECEtones features a clear, striking geometric design and is available in 20 trend and basic colours – ideal for making a bold colour statement or creating tone-on-tone schemes.
  • TECEcore comes in brilliant white, with a solid surface material that is coloured throughout and that complements particularly high-quality, refined bathroom designs. Edges that are exposed remain uniform across the material – a benefit for working precisely and aesthetically.

The material determines the effect

Alongside shape and design, the quality of the material plays a crucial role in how space is perceived. Even here, mineral cast offers compelling advantages: a variety of surfaces, such as microtex, slate or smooth, create different lighting effects and thus have an influence on the atmosphere.

Furthermore, the material has a velvety, warm touch, which stems from its low thermal conductivity, as well as excellent sound-absorbing properties. It is precisely this combination of visual appeal, haptic qualities and acoustic features that makes mineral cast the ideal base for shower surfaces, which are not only technically convincing but also emotionally appealing.

Why spatial effects are crucial for plumbing and heating professionals

The examples show that drainage products are no longer merely hidden components. They have an active influence on the overall look and feel of a space – and thus on the purchasing decision.

This offers a number of advantages for installers, planners and retailers:

  • Higher quality in advising: Anyone who can explain the visual influence the layout of the lines, the materiality and the use of colour have on the design builds trust.
  • Greater design freedom: Drainage is seen as an integral component of bathroom design – not as an additional technical necessity.
  • New potential turnover: High-quality solutions such as seamless systems or coloured shower surfaces can be specifically marketed as added value.
     

Bottom line: Drainage has become a design feature

What used to be purely functional is now a key design feature. From ultra-slim drain profiles, to the flush-mounted aesthetics of seamless shower areas, as well as shower surfaces made from high-quality mineral cast – drainage products are playing an increasingly prominent role in the look and feel of modern bathrooms.

Plumbing and heating professionals who consciously utilise the effects of space create added value: for the customer, for the project – and for their own positioning as bathroom experts.
