Drainage Solutions for a 4m² Bathroom Renovation | Dallmer

Dallmer develops innovative sanitary technology that enhances drainage performance, reliability, and design in contemporary architecture. As a family-owned company manufacturing exclusively in Germany, the company combines uncompromising quality with pioneering solutions for modern bathroom spaces.

The DallFlex drainage system with the CeraFloor Pure shower channel from Dallmer was applied in a private bathroom renovation in Dortmund, Germany.

The project involved the conversion of an attic apartment into a single, connected living unit. As part of the renovation, an additional bathroom was created on the upper floor in a space not originally intended for sanitary use. With only 4 square metres available, the planning of the level-access shower required precise coordination of layout, slope, and drainage components to ensure both functionality and ease of use.

The DallFlex system enabled a space-efficient and installation-friendly solution for the compact bathroom. Its flexible connection options allowed the drain body to be positioned according to the spatial constraints, while the CeraFloor Pure shower channel supported free placement and on-site shortening. This made it possible to center the channel and draw the slope from both sides, reducing the required gradient within the limited floor build-up. The system also simplified waterproofing through its click-on sealing sleeve, supporting a clean interface between installation and tiling works in accordance with DIN 18534.

In daily use, the CeraFloor Pure shower channel contributes to straightforward maintenance. The removable insert allows quick access for cleaning without removing the entire channel, supporting hygiene and long-term usability in a small bathroom environment.
