Certification mark for shower trays


The certification mark applies to shower trays.

Basis of certification:

The test procedure developed by TÜV SÜD is based on standards such as DIN 18040-1 (Construction of accessible buildings – Design principles – Part 1: Publicly accessible buildings) and DIN 18040-2 (Part 2: Dwellings).

Key words of the certification mark:


  • Barrier-free

    The products certified by TÜV SÜD offer barrier-free accessibility. This means that the design of the products ensures accessibility for people of all ages and different abilities, with and without disabilities or other handicaps.

    The certified shower trays are not more than 2 centimetres below the surrounding floor. The junction between tray and floor is preferably designed as an inclined plane. The movement area should be at least 120 x 120 cm in dwellings and 150 x 150 centimetres in publicly accessible buildings.

  • DIN 18040-1
    Testing is based on the DIN 18040-1 standard (see Basis of certification). The standard defines the requirements for accessible buildings and structures. It applies to the barrier-free accessible design, execution and fit-out of publicly accessible buildings.
  • DIN 18040-2
    Testing is based on the DIN 18040-2 standard (see Basis of certification). This part of the standard applies to the barrier-free, accessible design, execution and fit-out of dwellings and buildings with flats.
  • Type tested
    The voluntary TÜV SÜD certification mark with the statement “Type tested” is issued for products and components, indicating that the product was tested and certified by the independent third-party organisation of TÜV SÜD Product Service for conformity with the essential technical safety requirements. The certification criteria vary depending on the products in question.
  • Production monitored
    Periodic surveillance of the manufacture of a product constitutes the basic premise for certification which includes the award of a certification mark. Certification always requires product testing and regular factory inspections.

    As a third-party expert organisation, TÜV SÜD verifies that the manufacturer is able to maintain consistent quality in line with the requirements throughout high-volume production and has established the necessary quality system, including incoming goods inspections, lists of materials and final product check.

    In addition, calibration of the necessary measuring and monitoring equipment must be ensured. Surveillance and/or monitoring covers the testing of safety-critical components and other materials used. If unauthorised changes are made to the product, the certificate will be withdrawn and the TÜV SÜD certification mark may no longer be used.
