DIN 18534 Part 1.8.3.2 specifically addresses the sealing of areas under / behind bath or shower trays.

Areas under / behind bath or shower trays must be protected against water. Sealing of these areas is to be carried out as follows:

  • connect the trough rim to the seal, for example, with trough edge sealing strips or frames
    or
  • carry out the waterproofing underneath and behind the trough if necessary with underfloor drainage.

Sealing joints on the tub rim are not a seal within the meaning of this standard.
