Below is an instruction that describes a task. Write a response that appropriately completes the request.

### Instruction:

Create a detailed description for the following product: Advantix Vario, belonging to category: Wall Drain

### Response:
Due to its flat mounting depth of only 25 mm, the wall drainage system allows installation on the surface, in lightweight or exposed walls without damaging the masonry. The floor covering can be laid without interruptions and sloping sections. As the drain profile and the slotted grating can be cut to length to the millimetre, they can be used in lengths of between 300 and 1,200 mm. The simple slotted grating made of stainless steel runs centrally along a 20 mm wide drain joint. It ends with a discreet cover plate on both sides. The drain fitting is self-cleaning, which makes removal and maintenance of the odour trap unnecessary.
