Schlüter-KERDI-LINE-VARIO is a flexible, multi-piece, linear drainage system for creating floor level showers with ceramic tiles or natural stone.

Two design drainage profiles are available for KERDI-LINE-VARIO. These can be individually cut to size, are height adjustable and are available with two matching end caps.

The two-piece horizontal KERDI-LINE-VARIO drain unit comprises a drain body and a drain adapter. The drain body consists of an ultra slim, wave-shaped drain that is rotatable by 360° and a built-in odour trap. The wave-shaped design achieves a high flow rate within the floor drain, which results in a self-cleaning effect.

Schlüter-KERDI-LINE-VARIO-WAVE is a W-shaped drainage profile, which can be individually cut to size. It is also available in brushed stainless steel V4A or powder coated aluminium with a textured TRENDLINE finish and can be ordered in lengths of 120 cm and 180 cm.

The aluminium version is available in two profile widths, 34 mm and 42 mm. In the narrower version, the drain opening in the centre is only 14 mm wide and 140 mm long. The drain opening of the 42 mm wide version is 20 mm wide and 140 mm long, which offers sufficient space for inserting an optionally available hair trap.

The stainless steel version with a profile width of 42 mm features a drain opening that is 25 mm wide and 140 mm long. It also has sufficient space for inserting an optionally available hair trap.

All profile versions of KERDI-LINE-VARIO WAVE feature a visible drain opening which can be concealed from view with a removable panel.

1. Follow the installation instructions for the KERDI-LINE-VARIO drain body.

2. Apply covering materials such as tiles or natural stone. (Covering thickness must match the selected drainage profile).

3. Cut the drainage profile to size with a suitable handsaw to match the structural requirements on site, using the supplied cutting gauge (do not use an angle cutter) and de-burr the cut.

4. The set includes two end caps to create a simple and elegant finish.

5. Adjust the height of the drainage profile by filling with cementitious tile adhesive in such a way that it is flush with or just slightly below the covering surface.

The KERDI-LINE-VARIO-WAVE drainage profile is made in anodised aluminium with a textured powder coating or in brushed stainless steel V4A (material no. 1.4404 = AISI 316L).

Schlüter-KERDI-LINE-VARIO-COVE is made in anodised aluminium with an added high-quality textured powder coating. Also available in brushed stainless steel V4A (material no. 1.4404 = AISI 316L).

The wave-shaped drain and drain adapter are made from impact-resistant polypropylene (PP).

The KERDI waterproofing collar that is fixed to the drain adapter for joining to the bonded waterproofing assembly (see product data sheet 8.1) is made in a polyethylene membrane.

The clamping ring on the wave-shaped drain is made from coloured polyvinyl chloride (PVC).

The protective lid is made in transparent acrylonitrile butadiene styrene (ABS).

Material properties and areas of application

KERDI-LINE-VARIO drainage systems are classified as K3 based on DIN EN 1253 (Gullies for buildings). This class applies to areas without vehicle traffic. With the exception of the aluminium version of the WAVE profile, all drainage profiles can withstand wheelchair use.

Schlüter-KERDI-LINE-VARIO drainage profiles are available in a wide variety of materials and finishes. In applications exposed to chemical or mechanical stresses, the suitability of the profile must be verified on a case-by-case basis. The information below can only serve as a general guideline.

The COVE and WAVE drainage profiles in the brushed stainless steel V4A version (material no. 1.4404 = AISI 316L) are particularly suited for applications that, in addition to heavy mechanical stresses, require resistance to chemicals such as acidic or alkaline media and detergents. Areas of application include bathrooms in dwellings, nursing homes, hotels and schools and also public washroom and shower facilities. Even stainless steel is not resistant to all chemical stresses, and may be affected e.g. by hydrochloric or hydrofluoric acid and some chloride and brine concentrations. In certain cases, this also applies to seawater swimming pools. Suitability for specific anticipated stresses should therefore be clarified in advance.

The COVE and WAVE drainage profiles in aluminium (textured coated aluminium) feature surfaces with a natural appearance. The aluminium is pre-treated (anodised) and then powder-coated. The coating is colour-stable and UV and weather-resistant. Areas of application include bathrooms in dwellings, nursing homes and hotels. Visible edges should be protected against abrasion and scratching.
