Linear shower drain advantages

Adjustable legsAdjustable feet are two small metal parts that can be connected to each channel end. They allow you to set the unit height when installing down the concrete floor. It can be easily removed if necessary for installation in timber floor.

They are part of unit, included in price and always added to each drain.

The ISOL-ONE sealing mat is made from a polyethylene film coated with a special non-woven fabric on both sides, so that it bonds with the glue layer. Its installation is recommended in all areas that require sealing. The mat is resistant to the cracking of the substrate, ensures the seal up of the entire surface, reduces installation time, allowing to lay the tiles immediately after gluing the mat.

Sealing membrane

The drain includes a new patented SMART TRAP® stainless steel siphon with a capacity of 38 l/min and the Easy Clean system.

Tanking liquid

Tanking liquidThe tanking liquid is a ready to use, single component, solvent-free sealant mass, consisting of polymer dispersion, fillers and additives. When applied to a substrate and cured, it forms a flexible waterproofing coating. The product is intended for use inside places intended for human residence, especially in humid areas (such as bathrooms, kitchens, laundries), to perform insulation against moisture under linings and coverings, such as ceramic tiles, glazed tiles, terracotta, wooden floors and panels, and synthetic carpets.


Tanking primerThe product is intended for priming absorbent and porous surfaces, inside and outside buildings. It is especially recommended for cement - limestone plaster, gas concrete, plaster-carton boards and cement plaster. The primer has a high penetration ability, is deeply absorbed into the substrate, thus strengthening it, while allowing for „breathing”. These benefits improve the structure of the substrates, which, due to the passage of time, have lost their appropriate parameters. The priming solution improves adhesion to the surface of other materials that will be used on the primed substrate. By reducing the absorbency of the substrate, the wear of the applied coating materials, emulsion paints, glues, mineral putties reduces as well. The solution, due to the content of the biocide and fungicide, protects the primed substrate against the formation of mold and bacteria in the product.

delivered on time. Installation went well and it looks nice. So why 4/5 stars? Well it's the price and I would prefer PVC waste trap than steel.
