It is most commonly used to be in vinyl, marble, stone, exotic wood or glass floorings. Entire drain including the grating should be covered with your finish material so only channels for water to flow are visible after installation. It comes with insulating flange and sealing membrane which allow to achieve 100% waterproof seal.

Wet room drains Invisible have included grate 80 mm wide and total width with flange is 140 mm. Cover is 1094 mm long and drain 1160 mm long in total.

Complete Underfloor Heating Kit
It is possible to include a complete Underfloor Heating Kit to your order. All you need to do is to choose the required size. Additional package, with heating mat, appropriate thermostat, sensor and instructions will be dispatched together with the other goods.

To calculate required mat size you need to get square coverage of the floor and exclude any permanent / fixed fixtures from them. It is also recommended to buy slightly smaller mat than calculated size - you can shape it but cannot cut the cables, therefore too large mat could not be installed.

SUNFLOOR Underfloor Heating
The SUNFLOOR Electric Heating Mat is a unique type of floor heating mat. The system has been designed to be used on an existing tiled floor or an existing finished floor, so that floor heating can still be installed there. The mat is approximately 4 mm thick and can be included in a layer of adhesive without any demolishing or grinding. The mat fits virtually underneath the surface. This decreases the heating time of the floor, that also makes this system suitable for rooms that are not permanently occupied including bathrooms, studies, playrooms, etc.

Heating mat
Underfloor heating mat set consists of all necessary parts for installation. One Thermostat is needed for every 23 m² of heating mat. It is included as optional, to allow ordering mat for custom areas, for example if you need 13 m² of mat total, you should buy 10 m² with one of the thermostats set as include and 3 m² with thermostat not included. In case you require less mat coverage than possible to buy from our product pictures, for example 14.5 m² you should always round low with your purchase and buy 14 m² as the mat is impossible to cut. It can be shaped but not shortened to size.

The kit includes a high performance joint reinforcing tape to protect against movement in floor joins and corners etc. The contents are all INSIDE the bucket and the contents are protected in the bucket with polystyrene infill's to stop transit damage.The instructions are printed on the rear of the tanking kit.

For anti-moisture insulation systems in wet rooms and rooms intended for human residence. The tanking liquid is a ready-to-use singlecomponent, solvent-free sealant composed of polymer dispersion, fillers and modifying additives. When applied to the surface, upon binding it creates a flexible and water-insulating layer.

Tanking liquid

Tanking liquid
The 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.

Primer

The 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.

Sealing mat

ISOL-ONE Sealing collar
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.

Adjustable legs

Adjustable legs
Adjustable feet are two small metal parts that can be connected to each channel end. They allow you to precisely set the unit height and level. Thanks to the red caps you can anchor the drain to the floor. They are part of unit, included in price and always added to each drain.

1 Product review for Linear drain Wiper 1100 mm Invisible
works with marble
It's not a clamp drain as I thought. The sealing membrane and your finish material has to be glued to the steel flange. It cannot go inside the drain under the grating cause it will stop water from flowing. But it works fine with thicker material like stone or marble.
