There are 7 drain cover patterns available. The flow rate is the same for all of them. They are interchangeable and can be swapped even after installation. Each drain sent out is equipped with a lifting hook which makes cleaning easy.

Thickness

Thickness of the board on the edges. It has 2% gradient on the entire upper surface and is shallower near the drain. The benefit of thicker tray is steeper slope, although even the shallowest trays have sufficient slope for water to flow towards the drain, no matter where it drops.

Waterproofing kit

Waterproofing kit is used to seal shower tray as well as connections between walls and floor. It is recommended for concrete and mandatory for timber flooring. Each kit contains 4kg tanking liquid, 1l primer, 10m sealing tape, 2 corners, 2 pipe collars. One kit covers 3 m² with 2 coats. Waterproofing kit

Tanking kit

The tanking kit is a ready-mixed, under-tile tanking system to protect water sensitive substrates from exposure to water. Suitable for wet areas such as bathrooms, showers in residential buildings, hotels, old people's homes and hospitals. Should not be used in places exposed to pressurised water, for an instance swimming pools. Ready to use, no mixing required and easy to apply with a roller. 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 kit contains:
  • 4kg Tanking Liquid
  • 1l Primer
  • 10 Metres flexible Sealing Tape
  • 2 Flexible Pipe Collars
  • 2 Corners
Features:
  • Consumption to 1,2kg/m²
  • Solvent free
  • Drying time: 2h
Tanking liquid and primer
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.

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.

Integrated drain

Shower trays incorporate linear drain built-into the tray during the manufacturing process. Wiper Premium range linear shower drains are made from one piece of 304 grade stainless steel. Only the ends are welded. This means that the flange and drain body are made from the same piece of steel ensuring complete security from water penetration. Our flange is on all four sides of the drain. You will not find a better linear drain on the market.

Our OneWay wet room kits are available in two thicknesses: 30mm and 40mm. Depending on space, floor type, and desired gradient you can choose best option for you.

If you have timber floor - existing floor board thickness. Usually they are 30mm thick, in that case you should go for adequate thick wet room kit, to avoid floor height increase and step ups. If you want to achieve stepped up floor, 40 mm thickness might also be a good choice. In case of concrete floor, every thickness is suitable, if you're going to screed the floor you need to shutter the future shower area off and leave proper space for tray to be inserted in the future. If screed has already been done, you will need to use jackhammer or similar tool to groove exact tray thickness and shape when the shower is going to be created. In case of both floor types, every shower tray thickness is enough to bear human weight, as it needs to be underboarded beneath entire surface either with ply or solid concrete. The biggest difference between thicknesses is the slope's angle achieved after installation is completed and shower tray tiled.
