A floor drain is designed to divert water away from the shower area. The surrounding floor needs to have the correct fall towards the drain. If the fall is not sufficient – or even worse, if it slopes the wrong way – there is a risk of gaps and leakage, which can cause expensive damage to the building over the years.

Before Unidrain came onto the market, there was only the square floor drain in the middle of the shower area, which requires a correct fall from four sides. The square drain complicates laying the floor and subsequent tiling.

The answer to this challenge is Unidrain’s basic concept, and with our invention of the narrow, linear floor drain, we have found the perfect solution. Unidrain’s floor drain is placed up against one of the walls, which means that you only need a fall from one side and Unidrain’s patented flanges in the wall and floor provide a waterproof transition between the drain, the floor and the wall.

With Unidrain one product provides a technical, simple and smart solution to the two typical sources of damage from floor draining: The wrong slope and leakage.

Unidrain’s original idea and subsequent expansion of the product range have been thoroughly tested and meet all the standard requirements.
