Idea and principle


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, requiring the correct fall from four sides. The square drain therefore complicates laying the floor and subsequent tiling. The solution to this problem was the basic idea behind Unidrain, and Unidrain found the perfect answer with its narrow, linear floor drain: Unidrain's floor drain is placed right up against one wall, which means that there only needs to be a fall from one side. And Unidrain’s patented flanges in the wall and floor provide a waterproof transition between the floor drain, the floor and the wall. With Unidrain, one product therefore provided a technical, simple and smart solution to the two typical sources of damage from floor drains: 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.
