Concept & Principle

Unidrain’s floor drain is placed right up against one wall, which means that there only needs to be a fall from one side.

UNIDRAIN HAS TWO DESIGN series

ClassicLine
A Classic Solution

The line drain with the classic grating in brushed stainless steel is Unidrain’s original invention. A required frame holds the grating in place and provides a smooth transition.

The ClassicLine series consists of six different designs, which means there’s a solution for everyone.

Choose Between Six ClassicLine Grates

HighLine
An Exclusive Solution

The exclusive design range HighLine gives the bathroom an extraordinarily stylish look. The classic grating has been replaced with a brushed steel panel, and an air gap ensures that the water is led away. 

The HighLine range also includes the discreet Custom-solution, in which a cut tile similar to the surrounding tiled floor is affixed to create an almost invisible drain.

HighLine has even been developed into the HighLine Colour range. Here the frame and the panel have been developed so that they can match the other metal details in the bathroom.

HighLine Colour comes in hand-polished steel, as well as PVD-treated brass, copper and black.

Concept and Principles

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.

Patented Flanges

4 parts - 1 Drain

Before Unidrain came onto the market, there was only the square floor drain in the middle of the shower area, requiring a 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.

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 provides 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.

CHOOSE THE RIGHT DRAIN UNIT

There are many options for putting together a floor drain. Therefore, we have gathered a large selection of drain units that suit all types of projects, whether you want to place the drain against the wall or use it as a free-standing solution.

You can achieve exactly the look you want with a stylish drain grating from the ClassicLine range or a panel from the HighLine range. Floor drains can also be ordered with customised dimensions.
