INFINITY I-Line – Technical

The new INFINITY I-Line from On The Level provides more space to stand than traditional wet rooms which have square or linear gratings.

The exclusive ‘invisible’ drain is a mere 8mm wide channel which edges the shower room wall. 

As you can see from the cross section to the left, the INFINITY I-Line is integrated into the wet room floor, embedded into the former then layered over with tile adhesive and tiles, eventually leaving nothing of our product left on show.

This page will provide you with all the tech-spec you need in order to measure up for an INFINITY I-Line system, however please feel free to contact us with any questions which you feel have not been answered.

1. The OTL trap gully can cater for a variety of flow rates; from 35 to 50 litres per minutes.
2. A removable housing plate sits here to allow for easy cleaning of the trap gully.
3. The INFINITY I-Line system is easy to install and includes full installation instructions.
