Our market leading flooring systems lead the way in wet room design for both residential and commercial sectors.

On The Level's unique wet room flooring trays or 'formers' bring ultimate water control to wet room and shower room design. Manufactured from birch plywood, one of the most dimensionally stable plywoods, and with laminations bonded together using a phenolic resin, OTL formers bring inherent toughness and dependability to wet room construction, crucial for architects and residential installers.

Our passion for wet rooms goes back to the 1980's when Phil Clark, company founder and inventor of the patented OTL shower room former first started to see the need for a radically more effective kind of flooring. 30 years spent installing showering areas for local authorities gave him the insight and experience to develop the revolutionary OTL floor tray, the 'former' – a concealed shower tray constructed from the highest quality birch plywood and engineered to the most exacting standards.


Precision in manufacture underpins the perfect gradient needed for the quick flow of waste water and every one of OTL's shower formers has it. Advanced technology at the company's Leighton Buzzard premises has been fulfilling high demand for formers since 2004. With over 50 different sizes for all types of floors always held in stock and ready for next day delivery, OTL leads the UK market. Our confidence in the product is such that we offer a lifetime guarantee on all our manufactured formers.

We understand the importance of using and supporting sustainable sources of birch. The birch used to produce all of our formers is sourced from Finland, Estonia and Russia and is backed by PEFC comprehensive certification, creating an environmentally sound product manufactured to the highest standards in the UK.
