About Us

Design, manufacture and installation of commercial and education washroom systems

Born from a manufacturing heritage of 50 years

1968 was the first year of trading for BH Dunham & Sons – suppliers of decorative laminate products. Working from his farmhouse garage in Norfolk, BH Dunham fabricated panels by hand and delivered to clients around the county in his Morris Traveller.

Over the decades, Dunhams has specialised in the market of bespoke washroom systems and with many longstanding customers, such as The Caravan Club UK, has been a trusted brand for quality of product and service.

2016 saw Dunhams take on a third dimension with the establishment of Cube Install Ltd offering design, supply and installation of Dunhams washroom systems all in one package for new build Education and Commercial projects. Cube Install is committed to setting the industry standards for professional washroom installations and safe working practices that others aspire to reach.

Our Vision

To become the undisputed, first choice sub-contractor for the design, supply and installation of washroom systems for new build Education and Commercial projects, including toilet cubicles, IPS duct panels, vanity units and wash troughs.
