Specifically designed for communal hand washing, a wash trough replaces rows of individual sinks with one long narrow basin which can accommodate multiple users. Premixed water is supplied at a fixed temperature from taps positioned at regular intervals. And one of the most popular features is that the troughs don’t fill – helping to reduce the risk of flooding.

Here at ONVO, we firmly believe that providing modern, safe and attractive washrooms, is a necessity, not a luxury. As such, we are committed to supplying only the highest quality products.

Our range of wash trough sinks offers something for all settings. Take for example the ultra slim Latherwash 2D curve, which only protrudes 400mm from the wall making it a great space saver. Or the Latherwash 2N which can be fitted at a height of just 500mm  – ideal for very young children. All our trough sinks come in a range of lengths, typically starting at 600mm and extending to 3000mm (bespoke lengths available on request), with a choice of colours, sensors taps and soap dispensers to choose from – so we’re confident we can provide the ideal trough sinks for your school.

Historically, school toilets have been unpleasant places, serving as a magnet for vandalism and bullying. Thankfully, back in 2007, the government introduced the concept of open plan bathrooms. And, as part of this revolution, official guidance from the Department for Education, recommended providing communal handwashing facilities with trough sinks.

Benefits of school trough sinks:

  • Simple to install
  • Attractive
  • Cost-effective
  • Easy to clean and maintain
  • Allow for easy supervision from staff
  • Help to reduce vandalism
  • Help to reduce bullying

Great news, yes!

Without doubt, one of the key attractions of trough sinks in schools is the fact they are so easy to maintain and keep clean.

We construct all our innovative systems using only the most durable and high-quality materials (Corian and steel) – ensuring bathrooms not only look the part, but also have the durability to withstand the rigours of everyday school life and constant use.

The clever design of a trough sink keeps pipework and wires safely tucked away. Our wash trough sinks have streamlined surfaces, meaning bathrooms are not only easier to clean, but safer and more hygienic environments.
