These splashback style solid surface wash troughs are manufactured with a high rear upstand to prevent spills and splashes from ruining your school washroom walls. Manufactured from Hi-Macs solid surface material, they offer a mould resistant, durable and hygienic product for communal hand washing.

These composite resin hand washing trough sinks are designed to sit on your vanity unit, which offers a strong installation with all the pipework concealed. The troughs can also be supplied with wall brackets, and a fascia panel for wall mounting. Designed for use with wall mounted taps which leave the trough easy to clean and very hygienic. The trough sinks are available in a range of colours - ideal for primary schools and nurseries.


Made to order, typically 3 to 4 working weeks
