Washroom Refurbishment & Hot Water Installation — Educational Facility
Delivering 17 Modern Washrooms & a High-Pressure Hot Water System — All Within an Eight-Week Holiday Window
Schools don’t get second chances. When the new term starts, everything must be finished, safe, and fully operational.
This secondary school in Dulwich SE22 required a complete washroom refurbishment across multiple areas of the building — 17 washrooms in total — along with a new high-capacity hot water system capable of handling heavy, simultaneous use.
The challenge? An eight-week summer holiday window to complete every installation, test every fixture, and hand over a fully functioning system ready for hundreds of students.
Sable Projects delivered on time, on programme, and to full specification.
The School’s Challenge
This educational facility needed:
17 new, modern washrooms
High-pressure hot water across the building
Durable, hygienic fittings suited to high traffic
Concealed services for easy cleaning and reduced damage
A reliable, low-maintenance hot-water system
Installation completed during the school holidays only
The stakes were high:
If the washrooms weren’t completed on time, the school would be unable to open key areas for the new academic year.
They needed a contractor who understood deadlines, compliance, and educational environments.
They needed Sable Projects.
