Standard Washroom Panels

Willis Systems’ P-18 panel system is designed for a standard dry washroom environment. Panels are manufactured from a 18mm core material usually WBP Ply or MR chipboard which is faced with high pressure laminate and edged with 2mm high impact matching PVC edging. Water integrity is ensured by using latest PUR glue technology. Panels can withstand normal wash down cleaning procedures. These panel systems come complete with HPL-faced framework factory made to fit panel units.

Our washroom panel systems are offered as either supply only or supply and fit. Panel units are either fully pre-plumbed as part of an integrated plumbing system (IPS) or as an economical duct panel system (DPS), where sanitaryware is provided by others but panels are fully prepared with fixing holes and apertures at works to enable easy onsite fit of appliances.

IPS Systems

Our fully integrated plumbing system (IPS) is a bespoke sanitary ware washroom system with on site surveys carried out and CAD drawings produced as part of the package. All of Willis Systems’ IPS units arrive fully assembled with sanitary ware pre-hung, sealed and fitted with easy universal connections to ensures quick and simple on site connection to service.

All pre-plumbed units are pressure tested off site, therefore removing the onsite interface between joinery & plumbing trades.

As we are not a subsidiary of a sanitary ware company, we are free and able to use any combination of vitreous china & stainless steel and high tech no-touch IR controls from many leading brands at very competitive rates.

DPS Systems

DPS panel units are a cost effective alternative to IPS where the customer supplies the sanitary ware.

Modular panels are pre-hung at works to 25mm WBP plywood sub frames and supplied with pre-bonded frame fascias. Our DPS panel units are normally supplied with factory cut -outs to suit the  customer’s sanitaryware. On site installation time is considerably improved as all fixing points and waste holes are pre-drilled.
