Premium Washroom Panels

Willis Systems’ P-Max panel system is our premier range panel system designed for dry washroom environments. You can choose from a range of high gloss panels manufactured to suit your requirements. Panels are manufactured from a 18mm ply core or MR MDF core faced with scratch-resistant high gloss laminate and edged using latest PUR technology. Panels can withstand normal wash down cleaning procedures. These panel systems come with HPL faced framework factory made to fit panel units.

Our washroom panel systems are offered as 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).   If you choose a Duct Panel System, 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 bespoke with onsite surveys carried out and CAD drawings produced as part of the package. All Willis IPS units arrive fully assembled with sanitaryware pre-hung, sealed and fitted with easy universal connections that ensures quick and simple onsite hook-up to services.

All units are pressure tested off site therefore removing the onsite interface between joinery & plumbing trades

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

DPS Systems

DPS panel units are a cost-effective alternative to IPS where the customer supplies the sanitaryware.

Modular panel units are pre-hung at works to 25mm WBP plywood sub frames and supplied with loose pre-bonded frame fascias to fit to contractors site framing. Our DPS panels are normally supplied with factory cutouts to suit the customers’ sanitaryware. Onsite installation time is considerably improved as all fixing points and waste holes are pre-drilled.
