Product Description
Supreme White Concealed-Waste Shower Tray
The Siena Supreme rectangular shower tray combines a clean white stone-effect finish with an ultra-low profile and a discreet concealed waste positioned along the lower edge of the tray.
Rather than placing a conventional round waste within the main showering area, the drainage system is hidden beneath a coordinated white cover. This creates a cleaner, more continuous surface and gives the tray a refined architectural appearance.
The textured surface adds subtle natural stone character while helping to improve grip underfoot. Its crisp white finish keeps the shower area feeling bright and spacious and coordinates easily with chrome, black, brushed brass, brushed bronze, brushed nickel and gun metal fittings.
Manufactured from durable stone resin, the Supreme tray provides a strong and substantial foundation for shower enclosures and walk-in screens while maintaining a slim, contemporary appearance.

Designed Around the Detail
A discreet waste that does not interrupt the design
The drainage point is positioned discreetly along the lower edge of the tray and concealed beneath a matching white cover. This keeps the main showering surface visually clear while directing water towards the integrated drainage system.
Cleaner Appearance
No exposed round waste within the main tray surface.
Coordinated Finish
The concealed cover blends neatly into the white tray.
Low-Profile Installation for Modern Bathrooms
Available in a selection of rectangular sizes, the Supreme white shower tray can be paired with shower enclosures, sliding doors and walk-in screens of the corresponding dimensions.
Its ultra-low 25mm profile helps create a sleek showering area and can be installed directly onto a suitably prepared floor or recessed where the floor construction and installation method allow.
The concealed drainage system keeps the waste positioned discreetly at the lower edge of the tray while helping water flow away efficiently. The tray must be installed with the correct falls, drainage connection and complete support beneath its surface.
Please review the technical drawing and installation instructions before ordering or fitting. Installation should be completed by a suitably competent installer in accordance with the manufacturer’s guidance.
