WholePanel Wall Panel Internal Corner Trim

This UPVC trim conceals edges and creates watertight junctions at internal corners with a 2700mm length suited to higher ceiling rooms. Grey finish suits contemporary schemes and stone effect panel installations, disappearing into the installation rather than drawing attention. The 8mm x 8mm profile matches precisely with Whole Panel 8mm panels for seamless visual integration. UPVC construction remains fully waterproof and lightweight, requiring no painting or surface treatment. Installation is simple: apply sealant along the back of the trim into the corner junction to create a durable, watertight seal. The material will not corrode or degrade in bathroom humidity, maintaining appearance and function through years of daily use.
