Shower Panel External Corner Trims – PVC & Aluminium

Shower Panel External Corner Trims provide a stylish, professional finish where two bathroom wall panels meet at an outward-facing corner. Designed to conceal exposed panel edges, gaps and imperfections, these finishing trims create a neat transition between adjoining walls while helping protect vulnerable corner joints from moisture.

As well as improving the appearance of your bathroom or shower installation, external corner trims play an important role in waterproofing. When correctly installed using a suitable sanitary sealant, they help prevent water from penetrating behind the panels or reaching the exposed inner core.

This protection is particularly important for plywood and MDF shower panels, as prolonged exposure to moisture can cause the core to swell or deteriorate. To achieve a reliable watertight seal, apply the recommended sealant inside the external corner trim before fitting the panels.

Important Information

Panel Compatibility: External corner trims are available in different sizes to accommodate various wall panel thicknesses. Always check your panel dimensions before ordering to ensure compatibility.

Waterproof Installation: Apply a suitable sanitary sealant inside the trim during fitting to help prevent moisture ingress and protect the exposed panel edges.

Colour Variations: Different trim sizes may be manufactured at separate factories or produced in different batches. Consequently, slight variations in colour or finish may occur.
