Showerwall H-Joiner

Showerwall Joining Strip (H Trim) – 2450mm | Panel‑to‑Panel Joint for HPL Wall Panels

Create a seamless, professional join between Showerwall panels with the Showerwall H Trim Joining Strip. Designed for side‑by‑side or stacked panel installations, this profile allows two HPL panels to meet cleanly while maintaining a strong, watertight seal.

The H‑shaped profile sits flat against the wall surface, with each panel slotting neatly into either side. When installed with Showerwall adhesive and sealed correctly, it delivers a smooth, durable finish ideal for bathrooms, shower enclosures, and wet rooms.

To ensure a fully waterproof installation, Showerwall trims are required on all exposed panel edges, including internal corners, external corners, and end points. Five trim types are available to suit every installation layout.

All Showerwall trims are supplied in a 2450mm length and should be installed using Showerwall sealant for maximum moisture protection and long‑term performance.
