Achieving perfectly finished internal corners has never been easier. Wetwall Mermaid Internal Corner profiles create a clean, seamless transition between panels while delivering a reliable, fully waterproof seal – no messy edges, no complicated fitting, just a professional finish you can achieve yourself.

Each profile comes in a generous 2420mm length, giving you plenty to work with. Choose the finish that suits your space: satin anodised aluminium, crisp white, sleek polished silver, or bold signal black (unless otherwise stated).

For a watertight seal that lasts, we recommend pairing your installation with Wetwall Silicone Sealant and Adhesive. It’s the simple secret to a finish that looks great and stays leak-free for years.
