Porta Contours in Engineered American Oak are designed for internal use only. We do not recommend installation in zones where water splash or high moisture levels are present, for example shower recesses or applications where a vessel (bath, basin or tapware) is within 75mm of a wall. Installation in wet areas must comply with specified requirements according to AS 3740:2021, and NCC Vol 1 F1.7 or Vol 2 3.8.1. It is important that all edges are sealed with an appropriate sealer and cut outs to install services or other hardware must be sealed to prevent ingress of moisture. Prior to installation in areas of high moisture levels, Porta Contours in Engineered American Oak must be coated with an appropriate water repellent, preservative finish. Refer to Porta Contours Design, Installation and Maintenance Guide for further information.
