These instructions give you an easy to follow, step by step, pictorial guide to waterproofing your shower recess like a professional in accordance with AS3740. Although comprehensive, this Shower Recess Waterproofing Kit is designed for a standard, basic shower recess of approximately 0.9m x 0.9m base and 2.5 m2 of wall area. It may not constitute a full specification for applications beyond this.
