How long does bathroom waterproofing last?

Typically, bathroom waterproofing in Sydney lasts between 10 to 15 years — sometimes longer with proper maintenance and minimal structural movement. However, the lifespan depends heavily on the quality of both materials and workmanship. That’s why CBRS goes the extra mile by installing copper shower trays beneath our tiled floors. These trays act as a durable, built-in backup system, helping to protect the subfloor even if the top layer of waterproofing is ever compromised, offering long-term peace of mind.

What causes waterproofing to fail?

Waterproofing can fail for several reasons — including poor surface preparation, low-quality materials, rushed application, or structural movement over time. Another common issue is damage caused by other trades during the renovation process, particularly between the waterproofing and tiling stages. Even something as simple as dropped tools or foot traffic can weaken the membrane if not properly managed. At CBRS, we protect against these risks by using best-practice methods and installing copper shower trays as an extra layer of defence beneath the tiled surface. This ensures the area remains protected, even if unexpected damage occurs
