Complete Bathroom Waterproofing Solutions That Last

Every bathroom faces constant exposure to water, which makes waterproofing a critical step. ProLux offers systems that create a waterproof bathroom floor and secure wall protection, giving homeowners peace of mind. From showers and tubs to vanities and wet areas, our bathroom waterproofing membrane helps block water at the source and keep the space safe.

Installing a waterproof bathroom floor membrane not only stops damage but also provides a solid surface for tile installation. A waterproof subfloor bathroom design ensures moisture never penetrates into hidden structures, reducing the risk of structural decay. With these solutions, your bathroom becomes more hygienic, long-lasting, and easier to maintain.
