Tub Surround Waterproofing

Bathtub waterproofing protects your bathroom from one of the most common sources of water damage. By sealing the space around and behind your tub with ProLux systems, you create a barrier that keeps moisture from spreading into walls and floors. Our waterproof bathtub surrounds and wall panels are designed specifically for tubs, giving you lasting protection where you need it most.

Complete Bathtub Waterproofing Systems

Complete Bathtub Waterproofing Systems

The area around a bathtub faces constant exposure to splashes and standing water. Without the right protection, moisture can easily seep into joints and gaps, creating the perfect conditions for mold growth, water stains, and costly long-term damage. That’s why a reliable bathtub waterproofing system is essential to keep your bathroom safe, hygienic, and low-maintenance.

ProLux provides complete waterproofing solutions designed specifically for bath and shower areas. From durable bathtub surrounds to all-in-one tub and shower surround kits, every product is created to make sealing your bathing space simple and effective. Waterproof wall panels are also available, giving you the option to build a strong, watertight barrier that prevents leaks and reinforces the structure around your tub.

By choosing ProLux systems, you get more than just waterproofing, you get peace of mind. A bathtub wall panel system creates a secure base for tile or decorative finishes, while surround kits speed up installation and ensure every corner is properly sealed. The result is a bathroom that not only stays watertight but also looks clean, polished, and built to last.

Why Bathtub Waterproofing Matters for Lasting Comfort

Why Bathtub Waterproofing Matters for Lasting Comfort

  • Creates a sealed barrier behind the tub, which stops splashes and condensation from damaging hidden walls.
  • Secures tub surround seams, which prevents leaks and keeps your bathtub enclosure watertight.
  • Supports waterproof bathtub wall panels, which provide a smooth finish that resists daily wear and water exposure.
  • Reduces mold growth around bathtubs, which ensures a fresher and more hygienic bathing space.
  • Extends the lifespan of bathtub installations, which saves money by protecting tiles, panels, and the structure beneath.

Waterproofing around bathtubs is not just an upgrade, it is a necessity for modern bathrooms. ProLux systems make the process easy, delivering a durable seal that lets you enjoy your bathtub without worrying about water damage.
