Usage Tip:

Install the VaporTec XPS shower curb on a level base, making sure to achieve full coverage when bonding to the subfloor, adjacent walls and shower pan. Use a compatible modified thin­set to bond the curb to the subfloor, walls and pan. Field-cut curbs cleanly with a utility knife or chop saw, and clamp securely until set. Inspect the joint between curb and pan, and reinforce or seal per the shower waterproofing system manufacturers requirements.

If the installation includes multiple curb units joined together, apply a compatible sealant such as VaporTech Sealant or Ardex TLT 700 Sealant or membrane tape at the joint to maintain waterproof continuity.

Introducing the VaporTec XPS Waterproof Tileable Shower Curb

Designed to meet the rigorous demands of modern tile installations in wet environments, the VaporTec XPS shower curbs deliver durability, dimensional stability and full tile-ready surface in one integrated component.

Performance at a glance:

  • Engineered from a closed-cell XPS (extruded polystyrene) core, the unit is waterproof & vapor-tight, minimizing risk of moisture intrusion behind the curb assembly. 

  • Tile-ready surface: With a fiberglass-reinforced polymer-cement coating, the curb provides a high-bond surface for tile adhesive, ensuring strong and consistent adhesion in tile and stone applications. 

  • Lightweight yet rigid: Optimized for handling on the jobsite with minimal weight but high structural stability—making installation faster and safer. 

  • Purpose-built sizes: Available in multiple standard lengths (e.g., 4.5″ × 3″ cross-section with 48″, 60″ or 72″ lengths) to match common shower curb dimensions and reduce field-modification time. 

Key Specifications:

  • Material: Closed-cell XPS core with polymer-cement / fiberglass-mesh coating

  • Profile (typical): 4½″ wide × 3″ high

  • Lengths available: 48″, 60″, 72″ 

  • Finish: Tile-ready surface — accept tile mortar and large-format tile directly

  • Application: As the raised curb / perimeter barrier in tile-lined showers, compatible with waterproof membranes, vapor barriers and standard membrane systems
