 Alterna vs.Ceramic & Stone

Our durable engineered stone construction makes Alterna tiles a perfect choice over stone, ceramic and porcelain:

  • Warmer to the touch than ceramic or stone
  • More comfortable underfoot
  • Easy-to-clean surface resists stains and soil
  • Strong, yet flexible enough to cover subfloor irregularities that can crack ceramic or stone tile

 Flooring Patterns

Our most popular collections are available in multiple-shapes and sizes, so you can create a unique floor pattern that's all your own.

 On the Wall

The natural beauty of Alterna isn't limited to floors! Use Alterna, with or without grout as a decorative backsplash, accent wall or other focal point to bring added style to your space.

*Alterna is not recommended for shower walls, fireplace surrounds or any wall application that exposes it to continuous saturation or temperatures above 300°F.

 Coordinating Grouts

Enhance the authentic look of your Alterna engineered stone with coordinating grout. Choose from a variety of complementary color options to capture the look that's perfect for your home. Available in warm and cool tones, our grout comes ready to use, requires no sealing and is resistant to mositure, stains and cracking.
