Curbblocks prevents water damage

Traditional methods of shower installation, no matter how well done, will eventually allow moisture to penetrate the subfloor and surrounding areas. This photo is of a shower after just a decade of regular use by 2 people that was installed by a master tile setter of over 20 years. 90% of showers in homes today, look like this beneath the finish surface. Prevent future water damage by installing Curbblocks product line in your shower. Traditional shower installation methods allow water to seep through grout, tile and cracks. Reaching the subflooring which causes severe damage over time..

Curbblocks, First In Foam. As the original prefabricated polystyrene shower building system manufacturer, has been in business since 2001 and has yet to experience a product failure. Curbblocks was founded and is still operated by Ed Peterson. As a tile setter of over 30 years Ed saw a need for an alternative to forming and pouring solid cement curbs and floors or building shower components out of unstable materials such as wood or Sheetrock. Out of that necessity, our company was born.
Since conception, we have had competitors come and go. While some remain. None have been able to meet the same standard of quality or competitive price point as Curbblocks. Our products are proudly made in the U.S.A. Designed to improve the productivity and profit on all your shower jobs. Curbblocks is your one stop shop for all your prefabricated shower building components. Please feel free to reach out to us with any questions and/or concerns. We appreciate your business.
