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 curb is the only prefabricated shower building component on the market that accepts the use of a rubber pan/liner.


Curbblocks, 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.  Curbblocks has yet to experience a product failure. 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.
