Harry, thank you for taking the time to write to us. We want you to know that we are sorry that you went through that experience and that we are committed to delivering safe products to its customers. All of our glass shower doors are tempered according to strict government and industry standards. The tempering process creates stresses on the glass that allow the glass to withstand greater than normal forces on its surface. Tempered glass, although extremely strong, can break if an end or corner is scratched, damaged, or impacted – these types of things can occur when the glass shower door unit is not installed as directed in the instructions provided with the product at the time of sale. It is uncommon for tempered glass to break, but when it happens, the glass does not splinter into jagged shards; rather, it breaks into small granular chunks to minimize risk to nearby people and property. We make it a point to understand the details of an incident and would love to learn more about what happened. We’ll contact you personally to learn more about the situation and to answer any questions. - Best, Delta Shower Doors Customer Care Team
