        I have stud support on both sides of the walls. Why do I need, or do I need, to still use plastic anchors. Shouldn’t the screws contact the studs for extra support and elimate the need for anchors?

        joef, thank you for your question. Use of the anchors helps provide additional weight load support in addition to protecting the inside of the holes drilled into your tile. ~Best, Delta Shower Doors Customer Care Team

          Answer This Question

          Ricky, thank you for your question. The sliding door can be installed on either side however it is based on your shower head location. The sliding door panel should be installed on the same side the shower head is on for optimal water retention. ~Best, Delta Shower Doors Customer Care Team

                  Great door!
                  This is a great door! It’s a wonderful quality and the goal isn’t too bright which is nice since I was going for more of the champagne bronze Delta color. We had a company install it but it didn’t take them too long. Great size and works well!
                  by
                    The install was quite easy compared to previously instal j ed shower doors. Normally need 2 people to install shower doors but this one was pretty easy doing it myself. Quality was also on point.

                    Looks beautiful
                    I’m very happy with the Delta Commix frameless sliding shower door. The matte black finish looks modern and high-end, and the 5/16” glass feels solid and sturdy. It really upgraded the look of my bathroom. Installation took some time and definitely requires two people, but once installed it looks great and functions well. Overall, a stylish and well-made door with good value for the price.

                      Response from DeltaSupportDec 19, 2025
                      Jvv, 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.

                        Not recommended
                        My contractor recommended and installed this door despite my concerns. The top rail that supports the fixed panel and the barn door style slider, is only attached to the wall with a single screw. This resulted in (with my install), the top rail skewing off plumb, which places undue pressure on the fixed panel. I am pretty sure this is why some people are experiencing the "exploding door" issue. In my case, the contractor (RJL Construction in San Luis Obispo) also installed this over a reversed slope curb and had to remove it. I ellected to have a professional glass company install a custom door because I wasn't comfortable with this one (or their expertise). The contractor refuses to refund me for the door, despite recommending it, purchasing it and disposing of the packaging, so now I am stuck with it. I am usually happy with Delta products but this one has a flaw.

                          White magnet strip
                          I think the door looks great and I love how it looks in our bathroom, HOWEVER... The magnet strip is guarded with white padding which creates a white line from the top to the bottom of the shower door opening. In a light shower, you don't even see it, but our shower and bathroom are dark and it really shows up. Just a preference thing for me but I don't like the look of the white line. There's not a lot of dark bathrooms in the customer reviews so hopefully if you are doing a dark bathroom you find this review so you can decide if you'd be ok with the white strip.

                            It's good. Looks heavy duty but very fragile. We've been very careful with this since we've read some reviews that it could shatter.
