I would highly recommend this company for your shower door. Brandon was quick to respond to my request for quote. He provided excellent details about the options and prices including pictures, all in text so was very convenient.

GCS Glass & Mirror is the premier company in AZ. Professional staff, outstanding installers. I ordered 3/8" Starphire clear tempered glass, brushed nickel hinges and hardware to match my bathroom fixtures. Emily sent me a detailed invoice with photos of the hardware. This was the finishing touch to the custom bathroom I built. If you want the absolute best GCS will deliver.
