Hi. I'm looking for a quote for a double sliding shower door, semi frameless, clear glass with clear easy to clean coating, in polished chrome. We'll be using double shower door knobs (x2. Haven't bought them yet but will soon). Shower space is an alcove 60". Do you install? If so, will your quote include the install? Also, so you sell tempored glass shower shelves for shower niches? I need 2 12 inch shelves. Thank you.
