I contacted Shower Door King via Angie's List and Al came out and looked at the shower enclosure and what it would take to replace with a frameless shower enclosure. It involved some detailed trimming of portions of the stone that supported the door but it was done professionally by Tom. The enclosure was installed today and it looks beautiful. The installers, Derrick and Nathan, were professional and courteous and wanted to insure we were pleased with the results. All of the employees I dealt with - Al, Tom, Tracey, Derrick and Nathan, were wonderful to work with and I would recommend them highly to anyone who wants to replace their current shower enclosure with a frameless one.
