I had them installed by an experienced handymancabinet maker. He also made the doors per my design. It took him about an hour to install plus, he had to get creative with the bottom of the door guides.  He had to make his own guides with much taller and sturdier metal.  I love the end result. Although, some people wont like how much space is left between the doors and wall and between the doors themselves.  This covers the direct view of my shower so, if no one is purposely trying to look in then it works for privacy.  Would buy again.
