I bought a French door shower from Lowe's and it was installed last Dec. 25, the installer hacked it to pieces with rough edges, uneven doors and I could put my hand under the doors.
Lowe's ordered me a traditional shower door, that one popped when opening the door and it leaked. Ordered another door and Kohler's sent the wrong size doors. I finally got my shower in July, 7 1/2 moths later. This week one of the door guide was loose and I discovered that the bolt threads were stripped and the installer had glued it with silicone.
I also bought a microwave from Lowe's a couple of years ago and discovered 2 months later that the installer only bolted one side so it was hanging down 1/2 inch. Don't ever let Lowe's install anything.
