Convert 2' by 7' window to door
We have a 2' by 7' glass panel window in our downstairs bathroom that I would like to convert to a door to our patio and pool area. There is already a concrete slab outside the window, like a step. The current opening can't be made more than 4" wider without removing the sinks, tub surround tile, etc., so we'd like to use the existing opening. I would also like to use some type of tempered glass because the room needs the natural light. Finally, I'd like to be able to lock the door for privacy and security. I need to know where to custom order such a door and how to install it.
