I want to thank you for the responces. I'm learning so much on this forum! SarsChlos...I wanted better airflow in the closet and thought the louvers would help. About 2/3 of the closet will be DH's work clothes, the other will be office files. This room is next to the main bathroom and will function as an office, reading room, and DH's dressing room. Strange! I know, but it's working for us this way. Annz...right now the bifolds are so clumsy and wobbly when we open them. Of course, if may be because they're 43 years old! I hadn't considered looking for "new and improved" bi-folds. Again, thanks for the good info.

Thanks everyone! I went to the big box and checked out the mdf. And I found " custom" doors that can be ordered in non- standard sizes for a very reasonable cost. So happy I don't have to spend $$$ or time/energy to get what I needed.

maddielee - good question. my current sliders are the same thickness as the doors on my bedroom (all the same not-so-pretty hollow core brown doors). But I think they will be. We renovated my bathroom about a year ago and replaced the bathroom door (that's the door that is about three feet from my closet (sliding doors) I mentioned above) and they are the same thickness as my sliders. (Side note - the current bathroom door is a raised two panel door and will be replaced with whatever doors I end up using for the sliders).

I personally believe every bedroom should have a full length mirror for dressing or at least one in the bedroom hall for all to use. Since the rooms are smaller I think the mirror closet doors are a keeper. Function first. If you really don't like them you can always attach a full length mirror on the back of the bedroom door.
