Google "barn doors" for research & ideas & then look to a local carpenter/trim person to avoid freight costs.

thanks for your replies

Check out horse barn doors/sliding barn doors.

There's a wide variety of choices to choose from here: http://rusticahardware.com/barn-door-hardware/

this looks like a custom or semi-custom v-groove 2-panel door. try Trustile doors (www.trustile.com) and check their V-Groove Series. if not a stock product, it is most likely easily customizable.

Have a local carpenter build it...will save tons of money!

I have a cut out "catwalk" in my Family Room, just extra Bonus Bedroom and Bath upstairs....we are thinking about puttin one over the opening of catwalk and painting a distressed color to match Family Room Decor....Then when the kids and grandkids come over, we will be able to open it for easier conversation, etc....Should save us tons on heat and air...especially heat since that goes up! Just a thought!

This is a great place to find hardware in a variety of finishes

For the door try www.trustile.com, the click on door design tool. We have a houzz.com profile too.

Know what type of wood was used to make these doors? Would like to have our finish guy make for us...thanks!

If u plan on painting, why not paint grade pine or maple?

It doesn't look like there is a track on the floor? Would think it would be necessary to keep the door from swinging out? I want something like this to separate bath from Master bedroom, but don't want to put a track on my hardwood floor. Would I have to have a track??

No, you don't need a floor track just the track above shown in the picture.

rockler.com has the hardware for a couple hundred dollars

The door was custom made for the space.

Believe it or not...Home Depot now has doors AND hardware.....and VERY good quality!
