Interior door - Can't use prehung
I'm almost done redoing our master bath and just realized that since we had to build out one wall a half inch, that a pre-hung door won't have a wide enough jam. I got the guys at the local lumberyard to rip down some 1x6 to the proper width, but now my question is whether I can fasten these directly to the 2x4 rough opening, or do I have to construct the jambs seperately. I appreciate any help. Thanks.

Let me make sure that I understand you -- the wall that you want to install this door in is 1/2" thicker than a standard 2X4 wall (so overall, including the sheetrock on both sides it is 5" thick).
No problem -- you can use a prehung door -- you simply add a 1/2" extention to the jamb on the side away from the door. (This way, the door is still flush with the wall.)

Lefty, thanks for your response. You got it, the wall is 5" thick. I considered doing as you mentioned, but was concerned that the extension may leave a visible seam. If this door was to a basement, or another room where I didn't care about one side of the door looking a little off, I wouldn't mind. But this door is between a bathroom and dressing area, so I'd like to use the jams I got ripped to the proper width. Is this okay, ...or not recommended?

Jamb extensions are the best way to go. If the existing jambs have nice edges, adding extensions is pretty simple. You can use filler on the seam, sand it smooth, prime and paint.
Make sure the extensions are the same thickness as the jambs so everything fits in the rough opening and you can still use shims for the installation.

Thanks for everyone's help. I'm sticking away from the extensions because I've seen them done, and I find that you can still see a seam, slight as it may be. I'd rather use a single piece of lumber for the jambs. I actually found a great step by step with pictures on Hammerzone.com. They built a custom hung door that will suit my needs exactly. Thanks anyway.

Understand that I am strictly a diy'er but when i have done extension jambs i have offset them leaving a 1/4" or so reveal rather than trying to line the extensions up flush with the prehung jam.
i do this with doors and windows. . . I have a 1846 cape and barn with all differnet wall widths so I have doen this a lot with many more to go . . . Have I been doing this wrong?

Hey, that's a cool idea. I use it all the time making cabinets and furniture, but never thought of it for jamb extensions.
As long as it looks OK, why not??
