   I have had some trouble with MDF trim and moisture - jambs and base moulding - but not doors. I believe that if it is well sealed, you should be fine. Also, you should have an exhaust fan in there.

   For the trim, I have gone to the MDF material that is impregnated with PVC. Its water proof.

   the question is how many time do you want to build the doors? 

   instead of mdf, look to a sign shop and get mdo.  It is similar to mdf but made to be outside.  others will have ideas also.

   or leave the big box for wood and get wood from a store like woodcraft. you could use baltic birch that is cabinet grade or veneered plywood for cabinet.

    

   good luck.

   I doubt you'll have any trouble. A lot of commercially made cabinets come through with MDF parts. Moulded thermofoil doors incorporate MDF as the substrate. I've seen the covering peel off but the panel is usually fine. You are taking it a step further by capturing the MDF in a frame-a good plan. In my experience, direct contact with water is what should be avoided. Airborne moisture, changes in climate not as big a deal.

   Good luck,

   The MDF should work fine if it's painted/sealed front and back. 

   If you're doing paint grade cabinets, look into Poplar for your face frames and door rails and stiles.  It's much lighter than MDF or MDO, mills beautifully, and takes paint like a dream.

   Here are some pictures of a bathroom cabinet I did last year.  The panels are MDF and the rails and stiles are poplar.  I pre-primed the panels before I assembled the doors.
