No experience with those doors, but we faced a similar dilemma. We wanted slab doors--and we wanted solid wood. We were directed away from slab doors by GC because of the potential for warping, and ended up choosing shaker doors with slab drawers (Wellborn Forest).

It is by design, to avoid warping, that door panels are constructed by joining pieces, rather than using a single slab. If the possible color/grain variations bother you, you can go for door panels with veneer overlay or go for man-made materials. Need to ensure there is some play in the door frame, for the panels to "float" and adjust for temperature fluctuations.

We just had our slab doors put in. Love them! Our kitchen designer recommended that we go with the wood veneer vs. solid wood to avoid any potential warping issues. He made the same recommendation for the cabinet boxes, i.e., particle board instead of solid plywood.

Great kitchen abbeycat9900!
I love the look of the slab door also. In my opinion, the finish on the durasupreme doors looks better than the thomasville doors. But, to get the veneer in durasupreme, it's almost 25% more! Ouch!! I wonder how often the wood slab doors warp? Its it inevitable that the all wood slab door will warp?

I wanted slab doors because I like the clean look. When we started cabinet shopping, none of the cabinet makers we spoke to in the area we live in (Canadian prairies) would give any warranty on slab doors that were solid wood. They all stated that climate considerations here could result in warping. Since they stood to make more money off us if we went solid wood, I am guessing they were being honest and maybe speaking from experience. We went with veneer. One thing our KD told us to watch for during our cabinet shopping was to make sure that there was a solid wood trim around the door edges for veneered doors. With veneer doors, little bumps on door edges is more likely to result in damage (chipping of veneer etc.) whereas the solid wood edge protects the veneered area. Of the 6 places we checked out cabinets, 4 made the cabs with a solid wood edge and 2 didn't. That is one consideration I would not have thought of if our KD didn't mention it.

It definitely sounds like I would be better off with veneer...
That's a great point teapotter! I didn't think of that either! But, I'm sure that a solid wood trim would make a big difference. I live in Michigan, and we have drastic weather changes. I certainly don't want to worry about my new cabinets warping!

Our kitchen designer recommended AGAINST veneer panels because our cabinets are cherry. Cherry is known to change colors as they months pass. She said to stick with all wood to keep the color change uniform. Didn't want to have one color frame, and a different color panel. We went with the all wood, and though it was more expensive and because she only carried one brand that made our style (shaker/mission) in full wood - we went with them. Thomasville, cherry wood, briarwood stain.
