OK, so they're not inset, but here are my 33" overlay slab front drawers: My pots & pans drawer is 36" wide. I don't think they look too wide, but then we have a wide room (15').

Would it make a difference if the boxes are nailed, not dove-tailed? Because they are not dove-tailed. My gut tells me it should be fine--I never would have thought "no, we shouldn't do that, it will warp". But what do I know, I'm not a cabinet expert. But, this guy is starting to freak me out. this morning, he said again "these are going to warp". He also told me a spliced drawer front would solve the problem. I really hate that he is making me question this, because after all, I am not the expert, and frankly, neither is the KD (or GC for that matter). I just can't figure out why the cabinet guy is saying this and everyone else (including me) thinks it will be fine. Thanks for letting me vent!

On small drawers, even if there is room for the pull in the center of a 5-piece, it may be awkward to use the pull there on a small drawer. I noticed this in a cabinet show room - the rails made using the pull uncomfortable as they scraped against the backs of your fingers as you reached in to the pull. One of the considerations for us was what was accurate for real Shaker style. In all the historic Shaker furniture (i.e. furniture that was made by Shakers) that I've seen, the drawers are slab and only the doors are 5 piece. They believed in simple design and did 5-piece on the doors because it is more practical for large surfaces with solid wood. It allows for the expansion and contraction of the wood inside the frame with the weather. On the smaller surface of the drawers, slab was practical and simpler. Therefore we only did 5-piece on the doors and the very deep drawers (8" or deeper) and did slab on the smaller drawer fronts. For the large drawers, we put the cup pulls on the top rail of the drawer - I like that look and since these are usually the bottom drawer, it is a more convenient height. Our house is MCM but we didn't want to do slab which would be a bit too simple for our taste (and too like the cabinets that we had taken out) but we still wanted to keep the look simple. A shaker look with slabs for the drawer fronts and a simple 5-piece for the doors fit that.

You said you ordered the Doors wood with MDF panel - that will not eliminate the paint fissures from expansion and contraction - the wood parts will still move. The mdf panel helps because it is not moving but it is not the cure all. I have a company who does doors made of all MDF but put together like a regular door is and while the paint lines are minimal they are not marketing the product as not ever getting those lines. It will still be possible but much less. As far as chipping goes, I think that will happen no matter what the door is made of. Have a conversation with your KD and see what the real deal is and go from there....Maybe they will let you use one of the doors as a test... bang it around, bump it with pots, soak it with water, spill stuff on it and see what you think ( but you should try that with wood too....) Good luck!
