Hi Dianne, thanks for the questions!

Since cherry is the actual wood species used to build the doors, your existing cabinets can't be changed to "cherry," but they could be stained a color that is more similar to what you see on a cherry wood. (The color shown here is "Mocha" but it is only available on Durasupreme cabinets.) Since cherry naturally can have a reddish or brownish color, you often see reddish, reddish-brown, and other darker shades of stain on cherry wood. Cabinets can be re-stained, but it requires much more work (including sanding all the existing finish away) than painting them would.

As far as cost, it is hard to give a cost without knowing the details of your exact kitchen, but cherry does tend to be a bit higher in cost than other common woods, such as maple.

Hope this helps! -Emily
