The one important reason why you should choose new cabinet doors because if you want to keep your costs low, you can always consider buying ready-to-use doors which are available in various colors, material and texture. For ease of usage and low maintenance, you can always consider plywood/MDF. However, if you can afford to spend a little more, proper wood like dark cherry wood cabinets would be a lovely option. If you are feeling eccentric and eclectic at the same time (well done, you!) then you can even consider getting rid of cabinet doors completely and instead opt for an open shelf design. That choice, however, will require you to get new cabinets that are more suited to open-frame designs.
In conclusion, a modern and rustic galley kitchen designs are both provided excellent ideas. To choose one, it depends on the individual’s taste. If you like a neat and straightforward design, you might want to pick a modern one. While, if you wish to have natural beauty with some additional decorations, the rustic galley kitchen might be the best choice.
