What natural wood is best for making kitchen cabinets?
I would recommend solid hardwood for kitchen units, especially for making a worktop. Pine and oak are great choices if you want easy-to-find materials. They are also cheap and give your kitchen a warm homey feel.
For a more luxurious look, Cherry and Maple are the better options. While they will cost you a little more than the other wood types, they are cost-effective in the long run. They are quite resistant to nicks, easily cleaned, and get gorgeous with age.
Also I should add that when searching for the best kitchen units for your kitchen, be sure to be conscious of what material will work well with your budget and at the same time, match the aesthetic of the rest of the space.
Online catalogs like those at DIY Luxury Kitchens, for example, are great for this purpose because they prioritize synchronicity, quality and affordability of materials.
