The material of DIY cabinet doors will depend on the utility of the cabinets and also on the spot where they will end up. For example, if your cabinets are for your kitchen, they will require to be water-resistant because the cabinets will be in contact with water. The wood is likely to soak up all the water and moisture and that can result in your doors caving inwards or outwards. For kitchen or bathrooms, you should opt for pre-treated or water-resistant wood or other materials that won’t soak up moisture. For any other living space, you can opt for whichever material suits you best.
