It depends on the level of refinish you are looking for. If you just want to paint them, it is not hard at all and can be a relatively easy DIY project. However, if you are looking to sand and refinish them completely, that will be a more difficult project.

There is no easy answer to this question. It can be hard to refinish kitchen cabinets, or it can be easy, depending on the level of experience and skill of the person doing the refinishing. In general, it is a pretty involved process, and it takes a lot of time and effort to do it properly. That being said, there are plenty of resources available online that can walk you through the process step-by-step. So if you're up for the challenge, then go for it! Just make sure you research and plan ahead so you know what you're getting yourself into. Good luck!
