Typically, the type of finishing you put on your kitchen worktop should be dependent on the functionality of the kitchen. I think for a more decorative unit, a natural or stained finish will be more suitable for that purpose since it would not be getting much active use.
If you like to cook and spend time in the kitchen, I will suggest you choose practical finishes like semi-gloss paint, melamine, and lacquer. They are affordable and can withstand spills, cleaning, and time.
You can also opt for granite worktops and save yourself the stress of searching the internet for how to remove stains from wood. I recommend you settle for a finish that will not only be friendly on your pockets but also easy to maintain.
Thankfully there is no shortage of options online when it comes to this. Stores like diyluxurykitchens.co.uk offer worktops like this and you can get them without even leaving your home.
