My master bath vanity is a golden oak shade with a lot of wood grain showing. I want to change the entire look of the cabinet and take it to a dark brownish black shade/black walnut and diminish the amount of wood grain that shows. I am certain the cabinet doors are solid wood and the body is composite with some kind of laminate covering. I have an identical sample to test on. Thanks for any advice.
The best way to recolor and change the look of your cabinet is by refinishing with a <a href="//www.painters-toys.com/wood-stains/wood-gel-stain.html" target="_blank">gel stain</a>. This is possible as long as the original finish is in good shape; no peeling, flaking or deep stains. Check out <a href="https://www.house-painting-info.com/restain-cabinets.html">Restain Cabinets for a New Look</a> to see what is possible.
This isn't as easy as just painting the cabinet but with some practice I'm sure you will get the hang of it.
