When you are shopping to purchase a bathroom vanity you will quickly understand that you will purchase either a solid wood vanity, a solid wood vanity with veneers or a MDF vanity with veneers. You should first decide which type of construction is right for you. It may be that any of the types are acceptable.
A solid wood vanity is just what it sounds like. It’s wood and it will last a long time and stand up to more harsher conditions in the bathroom. Please know that because it is wood, it may also expand and contract with extreme moisture. Wood is also one of kind. It comes with all the natural imperfections like knots, veining and even discolorations. This is neither a positive or a negative. It’s a personal preference. Wood will also cost more so keep your budget in mind.
A solid wood vanity with veneers has a wood construction base but then it is covered by a veneer which is a thin decorative covering of fine wood applied on top of the wood (or MDF). It is used to improve the aesthetic of the wood but making it more consistent. Veneers also allow more variations of wood grains and colors.
