The best material to use comes down to personal choice. When you want to make a bathroom vanity, you have many material options. The most common types include solid wood, particleboard, plywood, composite, MDF, and many others.
Suppose solid wood is your choice, then you have to decide from different options under it. Solid wood is the most preferred choice for bathroom vanity units because it is strong, durable, appealing, and comes in many color options. However, it is also the most expensive option available.
For solid wood bathroom vanity units, you can choose cherry, teak, oak, birch, maple, etc. Again, the cost of your bathroom will vary depending on the specific solid hardwood you choose.
