The downside can occur when pipes get leaky under the counter and cause damage to the wooden structure. Sometimes it is better to go for a waterproof polyvinyl wall cabinet if water leakage is a risk. Porcelain models are a less popular choice but can still provide an excellent vanity for people looking for this kind. More expensive than the wooden type, the porcelain vanities can offer different style options, making the trade-off evident for some people. Water damage is not an issue with porcelain, either, so that is another factor.
