Are Bathroom Vanities Waterproof?

Are bathroom vanities waterproof? As experts in everything bathroom related, we’re often asked whether bathroom vanities are waterproof and which types of vanities are best for wet areas like your bathroom.

In this article, we’ll answer the question: are all bathroom vanities waterproof and what you need to know to ensure your vanity is as water resistant as possible.

Are All Bathroom Vanities Waterproof?

While vanities are frequently used in bathrooms, it’s important to note that they are not always waterproof. In fact, depending on the type of bathroom vanity you choose and the material it is constructed from, it may be the one area within your bathroom that is susceptible to water damage.

What Are Some of the Most Common Bathroom Vanity Materials?

Some of the most common bathroom vanity materials are:

  • Plywood
  • MDF
  • Solid wood
  • Particleboard

However it is important to note that these particular types of materials are water resistant – as opposed to waterproof. This means your vanity will be more prone to water damage if you opt for these types of bathroom vanities.

What Bathroom Vanities are Waterproof?

PVC is the one material that is completely waterproof and will not require any additional measures when installing a bathroom vanity made from this material. Other types of vanities that are more water resistant and less likely to be prone to water damage include stone or tile.

How and Why Do You Waterproof Your Bathroom Vanity?

Even though the wood-based materials commonly used for bathroom vanities are not waterproof, it is possible to waterproof your bathroom vanity. You can do this yourself but if you really want to ensure your bathroom vanity is as water resistant as possible and not vulnerable to water damage, it’s probably best to engage the assistance of a waterproofing professional.

Some of the other reasons you may waterproof your bathroom vanity include:

Safeguards Your Materials

Waterproofing is the best way to safeguard your bathroom vanity (and the materials from which it is made) from water damage. This is something we would recommend you do even on products that are advertised as being water-resistant, especially if it is wood-based and prone to expansion when wet or exposed to high levels of humidity.

Prevents Moisture & Mould

Even though you may not see it, if your bathroom floor is constantly wet, it’s likely that your bathroom vanity is being exposed to potential damage. The best way to circumvent this issue and prevent moisture or mould build up on your bathroom vanity is to waterproof it.

Once mould gets into your bathroom and your bathroom vanity specifically, it can be difficult to remove and may even cause other major problems both structurally and to the health of yourself and your family.

Prevents Corrosion & Concrete Cancer

Corrosion and concrete cancer is caused by water leaks. Once this exists in your bathroom and your bathroom vanity, you could be looking at a major structural concern. That’s why it’s best to ensure your bathroom is correctly and professionally waterproofed when choosing a bathroom vanity that is not completely water resistant.
