Understanding the distinction between waterproof and water-resistant flooring is important when choosing the most appropriate material for your space. This differentiation holds particular significance in areas susceptible to moisture accumulation, such as kitchens, bathrooms, and basements.

It is also important to safeguard your floors against potential water damage and the proliferation of mold, thereby ensuring their long-term durability and resilience. Ensuring the longevity and performance of your flooring necessitates a thorough comprehension of the unique characteristics and practical implications associated with waterproof and water-resistant options. 

Understanding the Differences

When it comes to choosing flooring materials for spaces exposed to moisture, understanding the disparities between waterproof and water-resistant options is an important step. While both categories offer varying degrees of protection against water damage, they differ significantly in their composition, capabilities, and suitability for different environments.

1. Waterproof vs. Water-Resistant Flooring

At its core, the difference between waterproof and water-resistant flooring lies in their ability to withstand water penetration. Waterproof flooring, as the name suggests, forms an impermeable barrier that prevents water from infiltrating the material, even when subjected to prolonged exposure.

This makes it an ideal choice for areas prone to high humidity, spills, or moisture accumulation, such as bathrooms, kitchens, and basements.

AspectWaterproof FlooringWater-Resistant Flooring

In contrast, water-resistant flooring offers a level of protection against water damage but may not completely repel moisture under extended exposure. While suitable for spaces with occasional spills or moderate humidity, water-resistant flooring may not withstand continuous moisture exposure or flooding events.

2. Practical Considerations for Choosing Flooring

When deciding between waterproof and water-resistant flooring options, several practical considerations come into play.

  • Assess the specific needs and conditions of the space to determine the level of moisture resistance required.

For areas susceptible to frequent water exposure or high humidity levels, such as bathrooms or laundry rooms, opting for waterproof flooring ensures optimal protection against water damage and mold growth. Conversely, in spaces with lower moisture levels or occasional spills, water-resistant flooring may offer sufficient protection while providing more flexibility in terms of material choices and design aesthetics.

Tile Flooring$5 – $15
Concrete Flooring$2 – $10
Vinyl Plank Flooring$2 – $7
Engineered Hardwood$3 – $10
Laminate Flooring$1 – $4
  • Consider factors such as maintenance requirements, installation costs, and long-term durability.

While waterproof flooring often comes at a higher initial cost and may require professional installation, its ability to withstand moisture without compromising its integrity can result in long-term savings and peace of mind.

Concrete Flooring50+
Vinyl Plank Flooring10 – 20
Engineered Hardwood20 – 30
Laminate Flooring10 – 20

On the other hand, water-resistant flooring may offer a more budget-friendly option with easier installation and maintenance requirements, making it suitable for a wide range of residential and commercial applications. 

Waterproof Flooring

Waterproof flooring refers to materials engineered to resist water penetration, effectively preventing moisture from seeping through to the subfloor or underlying structures. Unlike water-resistant flooring, which may offer limited protection against water damage, waterproof flooring creates an impermeable barrier that withstands prolonged exposure to moisture without compromising its integrity.

This is necessary, especially in areas prone to spills, leaks, or high humidity levels, where traditional flooring materials may succumb to water-related deterioration over time.

1. Tile Flooring

Tile flooring is made from ceramic or porcelain materials which are inherently waterproof, thanks to their non-porous nature and dense structure. When properly installed with grout and sealant, tile flooring forms a formidable barrier against moisture intrusion, making it an ideal choice for wet environments such as bathrooms, kitchens, and entryways.

Moreover, the durability of tile flooring further enhances its resistance to water damage, offering longevity and low maintenance requirements. Its smooth surface prevents water from seeping into the subfloor, mitigating the risk of mold growth and structural deterioration. 

2. Concrete Flooring

Concrete flooring has a solid composition and seamless installation which minimizes the opportunities for water infiltration, rendering it highly resistant to moisture damage. In areas where traditional flooring materials may falter, such as basements and garages, concrete flooring emerges as a reliable solution for maintaining a dry and stable environment.

Advancements in concrete sealants and coatings further enhance its waterproofing capabilities, providing an additional layer of protection against water seepage. By sealing the pores and cracks in the concrete surface, these products fortify the flooring system, prolonging its lifespan and reducing the need for extensive maintenance. 

Water-Resistant Flooring

Water-resistant flooring refers to materials that can withstand exposure to water to some extent without sustaining significant damage or degradation. While not entirely impervious like waterproof flooring, water-resistant options provide a level of protection against moisture infiltration, making them suitable for areas with moderate humidity or occasional spills.

1. Engineered Hardwood Flooring

Unlike solid hardwood, which is susceptible to warping and swelling when exposed to moisture, engineered hardwood features a layered construction designed to mitigate these issues. Its plywood or high-density fiberboard (HDF) core provides stability and resistance to moisture, allowing it to withstand fluctuations in humidity levels without compromising its structural integrity.

It often comes with protective surface treatments, such as aluminum oxide or polyurethane finishes, further enhancing its water-resistant properties. These coatings create a barrier that repels water and spills, reducing the risk of damage to the underlying wood veneer.

2. Laminate Flooring

Constructed from multiple layers of synthetic materials, including a moisture-resistant core, laminate flooring has a strong resistance to water damage, stains, and scratches. Its melamine wear layer provides a durable surface that repels moisture and spills, ensuring long-lasting performance in environments prone to moisture exposure.

Furthermore, laminate flooring features a click-lock installation system that creates tight interlocking seams, minimizing the potential for water infiltration between planks. While not entirely impervious to water, laminate flooring offers sufficient protection against everyday spills and moisture, making it suitable for areas such as kitchens, living rooms, and hallways.

Can You make Waterproof floors Water-Resistant (and Vice Versa)?

In certain situations, you may find the need to alter the properties of your flooring, either from waterproof to water-resistant or vice versa, to better align with changing environmental conditions or design preferences. While complete transformation may not always be possible, there are several strategies and interventions that can help enhance or diminish the moisture resistance of your flooring to some extent.

Waterproof Flooring to Water-Resistant

While these strategies may help adjust the moisture resistance of flooring to some extent, it’s important to consider the limitations and potential consequences of altering its properties.

1. Application of Sealants

Sealants are commonly used to enhance the waterproof properties of flooring materials, but they can also be utilized to reduce water resistance. By applying specific types of sealants or coatings to the surface of waterproof flooring, you can introduce a layer that decreases its ability to repel water effectively.

These sealants work by filling in pores and imperfections in the flooring surface, thereby compromising its water resistance.

Flooring TypeRecommended Sealant Types
Tile FlooringEpoxy grout, penetrating sealers, urethane sealants
Concrete FlooringAcrylic sealers, polyurethane sealants, epoxy coatings
Vinyl Plank FlooringPolyurethane sealants, silicone-based sealants
Engineered HardwoodPolyurethane sealants, water-based sealers
Laminate FlooringSilicone-based sealants, polyurethane sealants

However, it’s essential to exercise caution when applying sealants, as improper application or selection of sealant products can lead to undesirable outcomes. For instance, using a sealant that is too heavy or thick may result in an uneven surface appearance or compromise the integrity of the flooring material.

Additionally, frequent reapplication may be necessary to maintain the desired level of reduced water resistance over time.

2. Modification of Installation

Another approach to converting waterproof flooring to water-resistant involves modifying the installation process or materials used. For example, opting for less robust adhesives or sealants during installation can reduce the flooring’s ability to withstand moisture infiltration. 

Similarly, installing the flooring without proper sealing or using techniques that create gaps or seams can increase its vulnerability to water damage.

Water-Resistant Flooring to Waterproof

While it’s typically more challenging to convert water-resistant flooring to waterproof, there are methods and interventions that can help enhance its resistance to moisture to some extent.

  1. Application of Waterproof Coatings

One approach to bolstering the water resistance of flooring materials is by applying waterproof coatings or sealants. These specialized products create a protective barrier over the surface of the flooring, effectively repelling water and preventing it from seeping into the material.
