Bathrooms face some of the most demanding conditions in the home. With high humidity, frequent water exposure, and fluctuating temperatures, the flooring needs to withstand these harsh environments while maintaining its aesthetic appeal. Choosing the right bathroom flooring material is important to avoid mould growth, water damage, and the need for frequent repairs.

While the aesthetic appeal of bathroom flooring is important, durability, moisture resistance, and ease of maintenance are key factors to consider. The material must not only look good but also offer practical solutions that can withstand water exposure over time.

In this blog, we will go through the 5 best flooring materials for Canadian bathrooms, highlighting their pros and cons, cost ranges, installation practices, and maintenance requirements. Additionally, we will address the 2 materials to avoid due to their potential moisture-related issues.

Preparing Your Bathroom Floor for Installation

Before laying tiles or flooring materials, proper surface preparation is crucial. Subfloor preparation plays a key role in the floor’s stability, durability, and longevity. Without a solid foundation, even the highest-quality materials can fail over time. A level, clean subfloor ensures tiles adhere properly, preventing issues such as cracking, shifting, or water penetration. However, preparation doesn’t stop there – adding an uncoupling membrane and waterproofing underlayment is essential for long-term performance.

Subfloor Preparation: The Necessity of a Level, Debris-Free Surface

The subfloor is the surface layer directly beneath your tile flooring, typically made from plywood or concrete. If the subfloor is uneven or dirty, tiles can shift or crack, and water can seep beneath them, causing damage to the subfloor and creating the ideal conditions for mould growth.

• Why It’s Necessary:
  • A clean, level subfloor ensures that tiles adhere properly and remain stable.
  • If the subfloor is uneven, grout may crack, and tiles could become misaligned.
  • A smooth, level base prevents moisture buildup, which is crucial for bathroom floors.
• How to Proceed:
  • Clean the surface by taking out dust, debris, and any old adhesive.
  • Level the subfloor using a levelling compound if necessary.
  • Check for moisture: If there’s any dampness, address it before proceeding.

Uncoupling Membrane: Essential for Long-Term Durability

The uncoupling membrane adds a layer of protection to the subfloor, helping extend the lifespan of your bathroom flooring. It prevents cracks and damage by allowing independent movement between the subfloor and the tiles.

• Benefits of Floorest Uncoupling Membrane:
  • Crack prevention & uncoupling: Protects tiles from cracking by allowing the subfloor to move independently.
  • Waterproof & breathable: Prevents moisture from damaging the subfloor while allowing moisture vapour to escape.
  • Suitable for damp surfaces: Can be used on new, old, or even damp subfloors.
  • Load distribution: Helps to distribute weight evenly and protects against shearing.

Waterproofing Underlayment: Beyond Water-Resistant Tiles

While water-resistant tiles are essential, waterproof underlayment is equally important for a fully protected bathroom floor. This layer prevents water from seeping into the subfloor, which could lead to structural damage, mould, and rot over time.

• Why It’s Important:
  • Tiles alone cannot stop water from penetrating grout lines and settling beneath the floor.
  • A waterproof underlayment, like an uncoupling membrane, creates an additional protective layer, ensuring no moisture reaches the subfloor.
• What Happens If It’s Not Done:
  • Without waterproofing, water can seep through grout lines, leading to mould and rot in the subfloor.
  • This can cause an expensive and time-consuming repair process in the future.
• How to Apply:
  • Use a high-quality, waterproof membrane beneath the tiles, particularly in wet areas like showers or around bathtubs, to create a waterproof barrier

Two Bathroom Floorings to Avoid for Canadian Bathrooms

When choosing bathroom flooring, it’s crucial to avoid materials that don’t handle moisture well. The wrong choices can lead to structural damage, mould growth, and costly repairs. Solid hardwood and carpets are two flooring materials that should be strictly avoided in bathrooms due to their moisture sensitivity and the risk of mould.

Carpet: The “Sponge” Effect

Carpet is highly absorbent, trapping moisture, dirt, and skin cells, creating a breeding ground for mould and bacteria. In a bathroom, where moisture is constantly present, carpets can quickly lead to mildew and mould growth. The fibres retain water, which can eventually damage the subfloor and pose a health hazard. Moisture trapped in carpets often leads to stagnant water, exacerbating the issue.

Solid Hardwood: The Warping Risk

Solid hardwood flooring is not suitable for bathrooms due to its vulnerability to water damage. Hardwood floors expand and contract with high moisture levels, leading to buckling or cupping. High humidity in bathrooms can cause hardwood to warp, resulting in an unstable and unsightly floor.

Health Risks:

Both carpet and solid hardwood are prone to moisture infiltration. When these materials fail, they can promote black mould (Stachybotrys) growth underneath, which is a severe health risk. This mould can spread throughout the subfloor, affecting indoor air quality and causing respiratory issues.

These materials should be avoided to ensure the health and longevity of your bathroom floor.

Checklist for Installation Best Practices 

Ensuring proper installation is vital to the longevity and functionality of your bathroom flooring. The foundation beneath your tiles plays a crucial role in their performance. By following best practices, you can prevent issues like cracking, water damage, or instability in your bathroom flooring.

• Waterproofing Membrane: Use a high-quality waterproofing membrane, such as Floorest uncoupling membrane, to protect the subfloor from moisture and prevent water damage. This layer prevents grout cracking and keeps the floor dry.
• Waterproofing Underlayment: A waterproof underlayment adds an extra layer of protection. It prevents water from reaching the subfloor, protecting it from mould and rot over time. Choose Floorest Uncoupling Membrane for maximum protection.
• Subfloor Deflection: Check for subfloor deflection (bounce) before installation. An unstable subfloor can lead to cracked tiles or grout. Ensure the subfloor is solid and level before proceeding with the installation.
• Tile Adhesive: Use the right adhesive for your specific tile material and size. This ensures proper adhesion, which is essential for stability and durability.

Grout Sealing: After installation, seal the grout to prevent moisture penetration and staining. Regularly inspect and reapply the sealant as needed to maintain its protective function.

By following these best practices, you can ensure a stable, durable, and long-lasting bathroom floor.

Choosing the right bathroom flooring materials is essential for both functionality and aesthetics. Proper installation, including subfloor preparation, waterproofing, and the right tile adhesives, ensures long-lasting durability and prevents water damage. By following the recommended practices, you can protect your bathroom from moisture issues and mould growth.
