How Underlayments Improve Comfort and Durability for Tile Floors

March 17, 2025

If you’re investing in tile flooring, you want it to look great, feel comfortable underfoot, and last for years. While tiles themselves play a huge role in achieving this, there’s another factor you shouldn’t overlook—underlayments. Often hidden beneath the surface, a good underlayment can make all the difference in the comfort, durability, and overall performance of your tile floors.

This blog explores the essential role underlayments play in enhancing tile floors. We’ll Awalk you through the benefits they offer, their various types, and how to choose the right one for your home or business. 

By the end of this article, you’ll understand why underlayments aren’t just optional—they’re a key factor for beautiful, long-lasting tile floors. 

What is an Underlayment? 

An underlayment is the material that sits between your subfloor (the foundation layer of your flooring) and your tile. While it might not be visible, its impact on the overall performance of your flooring is massive. 

Underlayments come in different forms, such as foam, cork, rubber, and cement boards. Some specialize in improving comfort, others in insulation, soundproofing, or durability. Choosing the right type varies based on factors like tile material, room usage, and environmental conditions. 

But why should you care about underlayments when you’re already investing in high-quality tiles? Here’s why. 

Key Benefits of Underlayments 

1. Improved Floor Comfort 

Have you noticed that some tile floors feel harder or colder compared to others? This often has to do with the underlayment—or lack thereof. 

A quality underlayment can offer cushioning, reducing the “hardness” you feel underfoot. Materials like cork or foam create a softer surface to stand on, making the floor more forgiving for extended periods of use. This is especially important in spaces like kitchens where you might spend hours on your feet. 

Additionally, underlayments can provide thermal insulation, creating a cozier floor that stays warm during the colder months. No more icy tiles on winter mornings! 

2. Enhanced Durability and Longevity 

One of the biggest enemies of tile floors is movement. Tiles are rigid, meaning they don’t cope well with the natural shifts of a building or uneven surfaces. This leads to cracks, chips, and loosening over time. 

That’s where underlayments come in. They act as a buffer, absorbing subfloor movement, distributing weight evenly, and preventing tiles from cracking or failing prematurely. A high-quality underlayment doesn’t just support the tiles; it protects your long-term investment. 

3. Moisture Protection 

Moisture is one of the leading causes of tile damage, especially in areas like bathrooms, laundry rooms, or basements. Over time, water can seep beneath the tiles, causing mold and weakening the flooring structure. 

Certain underlayments, such as waterproof membranes, add an additional layer of moisture resistance beneath the tiles. This ensures that water doesn’t damage your subfloor while also preventing costly repairs in the future. 

4. Noise Reduction 

Have you stepped into a room where every footstep echoes loudly, even on tiled floors? Underlayments can help with that. 

Acoustic underlayments, such as rubber or cork, significantly reduce noise by absorbing sound vibrations. They make for quieter homes or work environments, perfect for families, apartments, or office spaces. 

5. Better Adhesion 

Tiles require a strong bond to remain securely in place. Some underlayments, particularly cement boards, provide the ideal surface for improved tile adhesion. This means fewer chances of tiles lifting over the years. 

6. Adaptability Across Subfloors 

Not all subfloors are created equal. Whether your base is concrete, wood, or something uneven, underlayments can smooth out imperfections and create a flat, uniform surface for tiles to adhere to. 

This versatility makes underlayments crucial in addressing subfloor challenges while ensuring your tiles install seamlessly. 

Types of Underlayments for Tile Floors 

Not all underlayments are the same, and choosing the right one depends on your specific needs. Here are some common types and their best use cases:

1. Cement Backer Board 

  • Best for: Bathrooms, kitchens, and other moisture-prone areas. 
  • Why it works: Cement backer boards prevent water damage, provide a durable surface for tiles, and withstand heavy weight. 

2. Foam Underlayment 

  • Best for: Spaces where comfort and noise reduction are key, such as living rooms or bedrooms. 
  • Why it works: Foam offers cushioning and thermal insulation, making tile floors feel softer and warmer. 

3. Cork Underlayment 

  • Best for: Apartments, offices, and spaces requiring soundproofing. 
  • Why it works: Cork absorbs sound and provides a natural, eco-friendly solution for thermal and acoustic insulation. 

4. Rubber Underlayment 

  • Best for: High-traffic areas like commercial spaces or hallways. 
  • Why it works: Rubber adds durability, reduces noise, and creates a sturdy, long-lasting base for tiles. 

5. Waterproof Membranes 

  • Best for: Bathrooms, laundry rooms, and basements with high moisture levels. 
  • Why it works: These membranes offer top-notch moisture protection and help prevent mold growth. 

How to Choose the Right Underlayment 

Selecting the right underlayment comes down to your tiles, your subfloor, and how you plan to use the room. Here’s a quick checklist to help you decide:

  1. Assess Your Environment 
  • Does the room experience moisture (like a bathroom)? Pick a waterproof underlayment. 
  • Need soundproofing? Opt for cork or rubber. 

 

  1. Consider Comfort Needs 
  • For rooms requiring warmth and softness, use cork or foam underlayment. 
  1. Match with Your Tile Type 
  • Heavy tiles like stone or porcelain often pair best with cement backer boards for structural support. 
  1. Evaluate Your Subfloor 
  • Uneven subfloor? Use an underlayment that can smooth out imperfections and offer adhesion. 


Should You Install an Underlayment Yourself? 

The installation of underlayments involves precision. While DIYers with experience may handle foam or cork underlayments, more technical solutions like cement boards or waterproof membranes often require a professional touch. 

Hiring an expert ensures proper installation, which directly impacts the durability and performance of your tiles. Think of it as an investment in peace of mind. 

The Bottom Line – Don’t Skip the Underlayment 

Underlayments are about more than just elevating comfort—they’re your first line of defense against tile failure, noise, and moisture. Skimping on one might save you money upfront but could cost you more in the long run with repairs, replacements, or discomfort. 

We highly recommend taking a thoughtful approach when selecting your underlayment. After all, a strong foundation ensures your tile floors stay stunning, functional, and durable for years to come.

When it comes to renovating or designing a space, the type of tile you choose can make or break the aesthetic and durability of the final output. Whether you're picking out tiles for your floors or your walls, not all tiles are created equal. With countless materials, finishes, and styles available, understanding the difference between wall and floor tiles is the first step to making a choice that compliments both function and design. This guide will walk you through the basics of tile selection and help you ensure that each surface, whether it’s your kitchen backsplash or living room floor, is dressed to perform and impress. The Basics of Tile Designation Before we get into the nitty-gritty, here’s a quick overview of how wall and floor tiles differ. Both serve distinct purposes, so manufacturers design them with specific features to suit the job at hand. Floor Tiles Purpose : Floor tiles are designed to handle wear and tear from foot traffic, furniture, and the occasional accidental drop of an object. Durability : Typically made to be thicker, tougher, and more resistant to impact and moisture compared to wall tiles. Slip Resistance : Many floor tiles are designed to minimize slipping, especially in areas prone to moisture like bathrooms and kitchens. This is achieved through textured finishes or anti-slip ratings. Wall Tiles Purpose : Wall tiles primarily serve aesthetic purposes, although they do protect walls from splashes, stains, and damage. Thickness : Wall tiles are thinner and lighter than floor tiles, making them easier to install on vertical surfaces. Finish : They often feature glossy or smooth finishes, ideal for reflecting light and creating clean, slick designs. Knowing these differences is key to understanding why you shouldn’t use wall tiles on the floor (trust us, they won’t last) and why it’s perfectly fine to use floor tiles on walls (but keep an eye on their weight). Materials for Floor and Wall Tiles The material of your tile plays a huge role in determining its suitability for a particular surface. Here’s a breakdown of common tile materials and their best applications. Ceramic Tiles Best for : Backslashes, bathroom walls, and low-traffic floors (e.g., powder rooms). Why : Ceramic tiles are lightweight, budget-friendly, and available in a wide range of designs. While they’re resistant to moisture, they may lack the toughness needed for high-traffic floors. Porcelain Tiles Best for : High-traffic floors, bathroom floors, and walls. Why : Porcelain tiles are denser and more durable than ceramic tiles. They can handle heavy foot traffic, are highly water-resistant, and can even mimic natural materials like stone or wood. Natural Stone Tiles Best for : Living room or patio floors, accent walls, and fireplace surrounds. Why : Stone tiles like marble, granite, and slate exude luxury and can elevate any space. However, they require regular sealing to maintain their appearance and durability. Glass Tiles Best for : Walls, backsplashes, and decorative accents. Why : Glass tiles are perfect for adding a touch of elegance and creating reflective, light-enhancing surfaces. However, they’re not suitable for floors due to their fragile nature. Cement Tiles Best for : Statement floors, patios, and accent walls. Why : Known for their bold, artistic designs, cement tiles are durable and can create a striking impact. They do require regular maintenance to prevent staining. How to Choose the Right Tile for Your Floor When selecting tiles for your floor, keep these factors in mind to ensure both functionality and longevity. Durability Is Key Floors take a daily beating, whether it’s from dragging furniture, constant foot traffic, or spills. Opt for tiles with high PEI (Porcelain Enamel Institute) ratings, which measure a tile’s resistance to abrasion. For heavy foot traffic areas like kitchens, hallways, or bathrooms, go for a PEI of 3 or higher. Prioritize Slip Resistance For areas prone to moisture, like bathrooms or outdoor patios, choose tiles with textured surfaces or ones rated for slip resistance. Look for tiles with COF (Coefficient of Friction) values above 0.6 for safety in wet conditions. Match Style with Function Floor tiles come in various patterns, textures, and finishes. While aesthetics matter, it’s equally important to ensure the tile you choose can withstand the demands of the space. For instance, glossy tiles might look tempting, but they can be slippery and prone to scratches in high-traffic areas. Consider Maintenance Natural stone tiles like marble create stunning floors but require regular sealing to prevent damage and staining. If you’re looking for a low-maintenance option, porcelain or ceramic tiles fit the bill perfectly. How to Choose the Right Tile for Your Walls When selecting wall tiles, the focus often leans more towards aesthetics. That said, functionality shouldn’t be overlooked completely. Light, Bright, and Beautiful A glossy finish on wall tiles can help reflect light, making smaller spaces like bathrooms or kitchens feel larger and brighter. This is especially important if you’re aiming for a clean and modern look. Think About Weight If you’re contemplating using floor tiles on walls, make sure your wall can support the additional weight. Consult with a professional installer to avoid mishaps. Go Bold with Patterns and Textures Unlike floors, walls are less prone to wear and tear, so you can have more fun experimenting with bold colors, intricate patterns, or textured finishes. Think Moroccan zellige tiles for a touch of artisanal charm or metallic tiles for a sleek, industrial vibe. Highlight Key Areas Using decorative or mosaic tiles to create a feature wall or a statement backsplash can transform a functional space into a visual masterpiece. Common Mistakes to Avoid When choosing tiles for your home or commercial space, avoid these common pitfalls to make the most of your investment. Ignoring Grout : Grout lines are often an afterthought, but their color and width can dramatically impact the look of your tiles. Opt for a grout that complements the tile design while ensuring it’s easy to clean. Overlooking Coefficient of Friction Ratings : Glossy or smooth floor tiles might look trendy, but they can pose safety risks in wet areas. Don’t compromise on slip resistance. Using Wall Tiles on Floors : Wall tiles aren’t built to handle foot traffic and will crack or chip when used on floors. Elevate Your Space with the Perfect Tile Choosing the right tile for your floor or wall doesn’t have to be a daunting task. By understanding the unique requirements of each surface and considering the material, durability, and aesthetic appeal, you can confidently select tiles that enhance both the beauty and functionality of your space. Whether you’re renovating a bathroom, designing an outdoor patio, or creating a feature wall in your living room, there’s a perfect tile out there waiting for you. And with the right choice, every inch of your space can shine.
