Tile Backer Board vs Drywall: Pros, Cons, and Best Uses

wall renovation

If you’re planning a tiling project, you’ve probably come across the debate: tile backer board vs drywall. As a handyman who’s tackled countless renovation projects, let me break down the pros, cons, and key differences to help you make the right choice for your space. Trust me, understanding this can save you from future headaches—and possibly costly repairs.

Key takeaways:

What Are Tile Backer Boards and Drywall?

First, let’s get clear on what we’re comparing.

Where to Use Each Material

The biggest factor when deciding between drywall and backer board is location. Let’s break it down:

1. Bathrooms and Kitchens

In wet areas like bathrooms, kitchens, or anywhere near water sources, you absolutely need a moisture-resistant material. Tile backer board is the winner here. Why? Drywall, even moisture-resistant varieties like green board, can’t handle consistent exposure to water. Over time, it’ll break down and grow mold.

Backer boards like HardieBacker or Durock are designed to stay intact even when exposed to moisture. If you’re tiling a shower, bathtub surround, or backsplash, don’t cut corners—go with backer board.

2. Dry Areas

For areas where water isn’t a concern, regular drywall is perfectly fine under tiles. Think about a feature wall in your living room or a backsplash behind your desk. Drywall is lighter, easier to install, and more affordable. But remember, it’s still important to seal the tiles properly to prevent any issues down the line.

Common Mistakes to Avoid

  1. Using Regular Drywall in Wet Areas: This is a recipe for disaster. It might hold up for a little while, but eventually, water will find a way in.
  2. Skipping the Waterproof Membrane: Even if you’re using a tile backer board, adding a waterproofing layer is crucial in wet areas.
  3. Improper Fastening: Not using enough screws or the wrong type can cause tiles to crack or pull away over time.
  4. Skipping the Sealing Step: Always seal gaps and seams to prevent water infiltration.

Tile backer board vs drywall FAQs

Can I use drywall instead of tile backer board in a bathroom?
No, regular drywall is not suitable for wet areas as it absorbs moisture and can deteriorate over time.

Is tile backer board waterproof?
While tile backer board is moisture-resistant, it often requires an additional waterproofing layer in wet areas for extra protection.

Which is more affordable: tile backer board or drywall?
Drywall is more budget-friendly, but tile backer board offers better durability and moisture resistance, making it ideal for wet environments.

Can I tile directly over drywall?
Yes, you can tile over drywall in dry areas, but ensure it is properly sealed to prevent adhesive from softening the paper face.

My Recommendation

If you’re tiling in a wet area, always choose tile backer board. It’s worth the extra effort and cost for the peace of mind it provides. For dry areas, drywall is a perfectly acceptable option as long as it’s properly prepped and sealed.

Remember, the key to a successful tiling project is a stable, moisture-resistant foundation. Cutting corners on materials might save you money upfront, but it can lead to expensive repairs down the line. So, plan carefully, follow best practices, and you’ll end up with a tiled surface that looks great and lasts for years.
