Laying Timber Flooring Over Tiles: The Core Concept Explained
Planning a renovation often means the project is put on hold after giving thought to tearing up old ceramic or porcelain tiles. Removing tiles is known as being dusty, noisy and very labor intensive. It’s often necessary to hire specialized equipment, install plastic dust barriers around the house, and prevent any damage to the concrete foundation.
Timber flooring avoids this nightmare altogether when placed on top of tiles. Rather than ripping out the floor, the existing tile floor will be used as a subfloor under your new timber floor.
But, it’s relatively easier than just placing wood on ceramics. This method will only work if the tiles are in good condition. They need to provide a solid, level surface. The most frequently used and effective solution is the “floating floor”. High quality Engineered Timber Flooring Melbourne is click fitted over a special acoustic and moisture barrier subfloor. The underlay is placed directly on the tiles, it acts as a cushion and also helps to guard the new wood from any coldness or dampness coming through any old grout line.
Timber Flooring Over Tiles Pros and Cons
It’s crucial to consider the pros and cons of this type of installation before making a commitment to ensure it suits your home.
The Pros
- Huge Cost Savings: Tile removal can be one of the more expensive stages of a flooring renovation, especially when demolition and waste disposal are involved. Keeping the existing tiles allows you to invest more of your budget in premium timber flooring instead.
- Quick Project Timeline: If you need to remove the tiles, that process can take several days, plus the time it takes to have the slab ground to remove the tiles and then allow it to settle, which can take a week or more. When the floor is installed over tiles, the new floor can be installed in one or two days.
- Zero Demolition Dust: Tile dust is a very fine and pesky dust. It enters vents in air conditioners, attaches to walls and finds its way into cupboards for months on end. Avoiding demolition saves your home from dust and noise during the remodeling process.
- Added Insulation: Tiles are known to be cold under foot in Melbourne winters. You can layer an underlay and real timber on top, and the room will have better thermal and acoustic insulation, while being warmer and quieter.
The Cons
- Increased Floor Height: This is the most significant drawback. Underlay and timber boards will increase the height of your floor by approximately 15mm-20mm.
- Door & Skirting Adjustments: Internal doors will typically need to be removed from their hinges and the bottom of the skirting cut out to prevent them from scraping the floor due to the height of the floor. Also, the skirting boards might be a little shorter or you might have to make use of scotia beading all around them to cover the gaps of expansion.
- Transition Issues: If you are only laying a timber floor over tiles in one room then it will be higher than the floors of the adjacent rooms.
Attention to installation of transition strips or ramps is needed to avoid tripping hazards.
Timber Flooring Over Tiles Cost in Australia
It is essential to understand the financial aspects of the project. One of the biggest advantages of installing timber flooring over existing tiles is avoiding the cost of tile removal and disposal. Demolition can add a significant amount to the overall renovation budget, so installing over the existing surface can often be a more cost-effective option.
If you decide to install timber flooring over tiles, your budget will mainly be allocated to the following:
- Preparation (Levelling): If the existing tiles have deep grout lines or an uneven surface, a professional may apply a self-levelling compound to create a smooth and stable base before installation.
- Underlay: A high-quality underlay with a built-in moisture barrier is recommended to improve comfort, reduce noise, and protect the flooring from moisture.
- Cost of the Boards: The overall cost will depend on the type, quality, timber species, and finish you choose. Premium engineered timber flooring typically requires a higher investment than standard options.
- Installation Labour: Professional installation costs vary depending on factors such as the installation method, the size of the area, and the condition of the existing floor.
By eliminating the need for demolition, many homeowners find they can allocate more of their budget towards higher-quality timber flooring while still keeping the overall project cost under control.
Common Problems and Costly Mistakes to Avoid
A professional can do it easily but DIYers can fall into traps that can shorten the useful life of their new floor. When installing over tiles, be sure to avoid these fatal errors:
Not removing “Hollow” or Loose Tiles
A good house can’t be constructed on a bad foundation. All individual tiles should be inspected prior to laying any timber. Use a screwdriver to tap on a tile that sounds hollow, the adhesive under the tile has failed. The new floor will bounce, squeak and ultimately fail if laid over loose tiles. Before you start ensure that any loose tiles are broken out and the hole filled with rapid set levelling cement.
Do not skip the flatness check
The floorboards are made of timber and are stiff. When the new floor boards are installed if the tiled floor dips or bows, the floor boards will bend upon walking on them, creating a tremendous amount of stress on the locking joints. Usually, the subfloor should be level to within 3mm over a distance of 3 metres. Always use a long spirit level to ensure that your tiles are flat (even if they look level)
When there is no Moisture Barrier, forget about it.
Usually, ceramic tiles are watertight, but the grout lines are porous. With time, moisture may gradually work its way up through the grout. However, if wood is laid directly on the tiles without a specific vapour barrier the moisture will lead to cup, warp and mould in the wood. Always use a high quality moisture barrier as the first layer.
How to Lay a Timber Floor Over Tiles Correctly
If you want the job to look flawless and last a lifetime, proper preparation is non-negotiable. Here are the golden rules for ensuring your installation goes smoothly:
-
Clean and Degrease the Tiles: Decades of mopping, spills, and floor polishes leave an invisible residue on tiles. If you need to use a levelling compound, it will not stick to a greasy floor. Scrub the tiles thoroughly with a heavy-duty degreaser and let them dry completely.
-
Use a Self-Levelling Compound: If your tiles are heavily textured (like slate) or have very deep and wide grout lines, an underlay will not be enough to bridge the gaps. You must apply a primer followed by a thin layer of self-levelling compound to flood the grout lines and create a smooth, glass-like surface.
-
Plan Your Doorways First: Before you lay a single board, calculate your new floor height. Check every door that opens into the room. If they need to be trimmed, it is much easier to do this before the beautiful new timber is down, preventing accidental scratches from power tools.
-
Choose the Right Wood Profile: Solid timber must typically be nailed or glued directly to a subfloor, making it very difficult to install over tiles. Therefore, floating engineered timber is the superior choice for this specific application. It offers the exact same visual aesthetic as

FAQs
Can you lay wood floorboards over tiles without removing them?
Yes, you can lay wood floorboards over tiles as long as the tiles are firmly attached, completely flat, and free of moisture.
Will laying timber flooring over tiles affect my doors?
Yes, adding underlay and timber boards will raise the overall height of your floor by approximately 15mm to 20mm. In most cases, internal doors will need to be removed and slightly trimmed at the bottom to ensure they clear the new flooring.
Do I need a levelling compound before laying a timber floor over tiles?
It depends on your tiles. If the tiles are highly textured, uneven, or feature deep and wide grout lines, a self-levelling compound is highly recommended to create a perfectly flat base.
Is it cheaper to install over tiles rather than removing them?
Absolutely. Timber flooring over tiles cost is significantly lower because you avoid the hefty fees associated with demolition labour, dust extraction, and hiring skip bins for rubble disposal.
