Can You Lay Flooring Over Tiles? Floating, Hybrid & Laminate Guide

Ripping up old tiles is loud, dusty and adds cost to any renovation, so it is no surprise that one of the questions we hear most is: can you lay new flooring over tiles? The honest answer is that it depends on the type of floor you choose, the condition of the tiles underneath and how much risk you are willing to take on.

In this guide, Roman Miller from LKV Flooring explains when a floating floor over tiles works well, why glue-down timber over tiles is a gamble, what to check before you start, and how the cost of removing tiles compares with the cost of getting it wrong.

Quick answer

Yes, you can usually lay a floating floor over tiles, including hybrid, laminate and floating engineered timber, as long as the tiles are firmly bonded, flat and free of cracks. Glue-down timber over tiles is not recommended, because the adhesive may not bond to the glazed surface and timber movement can pull the old tiles loose. Always allow for the extra floor height at doors, kitchens and transitions.

• 8 to 21mm: Height added depending on the new floor
• $20 to $55: Typical cost per m² to remove floor tiles in Brisbane

Tile removal cost range based on 2026 Brisbane pricing guides. Your quote will depend on tile type, bedding method and area.

Which Floors Can Go Over Tiles?

Not every floor behaves the same way on top of tiles. The key difference is whether the new floor floats independently or is bonded to the surface below.

Every installation still depends on the condition of the tiles underneath.

Laying a Floating Floor Over Tiles

A floating floor is not fixed to the surface below. The boards lock to each other and rest on an underlay, so the tiles simply act as a firm, flat base. That is why floating floors over tiles are the most common and lowest-risk option.

Hybrid over tiles

Hybrid is the easiest choice. Its rigid core bridges small imperfections, and many products have an underlay already attached, so no extra layer is needed. Explore our hybrid flooring installation.

Laminate over tiles

Laminate floats over a foam or acoustic underlay with a built-in moisture barrier. It is slightly less forgiving than hybrid, so flatness matters more. Learn how we handle laminate installs.

Floating engineered timber

Click-together engineered timber boards can also float over tiles on the right underlay. Check the board thickness first, because it adds more height than hybrid or laminate.

Underlay still matters

Even over tiles, use the underlay the flooring manufacturer specifies. Never add a second underlay beneath a plank that already has one attached.

Why floating works

Because the new floor and the tiles are not glued together, each layer can move on its own. This independence is what protects both the old tiles and your new boards, and it is the main reason floating installations over tiles have such a good track record in Brisbane homes and apartments. Seasonal expansion in the new floor is absorbed by the perimeter gap, not passed down into the old tiles.

Why Glue‑Down Timber Over Tiles Is Risky

A glued engineered or hardwood floor has a lovely solid, quiet feel underfoot, which is why some homeowners ask for it over tiles. Professional installers generally advise against it, for four reasons.

1. Unknown tile adhesion. Nobody can see how well the original tiles were bonded, what adhesive was used, or whether some are already drummy.
2. Movement forces. Timber expands and contracts with Brisbane’s humidity, the same movement that causes gaps between floorboards. Flexible flooring adhesive transfers that movement into the tiles and can lift them off the slab.
3. Poor bonding to glazed surfaces. Tiles are sealed and non-porous, so adhesives and moisture barriers can struggle to grip, leading to hollow spots and clicking underfoot.
4. Warranty problems. Many installers will not guarantee a glue-down floor over tiles unless the owner accepts the risk in writing.

The real cost of cutting this corner

Picture a $50,000 supply and install project laid straight over old tiles. If the tiles start lifting two years later, the fix means removing the new timber, breaking out the tiles, preparing the slab and paying for new flooring again. A shortcut that saved a few thousand dollars can end up costing far more than the original job.

What to Check Before Laying Flooring Over Tiles

Before any floor goes over tiles, a good installer inspects the existing surface. These are the checks we carry out at a site inspection.

• Loose or drummy tiles. Tap across the floor. A hollow sound means the tile is no longer bonded and should be removed and patched.
• Cracked or lifting tiles. Movement in the tiles will carry through to the new floor.
• Flatness. Most floating floor manufacturers require the base to be flat within a tight tolerance, commonly around 3mm over 3m. High spots are ground back and dips filled.
• Deep grout lines. Wide or sunken grout joints can telegraph through thinner floors and may need filling with a levelling compound.
• Moisture. Tiles on a ground-level slab can hide rising moisture, so a moisture barrier underlay is still important.
• Wet areas. Bathrooms and laundries need waterproofing that floating floors cannot provide, so these rooms are usually best left tiled.

How We Install a Floating Floor Over Tiles

When the tiles pass inspection, the installation follows a careful sequence. Skipping any of these steps is where most problems with floors laid over tiles begin.

1. Site inspection. We tap-test the tiles, check flatness with a straightedge and measure door, joinery and appliance clearances.
2. Repairs. Loose tiles are removed and the gaps patched, and any cracked areas are stabilised.
3. Levelling. High spots are ground back and low spots or deep grout lines are filled with a levelling compound.
4. Clean and prime. The tile surface is cleaned of grease and dust so nothing interferes with the underlay.
5. Underlay and moisture barrier. The specified underlay goes down, with a moisture barrier on ground-floor slabs.
6. Lay the floor. Boards are installed with the correct expansion gap around walls, cabinets and fixed objects.
7. Trims and transitions. Reducer profiles, doors and skirting or scotia details are finished so the new floor meets every room neatly.

In Brisbane, the humid summer months make the expansion gap and moisture barrier especially important. A floating floor laid tight against walls or without a barrier on a ground slab is far more likely to peak, cup or develop gaps once the wet season arrives.

Floor Height, Doors and Transitions

Laying a new floor over tiles stacks one layer on another, so the finished floor ends up higher. This is often the deciding factor between keeping or removing tiles.

• Doors may need trimming so they clear the new floor.
• Sliding and balcony doors often can’t be trimmed, so a step or ramp may be needed.
• Dishwashers and appliances can become trapped under the benchtop if the floor is raised around them.
• Transitions to rooms that stay tiled need a ramp or reducer profile.
• Skirting may need adjusting. Read our skirting board options explained for the details.

Remove the Tiles or Lay Over Them?

Laying over tiles saves the cost and mess of removal, but removal gives you a clean slab, no height problems and the widest choice of flooring. Here is how the two compare.

Lay over tiles

• No demolition dust or noise
• Lower upfront cost and faster start
• Works well for hybrid and laminate
• Adds floor height at every door and transition

Remove the tiles first

• Clean, inspectable slab underneath
• No height or appliance clearance issues
• Suits every floor type, including glue-down timber
• Removal usually costs about $20 to $55 per m² in Brisbane

As a rough example, removing tiles from a 50m² living area at those rates would cost around $1,000 to $2,750, plus any slab grinding. On a high-value timber floor, that is often a small price for a reliable result.

Older homes: test before you break tiles

Tiles and adhesives in homes built before 1990 can contain asbestos. If your home is older, have the materials tested before any removal work begins.

From our experience on Brisbane renovations, laying a floating hybrid over sound tiles is often the smartest choice for apartments and quick updates, while full timber renovations almost always benefit from removing the tiles first. A short site inspection usually makes the right path obvious. We would always rather tell you a job is better done properly than install a floor we can’t stand behind for the full warranty period, because a floor that fails reflects on everyone involved.

Laying Flooring Over Tiles in Apartments

Many Brisbane apartments have tiled living areas, and floating hybrid flooring over those tiles is a popular upgrade. Most buildings, however, have body corporate rules on acoustic performance, so the underlay you choose has to meet the required rating. Our acoustic underlay guide explains the ratings and testing process.

Common Mistakes to Avoid

• Laying over drummy or cracked tiles without fixing them first.
• Skipping the moisture barrier on a ground-floor slab.
• Ignoring door, appliance and sliding door clearances until installation day.
• Gluing timber straight onto glazed tiles to save on removal.
• Adding a second underlay under hybrid planks that already have one attached.
• Laying a new floating floor over an old floating floor.
