Can You Install Flooring Over Existing Tiles? (Australia Guide)

One of the most common questions we get is whether new flooring can go over existing tiles — and the answer is: usually yes, and it's one of the best renovation decisions you can make. Installing a floating floor directly over tiles saves the significant cost, time, and mess of tile removal — and in most cases, the result is just as good as starting from scratch.

Here's the honest guide from our installation team: what works, what doesn't, and exactly what to check before committing.

The short answer — yes, in most cases

Hybrid flooring, laminate flooring, and vinyl plank flooring are all floating floors — they click together and rest over the existing subfloor without adhesive or nails. This means they can sit directly on top of existing tiles as long as a few key conditions are met.

The main advantages of installing over tiles rather than removing them:

• Cost saving — tile removal typically costs $15–$30 per m² in labour, plus disposal. On a 50m² house you could save $750–$1,500 or more.

• Time saving — tile removal is slow, messy work. Installing over tiles can save days of preparation time.

• Less mess and disruption — tile removal creates enormous amounts of dust, debris, and vibration. Going over the top means a significantly cleaner, faster job.

• No structural disruption — removing tiles often reveals subfloor damage, moisture issues, or uneven concrete underneath. Going over the top avoids discovering — and having to fix — these issues.

The four things to check before installing over tiles

1. Are the tiles flat and level?

The most important check. Floating floors need a flat subfloor to perform correctly — specifically, no more than 3mm variation over 1.8m. Tiles with significant lippage (where the edges of adjacent tiles sit at different heights), or tiles installed over an uneven subfloor, can create problems for a floating floor above them.

Our installers check this with a long straight edge during the free measure and quote. Minor variations (under 3mm) can be addressed with a thin levelling compound or by grinding down high spots. Significant variation needs more substantial preparation work — which we'll factor into the quote.

2. Are all the tiles firmly adhered?

Hollow or loose tiles are a problem. If tiles are moving or hollow-sounding when tapped, there's a risk that the new floor above them will flex slightly at those points over time, potentially causing the floating floor's click-lock joins to stress and fail.

Tap every tile in the area you're flooring before installation. Solid tiles produce a dull, dense sound. Hollow tiles produce a higher-pitched, hollow sound. Isolated hollow tiles in low-traffic areas are generally fine. Large areas of hollow tiles — particularly in high-traffic zones — should be addressed before the new floor goes down.

3. What is the tile condition?

Cracked or broken tiles with sharp edges or height variation can telegraph through to the new floor above over time. Significantly damaged tiles should be repaired or replaced — or removed from the area — before installation. Tiles that are simply old, ugly, or the wrong colour are absolutely fine to go over — this is exactly the scenario where installing over tiles makes the most sense.

4. Will the new floor height cause problems?

Installing a new floor over existing tiles adds height. The total height addition depends on the product:

• Vinyl plank (4mm) — adds approximately 4–6mm to floor height (board + underlay if required).

• Hybrid flooring (6.5mm–9.5mm) — adds approximately 7–12mm to floor height.

• Laminate (12mm) — adds approximately 13–15mm to floor height.

This matters at doorways (the door may need to be trimmed at the bottom), at transitions between rooms with different floor heights, and at kitchen kickboards. Our team will assess all of these during the free measure and quote and advise on any adjustments needed.

Which flooring products can go over tiles?

• Hybrid flooring — yes — our most popular choice for installation over existing tiles. 100% waterproof, floating installation, works beautifully over flat tiles. The rigid SPC core bridges minor tile imperfections better than softer products.

• Vinyl plank — yes — particularly good for installation over tiles in bathrooms and laundries where its thinner profile means less height addition. The flexible core also tolerates minor tile imperfections well.

• Laminate flooring — yes — in dry areas only. Can go over tiles in living rooms and bedrooms with no moisture risk. Not suitable over tiles in kitchens, bathrooms, or laundries.

• Engineered timber (floating) — yes — floating engineered timber can go over tiles. Glue-down engineered timber cannot.

• Solid timber — no — solid timber cannot be installed as a floating floor and cannot be glued to tiles effectively.

Step-by-step: what happens on installation day

When our team installs a floating floor over your existing tiles, here's what the process looks like:

• Subfloor assessment — we check every tile for hollowness, flatness, and condition. Any issues are identified and addressed.

• Preparation — any significantly raised tile edges or joints are ground flush. Minor low spots are filled with rapid-setting levelling compound. The surface is swept clean.

• Moisture barrier (if required) — for installations over tiles on ground-level concrete, we may install a thin moisture barrier as a precaution even though the tiles themselves form a moisture barrier — this depends on the product and the specific conditions.

• Underlay (if not integrated) — a foam or cork underlay is laid over the tiles if the chosen product doesn't have an integrated underlay.

• Board installation — the new floor is installed in the same way as any other floating installation — click-lock boards from the straightest wall, staggered joins, correct expansion gaps at all perimeters.

• Trims and transitions — door trims are undercut or replaced as needed for the new floor height. Transition strips are installed at doorways and between different floor heights.

When tile removal is the right choice

Going over the tiles isn't always the right answer. Here are the situations where we recommend tile removal before installing new flooring:

• Significantly uneven tiles — where the variation is too great for levelling compound to address cost-effectively. Better to start fresh.

• Large areas of hollow tiles — when more than 20–30% of the tile area is hollow or loose, removal is safer than going over the top.

• Height issues at doorways — if the additional height from going over tiles would create problems at doorways that are impractical or expensive to address.

• Glue-down installation required — engineered timber glue-down can't go over tiles — the adhesive doesn't bond properly to glazed tile surfaces.

• You want to heat the slab — if underfloor heating elements need to be installed, the tiles need to come up first.

Can you tile over existing tiles?

This is outside our scope as a flooring installer, but worth mentioning: new tiles can often be installed over old tiles in the same way — with similar flatness and adhesion requirements. If you're considering tiles for your next floor rather than a floating product, consult a tiling specialist.
