Yes, you can lay hybrid flooring directly over tiles in most Australian homes, as long as the tiles are firmly stuck down, the surface is level within tolerance, and the grout lines aren’t too deep. Skipping a tile demolition saves a day or two of labour and a skip-bin’s worth of mess. The catch: the prep has to be honest, because anything you leave behind under the planks will eventually telegraph through. Here’s how we approach it on site.
Check the tiles before you commit
Walk the floor first. Tap each tile with a metal handle or a knuckle and listen — a hollow tile means the bond underneath has failed, and that tile will rock under foot pressure once a hybrid plank sits on top. Any drummy or cracked tiles need to come up and be patched before you go further. Loose grout is the same story: scrape it out, refill, and let it cure.
- No drummy or cracked tiles — pull and patch any that fail the tap test
- No active moisture — older slab-on-ground tiles can hide rising damp
- Sound grout lines, no crumbling sand-cement joints
- No sealants, polishes or wax residues that would stop a self-leveller bonding
If the tiled floor is in a wet area like a bathroom or laundry and the existing waterproof membrane has been compromised, that’s a different conversation — see our what flooring is waterproof guide for how to handle wet zones properly rather than just covering the problem.
Level the surface — this is where most jobs fail
Hybrid planks are rigid. They won’t follow undulations, and they won’t bridge a deep grout line for long. Run a 2-metre straight edge across the floor in several directions and check for high spots and dips. Most hybrid manufacturers ask for a tolerance of around 3 mm over a 2 m span. Anything outside that, and you self-level.
- Wide, deep grout lines (over 4-5 mm): skim with a feather-finish or a thin self-levelling compound rated for tile substrates
- High spots or lippage between tiles: grind back, or pour a proper self-leveller across the whole room
- General undulation across an open-plan area: a full self-level is faster and more reliable than spot-patching
Whatever product you use, prime the tiles first with a primer rated for non-absorbent surfaces. Skipping the primer is the fastest way to end up with a self-leveller that crazes or pops loose under foot traffic.
Underlay over tiles
Most quality hybrid flooring ranges already have an IXPE acoustic underlay pre-attached to the back of the plank. If yours does, you don’t add a second underlay — doubling up softens the click joints and voids the warranty on most brands.
If your hybrid is one of the few without a pre-attached underlay, use a thin acoustic-rated underlay designed for rigid-core flooring (1-1.5 mm). Anything thicker than 1.5 mm and the joints start moving under load. Tiles laid on a slab generally don’t need a separate moisture barrier, but if you’re in a known damp area or laying over a slab in a renovated downstairs space, a moisture-barrier underlay is cheap insurance.
Lay the planks — what changes when the subfloor is tile
The install itself is the same click-lock process as any other hybrid floor. A few details matter more when you’re going over tiles:
- Stagger your end joints away from grout lines. A plank end joint sitting directly above a deep grout line is the first place a click joint will fail.
- Leave the right perimeter expansion gap — usually 8-10 mm against every wall, every doorway and every fixed object. Hybrid expands and contracts with temperature; pinning it under a skirting that’s already touching the wall causes peaking.
- Direction of lay: long edge of the plank parallel to the longest wall, or to the dominant light source.
Door clearances, transitions and skirtings
Adding hybrid over existing tiles raises the floor height by roughly 6-8 mm depending on plank thickness and any underlay. That’s enough to catch internal doors, especially over carpet thresholds in adjoining rooms.
- Trim the bottom of internal doors before, not after, the floor goes in — it’s far easier to plane a door off its hinges than to reach under a finished floor
- Plan transitions at every doorway: a T-bar to carpet, a reducer to a lower tile, a flush join to another hybrid floor of the same height
- Decide upfront whether you’re keeping existing skirtings (in which case you’ll need scotia or quad to cover the expansion gap) or pulling skirtings off and refixing over the new floor (cleaner finish, more labour)
When laying over tiles is the wrong call
There are a few situations where we’d recommend pulling the tiles up rather than laying over them:
- The tiles are widely drummy or the bond is failing across multiple areas — you’re laying over a slow-motion failure
- The total floor height after install would compromise door swings, kitchen kickboards or appliance heights
- The existing tiles are on a known damp slab without a working membrane — moisture under a hybrid floor will eventually push through the joints
- You’re in a wet zone where the existing waterproofing is unknown — pull tiles, re-membrane, then lay
Cost-wise, is it worth it?
Skipping a tile pull-up usually saves $25-$45 per square metre in demolition and disposal, plus a day or two of trades. Against that, factor in the cost of self-levelling compound and primer if your tiles need it, and the cost of trimming doors and reworking transitions. For most jobs the maths still favours laying over the tiles, but you can sense-check the full picture in our hybrid flooring cost guide.
If you’re not sure whether your tiles are a good candidate, send us a few photos and a couple of measurements at a Sydney or Brisbane showroom — we’ll tell you straight whether it’s a lay-over job, a self-level-then-lay job, or a pull-up first.
