Can You Lay LVT Directly Over Old Ceramic Tiles?
Short version: yes, you usually can. Longer version: "usually" is doing a lot of work in that sentence, and it's the part that gets skipped in most of what you'll find on Google. I get asked this in kitchens and bathrooms more than almost anything else - homeowners looking at a dated tiled floor and hoping they can avoid the mess of ripping it out. Sometimes you can. Sometimes the honest answer is that skipping removal will cost you more in the long run than it saves you now.
This guide covers what actually needs checking before LVT goes over your old tiles, the three ways I see it go wrong when that checking gets skipped, what British Standards actually require in plain English, and the one thing almost nobody mentions: what the extra height does to your doors.
- LVT can go over sound, flat, dry ceramic tile - but "flat" has a real technical meaning (SR1, roughly 3mm over a 2m straightedge per BS 8204-1), not just "looks OK."
- Grout lines telegraphing through the new LVT after a few months is the most commonly reported failure on UK flooring and DIY forums - it happens when grout is left unfilled and the underlay is expected to hide it.
- Click-lock LVT is more forgiving of minor tile texture; glue-down LVT is far less forgiving and usually needs a full skim coat first.
- Concrete or screed under the tile needs to test below 75% relative humidity (BS 8203) before LVT goes down - tile does not automatically mean dry.
- Skimming over sound tile typically runs £10-30/m² in prep costs; removing the tile, disposing of it and making good the subfloor typically runs £35-70/m², based on published 2026 UK trade pricing guides.
- Adding LVT (and any skim coat) on top of existing tile raises the floor height - often enough to catch doors that cleared the bare tile fine.
The Real Answer: Yes, But Never Straight On Top
Ceramic tile is actually a decent base for LVT in principle - it's rigid, it doesn't flex, and it won't rot or move the way old floorboards can. The problem was never the tile itself. It's grout lines, lippage between individual tiles, and whatever's happening underneath the tile that the tile itself is hiding from you.
LVT is thin - a few millimetres at most - which is most of what makes it look good and lie flat, and also exactly why it has no ability to disguise a flawed surface underneath it. Carpet has pile and underlay to absorb small imperfections. LVT doesn't. Whatever texture exists in the tile beneath it will, eventually, show up in the finished floor. That's not a defect in the product - it's physics, and it's why the prep matters more than the tile choice.
The Three Ways This Actually Goes Wrong
These aren't hypothetical warnings - they're the specific, recurring failure patterns homeowners and tradespeople report on UK forums like r/DIYUK, Screwfix Community and BuildHub when LVT goes over tile without proper prep.
1. Grout Lines Telegraphing Through the LVT
This is the complaint that comes up again and again: months after the LVT goes down, the old grout pattern becomes visible - or feelable underfoot - as faint lines or shallow dips in the new floor. It happens when the grout lines are left as they are and the underlay is relied on to "bridge" them. It doesn't. Foot traffic and furniture pressure gradually press the thin vinyl into every recess beneath it, and the grid pattern of your old tiling reappears in your new floor.
The fix is straightforward in principle: grout lines need filling or feathering with a patching compound (or a full skim coat, on floors with a lot of grout) so the surface reads as one continuous plane before the LVT ever goes down.
2. Lippage Causing Ridges, Rocking and Click-Joint Failure
Lippage is the height difference between adjacent tiles - a tile that sits fractionally proud of its neighbour. It's often invisible to the eye and barely noticeable underfoot on the tile itself, but once thin LVT goes over the top, every one of those small steps becomes a ridge you can feel, or in click-lock LVT, a point where the joint doesn't sit flat. Reported outcomes on trade forums range from visible ridging to click joints separating or cracking directly over the high spots. Tile that was "good enough" as tile isn't automatically good enough as a base for LVT.
3. Trapped Moisture Causing Mould or Adhesive Failure
LVT is waterproof from above, which is exactly why it's a poor idea over a damp base. Older ground-floor tiled rooms - bathrooms and kitchens especially - can sit on a concrete slab that was never fitted with an effective damp-proof membrane, or has one that's since failed. Lay LVT over that without testing it first, and any residual moisture gets sealed in rather than allowed to escape, which shows up later as mould smells, softened adhesive, or vinyl lifting at the edges.
What "Flat Enough" Actually Means: BS 8204 in Plain English
Most articles on this topic tell you the floor needs to be "flat" without saying what that means in practice. In the UK, subfloor flatness for resilient coverings like LVT is defined by BS 8204-1, which sets out three surface regularity (SR) classes, measured against a 2-metre straightedge:
- SR1 - no more than roughly 3mm of deviation under the straightedge. This is the class LVT is generally installed to.
- SR2 - no more than roughly 5mm of deviation. Acceptable for some floorcoverings, but tighter tolerance is usually specified for LVT.
- SR3 - no more than roughly 10mm of deviation. A utility-grade tolerance, not suitable for LVT.
Glue-down LVT is the least forgiving of the two fixing methods - because it bonds directly and fully to whatever's beneath it, installers commonly work to an even tighter tolerance than standard SR1, sometimes around 2mm over 2m, with a full smoothing compound applied first. Click-lock (rigid-core/SPC) LVT floats above the surface rather than bonding to it, so it tolerates a bit more minor texture - but it still needs grout lines wider than roughly 3-5mm filled, and it still needs the underlying tile to be sound and stable. Neither format is genuinely "lay it and forget the prep."
Read more on how I apply these same standards to timber and concrete subfloors in the LVT subfloor prep guide.
The Door Problem Nobody Warns You About
Here's the part that gets left out of almost every guide on this topic, including most of the ones written by other flooring companies: adding LVT on top of existing tile makes your floor higher, and that height has to go somewhere.
A click-lock LVT plank typically adds somewhere in the region of 4-8mm on its own. A glue-down installation that needs a skim coat first can add a similar few millimetres from the compound plus the plank itself. Neither sounds like much in isolation - until you're stood in a doorway that no longer closes, or a hallway threshold that's suddenly become a trip hazard because the tiled bathroom floor is now noticeably higher than the hallway carpet next to it.
This is exactly why door clearances and threshold heights get checked as part of a proper site survey, not discovered on fitting day. It's a five-minute check with a tape measure that can save you the cost of trimming a door or fitting a reducer bar you didn't budget for.
Skim Over It or Rip It Out? The Real 2026 Costs
For sound, dry tile with nothing more than visible grout lines, skimming over the top is almost always the cheaper and less disruptive route. Full removal only earns its extra cost and mess when the tiles are loose, badly uneven, or you suspect a damp problem underneath. Based on published 2026 UK trade pricing guides, here's roughly how the two options compare in prep cost alone - before LVT fitting itself is even priced:
| Prep Route | Typical 2026 UK Cost | Best For |
|---|---|---|
| Skim coat / self-levelling compound over existing tile | £10–30 / m² | Sound, dry, mostly-flat tile with visible grout lines |
| Full tile removal, disposal & making good | £35–70 / m² | Loose or hollow tiles, severe lippage, suspected damp |
Those figures are prep only - they sit on top of whatever the LVT fitting itself costs. My own LVT fitting starts from about £17/m², quoted properly once I've actually seen your floor rather than guessed at it over the phone.

I'll check flatness, tap-test for loose tiles, and moisture-test the subfloor during a free mobile showroom visit - so you get an honest answer before you commit to either route.
Already Bought Your LVT?
If you've already bought click-lock or glue-down LVT from Tapi, Carpetright, ScS or online and just need it fitted properly over your existing tile, I offer a dedicated labour-only fitting service across South London, Surrey, West Kent and Sussex. Subfloor prep - skimming, grout filling, moisture testing - is priced separately once I've actually assessed your tiled floor, so there are no surprises on fitting day. For the full picture on what LVT needs underneath it regardless of whether you're going over tile, floorboards or concrete, see the complete LVT flooring guide.
Frequently Asked Questions
Can I lay click LVT straight over ceramic tile with no prep at all?
Only if the tiles are firmly bonded, the grout lines are shallow, and the floor is flat to within about 3mm over a 2m straightedge (SR1, per BS 8204-1). That's a genuinely high bar for most tiled floors - most jobs still need grout lines filled or a skim coat before click LVT goes down.
Do I need to remove the grout lines before laying LVT over tile?
You don't need to remove the grout, but you do need to fill or feather it so it doesn't sit as a visible recess. Grout telegraphing - where the old grout pattern becomes visible or feelable through the new LVT after a few months - is the single most common complaint I see reported on UK flooring forums when this step gets skipped.
Is click-lock or glue-down LVT better over old tiles?
Click-lock (rigid-core/SPC) is more forgiving of minor tile texture and is usually the safer choice if you want to avoid a full skim. Glue-down LVT looks and feels better long-term, but it's far less forgiving - it typically needs the tile skimmed to a tighter tolerance first because any texture in the tile will show through the thinner, fully-bonded vinyl.
Will laying LVT over my old tiles make my doors stick?
It can. Adding LVT and any levelling compound on top of existing tile typically raises the floor by several millimetres, and in rooms that need a full skim coat that can approach a centimetre. Doors that were fine on the bare tile can start catching, and thresholds into hallways or other rooms can end up uneven. Check door clearances before you commit, not after the floor's down.
Is it cheaper to skim over the tile or rip it out first?
Skimming over sound, dry tile is usually the cheaper route - broadly £10-30/m² in prep costs against roughly £35-70/m² for removing the tile, disposing of it and making good the subfloor underneath, based on published 2026 UK trade pricing guides. Removal only earns its extra cost when the tiles are loose, badly uneven, or you suspect damp underneath.
How do I know if my tiled floor is too damp for LVT?
You can't tell by eye or touch - it needs a proper hygrometer reading of the concrete or screed beneath the tile. BS 8203 and most manufacturers set the threshold at 75% relative humidity; anything higher needs a damp-proof membrane before LVT goes anywhere near it. This is why I test moisture as part of every survey rather than assuming a tiled floor is automatically dry.
Conclusion
Laying LVT over old ceramic tile is a genuinely sensible shortcut when the tile earns it - sound, reasonably flat, and dry. It's a false economy when it doesn't, because grout telegraphing, lippage-driven joint failure and trapped moisture don't show up on day one; they show up months later, once you've already paid for the floor and the fitting. The honest version of "can you do this" is always "it depends what's actually under your feet right now" - which is exactly what a proper survey is for.
