Thinking of laying luxury vinyl tile over your current floor? You might be able to—but only if you do it right.
"I put LVT straight over our old laminate, and it looked fine at first. But after a few weeks, the joints started lifting because the floor wasn’t level." — Tom G., Surrey homeowner
Introduction
Installing LVT (Luxury Vinyl Tile) over an existing floor sounds like a dream: less mess, no need to rip anything up, and you save time and money. But while it is possible, there are important checks you must make first.
In this guide, we’ll walk you through:
Which existing floors LVT can go over
What preparation is essential
When you absolutely shouldn’t skip removal
We’ll also look at expert advice from manufacturers like Karndean and Quick-Step, and provide real-life examples to help you make the right call for your space.
When Can You Install LVT Over an Existing Floor?
LVT is suitable over certain floor types, if:
The subfloor is clean, dry, and level
The existing floor is securely bonded and not damaged
You’re using click-lock (floating) LVT rather than gluedown
According to Karndean, LVT can be installed over tile, wood, concrete, or existing vinyl floors, with the right preparation.
Flooring Types You Can Install Over
1. Existing Vinyl or Linoleum
Must be smooth, well-adhered, and not cushioned
Loose, curling, or textured vinyl must be removed
2. Ceramic Tile or Stone
Tiles must be level, with no cracks
Grout lines should be filled to avoid telegraphing
Use a levelling compound if needed
3. Laminate or Engineered Wood
Must be flat, stable, and not water-damaged
Any floating floor should be firmly locked with no flex
Remove skirting boards for a clean edge
4. Hardwood (Solid Wood)
Acceptable if the boards are secure and level
Best with click LVT over an underlay
Avoid gluing directly onto wood
When You Shouldn’t Install LVT Over an Existing Floor
Avoid overlaying if:
The current floor is soft or cushioned (like foam-backed vinyl or carpet)
There's mould, mildew, or water damage underneath
The floor is unlevel beyond 3mm over 2m
It's loose, damaged, or flaking
Source: Flooring Superstore recommends full removal if the existing floor affects the stability or warranty of the LVT.
How to Prepare the Existing Floor Before Installing Click LVT
Even if the old floor is in good condition, prep is everything. Here's what to do:
Step-by-Step:
Clean thoroughly – Remove all dirt, grease, and debris
Level the surface – Use a self-levelling compound where needed
Repair damage – Fix cracks, holes, or loose areas
Fill grout lines – On tiled floors, use a feather finish
Check for moisture – Especially on concrete or under vinyl
Lay underlay if needed – For click systems, acoustic and thermal underlay can help

Click vs Glue-Down LVT Over Old Floors
Best for overlaying existing floors
Can handle minor imperfections if underlay is used
Easier for DIY projects
Glue-Down LVT
Requires perfectly flat, solid base
Not recommended over existing floating or flexible floors
Better for heavy-use areas like hallways or shops
Expert Tip: Use a primer and smoothing compound under glue-down LVT to ensure adhesion if you’re not removing the old surface.
Common Problems (and How to Avoid Them)
Problem 1: Telegraphing
Raised patterns (like grout lines or bumps) show through the LVT.
Solution: Fill joints, use a smoothing compound
Problem 2: Movement or Noise
LVT shifts or clicks when walked on
Solution: Ensure flatness and use proper underlay
Problem 3: Failed Warranty
Manufacturer won’t cover flooring laid on improper base
Solution: Follow their install guidelines to the letter

Real Homeowner Experiences
"We put LVT over old vinyl in our kitchen and it worked brilliantly. Used an underlay and a moisture barrier just to be safe." — Leanne B., Manchester
"I tried to shortcut by laying LVT over an uneven tile floor. It looked fine for a week, then started lifting. Ended up redoing the entire job." — Chris R., DIY forum contributor

FAQ: Installing LVT Over Existing Floors
Q: Can I install LVT over old laminate or engineered wood?A: Yes, if it's flat, dry, and in good condition.
Q: Can you lay LVT over ceramic tiles?A: Yes, but you'll need to fill grout lines and check the surface is level.
Q: Do I need underlay if installing over an old floor?A: Often yes, especially for click LVT. It adds stability and comfort.
Q: Will the height of the floor increase too much?A: Possibly. Measure door clearances and transitions carefully.
Q: Is it worth removing the old flooring anyway?A: In many cases, yes. Starting fresh can prevent hidden issues and ensure a longer-lasting install.
Conclusion
Yes, you can install LVT over many types of existing flooring—but only if the base is solid, clean, and level. Rushing or skipping prep can lead to problems like movement, visible seams, and warranty issues.
Always follow the manufacturer’s instructions, and if in doubt, ask a flooring specialist to check your setup before laying anything down. The extra effort up front will save you time, stress, and money later on.
