Installing LVP over tile in Florida

Most tile floors can take a rigid plank straight on top. The checks that decide it, the grout-joint rule, and the height math at every door.

The short answer

Yes, in most Florida homes. Rigid-core LVP goes straight over ceramic or porcelain tile when three things are true: every tile is solid, the surface is flat within 3/16 of an inch over 10 feet, and the grout joints are narrower than about 1/4 inch and shallow. Fill anything wider or deeper with a cement patch, use a 6.5 mm or thicker plank, and plan for the floor to rise by the plank's thickness at every door.

Checkpoint	Pass	If it fails
Tiles solid	No hollow sound when tapped, none loose or rocking	Re-set or remove loose tiles and patch the void level
Flatness	Within 3/16 in over a 10 ft straightedge, no lippage you can feel	Grind high edges, skim low areas with a cement leveler
Grout joints	Under about 1/4 in wide and less than 1/8 in deep	Skim the joints with a cement patch and let it cure
Cracks	Hairline in grout only	A crack running through tiles is slab movement: fix the cause first
Height at doors	Room to undercut casings and re-hang doors	Choose a thinner plank or remove the tile
Appliances	Dishwasher and range can come out and go back	Floor to the front of a trapped dishwasher and it is trapped for good

When can you not go over tile?

When the tile is the problem rather than the surface. A cracked tile line that runs across a room usually means the slab moved, and a floating floor will move with it. Loose or hollow tiles will drum under a plank and eventually break the click joint above them. And a bathroom tile floor that slopes to a drain or steps up to a curb will not take a rigid plank that needs to lie flat. In each of those cases removal, or a leveling pour, comes before the new floor.

The other hard stop is height. Tile plus thinset already sits around half an inch above the slab; add a plank and the finished floor in that room can be close to an inch above the hallway carpet or the garage step. Measure at every door and appliance before ordering.

Which grout lines need filling?

The rule on most rigid-core installation sheets is that the plank must be fully supported: joints wider than about 1/4 inch or deeper than about 1/8 inch get skimmed with a cement-based patch until they are flush. Modern rectified porcelain with 1/16 inch joints usually passes as it is. Older 4-inch ceramic with wide, recessed sanded grout almost never does, and the pattern will telegraph through a thin plank as a faint grid within a year. A 6.5 mm or thicker plank with an attached pad bridges small joints that a 5 mm plank shows.

How much does the floor rise? The transition math

A typical porcelain tile on thinset stands about 1/2 inch above the slab. Add the plank and you have the new finished height; subtract the height of the adjoining floor and you have the step a transition has to manage. The table assumes 1/2 inch of tile and thinset and a 3/8 inch adjoining floor such as carpet on a thin pad or the same plank laid on bare slab next door.

Plank	Plank thickness	Finished height over slab	Step to a 3/8 in floor
5 mm plank	0.20 in	0.70 in	0.32 in
5.5 mm plank	0.22 in	0.72 in	0.34 in
6 mm plank	0.24 in	0.74 in	0.36 in
6.5 mm plank	0.26 in	0.76 in	0.38 in
7 mm plank	0.28 in	0.78 in	0.40 in
8 mm plank	0.31 in	0.81 in	0.44 in

A reducer strip handles a step of up to about 1/4 inch cleanly; beyond that the transition becomes a visible ramp and it is worth asking whether the tile should come up. Doors get undercut by the plank thickness, and a dishwasher needs its full height under the counter after the floor goes in, which is why the floor runs under it, not up to it.

Do you need underlayment over tile?

No. All 77 of our floors have an IXPE pad attached, and a second pad under a click-lock plank voids most rigid-core warranties because the joints flex. Over tile the pad also takes up the last of the grout-line texture. What you may need is a cement skim in the joints, and on a slab that tested damp, a moisture treatment; see the humidity guide for what to test.

Which of our planks bridge tile best?

The thicker tiers. 6.5 mm and up gives the pad and core enough body to span small joints, and the 8 mm collections are the ones we would put over an older ceramic floor with wider grout.

Thickness	Collections	Per sq ft
6.5 mm	EIR 6.5mm, SSR 6.5mm, Ultra Clean SPC	$2.09
7 mm	APRES	$2.19
8 mm	IRIS 8, WHISPER WOODS, XD8 Series	$2.49

Common questions

Can I install LVP over tile in a bathroom?

Over a flat bathroom floor, yes; the plank is waterproof. Not over a floor that slopes to a drain or steps up into a curbless shower, and the toilet flange usually needs an extender for the new height.

Do I need to rough up or prime the tile first?

Not for a floating click-lock floor; nothing bonds to the tile. Cleaning and flattening are what matter. A glue-down install is different and needs the adhesive maker's surface prep.

Will the grout lines show through?

Not if the joints are under about 1/4 inch wide, shallow, and the plank is 6.5 mm or thicker with its pad. Wide recessed joints will show through a thin plank unless they are skimmed flush first.

Can I go over tile that has a few cracked pieces?

If the cracks are isolated and the tiles are still solid, patch and go. If a crack runs in a line across several tiles, the slab has moved and the floor above will follow it.
