Vinyl flooring Singapore price: thickness, subfloor and where it actually fails

A vinyl flooring Singapore price quoted as one per-square-foot figure hides the two variables that actually decide how the floor behaves: the wear layer on top, and the condition of the slab underneath. Plank thickness in millimetres is the number showrooms lead with, and it is the least predictive of the three. Vinyl is also the least regulated floor finish in an HDB flat, which cuts both ways — it goes down fast, and nothing external forces anyone to prepare the subfloor first.

Does laying vinyl need an HDB permit?

HDB answers this in a table rather than a paragraph. The Renovation Guidelines for Building Works list each type of building work against whether a permit is required, and vinyl sits in the first row:

"Laying of vinyl finishes/ carpet/ linoleum — Permit Required? No — Not applicable"

— HDB, Renovation Guidelines for Building Works

Permit-free is not the same as unregulated. Under the Housing and Development (Renovation Control) Rules, a flat owner must engage a contractor listed in HDB's Directory of Renovation Contractors, and engaging an unlisted one is an offence carrying a fine of up to S$5,000 — a rule that applies to a vinyl job exactly as it applies to a full hack-and-retile.

Two further conditions bite when planks go over an existing tiled floor rather than onto a bare slab. HDB's building works guidelines state that where floor finishes are laid over existing floor finishes using adhesive only, "there should be only 1 layer of existing floor finishes including cement screed before proceeding to lay the additional layer of floor finishes", and the "thickness of the floor finishes inclusive of the adhesive must not exceed 13mm" — a glue-down plank plus adhesive clears the 13mm limit HDB sets comfortably, but a plank sitting on a newly poured levelling screed may not.

Wear layer, core and total thickness are three different numbers

Total plank thickness governs how the floor feels underfoot and how much minor unevenness it can bridge, not how long the surface lasts. A rigid board and a thinner one scratch at the same rate if their wear layers are identical.

The wear layer is the clear film above the printed film, and it is the only part of the plank that meets a shoe, a chair castor or grit tracked in from the corridor. Suppliers quote it in mil or in millimetres, where one mil converts to 0.0254mm, so a 12 mil layer is about 0.3mm and a 20 mil layer about 0.5mm. Ask for the figure in millimetres on the manufacturer's technical data sheet rather than the sales brochure, and ask what residential warranty period the manufacturer attaches to that wear layer.

Core construction is the third number, and it determines dimensional behaviour. Stone-plastic composite (SPC) boards are rigid and move least with temperature, which matters in a unit with unshaded west-facing glass. Wood-plastic composite (WPC) boards are thicker and warmer underfoot but softer under point loads. Glue-down luxury vinyl tile (LVT) is the thinnest and most stable of the three, and also the least forgiving — it telegraphs every defect in the substrate because there is no rigid core to bridge them.

Attached foam underlay adds millimetres to the box measurement without adding durability. A plank with bonded foam and a plank of the same overall depth without it read the same on the box, but the second has more structural core in it.

Subfloor flatness and moisture decide the outcome

Flatness is checked with a long straightedge laid across the floor in several directions, with high spots ground down and hollows filled with a cementitious levelling compound. Skipping that step is the most common cause of a floor that clicks, dips or opens at the joints within a year, because a floating floor bridging a hollow flexes at every step and works the locking profile loose.

Grout lines are the specific trap when laying over existing tiles. An open grout joint under a thin glue-down plank eventually reads through the surface as a visible grid, so the tiled surface has to be skim-levelled first — which then has to be counted against the 13mm limit HDB sets for finishes laid over existing finishes with adhesive.

Moisture is the failure nobody sees coming. A slab that has been rained on during construction, a planter box, a leaking concealed pipe or a poor bathroom threshold detail will all push vapour into the underside of the plank, and a floating floor traps it there. An in-situ relative humidity probe drilled into the slab is the reliable test; a plastic sheet taped down overnight is the crude one. Either is cheaper than lifting a bedroom.

Grinding and levelling are noisy operations, which puts them inside HDB's tighter renovation window rather than the general one:

"General renovations (e.g. plastering, laying of floor screed) — Allowed on: Monday – Saturday, 9am – 6pm — NOT allowed on: Sunday and Public Holidays. Noisy renovations (e.g. demolishing walls, removing wall/ floor finishes) — Allowed on: Monday – Friday, 9am – 5pm — NOT allowed on: Weekends, Public Holidays, and eve of major public holidays."

Where vinyl actually fails in a Singapore flat

Gapping at plank ends is the classic failure. Click-lock floors are floating assemblies that expand and contract as a single sheet, so the perimeter expansion gap specified by the manufacturer must be left open behind the skirting, never filled with silicone, grout or tile adhesive. Long unbroken runs — a corridor flowing into two bedrooms — need a transition profile at the doorways rather than one continuous field.

Peaking is the opposite symptom of the same expansion problem. A floating floor pinned at one point cannot expand outwards, so it lifts in the middle instead. Heavy built-in wardrobes and kitchen carpentry installed on top of a floating floor are the usual culprits, which is why carpentry sequence matters: the wardrobe base should sit on the subfloor with the planks butted to it, not the other way round.

Curling at glue-down edges points to the adhesive rather than the plank. Pressure-sensitive adhesive needs a defined open time before the plank is laid, then rolling to transfer the bond, and in a humid unclosed unit that open time stretches. Planks laid into wet adhesive slide, then lift at the corners a few weeks later.

Water is the failure that turns a repair into a replacement. A vinyl plank does not rot, but the adhesive releases and a floating floor wicks water sideways under the whole run, so a washing machine hose failure in a service yard can reach a bedroom before anyone notices a stain. Wet areas remain a tiling job: HDB requires a renovation permit to replace bathroom or toilet floor finishes, and in newly built flats only after the 3-year restriction period on removing those finishes has passed.

Indentation shows up last and is the hardest to argue about afterwards. Refrigerator feet, piano castors and thin bar-stool ferrules concentrate load on a few square centimetres, and the softer the core, the deeper the mark. Load-spreading cups are worth specifying before the furniture arrives.

What a vinyl flooring Singapore price should itemise

Two quotations for the same flat can differ substantially and both be honest, because one includes preparation and the other assumes the floor is already flat. A comparable quotation separates these lines:

• TO FILL: supply and lay of vinyl plank, per sq ft, stated separately for each wear layer option
• TO FILL: cementitious self-levelling compound, per sq ft, and the assumed average depth
• TO FILL: grinding or skim-levelling of existing tiled floor, per sq ft
• TO FILL: skirting supply and installation, per running foot, by profile
• TO FILL: trimming of door leaves and re-hanging, per door
• TO FILL: removal and disposal of existing floor finish and debris, if applicable

Chemical claims deserve scrutiny of the same kind. From 1 January 2026, NEA requires interior paints sold in Singapore to contain no formaldehyde, with in-can content below 0.01% by weight — but that regulation covers paint only, not flooring adhesives and not the composite boards behind carpentry. A supplier calling an adhesive "formaldehyde-free" is making a product claim, so ask for the safety data sheet.

Deposits deserve the same scrutiny as specifications. CASE recorded 787 renovation complaints in 2025, down 18.2% from 962 in 2024, while prepayment losses in the renovation industry fell 73.8% to S$190,667, according to CASE's February 2026 media release — an improvement, and renovation still ranks second among industries for prepayment losses.

When vinyl is the wrong answer, and when it is obviously the right one

Vinyl is the wrong answer in bathrooms, on open balconies exposed to sun and rain, and on any floor where the existing surface is already two layers deep or drumming hollow under a tap test. A floor laid over a failing substrate fails with it.

Vinyl is the right answer where the existing tiles are sound, the budget is finite and the horizon is medium-term rather than lifetime — a resale flat being made liveable, a rental unit, a room refresh without a full renovation. A mid-spec plank over a properly levelled sound floor outperforms a premium plank over an unprepared one. Noble Interior Design Pte.
