Solid timber and engineered wood look very similar once installed. They differ underneath, and that difference matters in Singapore's tropical climate. This article walks through the practical tradeoffs we explain to clients before they pick one.
We install both. The right choice depends on the substrate, the level of aircon use, the budget and how long the homeowner expects to live with the floor before the next refurbishment.
What each one actually is
Solid timber flooring is a plank or strip of one piece of wood from top to bottom — typically 14-21 mm thick. Common Singapore species: Burmese teak, merbau, kempas, oak. The whole plank moves when humidity changes.
Engineered wood flooring is a multi-layer plank. The top layer (the "wear layer") is real hardwood — usually 2 to 6 mm thick. Below that, layers of plywood, HDF or softwood are stacked with the grain running in alternating directions. The cross-grain construction restrains seasonal movement.
Both are real wood on the surface. Once installed and varnished, you cannot tell them apart by looking. The difference is in how they behave over years.
Dimensional stability — the headline difference
Singapore's outdoor air sits at 75-90% relative humidity year-round. Indoor air-conditioned rooms can drop to 50-60% RH for hours each day, then rebound when the aircon is off. Solid wood expands and contracts across that range; engineered wood barely moves.
- Solid timber: Expect 0.5-2 mm of seasonal gap or cup on wide planks (150 mm+). Acceptable on narrower strip parquet and on well-acclimatised installs. Not acceptable if the homeowner cannot tolerate visible gaps in the dry season.
- Engineered wood: Movement is typically a quarter of a solid plank of the same width. Wide engineered planks (190-220 mm) remain practical in Singapore where the equivalent solid plank would be a maintenance liability.
If the home is heavily air-conditioned (master bedroom and study aircon on 8+ hours daily), engineered wood is the safer call. If the home is mostly fan-cooled and humidity sits in the upper range, solid timber moves less because the seasonal swing is smaller.
Substrate compatibility
- Concrete screed (most condos and landed properties): Both work. Engineered wood is more forgiving of slight screed unevenness because it does not move as much. Solid timber requires a flatter screed and a more careful adhesive choice.
- Existing tile or parquet (overlay): Engineered wood is the typical choice because the lower profile (12-14 mm) and reduced movement suit a floating or thin-glue install over an existing surface.
- Wet areas adjacent to balconies or bathrooms: Neither is recommended in the wet zone itself. In the adjacent dry zone, engineered with a marine-grade plywood core handles occasional splash exposure better than solid.
Refinishing life
Solid timber can be sanded multiple times. The 14-21 mm thickness gives 4-7 mm of usable wear surface above the tongue-and-groove — enough for three or four full sandings over a lifetime.
Engineered wood can be sanded too, but only into the wear layer. A 2 mm wear layer gives one light sanding; a 4 mm wear layer gives two; a 6 mm wear layer gives three. After that, the plywood core would be exposed.
This matters less than people expect. In practice, most Singapore wood floors are screen-and-recoated (light abrasion + new coat) every 3-5 years and only fully sanded every 12-15 years. Even a 2 mm wear layer typically reaches one full sanding in its useful life.
Cost
At the time of writing, ballpark per square metre supplied-and-installed:
- Strip parquet (Burmese teak or oak, 14-18 mm, narrow widths): mid-range cost, well-known product, easy to source. Lowest-cost entry point to real wood among the options we install.
- Solid timber planks (oak, walnut, wider widths): higher cost, especially for premium grades. Wider boards command a premium.
- Engineered wood (entry-grade, 2-3 mm wear layer): comparable to mid-range solid parquet. Often the best value for wide planks.
- Engineered wood (4-6 mm wear layer, premium European mills): highest cost, equivalent to or above premium solid timber.
Installation labour is roughly comparable between solid and engineered. Sanding labour at the end of life is identical. The total ownership cost over 15-20 years is closer than the upfront cost suggests.
Acoustic and underfoot feel
- Solid timber is heavier and feels firmer underfoot. Sound from below is slightly more attenuated. Hollow spots, if any, are easier to fix by lifting and reseating boards.
- Engineered wood is lighter and slightly more flex underfoot. With an acoustic underlay, it can match or exceed solid in impact-noise performance — important in condos with strict floor-noise rules.
Suitability summary
| Scenario | Recommended |
|---|---|
| Heavy aircon use, wide planks (180 mm+), modern condo | Engineered wood |
| Landed property, fan-cooled, traditional parquet look | Solid timber (parquet) |
| Overlay on existing tile or parquet | Engineered wood |
| Long-term family home (20+ year horizon, multiple sand cycles expected) | Solid timber |
| Tight budget, want real wood, average-size rooms | Engineered wood (entry-grade) |
| Premium luxury feel, oak/walnut planks, condo install | Engineered wood (4 mm+ wear layer) |
What we recommend
In a typical Singapore condominium with regular aircon use, an engineered wood floor with a 3-4 mm wear layer is the sweet spot. It looks identical to solid wood once installed, behaves predictably across years, refinishes once or twice during the homeowner's tenure, and costs less than premium solid timber planks of the same visual width.
For traditional parquet in landed homes — Burmese teak strip, herringbone or chevron patterns — solid is still the right answer. The narrow board width handles seasonal movement well, the look is harder to match in engineered, and the depth supports multiple sand cycles over decades.
We walk through both options on site and quote like-for-like. The decision should be driven by use case, not by marketing. Project-specific recommendations and pricing are confirmed in writing per job.
