Choosing a wood species is the decision that shapes everything else about your flooring, its colour, how it wears, how it handles Malaysia’s humidity, and what it costs. Merbau, White Oak, and Walnut are three of the most requested species for solid timber flooring in Malaysian homes, and each brings a different balance of durability, appearance, and price.
This guide compares them directly so you can match the right species to your space.
Merbau Flooring
Merbau is a tropical hardwood with a density ranging from roughly 515 to 1040 kg/m³ depending on grade and cut, and it carries high natural resistance to fungus and pests. Its colour runs from brown to dark reddish-brown, and it’s already naturally suited to Southeast Asian humidity, which makes it a low-maintenance option for Malaysian homes.
Best for: homeowners who want strong natural durability and warm, deep tones without needing engineered climate control to keep the floor stable.
White Oak Flooring
American White Oak is a hardwood with a density of roughly 600 to 900 kg/m³, prized for its attractive grain ranging from light brown to dark brown. It has medium natural fungus and pest resistance, which is lower than Merbau’s, so proper kiln-drying and finishing matter more for White Oak to perform well long-term in humid conditions.
Best for: homeowners who want a lighter, more contemporary look and are willing to prioritise proper drying and finishing to get the best performance from the species.
Walnut Flooring
Walnut, as sourced from Burmese Walnut, has a density of roughly 800 to 900 kg/m³ with high natural fungus and pest resistance. Its colour ranges from light brown to darker brown with distinctive, attractive grain patterns. A Rustic Walnut grade is also available, with a red-brown to claret-red tone and streaks of lighter colour running through it, for a more characterful, less uniform look.
Best for: homeowners who want rich, dramatic grain and colour variation with durability that holds up well in Malaysian conditions.
Merbau vs White Oak vs Walnut: Side-by-Side
Factor | Merbau | White Oak | Walnut |
|---|---|---|---|
Density | ~515-1040 kg/m³ | ~600-900 kg/m³ | ~800-900 kg/m³ |
Fungus/pest resistance | High | Medium | High |
Colour | Brown to dark reddish-brown | Light brown to dark brown | Light brown to darker brown (Rustic: red-brown to claret-red) |
Grain character | Moderate, consistent | Attractive, pronounced grain | Attractive, distinctive grain |
Humidity suitability | Naturally well suited | Good with proper kiln-drying | Naturally well suited |
Typical look | Warm, traditional | Light, contemporary | Rich, characterful |
How to Choose Between Them
If durability with minimal fuss is the priority, Merbau or Walnut are the more forgiving choices, since both carry high natural resistance to fungus and pests straight out of the species profile. If you want a lighter, more contemporary interior palette, White Oak delivers that look, but it’s worth confirming with your supplier that the boards have gone through a proper air-drying and kiln-drying process, since White Oak’s medium resistance rating means the drying process matters more to its long-term performance than it does for Merbau or Walnut.
For a floor with strong grain character and colour variation from plank to plank, Walnut, particularly the Rustic grade, offers the most visual movement. For a more consistent, uniform tone across the room, Merbau or standard-grade Walnut tend to read as more even.
How Asia Timber House Prepares Every Species
Regardless of species, every ATH flooring plank goes through the same quality process: air-drying for 30-90 days followed by kiln-drying for 30-60 days, bringing moisture content down to 12-14%. This is what actually determines how stable and durable any species performs once installed, minimizing warping, shrinking, and fungal decay over the life of the floor.
Frequently Asked Questions
Which is more durable, Merbau or White Oak?
Merbau has higher natural fungus and pest resistance than White Oak, rated High compared to Medium, making it a more forgiving choice in humid conditions if drying and finishing aren’t closely controlled.
Is Walnut flooring suitable for Malaysia's climate?
Yes. Burmese Walnut has high natural resistance to fungus and pests, and when properly kiln-dried it performs well in Malaysia’s humidity, similar to Merbau.
What's the difference between Walnut and Rustic Walnut flooring?
Standard Walnut has a more uniform light-to-dark brown tone with attractive grain, while Rustic Walnut has a red-brown to claret-red colour with visible streaks of lighter colour, giving it a more varied, characterful appearance.
Does White Oak flooring need special care in humid climates?
White Oak has medium natural fungus and pest resistance compared to species like Merbau and Walnut, so proper kiln-drying to a stable moisture content and quality finishing are more important for its long-term performance in Malaysia’s humidity.
