Three big names dominate the Malaysian water tank market: King Kong, Weida and Kossan. All three are established local brands with their own product ranges. So what is the difference, and which one should you actually pick?
Full disclosure upfront: Abang Tank installs King Kong tanks as our main package — we explain why below, but we have made this comparison as fair as we possibly can.
King Kong Water Tank: The Stainless Steel Benchmark
King Kong is known first and foremost for stainless steel water tanks — their SUS range is among the most widely installed in Malaysian homes, with SPAN certification and sizes running from hundreds to thousands of litres. The brand’s core strengths: consistent weld quality and nationwide product availability.
That is why it is our main package choice: the King Kong Water Tank 1000L stainless steel, fully installed at RM 2,914 with a 6-month installation warranty.
Beyond the stainless steel range, King Kong also makes its own poly tanks — but on the ground, the King Kong name is almost always associated with stainless steel. For homeowners who want to "install and forget", the combination of a long-lasting material with a brand whose spare parts are easy to find is the safest formula there is.
Weida Water Tank: The Poly Pioneer
Weida is the name most synonymous with poly tanks in Malaysia — their polyethylene range is extensive, from household tanks to industrial tanks and rural water systems. If you are looking for a quality poly water tank backed by a long brand track record, Weida is among the safest bets.
Its weakness is not the brand but the material — every poly tank shares the long-term UV durability issue we cover in our stainless vs poly comparison. No brand name changes what polyethylene does under years of direct Malaysian sun.
From an installation standpoint, Weida tanks are light and easy to handle — replacement jobs are usually quick. Just make sure the base and stand are in good condition, because a poly tank depends entirely on flat, even support underneath to stop the tank body from warping once it is full.
Kossan Water Tank: The Established Alternative
Kossan — better known at the corporate level as a rubber manufacturer — also carries a range of poly water tanks and piping products. Its products are price-competitive and available at selected hardware shops.
For household use, the choice between Kossan and Weida usually comes down to the current price and the size availability in your area. Both are credible options with proper manufacturing behind them.
If you find a Kossan offer at an attractive price, check two things: the SPAN certificate for that specific model, and the wall thickness for the size you are choosing. Both are printed on the product specification — and both matter far more than the name on the tank sticker.
Water Tank Price by Brand: How to Compare Properly
The most common mistake when comparing brands: looking at the tank price alone. The shop price does not include delivery, installation labour, new pipe fittings and old tank disposal — all of that comes later and completely changes the maths. Two brands that look a few hundred ringgit apart at the shop can end up nearly identical once the full cost is counted.
The right way to compare: ask for the fully installed price, not the tank price. As an example of a transparent structure — our package: King Kong Water Tank 1000L stainless steel, fully installed at RM 2,914, everything included. Want to use another brand’s tank that you bought yourself? Installation labour is RM 1,350. Full numbers upfront, no surprise add-ons at the end of the job.
One more thing: make sure the tank being offered carries SPAN certification. An uncertified tank might be slightly cheaper, but you have no guarantee its material and thickness meet Malaysia’s drinking water standards.
Water Tank Size: Matching the Brand to What Your Home Needs
Every brand comes with its own range of sizes, but for typical terrace and semi-D homes in Malaysia, a 1000 litre water tank is the most practical starting point — enough for an average family without overloading the structure or the base.
Something people rarely check: the footprint and height of the tank differ between brands even at the same capacity. If you are replacing a tank on an existing stand, measure first — a water tank stand built for the old tank may not match the new brand’s dimensions, and that needs to be sorted before installation day, not during it.
Big family or a house with many bathrooms? Consider going one size up — the price difference between adjacent sizes is usually small compared to the cost of upgrading later, because the installation labour has to be paid all over again every time the tank is changed.
Conclusion: Which Water Tank Brand for Your House?
Want stainless steel — King Kong is the easiest choice to defend on quality and availability. Want poly for budget reasons — Weida and Kossan are both trustworthy brands; compare current prices for the size you need.
Whichever brand you pick, the installation determines half the final result — even the best tank gives problems if the base is tilted and the piping is sloppy. We install your tank (any brand) for RM 1,350 labour, or take our fully installed King Kong package.
One last tip: whatever the brand, ask what is included in the price — delivery, fittings, old tank disposal, warranty. A clear written answer is the mark of a contractor you can rely on, every bit as important as the brand of the tank itself.
FAQ — king kong water tank
Where is the King Kong water tank made?
King Kong is a local Malaysian brand with domestic manufacturing — one reason product availability and after-sales support are easier.
Can Abang Tank install brands other than King Kong?
Yes — our installation-only service (RM 1,350) applies to your own tank, any brand, poly or stainless steel.
Which brand is the cheapest?
For poly, Weida and Kossan vary by size and current promotions. For stainless steel, compare fully installed packages — the tank price alone does not reflect the full cost.
Does a water tank need SPAN certification?
Yes — SPAN certification means the tank meets the material standards for drinking water in Malaysia. Established brands like King Kong, Weida and Kossan carry certified products; be wary of unbranded tanks that are much cheaper.
