Waterproof kitchen cabinets in Singapore are cabinets whose body won’t absorb water, swell or rot when the sink leaks, the floor gets mopped or the kitchen stays humid for weeks. In practice, that means a carcass made of aluminium or stainless steel instead of the traditional plywood, MDF or particleboard.
The word “waterproof” is used loosely in quotations, though. A cabinet can have a waterproof body and still fail at the hinges, the countertop joint or a laminate edge. This guide covers which parts of a cabinet actually handle water, where Singapore kitchens take the most damage, and what to check before you sign a quote.
T Se7en Alucraft designs, fabricates and installs aluminium kitchen cabinets from our Woodlands workshop, so the examples below come from kitchens we measure, build and fit ourselves.
Water damages a cabinet through its weakest part, not its strongest. Here is how each part holds up:
Part | Aluminium cabinet | Plywood / MDF cabinet | What to ask |
Carcass (body) | Doesn’t absorb water or swell | Absorbs water through cut edges and screw holes, then swells | What are the sides, base and back panel made of? |
Doors | Aluminium core; the finish sits on metal | Board core; edges lift once water gets in | What is the door core, not just the finish? |
Finish (laminate, PET-G) | Water-resistant surface; edge finishing matters | Same finishes, but the wet core fails first | How are the edges finished and bonded? |
Hinges and runners | Depends on the hardware, not the cabinet | Same as aluminium cabinet | Which brand? Stainless or coated steel? |
Sink and countertop joint | Sealant joint using marble gum or silicone; needs occasional checks | Same as aluminium cabinet | Who seals it, and with what? |
Plinth (kickboard) | Won’t rot from daily mopping | Often the first part to swell | What is the plinth made of? |
An honest description of an aluminium kitchen is this: the body and doors are waterproof, while the hardware and sealant joints are water-resistant and need occasional care. If a quote calls a whole kitchen “100% waterproof”, ask which parts that covers.
For hands-on checks you can do at a showroom, see how to check if a kitchen cabinet is really waterproof.
Humidity gets the blame, but when we dismantle old kitchens, the damage is usually concentrated in a few places:
Rotting can leads to maggots. Here’s what we most often find when removing old cabinets, especially those that are swollen.
A cabinet is only as waterproof as its weakest component, so every structural part is aluminium and fabricated in-house to your site measurements.
The finish decides how the kitchen looks. The aluminium underneath decides whether it survives water. The finishes we offer:
Brushed hairline gold: a metallic feature finish. It can be used on full doors, or accents, or trimming like the video you’ll see below:
If water resistance is your main concern, this is how the common cabinet materials compare. Lifespan depends heavily on workmanship and how close a cabinet sits to water, so we haven’t listed year counts we can’t back up.
Material | When it gets wet | Termites | Look | Main trade-off |
Aluminium | Doesn’t swell or rot | Not affected | Wide range of finishes, incl. woodgrain | Costs more than basic plywood; however, cost less than stainless steel. |
Marine plywood | Resists moisture better than standard plywood, but cut edges and screw holes still absorb water | Vulnerable unless treated | painting looks | Fails after a few years when coating wears off. Swells at edges is common. |
MDF / particleboard | Swells very quickly once water reaches the core | Vulnerable | Laminated board | Shortest life in wet zones |
Stainless steel | Doesn’t swell or rot | Not affected | Industrial | Shows fingerprints and scratches; heavier. Most stainless steel in the market are not “true” stainless steel. |

Aluminium solves water and termite problems, but it doesn’t suit every situation:
HDB kitchens are compact, and many resale flats come with a sink base that is already failing. Aluminium works for both: it is light and fabricated to your exact measurements, so awkward pipe positions and corners don’t force wasted space. In rare cases, countertop can be preserved, saving you lots of money in the process.
All works must follow HDB’s renovation rules on permitted hours and works when it comes to hacking works. However, when it comes to ONLY cabinet works, this does not apply. Check out our HDB kitchen renovation rules guide covers what applies. See also BTO kitchen cabinets and resale HDB kitchen renovation.
Condo kitchens are often open to the living area, so the cabinets double as furniture. Handle-less doors with push-to-open or integrated finger pulls keep the run clean. Check your condo management’s renovation rules on working hours, deposits and lift booking before scheduling installation. For budgeting, see condo kitchen renovation cost.
Landed homes often have a separate wet kitchen or an outdoor cooking area exposed to rain and splashing. That is where aluminium’s advantage over board materials is largest.
Example project: Greenleaf Avenue aluminium kitchen. (I removed 27 because it is too specific)
Example project: Onon Road Aluminium Kitchen where the cabinet is fully exposed to sun and rain.
Aluminium cabinets are priced mainly by cabinet length (top and bottom runs), then tall units, finish, accessories and installation scope. Tall pantry units and pull-out systems move the total the most.
In the market, a starting price is based on per foot run or typically range by flat types. As we are the direct factory in the market, cabinets are made directly by us calculated at the lowest costings. For example, most 4-room HDB kitchen we install fall between S$5,000 to S$20,000, depending on what scope of work and appliances are covered.

This is a takeover resale 4-room HDB home in Sembawang that wanted to retain their original concrete tiles but change out the broken and rotten wooden cabinets to aluminium ones. In this tiktok video, you can see the before and after. By tearing out the old frame, cleaning the maggots and any organic materials from wood, we were able to measure and custom make new aluminium frames and doors to ensure exact fitting. We were then able to give new life into the cabinet, making the cabinet useful to the owner without spending too much. Link:

The aluminium body and doors don’t absorb water, swell or rot. Hinges, runners and the sealant around the sink and countertop are water-resistant rather than waterproof. Though, it is already market proven and tested by us to confirm it is good enough for residential uses.
Yes. The sink base is where aluminium makes the biggest difference. However, you also need to remember that it is not just the sink base that gets exposed to the water, but the countertop where food preparation gets exposed to water the most. You can even consider adding ventilation cutouts and choose an open or sealed back panel based on your plumbing. See aluminium under sink cabinets.
Marine plywood handles moisture better than standard plywood, but its cut edges and screw holes can still absorb water when the sealing fails. In most cases, marine plywood fails very quickly within a few years of using and eventually still get swapped out. In the sink base and other wet zones, aluminium removes that risk.
Aluminium doesn’t rust the way steel does. Its surface can oxidise. This is the reason why we powder-coat it, where it fuses to the surface, making it extremely difficult for water to penetrate even after years of usage. More in can aluminium kitchen cabinets rust?
Yes. Because they’re fabricated to your measurements, narrow layouts and awkward pipe positions don’t force wasted space. See our planning tips for narrow HDB kitchens.
Wipe with a damp cloth and mild detergent. Avoid abrasive pads on laminate and PET-G surfaces. Full routine in our aluminium kitchen cabinet maintenance guide.
Warranty will highly depends on the material that clients have chosen, gadgets, laminates and so on. Till date, none of our clients have activated us for warranty claims. For what a good warranty should include, see our kitchen cabinet warranty guide.
