Each decision below is shown three ways — what it changes in use, which way it moves the cost, and how it looks. Price direction only. The responsible supplier confirms the quotation after measurement and specification.

See what each option changes
Shared / nearest drain
In use
Washer, dishwasher and AC run to the nearest available drain — simplest, but shared runs can gurgle, back up or overflow.
Cost impact
Included — specialist quotation required
How it looks
Hoses to a visible standpipe.
Dedicated standpipes & drains
In use
Each appliance gets its own trapped standpipe or drain, sized and positioned before the cabinets — no back-flow and no gurgle.
Cost impact
Low — specialist quotation required
How it looks
Tidy, concealed standpipes behind the appliances.
Plus AC condensate to a safe outfall
In use
AC condensate is piped to a proper outfall — not dripping onto the floor or a neighbour — with a pump where gravity will not reach.
Cost impact
Moderate — specialist quotation required
How it looks
No drip stains and no visible condensate hose; it is routed and concealed.

Single floor trapIncluded
Graded falls to the trapEssentialLow$
Linear channel + secondary drainSignatureModerate$$
See what each option changes
Single floor trap
In use
One trap with a nominal fall — water can pond in the low spots of a Sarawak wet kitchen or bathroom if the screed is not set right.
Cost impact
Included — specialist quotation required
How it looks
One visible floor grating.
Graded falls to the trap
In use
The floor screed is graded to fall to the trap from every direction, so water always reaches the drain and nothing pools.
Cost impact
Low — specialist quotation required
How it looks
A level-looking floor that quietly drains; the fall is felt underfoot, not seen.
Linear channel + secondary drain
In use
A linear channel and a secondary or overflow drain move large volumes fast and give a back-up if the main trap blocks — best for heavy wet use and flood-prone homes.
Cost impact
Moderate — specialist quotation required
How it looks
A clean linear slot drain instead of a central grating.

Standard bottle trapsIncluded
Anti-odour deep-seal trapsEssentialLow$
Concealed / linear wasteSignatureModerate$$
See what each option changes
Standard bottle traps
In use
Basic traps work day to day, but a shallow water seal can dry out or get pushed through, letting drain smell back into a Sarawak wet kitchen.
Cost impact
Included — specialist quotation required
How it looks
Standard white traps under the sink.
Anti-odour deep-seal traps
In use
Deeper water seals and anti-odour traps hold against evaporation and back-pressure — no drain smell rising in the heat.
Cost impact
Low — specialist quotation required
How it looks
Unobtrusive; the benefit is the absence of smell, not a visible part.
Concealed / linear waste
In use
Concealed bottle-less wastes and linear channel drains — a little more to clean well, but the cleanest look and the fastest drainage.
Cost impact
Moderate — specialist quotation required
How it looks
A slim linear channel or a near-invisible waste; minimal and modern.
Each decision's badge shows who supplies it. A real figure belongs only to what ALUMAX supplies; appointed-trade works — electrical, air-conditioning, ceiling, flooring, painting, data and security — are quoted by the trade, and loose items are the owner's own purchase. ELS specifies and coordinates throughout. Cost is a relative direction only, never a price; maintenance is described in each option's “In use”.
