Need a toilet, pantry or wash points in a new shop or office? Start with where the supply and drain really are.

A plumbing fit-out in a shop or office is decided by where the existing supply and the drain or stack are, not by where you would like the sink. Survey both before you sign, agree with the landlord who owns which pipe, keep new drains short with a proper fall and access points, pressure-check new supply runs before walls close, and flood-test wet floors before tiling. Moving a toilet drain adds RM2,000 – RM5,000 on ClickBina's guides. A site visit is RM150, waived if you go ahead.
Most new tenants need at least one of these: a staff toilet, a pantry sink, wash points for a salon or clinic, a hand-wash basin at a food counter, or a full commercial kitchen. The unit may be a bare shell with one capped pipe, or a previous tenant's layout that is in the wrong place for you.
The expensive part is rarely the tap. It is getting clean water to the new point and dirty water away from it with enough fall, without cutting through a slab you do not own.
ClickBina's drainage and sewer pipe guide notes that a drain camera inspection shows the condition of old pipes before anything is hacked, which is worth doing on an older shoplot.
Responsibility splits three ways, and the lease can move it again, so get it in writing before the works start.
| Part of the system | Who usually owns it | Source |
|---|---|---|
| Water meter and the supply up to it | The water operator (Air Selangor in the Klang Valley); SPAN is the national commission | Water meter and sub-meter guide |
| Private sewer pipes inside the property | The owner or occupier; Indah Water says customers may engage private contractors to clear a private blockage | Commercial plumbing maintenance guide |
| Public sewer beyond your connection | Indah Water Konsortium (IWK) operates the public sewerage system | Grease trap guide |
| Common stacks and pumps in a strata block | The JMB or MC; pipes inside your unit are usually yours | Commercial plumbing maintenance guide |
ClickBina's plumbing services guide makes the practical point: work on the incoming supply and metered connection, and anything that ties into the public sewer or the water authority's side, falls under licensed trades and utility rules. Confirm current requirements with the operator, IWK or the council for your premises.
ClickBina's water meter and sub-meter guide covers commercial subdivision: a shoplot or floor split into tenancies off one supply, where each tenant should carry its own consumption. The operator's meter itself is sealed equipment.
The drainage guide lists what makes any drain work: a steady fall towards the sewer, vents so traps are not siphoned dry, a water-holding trap at every fixture, and rodding eyes and inspection chambers at bends and junctions. In a renovation it asks for the material and fittings named in the quote, the fall checked before the floor is screeded, a water test of new drains before tiling, proper adaptors between old and new pipes, and management approval before touching a shared stack.
Every metre of new drain needs fall, which eats floor or ceiling height. A sink far from the stack may need a raised floor or a pump, so ask early.
A staff or customer toilet takes far more use than a home bathroom. Choose robust fittings, a floor trap in the right place and finishes that can be cleaned daily. ClickBina's office and commercial toilet guide covers cubicles, sensor taps, urinals and dryers. The toilet is the hardest fixture to move because it is tied to its soil pipe in the slab; ClickBina's guide to moving a toilet, sink or shower prices relocating the drain separately.
ClickBina's grease trap guide adds that retrofitting a trap into a finished kitchen almost always costs more and works worse than building it in.
| Stage | Plumbing task | Check before moving on |
|---|---|---|
| Layout | Mark every fixture position and height | Positions agree with the fittings chosen |
| Rough-in (first fix) | Lay supply and waste pipes, set outlets | Pressure-check the new supply runs |
| Screed and falls | Form the floor falls to the floor trap | Water runs to the trap |
| Waterproofing | Membrane over the wet floor and up the walls | Flood test before tiling |
| Second fix | Fit sanitaryware, taps, heater, appliances | Every joint run and checked for leaks |
This sequence follows ClickBina's guide to moving bathroom fixtures, which makes the key point: a leaking joint found at rough-in costs minutes; found after tiling, it costs a wall.
