Moving a Toilet, Sink or Shower Position
What the Plumbing Involves (2026)

What is fixed and what can move

Every fixture has two connections: a water supply, which is a small pressurised pipe that can run almost anywhere, and a waste, which has to fall all the way to the drain. The waste decides how easily a fixture can move. ClickBina's small bathroom layout guide puts it simply: the toilet is tied to its soil pipe, so in most renovations it stays where it is, while the basin is easier to move because its drain is small.

So before drawing a new layout, find out where the existing soil stack, floor trap and waste outlets are. A layout that keeps the toilet over its existing outlet and moves only the basin and shower is usually far cheaper and lower-risk than one that moves everything.

How hard each move is

Short moves along the same wall are the easiest. Moving a fixture across the room, or to a different room, adds pipe length, fall and slab work.

Moving a toilet

ClickBina's squat-to-sitting conversion guide quotes the bathroom cost guide directly: the toilet drain is cast into the slab at a fixed position, and relocating it requires core-drilling and is expensive, typically RM2,000 – RM5,000 extra. The first question is always whether the new toilet can sit over the existing outlet.

• Slightly off: an offset connector or a toilet with a different outlet arrangement can bridge a small gap; the installer should confirm the fit before anything is bought.
• In the wrong place altogether: the drain is moved by core-drilling the slab. In a condo that slab is someone else's ceiling.
• A new position far from the stack: the soil pipe needs enough fall all the way, which may mean raising the floor or boxing in a pipe run.

Buy the new toilet after the old one is out and the outlet has been measured, not before. Our toilet bowl types guide explains the outlet options.

Moving a basin or kitchen sink

Basin and sink wastes are small, which makes them the most flexible fixtures to move. The waste can often run inside the wall, along the floor within the screed, or inside a vanity or cabinet to reach the existing outlet. The limits are fall and length: a long waste with too little fall drains slowly and blocks, and a kitchen sink carries grease, so a long run is worth avoiding.

Supply pipes are easier still, but every new joint hidden in a wall is a future leak point. Keep joints to a minimum and put them where they can be reached.

Moving a shower

A shower drains through a floor trap, and the whole wet floor is built to fall towards it. Moving the shower therefore usually means moving or adding a floor trap, re-screeding the falls to the new position, and re-waterproofing the whole wet area rather than patching around the old trap. Removing a shower kerb for a walk-in shower raises the same questions; see our walk-in shower guide.

Condos and strata: approval first

In a condo, the slab under your bathroom is the ceiling of the unit below. ClickBina's strata renovation rules guide lists relocating wet areas (bathroom, kitchen) without a structural engineer's assessment and management approval among the things you cannot do, because of the risk to the unit below. Core-drilling a slab, moving a soil connection or shifting a floor trap all fall into that category.

Put the proposed layout in writing to the management before booking the work, and keep the approval. On a landed house the slab question is simpler, but the soil pipe fall and the drain connections outside still apply.

Rough-in (first fix): pipes before walls close

Rough-in, or first fix, is the stage when the pipes go in and the walls and floor are still open. ClickBina's bathroom order-of-works guide describes it: the plumber sets the new water supply lines, the positions for the mixer, shower, basin and toilet, and the waste connections. This is when the heights of the shower mixer and basin must be decided, because they are fixed once the wall is tiled.

The same guide makes the most important point: new pipe runs should be pressure-checked before they disappear behind render or into the floor. A leaking joint found at rough-in costs minutes; found after tiling, it costs a wall. When fixtures move, there are more new joints, so this check matters more.

Second fix: fittings after the tiles

Second fix is the fitting out: sanitaryware, the shower set, the basin and vanity, the water heater and the glass screen go in last, once the dusty trades are finished. Each one is connected, run and checked for leaks at the joints. If the rough-in was right, second fix is quick. If a mixer was set at the wrong depth or a waste in the wrong place, second fix is where it shows, and the fix means breaking new tiles.

Waterproofing is part of every move

Any move that breaks the floor breaks the waterproofing with it. The squat-to-sitting guide is direct: treat the area, and ideally the whole wet floor, as a waterproofing job, with membrane, curing time and a flood test before the tiles go down. Our bathroom waterproofing cost guide explains the options.

What a relocation adds

These are ClickBina's published ranges (indicative 2026, Klang Valley). Moving a basin or sink is usually priced within the bathroom or kitchen work, so it has no separate line.

The cheapest layout change is the one that keeps the toilet and floor trap where they are and moves only what has a small waste.
