Browse 12 bathroom ideas for older flats and apartments, where one small combined bathroom serves the whole home and leaks reach the unit below.
📍 We serve KL, Selangor & Putrajaya.
Most older Malaysian flats and low-cost apartments have one small combined bathroom and toilet shared by the whole household, often with a squat toilet on a raised step, old mosaic tiles, a high window to the air well and the block's soil stack running through it. Leaks from it go straight to the unit below. The designs that suit it level the floor and fit a seated toilet, split the wet and dry areas with one glass panel, tile over sound old tiles, improve air with louvres and a fan, and add grab bars for elderly parents. These 12 concept designs show modern, minimalist, safe-and-practical and budget-refresh ideas.
Each design below is an illustrative concept render of a bathroom in an older flat or apartment, grouped by style. Tap any image to enlarge it, and open the details for what each idea suits, the finish and what to watch for. Every card links to the ClickBina guide that covers the work behind that look.

flat waterproofing →These are illustrative concept designs created to show bathroom options for flats and apartments. They are not completed ClickBina projects. We renovate flat bathrooms in KL and Selangor, and your bathroom is assessed and quoted to its own size, pipes, waterproofing and the management's rules.

Start with the floor. ClickBina's walk-up flat guide explains that flat bathrooms of this era often leak into the unit below, and there are two real routes: where the tiles are sound, non-hacking re-waterproofing; where the floor has failed, hack, lay a new membrane, ponding-test and retile. Decide that first, then the look.
Then choose the look: light tiles, one mirror and simple fittings make a small flat bathroom feel bigger.
| Move | What it solves | What to check |
|---|---|---|
| Non-hacking re-waterproofing | Leaks through a sound floor | Tiles firmly bonded |
| Full hack, membrane and retile | A failed floor and leaks below | Approval, hours, ponding test |
| Squat to seated WC | Easier for older users | Step removal; drain position |
| Glass panel | Keeps the dry side dry | Floor falls to the trap |
| Louvres and exhaust fan | Damp and smells | Fan vents outside |
| Grab bars and seat | Safety for elderly users | Solid wall fixings |
| Your bathroom | Usually works | Watch for |
|---|---|---|
| Squat toilet on a step | Level the floor and fit a seated WC | Drain position and waterproofing |
| Old mosaic, no leak | Large tiles over the mosaic | Bond of the old tiles |
| Leaks to the unit below | Full hack, membrane and retile | Approval and the neighbour's ceiling |
| Dark air-well bathroom | Glossy white tiles, long mirror, louvres and a fan | Ventilation |
| Elderly parents | Anti-slip floor, grab bars, a shower seat | Fixings into solid wall |
This gallery covers the bathroom in older flats. For leaks and shared repairs, see the apartment and flat waterproofing guide; for the toilet change, squat to sitting toilet conversion; and for layouts, small bathroom layouts.
The walk-up and low-cost flat renovation guide explains what to fix first across the whole flat, and grab bar installation covers fittings for elderly parents.
ClickBina's walk-up and low-cost flat guide puts a full hack, new membrane and retile at RM8,000 – RM14,000 per bathroom, and non-hacking re-waterproofing on sound floors at RM1,500 – RM3,500. The squat to sitting toilet guide puts full hack-and-redo waterproofing at RM4,500 – RM9,000, with RM2,000 – RM5,000 extra if the drain has to be moved, and the no-hack makeover guide puts a fixed glass shower panel at RM500 – RM900 (indicative Klang Valley ranges for 2026).
Grab bars, heaters, louvres and doors are quoted per job. Ask for the waterproofing to be priced separately from the tiles and fittings so you can see what protects the unit below.
