Illustrative concept design: grey large-tile bathroom with a sliding glass shower, a tall frosted window, a seated toilet and floor traps

An old house bathroom often has a built-in bathtub, a squat toilet, coloured tiles, galvanised pipes and waterproofing that has outlived its design life. In a landed house there is no unit below, so hacking the floor to rebuild the falls and the waterproofing is normal and usually the right call. The look is then a choice: keep the retro pink or mosaic tiles you like, or go fully modern with a walk-in shower, a seated WC, a wall-hung basin and a proper exhaust. These 12 concept designs show full refits, retro keeps and safety upgrades. Use the filters below to narrow them by style or home type.

How to plan an old house bathroom makeover

Start with what you cannot see. ClickBina's old house renovation guide explains that bathroom waterproofing in a 30 to 50-year-old house is past its design life, and that galvanised iron pipes more than about 25 years old should be replaced while the walls are open. In a landed house the bathroom has no unit below, so hacking the floor to rebuild the falls and the membrane is normal.

  • Strip and rebuild the floor and waterproofing if there are leaks, damp walls or poor falls.
  • Re-pipe to PPR before any new tiles go on.
  • Decide the look: keep coloured or mosaic tiles you like, or go fully modern.
  • Fix the air: a louvre window or an exhaust fan, so the new finish does not grow mould.
  • Plan for age: a seated WC, grab bars and an anti-slip floor if parents will use it.

For the rest of the house, the old house makeover gallery shows what to keep and what to replace in living rooms, floors and stairs.

Checks before you start

  • Leaks. Find out whether the old bathroom leaks before deciding to keep tiles; tiles over failed waterproofing will leak again.
  • Drain positions. Moving a toilet or floor trap means breaking the slab; keep them where they are if you can.
  • Wiring. Heaters, fans and lights in a bathroom need safe wiring by a competent electrician.
  • Skylights. A new opening in the roof needs proper flashing; see the skylight guide.

Common Questions

Should I remove the old bathtub?
If nobody uses it, most owners do. The floor under it is re-waterproofed and re-tiled with a fall to a drain; ClickBina's guide puts a full hack-and-redo including retiling at RM4,500 – RM9,000.
Can I keep my pink or green 1980s bathroom tiles?
Yes, if they are sound and the bathroom does not leak. Clean and re-grout them and pair them with simple white fittings.
Do I need to hack the floor of an old bathroom?
Often yes, when the waterproofing has failed or the floor does not drain. In a landed house there is no unit below, so rebuilding the falls and membrane is the lasting fix.
Should I change the pipes during a bathroom makeover?
If they are galvanised iron and more than about 25 years old, yes, while the walls are open.
How do I brighten a windowless back bathroom?
A small skylight brings daylight in; ClickBina's skylight guide puts a basic polycarbonate one at RM1,500 – RM4,000. Add an exhaust fan for air.
How do I make an old bathroom safe for elderly parents?
A seated WC, grab bars fixed into solid wall, anti-slip floor tiles and a level shower entry.
Are the designs on this page real ClickBina projects?
No. They are illustrative concept designs that show bathroom options. Your bathroom is assessed and quoted after a check.
