How much does a bathroom renovation cost in Malaysia?

Cost breakdown by item

Knowing what each component costs lets you make informed trade-offs — for example, spending more on waterproofing (which protects the floor below) and less on decorative accessories:

Tier comparison: what you actually get

The jump from basic to mid-range is significant. Here is what changes at each tier:

Small bathroom renovation cost

A small bathroom renovation (common in condos — typically 30–45 sq ft) usually costs RM6,000–RM12,000 for a basic refresh or RM12,000–RM18,000 for a full mid-range remodel. To make a small bathroom feel larger, experienced contractors recommend:

• Light-coloured, large-format tiles (60×60 or larger) — fewer grout lines make the space feel continuous.
• A clear (not frosted) glass shower screen instead of a shower curtain.
• A wall-hung vanity that lifts off the floor visually.
• Recessed shelves hacked into the wall instead of freestanding shelving.

Why waterproofing matters most

Waterproofing is only 10–15% of the bathroom budget but it is the single most important step in any bathroom renovation. A failed or missing membrane causes:

• Water seeping into the concrete slab, causing ceiling stains and damage to the unit below.
• Mould growing inside the wall cavity, which is expensive to remediate.
• Tile de-bonding and hollow-sounding tiles within 2–5 years.

Always confirm your contractor applies a proper liquid membrane waterproofing system (not just a skim coat) and includes a written warranty of at least 5 years on the waterproofing work. If a contractor quotes unusually low and the waterproofing line item is missing, that is why.

What affects your bathroom renovation cost the most?

• Tile choice and area. A 3×3 m bathroom may have 30–40 sq m of tiled surface (wall + floor + ceiling of shower). Switching from standard to large-format or imported tiles can add RM2,000–RM5,000.
• Moving the toilet or floor trap. The toilet drain is cast into the slab at a fixed position. Relocating it requires core-drilling and is expensive — typically RM2,000–RM5,000 extra. Work with the existing position where possible.
• Sanitaryware brand. A basic toilet costs RM300–RM600; a Toto or Kohler rimless model runs RM1,500–RM3,500. Budget brands are fine for rental units; mid-range brands for an owner-occupied bathroom you plan to keep for 10+ years.
• Water heater type. An instant water heater is RM300–RM600 installed; a storage heater runs RM800–RM2,000 depending on capacity.

Worked example: a typical condo bathroom

An illustrative mid-range budget for a small (~35 sq ft) condo bathroom in the Klang Valley — a planning guide, not a quote:

A basic version without the glass screen and with budget sanitaryware could come in around RM8,000–RM9,000. A premium renovation with large-format stone-look tiles, a rain shower and custom vanity would run RM22,000–RM28,000.

One bathroom or multiple at once?

Renovating multiple bathrooms in the same mobilisation is more cost-efficient — the contractor is already on-site and haulage is shared. If you have a master bathroom and a common bathroom, doing them together typically saves 10–20% versus two separate projects. If you must phase, prioritise the bathroom that shows the most wear or has existing waterproofing failure first.

How to save without cutting corners

• Keep existing plumbing positions. The single biggest cost saving in any bathroom job.
• Choose mid-range local tiles over imported — the look and finish are often comparable; the import premium is mostly branding.
• Never cut the waterproofing or labour quality. Saving RM500–RM800 on waterproofing can lead to a RM5,000–RM15,000 rectification job within 3 years.
• Renovate multiple bathrooms together to share mobilisation cost.
• Reuse the water heater if it is less than 5 years old and working well.

How to choose a bathroom renovation contractor

• Confirm waterproofing is included with a warranty — this is the step that protects the floor below.
• Get an itemised quote: tiling, waterproofing, sanitaryware, plumbing and labour separately.
• Ask to see completed local bathrooms and check tiling neatness at corners and edges.
• Check the floor gradient plan — water must run to the floor trap, not pond around it.
• Agree a milestone payment schedule, not full payment upfront.

Common bathroom renovation mistakes to avoid

• Cutting the waterproofing budget — the most expensive mistake you can make in a bathroom renovation.
• Poor floor gradient causing water to pond around the trap — this leads to lingering dampness and mould.
• Cheap silicone and grout that mould within 6–12 months; specify anti-fungal grout for wet areas.
• Moving the toilet or floor trap unnecessarily — it adds significant plumbing cost and slab penetration risk.
• Skipping the curing time for waterproofing — a membrane needs 24–48 hours to cure before tiling over it.

How long does a bathroom renovation take?

A full bathroom renovation typically takes 1–2 weeks per bathroom in the Klang Valley, including hacking, waterproofing cure time, tiling and fitting. The key phases are:

• Day 1–2: Hacking existing tiles and screed; debris removal.
• Day 2–3: Waterproofing membrane application and cure.
• Day 3–6: Floor and wall tiling; grout.
• Day 6–8: Sanitaryware and glass screen installation, plumbing connections.
• Day 8–10: Snag fixing, silicone sealing, cleaning, handover.

Doing several bathrooms concurrently is more efficient than one at a time.
