Bathroom Renovation in Kota Bharu

It can work on sound, well-bonded wall tiles and saves strip-out cost, but it fails on floors with movement, adds thickness that fouls doors and fittings, and hides the condition of the substrate and membrane. Most renovators strip back in wet areas — if a contractor proposes tile-over-tile in the shower zone specifically, treat it as a cost-cutting red flag.

Make every quote in Kota Bharu state: strip-out and disposal, first-fix plumbing and electrical, waterproofing (product named), tiling with a per-square-metre rate and tile allowance, fittings supply (brands listed or marked as owner-supplied), and second-fix. The cheapest quote is usually the one missing a line — often waterproofing or disposal.

Around 10-20% is normal, sometimes more where custom vanities or imported fittings must be ordered up front — in that case pay the supplier invoice share, not a round 50%. Hold 5-10% back until the room has been used for a week or two and the snag list (grout gaps, silicone, door alignment) is closed.

Strip-out, then first-fix plumbing and electrics (pipes and cables in walls), then substrate preparation and waterproofing, then tiling, then second-fix (toilet, vanity, taps, shower screen, lights), then silicone and snagging. If a quote or schedule doesn't follow this order, question it — out-of-sequence work is how leaks and redone tiles happen.

Not the one being renovated — water is disconnected and the floor is out of service for most of the project. If it is your only bathroom, ask the contractor to sequence works so the toilet is usable overnight where possible, and plan for gym showers or neighbours for the tiling and waterproofing week.

Walk-in showers cost less to build than bath-plus-screen setups, use less space, and suit ageing-in-place. Keep at least one bathtub in the home if you may sell to families — in most markets a home with no bath at all narrows the buyer pool. If you have two bathrooms, the common answer is one of each.

2025-26 guides put basic upgrades at RM5,000-RM15,000 and mid-range remodels roughly RM15,000-RM40,000, with premium projects reaching RM55,000-RM90,000. Tiling runs RM10-30 per sq ft plus RM5-15 per sq ft for waterproofing.

Yes — the JMB or management corporation must approve the works, typically with a refundable renovation deposit, contractor registration at the guardhouse, and restricted working hours. Landed-home internal refits need no council permit unless walls or drainage change.
