Tiling in Selangor

A full bathroom (floor plus walls) typically takes 3-5 days: prep and waterproofing first, then setting, then grouting after the adhesive cures. Add days if old tiles must come off or the substrate needs levelling. Rushing cure times is the classic cause of cracked grout later.

Yes — tiles and grout are not waterproof; the membrane behind them is. Most countries mandate or strongly standardize wet-area waterproofing, and it must cure before tiling. If a bathroom quote doesn't mention waterproofing, that is the question to ask before anything else.

Tilers price labour per square metre (or square foot), with tiles, adhesive, grout and prep on top. Small-format ceramic on a flat floor is the base rate; large-format porcelain, natural stone, mosaics, herringbone patterns and wall work all cost more per unit because they are slower and less forgiving.

Sometimes — if the old tiles are solidly bonded and the extra height works at doors and fittings, tiling over is legitimate and avoids messy removal. It fails when old tiles are drummy (hollow-sounding) or the wall can't take the weight. A good tiler taps and checks before promising either way.

Removal is priced per square metre and depends on what's underneath: tiles on board come off fast, tiles on thick sand-cement beds are slow, noisy demolition work. Budget for substrate repairs after removal — you rarely know the wall or floor condition until tiles are off.

Confirm five things: substrate prep (levelling, boards), waterproofing in wet areas, adhesive and grout type, cuts and trims (edge profiles), and silicone to finish. Tiles themselves are usually excluded, and removing old tiles is a separate line that can rival the laying cost.

Almost always substrate or installation, not the tile: movement in the floor, missing expansion joints, adhesive coverage too thin (spot-dabbing), or tiling over a drummy layer. Cracked single tiles from impact are replaceable if you kept spares — always keep a box.

Labour typically runs RM 5-12 per sq ft (roughly RM 55-130 per m²) for standard formats. A full bathroom hack-and-retile with waterproofing commonly lands RM 6,000-15,000 before tiles.
