Yang selalu under-quote
- Waterproofing dinding shower — banyak quote cuma waterproof lantai. Dinding shower kena waterproof juga sampai 1.8m tinggi. Kalau tak — leak ke bilik sebelah atau atas siling unit bawah.
- Hacking depth. Kalau lantai bilik air anda diatas slab konkrit yang dah waterproof developer, hacking penuh boleh tembus waterproof asal. Kena re-do. Tambah RM 1,500–2,500.
- Pipa lama. Rumah > 25 tahun selalu kena tukar pipa galvanised ke PEX. Kalau quote anggap pakai pipa lama, dalam 2 tahun anda akan ada masalah leak.
- Floor gradient. Lantai bilik air kena slope ke floor trap. Kalau slope tak betul, air bertakung. Patut bayar RM 300–600 untuk slope correction kalau perlu.
- Ventilation. Tanpa exhaust fan, bilik air kondo akan jadi mouldy dalam 6 bulan. Tambah RM 350–600 untuk extractor fan + ducting.
Sanity check
Untuk bilik air 40–50 sqft di Klang Valley dengan standard scope (re-tile penuh, retain layout, sanitary ware mid-range), quote yang masuk akal jatuh dalam RM 9,000–14,000.
- Quote RM 5k untuk full bathroom = pasti ada corner cutting (waterproofing tipis, sanitary ware super-budget, no warranty).
- Quote RM 18k+ = sama ada premium finish (yang patut justify), atau contractor markup tinggi. Tanya line by line.

FAQ
Soalan lazim
01Berapa kos renovate satu bilik air?+
Bilik air standard 35–50 sqft di Klang Valley jatuh RM 8,000–18,000. Light refurb (cuma tukar tile, retain plumbing): RM 4,500–7,000. Full overhaul dengan re-route pipa: RM 15,000–28,000. Premium (rain shower, LED mirror, freestanding tub): RM 25,000+.
02Waterproofing patut bayar berapa?+
RM 8–14 per sqft untuk waterproofing 2-coat dengan PU atau cementitious. Bilik air 40 sqft = RM 320–560. Kalau quote tak include waterproofing, walk away. Failure waterproofing di apartment = liability ke unit bawah, sangat mahal.
03Tile mahal vs tile murah — perbezaan?+
Tile RM 6–12/sqft (Malaysia local) cukup untuk daily use. Tile RM 25–50/sqft (Italy/Spain import) lebih cantik, tahan stain lebih baik. Beza utama: warranty (local 1 thn, import 3–5 thn), pattern matching, dan PEI rating.
