Defect check before renovating resale bathroom in Singapore
Renovating a resale HDB bathroom without checking for defects first can lock in problems that cost more later. This HDB Renovation Guide Singapore explains the defect inspection you should do before a bathroom renovation, with the HDB rules that apply and a practical checklist. The core point is to find hollow tiles, leaks, and seepage before you hack, because HDB approval is needed for any toilet renovation.
why inspect before you renovate
Resale flats have seen years of use, and bathrooms take the hardest hit. A defect caught after tiling is hidden forever and may worsen. HDB requires approval for any toilet renovation, and for BTO flats the toilet tiles come pre done under a 3 year defect liability period, hacking them early can void the waterproofing. Even in resale, knowing the real state guides what you can keep and what must go, saving money and time.
common defects to check
- Hollow tiles: tap the floor and walls, a dull sound means a loose bond that will crack.
- Water seepage: look for stains on the ceiling below and damp grout lines.
- Uneven flooring: a slope that pools water points to a failed screed.
- Faulty power points: test the heater and socket with a tester.
- Door alignment: a sticky bathroom door signals movement in the frame.
- Silicone failure: black mould at joints shows water has been sitting.
the HDB rules that apply
Any toilet renovation needs HDB approval, and only an HDB registered contractor may do regulated works through the Renovation Contractor Registration System. You cannot hack the original reinforced concrete floor screed in many flats, and the waterproofing layer must be protected. Window works in the bathroom follow the 2011 rule: all HDB windows must be done by HDB approved window contractors using shatter resistant glass and proper restraints. Rivets need regular checks by law.
a practical inspection checklist
Walk through this before signing the renovation quote:
- Do a tap test on every tile and mark the hollow ones.
- Run water for ten minutes and watch the ceiling below for drips.
- Check the floor slope with a level and a cup of water.
- Photograph every defect with a date for your contractor and HDB file.
- Confirm with HDB which walls are non structural and may be hacked.
- Agree in writing what the contractor will fix versus replace.
