3-Room HDB Resale Renovation Cost in Singapore: What You'll Actually Pay (2026)
Prices checked October 2026 against the published price lists of 526 contractors listed on Homees, MOM's 2025 wage data and Qanvast's 2026 report. How we price →
A resale 3-room costs more than the same flat as a BTO — usually **S$35,000–S$55,000** — because you're paying to strip out the previous owner's flat before building yours. Hacking, rewiring and fresh waterproofing stack on top of the same works a BTO needs, adding the familiar **20–40% resale premium**.| Scope | Typical cost | What you get |
|---|---|---|
| Light refresh | S$25,000 – S$38,000 | Repaint, partial flooring, keep layout & wet works |
| Standard overhaul | S$55,000 – S$68,300 | Hacking, new kitchen + bath, full carpentry, rewire as needed |
| Full transformation | S$55,000 – S$70,000+ | Gut renovation, layout changes, premium finishes |
Where these come from: Essentials = published whole-home packages from contractors listed on Homees (Oct 2026); Standard = Qanvast's 2026 projection from its 2025 project medians; Premium = designer-led work above that band. Furniture, appliances and contingency are on top. How we price →
Quick answer: for a comfortable standard overhaul of a resale 3-room in 2026, budget S$55,000–S$68,300 plus 10–15% contingency and a separate furniture-and-appliances budget.
Why resale costs 20–40% more than a BTO
The resale premium is three works a BTO never needs:
- Hacking & haulage — stripping old finishes and disposal: S$2,000–S$6,000. See hacking & demolition.
- Rewiring — older wiring and an undersized DB box: S$1,800–S$5,000. See electrical works.
- Fresh waterproofing — once the bathroom is hacked, the membrane is redone: S$800–S$1,500. See waterproofing.
A 3-room is smaller, so these works are cheaper than in a 4- or 5-room — but the premium over a BTO is the same proportional 20–40%.
Where the money goes — room by room
| Space | Typical cost | Detail |
|---|---|---|
| Kitchen | S$11,000 – S$18,000 | Hacking + new cabinets, countertop, tiling |
| Bathroom(s) | S$6,000 – S$14,000 | Full hack, waterproof, re-tile, fittings |
| Bedrooms ×2 | S$7,000 – S$13,000 | Wardrobe-led |
| Living/dining | S$6,000 – S$10,000 | Flooring, feature wall, lighting |
| Aircon (System 2–3) | S$1,800 – S$3,500 | New multi-split |
| Hacking, rewire, waterproof | S$4,000 – S$10,000 | The resale-only works |
Carpentry plus the kitchen/bath wet works lead the bill; how much you hack is the swing factor.
What actually moves your price
- Flat age and condition — older flats need more stripping and rectification.
- Layout changes — opening up the kitchen adds hacking and making good.
- Extent of hacking — keep a serviceable bathroom or kitchen and save thousands.
- Carpentry run and material tier — built-ins by the foot; laminate vs quartz.
- ID vs contractor — an interior designer adds ~10–20%.
Cost by estate
Resale 3-rooms are concentrated in mature estates:
- Tampines, Bishan, Woodlands — older flats often need full strip-outs and rewiring. Browse pros in Tampines, Bishan and Woodlands.
- Jurong — bathroom waterproofing and kitchen cabinet replacement are most-quoted. See Jurong.
Sample budget — standard 3-room resale overhaul
- Kitchen (hack + rebuild) ≈ S$14,000
- Bathroom (hack, waterproof, re-tile, fittings) ≈ S$9,000
- 2 bedrooms (wardrobes, flooring) ≈ S$10,000
- Living/dining (flooring, feature wall, lighting) ≈ S$8,000
- Hacking, haulage, rewire, DB upgrade ≈ S$6,000
- Aircon System 2–3 ≈ S$2,500
- Painting + sundries ≈ S$2,500
- Subtotal ≈ S$52,000, plus 10–15% contingency (~S$6,000)
That lands most standard resale 3-room overhauls in the S$55,000–S$68,300 zone for works alone.
Renovation timeline

HDB rules — the resale difference
- No 3-year tile rule for you — it applies only to new flats, so a resale owner can hack and re-tile bathrooms (just redo waterproofing).
- Licensed trades — PUB-licensed plumber, Licensed Electrical Worker (LEW); HDB-licensed, CaseTrust-accredited contractor.
- Permits — contractor applies; wall removal needs HDB approval, structural walls a PE endorsement.
- Permitted hours — noisy work Mon–Sat 9am–6pm; none Sundays/PHs.
How to keep the bill sensible
- Keep what still works — refurbish a sound kitchen or bath rather than gutting it.
- Overlay flooring over a flat, solid base.
- Right-size the rewire — get an LEW to assess.
- Get 3 itemised quotes with hacking, haulage and waterproofing line-itemed.
- Keep 10–15% contingency.
