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 3-room BTO is the most budget-friendly HDB to renovate — it's smaller, and as a new flat it's a blank slate with no hacking or rewiring. For 2026, a full renovation typically runs **S$11,000–S$52,500**, with a lean essentials-only job starting around **S$18,000** and a fully customised one reaching **S$55,000**.| Scope | Typical cost | What you get |
|---|---|---|
| Essentials | S$11,000 – S$18,000 | Flooring, basic carpentry, painting, lights — liveable |
| Standard | S$40,800 – S$52,500 | Full carpentry, kitchen + 1–2 baths, ceiling/lighting, aircon |
| Premium | S$52,500 – S$70,875+ | Designer finishes, extensive built-ins, smart home |
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: budget around S$40,800–S$52,500 for a comfortable mid-range 3-room BTO renovation in 2026, plus 10% contingency and a separate furniture-and-appliances budget of S$8,000–S$15,000.
Where the money goes — room by room
A 3-room is typically two bedrooms plus living/dining, kitchen and bathrooms — fewer rooms than a 4- or 5-room, which is why it costs less. Each space links to its full guide:
| Space | Typical cost | Detail |
|---|---|---|
| Kitchen | S$9,000 – S$15,000 | Usually the priciest room |
| Bathroom(s) | S$5,000 – S$12,000 | One or two depending on layout |
| Bedrooms ×2 | S$7,000 – S$13,000 | Wardrobe-led; ~S$3,500–S$6,500 each |
| Living/dining | S$5,000 – S$9,000 | Flooring, TV console, lighting |
| Aircon (System 2–3) | S$1,800 – S$3,500 | Smaller system |
| Whole-flat painting | S$900 – S$2,000 | Ceilings + common areas |
Carpentry is still the biggest driver even in a smaller flat — but there's simply less of it, which keeps the 3-room budget down.
Why a BTO is cheaper than a resale
A new 3-room BTO skips the costly works a resale needs — no hacking (guide), no rewiring (guide), no waterproofing replacement (guide). The same flat costs 20–40% more as a resale. (See the 3-room resale guide.)
What actually moves your price
- Carpentry run — built-ins by the foot; a 3-room has less wall to line, but a full kitchen plus two wardrobes still adds up.
- Material tier — laminate vs quartz countertop, vinyl vs timber, builder-grade vs branded fittings.
- Ceiling and lighting — false ceilings with cove lighting add S$1,500–S$3,000. (See false ceiling & lighting.)
- ID vs contractor — an interior designer adds ~10–20%.
- Scope creep — the usual budget-buster.
Cost by BTO town
3-room BTOs appear in both newer and mature-estate launches:
- Punggol, Tengah, Tampines North — first-time owners and singles often keep it lean and functional. Browse pros in Punggol and Tampines.
- Mature-estate BTOs — some owners spend more per square foot for premium finishes; see Bishan.
Sample budget — standard 3-room BTO
- Kitchen ≈ S$11,000
- Bathroom(s) ≈ S$8,000
- 2 bedrooms (wardrobes, flooring) ≈ S$10,000
- Living/dining (flooring, TV console, lighting) ≈ S$6,500
- Aircon System 2–3 ≈ S$2,500
- Painting + lighting + sundries ≈ S$2,500
- Subtotal ≈ S$40,500, plus 10% contingency (~S$4,000)
That lands most standard 3-room BTOs in the S$40,800–S$52,500 zone for works alone.
Renovation timeline
A clean 3-room BTO is among the fastest renovations:
| Week | Stage |
|---|---|
| 1–2 | Carpentry templating, electrical/plumbing first-fix, masonry |
| 3–4 | Carpentry installation, tiling, false ceiling |
| 5–6 | Painting, flooring, lighting, sanitaryware |
| 7–8 | Aircon, defects rectification, handover and clean |
Most 3-room BTO renovations complete in 6–8 weeks.
Financing your renovation
- Renovation loans are capped at the lower of 6× monthly income or S$30,000, typically over 1–5 years — often more than enough to cover a 3-room job.
- It's separate from your HDB housing loan and not payable by CPF.
- Pay by milestone — 10% deposit, progressive payments, and a 5–10% retention released after defects are cleared.
The costs people forget
- GST (9%) — confirm it's included.
- Contingency (10%) — keep it in reserve.
- Furniture & appliances — a separate S$8,000–S$15,000 budget.
- HDB OCS components — don't double-budget if you took HDB's optional flooring/fittings.
- Carpentry creep — even small flats balloon with extra built-ins.
HDB rules worth knowing
- 3-year tile rule — no removing bathroom/toilet tiles for 3 years from key collection.
- Licensed trades — PUB-licensed plumber, Licensed Electrical Worker (LEW); HDB-licensed, CaseTrust-accredited contractor.
- Permits — your contractor applies; structural changes need a PE endorsement.
- Permitted hours — noisy work Mon–Sat 9am–6pm; none Sundays/PHs.
- Timeline — about 6–8 weeks.
How to keep the bill sensible
- Scope carpentry tightly — a 3-room's smaller footprint rewards restraint.
- Overlay vinyl flooring over the flat BTO base.
- Stage non-essentials for later.
- Keep 10% contingency.
