Most renovation cost guides in Singapore quote you the contractor’s portion and stop there. That number looks manageable until you add aircon, curtains, loose furniture, kitchen appliances, mattresses and the hundred other things a livable home requires. By that point the S$65,000 “renovation budget” has quietly become a S$95,000 total spend and the couple is trying to figure out where the extra S$30,000 went.
This guide covers the true all-in cost of renovating a Singapore home in 2026 not just the contractor’s invoice but every category of spend between receiving the keys and sleeping in the finished flat for the first time. Written honestly by the team at RS Carpentry, who have been delivering whole-unit renovations long enough to know exactly where the money goes that nobody plans for.
Category One: The Renovation Contractor’s Scope
This is what most homeowners budget for and it covers hacking, masonry, wet works, carpentry, electrical, ceiling works, painting, glass and handover. For a 4-room HDB BTO in 2026 at mid-range specification, this sits between S$65,000 and S$95,000. For a 4-room resale HDB with significant hacking and waterproofing, it is S$70,000 to S$120,000. For a 3-bedroom condo the range is S$90,000 to S$170,000.
The variation within these ranges comes almost entirely from carpentry specification. The electrical, wet works and ceiling scopes are relatively fixed for a given flat size. The carpentry varies enormously based on plywood grade, laminate brand, hardware quality and the number of rooms that get full joinery treatment.
For the detailed breakdown of how renovation cost is allocated across trades, our guide on renovation budget Singapore 2026 covers the full picture.
Category Two: Aircon
A complete aircon installation for a 4-room HDB (covering living room, master bedroom and one or two additional bedrooms) costs S$3,500 to S$5,500 for a quality multi-split system from Mitsubishi Electric, Daikin or Panasonic, fully installed. This is almost never included in a renovation contractor’s quotation and almost always comes as a shock to first-time renovators who assumed it would be.
Aircon planning has to happen before the false ceiling is designed and built. The fan coil unit positions, trunking route and drainage path all affect the ceiling bulkhead design and the electrical circuit planning. Leaving aircon until after renovation starts creates expensive coordination problems. Our guide on aircon and electrical planning for Singapore renovation covers the full coordination sequence.
Category Three: Window Treatments
Curtains and blinds for a 4-room HDB flat cost S$2,500 to S$6,000 for a decent quality installation covering all rooms. The variation depends on the number of windows, the type of treatment (blackout roller blinds versus full-length linen curtains) and the fabric quality. Motorised blinds or curtains controlled by a home automation system add S$3,000 to S$8,000 on top depending on the number of points.
Most couples budget S$1,000 to S$1,500 for curtains and then spend two to three times that when they see what quality window treatments actually cost. Getting proper sunlight and privacy control in a Singapore flat is not optional and cheap curtains look cheap in an otherwise well-finished home.
Category Four: Loose Furniture
A complete set of loose furniture for a 4-room HDB, covering the sofa, dining table and chairs, coffee table, beds for three bedrooms and bedside tables, costs S$12,000 to S$25,000 for mid-range quality. Budget-conscious couples working with IKEA and occasional local finds can bring this closer to S$8,000 to S$14,000. Premium furniture from established Singapore or international brands easily hits S$30,000 to S$50,000 for the same set.
The furniture budget is where scale errors most commonly occur. Homeowners visualise the sofa and dining table but forget the console tables, shelving units, study chairs, floor lamps and the other pieces that fill a completed home. A useful planning approach is to list every freestanding item the flat needs and price each one before committing to a renovation scope, so the two budgets balance against each other.
Category Five: Kitchen Appliances
A functional kitchen appliance set for a Singapore HDB covers: refrigerator, washing machine, integrated hood and hob (usually included in the kitchen renovation but sometimes quoted separately), oven or microwave, water heater and dishwasher if applicable. Budget realistically:
- Refrigerator: S$1,200 to S$3,500 for a mid-range two-door model
- Washing machine: S$800 to S$1,800
- Hood and hob: S$800 to S$2,500 depending on brand and type
- Water heater: S$400 to S$1,200 per unit (most HDB flats need two)
- Oven or microwave combo: S$600 to S$2,000
Category Six: Mattresses and Soft Furnishings
Mattresses are where most couples significantly underspend relative to how much time they will spend using them. A quality mattress for the master bedroom costs S$1,500 to S$3,500. Children’s or guest room mattresses are S$600 to S$1,500 each. Add pillows, duvets, bed linen, rugs and throws and the soft furnishing bill for a 4-room flat sits between S$3,000 and S$8,000 for a comfortable mid-range setup.
The Real All-In Number
A realistic total-cost-of-occupancy for a 4-room HDB BTO renovation in Singapore in 2026, from empty flat to fully furnished and livable home:
- Renovation contractor scope: S$65,000 to S$95,000
- Aircon installation: S$3,500 to S$5,500
- Window treatments: S$2,500 to S$6,000
- Loose furniture: S$12,000 to S$25,000
- Kitchen appliances: S$4,000 to S$9,000
- Mattresses and soft furnishings: S$3,000 to S$8,000
- Miscellaneous (mirrors, artwork, plants, lighting fixtures not in reno scope): S$2,000 to S$5,000
- Total: S$92,000 to S$153,000
These numbers are not designed to alarm. They are designed to replace the surprise that hits couples six weeks into a renovation when they realise the flat will cost significantly more to furnish and equip than the contractor’s quotation suggested. Planning for the real number from the start produces better outcomes than adjusting downward mid-project.
How to Finance the Full Scope
Renovation loans in Singapore can cover up to S$30,000 of the contractor’s scope at flat rates of 3.88 to 4.18 percent per annum. They do not cover furniture, appliances or aircon. CPF savings can be used for the flat purchase but not for renovation costs. The honest conversation is about liquid savings: how much the couple has available and how much the complete move-in realistically costs at the quality level they want. Our renovation loan Singapore guide covers the mechanics in full.
