5 Room HDB Renovation Cost Singapore (2026 Price Guide)
Renovating a 5-room HDB flat is one of the biggest financial commitments most homeowners make after purchasing their property. Whether you’ve just collected the keys to a new Build-to-Order (BTO) flat or bought a resale unit, understanding the full renovation cost is essential before work begins.
Many homeowners start with a rough budget, only to realise later that the final bill is much higher than expected. The reason is simple—renovation costs vary widely depending on the condition of the flat, the amount of built-in carpentry, material choices, labour costs, and the overall design.
This guide breaks down everything you need to know about 5 room HDB renovation cost in Singapore. You’ll find realistic price ranges, detailed cost breakdowns, budgeting advice, common hidden expenses, and practical tips to help you plan your renovation with confidence.
The average 5 room HDB renovation cost in Singapore ranges from S$60,000 to more than S$120,000, depending on the age of the flat, renovation scope, and the quality of materials used.
| Flat Type | Estimated Renovation Cost |
|---|---|
| 5 Room BTO | S$60,000 – S$85,000 |
| 5 Room Resale | S$75,000 – S$120,000+ |
In general, resale flats cost more to renovate because they often require demolition, electrical rewiring, plumbing replacement, waterproofing, and other repair work before the new renovation can begin.
What Is the Average 5 Room HDB Renovation Cost in Singapore?
The total renovation budget depends on the amount of work involved, the materials you choose, and the level of customisation you want for your home.
As a general guide, most homeowners fall into one of these three renovation categories.
| Renovation Level | Estimated Budget |
| Basic | S$60,000 – S$70,000 |
| Mid-Range | S$70,000 – S$90,000 |
| Premium | S$90,000 – S$120,000+ |
A basic renovation usually covers essential improvements such as painting, vinyl flooring, standard kitchen cabinets, lighting installation, and simple bathroom upgrades.
A mid-range renovation often includes customised carpentry, better-quality finishes, decorative lighting, feature walls, additional storage solutions, and upgraded bathroom fittings.
A premium renovation focuses on high-end materials and bespoke design features. This may include custom-built furniture, premium kitchen systems, designer lighting, smart home automation, luxury countertops, and imported finishes.
5 room hdb renovation cost vs Resale Renovation Cost
Whether your flat is a new BTO unit or a resale property has a major impact on your renovation budget.
| Feature | BTO | Resale |
| Average Cost | Lower | Higher |
| Hacking Required | Rare | Common |
| Plumbing Replacement | Usually No | Often Required |
| Electrical Rewiring | Minimal | Frequently Needed |
| Flooring Replacement | Optional | Common |
| Renovation Duration | Shorter | Longer |
BTO Renovation
A newly completed BTO flat already has a solid foundation, which means less structural work is usually required. Many homeowners choose to retain the existing flooring or bathroom fittings where possible, helping to reduce renovation costs.
Since the electrical system and plumbing are new, fewer repairs are typically needed, allowing more of the budget to be spent on design improvements and customised storage.
Resale Renovation
Renovating a resale flat is often more expensive because older homes may have hidden issues that are only discovered once work begins.
Common upgrades include:
- Hacking old flooring and wall tiles
- Replacing ageing plumbing
- Electrical rewiring
- Waterproofing bathrooms
- Repairing damaged walls
- Levelling uneven floors
These additional works can significantly increase the overall renovation budget, especially in older HDB flats.

Understanding where your renovation budget goes makes it easier to plan your finances and prioritise spending.

| Renovation Work | Estimated Cost (SGD) |
| Carpentry | 12,000 – 30,000 |
| Kitchen Renovation | 8,000 – 20,000 |

| Air Conditioning | 4,000 – 8,000 |
| Lighting | 1,000 – 3,000 |
| False Ceiling | 2,000 – 6,000 |
Carpentry
Custom carpentry is often the single largest renovation expense.
Built-in kitchen cabinets, wardrobes, TV consoles, study desks, shoe cabinets, and storage units are designed to maximise space, but they also add significantly to the total renovation cost.
The final price depends on the materials, finishes, hardware, and overall design complexity.
Kitchen Renovation
The kitchen is one of the busiest areas of any home, so homeowners usually invest more in this space.
A typical kitchen renovation may include:
- Kitchen cabinets
- Countertops
- Sink and mixer
- Backsplash
- Lighting
- Built-in appliances
- Soft-close drawers and hinges
Premium countertop materials and custom cabinetry can increase the overall budget considerably.
Bathroom Renovation
Bathroom renovation costs vary depending on the amount of work required.
Typical upgrades include replacing wall and floor tiles, waterproofing, sanitary fittings, shower screens, vanity cabinets, toilets, and plumbing fixtures.
Older resale flats often require more extensive bathroom work than newer BTO units.
Flooring
Flooring plays a major role in both appearance and durability.
Popular flooring choices include:
- Vinyl flooring
- Homogeneous tiles
- Porcelain tiles
- Laminate flooring
- Engineered wood
Each material offers different benefits in terms of cost, maintenance, durability, and installation time.
What Factors Affect Your Renovation Budget?
No two renovation projects cost exactly the same. Even two 5-room HDB flats in the same neighbourhood can have very different budgets depending on the scope of work and the materials selected.
Understanding the main cost drivers will help you set a realistic budget and avoid unexpected expenses later in the project.
Flat Condition
The condition of your flat is one of the biggest factors affecting renovation costs.
A new BTO flat usually requires minimal structural work because the plumbing, electrical system, and flooring are already in good condition. In contrast, an older resale flat may need extensive repairs before any interior upgrades can begin.
Additional work may include:
- Removing old flooring
- Hacking wall tiles
- Replacing old plumbing
- Electrical rewiring
- Repairing damaged walls
- Waterproofing bathrooms
These essential repairs can add several thousand dollars to the overall renovation budget.
Design Style
The design style you choose also affects the total cost.
A clean, minimalist design generally requires fewer built-in features and decorative elements, making it one of the most budget-friendly options.
More elaborate styles, such as luxury contemporary, Japandi, industrial, or modern classic interiors, often involve customised carpentry, premium finishes, feature lighting, and higher-quality materials, all of which increase the overall investment.
Materials
Material selection has a direct impact on renovation costs.
For example, quartz or sintered stone countertops typically cost more than solid surface options. Similarly, porcelain tiles are generally more expensive than standard ceramic tiles.
Choosing durable, high-quality materials may require a larger upfront investment, but they often offer better long-term value through improved durability and lower maintenance.
Carpentry
Built-in carpentry is usually one of the most expensive parts of a renovation.
Common carpentry items include:
- Kitchen cabinets
- Wardrobes
- TV feature walls
- Shoe cabinets
- Study desks
- Display shelves
- Storage benches
The more customised storage you add, the higher your renovation cost will be.
Labour Costs
Labour costs continue to influence renovation pricing in Singapore.
Skilled trades such as carpentry, tiling, plumbing, electrical work, painting, and ceiling installation each contribute to the overall project cost. Complex designs or custom installations typically require more labour hours, increasing the final quotation.
Project Scope
The size of your renovation naturally affects the budget.
A simple refresh with painting, lighting, and flooring costs much less than a complete home renovation that includes hacking, custom carpentry, bathroom upgrades, and a redesigned kitchen.
Clearly defining your renovation priorities before requesting quotations can help you stay within budget.
Room-by-Room Renovation Cost Estimate
Breaking your budget down by room makes it easier to understand where most of your money will be spent.

Common renovation works include:
- TV feature wall
- Built-in storage
- False ceiling

- Toilet replacement

Planning this space properly can improve daily convenience and keep household items organised.
Budget vs Mid-Range vs Luxury Renovation
Not every homeowner needs a premium renovation. Choosing the right renovation level depends on your lifestyle, long-term plans, and available budget.
| Feature | Budget | Mid-Range | Luxury |
| Flooring | Vinyl | Premium Vinyl or Tiles | Imported Tiles or Engineered Wood |
| Kitchen | Standard Cabinets | Custom Cabinets | Premium Designer Kitchen |
| Lighting | Basic Fixtures | Decorative Lighting | Designer Lighting System |
| Carpentry | Limited | Moderate | Extensive Custom Carpentry |
| Smart Home | Not Included | Optional | Fully Integrated |
Budget Renovation
A budget renovation focuses on essential upgrades without unnecessary customisation.
This option is suitable for homeowners who want a clean, modern home while keeping costs under control.
Mid-Range Renovation
A mid-range renovation offers a balance between quality, functionality, and design.
Many homeowners choose this option because it includes customised storage, improved finishes, and better-quality materials without reaching luxury-level pricing.
Luxury Renovation
Luxury renovations prioritise premium materials, customised craftsmanship, and personalised design.
These projects often include:
- Full-height custom cabinetry
- Smart home automation
- Designer lighting
- Premium countertops
- Imported finishes
- High-end appliances
While this option delivers a distinctive home, it also comes with the highest renovation budget.
Hidden Renovation Costs Most Homeowners Forget
Many first-time homeowners focus only on the contractor’s quotation. However, the quotation rarely covers every expense involved in moving into a completed home.
Planning for these additional costs can prevent unnecessary financial stress later.
Common hidden expenses include:
- Kitchen appliances
- Refrigerator
- Washing machine
- Dryer
- Furniture
- Curtains and blinds
- Decorative lighting
- Smart home devices
- Internet installation
- Cleaning after renovation
- Disposal fees
- Moving services
- Minor repairs after handover
- Variation orders requested during construction
It is also wise to keep a contingency fund of 5% to 10% of your renovation budget. This extra reserve can help cover unexpected issues without affecting the rest of your financial plans.
Interior Designer vs Contractor
One of the most common questions homeowners ask is whether they should hire an interior designer or work directly with a renovation contractor.
Both options have advantages, and the right choice depends on your budget, renovation goals, and how involved you want to be throughout the project.
| Interior Designer | Contractor |
| Provides complete design solutions | Focuses mainly on renovation work |
| Manages the entire project | Carries out construction based on agreed plans |
| Recommends layouts and materials | Suitable for straightforward renovations |
| Usually higher overall cost | Generally lower renovation cost |
Pros of Hiring an Interior Designer
- Professional space planning
- Creative design ideas
- Better coordination between trades
- Material recommendations
- Complete project management
- Less day-to-day involvement for homeowners
Cons of Hiring an Interior Designer
- Higher professional fees
- More expensive overall renovation packages
- Design revisions may extend the project timeline
Pros of Hiring a Contractor
- Lower renovation costs
- Direct communication
- Faster decision-making
- Suitable for homeowners with a clear renovation plan
Cons of Hiring a Contractor
- Limited design support
- Greater responsibility for project coordination
- More owner involvement throughout the renovation process
How to Reduce Your 5 Room HDB Renovation Cost
A beautiful home does not always require a six-figure renovation budget. With careful planning and smart decisions, you can reduce costs without compromising comfort or quality.
The key is to spend on features that add long-term value while avoiding unnecessary upgrades.
Expert Tips to Save Money
Compare multiple quotations
Request at least three detailed quotations before making a decision. Comparing prices, materials, warranties, and the scope of work will give you a better understanding of market rates and help you identify unusually low or high quotes.
Keep existing finishes where possible
If your flooring, bathroom tiles, or doors are still in good condition, consider keeping them. Reusing existing finishes can significantly reduce demolition and replacement costs.
Limit custom-built carpentry
Built-in storage is useful, but too much custom carpentry can quickly inflate your budget. Where practical, combine built-in units with ready-made furniture.
Choose durable, practical materials
Expensive materials do not always offer better value. Focus on products that are easy to maintain, durable, and suitable for everyday family use.
Plan your layout carefully
Changing the layout after work has started often leads to additional labour costs and material wastage. Finalise your design before construction begins.
Buy appliances during promotions
Large appliances such as refrigerators, washing machines, ovens, and air conditioners frequently go on sale. Purchasing them during promotional periods can result in substantial savings.
Prioritise essential upgrades
Focus your budget on areas you use every day, such as the kitchen, bathrooms, and storage. Decorative features can always be added later if your budget allows.
Sample Budget for a 5 Room HDB Renovation
The example below illustrates how a mid-range renovation budget might be allocated. Actual costs will vary depending on your design preferences, material choices, and the condition of the flat.
| Category | Estimated Budget |
|---|---|
| Kitchen | S$15,000 |
| Bathrooms | S$12,000 |
| Carpentry | S$22,000 |
| Flooring | S$8,000 |
| Electrical Works | S$5,000 |
| Plumbing | S$3,000 |
| Painting | S$3,000 |
| Furniture | S$10,000 |
| Appliances | S$12,000 |
| Contingency Fund | S$8,000 |
This sample highlights an important point: the contractor’s quotation is only part of the overall cost. Furniture, appliances, and contingency planning should also be included in your budget from the start.
Renovation Timeline
A well-planned renovation usually takes 8 to 12 weeks, although larger or more complex projects may require additional time.
The timeline below provides a general overview of each stage.
| Stage | Typical Duration |
| Planning & Budgeting | 1–2 Weeks |
| Design Development | 1–2 Weeks |
| Material Selection & Approval | About 1 Week |
| Demolition | Around 1 Week |
| Wet Works | 2 Weeks |
| Carpentry Fabrication & Installation | 3–4 Weeks |
| Final Installations | 1–2 Weeks |
| Inspection & Handover | Around 1 Week |
Several factors can affect the schedule, including:
- Custom-made carpentry
- Material delivery delays
- Design changes during construction
- Additional repair work discovered after demolition
- Public holidays and contractor availability
Allowing some flexibility in your timeline can help reduce stress if unexpected delays occur.
Common Renovation Mistakes
Renovating a home is a significant investment, and avoiding common mistakes can save both time and money.
Choosing the Cheapest Quote
The lowest quotation is not always the best value.
A lower price may exclude important items, use lower-quality materials, or leave out essential services that later become additional charges. Always compare the scope of work instead of looking only at the total price.
Forgetting Hidden Costs
Many homeowners budget only for renovation works and overlook expenses such as:
- Furniture
- Kitchen appliances
- Curtains and blinds
- Decorative lighting
- Moving services
- Cleaning after renovation
Including these items in your financial plan will give you a more realistic overall budget.
Spending Too Much on Carpentry
Custom-built storage is attractive, but every additional cabinet increases your renovation cost.
Think carefully about what you genuinely need. A combination of built-in storage and freestanding furniture often provides a better balance between functionality and cost.
Not Keeping a Contingency Fund
Unexpected expenses are common, particularly in older resale flats.
Setting aside 5% to 10% of your renovation budget gives you the flexibility to deal with unforeseen repairs without affecting the rest of your finances.
Making Design Changes Midway
Changing layouts, materials, or finishes after construction has started can delay the project and increase labour costs.
Finalise your design decisions before renovation work begins to avoid unnecessary variation orders.
Ignoring the Contract
Always read your renovation contract carefully.
Check that it clearly states:
- Scope of work
- Materials and finishes
- Payment schedule
- Project timeline
- Warranty period
- Defect rectification process
A detailed agreement helps prevent misunderstandings throughout the renovation.
Skipping the Final Inspection
Before making the final payment, inspect every area of your home carefully.
Look for:
- Paint defects
- Uneven tiles
- Loose fittings
- Scratches
- Water leaks
- Faulty electrical points
- Cabinet alignment
Recording defects early makes it easier to have them corrected before the project is officially completed.
Frequently Asked Questions
How much does a 5 room HDB renovation cost in Singapore?
Most homeowners spend between S$60,000 and S$120,000, depending on whether the flat is a BTO or resale unit, the amount of renovation work required, and the materials selected.
Is S$80,000 enough for a 5 room HDB renovation?
For many BTO flats, a budget of S$80,000 is generally sufficient for a comfortable mid-range renovation. Older resale flats often require a larger budget because of additional repair work and replacement of ageing systems.
Why is renovating a resale HDB more expensive?
Resale flats usually require more preparatory work, including hacking, electrical rewiring, plumbing replacement, waterproofing, and repairs to ageing finishes. These additional works increase both labour and material costs.
What is usually included in a renovation quotation?
Most renovation quotations include demolition, carpentry, flooring, painting, plumbing, electrical work, project management, and installation. Furniture, household appliances, curtains, and decorative accessories are often quoted separately.
How long does a 5 room HDB renovation take?
Most projects are completed within 8 to 12 weeks, although larger renovations or projects involving custom carpentry may take longer.
Should I hire an interior designer or a contractor?
If you need professional design advice, space planning, and project management, an interior designer may be the better choice. If you already have a clear renovation plan and want to reduce costs, working directly with a contractor may be more suitable.
How many renovation quotations should I get?
It is advisable to obtain at least three detailed quotations. This allows you to compare pricing, workmanship, materials, warranties, and the scope of work before making a decision.
Can I renovate my home in stages?
Yes. Many homeowners complete essential works first and postpone decorative upgrades until a later stage. Renovating in phases can help manage cash flow more effectively.
What hidden costs should I prepare for?
Besides renovation work, remember to budget for:
- Furniture
- Appliances
- Curtains
- Lighting
- Smart home systems
- Moving expenses
- Cleaning services
- Contingency for unexpected repairs
Final Verdict
Planning your 5 room HDB renovation cost starts with understanding where your money will be spent. While most homeowners budget between S$60,000 and S$120,000, the final cost depends on the condition of the flat, the amount of custom carpentry, your choice of materials, and the overall scope of work.
Rather than choosing a contractor based solely on price, compare detailed quotations, check the quality of materials, review completed projects, and understand exactly what is included before signing any agreement.
A realistic budget, careful planning, and a contingency fund will help you manage costs more effectively and reduce the risk of unexpected expenses. By taking the time to plan each stage properly, you can create a comfortable, functional home that suits both your lifestyle and your long-term budget.
