HDB Renovation Cost Singapore 2026: A Practical Price Guide for Homeowners

How much does an HDB renovation cost in Singapore in 2026? As a broad market reference, published estimates place full renovations at about $40,800 to $76,500 for BTO flats and $55,000 to $98,900 for resale flats, depending on flat size. These are market benchmarks across projects with different scopes, not a price every homeowner must spend.

RenoExpert’s published full-house resale makeover packages start from $20,999 for a 3-room, $22,999 for a 4-room, $24,999 for a 5-room and $26,999 for an Executive Apartment. These are defined starting packages: some products are supplied by the homeowner, and several trades or upgrades are priced separately.

The distinction matters: a Singapore market benchmark, a RenoExpert starting package and the final quotation for one home are three different figures. Compare scope, quantities, materials, exclusions and site conditions before comparing totals.

HDB Renovation Cost in Singapore for 2026

Qanvast’s February 2026 guide projected renovation ranges using 2025 median costs from 341 BTO projects and 449 resale projects, adjusted for estimated inflation of 1% to 2%. Its figures provide a useful snapshot across many projects, but they combine homes with different designs, carpentry quantities, finishes and existing conditions.

Treat these ranges as planning references rather than quotations. Two 4-room flats can sit far apart in cost when one retains its floors and carpentry while the other needs extensive hacking, rewiring, new built-ins and rectification work. The best comparison is a like-for-like scope with similar quantities and material allowances.

RenoExpert Full-House Renovation Starting Prices

RenoExpert’s published starting packages are designed as practical entry points for resale HDB full makeovers. They are not fixed final prices for every flat. Measurements, the property’s condition, design choices, material selections and work outside the base scope determine the final quotation.

The starting prices and market ranges should not be treated as like-for-like alternatives. RenoExpert’s package has a defined base scope and homeowner-supplied finish products, while market datasets can include extensive customisation, more carpentry, premium materials and additional trades. Read the inclusions, quantities and exclusions before drawing a comparison.

What the Starting Full-House Package Includes

The package brings together core full-house renovation work under one coordinated project. Its defined scope covers applicable hacking and removal, masonry and tiling, plumbing and sanitary installation labour, the stated kitchen carpentry and quartz quantities, and relevant site support. Exact areas, quantities and project-specific additions belong in the written quotation.

Planning and Project Coordination

The process can include a professional design consultation and space planning, 3D visuals, material and colour selection, project management and site supervision. These steps translate a homeowner’s priorities into an agreed scope and help different trades work in the correct sequence. They do not remove the need for the homeowner to approve drawings, finishes and quotation details.

Hacking and Removal

For a full makeover, the agreed work may cover hacking in the kitchen and bathrooms, dismantling kitchen cabinets and bases, removing relevant existing flooring, and clearing the resulting debris. The actual work depends on what is present and what the approved design retains. Additional hacking discovered or requested after confirmation should be documented rather than assumed.

Masonry, Waterproofing and Tiling

Relevant work can include waterproofing, cement screeding and laying floor or wall tiles in kitchens and bathrooms, together with specified floor areas and skirting. Tile dimensions, laying pattern, substrate condition and the amount of making-good can all affect labour. Homeowners should check whether the quote states areas or quantities rather than relying on a general line such as ‘tiling works’.

Plumbing and Sanitary Installation

The applicable package scope can include plumbing works and installation labour for covered sanitary fixtures supplied by the homeowner. Confirm the number and location of basins, taps, toilet bowls, heaters and accessories, as well as whether pipe rerouting is needed. A simple replacement is different from changing the bathroom layout or adding new points.

Kitchen Carpentry and Quartz

RenoExpert’s full-house resale makeover package includes 10 ft of bottom kitchen cabinets, 10 ft of top kitchen cabinets and 10 ft of quartz countertop. Additional cabinet length, extra storage, specialised internal configurations or upgraded materials can increase the final quotation. The written quotation should confirm measurements and any additions for the individual kitchen.

Site Protection and Supporting Works

Supporting work can include protection, debris clearing, haulage, washing or final cleaning, specified bathroom doors and the HDB renovation permit fee according to the package scope. This does not automatically cover a Professional Engineer’s endorsement, engineering assessment, specialist report, unusual submission or unrelated authority charge. Any such requirement should be identified separately in the project quotation.

Items Usually Supplied by the Homeowner

In the starting package model, homeowners supply finish products such as floor and wall tiles, toilet bowls, basins, taps, water heaters, lights, fans and relevant bathroom accessories or fixtures. Where the agreed package covers their installation, the applicable installation labour is included. Product purchase prices remain outside the package unless the quotation says otherwise.

This arrangement gives homeowners control over appearance and product budget, but selections need to be made early. Tile dimensions can affect laying costs; sanitary products must suit available connections; and lights or fans must match the electrical plan. RenoExpert can help clients select suitable tiles and accessories and may accompany them to shops or showrooms as part of the selection process.

Common Exclusions and Add-Ons

The starting full-house price excludes electrical works or rewiring, whole-house painting, vinyl flooring and air-conditioning unless added to the quotation. It can also rise with more carpentry, a false ceiling, extra hacking, premium material or hardware upgrades, and bathroom work beyond the stated scope.

Some exclusions are separate specialist systems; others are design choices. For example, rewiring depends on assessed circuit needs and point quantities, while a false ceiling is optional. Ask for each addition to be priced and described, including quantities, so you can decide what is essential, what can be simplified and what can be completed later.

How Cost Changes by HDB Flat Type

3-Room HDB

A 3-room flat has less floor area, but that does not remove the fixed sequence of kitchen and bathroom wet work. Hacking, waterproofing, screeding, tiling and plumbing can still form a substantial scope. Decisions about retaining serviceable flooring, doors or carpentry can therefore change the amount of work materially.

4-Room HDB

Two 4-room flats can produce very different quotations. The condition and extent of two bathrooms, whether flooring is kept or replaced, measured carpentry length, planned electrical points and the amount of wall preparation all matter. Family storage requirements can also add wardrobes or built-ins beyond the starting scope.

5-Room HDB

A 5-room flat creates more potential flooring and painting area, more electrical points and more space for carpentry. Larger living and dining areas can also increase finishing quantities. Size raises the potential quantities, but the agreed work remains the main cost driver; a restrained scope can still involve less work than a heavily customised smaller flat.

Executive Apartment

Executive Apartments have larger measured areas and common spaces, creating more potential finishing, electrical and carpentry quantities. Additional storage can expand the scope further. A site survey and measured carpentry schedule are essential before turning the package starting point into a project-specific quotation.

BTO vs Resale HDB Renovation Cost

Resale work often has to deal with what already exists. In RenoExpert’s site experience, some—not all—resale flats have damaged or uneven walls, signs of dampness or moisture, or damaged doors and frames that need preparation, repair, making-good or replacement. The cause should not be assumed, and some conditions only become fully visible during inspection or after removal work.

Retention can reduce unnecessary work when elements are genuinely serviceable. Existing floors, doors, frames or carpentry may be kept if their condition and the new design allow it. Electrical wiring should only be retained after proper assessment; appearance or a do-it-yourself check is not enough to establish safety or suitability.

The Main Work Categories That Affect HDB Renovation Cost

Hacking and Disposal

Removal work creates labour, protection, haulage and disposal costs before new finishes are installed. Costs change with the surfaces involved, access, volume of debris and the amount of making-good. Keeping sound finishes can avoid this work, but only when levels, condition and the intended design are suitable.

Flooring and Tiling

Overlaying existing tiles is sometimes considered when the substrate and tiles are sound, floor levels and door clearances remain workable, and the project requirements permit it. It is not an automatic shortcut. Vinyl may also be an alternative in suitable dry areas, but it is project-dependent and not universally cheaper or better once preparation, trims and product quality are considered.

Carpentry

Carpentry is strongly influenced by measured run length, cabinet height and depth, internal drawers or organisers, laminate selections, hardware and feature details. A quotation that states only ‘kitchen cabinets’ cannot be compared reliably with one that states top and bottom lengths, countertop length and accessories.

Electrical Work

Rewiring and electrical additions are separate from RenoExpert’s starting full-house package. Cost depends on assessment, circuit and distribution-board needs, the number and type of points, routing, and whether installation is exposed or concealed. Finalise furniture, appliance and lighting positions early to reduce late point additions.

Bathrooms

Bathrooms combine hacking, waterproofing, screeding, tiling, plumbing, sanitary installation and doors in a compact area. Layout changes, extra fittings and substrate repair can add cost. Confirm which fixtures are owner-supplied, which installation work is covered, and how waterproofing is specified.

Painting and Finishing

Painting is priced separately from the starting package. The amount of preparation matters: walls with cracks, moisture damage, unevenness or old failing coatings require more work than sound walls. Colour count, specialist coatings and doors or ceilings in the paint scope should be explicit.

Why Similar Flats Can Have Different Renovation Costs

• Different amounts of hacking, repair and substrate preparation
• Different carpentry measurements, internal storage and hardware
• Retaining serviceable finishes versus replacing them
• Standard products versus premium tiles, quartz, laminates or fittings
• Different electrical point quantities and wiring condition
• Layout changes that move plumbing, walls or doors
• Access, protection, haulage and site constraints
• Design changes or additions after work begins

A realistic quote is a priced interpretation of one home and one design. If two quotes differ significantly, do not assume the lower contractor has found the same solution for less. First check whether quantities, materials, preparation, approvals, installation and exclusions match.

How to Compare HDB Renovation Quotations

Ask questions about vague descriptions before signing. ‘Supply and install cabinets’ should lead to questions about length, top and bottom units, internal finish, hardware and countertop. ‘Bathroom renovation’ should identify hacking, waterproofing, screeding, tiling, plumbing, fixtures and doors. A detailed quotation protects both homeowner and contractor by creating a shared reference.

Practical Ways to Reduce Renovation Cost

Retain What Is Serviceable

Keeping sound flooring, doors, frames or carpentry can reduce hacking, disposal and replacement. Retention should follow condition assessment and must still fit the new design. Do not retain electrical wiring merely because it looks acceptable.

Simplify the Layout and Carpentry

Avoid moving plumbing or walls without a functional reason. Prioritise storage where it solves a real need, use standard cabinet dimensions where practical and limit decorative built-ins that add cost without improving daily use.

Make Selections Early

Confirm tile sizes, sanitary products, appliances, lights, fans, laminates and colours before their installation windows. Early selections allow dimensions and services to be coordinated and reduce delay or rework.

Separate Needs from Upgrades

Place safety, water-tightness, essential repair and core functionality first. Price optional upgrades separately so they can be removed without disturbing the base scope. This is more useful than applying an arbitrary discount to an unclear quotation.

Understanding Variation Orders

A variation order records work added, removed or changed after the contract scope is agreed. Common examples include extra electrical points, design changes, premium upgrades and additional carpentry. Unexpected site conditions can also require extra work even when planning was careful.

Clear scope and early decisions can reduce avoidable Variation Orders. Confirm the design, electrical points, carpentry layout, materials and products before the relevant work begins. If a genuine change or unforeseen site condition requires additional work, ask for the description, price and effect on the programme to be documented before authorising it.

Direct Contractor vs Interior Designer

A direct contractor model can suit homeowners who want a practical scope, direct trade coordination and control over selections. An interior-design practice may place more emphasis on a highly customised design service and extensive concept development. Company labels alone do not determine quality or final price: compare the actual design support, drawings, supervision, scope detail, track record and communication offered.

RenoExpert’s package includes planning support such as consultation, space planning, 3D visuals, selection assistance and project supervision. Homeowners should still decide whether that service level matches their expectations, especially for complex bespoke interiors. Choose based on the working process and documented deliverables rather than a general assumption about contractor or designer pricing.

HDB Renovation Rules and Licensed Work

HDB homeowners should engage a contractor listed in HDB’s Directory of Renovation Contractors for applicable renovation work. Certain works require HDB approval or a renovation permit before they start, while work that does not require a permit must still follow the relevant guidelines and conditions. Requirements can change, so check the current HDB guidance for the proposed work.

Electrical installation work such as home wiring, power points and control units must be carried out or supervised by an Energy Market Authority licensed electrical worker where required. Regulated water service and sanitary plumbing work must be handled by a PUB licensed plumber, apart from limited simple work identified by PUB. Ask who is responsible for engaging and coordinating these licensed people.

What to Prepare for an Accurate Renovation Quotation

Start with the floor plan, clear photos or videos and a room-by-room requirements list. Include any existing drawings or design references. A site visit is normally needed before a detailed final quotation because measurements, access and concealed or surface conditions cannot be confirmed from a message alone.

RenoExpert’s package prices provide a defined starting point, while the 2026 market ranges provide broader context. Finalising the scope, electrical points, carpentry, tiles and accessories early can reduce avoidable variations. If a genuinely unforeseen site condition requires additional work, it should be discussed, documented and priced separately. The useful outcome is not the lowest headline but an itemised quotation that can be understood and managed.
