Bathroom Renovation Cost Singapore 2026

How much does a bathroom renovation cost in Singapore in 2026? There is no single reliable price for every bathroom. A refresh that retains sound finishes is fundamentally different from overlaying tiles, hacking and rebuilding the wet area, replacing plumbing, reinstating waterproofing or changing the layout and sanitary fittings.

The useful first answer is therefore scope-based. RenoExpert currently publishes one verified bathroom price: $8,999 for a defined two-bathroom resale renovation package. It is not a one-bathroom market rate, and it should not be divided by two. Work outside that package or a bathroom with different measurements, conditions and selections needs a site-specific quotation.

How Much Does Bathroom Renovation Cost in Singapore?

A headline price is meaningful only when the bathroom count, work areas, material responsibility, installation labour and exclusions are clear. A quotation for overlaying selected surfaces cannot be compared directly with one that removes the existing bathroom and reinstates the wet-area system.

What Is Included in a Bathroom Renovation?

A complete quotation may combine several trades, but the exact inclusions vary. Two totals can differ because one includes removal, substrate repair and reinstatement while another assumes that existing surfaces and services remain.

1. Protection of retained areas and access routes
2. Dismantling or hacking of agreed tiles, fixtures and built-ins
3. Debris clearing and haulage where stated
4. Substrate or screed preparation
5. A separately defined waterproofing scope
6. Floor and wall tiling
7. Plumbing modifications and connections
8. Installation of stated sanitary fittings and accessories
9. Shower screen, ceiling, electrical or painting work where quoted
10. Cleaning, inspection and handover items where included

Bathroom Renovation Cost Breakdown

Hacking and Removal

The agreed removal may include floor tiles, wall tiles, the entrance kerb, vanity, toilet bowl, basin, shower screen and accessories. Labour, protection, bagging, haulage, disposal and later make-good should be identified rather than treated as one vague hacking line.

Waterproofing

Bathroom waterproofing is a hidden membrane or system below the finished tiles. Its cost is affected by substrate preparation, the defined floor and wall areas, junctions, penetrations, screed work and whether the existing system has been disturbed. Tiles and grout are not the waterproofing system.

Tiling

Floor and wall tiling scope depends on measured area, substrate condition, tile dimensions, setting-out, cuts, corners, niches, pattern, grout and edge finishing. Owner-supplied tiles still affect labour and planning because their size and layout change the installation work.

Plumbing

Plumbing can include hot and cold piping, basin and tap connections, shower or mixer points, toilet supply and waste alignment, heater plumbing and drainage coordination. Replacing a fixture at an existing point is different from moving the point or changing the route.

Sanitary Fittings and Accessories

Toilet bowls, basins, taps, shower sets, mixers, mirrors, accessories and shower screens may be homeowner-supplied or contractor-supplied. Confirm product supply, delivery, installation, connectors, modifications and disposal of the old item. Product warranty responsibility should follow the actual supplier and written terms rather than an assumption.

Electrical Coordination

A bathroom project may need coordination for heater points, lighting or suitable ventilation-related electrical work. Electrical work is not automatically included in every bathroom quotation and should be assessed and listed separately where required.

Renovating One Bathroom vs Two Bathrooms

Two bathrooms do not necessarily cost exactly twice as much as one. Mobilisation, protection, haulage and project coordination may be shared, while bathroom size, plumbing changes, waterproofing and tile areas, sanitary selections and shower-screen requirements can differ substantially between the master and common bathroom.

RenoExpert’s verified package applies to two resale bathrooms under its stated scope. It should not be converted into a one-bathroom rate or assumed to cover a different property, layout or selection schedule.

Overlay vs Full Hacking: Which Costs More?

Overlay can involve less removal, but it is not automatically the correct or lowest-cost long-term scope. Existing tile bond, substrate, floor buildup, door clearance, drainage, floor falls, defects and the condition of the underlying waterproofing all matter.

Overlay does not automatically renew waterproofing. Conversely, hacking should not be specified merely because it is more extensive. The decision belongs to the existing condition and intended renovation scope.

How Waterproofing Affects Bathroom Renovation Cost

When hacking removes or compromises the existing wet-area system, waterproofing reinstatement should not be treated as an invisible optional extra. The work may depend on substrate repair, screed, defined membrane areas, junctions, penetrations, curing and protection before tiles are installed.

When Plumbing Makes Bathroom Renovation More Expensive

Cost can increase when piping is replaced, hot and cold routes are added, basin or shower points move, waste alignment changes, heater plumbing is added, or concealed routes require access and make-good. Existing versus new positions should therefore be marked clearly on the floor plan or site.

A leak may originate from a supply pipe, trap, waste connection or sanitary fitting rather than waterproofing. The symptoms alone do not prove which trade is responsible, so the likely source should be reviewed before repair work is priced.

How Tile Choice Changes the Budget

Tile product price is only one part of the decision. Size, pattern, wall coverage, floor coverage, niches, corners, cut-outs, grout details and wastage can change the installation effort. Large formats and intricate layouts can require different setting-out and cutting from a straightforward layout.

The verified RenoExpert two-bathroom package states that homeowners supply homogeneous floor tiles and ceramic wall tiles, while the package covers the described laying labour. Confirm dimensions and quantities early so suitability, delivery and any variation in labour can be reviewed before installation.

Owner-Supplied vs Contractor-Supplied Materials

Bathroom Renovation Costs Homeowners Often Miss

• Protection outside the bathroom
• Bagging, haulage and disposal
• Substrate repair discovered after hacking
• Screed reinstatement and floor-level correction
• Plumbing relocation rather than simple replacement
• Electrical points for heaters, lights or related equipment
• Shower screen and measured installation
• Ceiling preparation and painting
• Additional tile cuts, niches, patterns or edge treatment
• Make-good around new or removed services
• Concealed conditions that could not be confirmed before opening up
• Variation work requested after the quotation is agreed

How to Compare Bathroom Renovation Quotations

Compare the work line by line before comparing the final total. Two quotations may use similar headings while making different assumptions about removal, products, quantities and reinstatement.

Typical Bathroom Renovation Sequence

1. Protect retained areas and access routes
2. Dismantle or hack the agreed scope
3. Complete planned plumbing modifications
4. Repair the substrate or reinstate screed where required
5. Apply the specified waterproofing system
6. Install floor and wall tiles
7. Complete stated ceiling, painting or electrical work
8. Install sanitary fittings
9. Install the shower screen and accessories where included
10. Complete applicable checks, cleaning and handover

The order can change with the actual design, system requirements, access and other renovation work. The important point is to coordinate dependencies: waterproofing follows suitable preparation, tiles follow the agreed wet-area process, and fittings should suit the completed points and finishes.

How Long Does Bathroom Renovation Take?

The current verified RenoExpert content does not publish a universal bathroom duration, so this guide does not invent one. Programme depends on hacking, substrate condition, waterproofing and curing requirements, tile complexity, plumbing changes, product availability, one versus two bathrooms, site restrictions and the timing of shower screens or owner-supplied items.

Ask the quotation or project schedule to identify dependencies and selection deadlines. A realistic sequence is more useful than a generic number that ignores the bathroom’s condition and scope.

What to Send for an Accurate Bathroom Quotation

• Property type and current bathroom photos or video
• Floor plan if available
• Whether the enquiry covers one or two bathrooms
• Whether overlay or hacking is being considered, if known
• Visible leakage or moisture locations without assuming the cause
• Sanitary fitting and accessory requirements
• Any intended plumbing or layout changes
• Preferred start period and relevant site restrictions

A site visit may still be needed to confirm measurements, access and visible condition. The most useful quotation is not simply the lowest total; it is the one whose scope, material responsibility, exclusions and variation process you can understand before work begins.
