How much does a bathroom renovation cost in Singapore in 2026?

How much does a bathroom renovation cost in Singapore in 2026?

A standard HDB bathroom renovation in Singapore in 2026 costs between SGD 8,000 and SGD 18,000 per bathroom for a mid-range scope. A full hack and rebuild of a resale bathroom with aged infrastructure can reach SGD 20,000–28,000 per bathroom.

The range is wide because bathroom renovation involves more hidden variables than almost any other room. Three factors drive most of the cost difference:

•       Infrastructure age and condition — existing waterproofing integrity, pipe material, and substrate condition in walls and floor

•       Hack vs overlay decision — whether existing tiles are fully removed or new tiles are laid over the existing surface

•       Fixture specification — from a standard toilet and basic mixer to concealed cisterns, rainfall showers, and custom vanity carpentry

All cost estimates in this guide are calibrated to a standard HDB bathroom — approximately 3m x 2m, or roughly 65 sqft of combined floor and wall tile area. Master bathrooms in condos are typically larger; HDB common bathrooms are typically smaller.

Overlay vs full hack — the most important decision

Before pricing a bathroom renovation, decide whether to overlay existing tiles or fully hack and rebuild. This single decision has the largest impact on cost, timeline, and long-term outcome.

Option	What it involves	Cost impact	Best for
Tile overlay	New tiles laid directly over existing tiles. No hacking, no debris disposal, no new waterproofing.	Saves SGD 3,000–8,000 vs full hack	BTO flats within the 3-year wet area restriction; flats where existing tiles are structurally sound and waterproofing is intact
Full hack and rebuild	All existing tiles removed, waterproofing renewed, new substrate prepared before tiling.	Adds SGD 3,000–8,000 vs overlay	Resale flats with aged waterproofing; any bathroom with signs of seepage or hollow tiles; BTO flats after the 3-year restriction period

BTO 3-year rule: HDB prohibits hacking bathroom tiles in new BTO flats for 3 years from the block completion date — not your key collection date. Hacking within this period voids the HDB waterproofing warranty and can result in fines up to SGD 5,000. If your BTO is within this window, tile overlay is your only compliant option.

A practical note on tile overlay: overlaying adds 10–15mm to floor height, which affects door clearance and the transition to adjacent rooms. Check door clearance before committing — some bathrooms require a partial hack of the doorway threshold even with a full overlay approach.

Bathroom renovation costs 2026 — by scope

Scope	What is included	Per bathroom (before GST)
BTO overlay (basic refresh)	Overlay existing floor and wall tiles, replace toilet bowl, vanity tap and shower mixer, repaint ceiling	SGD 4,500–8,000
BTO full hack (mid-range)	Full tile hack, new waterproofing, retile floor and walls, replace all fixtures (toilet, vanity, shower screen, accessories)	SGD 10,000–16,000
BTO full hack (premium)	As above plus rainfall shower, freestanding vanity, frameless glass shower screen, heated towel rail	SGD 16,000–25,000
Resale basic refresh	Overlay tiles, replace toilet bowl and tap fittings only	SGD 5,000–9,000
Resale mid-range full hack	Full demolition, waterproofing renewal, retile, replace all fixtures, update plumbing and electrical	SGD 12,000–20,000
Resale premium full hack	As above plus premium fixtures, frameless shower, concealed cistern, feature wall tiles	SGD 20,000–30,000+

Add 9% GST to all figures. For a 2-bathroom HDB flat, budget the mid-range figures doubled — most homeowners renovate both bathrooms simultaneously to minimise disruption and share contractor mobilisation costs.

Line-by-line cost breakdown

1. Waterproofing — the most important and most skipped item

Waterproofing is the foundation of every bathroom renovation. In Singapore, bathroom seepage to the unit below is one of the most common and most expensive neighbour disputes — and the most common cause is failed or absent waterproofing.

Waterproofing type	Application	2026 cost per bathroom
PU membrane (standard)	Applied to floor and wet wall areas up to 300mm height. Minimum standard for any bathroom renovation.	SGD 800–1,500
PU membrane (full wall height)	Floor and full wall coverage — recommended for shower areas without an enclosure.	SGD 1,200–2,200
Crystalline waterproofing	Penetrating treatment that bonds with concrete. More durable than membrane alone. Recommended for older resale flats where substrate condition is uncertain.	SGD 1,500–3,000

Mandatory cure time: PU membrane requires a minimum 48-hour cure and a water ponding test before any tiling proceeds. A contractor who shortens or skips this is the single biggest source of seepage claims in Singapore. The cost of rectifying seepage to the unit below far exceeds the cost of doing waterproofing correctly.

2. Tiles — material and labour

Tile costs in Singapore are quoted per sqft and typically include both material supply and laying labour. A standard HDB bathroom has approximately 35–50 sqft of floor area and 120–160 sqft of wall area — roughly 65 sqft combined when averaged across typical bathroom dimensions.

Tile type	Best use in Singapore bathrooms	2026 cost (supply + lay per sqft)
Homogeneous tiles (standard)	Floor and wall — durable, non-porous, wide range. Most common choice in Singapore bathrooms.	SGD 8–25/sqft
Large format tiles (600x600mm+)	Fewer grout lines, visually spacious. Requires flatter substrate — add cost for floor levelling.	SGD 15–40/sqft
Natural stone (marble, slate)	Premium look but porous — requires annual sealing in Singapore humidity. High maintenance.	SGD 25–80/sqft
Mosaic tiles	Feature wall or shower niche accents. Labour-intensive to lay.	SGD 20–60/sqft
Anti-slip floor tiles	Mandatory for wet floor areas under HDB guidelines.	SGD 10–30/sqft

Full tiling of one standard HDB bathroom (3m x 2m) at mid-range specification: SGD 1,500–4,000 for materials, SGD 1,200–2,500 for laying labour.

3. Fixtures — toilet, vanity, shower

Fixture	Budget	Mid-range	Premium
Wall-hung toilet bowl	SGD 300–600	SGD 600–1,200	SGD 1,200–3,000
Floor-mounted toilet bowl	SGD 200–450	SGD 450–900	SGD 900–2,000
Concealed cistern (wall-hung only)	SGD 400–700	SGD 700–1,200	SGD 1,200–2,500
Vanity cabinet + basin	SGD 300–600	SGD 600–1,500	SGD 1,500–5,000
Shower mixer (exposed)	SGD 150–300	SGD 300–800	SGD 800–3,000
Rainfall shower head	SGD 100–250	SGD 250–600	SGD 600–2,000
Frameless shower screen	SGD 600–900	SGD 900–1,800	SGD 1,800–4,000
Bathroom accessories set	SGD 80–150	SGD 150–400	SGD 400–1,200

2026 material trend: sintered stone vanity tops are increasingly chosen over marble or solid surface alternatives in Singapore bathrooms. Sintered stone is fully non-porous — it does not absorb water, soap residue, or mould the way natural stone does. In Singapore's year-round humidity, this matters significantly. Price range: SGD 400–900 for a standard vanity top in sintered stone, versus SGD 300–700 for quartz and SGD 600–1,500+ for marble.

4. Plumbing and electrical

Item	When needed	2026 cost
Relocate toilet bowl position	If changing layout — requires new soil pipe routing	SGD 600–1,500
Replace inlet and outlet pipes	Mandatory in resale flats with iron pipes	SGD 800–2,000
Install water heater point	If adding instant or storage heater	SGD 200–400
Exhaust fan installation	Recommended for all Singapore bathrooms to control humidity and mould	SGD 150–350 (supply + install)
Waterproof downlights (IP65)	Required for wet zones by safety standards	SGD 80–200 per light

What to prioritise if budget is tight

•       Waterproofing — never cut this. Seepage to the unit below creates liability, neighbour disputes, and repair costs that dwarf the waterproofing savings.

•       Anti-slip floor tiles — non-negotiable for safety in wet areas

•       Toilet bowl — gets used daily; spend reasonably on a reliable brand

•       Shower mixer — a quality mixer lasts 10–15 years; budget versions fail within 3–5 years in Singapore water conditions

•       Sintered stone vanity top — worth specifying if the budget allows. Mould resistance is a genuine long-term benefit in Singapore humidity.

•       Rainfall shower and frameless screen — aspirational upgrades. Delay if budget is constrained.
