Aluminium Door Price Singapore (2026): HDB & Condo Guide

Why Aluminium Door Prices in Singapore Vary So Widely

The Common Expectation vs Reality

If you're like most Singaporean renovators, you think: "It's just a door, how much can it cost?" One contractor call reveals the reality. A toilet door might pull quotes from $400 to $1,200. A sliding kitchen door: $800 to $2,000. Same opening, wildly different prices.

Renovation cases show homeowners comparing three quotations seeing variations of $300–$500 per door. That's not greed, it's specification differences you haven't discussed yet.

What Most Homeowners Don't Realise

Door type dramatically affects cost. A hinged toilet door differs fundamentally from a sliding kitchen door or bi-fold partition. Each demands different hardware, frame strength, and installation approaches.

Glass, hardware, and frame thickness matter more than size. A standard HDB toilet opening might be identical for ten flats, yet quotes range $500–$1,200 based on glass thickness (3mm vs 5mm), roller grade, and frame reinforcement.

Installation complexity varies by property type. HDB flats face space constraints and renovation guidelines. Condos require MCST approval, noise restrictions, and management coordination that add time and cost.

Who This Guide Is Designed For

This guide serves HDB homeowners upgrading toilet or kitchen doors, condo owners replacing balcony or partition doors, and renovators comparing quotations before committing. If you're about to request door quotes and want to understand what's actually being priced, this is for you.

Understanding Aluminium Door Pricing Basics

What Does an Aluminium Door Price Typically Include?

A credible quotation should cover: aluminium frame fabrication, glass panel or infill material, hinges/rollers/tracks/locking systems, installation labour, and removal and disposal of old doors. When quotes vary significantly, clarify what's bundled and what's extra.

Main Types of Aluminium Doors & Their Cost Differences

Hinged (Swing) Doors: Common for toilets and bedrooms. Straightforward operation, moderate pricing. $400–$800 per door (standard sizing).

Sliding Doors: Popular for kitchens and balconies. Track and roller quality significantly affects cost. $600–$1,500 per door.

Bi-Fold Doors: Space-saving for compact HDB layouts. More hardware components = higher tier. $1,000–$2,000+ per door.

Glass Doors: Modern interior partitions. Pricing depends on glass thickness and type. $500–$1,200 per door.

What Actually Affects Aluminium Door Price in Singapore (2026)

1. Door Dimensions & Configuration

Standard single-leaf doors follow baseline pricing. Double-leaf configurations multiply frame and hardware costs. Full-height glass doors (floor-to-ceiling) require structural analysis and reinforcement. Custom sizing for non-standard HDB openings demands fabrication time and specialized work.

2. Glass Specification

Clear vs Frosted Glass:

• Clear: Baseline. Standard for kitchens and balconies.
• Frosted: +10–15% cost. Privacy-focused for toilet and bedroom doors.

Tempered vs Laminated Safety Glass:

• Tempered: Heat-treated for strength, standard in HDB approvals (5–10% premium).
• Laminated: Two panes bonded with interlayer, +20–30% cost. Preferred for high-traffic areas and safety compliance.

Thicker Glass for Durability:

• 3mm: Baseline.
• 5mm: +15–20% cost. Better acoustic properties and durability.
• 6mm+: +25–35% cost. Maximum strength, rarely necessary except in commercial settings.

PRO-TIP: For HDB toilet doors in humid environments (especially low-floor flats), skip aesthetics and invest in 5mm tempered glass. The extra thickness resists condensation warping and lasts 2–3 years longer than thin profiles. Your door won't fog up or warp mid-renovation.

3. Frame Profile & Thickness

Standard residential frames (1.2–1.4mm) suit typical HDB and condo doors. Reinforced profiles (1.6–2.0mm) resist warping in high-humidity areas and high-traffic kitchens, justifying 10–15% cost premiums for durability-conscious buyers.

4. Hardware & Track Systems

Roller quality for sliding doors: Commercial-grade rollers cost $100–$200 more but last 10+ years. Budget rollers jam within 18 months.

Stainless steel hinges: Resist corrosion in humid bathrooms, $50–$100 extra.

Soft-close mechanisms: Hydraulic dampening, $80–$150 per door. Valuable for kitchens with foot traffic.

Multi-point locking: More secure, +$60–$120.

5. Finishes & Powder Coating

Standard white or black is baseline. Custom colours add $40–$100 per door. Quality matters, cheap finishes discolour within 2–3 years in Singapore's humidity.

6. Installation Complexity

HDB Flats: Space constraints require careful measurement. HDB renovation guidelines require proper anchoring and sealing.

Condominiums: MCST approval may be required. Noise and timing restrictions apply (no work before 9 AM weekends).

7. Compliance & Safety Standards

Fire-rated doors apply only if separating stairwells (rarely residential). HDB permits require proper anchoring. Documentation is essential for resale.

Estimated Aluminium Door Price Ranges in Singapore (2026)

General Market Price Guide (Per Door)

Pricing varies significantly based on glass type (3mm vs 5mm), hardware grade, and frame thickness.

Estimated Full-Unit Budget Ranges

3-room HDB flat (toilet + kitchen doors): $2,000–$4,500 4–5 room HDB flat (toilet + kitchen + bedroom doors): $4,000–$8,000 Condominium (balcony + interior doors): $3,000–$7,000

Why Extremely Cheap Quotes Can Be Problematic

Quotes below $300 per door usually signal issues: thin aluminium warps within 3–4 years in humid HDB bathrooms, low-grade rollers jam within 18 months, poor sealing causes water leakage (especially toilet doors), and vague warranties offer no protection when failures occur.

Common Mistakes That Increase Door Replacement Costs

Choosing Based Solely on Lowest Price: Cheap doors requiring hardware replacement within 2 years eliminate any savings. The "budget" option becomes expensive fast.

Overlooking Humidity & Water Exposure: Toilet doors in poorly ventilated bathrooms face daily moisture. Kitchen steam and grease accelerate finish degradation. Frame thickness and glass quality directly impact longevity.

Ignoring Track & Roller Quality for Sliding Doors: Frequent jamming, misalignment, and maintenance calls frustrate daily use. Commercial-grade rollers cost more upfront but prevent years of irritation.

Not Clarifying Scope of Work: Does the quote include removal of your old door? Are sealants, finishing, and paint touch-ups included? Hidden costs emerge during installation when these aren't pre-agreed.

How to Compare Aluminium Door Quotations Properly

What a Transparent Quote Should Clearly State

Don't sign until you see these 5 things in writing:

1. Frame thickness (minimum 1.2mm for residential; less is a red flag)
2. Glass type & thickness (e.g., "clear 5mm tempered" or "frosted 4mm)
3. Hardware specifications (e.g., "stainless steel hinges" or "commercial-grade rollers")
4. Installation scope (removal, sealants, finishing, paint touch-ups)
5. Warranty duration (frame vs hardware separately, and what voids coverage)

Key Questions to Ask Before Confirming

• What grade of aluminium is used? (6063-T5 is standard; ask to confirm)
• What type of rollers or hinges are installed? (Brand names, not generic labels)
• Is there post-installation servicing if the door sticks or roller maintenance is needed?
• What voids the warranty? (Humidity damage? Installation mistakes by others?)
• Can you provide references from similar HDB/condo projects completed in the past year?

Evaluating Contractor Credibility

Verify HDB-registered status if required. Review past installation projects in similar flats or buildings. Look for clear documentation, transparent invoicing, and willingness to explain specification choices. Established providers offer accountability that bargain contractors cannot guarantee.

Making a Smart, Cost-Effective Decision

When Repair Is More Practical Than Replacement

Minor roller replacement on sliding doors costs $100–$200 and restores functionality. Hinge adjustment or seal replacement addresses 80% of door complaints at a fraction of replacement cost.

When Full Replacement Is the Safer Option

Structural warping (door won't close properly), severe corrosion (especially in toilet areas), and persistent leakage or misalignment all signal replacement necessity. Repairs provide only temporary relief.

Budgeting Strategically for Long-Term Durability

Prioritise hardware quality over aesthetics. Allocate more budget for high-use doors (kitchen, toilet) where daily wear is heaviest. Avoid unnecessary finishes (woodgrain, custom colours) unless they solve a functional problem. A $1,200 durable kitchen door lasting 12+ years costs less per year than a $600 budget door lasting 4 years.

PRO-TIP: For HDB flats, request quotes for your specific unit type (e.g., "Kallang 4-room, 1980s block"). Contractors familiar with your building type estimate more accurately and understand local installation quirks, tight spaces, concrete thickness, electrical conduit routing.

Conclusion

Aluminium door prices in Singapore vary based on door type (hinged vs sliding vs bi-fold), glass specification (thickness and safety grade), frame durability, hardware quality, and installation complexity unique to HDB or condo settings.

Extremely low quotations typically reflect compromises in material durability or workmanship that create costly maintenance issues within 2–3 years.

Comparing quotations based on explicit specifications, not just headline prices, protects long-term value and prevents regret. A well-informed homeowner can now evaluate aluminium door costs confidently and make durable, cost-effective decisions in 2026.
