HDB Curtain Prices 2026: 3-Room vs 4-Room vs 5-Room Full Cost Breakdown

Last updated: August 2026 — For HDB and BTO flats in Singapore only. All prices in SGD, including tracks and installation.

“How much do curtains cost for an HDB 3-room, 4-room or 5-room flat?” is the question we hear most from BTO owners before key collection. The honest answer: it is not the number of rooms that sets your price — it is the number and size of your windows, plus the fabric you pick. A 3-room with a big living room bay window can cost more than a 4-room with small bedroom windows.

In this guide we break down realistic 2026 prices for every HDB flat type, show you exactly where the money goes, and give you a budget-smart mix that saves hundreds without looking cheap. Every figure below comes from real HDB and BTO quotes — condos not included.

How HDB Curtain Pricing Actually Works

Curtain quotes in Singapore are almost always calculated per window, not per flat. Each window is priced on width, height, fabric grade, and track type, then installation is added on top. So the first step is counting windows.

HDB Flat Type	Typical Windows	Typical Layout
3-room	5–7	Living + kitchen + 2 bedrooms
4-room	7–9	Living + kitchen + 3 bedrooms
5-room	9–11	Living + kitchen + 3 bedrooms + utility/study

A typical 3-room has around 5–7 windows, a 4-room around 7–9, and a 5-room around 9–11 once you count living room, kitchen, service yard and bedrooms. Multiply that by the price per window and you get your ballpark — which is why the tables below matter more than any flat-wide estimate.

2026 Price Comparison: Curtains, Blinds, or Mixed

Option A: Full curtains on every window (blackout)

Flat Type	Typical Cost	Per-Window Range
3-room HDB	$1,050–$1,400	$150–$230
4-room HDB	$1,300–$1,750	$150–$230
5-room HDB	$1,550–$2,100	$150–$230

Full blackout everywhere is the most expensive option. It is great for bedrooms, but in the living room and kitchen it is usually overkill — most HDB families only need light control there, not total darkness.

Option B: Blinds on every window (dim-out rollers)

Flat Type	Typical Cost	Per-Window Range
3-room HDB	$720–$980	$80–$130
4-room HDB	$900–$1,220	$80–$130
5-room HDB	$1,080–$1,450	$80–$130

Roller blinds are the budget champion: roughly 25–35% cheaper than full curtains. Dim-out rollers suit bedrooms, kitchens and service yards. For living rooms, zebra blinds ($110–$180) give a more finished look for a small premium.

Option C: The budget-smart mix (our recommendation)

Flat Type	Setup	Typical Cost
3-room HDB	Living day curtains + 2 bedrooms blackout + kitchen roller	$830–$1,100
4-room HDB	Living day curtains + 3 bedrooms blackout + kitchen roller	$1,030–$1,380
5-room HDB	Living day curtains + 3 bedrooms blackout + kitchen/utility rollers	$1,200–$1,600

The mixed approach keeps blackout fabric where you sleep, lighter (cheaper) fabric where you live, and cheap rollers in utility spaces. For a 4-room it lands around $1,030–$1,380 — roughly $300–$400 less than all-blackout curtains, with no visible compromise.

Where the Money Goes: 5 Hidden Cost Drivers

• Bay windows. HDB bay windows are 500–600 mm deep. Curtains need a wider track and more fabric to cover them properly — budget $60–$120 extra per bay window.
• Full-height living windows. Newer BTOs have tall living room windows. More fabric height = higher price; a floor-to-ceiling living window can cost 1.5× a standard bedroom window.
• Track type. PVC tracks are cheapest; aluminium and motorised tracks add $50–$250 per window. Motorise only the hard-to-reach ones.
• Fabric grade. Dim-out ($80+) → blackout ($150+) → thermal blackout ($180+) → designer/linen blends ($250+). Pick grade by room function, not by habit.
• Installation and delivery. Most HDB quotes bundle this in, but check — some shops charge $30–$80 extra per trip, and HDB installation windows (weekdays) can carry a surcharge.

How to Cut Your HDB Curtain Budget by 30%

• Blackout only the bedrooms. The living room, kitchen and service yard only need day curtains or rollers — this alone can save $300–$500 on a 4-room.
• Count every window before quoting. Bring your floor plan and window list to every shop so quotes are comparable apples-to-apples.
• Ask for HDB/BTO packages. Most Singapore curtain shops (including Shade Degree) offer flat-type packages — a 4-room package is always cheaper than buying window-by-window.
• Skip sheers behind curtains. Modern blackout and dim-out fabrics do the job alone; the extra sheer layer adds $100+ per flat.
• Book measurement before key collection. A free measurement session locks in today's prices and lets you plan before renovation starts.

FAQs: HDB Curtain Prices by Flat Type

Does a 3-room cost half of a 5-room?

No. A 5-room has roughly 40–60% more windows than a 3-room, so expect roughly 30–50% more — not double. Flat size matters less than window count and fabric choices.

How much should a 4-room BTO set aside for curtains?

Budget $1,000–$1,400 for a sensible mix (blackout bedrooms + day curtains living + rollers kitchen). All-blackout-everywhere runs $1,300–$1,750; all-blinds runs $900–$1,220.

Are bay windows more expensive to curtain?

Yes, usually $60–$120 extra per bay window for the wider track and extra fabric. It is one of the most common under-budgeted items in BTO renovation plans.

Can I curtain only the bedrooms first?

Absolutely. Many BTO owners start with bedroom blackout curtains and add living room treatments after moving in. Getting measured once and staging the work is the smart way to spread the cost.
