Window treatments are one of the last line items in a flat renovation, and one of the easiest to overpay on. In 2026, a budget HDB BTO curtain package covers a whole flat from around S$650 to S$930 depending on flat size, while going custom with day-and-night curtains, blinds and motorised tracks across the same flat can run S$3,000 to S$9,000. The gap is huge because curtains and blinds are sold by the metre, by the window and by fabric grade, so the same window can cost S$120 or S$900 depending on what you pick. This guide breaks down the real 2026 prices in Singapore, what drives them, which option fits which room, and how to set a budget that covers the whole flat without a nasty surprise at the final invoice.
For a 4-room HDB flat, expect to spend roughly S$650 to S$730 on a basic BTO curtain package, S$1,500 to S$3,500 if you fit roller blinds throughout, S$3,000 to S$5,500 for mid-range day-and-night curtains, and S$5,500 to S$9,000 for premium blackout fabrics with motorisation-ready tracks. The cheapest end is a fixed retailer package; the dearer end is custom work measured and made to your exact windows.
Per window, the 2026 ranges are clear enough to plan around. A plain day curtain starts from about S$120, a day-and-night curtain set runs S$280 to S$750, a blackout curtain is S$350 to S$900, and a roller blind is S$180 to S$450. Adding a motorised track with remote adds S$350 to S$900 per window on top.
If you are furnishing a new flat, treat curtains as part of the renovation budget, not an afterthought. They typically land in the last 5 to 10 percent of a renovation spend, and the choice between a package and custom is where most of the money decision sits.
The cheapest route for a new HDB flat is a fixed BTO curtain package. These are pre-priced bundles that cover every window in the flat, including the fabric, sewing, tracks and installation, for one flat fee. Retailers compete hard on these because they want the whole-flat order, so the per-window cost works out lower than buying piece by piece.
Across the market in 2026, BTO package prices sit roughly as below. They usually cover night curtains (the opaque layer) for all rooms; adding sheer day curtains on a second track costs extra, often S$100 to S$200 per room.
| Flat type | Budget package | Night curtains (made-to-measure) | Day-and-night curtains |
|---|---|---|---|
| 2-room | S$420 to S$500 | From S$750 | From S$950 |
| 3-room | S$520 to S$630 | From S$950 | From S$1,200 |
| 4-room | S$650 to S$730 | From S$1,100 | From S$1,500 |
| 5-room | S$750 to S$930 | From S$1,400 | From S$1,900 |
Curtain fabric is graded by how much light it blocks, and that grade is the single biggest driver of price after window size. Knowing the four common types stops you paying for blackout where a dim-out would do.
Day curtains are the sheer, semi-transparent layer. They soften daylight and give daytime privacy without making a room dark, and they are the cheapest fabric, from about S$2.00 per square foot. Dim-out, or night, curtains block roughly 85 to 95 percent of light and start from around S$3.00 per square foot. Blackout fabric blocks about 99 percent of light for a fully dark room and runs from about S$5.00 per square foot. A day-and-night set is two layers on one window, a sheer in front and an opaque behind on a second track, so you slide whichever you need.
Bedrooms facing the morning sun are where blackout pays off, especially for shift workers or light sleepers. Living rooms usually do well on a day-and-night set: sheers by day, dim-out for evening privacy and glare control on the TV. A study or kitchen often only needs a single dim-out layer.
Two curtains in the same fabric can cost different amounts because of how the top is pleated. The pleat sets how much fabric is gathered, and more fabric per metre of window means a fuller look and a higher price. This is the line item buyers rarely ask about and suppliers rarely volunteer, so it pays to know what you are choosing before you sign.
Pinch and goblet pleats use the most fabric, around two to two-and-a-half times the track width, for a tailored, formal drape. Pencil pleat sits in the middle. Eyelet (grommet) curtains thread onto a rod through metal rings for a clean modern look and use less fabric, which usually makes them the cheapest finished style. Ripple fold, the soft S-wave you see in showrooms, needs a special track and carrier and costs more than it looks. If a quote seems high for a plain fabric, the pleat is often why.
Blinds suit windows where curtains are awkward, like kitchens, study nooks, balconies and small windows, and they give a cleaner look. They are priced by type and by the same fabric grades, so a light-filtering roller costs less than a blackout one of the same size.
Roller blinds are the workhorse: a single fabric sheet on a tube, simple and cheap. Zebra or Korean combi blinds layer alternating sheer and solid bands so you adjust light like a day-and-night curtain in one unit. Venetian blinds use horizontal slats in aluminium, PVC or wood. Roman blinds fold up in soft fabric pleats for a more dressed look. The table shows 2026 per-window ranges; final price depends on window size, fabric grade and whether you motorise.
| Blind type | Typical per window | Light control | Best for |
|---|---|---|---|
| Roller blind | S$180 to S$450 | Light-filter, dim-out or blackout fabric | Kitchens, studies, small windows |
| Zebra / Korean combi | About S$5.90 to S$8.90 psf incl. install | Adjustable via sheer-solid bands | Living rooms wanting curtain-like control |
| Venetian (aluminium/PVC/wood) | Around S$300 per window | Tilt slats for precise light angle | Bathrooms, wet areas, modern look |
| Roman blind | Mid-range, varies by fabric | Depends on fabric grade | Bedrooms, a softer dressed look |
Indoor coverings get all the attention, but the balcony and service yard are where many Singapore households actually spend on window treatments. Afternoon sun, wind-driven rain and the haze season all push owners toward outdoor blinds, and these are priced and built differently from indoor ones.
Outdoor zip blinds run the fabric edges inside a side channel so wind cannot blow them around, which is why they suit high-floor and exposed balconies. They come in mesh-style sunscreen fabric that cuts glare and heat while keeping the view, or in solid PVC for full rain shielding on a service yard. Because they handle weather and use heavier hardware, outdoor zip blinds cost more than an indoor roller of the same size, and motorised versions are common since reaching an outdoor blind by hand is awkward.
Curtains and blinds sit in your home for years, and young children and pets touch and chew them, so fabric safety is worth a question at the showroom. The recognised mark to ask for is OEKO-TEX STANDARD 100, an independent label that tests textiles for harmful substances from the yarn to the finished product. Every thread, button and accessory in a certified article is tested against a list of over 1,000 harmful substances, and stricter limits apply to items with more skin contact.
Certification is not free for the maker, so certified fabric usually sits a notch above the cheapest bargain-bin rolls. For a guest room you rarely sit in, untested budget fabric is a fair trade-off. For a nursery, a child's bedroom or a home with pets, paying the small premium for a certified fabric is the kind of spend that is hard to regret.
Window treatments are a multi-year purchase, so the running cost belongs in the decision, not just the sticker price. Curtains hold dust and, near a kitchen, cooking grease, and benefit from a wash or professional clean every three to six months depending on how exposed they are. Blinds are easier; a wipe with a cloth or a quick vacuum every month or so keeps them clear, with a deeper clean now and then.
Fabric choice changes upkeep too. Light sheers show less dust than dark dim-out, and west-facing dim-out and blackout fabrics fade faster without UV treatment, which can mean replacing fabric in a few years rather than ten. Professional curtain cleaning runs about S$15 to S$30 per panel, so a flat's worth of panels adds up over a decade. Easy-care fabrics and removable, machine-washable panels lower this lifetime cost more than most buyers expect.
Motorised tracks and blinds are the fastest way to push a curtain budget up. A motorised curtain track with remote adds S$350 to S$900 per window over a manual one. For blinds, a branded motor from a maker like Somfy or Hunter Douglas can be S$500 to S$1,200 or more per window.
The money trap here is cheap motors. Unbranded motors often fail soon after the one-year warranty ends, so a low quote can mean replacing the mechanism within a couple of years. A branded motor typically lasts 8 to 12 years. If you are motorising, spend on the motor and save on the fabric rather than the other way round, and motorise only the windows you would otherwise struggle to reach, like a high living-room feature window, rather than the whole flat.
Smart-home integration (voice control, app scheduling, sun sensors) usually comes built into the branded motor and adds little hardware cost once the motor is in, but check it works with whatever hub you already use before committing.
The biggest single choice is whether to take a fixed package or go custom. A budget BTO package for a 4-room flat at S$650 to S$730 is hard to beat on price, and it covers every standard window in one go. The trade-offs are limited fabric choice, standard pleating, a height cap around 2.6m, and tracks that may not be motorisation-ready.
Custom work, measured and made to your windows, lets you mix fabric grades by room, run day-and-night layers, fit motorised tracks and handle odd window sizes. That flexibility is why a custom 4-room fit-out reaches S$3,000 to S$5,500 mid-range and S$5,500 to S$9,000 premium. For a 3-bedroom condo, mid-range custom curtains and blinds run roughly S$10,000 to S$22,000, and landed homes can be S$15,000 to S$60,000 or more.
A sensible middle path for most flats is a hybrid: take a package for the bedrooms and secondary windows where standard night curtains are fine, then spend custom money only on the living room (a day-and-night set) and the master bedroom (blackout). That keeps the bulk of the flat cheap and puts the budget where it changes daily life. Slot the figure into your renovation plan early using a personal budget calculator so curtains are not the line that blows the ceiling.
Price aside, the supplier you choose decides whether the curtains hang straight, arrive on time and get fixed if something is off. The good ones offer an on-site survey rather than asking you to measure, give an itemised quote, and put a workmanship warranty in writing. The cheap ones quote off a phone photo, fold everything into one number, and go quiet after installation.
Get two or three quotes for any custom work, because the same windows can vary 30 to 40 percent between suppliers, and ask each to break the quote into fabric, track, pleat and installation so you are comparing like with like. A reputable shop will offer a mock-up or fabric samples to take home, since fabric reads very differently in showroom light versus your own. Treat curtains as one line in the wider renovation cost picture rather than a standalone splurge, and the supplier choice gets easier.
A few line items catch first-time buyers. Curtain height above the standard 2.6m drop adds a surcharge, and bay or arched windows are quoted separately. Day curtains added to a night-only package cost S$100 to S$200 per room. Installation can be itemised separately by some retailers: about S$50 to S$150 per window for curtains, S$80 to S$200 for roller blinds, and S$100 to S$300 for blackout setups, though most package prices already fold this in.
On GST, read the quote carefully. Many BTO packages advertise an all-in price with no extra GST at the till; some smaller curtain businesses sit below the S$1 million annual turnover threshold and are not GST-registered, so they genuinely cannot charge it. A larger retailer that is GST-registered must add 9 percent, the rate in force since 1 January 2024 and unchanged in 2026. The point that matters for your budget is whether the figure you were quoted is final or has 9 percent to come, so ask. If GST applies on a S$5,000 custom job, that is S$450 you need to have planned for. See the GST glossary entry if the mechanics are unfamiliar.
Ongoing cost is small but real. Professional curtain cleaning runs about S$15 to S$30 per panel, and blackout and dim-out fabrics in west-facing windows fade faster without UV treatment, which can mean replacement in a few years rather than ten. Paying a little more for UV-treated fabric on sun-blasted windows is usually cheaper over time.
Set the curtain budget against the flat, not the showroom. A clean starting frame for an HDB flat is a package figure for the bedrooms plus a custom allowance for one or two living spaces. For a 4-room flat that might be a S$700 package plus S$800 to S$1,500 of custom living-room and master-bedroom work, landing you around S$1,500 to S$2,200 all-in, well below a full custom fit-out and far more livable than a bare package.
The savings levers are straightforward. Buy as a whole-flat package rather than window by window. Match fabric grade to the room instead of putting blackout everywhere. Measure twice, because made-to-measure mistakes are on you, and confirm whether GST is in the price before signing. Get two or three quotes for any custom work, since the same windows can vary 30 to 40 percent between suppliers. If you are renovating a resale flat, reuse existing tracks where they are sound and only replace fabric.
Money saved on curtains is money that can do more elsewhere. If furnishing a new flat has stretched your budget, redirecting a few hundred dollars saved on window treatments into an emergency fund or even a Singapore Savings Bond does more for you than premium fabric in a guest room. Our HDB BTO guide covers the larger renovation and grant picture if this is your first flat, and the compound interest calculator shows what redirected savings grow into over time.
A budget BTO curtain package for a 4-room flat runs about S$650 to S$730 and covers all standard windows with night curtains, tracks and installation. Going custom raises it to roughly S$1,500 to S$3,500 with roller blinds, S$3,000 to S$5,500 for mid-range day-and-night curtains, and S$5,500 to S$9,000 for premium blackout with motorisation-ready tracks.
For covering a whole flat, a fixed curtain package is usually the cheapest route, from about S$650 for a 4-room. Per window, a plain roller blind at S$180 to S$450 can be cheaper than a custom day-and-night curtain set at S$280 to S$750. Blinds suit small or awkward windows; curtains usually give better full darkness and value across a whole flat.
Dim-out fabric blocks roughly 85 to 95 percent of light and starts from about S$3.00 per square foot, good for living rooms and studies. Blackout fabric blocks about 99 percent of light for a fully dark room and starts from about S$5.00 per square foot, best for bedrooms. Day curtains, the sheer layer, are cheapest from about S$2.00 per square foot.
It depends on the seller. Many BTO packages advertise a final all-in price with no extra GST, and small curtain businesses below the S$1 million turnover threshold are not GST-registered so cannot charge it. A larger GST-registered retailer must add 9 percent, the rate since 1 January 2024. Always confirm whether the quoted figure is final before signing.
A motorised curtain track with remote adds S$350 to S$900 per window over a manual one. For blinds, a branded motor from a maker like Somfy or Hunter Douglas can be S$500 to S$1,200 or more per window. Cheap unbranded motors often fail just after the one-year warranty, so spend on a branded motor and motorise only the windows worth automating.
Zebra or Korean combi blinds layer alternating sheer and solid fabric bands so you adjust light like a day-and-night curtain in a single unit. In Singapore they typically cost about S$5.90 to S$8.90 per square foot including installation, with BTO package versions available. They suit living rooms wanting flexible light control where a double curtain track would not fit.
A package is cheaper and faster but limits fabric choice and caps height around 2.6m. Custom costs several times more but lets you mix fabric grades, run day-and-night layers and motorise. For most flats a hybrid works best: take a package for bedrooms and secondary windows, then spend custom money only on the living room and master bedroom.
Usually the pleat. Pinch and goblet pleats gather about two to two-and-a-half times the track width in fabric for a full drape, so they cost more than a pencil pleat, while eyelet (grommet) curtains use the least fabric and are normally the cheapest finished style. Ripple fold needs a special track and carrier, which adds hardware cost. If a quote looks high for a plain fabric, the pleat is often the reason.
Outdoor zip blinds run the fabric edges inside side channels so wind cannot blow them around, which suits exposed and high-floor balconies. Choose sunscreen mesh to cut glare and heat while keeping the view, or solid PVC for full rain shielding on a service yard. They cost more than an indoor roller of the same size because of the weatherproof build, and are often motorised since reaching them by hand is awkward. Check your HDB or condo rules on external fixtures first.
Curtains benefit from a wash or professional clean roughly every three to six months, more often in kitchens or near busy roads where they collect grease and dust. Blinds are easier: a wipe with a cloth or a quick vacuum about monthly keeps them clear, with a deeper clean now and then. Professional curtain cleaning runs about S$15 to S$30 per panel, so removable, machine-washable panels lower the lifetime cost.
Ask for fabric carrying the OEKO-TEX STANDARD 100 label, an independent certification that tests textiles for harmful substances from the yarn to the finished product, with every thread and accessory checked against a list of over 1,000 substances and stricter limits for items with more skin contact. Certified fabric costs a little more than the cheapest rolls, which is worth it for a nursery, child's room or a home with pets.
