Complete Rental Curtain Makeover Guide: Blackout + Storage

The second apartment I rented had an east-facing bedroom. At 5:30 AM in the summer, sunlight would stream in like a spotlight and wake me right up. The landlord's curtains were a decade old, paper-thin, with maybe 10% blackout performance — purely decorative. I asked the landlord about replacing them, and he said, "Sure, but you have to put the old ones back when you move out."

I did the math — a new curtain set plus installation costs a few hundred bucks, and then I'd have to pay to take them down and reinstall the old ones when I move out. Way too expensive. So I figured out my own no-removal makeover plan. Cost me under $15, got 90%+ blackout, and solved a bedside storage problem along the way.

1. The Four Pain Points of Rental Curtains

Pain Point 1: Old curtains let light through. Most rental curtains are installed by the landlord on a budget, with the cheapest possible style, and the blackout performance is terrible. For developers who often stay up late and sleep in, getting woken by sunlight is a total nightmare.

Pain Point 2: Can't drill holes. Rental contracts usually explicitly ban drilling. Traditional curtain rod installation is a no-go. Even if the landlord allows it, patching the wall when you move out is a hassle.

Pain Point 3: Old curtains are ugly. Outdated patterns, yellowed colors, wrong length — they bring down your mood, but replacing them isn't worth it.

Pain Point 4: Curtain area is wasted space. Behind the curtains, above the curtain rod — these spaces can actually be used for storage, but most people never think about it.

2. Blackout Curtain Buying Tips

Blackout tiers:

• Tier 1 (90%+): Almost total darkness, for people who are extremely light-sensitive
• Tier 2 (70-90%): Noticeable darkening, meets most people's sleep needs
• Tier 3 (50-70%): Some blackout effect, but you'll still wake up to bright light in the morning

I went with Tier 1, coated style. Real-world test: at 8 AM when the sun's blazing outside, pulling the curtains makes the room feel like nighttime.

Material choice:

• Coated blackout fabric: Silver or black coating on the back, best blackout effect, moderate price. Downside: the coating can peel over time, be careful when washing.
• Triple-weave blackout fabric: Achieved through high-density weaving, no coating, more eco-friendly and durable. Downside: expensive, same blackout level costs twice as much as coated.
• Regular thick fabric: Relies on thickness for blackout, the effect is just okay, but breathable.

I'd recommend the coated style — best value, good enough for a few years of renting.

Sizing: Width should be 1.5-2x the window width, so when drawn there's some pleating — looks better and blocks light more thoroughly. Height is from the curtain rod to the floor, or whatever length you want. I'd suggest going long, not short — long can be hemmed, short can't be fixed.

Installation: For rentals, the first choice is tension rods or adhesive tracks, no drilling needed. Tension rods handle more weight, suitable for heavy blackout curtains. Adhesive tracks are easier to install, suitable for lightweight curtains.

3. No-Remove-Old-Curtain Makeover Plans

Plan 1: Blackout Liner (Most Recommended)

Add a blackout liner on the inside of the original curtain, keeping the outer decorative layer and adding an inner blackout layer.

Steps:

1. Measure the width and height of the original curtain
2. Buy a blackout liner of the same size (with hooks or rings)
3. Install with a tension rod on the inside of the original curtain rod, or hook directly onto the original curtain's rings
4. During the day, pull back the blackout liner to keep the outer decorative curtain visible. At night, draw both layers.

That's what I'm doing in my bedroom now. The outer layer is the landlord's beige curtain — not pretty but clean enough. The inner layer is a dark gray blackout liner I bought. From outside, it looks like the original curtain. From inside, the two layers stack up and the blackout effect is amazing.

Cost: blackout liner $7-12, tension rod $3-4.

Plan 2: Magnetic Blackout Curtain

For iron window frames or windows with magnetic strips installed. The blackout curtain has magnets on the edges, sticking directly to the frame for a tight, gap-free fit.

Pros: Super simple install, takes seconds. Tight fit, highest blackout rate. Cheap, $3-6 per panel.

Cons: Only works on iron window frames or requires extra magnetic strips. Each panel has to be peeled off and re-applied to open and close — annoying. Looks plain, like a car sunshade.

I used this in a company dorm. The frame was aluminum, so I installed magnetic strips myself, then stuck the blackout curtain on. The blackout effect was genuinely good, but peeling them off and re-applying them every morning and night — I gave up after two months.

Best for: Short-term rentals, people who don't want to deal with installation.

Plan 3: Full Blackout Window Film

Blackout film applied directly to the glass, like a screen protector.

Pros: Cheap, around $4 a roll. Zero space taken up. Doesn't affect the curtain's opening and closing.

Cons: Once applied, the window is permanently dark — no way to let light in during the day. Peeling it off can leave residue. Looks ugly from outside, like a black window.

I haven't tried this one — I think it's too ugly. But for a basement or a window with no view, it's worth considering.

4. The Curtain-as-Storage Plan

The curtain itself can also become a storage tool — a discovery I made during the makeover.

Sew pockets on the back of the curtain: Sew a few cloth pockets on the back of the blackout liner, for an eye mask, earplugs, AC remote, or a book to read before bed. I sewed three pockets — eye mask and earplugs on the left, remote in the middle, Kindle on the right. Reach for them before sleep, no need to turn on the light and hunt around.

Shelf above the curtain rod: The tension rod can do more than hold curtains — you can add a thin rod 20 cm above the curtain rod to hang light items. I installed a thin tension rod 20 cm above my bedroom curtain rod, and hung a few small plants. It uses the space and adds a bit of life.

Curtain tie-back with pockets: Buy curtain tie-backs with pockets — they store small items when tying back the curtain. I got tie-backs with small inner pockets, perfect for sachets or a small comb.

Storage under the windowsill: If the curtain goes all the way to the floor, the space under the windowsill is usually hidden. You can put some not-so-pretty storage bins there. I have two storage bins under my windowsill with out-of-season clothes, and the curtain hides them completely.

5. Three Popular Blackout Curtains Reviewed

1. IKEA MAJGULL

Price: around $18 per pair

IKEA's classic blackout curtain, coated style, multiple colors available. I bought a pair in dark blue, with about 85% blackout rate. Not total darkness, but the room is noticeably darker.

Pros: Lots of color options, plays well with other IKEA products. Standard sizes, no need to customize. Cons: Not top-tier blackout, may not be enough for the extremely light-sensitive. The coating can flake a little on the back after extended use.

Best for: Users who want both blackout and good looks.

2. Custom Blackout Liner (Taobao)

Price: around $5-8 per panel

That's what I'm using in my current bedroom. Custom-sized to the window, silver coating on the back, 95%+ blackout rate.

Pros: Cheap, great blackout, custom sizing. Cons: Plain looking, doesn't look great on its own, needs to be paired with an outer curtain. The coating has a slight smell when new, you need to air it out for a few days.

Best for: Budget-conscious users who want the best blackout possible.

3. MUJI Blackout Curtain

Price: around $40

Triple-weave, no coating, relies on high-density fabric for blackout. My girlfriend bought one, beige, the texture is genuinely good, feels like thick cotton.

Pros: Eco-friendly, no coating, premium texture, breathable. Cons: Expensive, same size costs three times the coated version. Blackout rate is about 80%, not as complete as coated.

Best for: Quality-focused users with healthy budgets, and people who have concerns about coatings.

6. Installation Tips

Tension rod installation: Measure the inside width of the window frame, buy a tension rod with a matching range. Set the rod 2-3 cm wider than the frame, and when you tighten, give it some real force — only when you hear the locking click is it truly secured. My first rod wasn't tight enough and fell in the middle of the night. Scared me half to death.

Adhesive track installation: The window frame surface must be clean and dry, wipe it down with an alcohol pad. Press the adhesive track for 30 seconds after applying, and let it sit for 24 hours before hanging the curtain. Don't rush it. If you hang heavy stuff before the adhesive has cured, it will definitely fall.

Hook spacing: Rings or hooks should be evenly spaced, generally one every 10-15 cm. If the spacing is too wide, the curtain won't hang evenly and will sag in the middle, letting light through.

Floor length: The curtain bottom can slightly brush the floor by 2-3 cm, so the bottom doesn't let light through. But don't make it too long — it'll collect dirt when sweeping, and you can trip on it.

7. One Curtain, Multiple Uses — Summary

My final plan: Keep the landlord's curtain on the outside (saves money, avoids disputes), add a custom blackout liner inside (for blackout and storage pockets), and use a tension rod (no drilling, can be taken with me). Total cost under $15, blackout rate 90%+, plus three bonus storage pockets.

I don't get woken up by sunlight anymore. On weekends I sleep until I naturally wake up. At night I pull the curtains, the room is pitch black, and combined with white noise, I fall asleep way faster.

For developers who need high-quality sleep, a blackout curtain has an incredible ROI. $15 for an extra hour of sleep every day — totally worth it.
