Walk into any high-end boutique hotel and you might notice something odd about the window treatments. They look heavy. They look expensive. But if you get close enough to touch them—don't actually do that, it's weird—you might realize they aren't traditional velvet or silk. They are often heavy-gauge, textured polyester or treated cotton.
Basically, they’re shower curtains.
Using shower curtains as curtains for your windows isn't just a "broke college student" move anymore. It’s a legitimate design choice used by professionals to solve specific problems like moisture, light filtration, and the absolute insanity of custom drapery prices. If you've ever priced out custom floor-to-ceiling linen panels, you know they can easily run $500 a window. A high-quality fabric shower curtain? It’s $25 at Target or West Elm.
Why the Math Favors the Bathroom Aisle
Standard windows are usually around 60 to 84 inches tall. Standard shower curtains are almost universally 72 by 72 inches. This square dimension is the "secret sauce" for standard apartment windows. Most window curtains are sold in narrow panels (42 or 50 inches wide), forcing you to buy two or even four panels to get that lush, gathered look.
A single shower curtain is already six feet wide.
One panel covers the whole window. It's efficient. Honestly, the textile industry has been overcharging for "window" fabric for decades when the "bath" fabric is often more durable. Brands like Hookless or Madison Park produce weighted, hotel-style curtains that have more structural integrity than the flimsy sheer panels you find in the window treatment aisle.
The Moisture Factor Nobody Mentions
Think about your kitchen or your laundry room. Maybe you have a window right above the sink where you’re constantly splashing suds. Or maybe you live in a basement apartment where the walls feel a bit damp in the summer.
Traditional drapes hate humidity. They grow mold. They get that weird "musty basement" smell that no amount of Febreze can fix.
But shower curtains as curtains are literally engineered to live in a swamp. Most are treated with antimicrobial coatings or are made from synthetic fibers like PEVA or heavy-duty polyester that repel water. If you put a fabric shower curtain in a kitchen window, you don't have to worry about steam from a boiling pot of pasta ruining the fabric. You just throw it in the wash on a cold cycle once a month. It’s indestructible.
How to Make It Look "High End" (and Not Like a Dorm)
You can't just slap a plastic liner with little cartoon ducks on a tension rod and call it a day. That’s how you lose your security deposit or, worse, your dignity.
To pull this off, you need to focus on the "header"—that's the top part with the holes. Most shower curtains have metal grommets or buttonholes. If you use standard plastic shower rings, it will look like a bathroom. Instead, use curtain clip rings. These are metal rings with a small alligator clip at the bottom. You clip them onto the top edge of the curtain, hiding the holes entirely. It gives the fabric a pleated, professional drape.
Texture is your best friend here. Avoid anything shiny or "plasticky." Look for:
- Waffle Weave: This adds physical depth and mimics the look of high-end spa robes.
- Slub Linen Blends: These have those little "imperfections" in the thread that make them look like expensive organic cotton.
- Seersucker: Great for a breezy, coastal vibe in a bedroom.
The weight matters, too. A light curtain will blow around every time the AC kicks on. If the curtain doesn't have weights in the bottom hem, you can actually buy small lead weights or even heavy washers at a hardware store and sew them into the corners. This makes the fabric hang straight and "puddle" slightly on the floor, which is a classic interior design trick for making a room feel taller.
The Problem With Length
The biggest hurdle is the height. Since most shower curtains are 72 inches long, they might hang a bit short if your curtain rod is mounted high near the ceiling. In the design world, curtains that stop a few inches above the floor are called "high waters," and they look terrible.
You have two real fixes for this. First, you can lower the rod. If your window is small, a 72-inch curtain is plenty. Second, you can use the "extra ring" trick. By using longer clip rings or even S-hooks, you can drop the curtain another 2 or 3 inches.
If you’re feeling fancy, buy two curtains. Use one for the window and cut the second one up to create a "border" or a valance. It sounds like a lot of work, but it’s still cheaper than buying one single "real" velvet panel from a specialty store.
Real World Examples: Where This Works Best
I've seen this used effectively in nurseries. Why? Because kids are sticky. If a toddler wipes their chocolate-covered hands on a $200 silk drape, that’s a tragedy. If they do it to a polyester shower curtain, you just toss it in the laundry with the towels.
Rental properties are another prime spot. If you’re only living somewhere for a year, you don't want to invest in custom window sizes. A 72x72 shower curtain fits almost every standard rental window perfectly. It’s the ultimate "pivot" for someone who moves frequently.
Let's Talk About Light Blocking
One thing to be careful about: opacity. Shower curtains are designed to give you privacy in the bathroom, but they aren't "blackout" curtains. If you're a shift worker trying to sleep during the day, a single fabric shower curtain won't cut it. You'll still see a soft glow coming through the fabric.

However, because shower curtains are so wide, you can easily "double bag" them. You can hang a cheap blackout liner behind the decorative shower curtain on the same set of clips. It adds bulk, makes the window look more substantial, and kills the light.
The Sustainability Angle
It’s surprisingly eco-friendly to repurpose textiles. Instead of buying "new" window treatments that come wrapped in layers of plastic and cardboard, many people are sourcing vintage fabric shower curtains or high-quality cotton ones from thrift stores. Cotton is biodegradable. Polyester is recyclable. By using what's already available in the "wrong" aisle of the store, you’re essentially hacking the supply chain.
Actionable Steps for Your Next Room Refresh
If you're ready to try this, don't just wing it.
- Measure the "Drop": Measure from your curtain rod to the floor. If it's more than 74 inches, a standard shower curtain will be too short unless you use long clip rings.
- Feel the Fabric: Only buy curtains labeled "fabric," "cotton," or "textured polyester." Avoid PEVA or Vinyl for windows unless you're going for a very specific, hyper-modern industrial look.
- Upgrade the Hardware: Throw away the plastic rings. Buy matte black or brass clip rings. This is the single most important step to making the curtain look like it belongs in a living room.
- Steam is Key: Shower curtains come folded in tight squares. Those creases will stay there forever if you don't intervene. Use a handheld steamer or a warm iron before you hang them.
- Check the Hem: If the bottom is raw or has a cheap-looking plastic weight, take five minutes to trim it or sew a clean line.
Using shower curtains as curtains is a classic case of "if it looks stupid but works, it ain't stupid." It defies the traditional rules of home decor by prioritizing utility and cost without sacrificing the visual "weight" a room needs. Whether you're trying to save money or you just can't find the right pattern in the window aisle, the bathroom section is waiting for you. Just skip the ones with the rubber ducks. Please.
