Hey everyone, and welcome to our little corner of the internet—straight from a hotel wardrobe supplier’s desk, where I field way more questions about “hidden” hotel features than I expected. Today, let’s talk about something that’s been popping up in my DMs, in vendor meetings, and even from hotel guests who’ve emailed us: are hotel wardrobes actually soundproof? Hotel Wardrobe
At first glance, it’s a weird question to fixate on, right? When you book a hotel room, you’re not scrolling through product specs for the closet. You’re focused on bed size, Wi-Fi speed, and whether the mini-fridge has a soda. But over the past year, as we’ve worked with 120+ boutique and chain hotels across North America, that question has become a big one—and it’s actually way more scientific than I thought it would be. Let’s break this down like I’m explaining it to a hotel owner who’s just asking, “Wait, does my closet matter if someone in the hallway slams a door?”
First, let’s get real about what “soundproof” even means. Most people use that word to mean “you can’t hear a thing on the other side,” but that’s basically impossible for any non-soundproofed structure. The actual industry term we (as suppliers, and hotel acoustics teams) talk about is STC—Sound Transmission Class. STC scores range from 0 (total sound transfer) to 60+ (near-total sound block). A typical interior hotel wall is around STC 45, which is just enough to block regular conversation, but not enough to muffle a slamming door or a kid crying.
So where do hotel wardrobes fit into this? For a long time, hotels treated wardrobes like afterthoughts—just a place to hang robes and store linens, slap in some particleboard and call it a day. But then we started noticing something: hotels that had super thin, hollow wardrobes next to noisy areas (elevator banks, ice machines, connecting doors) were getting way more noise complaints. A guest staying next to an elevator doesn’t care that their closet has matching handles—they care that the “ding-ding” of the elevator every two minutes is loud enough to wake them.
Now, here’s the science part that makes our job interesting. When a hotel wardrobe is built properly, it’s not just a closet—it’s an extra layer of sound insulation. Let’s talk about the common materials we use now, versus the old stuff. Back in 2018, most suppliers used ½-inch particleboard for wardrobe doors and ¾-inch particleboard for the side panels. That gives a wardrobe an STC score of around 22—meaning you can hear a muffled version of someone talking on the other side, and definitely hear a door slam. Now? We use a mix of medium-density fiberboard (MDF) with a rubberized backing for doors, and for the cavity inside the wardrobe, we add 2-inch acoustic foam and a layer of resilient furring strips. That’s not overkill, either—we tested it in a prototype last year, and that wardrobe pushed the overall STC of the adjacent wall by 8 points. For a hotel that’s fighting noise complaints, that’s a huge win.
Wait, but why would a wardrobe affect a wall? Let’s think about how sound travels. Sound is basically energy that moves through vibrations. If a wall is connected directly to a wardrobe frame that’s nailed straight into the wall studs, those vibrations from the hallway or next room can jump straight from the wall to the wardrobe doors, which then vibrate and make noise in the guest’s room. The resilient furring strips we add break that vibration chain—they’re like a shock absorber between the wall and the wardrobe, so sound can’t jump as easily. The acoustic foam inside the wardrobe cavity also absorbs any sound that does get through, so it doesn’t bounce around the room.
I should mention that not all hotel wardrobes are built the same, and there’s a huge gap between budget and mid-tier hotels when it comes to this. Last quarter, we worked with a small chain in the Southeast that was only paying $120 per wardrobe unit—they were using hollow core doors, no insulation, and the frame was screwed directly into the wall. They were getting 15-20 noise complaints a month, mostly from guests who booked the “quiet” rooms near the lobby. When we swapped out their old wardrobes for our mid-tier line, which has the acoustic foam and furring strips, their complaints dropped to 2 a month. That’s not a typo—18 less complaints, all because we fixed a closet.
But here’s the thing: soundproofing (or rather, sound-dampening, since true soundproofing is impossible) in wardrobes isn’t just about making rooms quieter. It’s also about privacy. We had a client in Chicago last year who had connecting rooms without a door between them—wait, no, they had a sliding door, but the sliding door was thin. The hotel installed our wardrobes on both sides of the sliding door, and that reduced the sound transfer enough that guests in both rooms said they could have a normal conversation without leaning in. That’s a big deal for hotels that use connecting rooms for families or groups, or for guests who want a little privacy but don’t want to pay for two separate rooms.
Now, let’s get into the myths I hear all the time, because that’s what this job is full of—myths that sound so real until you test them. First myth: “If I add a rug in front of the wardrobe, it will fix the sound.” No, that’s not how it works. Rugs absorb airborne sound, but wardrobes are dealing with structure-borne sound—vibrations that travel through the frame and walls. A rug does nothing for that. Second myth: “Metal wardrobes are more soundproof than wood.” We tested this, too. A thin metal wardrobe frame has an STC score of around 18, which is worse than a basic particleboard wardrobe. The solid MDF we use is way better because it’s dense, so it can stop more sound vibration. Third myth: “Only the wardrobe doors matter.” Nah, the entire unit matters. If the side panels are thin, or the cavity between the wardrobe and the wall is empty, the sound just goes through there. We recently had a hotel that upgraded their doors but kept the old particleboard side panels—they saw a 3-point STC improvement, not 8, so it’s the whole package.
Another thing that’s a big factor: location. A hotel wardrobe in a quiet guest room next to a bathroom doesn’t need to be as soundproof as a wardrobe next to an ice machine, elevator, or a staff corridor. That’s why we offer customizable acoustic layers—if a hotel has a “noisy zone” near their service entrance, we add an extra inch of acoustic foam to those wardrobes, and for quiet zones near the pool, we go with a slightly thinner (but still solid) MDF to keep costs down. It’s not one-size-fits-all, which is why most of our clients work with us to map out their hotel’s noise hot spots first.
I should also mention the guest side of this, because at the end of the day, that’s who this is for. A few months ago, I got an email from a traveler who stays at a different chain every month for work. They said the one hotel that stood out was a mid-tier brand in Denver, and the reason was that they could close the wardrobe door and not hear a single thing from the hallway, even when someone slammed their door at 2 a.m. That email stuck with me, because that’s the kind of small, underrated detail that makes a guest choose your hotel over another. Most guests won’t notice the wardrobe’s soundproofing until it’s missing—until they can hear the person in the next room snoring, or the housekeeping cart rolling down the hallway at 7 a.m.—but when it’s there, it’s a game-changer.
Now, let’s talk about what hotels care about, because I’m not here to sell you a $500 wardrobe unit (we actually have options starting at $220, if you’re curious). The biggest pushback we get is cost. “Wardrobes are already a line item—why spend extra on soundproofing?” But here’s the math: the average hotel spends $1,500 per noise complaint in lost revenue, from guests asking for refunds, canceling future bookings, or leaving bad reviews. A set of 10 custom sound-dampening wardrobes costs about $2,500 more than basic ones, and that’s $250 per extra wardrobe. If that cuts your complaints by 80%, you’ll make that money back in less than a quarter. We had a boutique hotel in Austin that did that exact math, and they told us they recouped the extra cost in 6 weeks. That’s not a bad ROI for something that doesn’t involve a new pool or a fancy lobby.
Wait, but what about maintenance? Because hotels hate anything that’s hard to fix. We’ve been supplying our acoustic wardrobes for 5 years, and we’ve had zero maintenance calls related to the soundproofing layers. The acoustic foam is sealed inside the cavity, so it doesn’t get damaged from cleaning, and the resilient furring strips are made of a durable rubber that can handle being nailed and hammered if a hotel needs to adjust a room later. The only thing we tell clients is to make sure they don’t drill extra holes in the back of the wardrobe without checking with us—because that can break the vibration chain and reduce the STC score. That’s a super easy rule, no big deal.
I also want to address the elephant in the room: COVID-era hotel upgrades. A lot of hotels invested in air purification and touchless features, but sound was something that got left behind. Now, as travel is back to pre-pandemic levels, guests are more vocal about comfort than ever. A survey from the American Hotel & Lodging Association last year said that 68% of leisure travelers and 79% of business travelers rank “quiet rooms” as a top priority when booking. That’s more important than a minibar, more important than free breakfast, almost as important as a good bed. So if your wardrobes aren’t contributing to quiet rooms, you’re missing a big piece of the guest experience.
Let’s circle back to the original question, just to make sure I didn’t ramble too much: are hotel wardrobes soundproof? The short answer is no, they’re not fully soundproof—but well-designed, acoustic-focused hotel wardrobes are incredible at reducing unwanted sound, and they’re a low-cost, high-impact way to upgrade a hotel’s guest experience. The old hollow particleboard wardrobes most hotels installed 10 years ago? Those were basically not soundproof at all. The custom, flexible acoustic wardrobes we build now? They turn a regular interior wall into a barrier that blocks most hallway noise, adjacent room conversation, and even structure-borne vibration from elevators or laundry rooms.
I think the biggest takeaway here is that hotel design is all about the small, unseen details. No guest walks into a room and thinks, “Wow, that wardrobe has a great STC score,” but they will think, “This room is so quiet, I can actually relax.” That’s what makes our job worth it—knowing that the wardrobes we build aren’t just for hanging robes, they’re for helping hotels give guests a better stay.
