Checking into a five-star hotel usually feels like slipping into a world where everything sparkles, from the marble bathroom to the perfectly plumped pillows. Still, cleaners who work behind the scenes say that polished appearance can be misleading. Housekeeping staff are often given only a short window to turn a room around, and that time crunch means certain spots get a quick wipe instead of a genuine disinfection.
Several independent investigations, including hidden-camera reports and university microbiology studies, have found that luxury properties are not automatically cleaner than budget motels. In fact, some research suggests the opposite. Here are eight hygiene risks that cleaners themselves say guests should watch for, even in the fanciest rooms.
1. The TV Remote Control
Ask almost any hotel cleaner what the dirtiest object in a room is, and the remote control usually tops the list. A landmark study identified TV remotes and bedside lamp switches as the most contaminated surfaces, often harboring fecal bacteria and aerobic bacteria at levels exceeding those found in hospitals.[1] Even in upscale properties, remotes get passed from guest to guest for years without ever seeing a proper disinfectant wipe.
Research from Travelmath’s hotel hygiene testing backs this up at the luxury end specifically. Among five-star hotels tested, the remote control was the germiest surface, followed by the bathroom counter.[2] A quick swipe with a sanitizing wipe before you settle in for a movie night is a small habit that goes a long way.
2. Drinking Glasses and Minibar Glassware
That glass sitting on the bathroom tray or tucked into the minibar cabinet looks pristine, yet cleaners admit it is one of the easiest items to shortcut during a fast turnover. Even with strict cleaning protocols, you can never be sure if those glasses in the bathroom or at the minibar have been properly washed, and some doctors avoid reusable glassware because a prior guest may have touched or used it.[3] Worse still, cleaning staff in some properties often just rinse the glasses in the bathroom and minibar with water if they don’t appear used.[3]
An older but still widely cited investigation found similar shortcuts across the industry. An investigation of hotel cleaning habits by Arizona’s ABC15 found that 11 of the 15 hotels it tested across the country did not remove dirty glasses from the rooms for additional cleaning.[4] Bringing a personal water bottle or asking for sealed, single-use cups removes this worry entirely.
3. Bedside Lamp Switches and Charging Ports
Guests touch the lamp switch dozens of times during a stay, usually right before falling asleep or first thing in the morning, yet cleaners say this fixture is frequently skipped because it looks fine to the naked eye. One hospitality professional described exactly this kind of oversight during a recent interview. “When I enter a room and notice a dusty charging port next to the bed or a bedside lamp caked in residue, that tells me the basics may have been done, but the details were missed,” a housekeeping director explained.[5]
The scientific data on this point is striking too. The University of Houston research mentioned earlier found bedside lamp switches sitting right alongside remotes as the most bacteria-laden surfaces tested, often carrying more contamination than the toilet seat itself. A wipe-down of the lamp base, switch, and any nearby USB ports takes only seconds and closes a gap that housekeeping routinely misses.
4. Decorative Throw Pillows and Bed Runners
Those plush accent pillows and folded runners that make a luxury bed look magazine-ready rarely get laundered between guests. Cleaners note that decorative textiles fall into a gray zone of hotel cleaning checklists precisely because they are treated as staging pieces rather than functional bedding. Decorative throw pillows are rarely cleaned and can harbor bacteria and allergens, so it is worth removing them as soon as you arrive.[3]
Housekeepers at boutique and luxury properties have echoed this concern in interviews about overlooked details. Staff may skip decorative items entirely during a standard room reset, according to a head of housekeeping at an Italian lifestyle hotel.[5] If a room comes stacked with ornamental pillows, moving them to a chair or the closet floor before bedtime is a simple precaution.
5. Jetted Tubs and Whirlpool Baths
A soaking tub with jets is often the centerpiece of a luxury suite’s bathroom, marketed as the ultimate relaxation feature. Unfortunately, cleaners and researchers agree it is also one of the hardest fixtures to sanitize properly because the internal plumbing traps residue long after the water drains. Jetted tubs can harbor more bacteria and aren’t always disinfected fully, according to hospitality experts.[5]
The scale of the problem has been documented in academic testing. Researchers from Texas A&M University found that 95% of whirlpool tubs had fecal-derived bacteria in them, while 34% contained staphylococcus bacteria, and 81% contained fungi.[6] Jet systems need a full flush cycle with disinfectant to clear internal lines, a step that a rushed turnover schedule can easily shortchange.
6. Bathroom Counters and Faucet Handles
The bathroom counter might look gleaming, but multiple hidden-camera investigations have exposed a troubling shortcut some cleaning staff take. The bathroom counter and faucets can sometimes be cleaned with the same cloth used to clean the toilet, transferring germs from fecal matter onto the counter and faucets, which can lead to gastrointestional infections along with lingering GI and respiratory viruses, and worse, the same cloths may be used from room to room.[3] That cross-contamination risk is exactly why doctors recommend keeping personal items off bare countertops.
Lab data confirms just how contaminated this surface can get, even at the high end of the market. The dirtiest surface in a three-star hotel room, the bathroom counter, contained an average of only 320,000 CFU per square inch, around eight times less than a four-star hotel room and three times fewer than a five-star hotel room.[7] Packing your own toiletry kit with a barrier mat or bag for your toothbrush is a simple workaround.
7. Housekeeping Carts, Mops, and Sponges
It sounds counterintuitive, but the tools meant to clean a room are frequently the most contaminated items in the entire hallway. University research tracking bacteria across nine hotels found a surprising culprit. The highest levels of contamination were found in the maid’s cleaning cart, specifically on the mop and sponge, a problem because it means bacteria are being carried from room to room.[8]
This cross-contamination risk exists regardless of star rating, since it comes down to staffing and supply protocols rather than property price point. Such cross-contamination could be reduced by replacing cleaning liquids during housekeeping shifts, according to the researchers.[8] Guests obviously cannot inspect a housekeeping cart, but this finding is a reminder that a luxury price tag does not guarantee hospital-grade sanitation practices behind the scenes.
8. Carpets and Upholstered Furniture
Plush carpeting and tailored armchairs are hallmarks of a luxury room, yet both are notoriously difficult to sanitize between stays and often get skipped entirely in a standard turnover. Carpets, because they are rarely deep-cleaned, can be breeding grounds for bacteria and germs.[3] Suitcase wheels and shoes tracked in from outside only add to the buildup over time.
Upholstered seating carries a similar blind spot, according to physicians who study hotel hygiene. Many people probably don’t think about surfaces that are high touch but not cleaned or difficult to clean, like chairs or upholstered furniture in a room, since unlike items that can be tossed in a washing machine, these seating staples can often go without regular upkeep.[3] Wearing slippers instead of walking barefoot, and avoiding sitting directly on decorative chairs in travel clothes, can reduce unnecessary exposure.
None of this means luxury hotels are secretly unsafe or that a five-star stay is a health gamble. Most properties do maintain real cleaning standards, and the vast majority of guests never experience any ill effects from a hotel stay. Still, the research is consistent enough to take seriously: price and star rating do not always correlate with microbiological cleanliness, and a few high-touch items get missed again and again across properties of every tier.
The good news is that protecting yourself takes very little effort. A small pack of disinfectant wipes, a habit of rinsing glassware before use, and a bit of awareness about which surfaces to treat with caution can turn any hotel room, luxury or otherwise, into a genuinely comfortable place to rest.
