When checking into a hotel, most people focus on inspecting the bedding, checking for hidden cameras, and ensuring the room is clean. But have you ever considered boiling water and pouring it into the toilet? It may sound strange, but hotel staff and travel experts recommend this practice for a surprising reason—hygiene and safety.
This article explores why this simple habit can make a huge difference in ensuring a cleaner, healthier stay.

The Hidden Dangers Lurking in Hotel Rooms
Hotel rooms may appear spotless, but not all cleaning routines meet high hygiene standards. Budget hotels, in particular, often rush through cleaning procedures, meaning essential areas may not get the deep cleaning they need. Even in high-end hotels, certain surfaces and appliances may be neglected.
While travelers commonly check for bed bugs, unclean sheets, and dirty bathrooms, few realize that the electric kettle—a staple in most hotel rooms—may be a major source of bacteria and contamination.
Why You Should Boil Water in the Hotel Kettle Before Using It
Many hotel guests assume that the electric kettle is safe for making tea, coffee, or boiling drinking water. However, the reality can be quite disturbing.
1. Previous Guests May Have Used It for Unsanitary Purposes
There have been shocking reports of travelers using hotel kettles for cooking instant noodles, boiling seafood, or even cleaning personal items like underwear and socks. Some hotel staff members have even reported finding vomit and trash inside kettles.
The issue? Standard hotel cleaning procedures don’t always include deep-cleaning kettles. This means bacteria, mold, and lingering odors can accumulate over time.
2. Bacteria and Germs Thrive in Warm, Damp Conditions
Even if guests use the kettle for its intended purpose, a kettle that has been used frequently without proper cleaning becomes a breeding ground for bacteria. Residual water left inside can encourage the growth of:
- Mold and mildew
- Harmful bacteria like E. coli and Staphylococcus
- Limescale buildup that affects taste and safety
3. Hotels May Not Sanitize Kettles Between Guests
Unlike bedding and towels, hotel kettles aren’t always cleaned after every guest checks out. Some cleaning staff may simply rinse them out with water, which isn’t enough to kill bacteria.
By boiling water upon arrival, you sterilize the kettle, making it safer for future use.
Why Pour the Boiling Water into the Toilet?
Boiling water isn’t just for cleaning the kettle itself—it also serves another important function. Pouring it into the toilet or bathroom drain helps with:
1. Killing Bacteria and Germs in the Toilet Bowl
Toilets in hotel rooms may not always be properly disinfected. Even if they look clean, bacteria such as Salmonella and E. coli can remain on surfaces. Pouring boiling water into the toilet helps kill harmful germs, reducing the risk of contamination.
2. Clearing Drain Blockages and Eliminating Odors

Hotel plumbing systems often suffer from buildup of bacteria, soap residue, and even hair. If you notice an unpleasant smell coming from the drain or toilet, boiling water can help break down grease, bacteria, and organic matter, freshening up the bathroom.
3. Eliminating Hidden Germs in Bathroom Corners
Hotel bathrooms are one of the most bacteria-prone areas. The corners of the room, the space around the toilet base, and even the sink drain can harbor microbes and mold. Pouring hot water in these areas can act as an extra layer of sanitation.
Additional Hotel Room Hygiene Tips
Boiling water is just one precaution to take when checking into a hotel. To ensure a cleaner and safer stay, consider these additional hygiene tips:
1. Disinfect High-Touch Surfaces
Hotel cleaning crews don’t always sanitize every surface, so take a few minutes to wipe down:
- Light switches
- Remote controls
- Door handles
- Faucet handles
- Telephone and alarm clock
2. Check for Bed Bugs
Before settling in, inspect the mattress, sheets, and headboard for signs of bed bugs. Small brown stains, black dots, or tiny bugs in the seams of the mattress are warning signs.

3. Avoid Using Hotel Glassware Without Washing
Many hotels provide drinking glasses in the bathroom or near the minibar, but these may not be properly washed. To be safe, rinse them thoroughly with hot water and soap before using.
4. Use Your Own Toiletries and Towels
Even though hotels provide towels and toiletries, bringing your own is always a safer option. Hotel towels may not be washed with high heat every time, and some toiletries could be refilled rather than replaced.
Is This Practice Necessary in Every Hotel?
Not all hotels fail to maintain proper hygiene standards. Higher-end hotels and well-rated accommodations usually follow stricter cleaning protocols. However, if you are staying in budget hotels, motels, or short-term rental apartments, extra precautions are a good idea.
Final Thoughts: A Simple Step for a Cleaner Stay
Boiling water and pouring it into the hotel toilet may seem like an unusual step, but it’s an effective way to improve hygiene and protect your health. Given how frequently hotel kettles are misused and how inconsistent cleaning routines can be, taking a few minutes to sanitize both the kettle and bathroom areas is a small effort for added peace of mind.
Next time you check into a hotel, try this method—you may be surprised at how much cleaner and fresher your space feels.
