Bottom line first: Based on real experiences from 50+ travelers, hotel star ratings don’t guarantee water quality—most five-star hotels and well-known resorts have no issues, but there have been cases of black particles in bathtubs at five-star hotels. Filters in Ubud villas and guesthouses are most likely to discolor. The key isn’t the star rating, but whether the hotel properly maintains its water filtration system. It’s recommended to bring your own filter showerhead just in case, and decide whether to use bottled water for brushing and rinsing based on your stomach sensitivity.
Recently, someone in our Facebook group asked: ‘Do I need to bring my own showerhead for bathing in Bali? Should I use bottled or drinking water for rinsing and brushing my teeth?’ The original poster noted that online info is very polarized and wanted to hear from people who’ve actually been. The comments section was incredibly active, with experiences ranging across different body types, accommodation types, and both ‘hit’ and ‘miss’ cases.
We’ve compiled over 50 real experiences from travelers who’ve stayed at various hotels and villas in Bali, and found a fascinating pattern: on the same island, water quality varies wildly between hotels. Some people’s filters turned alarmingly yellow after three nights in an Ubud villa, while others’ filters at five-star hotels barely changed color. So I decided to organize these experiences into a ‘hotel guide’ to help you know what to expect before booking.
High-end hotels and resorts: usually fine, but with exceptions
Most travelers who’ve stayed at five-star hotels and well-known resorts report the same thing: the filter showerheads they brought remained mostly clean, with little to no discoloration over three to seven days. At well-known resorts in areas like Seminyak and Kuta, most travelers used the hotel’s water for showering and brushing without any noticeable discomfort.
One traveler shared, ‘We’ve stayed at several hotels with no issues—we used the hotel showerhead directly and also used the water for brushing and rinsing.’ Another said, ‘Choose your restaurants carefully; decent hotels generally have fine water. I just boiled tap water for tea and coffee.’
But here’s an important counterintuitive finding: high star ratings don’t always mean the best water quality. One traveler staying at a five-star hotel in Kuta even found black particles in the bathtub, forcing them to use bottled water for brushing the entire stay. So while some people saw their filters yellow at five-star hotels, others at branded hotels had filters that stayed clean. The key isn’t necessarily the star rating, but whether the hotel properly maintains its water filtration system.
Ubud villas and guesthouses: the area where filters are most likely to ‘reveal the truth’
Villas and guesthouses in the Ubud area are the most likely to turn your filter yellow.
One guest shared a photo saying, ‘This is the filter after three nights in Ubud’ — the filter was clearly yellowed with visible sediment. Another traveler noted, ‘I swapped the showerhead at the hotel, but the filter didn’t get dirty. The last two nights at a guesthouse, the filter was filthy.’ This reflects that many guesthouses in Ubud have relatively simple water filtration systems, and some don’t even have an extra filter installed.
Someone said bluntly, ‘It’s not that bad, unless you’re staying at a guesthouse. Hotels are fine.’ Another suggested, ‘It depends on your own constitution, where you’re staying, and how much you’re paying for accommodation.’ So in Ubud, you really need to be more cautious.
A Breakdown of Hotel Areas by Water Quality
Based on experiences from over 50 guests, here’s a simple breakdown:
Areas with relatively stable water quality
- Well-known resorts and five-star hotels in Seminyak, Nusa Dua, and Kuta
- Boutique hotels and high-end villas in Ubud
- Beachfront hotels in Sanur
- Bottled water is usually provided in hotel rooms
Areas that require extra caution
- Guesthouses and small villas in Ubud (especially those without automatic water filtration systems)
- Guesthouses in inland rural areas
- Newly opened hotels with incomplete infrastructure
- Some so-called five-star hotels with aging plumbing
Do you need to bring your own showerhead?
Most hotel guests say it’s not necessary. “No need to change the showerhead, just shower directly—no problem.” “I swapped the showerhead at the hotel, but the filter cartridge never got dirty.” “I always stay in hotels, and the filter cartridge never changed color.”
But for those staying in guesthouses or Ubud, bringing a filter cartridge as insurance offers more peace of mind. “Ubud’s water quality is indeed a bit dirtier, so you can bring one as a backup—it doesn’t take up much weight.” “For a guesthouse in Ubud, bringing a filtered showerhead as insurance is a good idea.”
Some travelers have a practical approach: “I bring a filtered showerhead mainly because I don’t want to develop skin issues or allergies.” Others bluntly say, “If you’re the type to bring a showerhead, just skip Bali and go to Japan or Europe instead,” but that’s clearly a minority view.
The practical advice is:
- Staying at a five-star hotel: Not a must, but bringing one doesn’t hurt—peace of mind matters most.
- Staying in Ubud or a guesthouse: Bring a filtered showerhead to gauge water quality by checking if the filter changes color.
- Staying at a branded hotel: Usually not needed, but you can bring one as a backup.
Brushing Teeth & Rinsing: Hotel Water Quality Is Key
There are three approaches:
Bottled water camp: “I use bottled water for rinsing and brushing.” “I brush with bottled water, then rinse with it afterward.” “I use bottled water to brush my teeth.” “There’s plenty of water, and you can always ask the hotel for more.”
Tap water camp: “I just use the tap to brush—no discomfort.” “I brush with regular tap water.” “I always stay in hotels and just turn on the tap to brush and rinse.” Most with iron stomachs say that as long as the hotel isn’t too low-end, using tap water to rinse is fine.
The most honest feedback: One guest shared, “At the same hotel, my friend used bottled water to brush and still got sick, while I used tap water and was fine.” Another said, “Some people eat street food in India without issues, while others get sick in Taiwan.” And, “I lived in India for a year—I had diarrhea at first, but it never happened again.”
A Realistic Take:
- First time in Bali, traveling with kids or elderly, or have a sensitive stomach: Stick to bottled water for rinsing your mouth—it’s not worth the risk to save a few bucks.
- Iron stomach, frequent visitor, or staying at a nice hotel: Tap water is fine to use.
- Staying at a Ubud homestay or an unknown hotel: Use bottled water as much as possible—prevention is better than cure.
Ice, Drinks, and Street Food—The Real Culprits
Ice: Many say ice in restaurant drinks is fine, but others warn, ‘Avoiding ice in drinks is basic self-protection.’ One traveler shared a painful experience: ‘On the last day before heading home, my husband let his guard down and ordered an iced Americano from a roadside stall. Back in Taiwan, he came down with Bali Belly symptoms.’ Even those who’ve visited multiple times without issue can fall victim to a single iced coffee.
Street Food: Universally considered the biggest risk. ‘Roadside grilled corn and noodle stalls—some people eat them without issue, but high-risk groups should skip them.’ ‘Skip roadside stalls, including their drinks.’ ‘Don’t add ice to drinks; stick to sealed, chilled brand-name beverages without opening the can.’
Restaurant Drinks: These are relatively safer. Guests have shared, ‘The drinks we had at restaurants all came with ice, and we had zero problems.’ ‘We drank iced beverages at restaurants without any issues.’ The difference is that formal restaurants have much better water treatment systems and ice hygiene management compared to roadside stalls.
Practical Tips:
- ✅ Restaurant drinks with ice are generally fine
- ✅ Canned drinks and bottled water from supermarkets are the safest bet
- ❌ Avoid cold drinks and ice from street stalls
- ❌ Skip unknown drink shops
The Reality of Hotel Water Filtration Systems
Many hotels have no idea about their own water quality. One traveler shared that when asked about their water filtration system, some hotel owners couldn’t even say whether they had extra filters installed. So a ‘higher star rating’ or ‘higher price’ doesn’t necessarily mean their water treatment system is regularly maintained.
One traveler made an interesting observation: “It really depends on the area and water system—every place is different. The water comes out slightly yellowish.”
Practical Pre-Booking Checklist:
- 📧 Message the hotel to ask if they have filtered showerheads or can install one
- 📧 Ask if the bathtub has an additional water purification system
- ⭐ Check guest reviews—if multiple people mention “water quality issues” or “need to use bottled water,” that’s a red flag
- 📊 Pay attention to photos or experiences shared in reviews about filter discoloration
Practical On-Site Prevention Checklist
Before You Go
- ✅ Bring a filtered showerhead (especially for Ubud or homestays)
- ✅ Pack probiotics (take on an empty stomach every morning—prevention is better than cure)
- ✅ Get gastrointestinal backup meds from a clinic
- Headache/fever relief, stomach meds, anti-diarrhea, anti-nausea, allergy meds
Upon Arrival at the Hotel
- ☑ Check the filter color (if available) to see how long it’s been since it was changed
- ☑ Test the clarity of the shower water
Daily Prevention
- ✅ Brushing teeth & rinsing: use bottled water or hotel-provided water (especially at homestays)
- ✅ Drinks: ice at restaurants is fine, skip street-side stalls
- ✅ Canned drinks are the safest bet
- ✅ Keep stomach meds handy just in case
- ✅ If you do get sick: Check out this quick self-help guide
A Practical Tip: Some travelers suggest, ‘Before and during your trip, take probiotics on an empty stomach at breakfast. On the first day, mix a bottle of Taiwanese mineral water with local water (a way to adapt to the local water during travel), then you can drink the local water directly.’ This gradual approach gives your digestive system time to adjust.

An Honest Conclusion
Choosing a hotel is also about choosing its water filtration system. Bali isn’t a place where a 3-star or 2-star rating automatically means poor water quality, but if you end up at a hotel with outdated facilities and an owner who doesn’t care, that’s a different story.
One traveler summed it up: ‘Bali isn’t India, so there’s no need to be overly anxious, but prevention is better than cure—don’t let Bali Belly ruin your entire trip.’
Others added, ‘It’s better to be over-prepared’ and ‘Pack some stomach medicine, then just enjoy Bali.’
The reality is: Some people still need bottled water to feel at ease even in a five-star hotel, while others stay in a villa and drink straight from the pool without any issues. But since most people don’t visit Bali often, rather than gambling on that slim chance, it’s better to be a little over-prepared—it won’t take up much weight or cost much, but it’ll give you peace of mind throughout your trip. That’s the best deal. 🌴
