Singapore’s Most Relaxing Hot Springs
If you are visiting Indonesia’s hot springs, don’t forget about some of Singapore’s hot springs and spas, often the lesser child of Korea and Thailand when it comes to spas.
In a city defined by its glittering skyscrapers and fast-paced urban rhythm, Singapore’s hidden geothermal and wellness culture offers a necessary sanctuary.
You might wonder why a tropical island has any hot springs at all. Singapore sits on a massive granite bed. Rainwater seeps deep into the earth's crust—up to 3 kilometers down—where it is heated by the natural decay of radioactive elements in the granite. The pressure then forces this mineral-rich water back to the surface through cracks in the rock.
Sembawang Hot Spring Park
As the only natural hot spring on mainland Singapore, Sembawang is the "holy grail" for purists. Reopened and modernized, it retains a rustic "kampung" (village) charm. The best thing is it is less than 10 miles from the airport, so stop stressing about your delay and ease your mind before your next flight!
The water, which originates from the Bukit Timah granite base, emerges at a blistering 70°C and is rich in chloride and sulfide, rumored to cure everything from eczema to rheumatism. Sembawang Hot Spring water is a slightly alkaline, siliceous thermal water, rich in minerals like silica, sodium chloride (salt), calcium, and trace lithium.
The four-tiered cascading pool and the "Egg Cooking" station where you can boil your own onsen eggs.
In Japanese-style onsens (Yunomori, Joya, Ikeda), bathing is typically done naked in gender-segregated areas. If you are shy, opt for a private room.
For cat enthusiasts, the Sembawang Hot Spring Park is a particularly special place. Not only is it the only natural source, but it has a famous community of "Hot Spring Cats."
These well-fed, local felines are often seen lounging on the warm stone paths or hiding among the lush lemongrass and rambutan trees of the park. They have become as much a part of the heritage as the water itself, often greeting early-morning bathers who come for their daily foot soak.
Keep your indulgence going by staying at Mandai Rainforest Resort by Banyan Tree with rooftop swimming pool, spa facilities, and a fitness room. If you are there with kids they can enjoy a children's playground, indoor and outdoor play areas, and a kids' pool.

Yunomori Onsen & Spa
Located in Kallang Wave Mall, Yunomori is the largest authentic Japanese onsen in Southeast Asia. It masterfully combines Japanese bathing culture with Thai massage. The facility features a staggering 11 different baths, including the signature Soda Bath, which uses CO2 technology to increase blood oxygen levels.
I recommend the "Silk Bath," where micro-bubbles give the water a milky appearance and deeply cleanse the skin.
Stay nearby to keep your indulgence going at the Pan Pacific with its outdoor rooftop pool, a library reading area and a fitness center. I love to have control of my food and to be able to wash clothes on vacation so I love the kitchen with a stove, rice cooker and a washing machine.

Joya Onsen Cafe
Joya Onsen Cafe in Jurong has become a fan favorite for its aesthetic appeal and the unique integration of a Tatami Cafe. It caters to those who find communal bathing daunting by offering beautiful private onsen rooms, making it a top pick for couples and introverts.
Enjoy renting a yukata and enjoy Hokkaido milk or sushi in the tatami lounge after your soak.
Note this is in a very industrial area of Singapore so would not advise staying nearby. Combine this Sembawang and keep your indulgence going by staying at Mandai Rainforest Resort by Banyan Tree with rooftop swimming pool, spa facilities, and a fitness room. If you are there with kids they can enjoy a children's playground, indoor and outdoor play areas, and a kids' pool.

Ikeda Spa
Known as the first Japanese-style spa in Singapore, Ikeda Spa at Bukit Timah is the height of boutique luxury.
Their claim to fame is the Hinoki wood tub, a precious Japanese cypress once reserved for royalty. The wood releases natural oils that act as a decongestant and stress-reliever.
Relax with the "Geisha Organic Facial" and the outdoor hinoki bath that overlooks a lush, quiet garden.
Stay nearby at the Vibe Hotel Singapore Orchard with access to Singapore’s busiest and longest shopping belt and an outdoor pool.

NekoTown (Feline Therapy Spa)
Make it stand out
Whatever it is, the way you tell your story online can make all the difference.
While not a traditional "water" spa, NekoTown represents the 2026 trend of Feline Therapy. For cat enthusiasts, this is a "mental spa." The environment is designed for maximum cortisol reduction through interaction with resident pedigree cats.
The "spa" experience here is sensory: the sound of purring (proven to lower human blood pressure), the tactile sensation of grooming, and the warmth of a lap-cat.
Enjoy the "Purr-Relaxation" sessions where visitors can meditate in a room designed with soft lighting and napping cats. If you are a cat lover, try out 14 other cute cat cafes in Singapore!

Spa-1 Wellness Centre
Tucked away in Paya Lebar, Spa-1 is a labyrinth of wellness. It doesn't just offer an onsen; it features a Himalayan Salt Sauna, a Cassia Seed Sauna, and a Menthol Steam Room.
It’s a "day-pass" style facility where you can spend six hours moving between various thermal environments.
Our top pick is the Myanmar Thanakha sauna and the free-flow vegetarian cafe.
Water Quality: ★★★☆☆ (3 stars: Clean, but the focus is more on the saunas than the purity of the water.)
Ease of Access: ★★★★★ (5 stars: Right next to Paya Lebar MRT; very easy to reach.)

Auriga Spa at Capella
For the enthusiast who wants to be surrounded by nature without leaving the city, Auriga at Sentosa is the pinnacle. Nestled in a 30-acre rainforest, the spa’s philosophy is based on the cycles of the moon. Each treatment is timed to the lunar phase to maximize the body's natural receptivity.
I love the "Vitality Pool" and the herbal steam room that uses indigenous Singaporean herbs.
Water Quality: ★★★★★ (5 stars: Pristine, luxury-grade filtration with therapeutic mineral additives.)
Ease of Access: ★★★☆☆ (3 stars: Deep in Sentosa; requires a car, shuttle, or a bit of a trek.)

G Spa
G Spa is a legendary establishment in Singapore’s wellness scene. It is a massive, nature-inspired facility that stays open 24 hours a day. It features hot and cold pools for both men and women, but the real draw is the "all-you-can-eat" buffet that is included with the entry fee.
I love the rainforest-themed decor and the ability to soak at 3:00 AM after a long flight or a night out.
I prefer to stay near the beach so went with Hotel Indigo Singapore Katong by IHG with a pool overlooking the neighborhood and plenty of sitting areas with greenery. You can also enjoy big picture windows in your room and a colorful breakfast.
Water Quality: ★★★★☆ (4 stars: Very clean, though the pools are more "jacuzzi-style" than "mineral spring.")
Ease of Access: ★★★★☆ (4 stars: Located in Geylang; ample parking and easy to reach by taxi.)
Ability to be Alone: ★★★☆☆ (3 stars: Can be busy during peak evening hours, but late-night visits offer total peace.)

Don’t miss the 5-star Japanese cuisine served as part of their "Spa + Dine" packages.
Water Quality: ★★★★★ (5 stars: Meticulously clean; modern technology used for water purification.)

Health Benefits: ★★★★☆ (4 stars: Infrared therapy provides deep tissue detoxification.)
Nearby Amenities: ★★★★★ (5 stars: Unlimited options at VivoCity and Harbourfront.)
Oasia Spa Sentosa
Oasia Spa takes a different approach to the "soak." While they have beautiful sauna and steam facilities, their focus is on Forest Bathing (Shinrin-yoku) and "recharging" in a meditative garden environment. This is the place for the enthusiast who wants their spa day to include a guided wellness journey.
I love relaxing in the "Meditation Lounge" which uses sound therapy and aromatherapy to prepare the body for the soak.
Even better you can stay onsite at the Oasia Spa with amazing wellness workshops where you can learn about sustainability, healthy living, urban farming, and self-care tips.
Water Quality: ★★★★☆ (4 stars: Focus is more on the experience than the bath volume, but facilities are top-tier.)
Ease of Access: ★★★★☆ (4 stars: Located at Palawan Ridge; accessible via the Sentosa Express.)
Ability to be Alone: ★★★★★ (5 stars: Designed for mindfulness and silence.)
