With a $38 entry ticket, you can spend an entire day at the Yunomori Onsen & Spa at Kallang Wave Mall.
Choose from 11 hot pools to soak in inside the 16,000 sq ft establishment and, for an extra fee, opt for additional treatment options such as traditional Thai and foot massages.
And if you get hungry from all the pampering, there is a full-fledged eatery called Yunomori Cafe for you to refuel.
On the menu are more than 30 items ranging from udon to donburi (rice bowls) to kakigori (a Japanese shaved ice dessert).
In fact, food, especially of the hearty, full-meal variety, is becoming a feature in several spas here.
Unlike in typical spas where patrons might sip on tea or nibble on a light post-massage bite, customers at these places can hang out for hours at a stretch, enjoying facilities such as saunas and jacuzzis and have a full meal if they feel like it.
Yunomori onsen is one of three in Singapore offering meals from fullyequipped kitchens to patrons on top of their regular spa treatments.
The other two are g.spa in Guillemard Road and Calla Spa in Suntec City.
Though they are run by the same person, spa veteran Mr Gary Tang, they are positioned to meet the needs of different demographics, says Mr Joseph Goh, 30, marketing manager for both spas.
"Over the years, g.spa has attracted businessmen and families while Calla Spa is mostly frequented by shoppers, tourists and executives working in the Central Business District," he says.
But what they have in common is a free-flow dining area.
At g.spa, you can tuck into local delights such as nasi lemak, chicken rice or laksa.
At the more upmarket Calla Spa, fine-dining fare, including grilled ribeye with wasabi brown sauce and wild mushroom soup with truffle oil, is served in a casual bistro setting. The menus for both spas change weekly.
Including food into the mix is part of positioning the spas as one-stop lifestyle hubs, says Mr Goh. He adds that all guests make a stop at the dining areas.
To enter Calla Spa, guests pick from one of three basic packages that start from $29 for a two-hour period.
The lowest-priced package includes a free flow of certain food items and unlimited use of the mineral pool, sauna, steam room and relaxation lounge. There are add-on treatments too.
At g.spa, guests either go for the standard rate of $68 to use the basic facilities or select a spa treatment (which start from $130). To sweeten the deal, all guests can stay up to 24 hours.
Over at Yunomori Onsen & Spa, the cafe is open to non-guests too. In fact, a small percentage of diners come for the food only, says general manager Yuya Egawa, 46.
He adds that the cafe is part of the quintessential onsen experience in Japan. "After taking a bath in the onsen, people get hungry and want to have a meal."
The onsen and spa started its first branch in Bangkok in 2012 and the Singapore one opened in late May this year and is a joint venture by local companies Onsen Retreat And Spa and Japanese lifestyle company Komars Group, which runs the Ramen Champion chain.
Prices for a meal at the 35-seater Yunomori cafe start from $8 for a bowl of cold Hiyashi udon or soba.
Teaching consultant Jasmine Tan, 38, who has visited the onsen twice, treats it as a one-stop escape destination.
She says: "I can have a bath, a massage, eat, read and even do my work here as it's quieter and the space is big."
It was the food offerings at g.spa that attracted sales and event manager Jess Chong, 32, and her husband to spend a weekday there.
She says: "The food makes it more worthwhile and convenient as we can have our meals in the spa and spend a longer period there."
Where to eat spa cuisine

The restaurant at Espa, the spa at Resorts World Sentosa, melds Western and Asian flavours.
Tangerine is helmed by consulting chef Ian Kittichai, who is a celebrity chef from Thailand.
