Ensen Onsen & Spa

4.6(82 reviews)

Tucked into the Bang Rak neighbourhood near Sap Road, Ensen Onsen & Spa brings a Japanese bathhouse concept to central Bangkok. The main draw is a mineral water pool maintained at 41 degrees Celsius, complemented by a steam sauna — making it a genuine onsen experience rather than a conventional massage spa. Guests receive two towels, a kimono, and flip-flops upon entry, and a welcome lime drink is included as part of the experience. Visitors should go in with clear expectations about what this place is and is not. There is no massage service on offer, despite the name suggesting otherwise. The facility is compact — comprising a small pool and steam room — but reviewers note it is kept clean and well-maintained. The atmosphere skews toward a local Thai clientele, and some visitors have noted it carries an openly gay-friendly character. A bar and light refreshments are available on-site, though service pace has drawn some criticism from guests. For those seeking a quiet soak, weekday evenings appear to be the most relaxed option, with crowds building later in the evening. Given the onsen-style format, the experience is best suited to travellers looking for relaxation and warmth rather than a full spa or treatment menu. It is worth confirming current pricing and opening hours directly before visiting, as this information is not readily available online.

Visitor Reviews

The Best Gay Onsen in Bangkok I really like this place there are so many good-looking people, and the food is delicious. I especially love the welcome lime drink!

The place was very clean and of a very good standard!!! But no massage. The pool has mineral water at 41 degrees Celsius and a steam sauna. You get two towels, a kimono, and flip-flops: included in the price. The bar upstairs doesn't serve alcohol. However, I was most dissatisfied with the massage. I chose the Thai massage, which was very poor, and they even charged me a 200 Baht tip upon leaving. Absolutely impertinent.

Came on a weekday 6pm, less than 5 people and when I left at 730, there were probably 15-20 people. Mostly Thai, average to skinny fat body type and they look like middle age 30+ years old. The dressing area is blinding bright with the white overhead light that feels like in an office. The upper floor where the maze and the chase areas are also brightly lit that makes the place bizarre and uncomfortable for any action. And there’s only one massage chair which is sad and lonely. The management need to reconfigure the space to make it more cruisy and cozy, have more dim and warm lights and more areas to chill. The steam room good with strong steam and maze layout and that’s where most actions happen as the upper floor maze is dead cold. 250thb for entry is the cheapest in the area but just low price won’t keep the doors open, make this place fun not sterile.

Tips for Visiting Activities & Tours

Vet Elephant Sanctuaries

Only visit sanctuaries that prohibit riding, use no chains or bullhooks, and let elephants roam freely. Elephant Nature Park in Chiang Mai set the standard. If a place offers painting shows or circus tricks, walk away.

Book Through Klook or GetYourGuide

These platforms offer instant confirmation, free cancellation on most activities, and prices that are often lower than walk-up rates. Compare with local agencies for multi-day trips where negotiation might save more.

Do Outdoor Activities in the Morning

Heat and humidity peak from noon to 3 PM. Schedule jungle treks, cycling tours, and outdoor cooking classes for early morning. Water activities are more flexible since you're in and out of the sea.
