The Spa Experience: What’s Included and How It’s Set Up

The Ark’s thermal circle is designed to be a calming retreat rather than a busy spa. The space is adults-only, which instantly sets a tone of tranquility, away from Bali’s lively crowds. You’ll start with the pine-wood sauna, crafted from soft Scandinavian lines and warm, even heat at around 90°C. The design is minimal yet inviting, encouraging you to settle in and let your muscles unwind.

The sauna’s heat is intense enough to soften muscles but maintained at a comfortable level for a sustained session—ideal for those looking to open up tightness or simply enjoy the warmth. While some might find the heat a bit strong initially, the gentle atmosphere makes it easy to relax after a few minutes.

Next, you’ll step into the steam dome—a standout feature, especially since it’s among the few in Bali that offers an aroma-infused experience. The steam is rich and humid, combined with soft binaural beats that accompany gentle aromatherapy. Many reviewers mention how the environment encourages slow, deep breathing, which enhances overall relaxation.

Between sessions, the cold plunge pool offers a quick, invigorating dip to stimulate circulation, while the outdoor swimming pool provides a refreshing alternative. The contrast between hot and cold is what really resets the nervous system and leaves you feeling energized and clear-minded. This cycle can be repeated as often as you like during your 3-hour pass, which provides plenty of flexibility.

Surrounding these thermal zones are lounge chairs, quiet seating areas, and a lush tropical garden. The natural materials, warm lighting, and greenery cultivate a peaceful, almost meditative environment. For a grounding moment, there’s a fire-pit lounge, perfect for winding down between rounds.

Optional Add-Ons: Massages and Extras

To deepen your relaxation, 60- or 90-minute massages are available as extras. The highly praised signature massage by Manik is a highlight for many guests, often leaving them feeling completely renewed. The addition of a massage complements the thermal experience perfectly, helping muscles relax further and promoting mental clarity.

Towels, infused water, lockers, and showers are included, making the visit comfortable and convenient. You only need to bring your swimwear, as nudity isn’t permitted, and the space is designed to maintain a respectful, mature environment.

The Experience in Practice: A Typical Visit

Your day at The Ark begins by entering the gated, tranquil environment in Pererenan. Once inside, you can choose to start with the sauna, where the warm pine wood and calming atmosphere make it easy to settle in.

After about 10-15 minutes, you’ll move into the steam dome. Here, you’re enveloped by humid heat infused with soothing aromas and accompanied by gentle sounds—an almost meditative environment. Some guests find the steam dome to be a unique Bali experience, thanks to its aromatherapy and sensory design.

The cold plunge pool is usually a quick dip—refreshing and invigorating. Many find that this contrast helps boost circulation and clarity, leaving them refreshed for another round or simply ready to relax in the outdoor area. You can repeat this cycle as many times as you wish within the 3-hour window.

Throughout your thermal session, you’ll find plenty of quiet zones where you can sit or lie down, soaking up the peaceful ambiance. The fire-pit lounge adds a cozy touch, perfect for grounding yourself between heat sessions.

The optional massage is booked separately, but many guests find it the perfect way to conclude their thermal journey. The staff, including experienced guides, are happy to offer tips if you’re new to thermal cycling, ensuring you get the most benefit from your time.

What We Loved About The Ark

Design and ambiance are top-notch, with natural elements and a Scandinavian-inspired aesthetic that fosters calm. The aroma-infused steam dome offers a sensory-rich experience that’s rare in Bali and adds a layer of depth to the thermal cycle.

The staff, especially guides like Manik, are praised for their professionalism and attentiveness. Guests say she was “amazing,” and her massage helped leave them feeling “like a new person.” This personalized touch makes a difference when seeking true relaxation.

The setting outside the thermal zones is equally inviting—lush gardens, sun decks, and quiet corners create a haven away from Bali’s lively streets. This environment promotes mindfulness and peaceful reflection.

Flexibility is another plus—since the experience is self-guided, you can create your own rhythm, whether you prefer longer sauna sessions or more time in the steam dome. The staff are available to help if needed, making it suitable even for first-timers.
