[01 — Overview]
Astungkare Spa is a 24-hour mobile spa working across Bali. A trained therapist arrives at the guest's villa with oils and linen, booked through WhatsApp, with service areas covering Canggu, Seminyak, Ubud, and the rest of the island. Onyx handles the brand, the site, the social feed, and the paid media.
Bali's spa market is crowded with brick-and-mortar wellness brands competing for the same walk-in foot traffic. Astungkare took the opposite bet: the spa comes to you, 24 hours a day, across the island. The job was to make that promise feel as effortless online as it does in person, a hero that tells you the earliest tonight slot in real time, treatments priced and explained without spa-speak, a cancellation policy you can read before you book, and a single tap to WhatsApp the therapist directly. The brand is dark gold and serif-led, the kind of restraint that lets the service do the talking. Site, social, and paid media all run from the same studio so the voice and the offer stay aligned across every surface.
[02 — The challenge]
What wasn't working
- 01The mobile spa promise was harder to explain online than in person.
- 02No way to show a guest the earliest slot available tonight.
- 03Treatments and the cancellation policy were not written down anywhere readable.
- 04Nothing held the brand, the social feed, and the ads to one voice.
[03 — The solution]
What we built
- 01Built a custom site on a dark gold, serif-led editorial system.
- 02Put a live earliest-availability indicator on the hero.
- 03Set up WhatsApp-first booking with a sub-five-minute reply commitment.
- 04Wrote the treatment catalog with mobile-spa logistics, cancellation policy, and service area pages.
- 05Run the always-on social feed alongside Meta and Google ads management.
[04 — The result]
What's different now
[In their words]
“We wanted the website to feel as calm as the treatment itself. Onyx built the site, runs the social feed, and manages the ads, bookings flow straight to WhatsApp and nothing falls through the cracks. The site converts at three times what we projected.”
