Treasure Spa (Siam Square One, 6th Floor)
Treasure Spa Siam Square One is the upgrade on this block. Treasure works in private spa suites with their own bathroom on the sixth floor of Siam Square One, reached by skywalk from BTS Siam exit 4, and its rate card reflects that — roughly ฿1,500 for sixty minutes at the door. It is also where booking online makes the clearest difference anywhere in Siam Square: the platform price for the 60-minute foot treatment in a spa room works out around ฿985. Two constraints come with the address: four hours' reservation notice, and a 21:30 closing time set by the mall.

Check Dates and Current Price
Pick a date to see the live rate. Reservations need four hours, so a same-day booking works only if you make it in the morning — and the morning promotion slots between 10:00 and 13:00 are the cheapest way into a suite.
You'll confirm the exact date and time on the secure booking page.
Quick answer What the suite rate buys, and the clearest online-versus-door gap in Siam
Treasure is the most expensive of the six Siam Square spas compared here and the only one selling private suites with their own bathroom rather than a room or a curtained bay. Its own price list runs to roughly ฿1,500 for sixty minutes and ฿1,950 for ninety — hotel money, for reference the Novotel spa on Siam Square asks ฿999 for a foot-and-Thai combination. That is what makes the platform rate interesting: US$30.09, about ฿985, for the 60-minute foot treatment in a spa room, which is the clearest gap between an online rate and a door rate on this block. Plan it for the day, not the evening: four hours' reservation notice, and the mall closes the spa at 21:30.
Key takeaways
- Private suites with a bathroom — the only shop of the six that sells them
- Platform rate about ฿985 against roughly ฿1,500 on the spa's own card
- Morning promotion slots run 10:00–13:00
- Reservations need 4 hours' notice in the app
- Closes at 21:30 with the mall — the earliest of the six
What the Suite Rate Buys
The room
The difference you are paying for is architectural. Downstairs on Soi 5 and Soi 6 a private room is a room; here it is a suite with its own bathroom, which is what makes the longer treatments — the 120-minute Spa Retreat, the 165-minute Marrakesh Treasure, the 180-minute Gold Element — workable without leaving the space to shower between stages. The consultation form on arrival is part of the same logic: guests set oil, pressure and problem areas in writing before anyone touches them, and reviewers describe being asked about water temperature and pressure repeatedly during the treatment.
Where the money goes furthest
Two levers cut the price. The morning promotion covers slots from 10:00 to 13:00 and runs across several treatments — a 120-minute Spa Retreat, a 90-minute hot stone massage, a 120-minute Beauty Sleep, a 120-minute scrub and aroma treatment. The other is the buy-one-get-one pairing on the two longest packages, which is designed for couples booking one room.
Outside those windows, the straight aromatic oil massage at 60, 90 or 120 minutes is the plainest thing on the card.
| What you book | Length | What it costs | When |
|---|---|---|---|
| Foot treatment in a spa room | 60 minutes | US$30.09 (about ฿985) | Any open slot |
| Spa Retreat, morning promotion | 120 minutes | Promotional rate on the platform | 10:00–13:00 only |
| Hot stone massage, morning promotion | 90 minutes | Promotional rate on the platform | 10:00–13:00 only |
| Gold Element, buy one get one | 180 minutes | Two guests, one room | Any open slot |
| Operator's own rate card | 60 / 90 minutes | About ฿1,500 / ฿1,950 | At the door |
The honest limits
It is on the sixth floor of a shopping centre, so the arrival is a lift lobby rather than a doorway on a lane, and the mall's hours are the spa's hours — 21:30, when Pela and Nature downstairs still have two and a half hours left. Guests aged under 18 are not accepted, and the spa asks that anyone with a health condition, or who is pregnant, does not book.
Booking It Without Getting Caught Out
Four hours, and why it matters
Reservations go through the app with a minimum of four hours' notice, inside a 10:00 to 21:00 reservation window. In practice that means a same-day booking only works if you request it in the morning. If you are deciding after dinner, this is not the shop — Lek takes same-day bookings by phone and runs to 23:30.
Voucher life
Ninety days from confirmation, which is comfortably longer than the 45 days at Nature and ThaiThai, and shorter than the 180 at Let's Relax upstairs on the same floor.
Cancelling
Unredeemed vouchers refund in full. No-shows do not, and arriving more than fifteen minutes late cancels the appointment — with a four-hour-notice booking in a mall, allow for the lift queue at weekends.
Finding It Above BTS Siam
Exit 4 and the skywalk
Take exit 4 — the Siam Paragon side — and follow the connecting walkway into Siam Square One without crossing traffic, then the lift to the sixth floor; the spa is room SS6009. Let's Relax is on the same floor, which makes the two easy to compare in one visit. Coming from the Siam Square lanes instead, walk back to Rama I Road and use the crossing rather than cutting across the traffic.
Questions About Treasure Spa Siam Square One
Is booking online cheaper than walking in at Treasure Spa?
For the comparable treatment, yes. The spa's own rate card runs to roughly ฿1,500 for sixty minutes, while the platform lists the 60-minute foot treatment in a spa room at US$30.09, about ฿985. It is the clearest online-versus-door gap among the six shops compared here.
How much notice does a booking need?
Four hours, through the app, inside a 10:00–21:00 reservation window. The operator confirms the exact time afterwards, so requesting early improves your odds.
What time does it close?
21:30, with the mall — the earliest closing of the six. For a late treatment, the Soi 6 shops run to midnight.
Is it suitable for couples?
Yes. The two longest packages, the 165-minute Marrakesh Treasure and the 180-minute Gold Element, are sold buy-one-get-one for two guests in the same room. The couple options across the block sit side by side here.
Is there an age limit?
Yes — 18 and over. The spa also asks that pregnant guests and anyone with existing health conditions do not book.
What Guests Say
The clerk provides hot tea while I fill out the massage questionnaire — it asks which essential oils I like and which areas and pressure I want. From cleaning to massage they kept asking about my condition, so I could raise any discomfort immediately.
The deep tissue is so good — my mom and I really liked it, the technique is great, my whole body feels light and comfortable after the treatment. The ambiance is calming.
On the sixth floor of a small department store, the decoration is beautiful, the foot massage is very comfortable, and the service is very good.
I had so much fun. As I arrived they explained the procedure so my expectation matched the actual treatment. They do it properly and not in a hurry. The tea afterwards is good as well.
