Quick answer: Detox retreat costs in Thailand range from around 13,000 THB for a short guided cleanse to over 200,000 THB for a medically supervised week. Orion’s programs run from 13,440 THB for 4 nights to 125,607 THB for 28 nights, excluding accommodation. Accommodation, colonics and extra treatments are frequently quoted separately, so compare landed totals rather than headline rates.
You have probably noticed that detox retreat prices in Thailand make no sense. One centre quotes 9,000 baht for a week. Another quotes 220,000 baht for the same seven nights. Both call it a detox.
The gap is real, and it is mostly not about quality. It is about what sits inside the quoted number and what gets added at checkout. A cheap program with separate accommodation, paid treatments and extra juices can land higher than a mid-range one that includes everything.
This guide breaks the detox retreat Thailand cost question into the three price tiers that actually exist, shows what the advertised figure usually leaves out, and gives you a way to compare centres on the same basis.
Start with the honest market range, because most articles quote one tier and pretend it is the whole market.
What does a detox retreat in Thailand cost?
Thailand runs three distinct detox markets at very different prices, and conflating them is why the numbers look chaotic.
Juice and fasting programs, the most common format on Koh Phangan, run roughly 8,000 to 45,000 THB for three to twelve days. Colonic and gut-health focused programs run about 20,000 to 90,000 THB over five to ten days. Medically supervised detox sits far above both, from around 78,000 THB to well past 250,000 THB.
As a working average, a five to nine day retreat in Thailand costs somewhere between 1,800 and 3,200 USD, roughly 61,000 to 109,000 THB. Published per-day averages of 10,000 to 15,000 THB are common, but they usually describe all-inclusive packages with the room and full board folded in. Programs priced separately from accommodation, as ours are, sit well below that on the program line and then add the room. That figure climbs past 30,000 THB per day at medically supervised or luxury properties, where named examples include Kamalaya on Koh Samui at roughly 170,000 to 220,000 THB per person for seven all-inclusive nights, and Chiva-Som in Hua Hin at around 31,000 THB per person per night.
The implication: decide which tier you are shopping in before you compare anything. A Koh Phangan juice fast and a Hua Hin medical program are not competing products, and comparing their day rates tells you nothing useful.
The three tiers, and who each one actually suits
Price tier in Thai detox correlates with supervision and included services far more than with comfort.
Budget: roughly 8,000 to 30,000 THB per program
Community-scale centres, mostly on Koh Phangan and in Chiang Mai. You get the fasting protocol, supplements and usually self-administered colema equipment. Staff supervision is light. Accommodation is nearly always separate.
Suits you if: you have fasted before, you are in good health, and you want structure rather than hand-holding. Be careful if: this is your first fast, or you have any condition on the list further down this page.
Structured retreat centres: roughly 3,000 to 15,000 THB per day
Established wellness centres with a defined protocol, daily yoga, included treatments and staff who check in on you. This is where Orion sits, at the lower end of the band. Our programs run from 13,440 THB for 4 nights up to 125,607 THB for 28 nights, which works out between roughly 3,360 and 4,486 THB per day for the program itself. Centres quoting 10,000 THB or more per day in this tier are usually bundling accommodation and full board into the same figure, so read carefully before concluding one is three times the other.
Suits you if: it is your first detox, or you want yoga, treatments and community included rather than bought piecemeal. Be careful if: you are comparing purely on headline price, because this tier usually includes what the budget tier charges for.
Medically supervised: 78,000 THB and up
Physician assessment, diagnostics and clinical oversight. Appropriate if you have a medical condition, are on medication, or want lab work alongside the program.
Suits you if: you need or want clinical supervision. Be careful if: you are paying for diagnostics you do not need. This tier is genuinely necessary for some people and genuinely oversold to others.
The implication: pick your tier by how much supervision your health situation calls for, not by what you can stretch to. Then compare only within that tier.
ORION INSIGHT
At Orion, the guests who struggle most with cost are the ones who booked the minimum and then extended. It happens on nearly every intake. Someone books four nights of Cleanse and Detox, reaches day three, and realises the reset they wanted starts roughly where their booking ends. Extending mid-stay almost always costs more than booking the longer program at the start. If you are weighing four nights against eight, we would rather you booked eight and knew the number going in.
What the advertised price usually leaves out
The quoted program fee is rarely the amount that leaves your account.
Accommodation. At many centres, including ours, the program fee and the room are quoted separately. This is the single largest omission and the one that most often doubles a budget. Check our accommodation options for the room side of the equation, and note that sharing brings the per-person cost down substantially.
Colonics and treatments. Colon hydrotherapy is frequently an add-on rather than an inclusion, at roughly 800 THB per session at budget centres. Our 11 Nights Vitality Juice Detox includes two 60 minute oil massages and one 60 minute Reiki treatment in the program, with colema optional. Other centres price each of those separately. If you want to understand what these treatments involve before deciding, we cover it in our guide to colon hydrotherapy.
Extra juices and elixirs. Most programs set a daily allocation. Anything beyond it is chargeable.
Getting there. Koh Phangan has no airport. Budget for a flight to Samui or Surat Thani plus a ferry, in both directions.
Food after the program. Your break-fast days and any days either side are usually on you. Our Orion Cafe covers guests during program days only.
The implication: build a landed total before you compare centres. Program fee plus room plus treatments plus travel plus the days either side. Compare those totals, never the headline.
What is included in a detox retreat at Orion
Our programs are built so that the things you actually need during a fast are inside the fee rather than sold alongside it.
Across our detox programs, the fee covers the full protocol of juices, detox drinks, supplements and probiotics, a private health assessment at the start, unlimited yoga and meditation classes on weekdays, and access to the swimming pool, Thai herbal steam room, infrared sauna and ice bath. Massage and Reiki treatments are included on a scale that rises with program length. You also get a detox welcome meeting, a probiotic implant, use of stand-up paddleboards, and written food reintroduction guidelines for after you leave, which matter more than most people expect. Accommodation is quoted separately. The 4 night Cleanse and Detox starts at 13,440 THB, the 11 Nights Complete Detox at 43,178 THB, the 11 Nights Vitality Juice Detox at 48,318 THB, and the 28 Nights Renew and Revitalise at 125,607 THB.
Worth being straight about one thing, because it runs against what you would expect. Our longer programs cost more per night, not less. The 4 night Cleanse and Detox works out at about 3,360 THB a night, while the 28 night Renew and Revitalise is closer to 4,486, about a third higher. There is no bulk discount here, and we are not going to pretend otherwise.
The reason is that the treatments scale with length rather than staying fixed. Massage and Reiki allocations rise as the program gets longer, so a longer stay buys more supervision and more bodywork per night, not just more nights. The two 11 night options show the same logic: the Vitality Juice Detox at 48,318 THB runs about 12 percent above the Complete Detox at 43,178 THB for the same duration, because the juice protocol carries a higher daily cost of ingredients and a different treatment mix. We most often recommend the juice program to first-timers, because it builds in a pre-cleanse day and a supervised return to food.
The implication: when you compare us against a cheaper quote, add the yoga, the treatments and the assessment back onto their number first.
Current offer, valid for check-ins between May and October 2026. Detox and lifestyle programs booked with accommodation are 20 percent off, and the discount applies to the room as well as the program. That takes the 11 Nights Complete Detox from 43,178 to roughly 34,542 THB, and the 28 Nights Renew and Revitalise from 125,607 to roughly 100,486 THB. This window closes at the end of October 2026, so check current availability on the booking platform.
Why the cheapest detox is often the most expensive
A fast you abandon on day two costs everything you paid and returns nothing.
This is the pattern we see most often in people arriving from very cheap programs elsewhere. Insufficient preparation, no pre-cleanse day, no supervision, and a sudden drop to juice only. The body protests, the person quits, and the money is gone.
It is also worth being straight about what a detox program does. Your liver and kidneys already clear metabolic waste continuously, and no program flushes toxins in the literal sense the marketing implies. The National Center for Complementary and Integrative Health notes that there is no compelling research supporting detox diets for weight management or for eliminating toxins, and that severe calorie restriction rarely produces lasting weight loss on its own.
What a well-run program does provide is a protected stretch of time with rest, hydration, structure, no alcohol, daily movement and a reset of eating habits, with someone watching how you respond. Guests commonly describe sleeping better, feeling lighter and finding it easier to change what they eat afterwards. Those are reported experiences, not guaranteed outcomes, and they vary from person to person.
The implication: buy supervision and preparation, not the lowest daily rate. The pre-cleanse and break-fast days are the parts cheap programs cut, and they are the parts that determine whether you finish.
Who should talk to a doctor first
Some people should not book a fasting program without medical advice, and a good centre will tell you so before taking your money.
Speak to your doctor first if you are pregnant or breastfeeding, taking prescription medication, or managing diabetes, kidney disease, heart disease or a history of disordered eating. NCCIH specifically flags higher risk from colon cleansing for people with a history of gastrointestinal disease, prior colon surgery, haemorrhoids, kidney disease or heart disease, and notes that prolonged fasting combined with very high fluid intake can cause dangerous electrolyte imbalances.
A detox retreat is not a substitute for medical care or for treatment of any condition. If you have a health condition, tell the centre during booking rather than on arrival, so the program can be adapted or so they can tell you honestly that it is not suitable yet.
The implication: if a centre takes your booking without asking a single health question, treat that as information about the centre.
Frequently Asked Questions
It depends heavily on whether accommodation is included. Orion’s programs work out at roughly 3,360 to 4,486 THB per day for the program itself, with the room quoted separately. All-inclusive centres commonly publish 10,000 to 15,000 THB per day, and medically supervised or luxury properties exceed 30,000. Always confirm what sits inside the daily figure before comparing.
Price and safety are not directly linked, but supervision and price usually are. The things budget programs tend to cut are the pre-cleanse day, staff monitoring and the supervised return to food, which are the parts that most affect how you cope. If you are fasting for the first time, prioritise a program with a health assessment and daily check-ins over the lowest rate.
Often not, and this is the most common source of surprise. At Orion the program fee and the room are quoted separately, which lets you choose a shared bamboo bungalow or a garden room depending on budget. When comparing centres, always confirm whether their quote includes the room, and for how many nights.
Most programs run a minimum of three to five nights, and our juice program is bookable from five nights. Shorter stays work as a reset rather than a full cleanse. Guests who want the fuller experience usually choose eight nights or more, because extending mid-stay generally costs more than booking the longer program at the outset.

The bottom line
The number that matters is not the one on the website, it is your landed total: program fee, room, treatments, travel and the days either side. Once you build that figure for two or three centres in the same tier, the comparison usually resolves itself quickly, and it often does not favour the cheapest headline. Detox retreat Thailand cost varies more by what is included than by quality, and the inclusions that matter most are the ones that keep you in the program: preparation, supervision and a proper return to food. If you want our current rates and what sits inside them, the booking platform shows live availability by program and length.
