Why people come
A complete reset, rooted in science
We differ from most detox retreats because our approach is grounded in science, not trend — we specialise in insulin resistance, monitor vital signs daily and supervise every stage of your cleanse.
01
Metabolism reset
Switch your body into repair mode — burn stored fuel, lower inflammation and rebalance blood sugar.
02
Gut health restored
Detox and probiotic shakes, targeted herbs and daily colonics clear accumulated waste and rebalance your gut flora.
03
Energy & clarity
Guests report boosted concentration, deeper sleep, radiant skin and a feeling of lightness within days.
04
Safe & supervised
A pre-fast interview, daily vitals checks and a personalised plan mean you’re cared for at every stage.
Supervised, personalised, safe
A cleanse crafted around you
From the moment you arrive, our wellness team supports you with care and clarity. You begin with a thoughtful pre-fast interview so we understand your needs, followed by a full walkthrough and a detailed support manual.
Every individual is different, and we honour that — crafting a bespoke programme tailored specifically to you, with vital signs monitored daily throughout your stay.
Nourishment & setting
Rest, restore, in a jungle-beach haven
Even on a fast, your body is cared for — detox and probiotic shakes, targeted herbs and a nourishing evening vegetable or miso broth keep you supported throughout the cleanse.
Set between the lapping waves of Haad Tien Bay and the lush island jungle, the environment itself does half the work — encouraging the deep rest and reflection that make a true reset possible.

I arrived foggy, bloated and run down. By day four I felt clearer than I had in years. The team supported me through every stage — I left feeling genuinely reborn.

Before you ask
Your questions, answered
If stress, poor sleep, bloating, low energy or sluggish digestion sound familiar, your body may be carrying a build-up that a reset can clear. Your suitability is always assessed first in a pre-fast consultation, and the programme is adjusted to your health history.
Our detox is built around controlled fasting, so regular meals are paused — but your body is fully supported with detox and probiotic shakes, targeted herbs and a nourishing evening vegetable or miso broth. If you'd prefer a gentler approach, ask us about our one-meal-a-day Gentle Cleanse.
A colonic gently flushes the colon with water to support cleansing. At The Sanctuary all colonics are self-administered in complete privacy — you're never handled by another person. We provide clear step-by-step guidance and a wellness consultant is always nearby. Colonics are only included once we've confirmed they're suitable for you.
Our approach is rooted in science, not trend. You begin with a pre-fast interview, your vital signs are monitored daily, and every stage is closely supervised by a team with over 30 years of fasting experience. We specialise in insulin resistance and craft a bespoke plan around your needs.
It lets you choose the room that suits your budget and comfort. Certain rooms work best for detox guests — particularly those near the Wellness Centre — so we'll personally recommend the right option. Just message us and we'll sort it.
For best results, ease off caffeine 3–5 days before arrival — switch coffee and black tea for green or herbal tea. Make fibre-rich vegetables and fruit your main focus, keep protein light, and avoid simple carbs, white flour, alcohol and dried fruit. We'll send full guidance once you book.
