If you’re new to colon hydrotherapy, you may be wondering what the difference is between an open system and a closed system. Both methods aim to cleanse the colon, but the experience and depth of cleansing are quite different.

At Colonic Detox in North West London, I use a closed system, and here’s a simple explanation of why — and how it works.

⭐ What Is a Closed System Colon Hydrotherapy?

(This is the system used at Colonic Detox)

A closed system is a therapist-guided treatment where purified water gently enters and leaves the colon through a sealed tube. Because everything is contained, the session feels clean, private, and well-supported.

Why the closed system is more effective

With the closed system, the water is introduced slowly and carefully, allowing the cleanse to progress through the full length of the large intestine, not just the lower part.

This means:

The cleansing can go deeper and remove more built-up waste and gas.

The treatment is more thorough and supportive for digestion and detox.

You may feel lighter, flatter, and more energised afterwards.

It’s a gentle process, but more comprehensive compared to the open system.

Extra comfort and hygiene

Waste leaves the body through a wide, sealed tube.

It goes directly into the drain

You do not need to get up or go to the toilet during the session

There is no smell, no mess, and no discomfort

You stay relaxed while the therapist guides the process and does belly massage

Many clients choose the closed system because they feel secure, supported, more detoxed and fully looked after throughout the treatment.

⭐ What Is an Open System Colon Hydrotherapy?

An open system uses a special bed and a small nozzle. The water flows in gently, and when the body is ready to release, the waste passes out into an open basin.

How the open system works:

It offers more privacy and less therapist involvement, as most of the time you stay alone in the room.

Clients release when they feel the urge.

It provides a slow, more surface-level cleanse.

Because the system is open, the water doesn’t travel as far inside the colon.

This makes it more similar to a large enema, cleaning mainly the lower part of the intestine rather than the full colon.

⭐ Which System Is Better?

Both systems are safe, but they offer different experiences.

At Colonic Detox, I use the closed system because it allows for:

A full-colon cleanse, not just the lower area,

More thorough results for bloating, gas, and sluggish digestion,

Moving old toxins out,

Complete hygiene with no mess and no smell,

A calm, guided experience where you feel supported the entire time,

For clients who want a deeper detox and a more effective treatment, the closed system is usually the preferred choice.
