The Big Celebrity Detox

The celebrities check in and get a baptism of fire with some urine therapy, which is about as enticing as it sounds. And one celeb makes a big decision after a challenging purge-inducing ceremony.

The celebrities enter stage two of the detox: anger. Martin Roberts is surprised by a spanking session, before tempers fray at the evening's ceremony.

Nude mirror gazing brings the celebs face-to-face with their shame. An intense treatment has a profound effect on some. And Princess Olga is starting to soften.

The celebrities face death with some open grave therapy. And the boys get coffee enemas.

The celebrities face a daunting arrow breaking ceremony. And while the rest of the group head off for an inner purge, for one celeb, enough is enough.

The remaining celebrities brave fire and ice, before bonds are forged in a cacao ceremony that involves lots of chocolate - none of it to eat, though

The penultimate stage of the process focuses on joy. But for Martin Roberts, a gong bath doesn't have the desired effect. And David Potts has a horrible facial.

The detox is coming to a close - but not before the celebs endure intense temperatures in a sweat lodge. Will anyone leave the process with a new sense of self?
