What is a mud Rhassoul? Discover our signature treatment.


Step back in time, and experience the benefits of a miracle material used by ancient Egyptian royalty and Roman aristocracy.

Immerse your skin in restorative bliss as you uncover the power of one of our planet’s natural substances.

Excavated from the depths of the Austrian Alps and brought to you by the Natural Spa factory, pure Rhassoul mud revitalises and beautifies, leaving your skin feeling and looking nourished.

The miracle mud embodies an abundance of healing minerals that work together in natural synergy to detoxify, cleanse and catalyse skin cell renewal. Its calming, moisturising properties make this natural product reputably beneficial for those suffering from irritable skin complaints, such as psoriasis and eczema.  

As part of our signature treatment range, our expertly designed Rhassoul mud experience encompasses use of our bespoke, private spa chamber, a steam infusion and exfoliating shower experience, and soothing Rhassoul mud application.

Our commodious and opulent treatment room invites the experience to be shared and allows for up to four guests to participate in an otherwise private event.   

Exfoliate and purify your skin with a seasonally scented scrub, cocoon your body in the restorative heated clay, and then bask in our tropical steam room as the natural material draws out impurities. Our signature treatment is completed with a warm shower that removes the applied mud and a body lotion to leave your skin feeling refreshed and rejuvenated.

Relax, unwind and experience the soothing powers of Rhassoul, in our newest luxury treatment.
