Fancy living out your mermaid dreams? We're offering an amazing experience for any would-be mermaids or mermen, where you can enjoy a mermaid-themed spa day - complete with your very own tail.

With the anticipated release of a new mermaid film this May, there's going to be a surge in interest in all things 'under the sea', and we wanted to give people a slice of the mermaid life for themselves - whilst also experiencing the best in skincare and wellness treatments.

The Rena Spa at NYX Hotel London Holborn, London, will be running an Under The Sea Spa Day, with specially ‘tail-ored’ treatments that reflect the wonders of the sea, delicious nautical-themed cocktails and the opportunity to splash around by the pool with your very own mermaid tail.


The spa day includes the choice of one of three treatments that use sea-inspired ingredients to relax and rejuvenate your body and your mind: 

  1. Mermaid's Glow Facial - 50 minutes – To achieve mermaid-like radiant and shimmering skin, this facial revitalises and repairs skin through the collagen stimulating properties of Hebridean seaweed. Suitable for all skin types, the ishga Facial will brighten and balance skin tone whilst improving texture and protecting skin from environmental damage with its potent antioxidant properties.

  2. Siren Song Massage - 50 minutes – Just like a siren's song, this massage will be both soothing and mesmerizing.  An uplifting Hebridean seaweed body oil, with the signature ishga scent of lemongrass, juniper berry, lavender and rose geranium, will be used to energise and invigorate the body (or mermaid tail!).

  3. Deep Sea Detox Wrap - 50 minutes – This treatment will make you feel like a true sea goddess. Allow the bioactive components of Hebridean seaweed to detoxify the body with this unique treatment which includes a sea salt and oil scrub and scalp massage. Antioxidant-rich seaweed gel is combined with the collagen-stimulating properties of the Hebridean sea salt scrub. The treatment will help to eliminate toxins and congestion from the body whilst improving skin tone and texture, leaving you with skin as smooth and shimmery as a mermaid's tail;

You can then pick from a specially created cocktail menu that use nautical-inspired flavours and are perfect to sip by the pool, with or without your tail on.

The spa experience, including one treatment, use of a mermaid tail, and use of the spa facilities is £210.
