Spa & Wellness

L’Institut Aspria by Sisley is an oasis of tranquility right in the heart of the city.

In 2014, Aspria Avenue Louise forged a partnership with luxury skincare brand Sisley to create a spa like no other – and the first Sisley spa in the country. Today, L’Institut offers unique blend of relaxation and beauty treatments for women and men, with expert facials, wraps and massage rituals using the brand’s luxurious skincare products, including Sisley’s famous skin-restoring phyto-aromatic face treatments.

Equally outstanding are our sauna, hamman and jacuzzi, perfect for relaxing and rejuvenating, whether soothing your muscles after a workout or just de-stressing from the world.

L’Institut is accessible to non-members.

Sauna, hammam and relaxation

Allow tension to fade and muscles to unwind in our sumptuous relaxation areas.

We all get caught up in the stresses of the modern-day world; L’Institut gives you the chance to unwind and destress completely in our hot sauna and steamy baths, or by taking a leisurely swim in our calming 16m pool.

Time spent in the spa offers the chance to escape, relax and re-energise, whether in the purifying sauna, jacuzzi or 20m2 hammam, ideal for total relaxation after a hard workout or cleansing the skin.

Follow it with an invigorating cold shower for 20 minutes of the most profound calmness.
