An underground Himalayan salt spa in Uptown Waterloo

Salt Secret is a Himalayan salt spa built around the calming properties of real Himalayan salt. Every visit, from a single salt cave session to a full spa circuit, is built around one goal: a genuinely quiet space to slow down and recharge.

Owner Nancy Bishay, who also founded Derma Secret, spent time researching the history and traditions of salt therapy before bringing Salt Secret to life. She sourced the spa's Himalayan salt ethically and sustainably, and built an underground space designed to feel like a real escape from the everyday.

Self-care isn't just a buzzword to me, it's a necessity. My kids had gifted me the most beautiful experience at Salt Secret in Waterloo, and I'm still floating from it. From the moment I arrived, Joycelyn made me feel completely welcomed and cared for. She guided me through every step of the experience, starting in the salt sauna, followed by the essential oil-infused steam room.

“Salt Secret is truly a hidden gem. From the moment I arrived, I was greeted into a calm and relaxing atmosphere that immediately helped me unwind. The spa is beautifully designed, with a soft yellow glow from the salt walls that truly made me feel peaceful. My massage was exceptional, professional, therapeutic and incredibly relaxing.”

“What an amazing experience. Darlene is such a beautiful soul, she made it so cozy and comfortable for us both to relax and feel at home within the space. We did the circuit with the sauna, steam room, then salt cave, and the salt cave is truly a unique experience. It felt so relaxing.”

“What an absolutely spectacular hidden gem in Uptown Waterloo. John was an incredible host, and made me feel comfortable and relaxed from start to finish. Nabihah is a dream massage therapist. I left feeling recharged and relaxed, and I can't wait to go back.”

Questions before your first visit

What is halotherapy?

Halotherapy, also known as salt therapy, is the practice of breathing air with microscopic Himalayan salt particles dispersed into it, in a room built to mimic a natural salt cave.

What should I wear in the salt cave?

Comfortable, loose clothing is recommended. The salt may have minimal contact with your clothing.

How should I prepare for my first visit?

Arrive in comfortable clothing and plan to relax. We recommend hydrating beforehand, and arriving at least 20 minutes before your appointment.

Are there any side effects?

Halotherapy is generally considered safe. In some cases mild throat irritation or coughing can occur, and this is usually temporary.

Who should check with a doctor first?

If you have heart disease, kidney disease, diabetes, high or low blood pressure, or are pregnant, please consult your physician before your visit.
