Understanding your needs

In-person collaboration to match your business requirements to the best type of cold water immersion integration. We explore the experience you want to create and the ways we can make it happen.

Engine specification

With your needs understood, we build the technical specifications that fit the requirements of your facility and your business model.

Design & Finish

Whether you choose from our selection of sizes and finishes or prefer a complete custom build, we create a cold water experience that works seamlessly with your existing house style.

Brass Monkey Health
Build & Install

Each Plunge is hand-built and rigorously tested, and if plant-room integration is required, we work with you on-site to complete a meticulous installation and ensure your team is happy to take the reigns.

Onboarding

Every purchase comes with three onboarding calls. One to support the setup and two check-in calls to optimise Plunge performance or support with the first round of maintenance, such as filter changes or temperature control coaching.

Easy to maintain

The technology inside the Plunge allows us to monitor each one 24/7, and our support team is always on hand to help remotely, and in person if ever needed.

Experience design

The Pro Plunge offers a huge range of opportunities to commercially maximise your client offering. Take a look at some of the ways we’ve helped our clients elevate their guest experience, attract new customers, and increase commercial performance.

01.

A private space or gated area for chargeable self-guided programmes and experiences. Ideal for high-end spas or recovery suites and a great way to turn unutilised areas into profit.

02.

Add value to high-end memberships by laying in a premium cold experience. Great for both semi-private or open social areas of your venue.

03.

Bringing a high-end heat contrast experience to your current sauna and steam set-up enhances existing facilities with a premium approach to wellness. Ideal to commercialise any under-used space.

04.

Breathe new life and purpose into your outside space with a cold water immersion experience that works with a jacuzzi or hot tub. We can easily match the Plunge to your existing facilities.

05.

A simple upgrade to your gym that adds a different and premium angle to your fitness and wellness offering. Stay ahead of the curve as awareness of the benefits of cold water immersion continues to explode.

How it works

Patented ice cycles Patented ice cycles

Patented ice cycles

For our commercial plunges we’ve doubled our ice making power on the sides of the unit to allow safe and uninterrupted dips while ice is formed and released. When the Plunge is set to below 2 degrees, we freeze the sides of the plunge and release it in cycles, this creates 15-30mm ice sheets that break up easily and mean your ice plunge can drop to zero degrees with ice in. The ice brings a whole new level to the cold water immersion that no other product can come close to matching.

Automated Automated

Automated

Our plunges are designed to ensure you can just say focussed on your customers. We have 6 sensors all feeding into our software to ensure temperature control and ice formation is as energy efficient and precise as possible. Using our companion app you can schedule you plunge to be ready when you want it to be bringing further efficiency to your bath. On top of that receive maintenance reminders to ensure your water is always crystal clear.

Easy to maintain Easy to maintain

Easy to maintain

We designed the ice plunge to be as maintenance light as possible. Every week we’d recommend replacing your filter and once a year we’d recommend changing the UV bulb. Depending on usage you should only need to swap the water once a month, twice if heavier use. To ensure your water stays clean for as long as possible we’d always recommend customers have a shower before jumping in. Click here to view and download our Commercial maintenance Guide
