Brass Monkey partnership with


We share a common goal with Sunlighten, for the health and wellbeing of our customers, as well as those who want to learn more about the benefits of the heat or the cold.

The Brass Monkey and Sunlighten stories stem from a past personal experience and it shows in the passion they plough into their products. They have 20 years experience designing saunas that harness the power of infrared light for a deep and effortless sweat. With patented technology, each of their products come with a different light combination and levels of functionality, in a range of sizes and styles. These guys really are masters of heat and light, with saunas that come ready set with programmes designed for different specific health benefits, all at the touch of a button with a sleek LED control panel. Brass Monkey ice baths and plunges can be custom built to match your sauna, creating a complete heat contrast experience that looks as good as it makes you feel.  

Key Considerations

While our ice baths and plunges are made to be super simple to install and maintain, here are common considerations to consider ahead of your purchase.

Air Flow

The mechanical parts of our bath must have access to fresh air. Every ice bath and plunge has two grills. One at the rear, as shown in the picture, and one on the right as you look down the product. We can flip our units if required for a small charge. If you experience ambient temperatures above 42°C please inform us before you buy.

When thinking about where you will locate your ice bath, please consider the dimensions to ensure there are no obstacles, such as fences, gates, or doors, that would block the bath. Our ice baths favour a smooth, hard, flat floor to wheel into position (they weigh as much as a piano). Sometimes we need to call in specialists to support delivery. If you are overseas, you will need to make your own arrangements for moving the ice bath from the kerb to the final position.

To keep your water clean, we recommend changing your filter monthly and your UV bulb annually. This should mean you only replace the water every 6 months. For these natural wood finished products, we'd recommend you use Osmo oil annually, to protect the wood and bring longevity to the finish.


Please view a summary of FAQs below. You can view more here. If you have further questions, please contact us.

Our patented process allows us to freeze the bottom of the ice bath, creating and releasing a 20-30mm sheet of ice. We call this whole process an Ice Cycle. Our ice baths run continuous ice cycles until the desired water temperature is achieved, you choose this between 0.2°c and 10°c. The lower temperature will make more ice; ice will appear from 0.8°c and below.

The units are designed to live inside or outside. They are IP44 rated. Outside, it's helpful to be under a canopy, but not essential; this is more for helping protect against direct sunlight on very hot days. The units are freestanding and require no integration. What you will need, a solid and level floor, a standard house power supply near and a hosepipe.
