The Contrast Bundle brings heat and cold together in one complete recovery setup, pairing the Mira Natural Sauna with the Black Brainpod 2.0 Cold Plunge.
Move between traditional sauna heat and cold immersion at home, with two purpose-built systems designed to make contrast therapy easy to incorporate into your routine. Choose any Mira size to create the setup that best fits your space.
The Mira combines natural materials, Wi-Fi connectivity, and app-controlled heating, while the Brainpod 2.0 delivers the cold immersion experience Polar Monkeys was built around. With temperature ranges of 104°F–194°F in the sauna and 32°F–107°F in the Brainpod, you can move across the full spectrum of heat and cold.
Purchase them together and save 10% compared with purchasing each system separately.

Setup
The two systems ship separately using the freight method best suited to each product, with independent tracking and delivery scheduled within the same general window.
Mira Sauna: Requires on-site assembly and a dedicated 240V circuit sized to the selected heater. Before installation, prepare a level, stable, load-bearing surface. A concrete pad is recommended for permanent installations; a properly reinforced, treated-wood deck or platform may also be used when designed to support the full weight of the sauna and its occupants.
Brainpod 2.0: Plug-and-play on a standard 110V outlet. Simply position the plunge on a level surface, fill with a garden hose, and connect the system. No plumbing is required.

Maintenance Tips
Mira: Allow the sauna to ventilate after each session, wipe benches and interior surfaces as needed, and periodically inspect and rearrange the heater stones. For outdoor installations, maintain the exterior wood finish according to the recommended care schedule.
Brainpod 2.0: Allow approximately five minutes per week for routine water care using the recommended sanitation kit. Automatic ozone filtration helps maintain water quality between sessions. Drain and refresh the water as needed using the built-in drainage system.
Maintenance tips
Mira: ventilate after each session, wipe benches with water only, check the heater's stone bed periodically, and maintain proper exterior surface treatment (required by the warranty for this outdoor-rated cabin).
Brainpod: ~5 minutes per week with the recommended sanitation kit; automatic ozone filtration keeps water clean between sessions; drain and refresh via the built-in drain valve or side drainage.

Brainpod 2.0 carries a 2-year limited warranty covering defects in materials and workmanship, with free shipping on warranty claims within the continental U.S.; extended 3-year and 5-year options are available at checkout.

Frequently asked questions
What is included in the bundle?
One complete hot-cold recovery setup, with all their respective accessories. You get an Auroom Mira cabin sauna with its matched Harvia Spirit heater, paired with a Brainpod 2.0 Residential cold plunge in Black, Standard configuration.
How much does the bundle save versus buying separately?
The Small bundle (Mira S + Brainpod) is $27,868.50, against a combined regular price of $30,965.00. That is a savings of $3,096.50. The Large bundle (Mira L + Brainpod) is $35,248.50, against a combined regular price of $39,165.00, for a savings of $3,916.50. Both reflect a 10% bundle reduction.
Can I choose a different Brainpod color or finish?
Not within this bundle. The Brainpod Residential ships in Black, Standard configuration to keep the bundled pricing intact.
Which Mira size should I choose for the bundle?
Mira S seats two and suits a single user or a couple building a daily hot-cold practice. Mira L seats up to five and suits a household or a home gym built around group recovery sessions. Full interior dimensions and heater specifications for each size are listed on the Mira product page.
Do the sauna and the cold plunge ship together?
No. The Mira sauna ships directly from the supplier, crated in wood and delivered by appointment. The driver lowers it to ground level at curbside, which excludes any path or doorway narrower than 90 inches; their team contacts you before the ship date to confirm access. The Brainpod 2.0 Residential ships from Polar Monkeys with white glove delivery included, so the crew brings it into your room of choice and discards all trash. Because the two ship from different points, delivery dates wont align exactly.
What does installation look like for each system?
The Mira sauna takes up to two days to build and requires two to three people on-site for assembly. A certified electrician must complete all electrical connections. The Brainpod is plug and play, with an install time of 20 minutes or less. Schedule a video call with our team for guided setup assistance.
Are the products in this combo build by Polar Monkeys?
The Brainpod is a Polar Monkeys system, designed and engineered in-house. The sauna cabin is made by Auroom and paired with the Harvia Spirit heater from Harvia.
How does warranty coverage work across the bundle?
The Mira cabin carries a 2-year manufacturer warranty from Auroom, and the Harvia Spirit heater carries its own 2-year warranty, extendable to 3 years with registration. Both are handled directly with Auroom and Harvia. The Brainpod 2.0 Residential carries Polar Monkeys' standard product warranty; contact us directly for a claim on that component.
