Unlock the science-backed benefits of cold water immersion with the ALEKO Lumina Outdoor Wooden Ice Bath Cold Plunge Tub. Crafted with a 304 stainless steel interior and a striking charcoal WPC exterior with red cedar accents, the Lumina is built for daily cold plunge therapy in any outdoor setting — backyard, garden, spa, or wellness studio. Studies suggest regular cold immersion may help reduce inflammation, accelerate muscle recovery, boost immune function, and sharpen mood and mental clarity. Ships fully assembled so you can start your cold therapy practice the same day it arrives.
⚡ Note: A chiller unit is not included but a chiller hook-up is pre-installed on the tub. We recommend pairing with a compatible cold plunge chiller to maintain consistent water temperature year-round.
Deep enough for a full upright seated cold plunge — the optimal position for maximizing cold water contact and therapeutic benefit.
Food-grade stainless steel resists corrosion, bacteria, and UV degradation — keeping your water cleaner for longer between changes.
The charcoal WPC shell with stainless steel strip detailing and Canadian red cedar steps create a spa-quality look that elevates any outdoor space.
Pre-installed chiller hook-up means you can add a compatible chiller unit at any time. Arrives fully assembled — no installation required.
Unlike flat-bottom cold plunge pools that require significant outdoor space, the Lumina's vertical barrel design delivers the same full-body immersion experience in a fraction of the footprint. The upright seated position maximizes cold water contact on the torso and core — the areas most responsive to cold therapy — while the compact diameter (33.25 in.) fits comfortably on most patios, decks, and garden spaces. Pair it with an ALEKO outdoor sauna for the ultimate contrast therapy setup.
No — the Lumina does not include a chiller unit. However, a chiller hook-up is pre-installed on the tub, making it easy to connect a compatible cold plunge chiller. You can also use ice to cool the water manually. We recommend purchasing a chiller separately for consistent temperature control year-round.
Without a chiller, water temperature depends on ambient temperature and the amount of ice added. With a compatible chiller unit, you can typically maintain water temperatures between 39°F and 59°F (4°C–15°C) — the optimal range for cold plunge therapy. Consult your chiller's specifications for exact temperature ranges.
The Lumina features a built-in press-down water outlet located inside the bottom of the tub. Simply press down on the outlet to open the drain and release the water. We recommend draining near a garden area or connecting a hose to direct the water away from your foundation.
Yes — the Lumina ships fully assembled. There is no assembly required. Simply place the tub in your desired outdoor location, attach the cedar steps, fill with water, and you're ready to plunge. The entire setup process takes less than 30 minutes.
Without a filtration system, we recommend changing the water every 1–2 weeks depending on frequency of use. If you add a compatible chiller with a built-in filtration system, you may be able to extend water change intervals significantly. Always keep the insulated cover on when not in use to minimize debris and evaporation.
Yes — the Lumina is designed for outdoor use in all seasons. In warmer months, you'll need ice or a chiller to maintain cold temperatures. In colder climates, the ambient temperature may naturally keep the water cold. If temperatures drop below freezing, drain the tub to prevent damage to the stainless steel interior and plumbing components.
Absolutely — the Lumina is an ideal complement to any ALEKO outdoor sauna. Contrast therapy (alternating between heat and cold) is one of the most popular wellness practices and has been used for centuries. We recommend finishing your sauna session, cooling down briefly, then immersing in the cold plunge for 1–3 minutes for maximum benefit.
