  • Love the Alaskan

    I ordered the Alaskan cold plunge and chiller with the steps, cover and waterproof chiller cover. It’s an extremely stylish cold plunge in comparison to other tubs on the market. Most important I feel great starting my day with a plunge every morning. I highly recommend this product and all the accessories that go along with it!

  • Super happy with my purchase

    Bought the Alaskan cold plunge and it is awesome! The lid came a little warped, but Jake and the redwood stuff addressed that right a way and sent a new lid. Couldn’t be happier with this purchase

    I honestly could not be more happy with my purchase, nor with the company in general. I have been using my cold plunge for a little under a month and I’m so impressed by its craftsmanship, its ease of assembly, and efficiency at cooling quickly using the chiller. Its sleek design is beautiful, and I can already sense changes in my body and overall wellness. I look forward to using it for years to come. The customer service throughout the purchasing and assembly process was spectacular and when I had questions they were available, thoughtful, and thorough. I would recommend Redwood Outdoors to anyone seeking a cold plunge or sauna. A remarkable company that sells an outstanding product!

  • Waterproof Chiller Cover

    Waterproof Chiller Cover

    Keep your chiller safe and dry in the rain with this waterproof cover. Comes with velcro strips so you don't have to disconnect your water hoses before covering the chiller. The waterproof chiller cover comes is made to fit over both chiller models and fits over the chiller's filter.

    The cover must be removed while the chiller is in use. Covering the chiller while in use will damage the machine.

  • Spare Filter Cartridge

    Spare Filter Cartridge

    Keep your water squeaky clean by rotating your filter cartridges. We recommend purchasing a spare cartridge and keeping it immersed in a cleaning solution. Each month, swap out the filter cartridge in the chiller with the spare filter to keep your water maximally clean and healthy! This will save you time and increase the life of your filter cartridges as well as your chiller!!

    Note that 1 filter cartridge is included with your chiller.

    Our SpaGaurd bromine spa cleaning kit is perfect for keeping your water fresh and safe. We recommend bromine as a gentler alternative to chlorine. Bromine is an ideal choice for families with children who use the tub regularly. Bromine does not have the same strong smell as chlorine and is less abrasive on your skin, making it a very popular choice with our customers.
