DimensionsRedwood's product page lists the tub at 37 in in diameter and 40.5 in tall. Its FAQ says about 31 in across and about 40 in tall, and neither page says which figure is the inside. It holds up to 130 gallons and seats one person. The tub weighs 250 lb empty and 1,334 lb with water, per the product page. The FAQ rounds the filled weight to about 1,350 lb. The movable steps are 23.25 in wide, 21.25 in long and 25 in tall. The tub ships in a wooden crate 3 ft 2 in wide, 3 ft 4 in long and 3 ft 4 in tall.It fits most body sizes up to 6 feet. Above that, full-body immersion can feel tight and your knees may sit above the waterline. For taller people, Ice Barrel suggests its larger Ice Barrel 500, rated up to 6 ft 9 in and priced at $1,749.99 on Oct 20. The barrel is 35.5 in wide, so measure your doorway before you order.
InstallationWithout a chiller, the tub needs no outlet or plumbing. Assembly takes three steps with the supplied parts. Screw the two handles onto the lid, take the steps out of the tub, and screw the drainpipe onto the bottom outlet. Redwood's manual asks for a strong, level foundation. That means a concrete pad at least 4 in thick with mesh, or a deck an architect or building engineer has checked for the weight. It advises against dirt or grass. The drain has a 3/4 in garden hose connection and works by gravity. The manual suggests a 1/4 HP submersible utility pump, around $60, to move the water farther. A freight truck delivers the crate to the curb by appointment, and someone has to be there to sign. The page's delivery estimate showed an order on Oct 23 shipping Nov 3, and Redwood calls delivery times estimates.No chiller is included, so the barrel needs no outlet, circuit or plumbing. You assemble the drain spout yourself, and the wrenches shown in the replacement parts kit aren't included. Ice Barrel says most people can get in without a step stool. It ships within 2 to 3 business days and should arrive 7 to 13 days after you order. A full barrel weighs about 700 lb, so the floor or deck has to carry that.
MaterialsThe exterior and lid are Canadian heat-treated hemlock. The spec table lists a molded acrylic liner, while the FAQ calls it fiberglass. The FAQ says a reflective insulation layer sits between the liner and the wood. The stained model comes with a clear linseed-oil primer that Redwood says protects the wood for about 12 months. The FAQ then suggests a marine-grade sealer for the tub, the steps and both sides of the lid. The manual says to reapply stain and seal every 1 to 2 years.Thick polyurethane foam insulates the barrel and the lid. Ice Barrel says it's made in the USA from recycled materials, and its FAQ goes further and says 100% recycled. The design is listed as patent pending.
WarrantyOne year from delivery, per Redwood's warranty policy for cold plunge tubs. It covers defects in materials and workmanship for the original buyer. Redwood chooses between replacement parts, a replacement tub or a full or partial refund. Labor, installation and removal aren't covered, and Redwood pays reasonable shipping only on returns it authorizes. Freight damage, cosmetic blemishes and poor water maintenance are excluded. The tub must not be operated, stored or left filled at or below 32°F unless it's winterized, and freeze damage isn't covered. Claims go by email with proof of purchase and photos or video. Redwood's chillers are also covered for 1 year.Three years on the barrel, per Ice Barrel's warranty page, which caps its limited lifetime warranty at 3 years. It covers material defects when you use the barrel as intended and maintain it. Ice Barrel repairs or replaces the barrel free, but not the shipping and handling. Cosmetic wear from use and weather, such as fading, isn't covered, and neither are improper installation, misuse, unauthorized changes, delamination after the first year or damage to a deck or patio. It covers only the original buyer and non-commercial use.
Returns30 days from delivery, and Redwood must approve the return in writing first. Redwood decides whether to give a full refund, a partial refund or credit, less shipping and handling and other costs. The tub must come back disassembled, palletized and in its original wood crate. The policy doesn't say who pays return freight or name a restocking fee. An order with a cold plunge is held 7 days before processing. Canceling in that window is free, and after it the charge is 3.5% of the order. Damage has to be noted on the delivery paperwork and emailed to Redwood within 7 days.30 days from delivery, minus a 30% restocking fee that also covers return shipping. The original shipping isn't refunded, and the barrel must come back in its original condition and packaging. Ice Barrel's steps say to request a return label within 30 days of the order date, which can be shorter than 30 days from delivery, and someone has to be there for the pickup. Refunds come 1 to 2 weeks after Ice Barrel accepts the return. Canceling before the order ships costs 4%.
