Morozko is still the only maker whose tubs form actual ice at 32F, and the company is very much alive: it expanded its lineup to six models in 2026 and launched a hydrogen mineral bath partnership with Echo Water in late 2025. Entry is cheaper than it used to be, with the $12,490 Forge well under the old $15,500 single-model price, but the range now climbs to $35,990 for the two-person Arktika. The honest caveat has not changed: sub-40F chiller plunges deliver the same physiological benefits for half the money, so you are paying for genuine ice, engineering transparency and the Phoenix-built product, not extra cold-therapy results. Residential models carry only a 1-year warranty, which is thin at this price.

Renu is the craftsmanship pick of the powered lane: hand-built in Santa Ana, California, whisper quiet, with real wood or composite decks and the best body warranty in the category at 5 years on its plastic-body tubs. The catch has not changed: the chiller that does all the work is only covered for 1 year unless you pay $300 to $500 extra, and cooling runs a slow 1F per hour. The 2026 lineup is broader and cheaper to enter than it used to be, with the $7,200 Vero opening the range well below the old $9,700 floor. Buy a Renu to hold a set temperature beautifully and quietly in a space you look at every day; skip it if you want rapid cooldowns between back-to-back sessions.

You cannot buy an Edge Tub new: Edge Theory Labs has gone out of business, its site is a closure notice, and its app has been shut down. That is a shame, because the drop-stitch tub and 1HP Elite chiller were among the better portables at $3,990 to $4,990. Today this is a used-market-only play, and the math only works at a steep discount because there is no factory warranty, the chiller compressor carries unknown history, and repairs run through a paid third-party center operated by rival Inergize Health. If you find a clean used Elite for a fraction of its $4,990 last price and can verify the chiller runs, it can still be a solid tub. Everyone else should buy from a living company in this lane, Inergize being the obvious cross-shop.

The Pro's hardware is real: 316 stainless steel, a 1 HP chiller that holds a true 32F, and ozone plus UV water care that keeps maintenance low. But at $13,999 you are paying Morozko-adjacent money backed by a 1-year warranty and a 25% restocking fee if it goes back. The $3,799 to $3,999 portables are the quiet value in the lineup, carrying the same 32F chiller spec for about a quarter of the flagship price. Buy Sun Home for build quality and built-in water care, not for warranty depth. If coverage length drives your decision, Renu Therapy's 5-year body warranty beats it at similar money.
