Our Renu Therapy verdict
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.
Verified on renutherapy.com in July 2026: the compact Vero runs $7,200 cold only or $7,500 with chill plus heat, the Cold Stoic 2.0 starts at $9,499, the laydown Aurelius is $9,999, the flagship Cold Stoic 3.0 runs $11,399 to $12,099 depending on deck and cover, and the wood-body Siberian Pro tops the range at $14,099 to $14,419. Every tub ships with an integrated chiller, dual filtration and ozone purification; the 3.0, Aurelius and Vero add WiFi-controlled heat. Free curbside delivery is included in the contiguous US, but the tub arrives palletized at about 350 lbs (roughly 650 lbs for the Siberian Pro) and moving it off the pallet is on you. Renu publishes no lead times; its shipping policy says they vary and are usually quite substantial, so get a written estimate before paying. The extended chiller warranty ($300 to $500 depending on model) must be bought within 364 days of shipment.

Strengths & Considerations
What it does well
- +Handcrafted and assembled in the USA (California) with up to 4 inches of high-density insulation, plus customizable tank colors and real wood or composite deck options.
- +Dual-stage filtration paired with integrated ozone purification keeps the water clear and reduces how often it needs changing.
- +Broad lineup from the compact Vero (from $7,200) up to full-size tubs, including models that both cool and heat for year-round use.
- +A 5-year limited warranty on the tank and structural components of the plastic-body models, longer than the 3-year coverage common in this category.
- +Free curbside shipping is included, and the flagship models add touchscreen plus app temperature control.
Where it falls short
Sourced, not our opinion. This is the part the brand's own page leaves off.
The 5-year limited warranty covers most tank components, but the refrigeration chiller gets only 1 year, and extending it to 5 years costs extra and must be purchased within a year of shipment.

Reviewers measured roughly one degree Fahrenheit of cooling per hour, so reaching or recovering the target temperature takes time.

The Cold Stoic 2.0 weighs about 350 lbs empty and roughly 1,145 lbs filled, ships in 6 to 10 weeks, and needs a pallet jack to move.

The flagship Cold Stoic 2.0 runs around $9,700 before optional upgrades, and returns carry a 5 percent restocking fee.

Before You Buy: Confirm These
These come from Renu Therapy's own documented terms and from owner reports, not our test results. Confirm the specifics in writing before you order.
- ?The 5-year warranty headline covers the tank, not the chiller. The chiller gets 1 year, and the extension to 5 years total ($300 on the Cold Stoic 2.0, $500 on other models) must be purchased within 364 days of shipment or the option is gone.
- ?Lead times are not published anywhere on the site; the shipping policy says they vary and are usually quite substantial. Get the current lead time in writing before you pay, and note returns carry a restocking fee.
- ?Free curbside delivery means a 350 lb pallet at your curb (about 650 lbs for the Siberian Pro). Line up a crew or pallet jack in advance, and photograph and inspect the crate for freight damage before signing the delivery receipt.
- ?The warranty is residential-only and excludes damage from poor water chemistry, neglected filter care, freezing and power outages. Keep filter and water-care records or a claim can be denied.
Chiller & Water Care
Included (1-year chiller warranty). Cools slowly at roughly 1F per hour.
Filtration; excludes damage from poor water chemistry or neglected filter care
Lane: Powered plunge (chiller built in). How the cold is made and how the water stays clean are the two specs that decide your running cost, so read these before the shell.
Key Models
Support & Warranty
5-year body / 1-year chiller on plastic tubs (Cold Stoic, Vero, Aurelius); wood-body Siberian Pro 1-year only
Plastic-body tubs (Cold Stoic 2.0, Cold Stoic 3.0, Vero, Aurelius) carry a 5-year limited warranty for residential use, except the chiller at 1 year; the wood-body Siberian Pro gets just 1 year on everything. An extended chiller warranty bought within 364 days of shipment brings chiller coverage to 5 years total. Claims go through help@renutherapy.com with proof of purchase, dated receipt and failure details.
Alternatives to Compare
Plunge
PoweredPlunge is the default powered pick for a reason: the widest lineup in the category, 37F performance off a normal 120V outlet, and constant promotions that knock $900 to $2,000 off. Never pay list; the sale is effectively permanent. The tradeoff is a 1-year standard warranty and enough owner reports of chiller failures and connection leaks that you should plan placement and budget for maintenance. Right for the mainstream buyer who wants a supported name, app control, and financing. Wrong for anyone who expects warranty depth to match a $5,000 to $8,000 price.
Sun Home Saunas
PoweredThe 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.
Chilly GOAT
PoweredChilly GOAT is Master Spas building cold tubs under Michael Phelps' name, and the useful part is not the endorsement. It is that the full ladder is published, from $995 for a tub with no chiller to $14,995 for the Valaris contrast unit. In a category where most brands make you ask, that is worth something. The Valaris is the interesting product: hot to 104°F on one side, cold to 40°F on the other, which is contrast therapy in one footprint rather than two. Warranty terms are not published, so that is the thing to get in writing.
Edge Theory Labs
PortableYou 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.

Methodology
Brand verdicts are based on buyer fit by lane, chiller and water care reality, support path, price pressure, and the failures that tend to show up after delivery. A strong reply from a manufacturer can improve factual clarity, but it does not improve placement.
If warranty language is short, the chiller is a known weak point, or support coverage is thin, we would rather say that plainly than hide it behind marketing copy.
