Our verdict

Renu Therapy suits buyers in the US who want a cold plunge and an infrared sauna from the same maker, with its largest unit seating 8 people. The $5,739 starting price is the trade-off to weigh, and finance helps soften it.

Pros and cons

Pros

  • Maximum seating of 8 people suits a shared recovery room rather than a solo cabin.
  • Plug and play hardware plus included delivery removes installation friction from the purchase.
  • Warranty of 5 years sits above the category median of 4 years.
  • Finance is offered, which spreads a $5,739 starting price.
  • The range covers cold plunge, sauna and infrared sauna, so cold plunge and infrared shoppers are served by one maker.

Cons

  • Starting price of $5,739 ranks 21 of 25, which puts it among the costlier entries in this group.
  • Sales cover US only, so buyers outside that market have no local service base.
  • Warranty of 5 years ranks 8 of 18, behind the longest cover on offer.
  • The range is cold plunge, sauna and infrared sauna, narrower than Lay-Z-Spa at hot tub, inflatable hot tub and cold plunge for anyone who also wants a hot tub.

Who it suits

  • Buyers in the US who want a cold plunge and an infrared sauna from the same maker.
  • Households or small recovery groups who want a roomy cabin, since the largest unit seats 8 people.
  • Shoppers who would rather spread a $5,739 outlay than pay it up front, since finance is offered.

Who should look elsewhere

  • Lay-Z-Spa buyers, who want hot tub, inflatable hot tub and cold plunge and a hot tub alongside any cold option.
  • Vellgus buyers, whose infrared sauna range suits infrared-only shopping.
  • Shoppers on a tight budget, since the $5,739 entry price ranks 21 of 25.

Core features

The units are built around an electric heater rated at 1.013 kW and are sold as plug and play, so a specialist installer sits outside the purchase. Delivery is included rather than charged on top, which matters when a sauna or cold plunge is going into a garage, basement or spare room. Capacity is the number worth checking first. The largest units seat 8 people, so this is a range built for a shared recovery space rather than a single-user cabin. If you are working through spec sheets, that seat count separates a Renu Therapy unit from most of the saunas and cold plunges nearby on this site. Cover runs 5 years, longer than the median warranty across this group, and it applies to the heater as well as the cabin on the units listed. Finance is offered as well, which matters for buyers who would rather spread the outlay than pay the whole sum up front. That changes the monthly commitment rather than the headline price.

How it compares on our data

Price is where Renu Therapy gives ground and capacity is where it gains. On starting price the brand ranks 21 of 25, which places it among the costlier entries in the saunas and cold plunge group. Buyers on a tight budget have fewer options here. Capacity turns the picture around. On maximum seats Renu Therapy ranks 4 of 21, so the roomy end of the range sits close to the front of the field. Shoppers looking for a shared unit will find few rivals with more space inside the cabin. Warranty falls between the two. The rank of 8 of 18 on warranty years is a middle position, with longer cover at one end of this group and shorter cover at the other. Read the warranty as solid rather than as the reason to choose. Taken together, the ranking says this plainly: you pay more here to get more room, not to save.

The company behind it

The company trades as Renu Therapy, is headquartered in the US, and was founded in 2020. That makes it a relatively young business in a category where longer-established names carry most of the recognition, so you are dealing with a newer legal entity rather than an inherited workshop. Support runs through email, phone and help centre. Email and phone reach the team directly, and a help centre holds setup guidance for owners who would rather look up the steps than call. That mix suits buyers working from the manual and buyers who want a person on the line when something stops working. In a category where heaters, seals and cabins all need attention over time, these company details matter as much as the spec sheet. A named legal entity, a published warranty and a stated support roster give you somewhere to take a problem, which is more than a bare contact form.

Frequently asked questions

How much does a Renu Therapy unit cost?+

Units start at $5,739. That figure is the entry price for the range, and delivery is included at that price rather than added later, so the number you see sits close to the number you pay. Finance is offered if you would rather spread the cost.

What is included with the price?+

Delivery is included with the unit, and the hardware is sold as plug and play, so there is no separate install line to budget for. The heater is rated at 1.013 kW. Check that your circuit and floor space suit the unit before ordering.

Can I pay for a Renu Therapy unit in instalments?+

Finance is offered, so the $5,739 entry price can be spread rather than paid up front. Buyers chasing the roomiest units rather than the cheapest should run the numbers on the plan, since spreading a larger figure still leaves a bigger monthly payment.

Where does Renu Therapy sell?+

Sales cover US, and the company is headquartered in the US. Buyers inside that market can expect included delivery and local support. Anyone outside it is buying without a nearby service base.

How long is the warranty?+

The warranty runs 5 years. The median across this group is 4 years, so Renu Therapy sits above the middle, although longer cover exists further up the ranking.

How many people fit in a Renu Therapy unit?+

The largest units seat 8 people, and on that measure Renu Therapy ranks 4 of 21 brands, which is near the front of the field. The smaller cabins in the range suit solo use.

What kinds of units does Renu Therapy make?+

The range covers cold plunge, sauna and infrared sauna. Bast Sauna covers sauna and cold plunge and Lay-Z-Spa covers hot tub, inflatable hot tub and cold plunge, so a shopper who wants a hot tub alongside a cold option has more choice elsewhere.

How do I get help after delivery?+

Support runs on email, phone and help centre. Email and phone give you a direct line to the team, and the help centre covers setup steps for owners who would rather work through the guide themselves.
