A home sauna is a big purchase, and the first thing most people want to know is the price, then what happens if it is not right. We set the Relaxe Caldera Two Person next to the two-person model from Sunlighten, Clearlight, Sun Home and SaunaBox, on price, home trial, delivery, setup, red light and power.

Sun Home accepts returns within 30 days, for unopened packaging only, and keeps a 25% restocking fee plus shipping both ways, even on a free shipping order.

What you get with the Relaxe Caldera

The Caldera is an infrared sauna with a full-body red light panel included. The temperature runs from 64 to 149 °F and the timer from 0 to 90 minutes, and some owners switch on the red light panel while the sauna heats. The Two Person measures 47 by 43 by 75 inches.

A Relaxe infrared sauna lit from inside, with wooden slat walls and a glowing heater beneath the bench — The Caldera sauna, from the Relaxe product page.

Relaxe lists a three-year warranty with technician service. The product page covers heaters, electronics and wood panels, with free replacement parts and U.S.-based technician support.

Check the power first

The Two Person needs a dedicated 120 V, 20 A circuit. Sunlighten lists the same, Clearlight lists a 120 V, 20 A outlet, Sun Home lists a dedicated 30 A circuit and SaunaBox lists a standard household outlet. Confirm the requirement for your home on the product page and ask an electrician if you are unsure.

The four competing saunas

Here is what each brand’s own pages say about its two-person sauna.

Sunlighten mPulse Believe

No price published. Sunlighten asks you to request a quote.

A two-person cabin with 15 heaters: 6 far-infrared, 5 mid-infrared and 4 red and near-infrared. Sunlighten’s PulseIQ system delivers each wavelength separately, and the sauna comes with preset programs and a companion app. It is listed at 51.7 by 47.6 by 79 inches, needs a dedicated 120 V, 20 A circuit, and comes in basswood or eucalyptus. Sunlighten’s warranty page lists 5 to 7 years on cabinetry and heaters and 1 year on glass doors and audio.

Where Relaxe differs: a price you can see, 365 days at home, and delivery in 2 to 5 days.

Clearlight Sanctuary 2

No price published. Clearlight asks you to request a quote.

A two-person full spectrum sauna with two 500 W True Wave heaters on the front wall and far infrared heaters on the back and side walls, behind the calves and under the floor. It has digital controls, a smartphone app, Bluetooth audio and chromotherapy lighting, comes in mahogany or basswood, and is listed at 51 3/4 by 47 3/4 by 77 inches. It plugs into a 120 V, 20 A outlet. Clearlight lists a limited lifetime warranty for residential use, covering the heaters, controls, electrical and wood, and the included audio system.

A two-person indoor sauna in Canadian hemlock, with 6 far-infrared and 2 full-spectrum heaters, red light therapy included and a top temperature of 165 °F. It needs a dedicated 30 A circuit with a NEMA L5-30 outlet. Sun Home lists a limited lifetime warranty and free U.S. shipping. Standard delivery is curbside freight with lift gate service, and carrying it indoors, uncrating and assembly are the owner’s job.

Where Relaxe differs: about $5,100 less, 365 days at home instead of 30, and no restocking fee.

SaunaBox Solara 2-Person

$4,499 on SaunaBox’s site, listed as down from $5,500

A two-person cabin in Canadian hemlock with full-body 660 nm and 850 nm red light therapy, dual Bluetooth speakers and adjustable chromotherapy. SaunaBox says it runs off a standard household outlet. It ships in two cartons, about 355 lb in total, delivered curbside, and SaunaBox lists a 30-day return guarantee for unused items, with a return fee deducted from the refund ($500 for freight items).

Where Relaxe differs: 365 days at home instead of 30, no restocking fee, and a three-year warranty with technician service, against one or two years on SaunaBox’s pages.

Questions before you buy

Why are there no Sunlighten or Clearlight prices on this page?

Neither Sunlighten nor Clearlight publishes a price for its two-person sauna. Their product pages direct you to request pricing, so we have not put a figure on this page.

Why these four brands?

They are four well-known brands that sell a two-person home infrared sauna in the U.S. We compared each brand’s two-person model with the Relaxe Two Person.

How long do I get to try the Relaxe sauna?

365 days at home. You can return the sauna for a full refund of the sauna price with no restocking fees, and you cover the return shipping.

How hard is it to put together?

It comes flat-packed in three to four labelled boxes with a screw kit and an installation guide, and Relaxe says two people can assemble it with basic tools. If you get stuck, owners say support answers fast and sends assembly videos.

Do I need an electrician?

The Relaxe Two Person lists a dedicated 120 V, 20 A circuit. Sunlighten lists the same, Clearlight lists a 120 V, 20 A outlet, Sun Home lists a dedicated 30 A circuit and SaunaBox lists a standard household outlet. Owners describe different setups at home, so check the requirement on the product page and ask an electrician if you are unsure.

What if a part arrives damaged?

It can happen with a heavy product shipped in several boxes. Several owners who reported a damaged part describe a quick replacement. Relaxe also lists a three-year warranty with technician service and free replacement parts. The product page does not name the red light panel in the coverage list, so read the warranty terms.

Does this page make health claims?

No. This page compares prices, features and terms and quotes what owners say about owning the sauna. It does not claim that a sauna or a red light panel treats or prevents any condition. If you have a medical condition, talk to your doctor before you start using a sauna.
