Why Relaxe comes out ahead

A price you can see.

The Relaxe Caldera Two Person is $5,499 on its product page right now. Clearlight does not publish a price for the Sanctuary 2. Its page says “Get Pricing” and shows a “Save $400” offer without the price it comes off, so you have to ask for a quote before you can compare. With Relaxe, you can tell whether it fits your budget in the time it takes to read this page. The price is part of the current offer, so check the product page for today’s terms.

A full year to decide.

Relaxe gives you 365 days at home. If the sauna is not right for you, you can return it for a full refund of the sauna price, with no restocking fees. You pay the return shipping, so read the terms on the product page. Clearlight’s policy accepts returns within 30 business days of receipt, with the customer paying return shipping, and refunds the purchase price minus any original shipping charges and a 25% restocking charge.

Delivered in days, built by two people.

Relaxe lists free shipping and 2 to 5 day U.S. delivery. It comes flat-packed in three to four labelled boxes, with a screw kit and an installation guide, and Relaxe says two people can put it together with basic tools. Clearlight’s policy says its saunas ship as boxes on a pallet, with lift gate service by delivery appointment, and that an adult must be there to sign.

A smaller footprint.

The Two Person measures 47 by 43 by 75 inches and weighs 340 pounds. The Sanctuary 2 is listed at 51 3/4 by 47 3/4 by 77 inches and 450 pounds, so it takes up more room.

The red light is already in the box.

Every Caldera comes with a full-body red light therapy panel in the same order: 180 LEDs, red light at 660 nm and near-infrared at 850 nm, plus protective glasses. Relaxe lists the panel as an $899 value. Clearlight lists a red light therapy upgrade as an add-on.

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.

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. Clearlight lists a 120 V, 20 A outlet for the Sanctuary 2. Confirm the requirement for your home on the product page and ask an electrician if you are unsure.

The Clearlight Sanctuary 2

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.

Where Relaxe differs: a price you can see, 365 days at home, a red light panel included, and a smaller and lighter cabin.

What it costs

From $3,999, with three sizes

Questions before you buy

Why is there no Clearlight price on this page?

Clearlight does not publish a price for the Sanctuary 2. Its product page directs you to request pricing, so we have not put a figure on this page.

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, and Clearlight lists a 120 V, 20 A outlet for the Sanctuary 2. 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.
