Sun Home Eclipse vs Solstice

The short version: the Solstice is Sun Home's straightforward far-infrared cabin — eight to ten wall-mounted panels, a published 140 °F, kiln-dried eucalyptus and a dedicated 20 A circuit, in one-, two-, three- and four-person sizes. The Eclipse keeps the far infrared and adds full-spectrum heaters, built-in red light, a heated floor panel and a calf heater, in two- and four-person sizes, on a dedicated 30 A circuit. If you want infrared heat and nothing else, the Solstice is the simpler buy. If red light and full spectrum are the reason you are shopping, it is the Eclipse.

Side by side

What the Eclipse adds

Sun Home describes the Eclipse as three walls of far-infrared panels, adjustable full-spectrum heaters behind the backrests, a heated floor panel and a dedicated calf heater, plus built-in red light therapy towers. The Solstice is the focused version: eight to ten wall-mounted far-infrared panels with no floor unit, plus chromotherapy lighting and Bluetooth audio. Full spectrum means near and mid infrared as well as far — our full-spectrum vs far-infrared page explains what that changes, and red light vs infrared sauna what the red light adds. Sun Home's Eclipse pages do not publish the wavelengths or irradiance of its red light.

The circuit is the practical difference

The one-, two- and three-person Solstice each run on a dedicated 120 V, 20 A circuit with a NEMA 5-20 outlet; the four-person needs 240 V on a NEMA 6-20. Sun Home adds a detail worth passing to your electrician: use a standard breaker, because GFCI and AFCI breakers trip during normal operation. The 10-foot cord leaves the back-left of the roof, so plan the outlet on that side. The two-person Eclipse stays at 120 V but moves to a 30 A circuit and a NEMA L5-30 twist-lock outlet; the four-person is 240 V on an L6-30. A 20 A circuit is a common job; a 30 A twist-lock is a bigger one, and Sun Home asks Eclipse buyers to book the electrician before delivery day.

Wood and heat

The Solstice is built from kiln-dried eucalyptus with low-VOC materials, and Sun Home publishes a maximum of 140 °F. The Eclipse is Canadian hemlock, and its product pages do not state a maximum. Sun Home's care advice for the Solstice is the advice for any infrared cabin: dry heat is the point, so keep water, harsh cleaners and abrasives off the wood — moisture and pest damage sit outside the warranty. Both assemble indoors from panels; the Eclipse arrives crated, at 700 to 1,100 lb depending on size.

Where the warranties differ

The headline terms are the same length. The Solstice has seven years on cabinetry and heaters; the Eclipse has a limited lifetime warranty that Sun Home's terms say applies for up to seven years, for residential use. Both give controls three years and glass doors and audio one. The difference is what happens when something fails. The Eclipse terms include parts, labor and shipping for the first 90 days from delivery, under general terms that list the Eclipse, Pod, Luminar and traditional saunas. The Equinox and Solstice section sets out the durations above for residential use — and five years on cabinetry and heaters for commercial use — but does not say how labor is handled, and those general terms do not list either model. Ask Sun Home what labor cover comes with a Solstice before you buy. We set these against other brands in sauna and cold plunge warranties compared.

Which to choose

• The Solstice, if far infrared is what you want, you need a one- or three-person size, or a 20 A circuit is easier to add than a 30 A twist-lock.
• The Eclipse, if you want full-spectrum heaters, built-in red light and a heated floor, and a 30 A circuit is feasible.

Alternatives you can buy today

Neither sells through Amazon. The first two picks below are cabins with red light built in, like the Eclipse; the other two are far-infrared cabins, like the Solstice — a two-to-three-person corner in solid red cedar and a four-person cabin with ten carbon panels. They are not Sun Home products, and none publishes EMF testing at stated distances.

Our honest position

These are two different cabins rather than a good and a better version of one. The Solstice does far infrared simply, in four sizes, on a 20 A circuit. The Eclipse does more — full spectrum, red light, a heated floor — on a bigger circuit, with 90 days of labor included. Ask Sun Home for the Eclipse's red light wavelengths before you buy. We earn nothing from either; our Solstice review and Eclipse review go further into each.
