Sunray Rockledge Sauna Review: 2-Person Indoor Traditional Sauna

Short answer: the Sunray Rockledge is a compact 2-person indoor traditional sauna in Canadian hemlock, with a 4.5 kW heater and stones, a cultured stone back wall, Bluetooth audio and color lighting. It needs a dedicated 240V, 20 amp circuit, not a regular outlet. It's a good fit for a couple who want real hot-rock heat in a small room, but it's out of stock right now, so check the Sunray Rockledge product page or see the in-stock alternatives below.

Sunray Rockledge at a glance

What you get

• 4.5 kW electric heater with stones and an integrated digital keypad for temperature, time, lights and heater intensity
• Cultured stone back wall and solid wood floor
• Bluetooth audio
• Ceiling color (chromotherapy) lighting with 7 colors, plus ambient lighting
• Built-in backrest
• Sand timer and hygrometer to track session time, heat and humidity
• Bucket and ladle for pouring water on the stones

Heater, heat-up and steam

The Rockledge heats air and stones, so it's a true traditional sauna rather than an infrared cabin. The listing quotes 175°F to 195°F and about 30 to 45 minutes to heat up, which is normal for a stove sauna: you switch it on before you want to use it. Pour a ladle of water over the stones for a burst of steam when you want more humidity. For safe ranges and how long to stay in, see our sauna temperature guide.

Heater note: Sunray's data sheet lists a 4.5 kW Harvia heater, while one supplier note mentions a 3 kW heater. The 4.5 kW figure appears on both the data sheet and the product listing, but confirm the rating on the heater label before your electrician sizes the circuit.

Size and where it fits

At 59" wide, 42" deep and 75" tall outside, the Rockledge fits a spare room corner, basement or home gym. Inside you get 54" x 38" x 69", which seats two adults side by side. Measure ceiling height, doorways and the delivery path before you order. If you're torn between sizes, read What Size Sauna Do I Need?

Power, installation and running cost

• Circuit: the data sheet calls for a 240V, 20 amp dedicated power supply (the product page lists it as 220V, 20 amp, the same class of circuit). It won't run from a standard 120V outlet, so plan on an electrician.
• Location: indoor use, on a level floor that can take about 600 lb plus occupants.
• Running cost: at full power the 4.5 kW heater uses about 4.5 kWh per hour. At the 2026 US average of roughly 18¢ per kWh (EIA), that's about 80¢ per hour of heating. The thermostat cycles the heater once the room is hot, so a typical session costs less.

Pros

• Real hot-rock heat and steam in a compact 2-person footprint
• Cultured stone wall and glass front give it a spa look
• Bluetooth, color lighting, sand timer and hygrometer included
• 7-year structural warranty

Cons

• Needs a dedicated 240V, 20 amp circuit
• Out of stock at the time of writing
• 30 to 45 minutes of preheating, unlike infrared cabins
• Only 1 year on electronics and the heater

Warranty and data sheet

Sunray lists 7 years on the structure and 1 year each on electronics and the heater. You can download the Sunray Rockledge data sheet (PDF), and other Sunray manuals are on our Sunray owner's manuals page.

In-stock alternatives

Prices were checked on November 4, 2026 and can change, so the product page always has the current price.

• Sunray Baldwin: the same brand in a plain hemlock cabin with a smaller 3 kW heater, at a lower price. It runs a little cooler.
• Golden Designs Sundsvall: the step up, with a 6 kW stove, red cedar interior, Bluetooth and color lighting. It's taller and needs a 30 amp stove circuit plus a 120V outlet.

Final thoughts

The Sunray Rockledge packs real traditional heat, a stone feature wall and a long structural warranty into a small 2-person cabin. Plan for a dedicated 240V, 20 amp circuit and about 45 minutes of preheat. While it's out of stock, the Baldwin is the budget alternative and the Sundsvall the premium one.
