Shipping & Delivery Information

Free Curbside Delivery

Curbside Delivery ships via Freight to the 48 contiguous states. The freight carrier will contact you 24 to 48 hours prior to delivery to set a delivery day and time Monday-Friday, with a 4-hour open window.

They won’t deliver without speaking to you first. **Shipping times are only approximate, and can change depending on environmental conditions, transit issues, and carrier’s availability. Last minute appointments can occur, and it’s out of our hands since the delivery process is managed by the carrier’s. The sauna will be delivered in 1 box or more, depending on the model. All boxes will be strapped to a pallet. All saunas are delivered in a 53-foot semi-truck with a single driver, who will unload the pallet to your curbside or driveway only. Any delivery questions or issues (remote areas, long driveways, large and low hanging trees, apartment complex, stairs, etc.) should be addressed with us prior to shipping your sauna.

Once the driver has unloaded the sauna, we ask that you immediately inspect the boxes for any damage. Please indicate any minor scratches, indentations, or scuff marks to the outside of the boxes on the delivery receipt. You do not need to open the boxes to inspect the sauna. The freight company will deliver your sauna to a carport or first-floor entryway. Please check the box dimensions and ensure it will fit through your doorway. Assembly on these saunas are surprisingly easy and can take between 30-45 minutes, depending on the sauna. Assembly instructions are included with the saunas.

Indoor Traditional Sauna

SunRay Charleston 4-Person Indoor Traditional Sauna

The Charleston is as wide across the front as SunRay's indoor cabins get — 71 inches — on 63 inches of depth and 80 of height, with 67 inches of interior width behind the door. SunRay describe the two-tier double-bench design as offering flexible seating — comfortably accommodating four bathers, or letting two people stretch out and fully unwind. A 6.0 kW Harvia electric heater supplies the heat.

It is built from beautiful natural Canadian Cedar, which SunRay say combines lasting durability with timeless elegance and creates a warm, inviting atmosphere that enhances every session. Interior dome lighting, an integrated ventilation system, a thermo-hygrometer and an upgraded door handle are part of the specification.

The Build

Cedar Across A 71-Inch Front

Where SunRay's other four-person cabin goes deep, the Charleston goes wide. Four specification choices follow from that: the cedar it is cut from, the double bench that fits inside it, the 6 kW heater that fills it, and the hardware on the door.

🌲

Beautiful Natural Canadian Cedar

SunRay's claim for the cedar is durability alongside what they call timeless elegance, with an interior that creates a warm, inviting atmosphere. Cedar is the TN half of SunRay's indoor range; the SN cabins are hemlock.

Two-Tier Double Bench

SunRay describe the seating as spacious and flexible: four bathers seated, or two stretched out. Their feature bullet for the layout reads 2 Tiered Bench Seating.

6.0 kW Harvia Heater

SunRay say the Harvia unit is engineered to produce temperatures up to 180°F, creating what they describe as a deep, invigorating heat. Draw is 6,000 watts on a 30-amp dedicated outlet.

Upgraded Door Handle

The Charleston's feature list names an upgraded door handle — the same fitting SunRay call out on the Aston and Hampton, and one they leave off the hemlock cabins entirely.

Four Details That Make The Charleston

Seating

A Bench Arrangement That Works Two Ways

SunRay's description of the Charleston's interior is unusually direct about the trade-off: the spacious two-tier, double-bench design offers flexible seating arrangements, comfortably accommodating four bathers or allowing two individuals to stretch out and fully unwind. The room measures 67 inches wide by 59 deep with a 72-inch ceiling. Ergonomic backrests are included.

Materials

Cedar, And What SunRay Say About It

The Charleston is cut from beautiful natural Canadian Cedar. SunRay's claim is that the cedar interior combines lasting durability with timeless elegance, creating a warm and inviting atmosphere that enhances every session. SunRay's four-person hemlock cabin, the Tiburon, carries the same 6 kW Harvia and the same two-tier double bench, so the species is the difference SunRay themselves put between them.

Heat And Steam

6 Kilowatts, And 180 Degrees Behind It

SunRay describe the Charleston as powered by a 6.0 kW Harvia electric heater, and state that Harvia heaters are engineered to produce temperatures up to 180°F. The included water cask and spoon let you add water to the heater stones for steam and set the humidity where you want it. Power draw is 6,000 watts at 220V through a 30-amp dedicated outlet.

Frequently Asked Questions

Four. SunRay describe the two-tier double-bench design as comfortably accommodating four bathers, or allowing two individuals to stretch out. The interior is 67" W × 59" D × 72" H, with 59 inches of depth behind the door.

Both seat four on a double bench and both run a 6.0 kW Harvia heater on a 30-amp circuit. After that they diverge. The Charleston is Canadian cedar, in a cabin 71 inches wide by 63 deep, weighing 510 lbs, with an upgraded door handle and a cask and spoon in the box. The Tiburon is Canadian hemlock, at 63 wide by 69 deep, 599 lbs, with a cup holder. Wide room, take the Charleston. Deep room, take the Tiburon.

71" wide × 63" deep × 80" tall. Both the width and the height sit at the top of SunRay's indoor range, so check the wall run and the ceiling before ordering, and leave clearance for the door.

Yes. The 6.0 kW Harvia heater comes with the sauna, along with 2 tiered bench seating, an ergonomic backrest, a ventilation system, a cask and spoon, a hygrometer and sand timer, and an upgraded door handle. SunRay refer to adding water to the heater stones but publish no stone quantity.

SunRay state the Charleston's Harvia heater is engineered to produce temperatures up to 180°F. That is their figure for this cabin specifically — they publish a lower maximum for their hemlock four-seater with the same rated heater, so we quote each page's own number and do not average the two.

They call it beautiful natural Canadian Cedar and say the cedar interior combines lasting durability with timeless elegance, creating a warm and inviting atmosphere that enhances every session. That is their claim in full — no colour, grain or scent detail is published for either species, so we add none. The wood is Canadian, and SunRay do not publish where the cabinets themselves are built.

SunRay specify 220V, 50/60Hz on a dedicated 30-amp outlet, with the heater drawing 6,000 watts. Our Specifications tab adds 240V for the sauna heater and 120V for the interior and exterior lights. Sauna heater wiring should be run by a licensed electrician.

510 lbs is SunRay's published product weight; no separate shipping weight is given for the Charleston. Free curbside delivery via freight to the 48 contiguous states, with free delivery damage insurance included. The freight carrier contacts you 24 to 48 hours ahead to set a day and time Monday through Friday inside a 4-hour window, and will not deliver without speaking to you first. The sauna arrives strapped to a pallet on a 53-foot semi-truck with a single driver, who unloads to your curbside or driveway only. Raise anything unusual about your access — long driveway, low branches, stairs, apartment complex — with us before the sauna ships. When the driver unloads, inspect the boxes and note any scratches, dents, or scuff marks on the delivery receipt. You do not need to open the boxes to do that.

SunRay cover the sauna with what they call a 7/1 warranty: 7 years on the structure — the wooden cabin and all glass parts — and 1 year on all parts including electronics and the heater. Claims require your receipt, and SunRay ask that the registration card be returned. Recovery For Athletes is an authorized SunRay dealer. Full terms are in the Warranty tab.

SunRay state that their saunas carry CE, CETL, ETL and RoHS marks. SunRay's Charleston page carries no model-specific certification claim, so that company-level statement is all we will repeat here. Ask us if an inspector needs a listing file number and we will request it.

Very Satisfied Customer

— Gene S. (5/5)

Q&A

Does the heater have a plug or will it need to be hardwired? Can the heater be upgraded to 8kW? Thanks.: This sauna comes with a power cord attached to the heater. The power cord does not have a plug. It is designed to be hard-wired into a junction box or you can put a plug on the end of the power cord. You may be able to replace the heater with an 8kw heater. The 8kw would need to be purchased separately.
