What ships in the SunRay Charleston crate
Published contents for the SunRay Charleston run to four component groups; three further items are needed to finish the build. That second number is the one that moves a budget, because each of those items is priced separately and none of them appear beside the from $4,598 figure on the listing.
What the SunRay Charleston kit includes
- Pre-built wall panels that bolt together
- 6.0kW Harvia electric heater, included
- Benches and interior fittings
- Glass door
What the SunRay Charleston kit does not include
Every item below is a real cost on top of the from $4,598 kit price. The SunRay Charleston is one of the few kits that does ship a heater, so the largest of these lines is already covered.
- The 240V circuit to the sauna location
- Any flooring, levelling or drainage the room needs
- Ventilation work, where the room does not already have it
What heater the SunRay Charleston needs
This is one of only two kits in the catalog with a heater in the box — a 6.0kW Harvia unit matched by SunRay to the room it ships with. That removes the sizing question entirely, which is a genuine advantage for a first-time buyer. You still need the 240V supply run to it.
For how heater sizing works across every kit in this catalog, including which models ship a heater and which leave it to you, see our sauna kit heater compatibility guide.
What the SunRay Charleston costs to finish
The SunRay Charleston kit is listed at from $4,598. The lines below are the rest of the project, and they are budget guidance rather than quotes. On this kit the widest band is 240V electrical run, so that is the line to price properly before committing to the rest.
| Line | Budget | What drives it |
|---|---|---|
| SunRay Charleston kit | From $4,598 | The structure as listed at Topture. |
| Heater | $0 | Included. The 6.0kW Harvia unit ships with the kit, which is unusual at this price. |
| 240V electrical run | $500–$2,500 | Installed, and highly site-dependent. Trenching distance and panel capacity drive it. Your authority having jurisdiction sets what is required. |
Our buying guide breaks the completed-project arithmetic down across every format, and the kit electrical requirements guide covers what drives the widest line on this table.
Assembling the SunRay Charleston
Panelised kits bolt together, so this is the least demanding build in the catalog. Typically a few hours for two people rather than a weekend, and the electrical connection is the part that needs a qualified person.
Base and siting requirements differ by format and by weight. Our kit foundation requirements guide covers what each format needs underneath it.
SunRay Charleston pros, cons and buying considerations
What the SunRay Charleston does well
- 6kW Harvia heater, stones, and accessories included — true all-in-one pricing
- 2–4 hour panelized assembly — the fastest build on this list
- Real traditional steam (water on stones) at up to 180°F
- ETL safety certified; tempered glass door and panels
- Complete accessory set: cask, ladle, hygrometer, timer, lighting
Where the SunRay Charleston compromises
- Fixed dimensions — can't adapt to odd spaces like pre-cut kits
- Hemlock lacks cedar's aroma
- 180°F ceiling is slightly below the hottest outdoor units
What to weigh before ordering the SunRay Charleston
- Needs a dedicated 240V circuit installed by an electrician — the one trade you can't skip
- Fixed footprint — confirm room and doorway clearances before ordering
- Hemlock is paler and plainer than cedar — aesthetic preference, not quality difference
- Indoor placement needs a moisture-tolerant floor (tile, concrete, vinyl — not carpet)
Who the SunRay Charleston suits
Buy the SunRay Charleston if
- Buyers who want the heater sizing decision made for them
- Spare rooms and basements with a rectangular space and a nearby panel
- Anyone who wants the shortest path from delivery to first session
Skip the SunRay Charleston if
- Awkward room shapes, where a pre-cut kit fits and a fixed panel footprint does not
- Buyers who want cedar rather than the panel kit's specification
- Anyone wanting a larger room than the fixed footprint provides

SunRay Charleston questions
Does the SunRay Charleston include a heater?
Yes. It ships with a 6.0kW Harvia electric heater matched to the room, which makes it one of only two kits in this catalog that does not send you shopping for one separately. That removes both the sizing decision and roughly $900–$2,500 from the project budget.
How many people does the SunRay Charleston seat?
The SunRay Charleston is specified as a four-person room, with two of those able to recline. As with every capacity rating, four sitting upright is the ceiling rather than the comfortable figure. For two people who want to lie down, it is genuinely well suited.
Do I still need an electrician for a kit with the heater included?
Yes. The heater being in the box does not supply the circuit that feeds it. A 240V run to the sauna location is still required, and what that run must satisfy is set by your local authority having jurisdiction. Budget it as a separate line even though the heater itself is free of charge.
