918 sq in
Five Cooking Styles, One Grill
918 square inches across the main grate and upper racks let you grill, smoke, roast, bake, and slow-cook without switching appliances or running out of room.
140°F–800°F
Cold Smoke to High-Heat Sear
The temperature range runs from 140°F for low-and-slow smoking up to 800°F with the adjustable Flame Broiler engaged — one grill covers both ends of the cooking spectrum.
Patented
Built-In Cold Smoker
A dedicated cold-smoking system infuses delicate foods like cheese, seafood, and charcuterie with real smoke flavor without exposing them to direct heat.
3 Probes
Digital Control with WiFi
A weatherproof touchscreen control center with WiFi connectivity and three meat probes lets you monitor internal food temperature and shift to smoke mode automatically once it's reached.
28 lb
Large-Capacity Side Hopper
A 28-pound side hopper with an accent light keeps pellets loaded for long cooks, so you're not refilling mid-smoke on an all-day brisket.
304 SS
Insulated, Double-Lined Hood
The double-lined hood and oven-grade braided fire-rope gasket seal in heat, while all-304 stainless steel construction stands up to humid climates and coastal air.

Three Hanger Hooks for Sausage, Jerky, and Vertical Smoking
Three integrated hanger hooks let you suspend meat directly over the heat source for even cooking and smoke distribution — useful for sausages, jerky, or anything that benefits from hanging rather than resting flat on a grate. A removable grease tray and fan-forced convection system round out the cooking setup, helping the unit hold steady temperatures like a true outdoor oven.
Sized to Drop Into a 38" x 22" x 17" Cutout
The SUNPLT40 is built to drop into a 38-inch by 22-inch by 17-inch cutout, with an overall footprint of 40 inches wide by roughly 30 1/8 inches deep by 31 inches tall. At 257 lb, plan for a multi-person lift or mechanical assistance during installation. Measure your island opening against these numbers before you order so the unit seats flush on install day.
Who It's For — The Deck & Den Take
▶
The Deck & Den Take — This is the appliance to pick if you want a grill, a smoker, and an oven without three separate units taking up island space. The cold smoker is the real differentiator here — most pellet grills can hot-smoke, but few can run a true cold smoke for cheese or cured items without ruining them with heat. If you're coming from a basic gas grill, give yourself time with the touchscreen controls; the learning curve is worth it for the consistency.
-
Cooks who want true cold-smoking capability for cheese, seafood, and charcuterie, not just hot smoke.
-
Anyone replacing a separate grill-plus-smoker setup with one built-in unit.
-
Outdoor kitchens with the cutout space and budget for a serious, centerpiece-level appliance.
-
Hosts who want WiFi monitoring and meat probes for long, unattended cooks like brisket or pulled pork.
-
Anyone who wants vertical hanging capability for sausage, jerky, or specialty smoked items.

Frequently Asked Questions
▶
What's the difference between this and a regular pellet grill?
▶
The built-in cold smoker is the main differentiator — it lets you smoke delicate foods like cheese and seafood without applying direct heat, which most pellet grills can't do well, if at all.
What temperature range does it cover?
▶
140°F to 800°F, covering everything from cold smoking and low-and-slow barbecue to high-heat searing with the adjustable Flame Broiler.
How big is the cooking area?
▶
918 square inches total — 527 square inches on the main grate plus 391 square inches across the upper racks.
What cutout size do I need for installation?
▶
The grill requires a 38 in. wide by 22 in. deep by 17 in. tall cutout. Confirm your island's opening against these dimensions before ordering.
What are the hanger hooks for?
▶
The three integrated hanger hooks let you suspend sausages, jerky, or other foods directly over the heat source for even cooking and smoke exposure, instead of laying everything flat on a grate.
Does it require electricity as well as pellets?
▶
Yes — wood pellets are the fuel source, but the auger feed system, igniter, fan, and digital controls all run on electricity, so the unit needs a power connection in addition to its pellet supply.
How does the meat probe system work?
▶
Three integrated meat probes monitor internal food temperature, and the grill can automatically shift into a holding or smoke mode once your target temperature is reached.
What's covered under warranty?
▶
Sunstone covers the 304 stainless steel structure under a limited lifetime warranty, with separate terms for other components such as valves, knobs, and electronics. Full details are in the warranty guide above.
How much does it weigh?
▶
257 lb on its own — useful to know when planning crane support or a multi-person lift for your island build.
What if it doesn't fit my island?
▶
If the unit doesn't fit your cutout or isn't right for your setup, it's covered by Deck & Den's 45-day return policy — just contact us before sending it back.
