Arteflame ONE20 — 20" Flat-Top Charcoal Grill

Overview

Big live-fire performance. Remarkably compact footprint.

The Arteflame ONE20 Complete Set brings the signature Arteflame cooking experience to patios and outdoor spaces where a larger grill may simply be more than you need.

At just 20 inches in diameter, the ONE20 provides more than 300 square inches of cooking surface, combining direct-over-fire grilling with a surrounding 1/4-inch solid carbon-steel cooktop.

The center grate can reach 1,000°F+ for high-heat searing, while the surrounding flat-top creates progressively cooler cooking zones as you move away from the fire.

That means one compact grill can handle far more than burgers and steaks.

Sear proteins over the center.

Cook vegetables, seafood, eggs, bacon, bread, and other foods on the surrounding flat-top.

Then, when dinner is finished, keep the live fire at the center of the evening.

The Complete Set adds the accessories that make the ONE20 more comfortable, versatile, and easier to maintain—including a center grate riser, 10" base riser, stainless-steel lid, vinyl cover, seasoning puck, and leather grilling apron.

Compact in size. Serious about live-fire cooking.

Why This Product Stands Out

The ONE20 proves that live-fire cooking does not require an oversized grill.

Its 20-inch footprint makes it easier to incorporate into smaller patios, courtyards, garden areas, and other outdoor environments where space matters.

But the compact dimensions do not eliminate the features that define the Arteflame experience.

At the center, direct flame provides temperatures exceeding 1,000°F.

Around it, the solid carbon-steel cooktop creates a broad flat-top cooking surface with naturally varying temperature zones.

That combination gives the ONE20 more versatility than its size might suggest.

You can sear at the center, cook farther outward, and use the perimeter for gentler heat or holding finished food.

The flat-top surface also opens the menu beyond traditional grilling.

Small ingredients stay on the cooking surface rather than falling through a grate, making the ONE20 suitable for everything from breakfast to seafood and vegetables.

For smaller outdoor environments, it offers a compelling combination of space efficiency, serious heat, broad cooking versatility, and distinctive design.

Specifications

Who This Is For

The Arteflame ONE20 Complete Set is ideal for buyers who want a genuine live-fire cooking experience without dedicating a large portion of their outdoor space to the grill.

It is particularly well suited for:

• Smaller patios
• Open-air courtyards
• Compact outdoor entertaining spaces
• Couples
• Smaller households
• Intimate gatherings
• Vacation properties
• Garden entertaining areas
• Secondary outdoor cooking spaces
• Buyers who want a more compact Arteflame

The ONE20 is especially appealing when the priorities are space efficiency, live-fire cooking, and versatility.

300+ Square Inches of Cooking Space

The 20" cooktop provides more than 300 square inches of cooking area.

That gives the ONE20 enough room for a varied meal while keeping the physical footprint compact.

Depending on the menu, you can prepare:

• Steaks
• Burgers
• Chops
• Seafood
• Vegetables
• Eggs
• Bacon
• Pancakes
• Bread
• Sandwiches
• Side dishes

For couples and smaller gatherings, that can be an ideal balance between capacity and space.

1,000°F+ Center Searing

The center grate provides direct access to the fire.

According to the supplied specifications, temperatures in this area can exceed 1,000°F.

That creates a high-heat zone for searing proteins before moving them onto the surrounding flat-top for continued cooking or finishing.

A typical cooking sequence might be:

Sear → Move Outward → Finish → Hold

All on the same compact grill.

Multiple Cooking Zones

The circular cooktop naturally develops a heat gradient.

Center: highest heat
Middle: everyday cooking
Outer edge: gentler cooking and warming

That gives you a simple way to manage temperature based largely on food placement rather than mechanical burner controls.

Compact Size. Broader Menu.

The solid carbon-steel cooktop gives the ONE20 an advantage over a conventional open-grate grill when cooking smaller or more delicate foods.

It can accommodate items such as:

• Eggs
• Bacon
• Vegetables
• Shrimp
• Fish
• Small ingredients
• Flatbreads
• Sandwiches

Those foods remain on the cooking surface instead of dropping through an open grate.

The ONE20 Complete Set

The Complete Set turns the compact ONE20 into a more fully equipped cooking station.

Center Grill Grate

Provides direct-over-fire cooking and high-temperature searing.

Center Grate Riser

Raises the grill grate farther from the fire, giving you another cooking position and greater flexibility over heat intensity.

10" Base Riser

Raises the compact ONE20 to provide a more comfortable standing cooking position.

This is especially useful because the grill's smaller proportions would otherwise place the cooking surface lower than many users prefer.

Stainless-Steel Lid

Provides a dedicated cover for the cooking area and can be used according to Arteflame's instructions during post-cooking shutdown.

Premium Vinyl Cover

Adds another layer of protection when the grill is not in use.

Allow the ONE20 to cool completely before covering.

Seasoning Puck

Helps establish and maintain the carbon-steel cooktop's seasoned surface.

Full Leather Grilling Apron

Provides useful protection while working around the live fire and hot cooking surfaces.

From Cooking to Fire

The ONE20 is not limited to preparing food.

After the meal, the live fire can remain the focal point.

That gives the grill a second role as a compact gathering feature—particularly appealing in smaller outdoor spaces where every major piece of equipment benefits from serving more than one purpose.

CORTEN Weathering Steel

The body is constructed from U.S. CORTEN weathering steel.

Its exterior is designed to develop a natural patina with outdoor exposure, giving the ONE20 the warm, evolving appearance associated with Arteflame.

That changing finish is part of the design rather than something that needs to be kept perfectly uniform.

Care & Maintenance

Treat the carbon-steel cooktop similarly to other seasoned carbon-steel cooking surfaces.

For routine care:

• Scrape remaining food residue from the cooktop after cooking.
• Maintain the seasoning according to Arteflame's instructions.
• Apply an appropriate light coating of cooking oil when needed.
• Use the included seasoning puck as directed.
• Remove cooled ash and debris regularly.
• Keep the CORTEN body and base free of unnecessary buildup.
• Clean stainless-steel components as recommended.
• Allow the grill and all accessories to cool completely before covering or handling.
• Follow Arteflame's current care instructions.

Important Placement & Fire Safety

The ONE20 burns real hardwood or lump charcoal.

Use it only in an appropriate outdoor environment with adequate ventilation and required clearances.

Always:

• Place the grill on a stable, suitable, non-combustible surface.
• Maintain required distance from combustible materials.
• Follow local fire restrictions and regulations.
• Never use the grill in an enclosed or inadequately ventilated area.
• Never leave an active fire unattended.
• Keep children and pets away from hot surfaces.
• Allow all components to cool completely before handling or covering.
• Follow Arteflame's current operating and installation instructions.

A compact footprint does not reduce the need for proper fire clearances.
