The Cronus is a classically inspired, masterfully crafted outdoor fire pit that commands attention in any setting. Hand-built from glass fiber reinforced concrete (GFRC), it delivers the kind of substantial, architectural presence that elevates a patio, terrace, or poolside lounge into something truly special. At 48" square and weighing up to 400 lbs, this is a permanent statement piece designed for serious outdoor living.
At its core is the Warming Trends Crossfire Brass Burner, producing a taller, brighter, fuller flame that mimics a natural wood-burning fire - at up to 190,000 BTU. Whether you're hosting large gatherings or settling in for a quiet evening, the Cronus delivers warmth and ambiance that effortlessly holds the room. Available in four handcrafted concrete finishes, each piece is uniquely its own.
Key Features
GFRC Construction: Hand-crafted from glass fiber reinforced concrete with high-strength alkali-resistant glass fibers embedded in the concrete matrix - built to last outdoors.
Warming Trends Crossfire Brass Burner: Produces flames twice the height of typical prefabricated burners using roughly half the natural gas, thanks to a precise air-to-gas ratio at point of combustion.
120K-190K BTU Output: 10,000 BTUs per orifice deliver serious heat output for large outdoor spaces and chilly evenings.
Natural Gas or Propane Compatible: Works with both natural gas and liquid propane via a 1/2" pipe opening - choose the fuel type that fits your setup.
48" x 48" x 14" Footprint: Generous square form with a low profile designed to anchor seating areas and outdoor entertaining spaces.
Weight: 200-400 lbs: Substantial concrete construction ensures stability and a truly permanent, built-in aesthetic.
Four Handcrafted Finishes: Choose from Birch, Smoke, Carbon, or Onyx - each finish is unique, with natural variation in color and texture that makes every piece one of a kind.
Premium Lava Rock Fill: Includes black rolled lava rock (1-3" size) for a refined, polished fire feature look.
Marine Grade Cover Included: Black marine-grade cover with Nisho logo protects the fire pit when not in use.
Complete Hardware Package: Comes with key valve, flex hose, and aluminum burner plate - everything needed for a clean installation.
Fuel Options & Which to Choose
Natural Gas: Best for permanently installed fire pits connected to a home or commercial gas line. Offers unlimited, continuous fuel without the need to swap tanks - ideal for frequent entertainers and permanent outdoor spaces.
Propane: Best for locations without access to a natural gas line. Uses a standard liquid propane tank, giving you placement flexibility without running gas lines. A great choice for decks, patios, or new construction where gas infrastructure isn't yet in place.

FAQ
Does the Cronus require professional installation?
The fire vessel itself does not require assembly, but connecting the burner to a natural gas or propane supply should be done by a licensed gas technician. All hardware (key valve, flex hose, aluminum burner plate) is included. Always follow local codes and regulations for gas appliance installation.
What is GFRC and why is it used for fire pits?
GFRC stands for Glass Fiber Reinforced Concrete. It combines high-strength alkali-resistant glass fibers with a concrete matrix, resulting in a material that is significantly stronger and more crack-resistant than standard concrete while also being lighter relative to its volume. It handles outdoor temperature fluctuations well and is an ideal choice for a high-end fire feature that needs to look great for years.
Are the small variations in finish color and texture a defect?
No - variation is a natural and expected characteristic of handcrafted GFRC concrete. Each Cronus is finished by hand, meaning slight differences in color and texture from piece to piece are part of what makes it unique. Small hairline cracks may also develop as the concrete cures and moisture escapes - this is a normal part of the process and does not affect structural integrity or long-term durability.
How does the Crossfire Brass Burner compare to a standard fire pit burner?
The Warming Trends Crossfire Brass Burner uses a patented design that controls the air-to-gas ratio at the point of combustion, producing a flame that is roughly twice the height and brightness of a typical prefabricated burner - while using about half the gas. It's made from corrosion-resistant, rust-free brass and is built to last in outdoor environments. The result is a fire that genuinely resembles a natural wood-burning flame.
How is the Cronus shipped, and how heavy is it?
The Cronus ships via freight due to its substantial weight of 200-400 lbs. Delivery is typically curbside, and you will need adequate help or equipment to move it into position. Contact us at service@omahasportsandgames.com before purchasing if you'd like a shipping quote or to discuss delivery options for your location.
Can I use the Cronus with a natural gas line if I currently have propane, or vice versa?
The Crossfire Brass Burner is compatible with both natural gas and liquid propane, but you must select your fuel type at the time of purchase as the burner orifices are configured differently for each. Converting between fuel types after purchase is not a simple swap and would require a technician. Choose the option that matches your existing or planned gas supply.
