Pairs well with
Studio Nisho Nyx Outdoor Fire Pit
Description
The Nyx by Studio Nisho is a hand-crafted GFRC (glass fiber reinforced concrete) outdoor fire feature that blends sculptural elegance with serious performance. At 54" long and 36" wide, its sweeping curves and offset flame create a dramatic focal point that transforms any patio, terrace, or outdoor lounge into an unforgettable gathering space. Powered by a Warming Trends Crossfire Brass Burner capable of 120K-190K BTU output, the Nyx delivers a flame twice the height of typical prefabricated fire pits while consuming roughly half the natural gas.
Each piece is individually cast and finished by hand, meaning no two Nyx fire pits are exactly alike - the natural character of the concrete ensures your fire feature is truly one of a kind. Available in four refined finishes and compatible with both natural gas and liquid propane, the Nyx is as versatile as it is striking. For discerning homeowners and design-forward outdoor spaces, this is a fire feature that commands attention from the moment it's lit.

FAQ
What is GFRC and why is it used for fire pits?
GFRC stands for Glass Fiber Reinforced Concrete - a composite material that embeds high-strength, alkali-resistant glass fibers into a concrete matrix. It delivers the beautiful, natural appearance of cast concrete while being significantly lighter and more impact-resistant than solid poured concrete. For fire features, GFRC is an excellent choice because it handles thermal cycling well, resists moisture, and allows for detailed hand-crafted shaping that solid concrete cannot achieve as easily.
Does the Nyx fire pit work with both natural gas and propane?
Yes. The Warming Trends Crossfire Brass Burner included with the Nyx is compatible with both natural gas and liquid propane. Simply select your preferred fuel type at the time of purchase. A licensed gas professional should handle all gas line connections regardless of fuel type.
Will my finish look exactly like the photos?
Each Nyx is hand-crafted individually, so minor variations in color and texture are a natural and expected part of the process - no two pieces are identical. The finish photos are representative, but your piece may have slight differences that reflect the character of genuine artisan concrete work. Additionally, small hairline cracks may develop during the concrete curing process; this is normal and does not affect structural integrity or long-term performance.
What does professional installation involve for this fire feature?
Due to the weight of the Nyx (200-400 lbs) and the requirement for a gas line connection, professional installation is strongly recommended. You will need a licensed gas plumber or contractor to run the gas supply line to the fire pit's location and connect it to the 1/2" pipe opening. The burner hardware (key valve and flex hose) is included. Always check local codes and permit requirements before installation.
How does the Crossfire Brass Burner compare to a standard fire pit burner?
The Warming Trends Crossfire Brass Burner uses a patented multi-port orifice design that optimizes the air-to-gas mixture at the point of combustion. This produces a flame that is roughly twice as tall and visually fuller than a standard single-ring burner, while consuming approximately half the gas. The result is a more dramatic, natural-looking flame that makes a striking visual impression - at a notably lower operating cost than comparable BTU output from conventional designs.
Is a cover included with the Nyx?
Yes. Every Nyx ships with a black marine-grade cover featuring the Nisho logo. This weather-resistant cover is designed to protect the fire vessel and burner components from the elements when the fire pit is not in use, helping to extend the life of your investment.
