Studio Nisho Kratos GFRC Outdoor Fire Feature
Description
The Kratos fire feature from Studio Nisho is a hand-crafted outdoor fire pit that draws its dramatic cauldron silhouette from classical antiquity while delivering thoroughly modern performance. Built from glass fiber reinforced concrete (GFRC) and powered by a Warming Trends Crossfire Brass Burner, it produces a flame twice the size of typical prefabricated fire features. Whether placed on a resort-style pool deck, a private patio, or a commercial outdoor living space, the Kratos commands attention before a single flame is lit.
Each piece is individually cast and finished by hand, meaning no two Kratos fire features are exactly alike - the natural variation in color and texture is part of what makes every installation unique. Available in three sizes and three finish colors, with a choice of natural gas or liquid propane, the Kratos is built to become the centerpiece of a lifetime of outdoor memories.
Key Features
- Hand-Crafted GFRC Construction: Made from glass fiber reinforced concrete with high-strength alkali-resistant glass fibers embedded in the concrete matrix for exceptional durability.
- Warming Trends Crossfire Brass Burner: Produces 120K-190K BTU output - a flame twice the size of typical prefabricated fire features while using roughly half the natural gas.
- Taller, Fuller Flame: The Crossfire burner uses a precise air-to-gas ratio at the point of combustion to create a natural, wood-burning fire appearance.
- Corrosion-Resistant Brass Burner: Sustainable, rust-free brass construction rated at 10K BTU per orifice; compatible with both natural gas and liquid propane via 1/2" pipe opening.
- Available in 36", 42", and 48" Sizes: Three size options to suit patios, pool decks, and large outdoor living spaces of any scale.
- Three Hand-Crafted Finish Colors: Choose from Birch, Smoke, or Carbon - each with its own natural character and slight variation unique to the concrete craft.
- Weight: 200-400 lbs: Substantial weight ensures stability; professional delivery and placement is strongly recommended.
- Black Rolled Lava Rock Fill: Premium 1-3" black rolled lava rock included, enhancing the visual drama of the flame.
- Marine-Grade Cover Included: Black marine-grade cover with Studio Nisho logo protects the fire feature when not in use.
- Complete Valve Assembly Included: Ships with key valve, flex hose, and aluminum burner plate for straightforward installation.
Size & Fuel Options - Which to Choose
- 36 Inch (36" x 36" x 14"): The most intimate size, ideal for smaller patios, courtyards, or as a secondary focal point in a larger outdoor space. Perfect for homeowners who want the full Kratos experience without overwhelming a compact setting.
- 42 Inch (42" x 42" x 14"): The mid-range size strikes the ideal balance between presence and proportion. A great all-around choice for standard residential patios, pool surrounds, and covered outdoor rooms.
- 48 Inch (48" x 48" x 14"): The largest available size, engineered for expansive outdoor spaces, resort settings, and commercial installations where maximum visual impact is the goal.
- Natural Gas: Connects directly to a home's existing natural gas line for unlimited, convenient use with no tank refills. Best for permanent, fixed installations.
- Liquid Propane: Runs from a standard LP tank, making it the right choice where a gas line is not available or for placements that may need to be repositioned seasonally.

FAQ
Does the Kratos require professional installation?
Due to its substantial weight (200-400 lbs depending on size) and the requirement for a gas line connection, professional installation is strongly recommended. A licensed plumber or gas technician should handle the gas line hookup to ensure safety and code compliance. For placement and delivery, white glove freight service is advised.
What is the difference between the natural gas and liquid propane versions?
Both versions use the same Warming Trends Crossfire Brass Burner and deliver the same flame performance. The natural gas version connects directly to your home's existing gas supply line, making it ideal for permanent, fixed installations. The liquid propane version runs from a standard LP tank, which is a great option if you don't have a gas line or want flexibility in placement.
Will my Kratos look exactly like the photos?
Because the Kratos is hand-crafted from GFRC concrete, each piece has its own unique character. Minor variations in color and texture are a natural part of the hand-finishing process, and small hairline cracks may develop as the concrete cures - this is completely normal and does not affect the structural integrity or long-term stability of the product.
Can the Kratos be used indoors or in a covered outdoor space?
The Kratos is designed for outdoor use. If you are considering placing it under a covered patio or pergola, ensure there is adequate overhead clearance and ventilation for gas combustion and flame height. Consult a qualified installer for covered or semi-enclosed applications to confirm it meets local code requirements.
What kind of maintenance does the Kratos require?
The GFRC body requires minimal maintenance - simply keep it covered when not in use with the included marine-grade cover and rinse with water as needed. The brass burner is corrosion-resistant and rust-free. Check gas connections periodically and have the burner inspected by a qualified technician as part of routine seasonal care.
Is the lava rock included, and can it be replaced?
Yes, premium black rolled lava rock (1-3" size) is included with every Kratos. Over time, lava rock can be refreshed or replaced with standard fire pit lava rock available from most hearth and outdoor living retailers.
