Studio Nisho Nyx

An Organic Oval Designed Around an Offset Flame

Nyx softens rectilinear patios with a flowing 54-by-36-inch silhouette. Its deliberately offset burner leaves a sculpted sweep of concrete beside the flame and gives the feature a distinct view from every angle.

  • Up to 190,000 BTU: Warming Trends Crossfire brass burner
  • 54 × 36 × 16 inches: organic oval form with an offset burner
  • Hand-cast GFRC: architectural concrete with natural finish variation
  • Natural gas configuration: online variants are natural gas; contact us to confirm a liquid propane build

Designed for Gathering

Asymmetry That Makes the Fire Feel Designed

Moving the burner away from the center creates two experiences in one piece: an active flame zone and a broad concrete sweep that visually balances it.

The organic oval works especially well where a square or circle would feel too predictable, and its 16-inch height gives Nyx a slightly taller presence than the rest of the Studio Nisho collection.

  • Made to order: approximately 6–8 weeks before transit
  • Final sale: verify size, finish, fuel, access, and installation requirements before ordering

One Sculptural Footprint

A flowing oval for seating arrangements that need softness, movement, and a fire feature with a clear visual direction.

Planning note: Product dimensions describe the vessel only. Your completed layout also needs safe burner clearances, room for furniture and circulation, a suitable base, gas access, and a clear delivery route.

Built for Outdoor Projects

Curved Concrete, Cast and Finished by Hand

Nyx is hand-cast from glass fiber reinforced concrete in Denver, Colorado. Its continuous curves and asymmetric form make small changes in texture and tone especially visible—and intentionally individual.

The offset Warming Trends Crossfire brass burner is fully adjustable by key valve after a qualified professional completes the fuel connection.

Offset Flame

A deliberate asymmetric composition rather than a centered fire zone.

Brass Burner

Crossfire burner with manufacturer-rated output up to 190,000 BTU.

Complete Package

Burner, plate, valve, flex hose, lava rock, cover, and leveling feet are included.

Concrete Finishes

Four Tones for the Surrounding Architecture

Finish samples and screens can display color differently. Natural variation in hand-finished concrete is expected.

Birch

A warm light neutral for pale stone, limestone, and natural wood palettes.

Smoke

A balanced mid-grey suited to contemporary hardscapes.

Carbon

A deeper charcoal that adds visual weight and contrast around the flame.

Onyx

A near-black option for high-contrast modern installations.

Finish disclosure: Color, movement, texture, and small surface characteristics will vary from online images and physical samples. Small hairline lines may form during curing as moisture leaves the concrete; the manufacturer states these should not affect long-term stability and are not considered manufacturing damage.

Common Questions

Nyx Buying Guide

Is the offset flame intentional?
Yes. The offset burner is Nyx's defining design feature, creating a flame zone on one side and a longer sculpted concrete sweep on the other.
Which direction should the flame face?
Many projects orient the burner toward the primary seating and allow the longer concrete sweep to flow toward a view or open walkway. Confirm the direction before the gas stub and final placement are set.
Can Nyx be ordered for propane?
The variants currently selectable on this page are configured for natural gas. Contact Smokeforges before ordering so a current liquid propane configuration, price, and production estimate can be confirmed.
What clearances should be planned?
The published burner diagram calls for 120 inches of vertical clearance and 36 inches of horizontal clearance from the burner to combustible materials, plus 18 square inches of ventilation on each of two opposing sides. A qualified installer should verify the installation.
What warranty applies?
Studio Nisho currently lists a one-year manufacturer warranty against manufacturing defects on the vessel and a lifetime manufacturer warranty on the brass burner, subject to the manufacturer's current written terms.
