Nyx is named for the Greek goddess of night, and the piece lives up to it. While most fire pits are designed to look good in daylight product photos, Studio Nisho designed Nyx for the hours that matter — when the sun drops, the flame rises, and her curved silhouette becomes the glowing center of the evening.
The form is unlike anything else in the Nisho collection: a flowing 54-by-36-inch organic oval, hand-cast in glass fiber reinforced concrete, with the flame deliberately set off-center. That single asymmetric decision gives Nyx her signature look — a sculptural sweep of concrete on one side, a Warming Trends Crossfire brass flame on the other, and an elegance that turns any recreational space into the setting for an unforgettable night.
The burner sits intentionally off-center, breaking the symmetry every other fire pit follows — and leaving a graceful sweep of concrete surface flowing away from the fire.
Soft, continuous curves across a 54-by-36-inch footprint give Nyx a sculptural, almost hand-thrown quality that squares and circles can't imitate.
Warming Trends' brass jets deliver 120K–190K BTU of tall, bright, wood-fire-like flame while drawing noticeably less fuel than conventional ring burners.
Cast by hand in Denver from glass fiber reinforced concrete — alkali-resistant glass fibers throughout the matrix for stone-like presence at 200–400 pounds.
A 1/2-inch pipe connection accepts either fuel, keeping the installation flexible whether you're plumbing a line or running propane.
Key valve, flex hose, aluminum burner plate, rolled lava rock, and a fitted marine-grade cover all ship in the crate — nothing extra to hunt down.
Great fire features earn their place twice a day. Here's how Nyx works for you around the clock — and why the offset flame is the smartest design decision on this page.
Flame off, Nyx reads as pure landscape art — a smooth, curved concrete form that softens the straight lines of decking and pavers. The asymmetric silhouette shifts as you move around it, and the long sweep of surface beside the burner zone doubles as a natural ledge for drinks and small plates while you entertain.
Flame on, the offset placement earns its keep: firelight rakes across the curved concrete at an angle, throwing soft shadows along the vessel's sweep instead of lighting it flat. It's the difference between a lamp and a scene — and it's why Nyx photographs best, and hosts best, after dark.
An asymmetric, continuously curved vessel is one of the hardest forms to cast in concrete — there are no straight edges to hide behind, and every inch of the surface is on display. Studio Nisho casts each Nyx by hand in its Denver workshop using glass fiber reinforced concrete: high-strength, alkali-resistant glass fibers embedded through the full concrete matrix, giving the thin-walled curves the resilience plain concrete can't offer.
Each of the four finishes — Birch, Smoke, Carbon, Onyx — is applied by hand, which means subtle variation in tone and texture from piece to piece. Fine hairline lines may also appear over time as the concrete cures and releases moisture; both are natural characteristics of architectural concrete, don't affect structural soundness, and are the fingerprint that makes your Nyx yours alone.
Below the fire surface, the Crossfire burner carries the same standard: brass jets machined to resist rust and corrosion through years outdoors, feeding a flame engineered to look like a natural wood fire without the smoke, sparks, or cleanup.
One size, one silhouette, four moods. Given how Nyx lives for the evening, consider how each finish behaves in firelight, not just afternoon sun.
Pale and luminous — catches firelight like candlelit limestone, the brightest nighttime glow of the four.
Soft grey that shifts warm under flame and cool in daylight — the shape-shifter of the palette.
Deep charcoal that lets the curves fall into shadow while the flame takes the spotlight.
Near-black — the truest expression of the Nyx name, where the vessel disappears into night and only fire remains.
Finish note: every concrete finish is hand-applied and unique to its vessel. Expect subtle variation from sample photos — the individuality is part of the piece.
The burner's 1/2-inch pipe connection runs on either fuel. Natural gas offers uninterrupted evenings where a line exists or can be trenched; propane keeps things flexible everywhere else. A licensed gas professional should complete the final hookup and size the supply for full burner output.

Made-to-order craftsmanship: each Nyx is hand-cast and hand-finished after your order is placed, which is why these pieces are final sale. Call or email before ordering and we'll confirm current production timelines for your finish.
Because the flame is offset, Nyx has a direction — decide which way the fire faces before delivery day. Many owners aim the burner end toward the primary seating and let the long concrete sweep flow toward the view or walkway. Walk the space at dusk and picture it lit; the right orientation becomes obvious.
Set the vessel on a level, non-combustible surface such as concrete, stone, or pavers. Warming Trends specifies 120 inches of vertical clearance and 36 inches of lateral clearance from combustible structures or materials, plus 18 square inches of venting on opposing sides — your installer should verify these against local code using the diagram linked below. Covered outdoor rooms need particular attention to that vertical clearance.
Rough in the gas stub before the vessel arrives, positioned per the Warming Trends diagram — and remember the offset burner location when planning the stub, since the connection point won't be at the vessel's center. A licensed gas professional makes the final connection and sizes the line for full output.
Nyx ships free via LTL freight with curbside delivery — free shipping on all orders, always. At 200–400 pounds, plan for two or more people or a heavy-duty dolly to move her from the curb to the patio.
Completely — it's the defining design decision of the piece. Setting the burner off-center creates the asymmetric composition Nyx is known for: fire on one end, a flowing sweep of sculpted concrete on the other. The Crossfire burner performs identically to a centered installation; only the artistry changes.
Yes — with up to 190,000 BTU on tap, the Crossfire burner produces generous radiant warmth well beyond the vessel's edge. Seating naturally gravitates toward the flame end, and the key valve lets you raise output on cold nights so the whole circle stays comfortable.
Only if the structure satisfies the burner's clearance requirements — Warming Trends specifies 120 inches of vertical clearance from combustible materials, along with 36 inches laterally. Some tall, open outdoor rooms can meet that; many pergolas can't. Have your installer verify against the clearance diagram linked below and local code before committing to a covered location.
Nyx is the collection's romantic — the only piece with an organic oval form and an offset flame. Kratos offers the classic round cauldron, while Chaos and Cronus explore square geometry in modern and classical directions. If your space calls for softness, movement, and evening drama, Nyx is the one. Happy to compare them for your layout at 833-777-2962.
Point the burner end toward where people actually sit — the flame becomes the focal point of the seating zone while the concrete sweep trails toward the open side, the view, or the garden. If the piece will be seen from indoors, orienting the flame toward your main windows makes Nyx a nightly show from inside the house too.
Low-maintenance by design: an occasional gentle wash with a few drops of mild detergent in warm water and a microfiber towel, followed by an optional spray beeswax polish for extra luster. Keep the included marine-grade cover on between uses to protect both the finish and the burner hardware, and let damp lava rock dry for about 30 minutes on first light after wet weather.
