Specifications and design

The Kujira 51" Zen is a large round fire pit designed as a sculptural fire vessel with a minimalist silhouette. Its round fire bowl shape and UHPC construction create a durable outdoor fireplace or modern patio heater appropriate for patios, courtyards, and gardens. Available in Kujira outdoor design color options, the finish is a natural matte that highlights the handcrafted concrete decor and grain of UHPC without extra coating.


Performance and fuel options

The included HPC Match Light burner is configured for easy ignition and accepts Natural Gas or Liquid Propane, letting you choose a fuel type consistent with local codes and site conditions. As a custom gas fire pit-style installation, the basin ships with tumbled lava rock to complete the warm outdoor centerpiece aesthetic while protecting the burner plate. Because the structure is heavy duty at roughly 498 lbs, it is stable on level, solid surfaces.


Placement, installation, and safety

Place the fire bowl on a noncombustible, level base that can support the weight; patios, compacted gravel pads, or reinforced pavers are common. Professional installation is recommended for gas line connections to meet local codes for outdoor fireplace and fire pit systems. Maintain recommended clearances from structures and overhangs and follow all local regulations for outdoor open-flame appliances.


Care, maintenance, and warranty

UHPC is durable, but routine care preserves appearance and function: remove debris from the burner area, inspect fittings before each season, and rinse lava rock if needed. Avoid harsh acids or sealers not specified by Kujira Concrete to protect the natural artisan matte finish. The Kujira 51" Zen includes a 1-Year Limited Warranty from the vendor covering manufacturing defects; warranty details accompany the product.

The Nature of Concrete


KUJIRA products are handcrafted one at a time using a custom concrete formulation designed to endure. Because concrete is a living material, each piece carries its own distinct character—soft tonal shifts, organic texture, and natural variation. This individuality is intentional, embracing the material’s honesty and making every KUJIRA piece truly one of a kind.

Holes & Pock Marks

Naturally occurring air pockets formed during casting.

Color Variation

Subtle shifts in tone are inherent to concrete and vary from piece to piece.

Texture & Flow Lines

Organic movement created as the material settles and cures.

Connection Seam

A visible line where molds meet — intentional, honest, and structural.
