Design & construction
The Oni model is built from UHPC (ultra high performance concrete) formulated for strength and a refined surface. Clean geometric edges and a natural matte finish create a minimalist aesthetic that works with contemporary style, luxury home decor, and modern lounge gear. Kujira custom color options allow coordination with terrace tiles, decking, or stonework while preserving the tactile, artisan look of handcrafted concrete.
Burner, fuel, and operation
Equipped with an HPC Match Light burner, the unit supports either Natural Gas or Liquid Propane and ships with tumbled Mexican lava rock for immediate use. The design accommodates a Propane Gas Burner connection and fits standard outdoor fireplace setups; onboard controls and the match light system make ignition straightforward for casual patio gatherings or for use as a 48 inch heater alternative in temperate outdoor rooms.
Placement, weight, and installation considerations
At 353 lbs, the Oni is a substantial large garden feature intended for stable, level surfaces such as reinforced patio slabs or compacted gravel beds. Its 48" footprint reads as a true patio centerpiece and works well with seating arranged around three sides or in lounge-group configurations. Because the unit is handmade, allow for minor surface variation that contributes to its artisan minimalist character.
Care, maintenance & warranty
Concrete surfaces resist routine outdoor exposure but should be cleaned with mild soap and water; avoid harsh acids or abrasive cleaners. Lava rock reduces splash and disperses flame visually; check gas connections annually and follow local codes for propane or natural gas installation. A 1-Year Limited Warranty covers manufacturing defects from Kujira Concrete; refer to warranty documentation for specific terms.
