Care and Maintenance

Clean concrete surfaces with a soft brush and mild detergent; avoid acidic cleaners that can alter the matte finish. Inspect the burner and gas connections annually and clear debris from the lava rock bed before each season. When winterizing, follow your installer’s guidance for propane or natural gas shutoff and protect the unit from standing water.

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.
