Full Description

Introducing the Cubrosa – a minimalist cube planter engineered for bold outdoor statements. This 55cm square vessel balances contemporary style with strength and scale, offering a geometric alternative to traditional round pots. Its clean lines and solid build make it ideal for structured planting — from low clipped shrubs to striking evergreen forms.

Handcrafted from premium pigmented concrete and reinforced with internal steel, the Cubrosa planter is built for real-world durability. The raw finish showcases gentle pitting and tactile surface character, while the embedded Onyx Dusk pigment — a deep fusion of charcoal, black and grey — ensures the colour stays consistent and won’t peel or fade.

Designed for both private and commercial settings, the Cubrosa’s 33.5kg weight gives it natural resistance to movement and theft. It’s frost-resistant, UV-stable, and internally sealed to extend life and prevent moisture ingress — making it a year-round feature in all weather conditions.

Whether used solo, in pairs, or as part of a grid layout, the Cubrosa delivers sculptural simplicity with serious planting performance.
