What is GFRC?

GFRC (Glass Fibre Reinforced Concrete) is a high-performance form of concrete reinforced with alkali-resistant glass fibres. It combines the strength and natural character of concrete with greater flexibility and a lighter finished weight, making it particularly well suited to refined architectural pieces such as concrete basins.

Unlike traditional concrete, GFRC is a composite material made from Portland cement, fine aggregate, water, acrylic polymer, alkali-resistant glass fibre reinforcement, additives and pigments. The glass fibres reinforce the material in much the same way steel reinforcement strengthens conventional concrete, helping create significantly higher flexural and tensile strength.

Why does Consculpt use GFRC for concrete basins?

GFRC allows us to create thinner, lighter and more sculptural forms without losing the strength and substance that make concrete so distinctive. This gives us greater freedom to shape curves, fluting and refined profiles that would be difficult to achieve using traditional concrete.

For a bathroom basin, that combination is particularly valuable. GFRC provides the durability required for everyday use while allowing the finished piece to feel considered and architectural rather than unnecessarily heavy or bulky.

Strong, lightweight and versatile

The high strength-to-weight ratio of GFRC means it can be cast in relatively thin sections while remaining strong and durable. It can also be formed into a wide variety of shapes, colours and textures, giving designers and homeowners greater freedom when selecting a basin for a contemporary bathroom or powder room.

At Consculpt, colour is incorporated into the material to create our considered range of finishes, allowing each basin to work quietly within an interior or become a defining feature of the space.

Handcrafted GFRC basins in New Zealand

Every Consculpt concrete basin is handcrafted in Wānaka, New Zealand. Working with GFRC requires careful control of the mix, casting and finishing process, and each basin is individually made to order before being sealed for use in the bathroom.

The result is a concrete basin that brings together sculptural form, strength and the subtle variation that comes from a genuinely handcrafted material.
