Modterra is a Colorado design studio creating concrete sinks, basins, and objects. The work grew from travel and a life spent in the American West — the colors we returned to, the forms carved by wind and water, the names on old maps most people pass without noticing. We believe objects should carry the memory of how they were made. Each piece is cast slowly, refined by eye, finished by hand, and built to outlast the space it lives in.

About Modterra

Each piece is cast by hand in our Colorado studio. Working directly with the material allows us to control what matters — form, surface, and durability — while accepting the subtle variation inherent to concrete. We move slowly because the material requires it, and every sink is refined and finished by eye before leaving the shop. What you receive is intentional, carefully made, and designed to perform in daily use.

Our Approach

We work in GFRC — glass fiber reinforced concrete. The addition of glass fibers produces a material that is lighter and stronger than traditional cast concrete, with a finer surface that holds form and detail exceptionally well. Like all concrete, it is variable by nature. Color and surface texture will shift slightly from piece to piece, and the material will continue to develop character over time. We consider this part of what makes it worth owning.

The Material

Our colors and forms draw from the landscapes that formed us — canyon walls, volcanic rock, alpine moraine, dry lakebeds, and surfaces shaped slowly by wind, water, and erosion over time. The Strata and Talus collections reference sediment, weathering, and the quiet irregularities found in nature, carrying those influences into the material itself. Nothing is added that does not need to be there.
