About Me
Hi, I’m Sebastian Erb, the founder and maker behind Modern Mix SD. Born from a lifelong passion for design, craftsmanship, and materials, Modern Mix is my way of blending artistry with function. I create handcrafted glass fiber reinforced concrete (GFRC) pieces, high-end wooden pivot entry doors, and custom furniture that bring a natural yet modern aesthetic into every space.
With a background in high-end millwork and product design, and roots that trace back to German precision and craftsmanship, I built Modern Mix right here in San Diego, California, where every piece is made locally and to order. I believe great design should feel timeless — minimalist lines, honest materials, and textures that tell a story.
Each sink, vanity, or table starts as a raw idea in my workshop and is shaped by hand using the finest GFRC concrete and responsibly sourced wood. The result: durable, sculptural pieces that reflect a balance of warmth, structure, and individuality.
Modern Mix is more than a brand — it’s a creative pursuit to make everyday objects feel special. Every product that leaves the studio represents a blend of my German roots, California lifestyle, and a commitment to slow-made quality.
