    Overview

    The BLANCO SUBLINE 430/270-U is an exquisite example of understated elegance, crafted to enhance the modern kitchen with seamless functionality and visual purity. With its dual-bowl design, a generous main bowl alongside a practical secondary bowl, it offers exceptional versatility for busy home cooks, entertainers, and anyone who values efficiency without sacrificing style.

    Designed for undermount installation, the SUBLINE creates a flawless integration with stone or composite benchtops, delivering a smooth, uninterrupted work surface that feels both sophisticated and highly functional. Its precision-engineered geometry maximises usable space within each bowl, making food preparation, rinsing, and cleaning tasks feel naturally intuitive.

    Crafted from BLANCO’s renowned SILGRANIT material, the SUBLINE 430/270-U is exceptionally durable, resistant to scratches, heat, and stains, while offering a soft, stone-like texture that is a pleasure to touch. Its non-porous surface also makes it remarkably hygienic and easy to clean, ensuring it stays as beautiful as the day it was installed.

    More than just a sink, the BLANCO SUBLINE 430/270-U is a celebration of thoughtful design and enduring craftsmanship. It transforms the kitchen into a space where beauty, resilience, and intelligent function come together, elevating the everyday into moments of quiet, confident mastery.
    Timeless Colours, Thoughtfully Designed

    Every Silgranit sink is developed with two guiding principles: it must harmonise beautifully with your kitchen’s colour palette, and it must retain its hue and character for many years. Whether you choose to create a striking contrast or a seamless visual flow, each colour remains timeless, ensuring your sink complements your space with quiet elegance.

    Velvety Texture, Lasting Hygiene

    Silgranit’s wonderfully tactile surface offers a soft, velvety touch paired with a refined matte finish that gently connects to surrounding materials. Beneath this beauty lies advanced protection: the patented Hygiene Plus formula, with antibacterial properties that reduce microbial growth over time. It is a surface that not only feels exquisite but supports a cleaner, healthier kitchen environment.

    Integrated Overflow

    Enjoy a faster draining sink thanks to the integrated overflow.

    Silgranit

    The Silgranit material which is made of 80% granite makes this product seriously long-lasting, protecting against stains, heat, acid, scratches and potential fading.
