At Robertson Bathware, we offer a comprehensive range of internal valves and concealed wall parts designed to work seamlessly with tapware and mixers. These essential components are not only practical but are also an important part of achieving a sleek, modern bathroom design. Concealed wall parts, in particular, allow for a clean, minimalist look by hiding the plumbing inside the wall, leaving only the tap or mixer visible.
Our internal valves are built for precision and durability, ensuring reliable performance for years to come. They regulate water flow, providing smooth and consistent control over your tapware and mixers. With our wide selection of high-quality valves, you can ensure your bathroom fittings work efficiently and effectively.
Whether you’re renovating an existing bathroom or installing new fixtures, concealed wall parts and internal valves offer both functional benefits and a stylish finish. These parts come in a variety of designs, allowing you to find the perfect match for your bathroom aesthetic, from classic to contemporary.
