Description
The Radius from Timberline is a 400mm round semi-inset basin in glossy white ceramic. The bowl drops half-recessed into the vanity benchtop so the lower portion sits below the bench surface and the upper rim rises above — giving you the architectural interest of an above-counter vessel without the full above-counter height.

About round semi-inset basins
Semi-inset basins (also called half-recessed basins) sit half-in and half-out of the vanity benchtop — the bowl drops into a cut-out so the lower portion sits below the bench surface, while the top of the rim rises above. The effect is a softer, more architectural look than a fully inset basin, but with less bench-clearing depth than a tall above-counter vessel.
Round semi-inset basins are the most versatile shape in this category. The circular footprint softens the strong horizontal lines of vanities and mirrors, and the half-in mounting keeps tapware reach manageable while still letting the basin act as a visual feature on the vanity. Gloss white ceramic remains the most versatile finish — the high-gloss glaze reflects bathroom light, wipes clean with a soft cloth and mild soapy water, and shows water marks less than matte ceramics.
Pair a Timberline semi-inset basin with a wall-mounted basin mixer behind the basin, or with an offset deck-mounted basin mixer drilled into the benchtop to one side. Add a matching 32mm pop-up waste to coordinate with your tap finish.
