A deep white oak sill carried across a three-panel window run and squared off at the front with a heavy build-up edge, so the piece reads as one solid slab rather than a trim board. The natural stain sits close in tone to the rift-sawn cabinetry below.

Hardwood sills are cut from solid stock, so the grain runs the full length of the piece and the front edge is built up from laminated lengths rather than veneered — the sill reads as one thick slab from every angle. Walnut, white oak, maple and cherry are stocked, each offered across the Spectrum Finishing stain library. Timber moves with humidity, so a hardwood sill is sized against the opening with a deliberate reveal and the end grain is sealed before it ships.
A kitchen sill takes more punishment than most — splashes at the sink, heat and steam, things set down on it without thinking. Depth usually gets set by the counter run below it. Whatever the room, the sill is cut to your opening rather than trimmed to fit on site — length, depth, horn projection and corner treatment are all set before it is machined.
Measure jamb to jamb, then the depth from the window frame to where you want the front edge to land, and the horn length past each side if the sill returns into the wall. The configurator draws the piece live as you enter dimensions and produces a dimensioned spec sheet you can hand to an installer. See the measuring guide for the full method, or compare wood against solid surface before choosing.
