Custom Window Sill Gallery
Thirteen made-to-measure window sills in hardwood, solid surface and painted finishes — kitchens, baths, bedrooms and living rooms. Every piece is cut to exact dimensions with a machined edge profile and a laminated build-up front. Browse by material, then configure your own or see the full materials and colors.
Every image below is a rendering, shown to illustrate materials and proportions available through the configurator.
Hardwood Window Sills
Solid walnut, white oak, maple and cherry, stained and sealed. Grain runs the length of the sill, and the front is built up from laminated stock so the piece reads as one thick slab.
White Oak Sill in a Modern Kitchen
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.
Walnut Sill in a Bedroom
Walnut stained dark enough to hold its own against a black window frame, run wall to wall as a single length. The square front edge and flat return keep the profile quiet so the view does the work.
Walnut Window Stool, Traditional Room
A traditional window stool in walnut, sized to sit proud of the apron below and returned into the jamb at each end. This is the classic replacement profile for double-hung windows in older homes.
Walnut Sill in a Reading Nook
A narrow-depth walnut sill at seat height, finished to a low sheen that picks up the grain. Deep enough to hold books and a bowl without crowding the casement hardware.
Wide Walnut Sill, Living Room
A long walnut run spanning a multi-panel window wall. At this length the sill becomes a shelf — wide enough for planters and stacked books, with the front edge left square to match the trim.
Solid Surface Window Sills
Non-porous solid surface in 77 colors, seamless and repairable. Because it is homogeneous through the thickness, the build-up edge can be machined to any profile with no visible seam.
White Solid Surface Sill
A bright white solid surface sill with a crisp machined edge and no visible seam where the build-up meets the deck. Non-porous, so it shrugs off condensation on the glass above it.
Cream Solid Surface Sill in a Bath
A warm cream solid surface sill run past a freestanding tub. In a wet room this is the practical choice — the material is non-porous, and a scuff can be sanded out rather than refinished.
Limestone-White Sill at the Tub
Limestone-white solid surface with a squared return at the open end, so the sill terminates cleanly rather than dying into the wall. The matte surface reads like honed stone without the sealing.
Soft White Sill, Kitchen Casement
A soft white sill beneath a bank of casements, set deep enough to line up with the cabinet run and hold cookbooks. The flat front and tight radius keep it reading as architecture, not trim.
Painted Window Sills
Any of 373 Sherwin-Williams colors, sprayed in 2K polyurethane over a paint-grade substrate and available in matte, satin or semi-gloss — the way to match existing trim exactly.
Navy Painted Sill in a Bath
Deep navy sprayed to a matte film, carried the full width of the window and squared at the front. Matte hides prep and touch-ups better than any other sheen, which suits a long uninterrupted run like this one.
Navy Painted Sill, Oceanfront Room
The same navy taken across a full window wall at seat depth. At this scale the sill becomes a datum line through the room, so the colour was chosen to sit down against the glazing rather than compete with the view.
Sage Painted Sill in a Bath
A muted sage run against warm plaster, painted rather than stained so the colour could be pulled from the tile instead of the timber. Satin sheen — enough to wipe clean in a bathroom, still forgiving on the profile transitions.
Deep Green Painted Sill
A deep green sill with a squared return at the open end, set into a library nook. Painting rather than staining let the sill match the room's joinery exactly instead of approximately.
