Turkish White Marble Window Sill 5x54

This Turkish White marble window sill measures 5 by 54 inches and caps the base of a window opening with a bright, polished edge. It covers the rough sill, gives casing and trim a clean landing, and sheds water away from the wall below. Use it at interior windows or as a slim shelf ledge.

Quarried in Turkey, this white marble shows soft gray veining that shifts from piece to piece, so expect natural variation in tone and movement. Marble is porous, so seal it before use and reseal over time to protect against moisture and staining.

Coordinate it with white marble field tile, thresholds, and liners for a unified look. Measure the opening, allow a small overhang, and set the sill level in thinset. Buy one piece first to check the tone against your tile.
