      The right trim is what takes an installation from finished to refined. Pure white Thassos marble moldings, liners, and decorative borders — in the same brilliant white as the field tile — to frame edges, cap walls, and add crisp, elegant detail to any Thassos project.

      Why add trims & moldings
      Moldings and trims do the finishing work that elevates a design: they cap exposed tile edges for a clean, professional look, frame niches and accent bands, and separate fields of tile with a crisp line. Cut from the same brilliant white Thassos marble as the field tile, these trims match perfectly — and decorative options like BIAS and basketweave borders with colored dots add a custom, classic touch that off-the-shelf trim can't replicate.
      Pencil Liner
      Slim 1/2×12 and 3/4×12 strips to frame backsplashes and border niches.
      Baseboard
      Floor-to-wall transition profiles for fully coordinated marble rooms.
      Chair Rail
      One-step chair rail profiles for wainscot and mid-wall detail.
      Quarter Round
      Rounded profiles that finish outside corners and exposed tile edges.
      BIAS Dot Borders
      2×12 borders with black, blue-gray, or Ming Green dots for a decorative band.
      Basketweave Border
      Honed basketweave borders with colored dot accents for a classic look.
      Ordering & care: Trims are sold by the piece — calculate your linear footage and add a little extra for cuts. Match the finish to your field tile and order at the same time so lots match. Thassos is natural marble, so seal it, clean only with pH-neutral products, and set with white thinset to keep the bright stone from discoloring. Order a sample to confirm the tone.
