Dark Marble-Look Living Room Floor in Westmont
About This Project
This Westmont home's large living and dining area received a complete floor replacement with 32x32-inch polished dark gray marble-look porcelain. The high-gloss polished finish amplifies the light in the open-plan room while the dark marble veining gives the floor a dramatic, anchoring presence. Working with a polished tile of this format requires extra attention to lippage — any height variation between tiles is visible and catches the light sharply. We used a full leveling clip system throughout and verified flatness with a straightedge on every 10-foot section before grout was applied.
The slab in this Westmont property was in good condition, requiring only spot-leveling in a small area near the kitchen transition. Because the tile is polished, we used white modified thin-set (darker thin-set can show through a polished glaze body on light grout joint areas if it bleeds). Grout joints were kept at 1/16 inch with a matching dark gray unsanded grout.
What We Did
Removed existing flooring, spot-leveled slab near kitchen boundary
Laid out tile from room center, accounting for fireplace and sliding door as visual anchors
Set 32x32 polished porcelain with white modified thin-set, back-buttered, full leveling clip system
Grouted with dark gray unsanded grout at 1/16-inch joints, installed flexible sealant at perimeter
