Master Bath Calacatta Marble Floor in West Dundee
About This Project
This master bathroom in a West Dundee home received new large-format Calacatta marble-look porcelain tile throughout the floor. The homeowner wanted the look of real marble without the maintenance demands of a porous natural stone in a wet environment. Large-format porcelain in a marble look achieves that, and with fewer grout lines across a wide floor it reads more like a continuous slab.
The existing subfloor was a concrete slab, which we verified was flat to within the required tolerance before setting any tile. We used a large-notch trowel and back-buttered every tile to achieve full mortar coverage, which is required under tiles larger than 15 inches per side. The glass shower enclosure and dual walnut vanities were already in place, so all cuts at the perimeter and around the vanity bases were finish cuts visible to the eye.
What We Did
Assessed slab flatness and moisture; confirmed no leveling compound needed
Dry-laid full tile field to establish layout and optimize perimeter cuts
Set tile in white non-staining thinset to prevent mortar bleed-through on light material
Grouted with light gray sanded grout; sealed perimeter in silicone to match
