Mosaic Tile in Marble, Glass and Porcelain

Start with material, because it decides where a mosaic can go. Marble gives depth and veining and suits bath floors, shower walls and backsplashes, but it is porous and sensitive to acids. Glass holds color, reflects light and includes most of the pool-rated designs. Handmade porcelain is the practical choice for pools and wet zones, with slight variation from piece to piece. Pearl, metal and crackle glass are decorative wall materials best seen at close range.

Finish comes next. Polished marble is bright and makes color look deeper, which suits walls and backsplashes. Honed marble is matte, less slippery when wet and better at hiding fine wear, so it is the usual choice for floors. Many Elysium collections offer the same stone both ways, which lets a bathroom floor and wall share one marble.

For a shower floor, smaller pieces help: 1 in penny rounds, 2 in hexagons and pebbles follow the slope to the drain, and their many joints add grip. Check each product page, since Elysium states shower-floor suitability design by design. For pools and spas, use only pool-rated designs and the setting system Elysium recommends, a glass-tile mortar with latex additive and a pool-grade grout. Some stained glass, such as the Newport series, has sharp edges and must never go where bare feet step.

Grout is a design decision as well as a technical one. On small mosaics it covers a large share of the surface, so a pale grout softens a pattern and a contrasting one outlines it. Elysium lists a suggested grout for most designs, and glass and pearl need a white thin-set so the adhesive does not show through.

Mosaic sheets are rarely exactly one square foot. Most Elysium sheets measure between about 9.5 and 13.5 in per side, so calculate coverage from the actual sheet size and add roughly 10 percent for cuts, more for intricate patterns. Keep a few spare sheets from the same lot for future repairs. Most sheets are mesh-backed; some glass arrives paper- or face-mounted, with a front layer the installer removes before grouting.

Natural stone needs sealing. Elysium recommends a stone sealer for its marble mosaics, and some glass-and-stone blends must be sealed before going into a shower. Seal after grouting, clean with a pH-neutral cleaner and reseal on the schedule your sealer specifies. Our team in Glendale can help you compare samples and plan quantities.
