Why a wall suits mosaic tile
Mosaic tile shows its detail best on a wall because a wall is viewed at eye level and at arm's length. The outline of a hexagon, the vein in a 5/8 inch marble square or the sheen on a glass piece stands out there, while the same sheet on a floor is seen from five feet up.
A mosaic wall also takes no foot traffic, so a wall lets glossy glass and polished marble show their shine with no foot traffic to consider. The general guide to mosaic sizes, shapes and sheets is in mosaic tile.
Glass mosaic wall tile
Glass mosaic wall tile reflects light and lets some of it pass through, so a glass backsplash or shower wall changes as the light in the room changes. Under-cabinet lights or a window beside the wall bring out the effect, and glass takes up very little water, which suits splash zones.
Translucent and clear glass mosaics show the setting material behind them, so its color becomes part of the finished wall: white behind pale glass keeps it bright, gray behind it makes it cooler. The range includes glossy squares in Blue, Light Honey and Mare Mist, frosted beach glass, Opalo hexagons and 1x1 glass in Arrecife Blue and Rodas. The full range is in glass mosaic tile.
Interlocking glass slides and liner blends
Interlocking Slides from the Zanzibar Glass collection are long, narrow glass pieces that mix gloss and matte faces and lock into staggered rows. They come in colors such as Marea, Aria, Cenere, Fresco, Nebbia and Crepuscolo, and their pieces are thicker than a typical mosaic, which gives a slide wall a heavier, chunkier look.
Liner Blend glass mosaics such as Candy and Granita set long, narrow glass strips in several tones in horizontal lines. The long lines make a short backsplash look wider, and the mix of tones on one sheet gives the glass a woven, layered look.
Marble mosaic wall tile
Marble mosaic wall tile brings natural veining down to a small scale, so the pieces on a sheet vary from one to the next. Marble mosaic piece scales include 5/8 inch squares, 5/8x3 strips and 2x2 squares, plus hexagons. Polished marble shows the veining crisply and reflects light; honed marble has a soft, matte look.
Marble mosaic examples include Carrara Blend in staggered 5/8 inch squares and hexagons, Alpina White in 5/8x3 strips, Royal Beige and Silver Sky in 2x2, and Emperador Light and Sylvester Beige hexagons. Palladian sheets set irregular marble pieces in a random arrangement, and Calacatta T Multi Finish Palladian mixes polished and honed pieces on one sheet. More choices are in marble mosaic tile.
Herringbone, chevron and Espiga
Herringbone mosaic wall tile comes mostly in marble, in piece sizes from fine Paris herringbone to 1x2 Calacatta T and Siberian White and large herringbone in Bianco Dolomiti and Silver Sky. Thassos and Italian Carrara give a white herringbone, while Bardiglio Light and Sky Blue give a cool gray-blue one.
Chevron mosaic sheets such as Mink White Waterjet and Flecked Canvas Chevron Fusion cut each piece at an angle so the rows meet in a clean point. Espiga, Spanish for an ear of wheat, is the Spanish name for herringbone, and Bardiglio Light is offered under both names in a 1x2 piece.
Hexagons and patterned sheets
Hexagon mosaic sheets come in glass, marble, porcelain and ceramic, from small hexagons up to the larger Blanc and Noir Midi Hexagons. A hexagon wall has no straight lines running across it, so the eye moves over it evenly instead of following a direction.
Patterned mosaic sheets put small pieces into stars, triangles, dots and repeats. Stella, Triad, Polca, Der Vogel and the zig-zag Carrara Blanco porcelain are examples. A bold pattern looks strongest on a defined area such as a niche or the wall behind a vanity, with plain tile around it.
Porcelain and ceramic mosaic options
Porcelain and glazed ceramic mosaics give the small-scale look of a mosaic wall with a water-resistant face: porcelain is dense and absorbs almost nothing, and ceramic relies on its glazed surface. Porcelain and ceramic mosaics are an easy choice for a shower wall or a backsplash behind a range, where splashes are constant, and they come in plain colors as well as stone, marble and wood looks.
Ceramic mosaic choices include Royal White glossy squares, the Blanc herringbone and patterned sheets such as Polca and Grande. Porcelain mosaics add Luna in a 2x2 limestone look, Topo in a 1x1 stone look, Smoke White, Simplicity and Cobblestone Dark in 5/8x3 herringbone, and Peau D Elephant, a wood look porcelain chevron.
Textured, 3D and pebble surfaces
Textured mosaic wall tile has a raised, split or rounded face that casts shadows when light crosses it. Rock Face mosaics in Carrara T and Silver Horizon 1x2 have a split, uneven face; Seagrass 3D Hexagon is a textured limestone hexagon with a raised face; Brera Muretto porcelain recreates a small stone wall; and Rio, Tan and Rustic Birch pebble sheets give a rounded, natural surface.
Textured mosaic walls look their best with light grazing across them from the side, which makes them a strong fit for a fireplace surround, a bar front, an entry wall or a powder room accent wall lit by sconces.
Mosaic for a kitchen backsplash
A mosaic kitchen backsplash is a small, close-up surface, usually the strip between the counter and the upper cabinets, so a modest amount of tile makes a large visual change. Mosaic sheets also divide along their joints, which helps around outlets, switches and the edge of a window.
Glossy glass or polished marble backsplashes bounce task lighting across the counter, while honed marble or matte porcelain gives a quieter, softer surface. More backsplash ideas are in mosaic tile backsplash.
Shower walls and niches
Mosaic on a shower wall usually goes on one feature wall, a vertical band behind the shower head or the inside of a niche, set off by larger tile. A niche is small and seen at close range, which makes it a natural place for a glass or marble mosaic that would be too much over a whole shower.
Using the same mosaic for the shower floor and a band on the wall ties the two surfaces together, and a mosaic niche lined in the floor tile does the same on a smaller scale. The full shower range is in shower tile.
Sheet size, thickness and seams
Many mosaic wall tile sheets at Stone Tile Depot measure close to 12x12, with herringbone sheets around 12 1/8x13 3/8 or 10 7/16x12 13/16. The most common piece thickness is 3/8 inch, while the Interlocking Slides are 11/16 inch, the source of that chunkier look.
Mosaic sheets with interlocking edges, such as hexagons, herringbone and slides, hide the line where one sheet meets the next. Straight-edged square sheets show that line more readily, which is why a staggered square pattern such as Carrara Blend looks more continuous across a wall than a grid of plain squares.
Pairing mosaic with field tile
Mosaic tile is often paired with a larger field tile on the same wall. Common layouts are a mosaic band at eye level, a mosaic panel behind a range or vanity bordered by subway tile, and a mosaic niche inside a large-format shower. Matching colors make the change of scale the feature; contrasting colors make the mosaic the focal point.
Pairing a mosaic with a field tile in the same material also works: a Carrara marble hexagon beside large Carrara wall tile, or a white glass mosaic beside a glossy white subway tile, keeps the room calm while the mosaic adds detail at close range.
Grout color on a mosaic wall
Grout color on a mosaic wall changes the look of the whole surface, because a mosaic has far more joints than a large tile and those joints are a large share of what you see. Grout that matches the pieces makes a mosaic look like one textured surface; a contrasting grout outlines each piece and makes the pattern stronger.
A light grout around pale glass keeps the wall bright, a gray or charcoal grout calms a dark marble, and a white grout on a black hexagon gives a graphic, high-contrast wall. Stain-resistant and epoxy grouts are made for backsplashes and showers, where the joints meet cooking splashes and soap.
