Blue glass subway tile can add color and a reflective finish to a kitchen, bathroom, or shower wall. For a classic 3-by-6-inch layout, consider Lovdeco’s blue tile or Diflart’s light blue tile; choose the cobalt option for a deeper color. Lovdeco’s 4-by-12-inch tile offers a longer shape, while Diflart’s peel-and-stick product is designed for a simpler, grout-free makeover. Compare each product’s dimensions, coverage, and installation format before ordering.

Lovdeco Blue 3-by-6-Inch Glass Tile

This option uses the familiar 3-by-6-inch subway tile shape and provides 4 square feet per box. Lovdeco lists 32 pieces per box and an 8 mm thickness. The brand describes the tiles as glass and positions them for kitchens, bathrooms, pools, and other spaces.
Best for: Buyers seeking a conventional blue subway-tile format for a backsplash or wall project. The standard dimensions make it a straightforward choice to compare with other 3-by-6-inch options. Choose it if you want a blue finish without moving to an extra-long tile shape.
Consider: The listing provides coverage by box, so calculate the project area and allow for cuts and breakage when determining how many boxes to order. Confirm the shade and installation requirements with the product listing before purchase.
Diflart Light Blue 3-by-6-Inch Tile

Diflart’s light blue glass tile comes in a 3-by-6-inch size, with 32 pieces covering about 4 square feet per box. The listing notes a glossy surface, straight edges, and a thickness of approximately 0.31 inch. It also describes the tile as waterproof, stain-resistant, and easy to clean and maintain.
Best for: Buyers who want a lighter blue tone and a traditional subway shape. The stated wet-area suitability makes it a candidate for bathroom walls and shower applications, subject to appropriate installation and surface preparation.
Consider: This product is sold as individual pieces, according to its listing. Confirm the package quantity and ordering details before checkout, especially when calculating coverage for a larger project.
Lovdeco Ice Blue 4-by-12-Inch Tile

This Lovdeco option changes the proportions of a classic subway tile with a 4-by-12-inch format. Each box contains 12 sheets and covers 4 square feet; the listed tile thickness is 8 mm. The product is described as glass and intended for areas such as kitchens, bathrooms, and pools.
Best for: Buyers who prefer longer, larger-format subway tiles over a 3-by-6-inch pattern. Its dimensions can create a different visual rhythm on a backsplash or wall while retaining a rectangular shape.
Consider: The larger tile format may not suit every layout or small area with many corners and cutouts. Plan the pattern and confirm the ice-blue shade against nearby finishes before ordering.
Diflart Peel-and-Stick Light Blue Tile

Diflart’s self-adhesive tile is listed at 3 by 11.8 inches and approximately 0.2 inch thick. A box contains 20 pieces and covers about 4.84 square feet. The product description says it uses genuine glass, has a glossy surface, and does not require grout; it is applied by peeling off the backing and placing it on a clean, flat surface.
Best for: Buyers seeking a faster makeover with an adhesive-backed format rather than a conventional grout installation. It offers a longer subway shape and more stated coverage per box than the 4-square-foot options above.
Consider: The listing calls for a clean, flat surface. Avoid choosing it if the intended wall is uneven or if your project specifically requires a traditional grouted tile installation.
Adedeo Cobalt Blue 3-by-6-Inch Tile

Adedeo’s cobalt blue tile is listed in a 3-by-6-inch size, with 32 loose tiles per box covering 4 square feet. The listed thickness is 0.31 inch, or about 8 mm. The seller describes the loose-tile format as flexible for installation and suitable for DIY projects.
Best for: Buyers who want a more vivid cobalt color in a standard subway-tile size. It is a useful comparison against lighter blue products when selecting the overall color impact of a kitchen or bathroom wall.
Consider: The product is supplied as loose tiles rather than a sheet format. Account for individual placement during installation and verify that the bold color works with the room’s lighting and surrounding materials.
Buying Guide: How To Choose Blue Glass Subway Tile
Which tile size fits the design?
Compare dimensions before choosing by color alone. A 3-by-6-inch tile is a familiar, compact rectangle. The 4-by-12-inch Lovdeco option and 3-by-11.8-inch peel-and-stick tile create a longer proportion. Consider the wall’s dimensions, corners, outlets, and intended layout when estimating cuts.
How much coverage should you order?
Four of the listed products provide about 4 square feet per box; the Diflart peel-and-stick option lists about 4.84 square feet. Measure the area in square feet, then check the product’s current package coverage and quantity. Add an allowance for cuts and breakage based on the project layout, and confirm how the seller packages the tile.
Should you choose adhesive-backed or conventional tile?
The peel-and-stick option is described as self-adhesive and grout-free, with clean, flat surfaces specified for application. The other options are conventional glass tiles, but the provided product details do not specify all installation materials or methods. Review the manufacturer’s instructions and consult a qualified installer when needed, particularly for wet-area projects.
What color and finish work best?
Light blue can suit a softer palette, while cobalt offers a stronger color statement. Glossy glass surfaces reflect light, so compare samples or listing images with the room’s lighting and cabinets, counters, grout, or fixtures. Online images may not reproduce color exactly.
