Cobalt blue subway tile can add a vivid accent to a kitchen backsplash, bathroom wall, or other interior surface. For a traditional ceramic installation, the Tenedos 3-by-6-inch tile is a direct fit; for cobalt blue glass, compare the Adedeo loose tiles and Lovdeco peel-and-stick option. MOONFUN offers a thicker self-adhesive format, but its listed details do not specify the color, so confirm the shade before choosing it.
| Product | Best For | Material or Format |
|---|---|---|
| Tenedos USCT 3×6 | Glossy ceramic walls | Ceramic tile |
| Adedeo 3×6 | Loose cobalt glass tiles | Glass tile |
| Lovdeco 3×6 | DIY cobalt glass projects | Peel-and-stick glass |
| MOONFUN 10 Sheets | Self-adhesive backsplash projects | Thick vinyl; color not specified |
| Art3d 102-Pack | White subway-tile alternative | Peel-and-stick PVC |
Tenedos USCT 3×6 Ceramic Subway Tile

This is the best choice for shoppers seeking a conventional cobalt blue ceramic subway tile. Each box contains 10 pieces, and the 3-by-6-inch format suits classic horizontal layouts as well as other wall patterns. Its high-gloss finish reflects light, making it a consideration for backsplashes and accent areas where a shiny surface is desired.
The listed uses include kitchen backsplashes, bathroom and shower walls, laundry rooms, fireplace surrounds, and accent walls. Choose this product if you want ceramic rather than a peel-and-stick surface. The box contains only 10 pieces, so calculate the required quantity from the project area and allow for cuts and breakage. The listing does not provide coverage per box.
Adedeo Cobalt Blue Glass Subway Tile

Adedeo is best for buyers who want cobalt blue glass in individual 3-by-6-inch tiles. The product is sold as loose tiles rather than mounted sheets, which allows flexibility when planning a layout. Its listed 8 mm thickness is described as giving the tile a three-dimensional appearance and added durability.
The package information states 32 pieces and 4 square feet per box. This makes it easier to estimate coverage than products without a stated area. Choose it if you want glass and prefer to arrange separate tiles. Because these are loose tiles, installation involves handling and positioning individual pieces; shoppers seeking a quick peel-and-stick application should compare the Lovdeco option instead.
Lovdeco Peel-and-Stick Cobalt Glass Tile

Lovdeco is best for DIY buyers who want cobalt blue glass with a peel-and-stick installation format. The listing specifies 40 pieces measuring 3 by 6 inches, with total coverage of 5 square feet. It says the tiles do not require grout or glue and can be arranged in different patterns, including subway and herringbone layouts.
Choose this option if the stated coverage and adhesive format fit your project. The listed coverage is limited to 5 square feet per box, so a larger wall will require careful quantity planning. The product description does not explain surface preparation or installation limits; check those details before applying it to a particular wall or backsplash.
MOONFUN Thicker Peel-and-Stick Subway Tile

MOONFUN is best for buyers comparing a thicker self-adhesive backsplash format. The package includes 10 sheets measuring 12 by 12 inches each and covers around 10 square feet. Each vinyl tile is listed as 2.5 mm thick, with an adhesive backing and stated resistance to moisture, oil, heat, and water.
The key limitation for a cobalt blue tile search is that the supplied product details do not identify its color. Confirm the available shade and pattern before buying; the listed features alone do not establish that it is cobalt blue. Choose it only if its color matches your project and you want sheet-format vinyl rather than individual ceramic or glass tiles.
Art3d White Peel-and-Stick Subway Tile

Art3d is a useful comparison for shoppers who are open to white subway tile rather than cobalt blue. The 102-pack contains individual 3-by-6-inch PVC tiles that can be arranged in different layouts. The listing describes them as waterproof, heat resistant, stain resistant, scratch resistant, and easy to clean. It also says the pieces can be cut with tin snips, a utility knife, or a hand saw.
This is not a cobalt blue option: its listed color is glossy white. Choose it only if a light neutral backsplash is acceptable or if you are comparing peel-and-stick PVC construction with the cobalt ceramic and glass choices above. It is not the right pick when matching a cobalt blue color is essential.
Buying Guide: How to Choose Cobalt Blue Subway Tile
Should you choose ceramic, glass, or peel-and-stick?
Choose ceramic if you want a conventional hard tile and a glossy cobalt finish. Choose loose glass tile if color and individual-tile layout flexibility are priorities. A peel-and-stick product may suit a DIY project, but check its material, color, installation instructions, and intended surface before purchase. Peel-and-stick vinyl is not the same material as glass or ceramic.
How much tile should you buy?
Measure the wall’s width and height, then calculate the area. Compare that figure with each listing’s stated coverage: Adedeo lists 4 square feet per box, Lovdeco lists 5 square feet per box, and MOONFUN lists around 10 square feet per package. Tenedos does not state coverage per box in the supplied features. Plan for cuts and check the seller’s current package details.
Which format suits the installation?
Loose tiles offer individual placement but require positioning each piece. Peel-and-stick formats advertise a simpler adhesive-based process, though preparation and surface suitability still matter. For a shiny look, the Tenedos ceramic tile specifically lists a high-gloss finish. Review product instructions before using any tile in a wet area.
