For a 12×24 marble tile shower, the two Italian Carrara products below are the closest matches: both are polished natural-stone field tiles in the requested size. They are best considered for shower walls, not as a default shower-floor choice. The other listed products are peel-and-stick vinyl or backsplash sheets; they do not match a conventional marble shower installation, so review their intended use carefully before buying.
| Product | Type and size | Best suited for |
|---|---|---|
| Bianco Carrara White Italian Marble | Polished natural marble, 12×24 | Buyers seeking white stone with gray veining |
| Italian Carrara White Marble Field Tile | Polished natural marble, 12×24, 3/8-inch thick | Buyers comparing a specified tile thickness |
| FunStick Marble-Look Vinyl Tile | Self-adhesive vinyl, 12×24 | Nontraditional, removable floor or wall projects |
| Upgraded Subway Tile Peel and Stick | Peel-and-stick backsplash sheets | Backsplash projects, not a standard shower tile |
| AULIGET Faux Stone Backsplash | Peel-and-stick PVC sheets | Kitchen backsplash updates |
Bianco Carrara Polished Marble Tile

This natural Italian marble tile has a white background and soft gray veining, with a polished high-gloss surface and a 12×24-inch format. The listing says one piece covers 2 square feet and describes it for bathroom, kitchen, wall, and floor use.
Best for: Buyers who want natural Carrara marble with a bright, reflective appearance on shower walls. Its large rectangular format can create a streamlined layout with fewer tile joints than smaller formats, depending on the installation plan.
Limitation: The polished finish may be slippery underfoot when wet, so do not assume it is suitable for a shower floor. Confirm the product’s intended application and care requirements before purchase.
Italian Carrara White Marble Field Tile

This listing specifies polished Italian Carrara marble measuring 12×24 inches by 3/8 inch thick. One piece covers 2 square feet, and the straight-edge rectangular shape suits buyers planning a clean-lined field-tile layout.
Best for: Shower-wall projects where natural white marble and a clearly stated thickness are important selection details. Compare the dimensions with the project’s layout and installation requirements before ordering.
Limitation: The product data describes a smooth, shiny polished surface. It does not establish that the tile is a safe or appropriate shower-floor surface.
FunStick 12×24 Marble-Look Vinyl Tile

This is a self-adhesive vinyl product, not natural marble. The package includes 15 tiles measuring 12×24 inches, listed as covering 30 square feet. The listing describes the material as waterproof, moisture-proof, flexible, removable, and easy to clean. It also notes that tiles may arrive rolled and can be flattened under heavy objects before installation.
Best for: Buyers seeking a removable marble-look finish for a project where peel-and-stick vinyl is appropriate. It is not a direct substitute for the natural-stone Carrara tiles above.
Limitation: The supplied details do not establish suitability for a shower installation. Confirm that the product and adhesive are approved for the specific wet area before considering it there.
Upgraded Peel-and-Stick Subway Tile

The supplied product name describes 10 sheets of thicker peel-and-stick subway backsplash tile. Product details provided here do not specify dimensions, material composition, or shower-use guidance.
Best for: Buyers comparing backsplash-style adhesive sheets for a suitable wall project. It is included as an adjacent option, not as a 12×24 natural marble shower tile.
Limitation: The listing information supplied does not establish that these sheets are designed for shower walls or continuous water exposure. Do not treat a backsplash label as proof of shower suitability.
AULIGET Faux Stone Backsplash Sheets

This product is described as 20 sheets of white marble-look PVC peel-and-stick backsplash tile for kitchens. The name identifies it as faux stone, so it is not a natural Carrara marble field tile.
Best for: Buyers seeking a marble-look adhesive backsplash product for a kitchen project, rather than a traditional shower installation.
Limitation: The available details do not confirm shower compatibility, sheet dimensions, or suitability for a wet-area installation. Verify those points with the product information before considering it for a bathroom.
Buying Guide: Choosing 12×24 Marble Shower Tile
Should you choose natural marble or a peel-and-stick look?
Choose natural Carrara marble if genuine stone, natural veining, and a polished finish are priorities. The first two products are the relevant 12×24 natural-stone choices in this list. Vinyl and PVC sheets are different product categories; their marble appearance does not make them equivalent to natural marble tile.
Is polished marble right for a shower floor?
Polished marble can be slick when wet, so treat the listed polished products primarily as wall-tile candidates unless the supplier confirms floor suitability for the intended installation. Shower floors have distinct traction and slope considerations. Ask a qualified installer to assess the exact tile and application.
What should you confirm before ordering?
- Check the exact dimensions, thickness, finish, and coverage per piece or package.
- Order enough material for the planned layout and cuts, using the supplier’s guidance for extra material.
- Confirm the product is suitable for the specific shower surface and installation method.
- Ask about sealing and ongoing care for natural marble; the supplied product details do not specify those requirements.
- Review return and shipping details, especially for tile that may vary in appearance as a natural material.
How does 12×24 tile affect layout?
Large-format rectangular tile can create a less segmented look on shower walls. Before choosing a pattern, account for wall dimensions, corners, niches, plumbing openings, and the installer’s recommended joint layout. A sample or in-person review can help assess the stone’s veining and color variation.
Frequently Asked Questions
Are these 12×24 Carrara tiles real marble?
The first two products are described as Italian Carrara or Bianco Carrara natural marble. The vinyl and PVC products are marble-look alternatives, not natural marble.
How much area does one Carrara tile cover?
Each listed natural-stone tile is described as covering 2 square feet per piece. Confirm the final quantity against the project measurements and planned cuts.
Can I use polished 12×24 marble on a shower floor?
Do not assume it is suitable. The listed Carrara tiles have polished finishes, and the supplied information does not confirm shower-floor traction suitability.
Are peel-and-stick backsplash sheets suitable for shower walls?
The supplied details do not verify that the backsplash sheets are designed for shower use or continuous water exposure. Confirm their approved applications before buying.
