Overview

About this product

Quarried natural marble in blue mosaic format, MSI Montauk Blue Subway Tile 4x12 carries the slab-to-slab variation that defines real stone work, in mesh-mounted sheets sized for direct shower and feature install. The dimensional variation that mesh-mounted construction makes possible reads as deliberate craft rather than tolerance. Color holds its read under both task lighting and ambient, the kind of consistency that distinguishes designer-grade mosaic from value-grade alternatives.

It rewards close attention in the way premium tile is supposed to, joint resolution, color consistency, the kind of dimensional read that holds across full-wall installs and not just the showroom sample. What separates this kind of mosaic from the alternatives is the joint resolution, color consistency, and the dimensional read that holds across full-wall installs.

Questions

Tile FAQ

Will Montauk Blue Subway Tile 4x12 work for my project?

Montauk Blue Subway Tile 4x12 is wall tile & backsplash from MSI. The full specs are listed in the Specifications above. If you would like a specialist to confirm it suits your room, subfloor, or use case before you order, reach out and we will review the details with you.

Is this tile rated for floors, walls, or wet areas?

Check the use rating in the Specifications above, since many porcelain tiles work on both floors and walls while lighter wall tile is meant for vertical use only. For showers and floors, look at the slip rating too.

Can it be used outdoors?

Frost-rated porcelain can move from indoors to patios and pool decks, while ceramic and decorative wall tile are usually indoor only. Confirm the freeze-thaw rating for your climate before ordering.

What about slip resistance?

For wet floors and showers, choose a textured or matte finish with a higher DCOF or R rating. Polished tile looks beautiful on walls and dry floors but can be slick when wet.

Do I need trim, and how much overage?

Order coordinating bullnose or trim for finished edges, plus grout in your color. Add about 10 percent for cuts, and more for mosaics or patterned layouts that waste a little material.

Common Questions

Ordering & Support

Is this suitable for my application?+

Each product lists its wear layer, finish, and use ratings in the Specifications above, so you can match it to residential, commercial, or wet-area use. If you are not sure it fits your project, our specialists will review the details and confirm the right product before you order.

What is the lead time?+

Most in-stock orders are processed within 1-3 business days, then ship by ground or LTL freight depending on size and weight. Transit time varies by destination, and any made-to-order item shows its expected production window at checkout.

Do you price-match the trade?+

Yes. Builders, designers, and developers unlock trade pricing through our Developer Program. Apply once and your account receives member pricing across categories, plus dedicated support for large-volume orders.

How do I make sure the color matches?+

Screens and lighting vary, so our specialists will confirm the exact color, finish, and texture details with you before you commit. For larger orders we pull from the same dye lot where possible, and a small overage helps keep everything consistent.

What if my freight arrives damaged?+

Inspect your shipment on arrival. If anything is damaged, photograph it before unloading, note it with the LTL driver on the delivery receipt, and report it to us the same day, so we can file the carrier claim and ship free replacements.
