Frequently Asked Questions
Everything you need to know about ordering, installing, and caring for natural stone mosaics.
01
Product & Material
What are natural stone mosaics made from?
Natural stone mosaics are crafted from genuine quarried materials such as marble, limestone, dolomite, and other decorative stones. Each piece is cut into smaller formats and assembled into mesh-mounted sheets that create intricate mosaic patterns. Because the material is natural, variations in color, veining, and surface texture are expected and contribute to the beauty of the installation.
Do natural stone mosaics vary in color and pattern?
Yes. Natural stone mosaics will display variation in tone, veining, and movement because they are cut from natural stone blocks. These variations are part of the material’s character and are considered a desirable feature in luxury stone installations.
What is a dye lot of natural stone?
A dye lot refers to a specific production batch of tile or stone that was manufactured or processed at the same time. Because natural materials and finishing processes can vary slightly from batch to batch, tiles from different dye lots may show subtle differences in color or tone. For the most consistent appearance, it is recommended to purchase all required material from the same dye lot whenever possible.
Where can natural stone mosaics be installed?
Natural stone mosaics are commonly used for backsplashes, bathroom walls, shower floors, niches, shower walls, feature walls, floors, and decorative accents throughout residential and commercial interiors. When properly installed and sealed, they perform well in wet areas such as showers.
Can natural stone be used outdoors?
Many natural stone mosaics are suitable for exterior walls and floors in mild climates. However, natural stone is porous and can be damaged by freeze-thaw cycles, so outdoor use in climates with freezing temperatures is not recommended unless the specific product is rated for that application. Each product page includes an applications table specifying whether outdoor use is appropriate. When in doubt, contact us before ordering.
Is natural stone safe for pool surrounds or submerged applications?
Most natural stone mosaics are not recommended for fully submerged or pool applications. Prolonged submersion can cause certain stones to absorb water, shift in color, or deteriorate over time. If you are considering a pool or water feature application, please contact us to discuss material suitability before placing an order.
What is the difference between honed and polished stone mosaics?
Honed stone mosaics have a smooth matte finish that creates a soft, understated appearance. Polished mosaics have a reflective surface that enhances the depth, color, and veining of the stone. Both finishes are popular in luxury mosaic tile installations depending on the design aesthetic.
Do you have a physical showroom?
The Mosaic Shop is the natural stone mosaic collection of Ruben Sorhegui Tile, located in Naples, Florida. Our full mosaic collection is available to view at the Ruben Sorhegui Tile showroom, where a dedicated Mosaic Shop display showcases our natural stone designs. You are welcome to visit in person or order samples through our website to evaluate the material in your own space and lighting conditions.

Installation & Setting Materials
How are natural stone mosaics installed?
Natural stone mosaics should be installed by a qualified tile professional using a premium white thinset mortar over a properly prepared surface. Mosaic sheets are carefully aligned to maintain consistent spacing and pattern, then grouted once the mortar has cured. A dry layout is strongly recommended to ensure an evenly balanced appearance of natural veining. After grouting, a penetrating sealer should be applied to protect the stone and grout joints.
All installations should follow the guidelines established by the Tile Council of North America (TCNA).
What grout should be used with natural stone mosaics?
For natural stone mosaics, an unsanded grout is generally recommended for joints under 1/8 inch, and sanded grout for wider joints. Color selection matters — for lighter stones, a white or light-toned grout is typically preferred to avoid color contrast that can make the joints appear prominent over time. A high-quality polymer-modified grout will provide the most durable and consistent results. Your installer should confirm the most appropriate grout type and color based on your specific product and application. Sealing the grout joints after installation is recommended to protect against moisture and staining.
Can mosaic tile be installed in showers?
Yes. Natural stone mosaics are widely used in shower walls, shower floors, and decorative niches. Proper waterproofing, installation methods, and sealing are essential to ensure long-term performance in wet environments. Mosaics containing Mother of Pearl or Rivershell should not be used for shower floors or in fully submerged wet areas.
Does The Mosaic Shop offer installation services?
The Mosaic Shop does not provide installation services. We recommend working with a qualified tile professional in your area who has experience installing natural stone mosaics. Searching for local tile installers through Google and asking your contractor or designer for recommendations is often the best way to find a skilled professional near you.
03
Care, Cleaning & Sealing
Do natural stone mosaics need to be sealed?
Yes. Because natural stone is porous, a penetrating sealer should be applied after grout has fully cured. Sealing helps protect the stone surface and grout joints from moisture and staining.
Do I need to seal before grouting or only after?
Both. A penetrating sealer should be applied to the stone surface before grouting to prevent grout from staining the face of the tile during installation. Once the grout has fully cured, a final coat of sealer should be applied to protect both the stone and the grout joints. We recommend STAIN-PROOF® penetrating sealer, available through our shop.
How do you clean natural stone mosaics?
Natural stone mosaics should be cleaned with a pH-neutral cleaner designed specifically for stone surfaces. Harsh or acidic cleaners can damage marble and other natural stones and should be avoided. We recommend the FILA Natural Stone Neutral Cleaner.
What cleaning products should be used on natural stone tile?
Only stone-safe, pH-neutral cleaners should be used on marble and natural stone mosaics. The Mosaic Shop offers FILA Natural Stone Neutral Cleaner, a professional-grade natural stone cleaner formulated to safely maintain stone surfaces.
How often should natural stone mosaics be resealed?
Most natural stone installations should be resealed every one to three years depending on the environment and level of use. Areas exposed to frequent moisture may require more frequent sealing.
04
Ordering & Product Availability
Can I order mosaic tile samples before purchasing?
Yes. Ordering samples allows you to evaluate the stone’s color, finish, and pattern before committing to a full installation. Viewing samples in your project’s lighting conditions helps ensure the material aligns with your design vision.
How much mosaic tile should I order for my project?
It is recommended to order at least 10–15% additional material to account for cuts, layout adjustments, and potential breakage during installation.
Do you offer custom mosaic design?
Custom mosaic designs may be available depending on the material and pattern requirements. Designers and architects working on specialized projects are encouraged to contact The Mosaic Shop at sales@themosaicshop.com to discuss custom mosaic possibilities.
Can I modify my order after it has been placed?
Orders can be modified if they have not yet been processed for shipment. Please contact The Mosaic Shop at orders@themosaicshop.com as soon as possible to make changes on an order.
What happens if I need to reorder material later?
We recommend ordering all required material at one time. Natural stone is cut in production lots, and material ordered at a later date may come from a different lot with slight variations in tone, veining, or surface character. Additionally, prices are subject to change and reorders will reflect current pricing at the time of the new order. Certain products may also become unavailable between orders.
Can I place an order on hold or delay my shipment?
Once an order has been confirmed and processed, materials are prepared for shipment promptly and cannot be placed on hold for future delivery. If your project timeline requires a delayed shipment, we recommend contacting us before placing your order so we can discuss options and current availability.
Can I speak with someone about my project before ordering?
Absolutely. Our team is happy to assist with product selection, quantity estimates, and general guidance. Reach us at info@themosaicshop.com or through the contact form on our website. For trade inquiries, contact sales@themosaicshop.com.
