Buying Guide: Key Purchase Considerations
What size and finish fit your space best?
- Small 4 1/4″ tiles offer classic layouts and visible grout lines that accent color; larger 6″ tiles reduce grout impact but require careful spacing.
- Glossy finishes deliver bold color and easier cleaning; matte or textured surfaces hide wear but may show soap scum more readily.
Is porcelain or ceramic better for kitchens and showers?
- Porcelain provides superior moisture resistance, strength, and durability; ideal for floors or high-traffic backsplashes.
- Ceramic is typically more affordable and easier to cut, suitable for walls and occasional backsplashes in residential kitchens.
Should you choose mosaic sheets or individual tiles?
- Mosaic sheets simplify alignment and create consistent patterns for small spaces; individual tiles offer more layout flexibility for complex designs.
- Take note of batch color variations with mosaics; confirm color consistency across sheets when buying in bulk.
What about installation considerations?
- Plan for a moisture-resistant adhesive and proper grout choice. Choose compatible sealants if your area is exposed to splashes or direct water contact.
- Consider sample orders to verify shade and finish under your lighting before full purchases.
