When sourcing wooden mosaic tiles, the price is primarily driven by wood species, backing material, and craftsmanship. Premium hardwoods like Teak, Walnut, or Oak command higher prices due to their natural durability and grain patterns. Ensure the wood has been kiln-dried to a moisture content of 8%-12% to prevent warping or cracking after installation. For the backing, nylon mesh is the standard for easy installation, while solid wood backing is more expensive but offers better structural integrity. Always request a Grade A rating for surface finish to ensure no visible knots or splinters.
