For bathroom and shower tile combinations, consider contrasting colors or patterns to create visual interest. Use mosaic tiles for an accent wall or niche and large-format tiles for the floor to reduce grout lines. Combine different textures, like matte wall tiles with glossy floor tiles, to add depth. Ensure the tiles are suitable for wet environments and match the overall bathroom design theme.
