For a high-end, custom tile company, a professional and clean logo could be described as follows:

Color Scheme: Opt for a palette that reflects sophistication and cleanliness. Think of using neutral colors like white, black, or gray, with perhaps a subtle accent of a color that could represent luxury, such as gold or silver. 

Shape and Form: Consider a minimalistic approach where less is more. A logo could feature a stylized tile or a grid of tiles, symbolizing the product itself. This could be a single tile with a unique shape or pattern, or an abstract representation of tiles forming a clean, geometric pattern.

Typography: Use a modern, sleek font for the company name to convey professionalism. Sans-serif fonts like Helvetica, Futura, or a custom typeface that matches the brand's ethos would be ideal. The text should be legible and placed in harmony with the graphic element.

Symbolism: 

Tile Motif: Incorporate an actual tile or a set of tiles in a minimalist form. This could be a square or rectangle that's slightly offset to show depth or texture, suggesting the dimensionality of tiles.

Clean Lines: Sharp, clean lines in the design would reflect the precision in your work. 

Negative Space: Use negative space cleverly to create an additional layer of meaning or to highlight the custom aspect of your work, perhaps by subtly forming a letter or symbol within the tile's design.

Simplicity: The logo should be simple enough to be recognizable even when scaled down for business cards or up for signage but complex enough to convey the bespoke nature of your products. 

Versatility: Ensure the logo looks good in monochrome for practical uses like invoices or when printed in black and white, ensuring brand consistency across all platforms.
