Vitreous glass tiles come in a wide range of colours from the brightest reds and oranges to some really subtle shades. They are easy to cut using tile nippers, and can be used for both indoor and outdoor projects. They can be used on walls and floors in domestic bathrooms but are not suitable for areas exposed to heavier traffic. The tiles come on paper-faced sheets or on mesh. They measure 20mm x 20mm and there are normally 225 tiles although this can vary very slightly according to manufacturer. We also supply these tiles in smaller 25 tile sheets.
