The choice of vanity unit is not as simple as it first appears. Differing materials may be used depending upon the design criteria, the purpose of the building and likely wear and tear characteristics.
Granite feels luxurious whilst glass feels modern and minimalistic but both have fabrication limitations. Solid Surface materials provide a look and feel similar to granite but it can be fabricated in a wider range of configurations. High-Pressure laminate vanity units can be manufactured with integral upstands and downstands and have a much wider range of colour choices available but may not be as resistant to heavy wear and tear whilst pre-fabricated troughs are very efficient in terms of space requirements and splash retention.
