Trough sinks come in all sizes, colors, and shapes, but the main materials used in constructing them are stainless steel and solid surface.
Stainless Steel - This material is great for a trough sink as it's extremely strong. It's impervious to vandalism and it's long-lasting. Despite being metal, it is resistant to rust because the material is added with a thin chromium oxide layer. Although stainless steel is excellent for industrial applications, there are homeowners who love the way the material looks. Also, a wall-mounted trough sink made of stainless steel can blend in regardless of the bathroom's style or aesthetic appeal.
Solid Surface - A solid surface can have a stone's appearance as it is composed of naturally-occurring pigments and minerals that are mixed with a binding agent. It can have anti-fungal properties and water resistance ability, so it is a great material for sinks. A solid surface is often formed into modern, sleek designs. It also comes in a wide variety of colors.
