Cheap sinks can be made out of different materials, depending on the type and style of the sink. Some of the most common and affordable sink materials are:

Stainless steel: This is a popular choice for kitchen sinks because it is durable, water-resistant, scratch-resistant, and easy to clean. Stainless steel sinks are also resistant to rust and corrosion, and can match well with stainless steel appliances. However, stainless steel sinks can be noisy when you drop dishes or utensils into them, and they can also show water spots if not wiped dry.

Porcelain: This is a classic choice for bathroom sinks because it has a smooth and glossy surface that is easy to clean and maintain. Porcelain sinks are also available in a variety of colors and styles, and can add a touch of elegance to your bathroom. However, porcelain sinks can chip or crack if you drop heavy or sharp objects into them, and they can also stain or discolor over time if not properly cared for.

Composite granite: This is a type of synthetic material that is made from a mixture of granite and resin. Composite granite sinks have a natural look and feel that can complement your countertops and cabinets. They are also resistant to heat, scratches, stains, and impacts. However, composite granite sinks can be expensive compared to other materials, and they can also require regular sealing to prevent fading or cracking.
