Traditionally, vanities came with matching sinks or basins, but modern bathroom designs have opened up new options to the homeowner, favoring mixed or even contrasting materials. Depending on the bathroom theme and budget, materials can vary from ceramic to formica; granite to glass; to metal or steel.
Different types

Kraus - Clear Glass Irruption Red Sink and Waterfall Faucet, Sale price $240 (CSN Stores.com)
Above counter vanity basins. These are basins that are installed on top of the vanity surface, where the tap holes are installed on the wall, aligned with the water pipes. It’s the easiest to install as they do not need advanced plumbing or holes to mount in place. Best used in bathrooms with low counters. This is similar to the vessel sink basin.
Self-rimming vanity basins. These are drop-in basins that are installed directly onto the vanity, and fits right into pre-cut countertop openings. Rims are flared or wide and are slightly raised above the surface. The raised rim protects the counter’s edges and controls spills.
Under-counter vanity basins. This bathroom basin requires quite an intricate installation as the counter top cut opening needs to be customized to fit the basin. It would only work with strong and sturdy countertops such as granite. It also is the most secure because the basin’s sides are protected from impact. It is best used in a bathroom with minimalist theme.
Semi-recessed vanity basins. These basins are installed like an overhang, designed to provide more space around the vanity.
Inset vanity basins. These basins have the look of an above-counter basin but are similar to self-rimming basins.
Different styles

Porcher - Elfe Wall Mount Bathroom Sink, Sale price $159 (CSN Stores.com)
Wall mounted vanity is typically made of porcelain or even concrete, more commonly used in public bathroom settings, like sports arena bathrooms. The entire vanity is one piece with no separate basin, normally designed with many faucets emptying into a long narrow basin that lets several people wash hands at same time.
Double sink vanities are used traditionally in master bathrooms, where it has two basins on same cabinet just inches apart from each other. This allows two people to use the sinks at same time.
Vessel vanity sinks are set on top of the vanity with the faucet either wall mounted or of the swan-neck type that arches over the basin. The vessel sink itself may be made of ceramic, glass, copper, sometimes even metal or wood. Vessel type of basins can be used in powder rooms of modern homes, where it becomes a focal point of the bathroom, and a good piece of conversation.
Oval basins are of the self-rimming type of basins, where only the edge is raised slightly above counter level and the faucets wall-mounted. Scalloped basins are similar where it has a scalloped edge instead of smooth.
