A bathroom sink vanity has all of the same uses as a standard sink, only it has more storage space. As one or more people can use a bathroom sink vanity, two design options are available: single sink and double sink. Double sink vanities, of course, are longer and have two sink basins, but single-sink bathroom sink vanities with longer tops are another option if you're looking for more space for yourself. In terms of space, many of your standard bathroom items can be stored in the cabinets in these fixtures. Smaller cabinets, for example, are reserved for toiletries and hair tools, while the larger cabinets can hold cleaning supplies or even towels.

The basic design of any bathroom vanity includes a sink basin and a cabinet. In general, the cabinet is wood, while the basin is a porcelain material. As the cabinet needs to be protected from the moisture of the sink, often a stone counter top is added. This counter top is either made from real stone, such as granite or marble, or a man-made, altered stone. Other options include matching the counter to the sink basin. As a mirror is another piece common to many bathrooms, a set for a bathroom sink vanity may include a matching mirror.

Aside from use as a sink, another important quality for all bathroom vanities is storage space. The cabinet may be decorative, but it needs to have enough space. In general, one of these cabinets has doors or drawers of various sizes to store hair tools, cosmetics, toiletries, and towels. But bathroom sink vanities are designed in classic - or wood - and contemporary styles. Both have enough storage space but, with separate vanity cabinets in many metal and glass contemporary vanities, where and how you store things will vary with each style of vanity.

If you're considering adding a bathroom vanity, various retailers of bathroom furniture carry classic and contemporary bathroom sink vanities. Consider the amount of space available in your bathroom for a vanity and find one that fits - in both size and style - your bathroom.
