There is a wide variety of choice available when it comes to the sizes, forms, and materials of bathroom vanities. The following are some factors to take into consideration:

Sizes:

Single vanities are the smallest option, often measuring between 18 to 60 inches broad. This makes them the ideal choice for bathrooms with little space. They are an excellent option for use in bathrooms or powder rooms that are on the smaller side.
Double vanities are larger than single vanities and come equipped with two sinks. They normally range in width from sixty to seventy-two inches and are an excellent option for larger bathrooms as well as shared baths in master bedrooms.
Custom vanities: If you have a particular size in mind for your vanity, or if the shape of your bathroom isn't conventional, you might want to think about getting a custom vanity.
Shapes:

The most typical configuration for a bathroom vanity's shape is a rectangular one.
The addition of round vanities to a bathroom can give the space a cosier and more refined appearance.
Corner vanities are an excellent option for bathrooms that are either on the smaller side or want to create the illusion of having more space in their existing layout.
Materials:

Wood: Vanities made of wood are timeless and can bring a sense of cosiness to a bathroom. They can be purchased with a variety of coatings and designs, such as classic, contemporary, or even old-fashioned ones.
Laminate: Vanity tops made of laminate are a low-cost choice that are also simple to clean and maintain. They are offered in a variety of hues and patterns so that they can accommodate a wide variety of design aesthetics.
Stone: Stone vanities, such as marble or granite, lend an air of opulence to a bathroom. Marble and granite are two examples. They are long-lasting and resistant to the effects of dampness, but the cost of purchasing them may be higher than that of alternative possibilities.
Glass: Glass vanities are a contemporary option that can give the impression that a bathroom is larger than it actually is. They are simple to maintain and clean, but their longevity may not compare favourably to that of other materials.
