When designing a bathroom, deciding whether to purchase a pre-made vanity or order a custom one can be difficult. Both of these options have positive and negative aspects. For pre-made vanities, the cost will remain low and the project can be finished faster, but you will be limited to the designs and styles available in whichever store you choose. Custom vanities allow much more creativity and specification; you will have the oppertunity to create the unique vanity you envision in your space. The negative here is that this can cost roughly 40% more than if you were to buy a pre-made alternative.
When deciding between custom and pre-made vanities the most important factor is the size of your bathroom. If you are working with a larger space, a custom vanity is more appropriate for your project. Smaller spaces are more easily matched with pre-made vanity, as the average pre-made vanity (even double sink options) are designed for smaller bathrooms. When you are dealing with a large square footage, a custom vanity will allow you to make better use of your space for you specific needs and wants.
