What to Look for in an Under Sink Organizer
Size The biggest factor you should consider when selecting an under sink organizer is its size, as you want it to fit nicely under your sink. Be sure to measure accurately, so you don’t find yourself stuck with a product that's too big or too small.
Storage Under sink organizers can help you save a lot of space in some cases. However, some are designed to hold more than others. Consider the kinds of items you typically store under your sink, as well as how big they are and how easily you want to be able to access them.
Features Some under sink organizers offer simple shelving for storage, while others boast features like baskets that slide out and spaces designed to hold specific items such as hair tools. Some are also expandable and/or the shelf heights can be adjusted to get the right fit for your items and work around pipes.
