The best towel racks for small bathrooms are compact towel bars and space‑saving hooks. A 12-inch towel bar is ideal for a single bath towel, and 8 or 9-inch bars fit well beside a sink for hand towels.
If you have very limited wall space, a 6-inch double towel bar adds more drying room in a small footprint. Swivel towel hooks are another good option because they take up minimal wall space and can hold multiple towels or robes on separate arms.
What is the difference between overall length and center-to-center of a cabinet pull? Where can I find this information?
Overall length is the total length of the pull. Center-to-center is the distance between screw holes on the pull body. The center-to-center distance is how you determine what size pull you need to swap out existing cabinet hardware.
This information can usually be found in the image carousel (the collection of images on a product page). It might also be listed as product dimension length with other details such as finish and material. Lastly, you can find overall length in the specifications section on the product page.
