The Best Caulk for Showers and Tubs in 2023

Gorilla’s adhesives tend to be a step above the competition, and the same is true for this clear sealant caulk. This 100 percent silicone caulk adheres to most surfaces easily to create a mold- and mildew-resistant barrier. It remains flexible throughout its life, and it won’t shrink or crack like some siliconized caulks might. It dries in just 30 minutes, making it useful for quick repairs or even full bathroom installations.

During testing, we found Gorilla Clear 100 percent Silicone Sealant Caulk to be a top-quality product. It applied easily and created a strong bond for the shower surround. Once dry, we found it was barely noticeable, and the fact that it remains flexible and won’t yellow leads us to believe it’ll stay unnoticeable. While it’s not paintable, this product will work on any seam that needs to be waterproof but doesn’t need a coat of paint. We also liked that it flowed well, was easy to tool, and was not too sticky to tool with a wet finger.
