So what’s the best shower caulk for RV shower?

Here’s my top 3 picks:

  1. Geocel 28100V Pro Flex Crystal Clear RV Flexible Sealant
  2. Gorilla 806002 100% Silicone Sealant
  3. Flex Shot Rubber Adhesive Sealant Caulk

If I had to pick just 1 it would be the Geocel 28100V Pro Flex Crystal Clear RV Flexible Sealant because of its durability. It is also sealable, paintable, high-quality, resistant to dirt pick-up and can handle any temperature.

However, I would avoid the BioSeal Translucent Silicone Caulk because of its low consumer reviews.
