Grand Design Momentum 397TH garage shower mod.

Everyone who owns a 397TH knows when the kids, or any guest use the garage shower, they usually leave behind plenty of water on the bathroom floor. The lip on the shower pan is so shallow, it really does no good. It doesn't even hold the shower liner inside very well. I found a simple solution.
