Bath mat

It's actually DRI-DEK. But the link works great.

I like the DRI-TEK I have used it in many areas including boat and home. It also comes in several colors and will out last the camper. Bill

Dri-Tek

Cut to fit. That way you don't have to worry about the floor, just clean underneath every so often. You can find it in one foot interlocking squares in many marine supply houses. Here is my instillation.

I use a cut down yoga mat. Many other purposes also. Tucks under my arm rolled up for campground showers to keep crud of my feet. Also I popped a hole in it so the drain keeps working at regular campground showers and I also stand on it to dry off. Also great to lay on when you have to crawl under truck. And a handy fender protector when your leaning over the hood. Might not work in all wet baths but works in my tiny shower.

It's turning into my temp gun, I keep finding new uses for it.

plastic suction-cup bathmat, int he shape of little "raised" pebbles. High enough to allow the water to drain through... soft on the feet... protects the fiberglass.... easy to clean.

Off the shelf shower mat made of thin foam.

Carpet square cut to fit. Prevents scratches to the fiberglas shawer pan.

None. The fiberglass floor is way easier to clean than anything else is, and there is a drain right there to wash the dirt down if necessary.
