I have a tiny combination toilet and shower.

There is a curtain to prevent splashing water from reaching the toilet
area but there is nothing on the floor to restrict the water to the
shower area.

It doesn't have to be over 1/2" tall, just enough to prevent water
creep.

I am thinking of caulking a piece of PVC pipe cut down the middle type
of fix.

Is there a product out there?

Why don't you put down a marble saddle?
