Potty training

My baby is 20 months old, is it too early to potty train? She doesn’t really say words yet but she HATES diaper changes and I know that she recognizes when she pees because for the last week every night when we get out of the bath (part of her bedtime routine) I dry her off and before I can grab a diaper she will try to run into our hallway and then stop, put her legs together like she’s trying to hold it, and watches herself pee all down her legs. It literally happens so fast I cannot get a diaper on her most night before she’s intentionally peeing on the floor. She used to just pee in the bath but it’s apparent that she’s holding it through bath time so she can pee on the floor. She thinks it’s funny and splashes in her pee puddle.
