How to potty train my 3 yrs old girl?

I started by letting her without diaper after school and teach how to pee at the shower area, I put a bucket of water there so she can wash her hand and clean her feet from urine. She thinks it's fun so she will do it by herself while I was cooking in the kitchen, but bcos it's a bit messy, sometimes she comes out without cleaning her feet, so I teach her to climb up the toilet seat (with ikea potty seat on it), now she is well trained, but we still help her to clean her private area for hygiene purpose
