Before your kids get squeaky clean in the tub, let them get colorfully messy. This easy DIY bathtub paint brings a spectrum of fun to bath time!

Bathtub Paint

1 divided dish, plastic egg carton, muffin tin, or plastic container

50 mL (1/4 cup) soap: hand soap, body wash or leftover shampoo (even better if it’s tearless)
50 mL (1/4 cup) cornstarch or tapioca starch
15-45 mL (1-3 tbsp) water
3-4 drops of food coloring


  1. Combine the soap and starch
  2. Add water a little bit at a time until you get the paint consistency you’re looking for. Too runny? Add more starch
  3. Add food coloring until you achieve your desired shade

Tip: Remove the bath paint from the walls and tub after each use with a paper towel.

Tip: Capped, this mixture should last several months but will need to be shaken or stirred before use.

Note that some bathtub materials, such as travertine tile or grout between tiles, may become stained with this paint. Consider painting and rinsing a small section of the tub near the drain or the along the bottom of the wall yourself before letting the kids use all surfaces as a canvas. You may want to limit them to only painting the tub portion.
