Add 1/3 of a cup or more of the soak to your bath while the bathtub is filling with water. Relax, and enjoy your amazing soak.
If you're using a Bubbling Soak, wait until the tub is at least 4 inches full prior to filling, then add the soak directly to the water coming out of the faucet.
For even more bubbles, add the soak to a loofah, sponge cloth or even into a sock then hold it under the running water. This allows the bubbles to gain more air, making larger, longer lasting bubbles.
