How do you reduce the bubbles bath tub?

To reduce bubbles in a bubble bath, use less bubble bath product, as a smaller amount will produce fewer bubbles. Additionally, add the product slowly while filling the tub to minimize agitation. Opt for bubble bath formulas designed for low sudsing, and ensure the water temperature isn't too hot, as higher temperatures can increase bubble formation. Lastly, consider adding oils or bath salts that have less foaming potential.
