Had the same question…so spent many hours searching the forums and internet for a solution. I didn’t like the “From :” or the “$ ” displayed on my grouped products. Finally, I stumbled upon a solution…hopefully this will help you also :
Update the function get_price_html() in Woocommerce\classes\Update class-wc-grouped.php as follows :
// return apply_filters( ‘woocommerce_get_price_html’, $price, $this );
