By default in WooCommerce the product description of a product sits inside the ‘Description’ tab, with the Short Description displayed more prominent alongside the product. Here is how to swap that order and display the product content at the head of the page and remove the tab description (…as it will display twice).
So in the above I want to swap the Product Description and make it more of a Sales Page, I realise that you could do this with a product short code on a sales page but in this instance it needs to be done on the actual Product Page.
Add this in your functions.php file
So now above the content order is swapped and the description tab is removed, just need some CSS styling to tweak the layout, this also now makes it easier to use with a builder such as Beaver Builder.
