Product page with Woocommerce color filter I the sidebar ?

I try to make something, not really extraordinary and I am not able.
This is what I would like:

A shop page with a small design and presentation text on the top of the page and products below. I also need a right sidebar with Woocommerce price filter.

1- I tried to add the text in the category page and add a icon, that work, but this technique are not customizable enough. I am not able to make a title and change the size/font of the text.

2- I tried to not us the real shop page and create a normal page with the avia layout builder and use it as shop page. I can make my text and design like I want and use the product grid to show my products. All is ok except the Woocommerce price filte didn’t work.

Is it normal ? Somebody have a other solution of some hints for me ?
Thanks,

Alain
