How can I customise a woocommerce store page without plugins

Quite new to wordpress and the first time I’ve set up a woocommerce store (almost, with your help).

I would like to add options to the store page for example product categories and price ranges etc without additional plugins as they seem to alter the search results page.

The page with the cbd products is mine.
The circled areas on the other page are similar to what I need to include.

Hope someone can help me!
