Hello!
I am making a catalog of ceramic wall/floor tiles, without a basket yet.
I decided to use Prestashop 1.6.1.0, but I have no experience with this system.
The site should have a product filter by various parameters, such as this:

How easy are these things to integrate into the default theme, or is it better to make a custom one for specific tasks?
The design of the site as a whole is not very important now.
Thanks in advance for constructive replies!
