Looking for a particular theme for ecommerce store

I have a client that is looking to sell Kitchen, bathroom cabinets and sinks. It is going to be an e-commerce store. The problem I’m facing is each “product” in this case kitchen, will have many optional add on products to the main product (kitchen).
Here is an example of what I mean:

And here is the webpage to that example:

So in this case users can select cabinet sizes to that specific kitchen. I have not been able to find a theme that can do optional product addons. There are Grouped Products, but I dont think that will work the way most themes have it setup. Is there a theme that is similar to the website link that I posted? Or a theme that can have an option to add many optional product addons to a single product?

Here is a WordPress ecommerce theme for you…
