Definitely.
The more details/product info/finishes/etc. you put into your pages, the greater keyword reach you will have.
The competition for generic keywords is stiff. The more variety you have to your content, the more you'll be able to capture longer search phrases.
As an example: Try "Indianapolis Glass Tile Master Bath" in Google.
You'll find 1/3 of the first page results lead to me, or things I have written. You never know what someone might enter as a search phrase. The more content you have, the more keywords you hit.
