Generally, the collar folks stop with just a collar. The coffin folks usually do a good bit of woodworking and enclose the whole thing in a cabinet and do some tile or whatever on the top. It's personal preference, really, and how much effort you want to put into it. Mine is going to be a coffin style so I'll have a furniture-grade bar to go in the living area of my house. It's the only way I could get SWMBO on board.
