Well to the forum Mr. & Mrs. ColoradoMTB11!
If by "build your own" you mean taking your designs to a custom builder, then yes, you should be able to get whatever you want in the way of a bath (within size limitations of a class b).
If you mean you plan a purely do-it-yourself build, then you will be limited by your resourcefulness and parts availability. Others on this forum have done their own build and will likely be along to comment from a position of authority on this question.
