Note that you can also provide no life support and double the capacity. This implies that the basic air and water recycling system masses about 1 ton. A habitat 'slice' weighs 8.333 tons or 7.5 tons, depending on the ship's SM, averaging about 8 tons, so a standard bunk is 2 tons, and as taking out the life support doubles the capacity, that means the life support is half that, or one ton.

I assume that you are using a five-ton slice for a habitat cabin space, based on how much steerage you get for it, but steerage cargo has at least some life support for it.
