Anything that is all of one piece is likely to prove more lasting than the other kinds, in the lavatory. There are various combinations, some of them including handsome marble tops, but basin and top should not be separate. If the wall is tile, the back that fits to it is not essential; but if the back is used, it should be of a piece with the s]ab, bowl, and apron, to avoid ugly cracks and breakage. The bracket form is usually regarded as most convenient, as legs are often in the way, unobtrusive looking as they may be. Another method of attachment is by a concealed wall hanger. The pedestal design is somewhat more artistic, but additionally expensive not only in the beginning, but afterward in the event of damage. Lavatories in enameled iron cost from $16 to $75, including fittings and pipes above floor. Some people like running water in their bedrooms, and a private lavatory is certain to be appreciated by visitors. Objection has been made that the introduction of plumbing into the bedroom affords a new source of sewer-gas poisoning, but with modern materials and workmanship this need not be feared. For the bedroom the supply man will recommend the pedestal arrangement, costing about $50; but less expensive forms might serve. Of course every additional outlet, such as this, increases the piping bill and outlay for labor.
