All water-closets are syphon-jet closets. In the boudoir bathroom on the second floor the bathtub is built to occupy the whole octagonal end of the room, and is constructed of a solid block of marble with a gracefully curved and molded front and a slightly projecting top, above which the wainscoting panels are made continuous for several feet in height, and contain in the center of the tub, at the back side, a large beautifully carved shell, in which a cupid is seated between two graceful dolphins, from whose mouths the hot and cold water supplies gush, being controlled by wheel-handled valves conveniently set in the wall at the end of the tub. In the corresponding bathroom in the other part of the house the porcelain tub has a silver needle-bath canopy frame with rubber curtains and a special silver-plated stool to set in the tub beneath the canopy. The servants' basement water-closets are plain with hardwood, round-cornered tanks with polished-brass brackets, hardwood seats, with polished-brass brackets and polished-brass flush pipes. The mezzanine toilet-room closets have nickel-plated trimmings. The second-floor closets in Mr. and Mrs. Astor's rooms, guests' rooms, and salon toilets have gold-lined closets and plated trimmings. The nursery toilet-closet has silver-plated trimmings. The maids' toilet-closet has nickel-plated trimmings. The closets in guests and public toilets on third floor have silver-plated trimmings. The closets in the servants' toilet-room on the fourth floor have nickel-plated trimmings The bathtubs in Mr. and Mrs Astor's, salon, the guests', public, and the nursery toilets are porcelain roll-rim baths, glazed inside and out, set on marble feet with trimmings plated to match the water-closets. The six servants' bathtubs are roll-rim enameled iron baths, with polished-brass trimmings in basement and nickel-plated trimmings on the fourth floor. Shower baths are provided in Mr. and Mrs. Astor's rooms and in the guests' toilet-room.

All washbasins are 19x15 inches with ground rims. The waste pipes are vertical to the floor and the trap vent branches are horizontal to the wall. The supply pipes are provided with finished valves and air chambers, and the slabs are supported on plated ornamental brass legs and apron holders. The basins in Mr. and Mrs. Astor's rooms, guests' salon, and public toilets are specially decorated. In the basement laundry the set of eight porcelain roll-rim wash-trays is fitted up with bronzed iron standards, marble backs, and nickel-plated fittings. These trays are divided into two sets separately trapped. The four 37½ x 24½-inch porcelain roll-rim sinks in the kitchen and scullery are set on galvanized-iron frames fastened to the wall, and have polished-brass legs. These sinks stand 4 inches clear of the finished wall, and waste through No. 2 polished-brass Tucker grease traps, and have all pipes and fittings of polished brass. These grease traps are connected up in the cellar below in the manner shown in Fig. 3. The two 25½ x 18½-inch porcelain roll-rim basement pantry sinks are fitted up in the same manner. The two German silver first-floor pantry sinks have German silver drain boards and backs, ¾-inch brass hot and cold water pipes placed in the wall with air chambers and swing pantry cocks. They waste through No. 2 Tucker grease traps, with brass waste and vent connection, and all exposed brasswork is nickel-plated. There is in the butler's pantry a No. 6 nickel-plated "Perfection" combined filter and cooler with supply and waste connections. There are in the cellar four 16x24-inch enameled iron sinks trapped and connected with soil and vent pipes, and supplied with hot water through ½ - inch brass pipe. These sinks are to receive the drip from safe and refrigerator wastes, and are all connected up essentially like the one shown in Fig. 3.

The plumbing above described was executed by John Tucker according to plans and requirements of the late Richard M. Hunt, architect.
