Angle stops are to be shut off in case of an emergency or repair and are generally not designed for daily on and off useage. The difference between a "straight stop" and an "angle stops" is that the "angle" stop changes direction by 90 degrees while a straight stop is like most valves and does not change direction.
An acrylic panel can be used in place of tile or marble. When an acrylic tub is mounted in a 3-wall installation.
The apron, or skirting, a decorating portion of a bathtub that covers the rough-in area from the floor to the top rim of the tub. It is often sold separately from the tub.
The mechanism that controls the flow of water into a gravity-operated toilet tank. The ballcock is controlled by the float mechanism floating in the water in the tank. When the toilet is flushed, the float drops and opens the ballcock, allowing water to enter the tank and/or bowl. The float rises as the water level in the tank is restored, and shuts off the ballcock when the tank is completely filled. Also referred to as a float valve.
Refers to the size of a ball that can pass through the trapway of a toilet. Standards are established based on minimum-sized ball passage. Ball passage also relates to trapway size. Generally speaking, the size of the trap will be 1/8 larger than the maximum-sized ball that can pass through it.

System used in our pressure assisted toilets Air trapped inside an enclosed tank is compressed as water refills the tank after it is flushed.. When the toilet is flushed, the air releases like a tightly wound spring, surging the water into the bowl at high velocity. The crest of this torrent empties bowl contents in less than 4 seconds, and pushes them through the drain line.

A toilet in which the tank and bowl are manufactured as a single vitreous china fixture. Typically, one-piece toilets have a lower profile than two-piece toilets.
The vertical tube inside a toilet tank (usually part of the flush valve) that directs water into the bowl in case the ballcock malfunctions. If the ballcock does not shut off properly, water will drain through the overflow tube into the bowl, and flow harmlessly over the dam and out the drain. This prevents potential water damage caused by the tank overflowing and indicates to the user that there is a problem by a "constant running" condition. On most toilets, the overflow tube also has a refill tube flowing into it. The refill line directs water from the ballcock through the overflow tube to the bowl after the siphon break.

Installation where lavatory is fit flush with countertop.

A device to prevent water standing in a basin or container from being drawn back into your water supply if there is a complete loss of water supply pressure. A siphon can occur if the end of a hose, hand spray or spout is below the liquid's surface, pulling contaminated water into the building's water supply pipes.
