There are four basic washroom fixtures: the shower, tub, sink, and toilet. Bathrooms which include these four fixtures are typically called "four piece bathrooms." There are several other washroom fixtures, but each is related to these four basic types. All washroom fixtures are available in a wide variety of styles and finishes. The inclusion of additional fixtures usually depends on budget and space.
Although not technically a different fixture, the most common addition to the four basic washroom fixtures is a second sink. This is often called a double or dual vanity. Two sinks are often more convenient for a couple, especially if both individuals wash and dress at the same time each day. The two sinks are either installed on a single countertop or on two individual vanities.
Every bathroom or washroom has a toilet. There are hundreds of styles, including low energy and low water toilets, dry toilets, and toilets made of special materials. Some toilets also have built-in features like a night light, a sensor to lift the lid, or a built in spray system.
The companion fixture to the toilet is the bidet. A bidet is similar in size to the toilet and also has a basin which fills with water. It typically has one or two water sprays, which are used for cleansing in place of toilet tissue. Bidets typically match the finish and style of the toilet.
Although more commonly found in public restrooms, another type of washroom fixture is the urinal. This is used exclusively by males for urination. It is mounted on the wall and includes a basin, drain, and water spigot.
A shower may be stand-alone or a shower and tub combination. Showers vary in size and construction from a simple stall design, about three feet square (1 square meter) to much larger. Some showers include multiple shower heads, sauna capabilities, lights, and even a waterproof television and stereo. They may be constructed of acrylic, ceramic tile, marble, stone, or wood.
Tubs can be built in, as in the shower and tub combination and some types of jetted tubs, or stand-alone. A stand-alone tub is not connected to the wall, although it might have a built in surround. Tubs can be quite large, holding hundreds of gallons of water and can be made out of many different materials, including cast iron, acrylic, marble, bronze, and porcelain.
