Common bathroom fixtures:

• A lavatory sink is a bathroom sink that sits within a cabinet fixture.
• A pedestal sink is a free-standing sink without a cabinet base.
• A utility sink is a large, deep sink typically found in laundry or utility rooms.
• A shower/bath is a tub or small enclosure used for bathing. Can either be free-standing or built-in.
• A whirlpool is a popular option for tubs. Built-in jets force water around tub. Great for relaxing.
• A steam shower is a nice luxury feature similar to a shower, except jets emit steam instead of water.
• Bidets aren't common in the U.S, but are usually found next to toilets in Europe. Used for personal cleansing.
