Toilets are generally offered in two configurations, one piece and two piece designs. Our Convenient Height toilet is a two piece toilet that has a separate toilet tank and a toilet bowl secured to each other. Two piece toilets (also known as “close coupled toilets”) are the most common type of toilet available. A Convenient Height two-piece toilet with a bolted installation system provides a sturdy, level connection between the toilet water tank and toilet bowl. Two piece toilet designs are the most popular in the world for residential and commercial installations. Convenient Height Co. offers an attractive, high performance two piece toilet design for homes and offices with contemporary or traditional décor.
