Toilets come in round-front and elongated shapes, with many different shapes and styles to choose from. Elongated toilets are more comfortable for adults, while round-front styles are popular where space is at a premium. Both round-front and elongated shapes are available in a variety of styles, ranging from contemporary to traditional.
Standard toilet height is around 14 1/2" from the floor to the bowl rim, without a toilet seat. However, toilet bowl height has increased in recent years for the benefit of taller people, those with physical handicaps and/or the elderly. The newest and most popular floor-to-bowl rim height is typically around 16 1/8". Toilets that comply with ADA (Americans with Disabilities Act) requirements must have a 17" to 19" floor-to-bowl rim height, including the seat.
You should also consider the toilet rough-in from the wall, which is commonly 12". Other rough-ins in older homes can be 10" or 14". This is important as many toilet models are available in 12" rough-in, but if you have a unique rough-in (10" or 14"), your selection may be limited. Of course, Sterling offers toilets in many styles, rough-ins and heights for most any installation.
