What is a STANDARD toilet?
�There are two rim sizes in the world that are considered STANDARD. The small one is called ROUND and the
large is called ELONGATED. The only other variant from this is the height of the toilet. Most toilets are between 14
and 16 in. from the ground. The other height that is available is called HANDICAP or ADA compliant height. This
height is mandatory for handicap toilets in the U.S. (Mandated in the American Disabilities Act or ADA). The height
of this toilet is between 16 � in and 18 in.
The GJ toilet is actually a new size that we are calling EXTRA-ELONGATED, EXTRA-WIDE.
Is there a GJ toilet for handicap?
�Actually the GJ toilet was designed with the 17 � in. height mandated by the ADA for handicap toilets. So for
practical purposes it is a handicap toilet.
Where can I install my GJ toilet?
�It can be installed in new constructions since it meets all the U.S. standards of operations and water savings. Most
importantly, it was designed to be a simple replacement for existing toilets, both standard or handicap as long as it
has a 12 in. rough in (The 12 in. rough in is standard in the U.S. and other countries)
What is rough in?
�It is the distance from the back wall (behind the toilet) to the discharge hole on the floor. (Aside from the 12 in
rough in standard in the U.S., there are 10 in. and 8 in.)
Can children and other people use it?
�Yes, even though the seat is wider and longer, the width of the central hole in the seat is 8 � in. which is the same
as a normal toilet seat. Handicapped persons can also use it, since it meets the ADA requirements for height.
Who will benefit most from the GJ toilet?
�Most people with a BMI > 40. Especially males, since it gives them 6 extra in. in the front, than a normal
elongated toilet. Handicap people that require a stable wide toilet. People that are extra tall since the GJ toilet
provides a taller toilet in height and also an extra long seat that combined can give them 9 extra in..
How can tall people benefit from the GJ toilet?
�The GJ toilet has a taller bowl plus an EXTRA ELONGATED SEAT that combined provides you 9 extra in. more
than a normal elongated toilet. This translates into comfort.
Is it available for restaurants, hotels or other public places (Institutional)?
�Yes. The GJ toilet is available in two versions. One is for residential use and the other is for commercial use.
(Restaurants, hotels, airports, hospital, universities, etc.)
What is the difference between the residential and the commercial unit?
�The first difference between the residential and the commercial unit is the water supply. In the residential unit the
water comes from a ceramic tank included with the toilet. In the commercial unit the water comes from a flush valve
(not included), that has no tank. The second difference is the seat. In the residential version the seat comes with lid
and the commercial toilet has no lid.
Can institutions benefit from the GJ toilet?
�Yes. Institutions can benefit from a GJ toilet by providing their patrons with more comfort and safety. After all,
institutions like hospitals, universities, public facilities, government offices etc. are normally created to provide
accessible facilities that would enhance their services for their users. Specifically in restaurants and airports
appropriate restrooms are a MUST, since some possible users of their service avoid visiting such places if they feel
they will be uncomfortable or unable to use such facilities.
What is BMI?
�Body Mass Index (BMI) is a mathematical calculation used to determine whether a patient is overweight. BMI is
calculated by dividing a person's body weight in kilograms by their height in meters squared (weight [kg] height [m]2)
or by using the conversion with pounds (lbs) and inches (in) squared as shown below.
Body Mass Index can be calculated using pounds and inches with this equation BMI = (Weight in Pounds /((Height
in inches) x (Height in inches))) x 703
For example, a person who weighs 220 pounds and is 6 feet 3 inches tall has a BMI of 27.5. ex. (220 lbs./((75
inches) x (75 inches))) x 703 = 27.5
