What is the actual height of a Convenient Height toilet without and with a toilet seat?

Without a toilet seat: Convenient Height toilet bowl measurement is 20 inches (50 centimeters) when measured from the floor to the top of the toilet bowl rim

With a toilet seat: most of the standard toilet seats are 1 to 1.5 inch high (not including the seat cover) and a Convenient Height toilet Model S with a toilet seat measures 20-21 inches from the floor to the top of any regular style elongated toilet seat.


Does your 20 inch height toilet flush well?

Yes. Actually, it flushes better than most siphonic toilets – and here is why. Our super tall bowl elevation adds some more power to the siphonic flush, based on height and gravity physics; all contents rush downward drain moving incoming water at a naturally increasing flow speed. Convenient Height 20″ toilets have the advantage of added steeper elevation which is naturally good for a stronger siphonic action. Right after the trap way bend, the route is downward all the way into the drain, with literally no resistance at all. The Convenient Height Co. production plant tested Model S toilet with 3 ping pong tennis balls and additional hard items in the bowl at the same time and it flushed well; additionally, it passed the 800g/1.7lbs. hard artificial waste flush testing.

What is a Toilet Rough-In?

How to measure Toilet rough-in
How to measure toilet rough-in: measure from the wall and not the baseboard.

Measure from the wall behind the toilet to the center of one of the floor bolts (the bolts that hold the toilet down). Compare this measurement to the Convenient Height rough-in of 12 inches. If the rough-in at your toilet is equal or longer than 12 inches then our toilet will fit onto your current toilet drain easily. Your rough in can be 13″, 14″ or more (unusual) and as long as it is equal or above 12″ our toilet will fit.

Where are the toilets manufactured?

The Model S 20″ height bowl toilets are produced by a large manufacturing plant in China. The factory has been operating for a decade and is known to provide high quality products. While the Convenient Height uses this large plant, our production line is occupying a small portion of this facility to make the Model S toilets. And since the sizes of 20″ bowl are the first, there is a lot of hand made work involved and this adds a lot more time to the process. As soon as we involve more automation to this new production line, our capacity and speed will grow.

What is an ADA compliant toilet?

It is a toilet that meets Americans with Disabilities Act (ADA) guidelines and ANSI A117.1 requirements. Meeting ADA is not a requirement for private residences. Residential new building and remodels can incorporate the ideas in the ADA Standards as guidelines to improve overall functionality. Individual products must be installed according to ADA Standards to maintain compliance. The Convenient Height toilet exceeds ADA toilet height requirements.

Are Convenient Height toilets easy to install?

Convenient Height toilet installation is same as for any standard floor-bolted toilet. We always recommend using a licensed plumbing contractor for the installation.
