New for September 2023! SaniCOMPACT C4, a self-contained dual flush toilet system with smaller profile than the classic, 4th generation SaniCOMPACT.

Please note BOTH the SaniCOMPACT and SaniCOMPACT C4 share exactly the same motor and specifications. The difference is only in the porcelain design and height, as well as the location of the flush button.

The SaniCOMPACT C4, although significantly less expensive, is essentially the same toilet as the SaniCOMPACT Classic (4th Generation), but comes in a standard height rather a Comfort height.

Options Include:
Descaler: cleaner, removes hard water deposits in macerator

Specifications & Installation Manual:

Product Description:
Both the SaniCOMPACT  and SaniCOMPACT C4 are self contained systems that are used to install a half-bathroom up to 9 feet below the sewer line, or even up to 100 feet away from a soil stack.  The SaniCOMPACT product line can handle the effluent from a toilet and sink for residential applications.

Self-Contained Toilet

Do away with the need for a separate flush tank with this self-contained toilet. The Saniflo SaniCOMPACT | One Piece Unit is equipped with a macerator and impeller and completely ejects toilet waste when the button is pressed to keep the toilet area sanitized after every use.

Minimized Water Usage

This is the perfect toilet for the environmentally conscious consumer. Utilizing just 1 gallon or 1.28 gallons of water per flush, this water-efficient toilet refills the bowl with just the required quantity of fresh water to keep water usage to a minimum.

Fit for Small Spaces

The Saniflo SaniCOMPACT One Piece Unit models are a good choice for half-bathrooms in a garage, bedroom, or under a stairway. Fit for small spaces on the upper or lower floor, in a basement or in an attic, these units can pump vertically up to 9 feet from sewer lines and horizontally up to 100 feet from soil stacks. The discharge elbow of the system rotates 360 degrees to give added flexibility during installation and allows you to connect the unit to a sink to minimize plumbing requirements.

Sleek Look

This Saniflo toilet completes the beauty of a modern half-bathroom. There is no separate flush tank, letting this stylish toilet blend well with the decor of a contemporary half-bathroom.

Different Heights: Comfort vs Standard

The SaniCOMPACT Classic (4th generation) is a higher toilet seat at 18.5" which is considered Comfort height. 18.5" toilet height has picked up popularity in new construction builds due with older people and taller adults, but is also an effective handicap height toilet.

The SaniCOMPACT C4 (new for September 2023) is a more compact... er... COMPACT! Sitting just 16.5" in height it's slightly taller than the 16" Standard toilet height.

How It Works: 
The SaniCOMPACT models need no gravity flow tank as the flushing action and macerating pump cycle is automatic after pressing a push button on top of the bowl (side for C4 model).  The flushing mechanism is electrically timed to allow water to pass through the toilet.

By pressing the push button, this activates a timer and a solenoid valve in order to fill and wash the sides of the bowl.  The motor starts and the waste and paper are sucked inside where it is macerated and pumped away.  The motor stops after approximately 10-15 seconds and the timer programs the refill of the bowl with fresh water.

The inside of the SaniCOMPACT comprises of a pressure switch and circuit board assembly, which starts and stops the unit, and the motor, which drives the blade and the pump.  The motor is sealed for life in an oil filled enclosure.  A common spindle/shaft drives the impeller and the macerator blades. The moving parts therefore are kept to an absolute minimum. Water and organic waste matter, enter the chamber and are reduced to slurry as the macerator blades rotate at 3600 RPM. The reduced solids are picked up and the impeller mounted beneath the motor ejects the waste. The unit pumps the effluent upward to 9 feet and/or 100 feet horizontally (with gravity fall).

The discharge elbow on the back of the SaniCOMPACT models can be rotated 360 degrees to fit any type of installation required.  A non-return valve, which comes already assembled on the discharge elbow, prevents back flow into the unit. 

The SaniCOMPACT and SaniCOMPACT C4 sport a forced main and do not need to be vented and connected to a vent stack.  Other fixtures may need to be vented as per local plumbing codes. It is also highly recommended for the macerator/pump to be connected to a Ground Fault Interrupter (GFI) circuit.

Plumbing Code Certified:
The SaniCOMPACT and SaniCOMPACT C4 have been certified to American and Canadian Standards.  Macerating standard; US: CSA Certified - ASME A112.3.4, CA: Macerating Standard CSA B45.9.
