What the Infinity Eaze Z3 Is
The Infinity Eaze Z3 is an electric bidet toilet seat that mounts to the same two bolt holes your current seat uses and washes you with warm water drawn from the toilet's existing supply line. Infinity sells it as the upgraded replacement for the Cascade 3000, and it is the only Infinity seat this store carries.
Warm water that starts warm and does not run out
The Eaze Z3 heats water as it flows instead of storing it in a tank, so the wash is warm from the first second and stays warm for as long as you hold the button. There is no reheat wait between two people using it back to back. Every seat on the store built this way is grouped under instant and unlimited warm water.
A stainless steel nozzle that cleans itself
The nozzle is stainless steel and offers a front and a rear wash. It moves back and forth during the wash for fuller coverage, the spray is aerated rather than a hard jet, and Silver Nano filtration helps keep the wash water clean. The nozzle sanitizes itself after every use. If this is your first bidet seat, how bidets work covers the mechanics.
Heated seat, warm air dryer, deodorizer
The seat warms to a temperature you set, the warm air dryer has its own adjustable temperature, and a built-in deodorizer handles the air in the room. One-touch wash and dry runs the whole sequence without you stepping through it button by button. To see how that compares with the rest of the store, browse bidets with a dryer.
The details you notice daily
The lid is sittable and supports up to 300 lbs. A seat sensor keeps the wash from running unless someone is on the seat. Power-saving mode cuts standby draw, and the quick-release mount lifts the seat off for cleaning.
What the Infinity Eaze Z3 Will Not Do
The downside of a bidet seat like the Eaze Z3 is that it depends on power and on your toilet's geometry, and it leaves the fixture exactly as it was. The limits are worth knowing before you order:
- It will not run without electricity. There is no non-electric version, and it needs a GFCI outlet within 3 feet of the toilet.
- It will not change your bowl's shape. You order round or elongated to match the bowl you already have.
- It will not fit a toilet whose seat-bolt holes sit outside the 5.5 to 7.5 inch range, or one with less than 1.5 inches between those holes and the front of the tank.
- It will not look like a plain seat. The housing that holds the heater, pump, dryer, and deodorizer sits at the back, so it stands taller there than the seat you are removing.
- It will not replace the toilet. If you want the wash built into the fixture instead of the seat, start with complete bidet toilets.
Fit and Installation for the Infinity Eaze Z3 Bidet Seat
The Eaze Z3 mounts using a standard bottom-mount setup (a top-mount kit is also available) and adjusts to mounting-hole spacing from about 5.5 to 7.5 inches, with a minimum tank clearance of 1.5 inches — measure your toilet against those numbers before ordering.
It fits both one-piece and two-piece toilets and is compatible with many French-curve toilets, including a confirmed fit on the Kohler Santa Rosa K3811, though that compatibility isn't guaranteed across every French-curve bowl.
It's also built with accessibility and aging-in-place use in mind, with a remote control so seat functions don't require reaching or bending.
