Gather Your Tools and Prep the Area

Your new Infinity Eaze z3 includes all of the parts required for installation, but before you begin you will want to have a few extra tools on hand:

  • Adjustable Wrench
  • Phillips-head screwdriver 
  • Flat-head screwdriver
  • Towel (for catching extra water drips)

Step 1: Prepare the Water Supply

Before installing your Infinity Eaze Z3 bidet seat, you’ll first need to prepare the toilet’s water connection.

  1. Turn off the water supply valve behind the toilet.
  2. Flush the toilet to empty the tank.
  3. Hold the flush lever down for a few seconds to release any remaining pressure in the line.
  4. Disconnect the existing water supply hose from the bottom of the toilet tank.
  5. Attach the included T-valve to the toilet tank fill valve.
  6. Hand-tighten only to avoid crushing the rubber washer.

Pro Tip: If your current water supply line is too long or rigid you can replace it with a shorter, flexible braided steel supply line from your local hardware or plumbing supply store.

Step 2: Remove Your Existing Toilet Seat

  1. Locate the mounting bolts at the back of your current seat. Determine if your setup has nuts on the underside of the bolts that need to be removed or if they unscrew from the top.
  2. After removing the old seat, clean the area thoroughly to ensure a secure, level fit for your new bidet seat.

Step 3: Install the Mounting Plate

  1. Position the Infinity Eaze mounting bracket over your toilet’s bolt holes. The rounded side of the bracket should be facing your toilet tank.
  2. Insert the provided bolts through the bracket and toilet.
  3. On the bottom side of the bolt, attach the rubber cone washer and the retaining clip.
  4. Install the nut and loosely tighten. At this stage, keep it slightly adjustable. You’ll align everything perfectly before fully tightening.

Pro Tip: If you are installing your bidet seat on top of a riser, you will need longer 6” bolts, which can be found here.

Step 4: Attaching the Bidet Seat

  1. Set the bidet seat on top of your toilet and line up the grooves on the underside of the seat with the mounting bracket.
  2. Once you have it lined up, you can slide the seat back firmly on it. The seat should click and lock into place if successful.
  3. Give a gentle pull from the front to make sure everything is locked into place.

If adjustment is needed:

  • Loosen the mounting nuts underneath the toilet.
  • Slide the seat forward or backward as needed.
  • Re-tighten once properly aligned with the bowl.

Pro Tip: If you need to remove the bidet from the mounting bracket after you have locked it into place, grab the lower housing and rotate up slightly and then wiggle forward and remove.

Step 5: Connecting the Water and Power

  1. Attach the elbow side of the included bidet hose to your bidet seat. Be careful to avoid any cross threading and hand-tighten only.
  2. Connect the opposite side of the hose to the T-valve, making sure the rubber washer is inserted.
  3. After ensuring that all water connections are secure, slowly turn back on the water supply. Check for leaks as the toilet tank begins to fill.
  4. Plug in the electrical cord and wait for the unit to power on.

Step 6: Set up Remote and Test Bidet

  1. Install the two AA batteries into the remote control to get started.
  2. In order to test the features of the seat without being seated on it, you will need to activate the skin sensor on the right-hand side of the seat when facing it. You can do this by placing a hand or arm over this portion of the seat to begin.
  3. Find an easy-to-reach location for your remote control. The bracket can be mounted on the wall with either the adhesive strips on the back or the included screws.

Step 7: Enjoy!
