Easy-Clean Glaze

The CEFIONTECT glaze creates an extraordinarily smooth ceramic surface that helps keep the bowl clean. By preventing debris and mold from adhering to the porcelain, it ensures that routine bathroom maintenance requires less time and effort. A common feature in Toto One Piece Toilets.

Smooth Trapway Design

The internal trapway is fully glazed to match the smooth texture of the bowl, allowing waste to flow smoothly without catching on rough ceramic areas. This internal design works in harmony with the flush engine to maximize performance.

TOTO Ultramax One-Piece Compatibility

The TOTO Ultramax is an elongated front one-piece toilet. Confirm these four things before ordering.

  • Rough-in measurement: Standard 12-inch rough-in configuration.
  • Floor space: Elongated bowl requires about 18½ inches from the wall to the front of the bowl for maximum seating comfort. Confirm at least 15 inches of side clearance from the bowl centerline.
  • Water supply location: Your incoming water line should connect to the left or right side of the base. Standard ½-inch shutoff valves work with this toilet.
  • Drain configuration: This toilet has a floor drain only. Wall drains are not compatible; the drain must exit the floor at your 12-inch rough-in point.

For reference: One-piece toilets are heavier than two-piece models (approximately 75 lbs); plan for two people during installation.

Installation steps

  1. Turn off the water supply and flush the existing toilet to empty the tank and bowl.
  2. Disconnect the water supply line and remove the old toilet by unbolting it from the floor.
  3. Clean the floor around the drain opening and remove the old wax ring or seal.
  4. Install a new wax ring (or rubber seal) on the floor drain opening, centered on the drain.
  5. Lower the new toilet onto the wax ring, aligning the bolts with the floor holes, and tighten bolts hand-tight then with a wrench.
  6. Reconnect the water supply line, turn on the water, and fill the tank to test for leaks around the base and connection points.
  7. Install the included SoftClose seat onto the bowl mounting holes and adjust as needed.
