TOTO Aquia IV Washlet+ S7 Two-Piece 1.28 GPF & 0.9 GPF Compatibility

The TOTO Aquia IV Washlet+ S7 is a two-piece smart toilet with integrated bidet. Verify these five compatibility points before ordering.

  • Rough-in measurement: Requires 12-inch rough-in (distance from wall to drain center). 10-inch and 14-inch rough-ins are supported with the optional TSU01W adapter, sold separately.
  • Bowl shape: Elongated bowl only. This model is not available in round.
  • Floor clearance: Ensure at least 21 inches of clear space in front of the bowl rim for comfortable use.
  • Water supply location: Your water supply shutoff should be accessible. The toilet connects via standard ½-inch supply line.
  • GFCI 120V outlet: A GFCI-protected outlet must be within 3 feet of the toilet to power the integrated bidet seat and controls.

For reference: Measure from the wall behind the toilet to the center of the floor drain; measure the distance from the bowl centerline to each side wall to confirm adequate floor clearance.

Installation steps

  1. Turn off the water supply to your existing toilet and flush to empty the tank.
  2. Remove the old toilet by unbolting the base, then disconnect and cap the water supply line.
  3. Clean the floor and check that the flange (drain opening) is in good condition; replace if cracked.
  4. Place the new wax ring on the flange, then lower the Aquia IV onto the bolts and secure with washers and nuts hand-tight, then snug with a wrench.
  5. Connect the water supply line to the fill valve inlet and turn the shutoff valve back on to check for leaks.
  6. Locate a GFCI outlet within 3 feet of the toilet and plug in the power cord for the integrated S7 Washlet+.
