What Sets the TOTO Soirée Apart From TOTO's Other One-Piece Toilets
What sets the Soirée apart is decorative, architectural styling: a fully skirted one-piece body with crisp geometric edge lines and a tailored tank profile, rather than the smooth minimalist curve most skirted one-pieces use. Underneath the styling it is a 1.28 GPF elongated bowl at Universal Height, so the seat sits at chair height instead of the lower standard height.
Flushing is TOTO's TORNADO FLUSH system, which sends water through two nozzles to create a centrifugal, cyclonic rinse around the bowl. The ceramic is finished with CEFIONTECT glaze, an ultra-smooth coating that gives waste and mineral scale less to cling to. Both are standard across the Soirée line, including the WASHLET+ sets here and the rest of TOTO's WASHLET+ toilet sets.
Smaller details separate it from close siblings such as the Guinevere series, which shares the same 1.28 GPF Tornado flushing and the same WASHLET+ tiers but a softer, sculpted profile rather than the Soirée's hard edges. The Soirée trip lever can be specified in Polished Nickel, Polished Brass or Brushed Nickel, an option TOTO lists on the standalone Soirée one-piece rather than on the WASHLET+ sets.

If you are cross-referencing an older Soirée
An older Soirée is not the same toilet as the one sold today. TOTO's specification sheet for the discontinued MS964214CF(G) Soirée one-piece lists 1.6 GPF, the Double Cyclone flushing system and SanaGloss glaze. The current Soirée one-piece, MS964124CEFG, is 1.28 GPF with TORNADO FLUSH and CEFIONTECT instead. On the WASHLET+ sets the toilet is listed as a separate component, CST964CEFG, which is the number to work from when matching parts to the fixture rather than to the seat. If the water use is what you are weighing, the guide to 1.28 versus 1.6 GPF covers what changes.
Soirée WASHLET+ S2 vs. S5: Which Set to Choose
The practical difference between the Soirée WASHLET+ S2 and the WASHLET+ S5 is how you control the seat. The S2 uses an arm-mounted panel attached to the side of the seat; the S5 uses a wireless remote control. Almost everything else you touch day to day is shared between them.
Both sets include front and rear warm water cleansing with adjustable temperature and pressure, a warm air dryer with variable temperature, a heated seat with its own temperature control, and a deodorizer. Both also carry PREMIST, which wets the bowl surface before use to aid in the removal of waste, and EWATER+, which electrolyzes water into hypochlorous acid to keep the wand and bowl hygienic. Neither one heats water in a holding tank, so warm water arrives on demand rather than running out mid-wash. Where the S5 goes further is personalization: TOTO lists stored settings for up to four users. Pick the S2 if you would rather have a physical panel permanently within reach; pick the S5 if more than one person wants their own wash settings, or if you prefer a seat with no side panel breaking the line. Every toilet on the store paired with each seat is grouped in WASHLET S2 toilet sets and WASHLET S5 toilet sets.
Will a Soirée Fit Your Bathroom?
A Soirée fits a standard 12-inch rough-in as supplied, and TOTO offers 10-inch and 14-inch rough-ins for the series using an adapter sold separately. Measure before you order. Rough-in is the distance from the finished wall to the center of the closet bolts at the base of your current toilet, taken to the wall rather than the baseboard. If your figure lands within half an inch of 10, 12 or 14, that is your size, and the toilet rough-in size guide walks through the measurement and lists which TOTO series offer which sizes.
Two more checks. The Soirée bowl is elongated only, so there is no round version for a tight powder room where the door swing is already close. And the Soirée is Universal Height throughout the range, marked by the F in a model number like MW9643446CEFG, which places the seat roughly 17 to 19 inches from the floor, about two inches above standard height. That is the ADA seat range and suits most adults, though it can sit high for small children; the trade-off is set out in the comparison of Universal Height and standard height. Last, plan for power: every WASHLET is an electric seat, so both Soirée sets need a grounded outlet within reach of the toilet. Adding one is an electrician's job rather than a plumber's, and it is easier to settle before the fixture arrives.
