TOTO Vespin II 1G WASHLET+ S300e Two-Piece Toilet and Bidet System - 1.0 GPF

The TOTO Vespin II 1G WASHLET+ S300e toilet and bidet system marries style and function in one fantastic unit. The Vespin II 1G toilet features an efficient, 1.0 gallon flush that effectively sweeps through the bowl thanks to TOTO’s powerful tornado flush system. The toilet is also coated with TOTO’s ultra-smooth CeFiONtect glaze that deters residue from sticking, and the Vespin II 1G is a universal height toilet and ADA compliant, making it an accessible option for those with mobility limitations. It’s worth mentioning that TOTO designed the Vespin II 1G toilet and the S300e WASHLET+ to seamlessly fit together, with the toilet cleverly concealing the bidet seat’s cords and hoses. This design feature results in a supremely sleek silhouette, though do keep in mind that the S300e WASHLET+ included in this system is only compatible with TOTO WASHLET+ toilets. 

The TOTO S300e WASHLET+ comes packed with great features designed to skyrocket the quality and comfort of your toileting experience. The S300e comes with four wash modes (front, wide front, rear and soft rear) for comprehensive cleansing, and an instant water heater provides unlimited warm wash water no matter how often or long the unit is used. The water pressure, water temperature, wand position and seat temperature are all adjustable for optimum comfort, and oscillating and pulsating (massage) spray options soothe and relax tender areas. In addition, the S300e comes with a warm air dryer with adjustable temperature settings, allowing you to eliminate abrasive and costly toilet paper from your routine, and the automatic deodorizer eliminates unwanted odors for embarrassment free restroom trips. Two user presets enable you to program your favorite settings into the unit’s remote for a personalized, one-button wash, and the seat’s energy saving mode cuts down on electricity usage when the seat isn’t in use. Furthermore, the S300e takes unit hygiene to the next level by using sterile, electrolyzed water (EWATER+) to mist the bowl prior to use and to sanitize the bidet nozzles after each use. With its streamlined look and wide array of features, the TOTO Vespin II 1G S300e WASHLET+ toilet and bidet system is a great way to add style and luxury to your bathroom.

The TOTO Washlet+ comes with a 1 year full warranty for residential use, and a 1 year full warranty for units installed for commercial use.


We cover tax at the prices quoted, so no need to worry about a surprise tax fee added on during checkout, we've got you covered!


We also pay for shipping, so the price you see is the price you get!

TOTO Washlet+ units ship via freight, and ships on a pallet.  The shipper will call you when the unit is in your area and ready to be delivered. This allows you to schedule delivery, so you don't need to worry about it being delivered when you're not home.  Because toilet bowls are fragile, we recommend looking over the unit quickly when it arrives.  It's very rare for anything to be cracked, but it has happened.  We see about a 5% break rate, meaning about 1 in 20 have damage. When the unit arrives, look it over before signing for it. If anything is broken, don't sign for the package. Instead, take pictures and email them to or text them to 248-974-4030, and refuse delivery. This allows us to file a claim with the shipper and get another one out to you within 24 hours.


Because of the fragile nature of toilet bowls, returning one is a tricky process.  Should a return be required on your Washlet+ unit, TOTO requires that it be shipped back via freight, and shipped back on a pallet.  TOTO also charges a restocking fee of 30%, and will not cover shipping either way. TOTO also requires that the unit come back in 100% brand new condition. If the unit comes back in any condition other than 100% brand new, resellable condition, no refund of any sort will be issued.
