Bidet toilets & add-on heated, personal-cleaning toilet seats

At left we include an illustration of the Japanese bidet toilet ([4]. photo - Wikipedia[5]). photographed in the Asahikawa grand hotel in Asahikawa, Japan. Bidet toilets deliver a warm water washing oscillating stream from beneath the seat (shown) that is adjustable in temperature and water spray volume.

The toilets generally include a heated seat with a temperature control, warm air drying, and in some models massage and deodorizing features.

In normal operation the toilet won't send its oscillating spray into the air as the Wikipedia photographer achieved for this photo; the Toto bidet toilet seat includes a pressure sensor to prevent such accidents.

The Toto Washlet® toilet or similar bidet toilets are reported to be installed in 72% of Japanese households - a figure which we question considering the cost. Contact information for Toto is below in this article. This is a dual flush water-saving toilet.[4][5]

The Toto B100 Washlet™® toilet seat [Image] is a retrofit heated and bidet-type washing mechanism that can be retrofitted to Toto (and possibly other) elongated bowl toilets. Particularly for the disabled, models of Toto's bidet toilets or toilet seats can be a significant benefit, as was the model installed by the author's sister.

Also as an aid to the elderly or disabled are electric raised-seat toilets [Image] that provide a lift mechanism to assist the user in getting on and off of the toilet.

Toto's Washlet® ($1,350. USD) is an add-on toilet seat that is plugged into a nearby electrical outlet and connected to a water supply to provide heated water, a built-in deodorizing system, a heated toilet seat, a warm air dryer and other features.

A self-cleaning spray wand washes the user's bottom.

The seat pre-mists the toilet bowl prior to use to improve clean flushing and 25 seconds after the user flushes the toilet the Washlet® sprays the toilet bowl with electrolyzed water that the company brands as eWater+ using a process that temporarily changes the property of water to include properties similar to household bleach NaOCL or sodium hypochlorite to improve tilet bowl cleaning.

Prices for Toto's back flush or bottom flush toilets range from about $1,700 to $4,000 for the company's Neorest700H#01 dual flush toilet with an integrated Washlet seat and ewater+ while prices for Toto add-on toilet seats that can be mounted on an existing toilet range from about $250. to $1,700. USD.

Contemporary gravity-flush toilets use a tank attached to the toilet bowl itself, relying on improved flush valve controls to provide the water flow rate into the bowl to empty it and clean the bowl sides. We illustrate several types below.
