Under seat USABidet

Under seat USABidet sm underseatMade from solid chromed brass and medical grade stainless steel, these bidets are designed and manufactured in America to be a durable alternative to expensive electronic toilet seat bidets. The obvious advantages under seat type bidets have over the traditional European style bidet, is that you don’t have to move from toilet to bidet to clean. Also cheaper because they don’t take up floor space and do not require major plumbing alterations to install.

A correctly integrated USABidet cleans very efficiently and does not require any learning to use – if you can sit on a toilet, you can use one of these! A cost-effective solution for people who have restricted ranges of body movement (such as is common with the elderly or obese); they are ideal for anybody who finds more conventional cleaning methods unsatisfactory, difficult or impossible. Because the water stream angle is able to be adjusted easily during use, these bidets offer an enema effect which is superior to many electronic bidet seats costing 3 times as much. This function becomes invaluable for individuals who suffer from constipation, hemorrhoids, irritable bowl syndrome or many other similar ongoing medical conditions; enabling effective irrigation of the last few centimeters of the colon. Moving your body slightly rearwards will also allow efficient hands-free cleansing of the vaginal area in women.

With no complicated electronic circuitry to malfunction, water stream strength is easily controlled with your right hand via normal tap (or with the latest models a durable 1/4 turn ceramic seat valve) – not some hard-to-see button. The typical control panels on electronic bidet seats are often both in the road & difficult to operate for an obese or handicapped person. Not so the controls for the USABidet – this bidet was designed by big-bum Americans, not some tiny-ass Korean or Japanese.

A useful characteristic of USABidets is that the bidet wand stays with the seat when raised; leaving a bare pan. This unique feature makes cleaning of the pan itself very easy compared to all other types of under-seat bidets currently available. The bidet wand itself is self-retracting and hides out of site under the seat when not in use.

This Bidet is available with the option of a pressure limiting valve; for people who wish to use this bidet in conjunction with a hand held model, or (for safety reasons) where the water pressure is very high (in excess of 500kPa). Very little mechanical knowledge is required as these parts come already sealed and pre-assembled. Supplied with easy to follow, step-by-step installation instructions with clear explanatory photos, all our products come with the complete assurance of a full 12 month warranty on all materials and manufacture.

Please be aware that these bidet kits are intended to be installed by the home owner themselves and may not be compliant with local regulations in the particular area or country you live. Plumbers installing this product within Australia will normally be required to ensure water supply is protected by an RPZ valve (usually after the water meter). An exception to this rather costly requirement is when the water supply to the bidet or toilet is only from rain water tanks. To avoid misuse; we therefore recommend under-seat bidets be not installed where the likelihood for irresponsible use may exist. Please see our Bidet Choice page for more details.

At full blast this bidet provides an absolutely massive stream of water – and consequently; a very effective enema function. At gentler pressures it does effect reasonable peripheral cleaning; but similar to many Electronic Bidets – doesn’t do such a good job of cleaning around the anal area (the Toto Eco Washer is the best bidet seat we have tested in this respect).

For folks who want the convenience of both; we supply an adaptor that lets you use the USAbidet in conjunction with a hand held model. This is definitely the best  option for external cleaning effectiveness, and besides being handy for cleaning the toilet bowl, this additional option gets the ladies needs perfectly catered for as well. Please remember though; hand held bidets must have water supply pressure limited to under 350kPa. This normally means you will need to buy your USABidet Kit with the pressure limiting Tee Assembly option when using it in conjunction with a hand-held bidet.

For colder climates; the USABidet can also be used in conjunction with the Rezi Water Heater – found under Bidet Accessories. For these additional options, please see the configuration photos provided with the Complete Seat Kit details.

 Everything needed is supplied; installation usually takes less than 20 minutes (once the bidet has been attached to the seat). The only tools then usually required are two 10” shifting spanners and a pair of multi-grip pliers. Your existing pipe from the wall tap to the cistern tank is simply replaced with the complete Tee assembly shown.

For those who don’t understand the benefits of enema function as provided by the USABidet; this user review from PoopReport – if somewhat indelicate – pretty much explains it all:

“Another issue I discovered: the direct stream from the bidet can be used as a makeshift enema. This blew my mind. If you’ve ever experienced a stool so dry and hard it almost rips your o-ring coming out or even gets stuck halfway, you would give a hundred dollars for one good burst from this bidet. When I get on the throne in the morning, I give myself a good shot before I defecate, thus lubing the pipes. Then even the largest, driest, most difficult logjam slips easily out. After a normal movement, even when I think I’m clean, I relax the sphincter and give myself a squirt right up the middle and into the lower part of the colon. One would scarcely believe the stuff that’s left in one’s colon after defecation. Usually several more substantial chunks of fudge come out — chunks which would otherwise have been there festering until the next movement.”

Interstate customers please note: We use Australia Post as our freight provider mainly for reasons of convenience and reliability. Whilst freight costs for small items (like hand-held bidet kits) is pretty much on a par with other couriers, Australia Post charges for bulky items like these USABidet complete seat kits (irrespective of weight) is pretty steep – especially when interstate.
