A common complaint with a lot of modern technology is that it is often too complicated for the average person to be able to use easily – let alone understand how it works. This also true of most Electronic Bidet Toilet Seats; where you must carefully study the instruction manual before use – or risk some rather surprising or unexpected behaviour from an otherwise docile looking appliance. The flip-side to this coin is that when something does go wrong (as it eventually will), you can’t simply call an electrician or a plumber to get it fixed. A fully featured Electronic Bidet toilet seat, is by necessity a complex and sophisticated electrical appliance; a fact typically also reflected in the price.
We have discovered that many people are put off from buying an electronic bidet toilet seat for these exact same 2 reasons: cost & complexity. This simple yet elegant electronic bidet seat, does – we believe – strike the perfect balance between: performance and features, versus: cost and complexity. Displaying those reassuring words “Made in Japan”, this bidet seat certainly lives up to expectations of Japanese quality and ingenuity. The parent company Aisin-Seiki, although more synonymous with precision equipment like carburetors and automatic transmissions in motor vehicles, is certainly not backward in their approach to modern electronic bidet seat design.
Providing just warm water washing and a heated seat, we have found that these 2 features are actually the most requested by 90% of average users. The washing wand is extended by water pressure, and the washing angle can be changed by sliding the operating lever forward or back as required. These simple, hydrualic and manually operated functions mean considerably less complexity, as well being far less likely to cause any trouble down the track.
Although the bidet nozzle is washed reasonably well on its return, contamination is also minimized by using a steeper than usual delivery angle of 62 degrees. The nozzle tip of the bidet wand is detachable, and the whole bidet seat can be quickly removed for easy cleaning by pushing one button and simply sliding the whole seat forward. The lid can also be individually removed for cleaning (although I am not sure why that would ever be necessary) and both the seat and lid sport a soft close feature (great for kids). Overall size of this bidet seat is very compact compared with most other electronic models seen today. Also good for the average Aussie: there are no control panels at the side of this seat to get in the way of larger behinds.
We now also supply a non-electric version of this Bidet Seat; for folks who don’t need warm water or the warm seat, but still want the other unique features provided by this high quality Japanese appliance. External dimensions are similar, and the non-electric version – apart from the seat being slightly shorter – looks exactly the same, just without the temperature control panel and electric supply cord. Plumbers installing this product should note that the Aisin Non electric version does not include a vacuum breaker device – as found on this Electronic model and the Toto Eco Washer. Where full compliance with backflow regulations is required; we suggest choosing these alternate models.
The operating lever is positioned within easy reach of your right hand. The 1/4 turn, ceramic-seat valve is operated by turning the lever down slightly to start washing, then turning progressively further to increase washing pressure. A spring assists in returning to the off position. We found that the initial washing position was just about perfect for anal washing, but sliding the control lever further forward will be required for frontal washing (bidet or feminine function).
The electronic control panel is also found on the right side of the seat and has just 2 buttons; one to control water temperature: high/low/off, and another for seat temperature: high/low/off. The current selection is indicated by small orange LEDs. Although it is possible to adjust these while sitting on the seat, they will normally be set as required and then simply left at this setting. In the non-electric version, this panel is simply blanked off.
Despite being obviously made to suit the slightly elongated toilet pans common in Japan; we found that this bidet seat does fit Aussie toilets surprisingly well, with the front bumper rubbers making almost full-width contact with the top of the pan. The seat bracket will however usually need to be positioned in the rearward-most position for most Australian toilet pans.
The most surprising feature of this bidet seat is that in can deliver a very effective enema function, while at the same time being able to achieve quite good posterior and feminine (bidet) washing – all from the same nozzle. Clever little devils those Japanese! This all-around usefulness is due to the unique approach taken by Aisin of having 4 delivery jets in the nozzle. Two relatively large holes, centrally located forward and rear; deliver parallel streams of water exactly 5mm apart. With washing intensity able to be varied accurately by the operating lever; at full flow these twin jets combine to provide an exceptional enema function, while at the same time making body position slightly less critical than is normally required for most other bidets with a single jet. Two smaller diameter jets (3mm apart ) on either side of the central main jets, complement the two main jets by cleaning at the sides, and also help to introduce some air (between all four jets) so that what enters your rectum is a mass of aerated water that is at the same time both concentrated and penetrating (similar to Izen’s patented ‘vortex spinning water stream’ nozzle). When a reduced flow rate is selected, all four jets function individually to deliver a soft spray that is quite effective for standard posterior or feminine cleaning.
Back-flow prevention is well taken care of by a foolproof vacuum breaker device. Regardless that this device is out of sight under the rear cover, measurements are nevertheless well within Australian Standards (outlet distance above the rim of the toilet pan). The NC-200W-AS non electric version of this bidet seat does not have this vacuum breaker device; backflow prevention in this model being taken care of by the non-return valve in the isolating tap outlet only.
One notable advantage these bidet seats do have over most other electronic bidets out there: if the power goes off they will wash just the same – only without warm water (or the warm seat). In fact we do keep ours switched off for most of the year – only using the warm water/warm seat functions during the winter months.
Everything needed is supplied in the kit and installation usually takes less than 20 minutes. The only tools normally required are a Phillips-head screwdriver, a 10” shifting spanner and a pair of multi-grip pliers. Your existing pipe from the wall tap to the cistern tank is simply replaced with the complete assembly shown.
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; this product comes with the complete assurance of a full 12 month warranty on all materials and manufacture.
Although you can access the official Aisin Brochure left (PDF); overall dimensions listed in this brochure are a bit misleading. This bidet seat will normally fit standard Australian toilet pans (W340-360mm x L420-460mm) just fine. Please see the individual product page for more accurate details.
