As a typical American, I would have few, if any, opportunities to encounter or use a bidet. But as a world traveler and former resident of Europe, I have had ample encounters with them in private homes and hotels. I always thought them to be a very civilized way of cleaning up the nether regions after using the toilet, but the only ones I had seen were either separate large fixtures next to the toilet or expensive ones integrated into the toilet.....my house does not have room in the bathrooms for the former, and I am too cheap to fork out for the latter. So the notion of having a bidet at home remained a vague and unfulfilled notion.Then I ran across the line of affordable and well-reviewed bidet attachments produced by Luxe Bidet, and decided that the "Neo 320" model was the one to get, since it is the only model having dual nozzles AND the ability to use hot water to achieve a warm wash. Luxe Bidet does make a similar model (Neo 250) with warm wash but only one nozzle, and two other models (Neo 180 & Neo 185) with two nozzles but only a cold water wash. The second nozzle produces a water stream more suitable for the needs of women, so if you are a male-only household you could maybe choose to select the model with a hot water connection but only a single nozzle. And the hot water connection that allows a warm water wash is of course best for comfort, especially if you have the need or desire to use the bidet for longer periods; that being said, the wash temperature from a typical cold water only bidet is really not too uncomfortable for quick utilitarian washes.The Neo 320 consists of a large plastic assembly that includes a control console that sticks out to the right of the toilet seat, a flat section that gets sandwiched between the top of the toilet bowl and the hinge for the toilet seat & lid, and the nozzle section that sticks down at the rear of the rim of the toilet bowl. Mounting this is easy, since it only involves removing two screws from your toilet (the two that hold the hinge to the ceramic bowl), placing the bidet assembly between the hinge and bowl, then reinserting the two screws. This is done using only a screwdriver, assuming your toilet uses the plastic wing nuts on the screws. The bidet assembly has two large rotating slotted disks, and by turning these to the correct positions the two screws can pass through the slots in the disks with the necessary distance between them, and with the nozzle section positioned correctly in front of the bowl rim. Pretty much any standard toilet with separate bowl and tank would be compatible with this bidet. My only criticism of all this is that the added thickness of the bidet assembly between hinge and bowl will raise the rear of the toilet seat by about 1/4", and this means that the rubber bumpers under the rear of your toilet seat will no longer rest on the top of the toilet bowl. Luxe Bidet sells add-on bumpers, but I think they should include these as part of the kit and not treat them as an accessory.The connection of the two water lines from the bidet to your water service is also fairly quick and easy in most situations where the existing plumbing in the bathroom is not too ancient. The bidet comes with a plastic T-adapter for tapping the cold water supply that feeds your toilet tank. The procedure is to turn the cold water supply shut-off valve below the toilet until it is fully closed, then place a bowl or pan or folded towel below the toilet tank, unscrew the cold water hose from the bottom of the toilet tank, screw the T-adapter to the bottom of the tank where the water hose was formerly connected, then connect the cold water hose to the bottom of the T-adapter. This is all done using just your fingers and a plastic wrench that comes with the bidet; no other tools are required. Finally, the bidet comes with a short length of water hose, complete with a braided stainless steel cover, to connect the side port on the T-adapter to the cold water inlet on the back of the bidet's control console; the included plastic wrench is used for these connections. Turn the shut-off valve back on, and verify that there are no leaks. You can stop here if you have no immediate plans to connect the hot water supply, and the bidet comes with a cap to cover its hot water port if you are not using it. Connection of the cold water should take less than 15 minutes, or much less time if you have everything handy and don't get distracted or run into complications.Connection of the hot water line to the bidet is basically the same as with the cold water feed, except it takes longer because the only accessible hot water feed in the bathroom is usually the one under the sink, which is hopefully next to the toilet, but in most cases less accessible that working under the toilet tank. If your bathroom is set up with the toilet and sink NOT adjacent, then you will have problems; the bidet does come with a fairly long hot water hose, allowing the toilet and sink to be separated by a few feet, but if they are far apart or on opposite sides of the room, you will probably need to do something more elaborate than what Luxe Bidet planned for in their design. Anyway, assuming good toilet & sink positions, you shut off the hot water feed under the sink, remove the short hose that goes up from the hot water shut-off valve to the faucet, and insert the included metal T-adapter between the shut-off valve and the existing sink hot water hose. If your sink is built into a cabinet, then you will need to drill a small hole in that cabinet to pass the bidet's thin plastic (polyurethane) hot water line through. One end of the bidet's hot water line comes pre-terminated with a fitting that screws onto the hot water inlet on the back of the bidet's control console, then you run the hose to your sink, cut off any excess length with a knife or scissors, and the free end of the hose presses onto the barbed fitting on the side of the metal T-adapter under the sink; a screw-on collar secures the hose so it will not come off of the adapter. Again, all these connections can be made using the plastic wrenches that come with the bidet; no other tools are required except for whatever you use to shorten the hose. Turn the hot water shut-off valve back on and check for leaks.Here is where I encountered my only difficulty. The included metal T-adapter for the hot water connection has a rubber washer inside that is supposed to mate up with the threaded fitting on the hot water shut-off valve, but on mine that washer kept shifting out of position or flipping up on its side when the screwed the adapter into the shut-off valve, and water would leak from this point. I took the T-adapter to the hardware store in hopes of finding some fitting that would improve this deficiency, but nothing they had would help. The plumbing 'expert' there thought that the rubber washer was not actually required given the style of shut-off valve fitting that I had, and he advised just using lots of Teflon tape on the threads where the T-adapter screws onto the shut-off valve, and after I did that there were no leaks. But I sent an email to Luxe Bidet technical support (have not yet heard back from them) asking if they have a better suggestion.So, about the bidet itself......There are two important parts, the nozzles and the control console. The two nozzles are spring loaded pop-up types, much like what you see with underground landscape sprinkler systems that are normally recessed but pop up when the water is turned on. On the bidet, the nozzles face downwards, so they 'pop-down' from their recessed hiding positions when they are needed. When recessed, the nozzles hide behind a hinged splash shield that is there to prevent anything entering the toilet bowl, be it from urination or defecation or other, from landing on the nozzles and fouling them in one way or another. You can open the hinged splash shield for inspection or cleaning, but normally it remains closed over the nozzles. There are two nozzles, and one is your 'everyday' general purpose bidet nozzle that is aimed right where the user's anus would be positioned, and the other is aimed a bit more forward and with a different pattern to the spray, for better use for feminine hygiene requirements.The control console has two knobs. The smaller rear knob has three positions for "Nozzle Cleaning", normal "Wash", and "Women". If you turn on the bidet while the knob is set to "Nozzle Cleaning", the nozzles do not extend and they simply have water running through them down into the toilet bowl. In the other two positions, one nozzle or the other will extend when you turn on the water and spray water at an angle upwards to the front. *****Note, if you have children or pets that might like to mess with the controls, they could quite possibly bump the control lever upwards while nobody is seated on the toilet, and thus the water stream will shoot out of the toilet and across the room, impacting that wall of whatever is in front of the toilet. Obviously this makes a mess, and if left on for an extended duration, could result in serious water damage to that area of your house. Luxe Bidet sells an accessory T-adapter to use in place of the plastic T-adapter under your toilet tank, and this metal adapter includes a shut-off knob that will prevent the cold water from spraying when it is turned to the OFF position. I see two problems with this 'solution'; first, that accessory T-adapter is only available for the cold water feed but not for the hot water feed, so you could still have the same calamity with hot water spraying out unchecked, and second, who wants to find that after they have dome their duty on the toilet that the water will not spray because you forgot to turn the water on under the toilet? My recommendation is that you avoid this product if your bathroom is open to children of a certain age or some kinds of pets.The larger front knob on the control console is actually more lever-shaped, and it functions just like a sink faucet control that can rotate and tilt, for controlling water temperature and flow respectively. If you have a water system that takes a long time for the hot water to start flowing from the sink, you can turn the selector knob to "Nozzle Cleaning" and then turn the lever to the warm position to get the hot water flowing without actually using the bidet, then change the selector to 'Wash' or 'Women' to start using the bidet with warm water.I find that the controls are easy to use and intuitive. It is easy to dial in the desired temperature and flow rate (and thus how hard the water stream impacts your posterior). In normal use, just a few seconds is enough to clean up after defecation, but you can use it for as long as you want or need. Since, unlike the higher end integrated bidets, there is no warm air dryer with this Luxe Bidet model, you still need to take one wad of toilet paper, or something else that is suitably absorbent, to blot your hindquarters before getting up from the seat.The build quality of this bidet seems quite good, although it is obviously made entirely of plastic (Luxe Bidet claims that the actual water valves inside the control console are made from ceramic, and are replaceable). The control console is not entirely rigid on its plastic stalk that extends from under the toilet seat, but since the control console knobs move easily, this is not a problem.I wish that Luxe Bidet had done a better job of arranging things so that the two water lines coming into the rear of the control console would be less visible. I thought they could have a single hose (with dual tubes inside) snake down from the control console to behind the toilet and then connect the cold and hot water lines up down there, out of sight. But as it is, the two water lines are very conspicuous, and Luxe Bidet cleverly omits those from the photos of their product shown on their website and on the product packaging.I also found that the tiny roll of cheapo Teflon tape that came with the bidet was so flimsy as to be almost impossible to work with under the sink, and I ended up using some slightly heavier Teflon tape that I already had on hand.The installation instructions are thankfully in clear English with lots of illustrations, although the quality of those illustrations vary from almost childish to very professionally drawn.Some dimensions:- The Control Console measures approximately 6.5" x 3.5", and the its center line is about 9.5" from the center line of the toilet bowl. This should allow the Control Console to be far enough from the outside edge of any toilet bowl to avoid a collision.- Luxe Bidet specifies that the maximum distance from your toilet bowl center line to the outside edge of the toilet bowl is 7.75". This makes sense because if you add that 7.5" + half the 3.5" width of the Control Console, you will get the 9.5" distance that I mentioned above, and in the case of such a wide toilet bowl the edge of the Control Console and the outside edge of the toilet bowl will just be touching.- Luxe Bidet specifies that using this bidet's adjustable slotted disks, you can adjust for distances ranging from 3.5" to 8.25" between the centers of the two screws that hold the toilet seat hinge to the toilet bowl.- Luxe Bidet specifies that your toilet needs to have at least 1" from the center line of the two hinge screws to the front of the toilet tank.- Luxe Bidet specifies that using this bidet's adjustable slotted disks, you can adjust for distances ranging from 1.25" to 3.5" from the center line of the two hinge screws to the inside edge of the toilet bowl rim, where the two nozzles will protrude down into the bowl.According to Luxe Bidet, all of their bidets have integral check valves to prevent backflow.Each bidet has an ID number (like a serial number), which they say you must submit the ID to them via their website in order to activate the free extended warranty; the product has a standard 18 month limited warranty. The warranty slip says that the extended warranty is 2 years, but it is not clear whether that means the standard warranty gets extended TO 2 years, or BY 2 years, i.e. 24 months or 42 months.Finally, I thought that I would repeat a bit of wisdom often used by recent converts to bidet use, when confronted by disbelieving skeptics. One version goes, "Suppose you are a manly man and you have some mud or something on your driveway, would you just smear it around with a wad of paper, or would you get our your pressure washer and clean it properly?". The other version goes, "Suppose you have a baby and after changing its diaper you find some poop on your hand or forearm.....would you just wipe it quickly with paper until you can't actually see the remaining poop, or would you wash it off with water?"
