I first bought a complete detachable bidet toilet seat with 2 spray nozzles built in (one for anus, plus one for female). But the seat was odd shaped, with a smallish hole and the seat should have been a bit larger for our (approx 2000 model year) Kohler Elongated toilet with plastic seat, it didn't sit on the front rim well. Also the water pressure spray was a bit low although the instructions said there was an internal valve to increase pressure. I didn't see needing to detach it for cleaning under it. Anyway, I was not sold on it and returned it. I then read a lot more reviews and decided to get this greenco bidet attachment that fits between the seat and the toilet. I love that it has one simple, instead of two nozzles. It only has one nozzle but with the angle adjustment that swings the whole nozzle arm back or forth. Since the nozzle is hinged, it seems less likely to break from an impact like other's I've read about as well. I liked it so much, I installed one on my other toilet. The nozzle retracts when off and self cleans as it's turned on and has Plenty of pressure, full blast is not needed and it has 4 water stream holes spraying. Now because these bidet attachment type units are sandwiched under the toilet seat bolts, the toilet seats don't lay totally flat in the back, their back built in bumps no longer touch the toilet rim, till when sat on they flex. This seems to be the only draw back of these bidet attachments compared to a complete bidet seat. But these are so much cheaper and simpler and seem more reliable. I may buy some universal self stick toilet seat bumpers to put in the back. I see some units come with some. I live in Colorado and it is winter now and I was concerned that the water spray would be too cold. But I and my male housemates are pleased with the water temperature. The water is warmed to room temperature since it's in the lines before coming out. So it seems for most people, the expensive heated water bidets may be overkill. Our toilet paper usage has dropped significantly, just one drying wipe is all needed afterwards. So this is going to pay for itself in no time and help save our environment and keep us cleaner than ever. I think it's a must have for everyone. A few problems I saw in reviews: This does come with a clear heavy vinyl tubing for the water feed line to the attachment. It requires you to heat the stiff tube ends when attaching each, so that they will press slide all the way onto the sealing pipe nipple. This was simple for me, I just used the flame of a lighter held briefly about 2 inches under the tube end as I rotated the tube end, heating it from the inside and outside, but Not letting the flame touch the tube at all. Don't forget this step that is in the instructions otherwise the end might not press all the way onto the nipple, then the tube might pop off and leak. Don't forget to slide the nut over the tube end before sliding onto the nipple. Another problem some buyers had is the hardware package comes with a clear solid washer that must be installed into the suppled nylon T water adapter so it will seal when screwed onto the bottom large threaded nipple of the toilet tank. Some buyers overlooked or lost this washer that is in the directions and then complained the T adapter leaked upon turning on and then tried to fix the leak by applying teflon tape which will never replace a missing washer.. The hardware seems of good quality. The T water adapter is a solid nylon that attaches under the toilet tank. Don't over tighten any of the connections, they could break if over tightened with pliers I'm sure. I used my hands and didn't use all my force at all, just to snug. Never had to use pliers as all the attachment ends have wings for finger tightening. Nothing has leaked at all. I did check for leaks days after installation and asked my housemates to watch as well, no leaks. I am concerned that now there are more connections that could potentially leak and flood my bathrooms and I will be wise and check connections from time to time. I believe this greenco is not prone to leaks compared to some of the other bidet offerings. I also don't turn the water supply knobs all the way to full behind the toilet. Because it's always wise to only turn on enough to feed the toilet a reasonable supply of what it needs to fill and not more, in case there is ever a major leak so the flooding won't be as bad and also so that when someone flushes a toilet and someone is using the shower, the water pressure drop won't be as bad for the person in the shower. As always, it's very wise to shut off our home water supply main when we go on a prolonged trip. My parent's hardly ever went on a trip but one time they did and their old basement toilet tank cracked on it's own and slowly flooded their bathroom, causing some damage.. It seems to me that these bidets controls should have some spring action so that they return to the off position when turned on. So that if accidentally turned on, like by a kid playing with it, it'll turn back off. Because if left on, even with the lid closed, some water comes out between the lid front. But I didn't see any made this way. Yes this one is made with lots of plastic like most. I looked for a brand, made with solid metal and only saw one and it was expensive but the metal was cheap and rusted bad quickly and leaked the reviews reported. Ok I tried to give you all the best advice and info I have, I hope you consider a bidet, we are happy with our purchase.

Easy to install, but some creative tweaking may be necessary to do the job correctly

OK, I just received this today. However, this particular Greenco bidet is one that I have been using for years. Every time I switch apartments, I order a new one. (for the money you pay, it is easier to leave the old one behind) So I'm very experienced at both using and installing this particular model of bidet. And it's pretty nice (especially for the price!) But it's not perfect In use...Well, as many others will say...once you get used to using a bidet, you will HATE toilet paper and wonder why it took you so long to start using bidets? It's like taking a shower every time you use the toilet. At least for your butt get extremely clean.....literally FRESHLY SHOWERED CLEAN. I'm not going to write too much about using the bidet except to remark (again) that I have been using this specific model of Greenco bidet for years. So I must like it, obviously. I keep coming back to this model as it is one of the only readily available (and inexpensive) mechanical bidets with an ADJUSTABLE nozzle for up/down spray. That makes it so easy to get the whole area clean quickly, without having to adjust your BUTT on the toilet seat. Make the machine do the work, in other words... Now, on installation...even people who do video installations and do it CORRECTLY are often missing a step or two, which I have learned from experience. Again, I've installed this model several times. I know the tricks to not just get it done, but get it done RIGHT. There are two issues you need to be aware of. 1) The sliding brackets that hold the bidet attachment to the toilet are the wrong size for your toilet, and they are not adjustable. I believe this bidet attachment was designed many years ago, when all the toilets used metal screws to attach the toilet seats. These days, 99.99% of the bolts that hold toilet seats to toilets are PLASTIC, and the PLASTIC bolts are about twice the width of the old metal screws. This means when you install the seat, the seat bolts are SUPPOSED to hold the bidet attachment, also. Only, the sliding bracket(s) on the bidet attachment have screw holes that are half the size they need to be, to allow the toilet seat bolts to go through them. Now, you CAN attach the bidet attachment to the toilet without using the included (sliding) bolt brackets. But then there is nothing to stop the bidet attachment from sliding around...back, forward, tilting sideways... (basically, you'll never hit your butt that way) I have found a couple of creative workarounds. On one toilet, I was able to take long zip ties and thread them under/around the toilet seat hinge and then under/through the bidet attachment on each side. Then it was just a matter of closing the zip ties just enough to keep the bidet attachment from sliding back on either side. This effectively locked the bidet attachment in place, right where it needed to be. In my current apartment, the toilet was a bit different. It didn't look like the zip tie method was going to work. So instead, I cut pieces of styrofoam (packing material) to a width of about 1.25" wide and about .5" tall. Each block of styrofoam is about 3-4" long. I also wrapped the styrofoam blocks with plastic packing tape, to keep them clean. Then I wedged the styrofoam blocks between the toilet tank and the back of the bidet attachment. I think there is JUST enough friction to keep the blocks in place, though only time will tell if this is a long-term fix. For the moment, these blocks work great! (see the picture I uploaded) OK, this next part is VERY important. Regardless of whether your toilet seat bolts will match this greenco bidet attachment (and they probably will not), you've got another problem that is much less obvious, and will only appear over time. When you install the bidet attachment, the toilet seat bracket that holds the hinges will be PROPPED UP a bit ABOVE the level of the toilet. That is a problem. Now your SEAT HINGES are just a little bit higher than your TOILET SEAT. At first, it will seem OK. You will sit down, do your business, use the bidet to clean your butt...and you are happy with your new bidet! But over time, you will sit on the throne hundreds of times and EACH time, you are placing incredible stress on the toilet seat hinges. Yes, your weight is transferred to the toilet seat HINGES, because they are up above the toilet now. Basically, the toilet seat is supposed to take your weight while you are sitting down. But because the toilet seat hinges are ABOVE their normal attachment point, much of your weight is forced onto the HINGES, and the HINGES are not made to take that weight. Eventually, the toilet seat hinges break. What is the solution? Well, simply need to put the weight of the toilet users back on to the toilet SEAT, and take that weight off of the hinges. The easiest way I have found is to buy rubber bumpers at the hardware store (the kind that prevent cabinet doors from loudly BANGING shut). On the bottom of your toilet seat, you should see several "feet" that transfer your weight from the seat to the toilet itself. On each of those feet, use super glue to attach 1, 2 or 3 of the plastic bumpers. That way, you raise the height of the toilet seat JUST a bit, so that there is less stress on the toilet seat hinge. IT WORKS!!! The toilet seat hinge will last for years now, just like it should. The little rubber bumpers also make closing the seat quieter. (!!!!) OK, now you know the secret to really do a RELIABLE install of one of these things. It just takes a few dollars worth of materials not included and a little bit of time/effort to get it tweaked for long-term use. If Greenco were to include brackets for use on PLASTIC toilet seat bolts, and the little rubber bumpers to raise the height of the toilet seat...that would be awesome. This would only add a few minutes of effort to a job that only takes a few minutes to begin with. But the results would hold up better, over time...

The Greenco Bidet Fresh Water Spray-- Tip-Top for Your Bottom

Okay, so I’ve had an attraction/repulsion relationship with the idea of a bidet for some time, and when the opportunity to try one for a very reasonable price came along, I decided to give it a shot. Worst that happens, I throw it away and have a funny story to horrify the grandkids with, should I ever have grandkids. The unit arrived in good shape, and I familiarized myself with the installation process. I had rigid piping going from the angle valve to the toilet, and could not, for the life of me, figure out how to insert the extra fitting in between without cutting or bending the supply line, probably crimping it in the process, so I bought a replacement flexible supply line. Added a few bucks to the cost, but whatever. Installation took about 45 minutes. (I’m slow, and I kept having to go from the 2nd floor to the basement for more tools.) The hardest part was attaching the provided clear plastic tubing to the supply fitting and to the bidet’s input port. I found that a mug of piping hot water helped a lot—immerse the end of the hose in the water, wait a few minutes for it to soften, the jam it onto the fitting and screw down the connector. Bam! Done. Stupid me, once everything was put back together, I said to myself, I should open that valve and make sure water comes out. It came out all right! Blasted me right in the face! Made a mess on the walls and floor for me to towel up. But I suppose I proved that the water came out when you opened the valve, and stopped when you closed it again. When the time came, as it usually does at some point, to have a little sit and think, once the pinch-off occurred, I slowly reached for that little valve and gingerly opened fire. WOO-HOO-HOOOOOOOO, was that a blast! Lift a bloke right off the seat! And I only got to setting 3 of 5 or so. Played with the deflection lever a bit to get just the right placement, and after a few seconds, shut ‘er down and prepared to do the paperwork. One wad o’ bumwipe dried everything off and I was clean as a whistle and good to go. Well, clean, for certain values of cleanliness, I guess. It’s not like cold water is an antiseptic or disinfectant. But cleaner than I would have been with nothing but paper. My wife is scornful of the purchase, and I can’t really blame her, because I was there not too long ago, but I don’t mind—I think just being able to try it out and see whether it improves my quality of life is worth the nominal investment. If it saves on bumwipe--and it definitely does--that'll make it pay for itself in no time! If the unit lasts for even just a year, it will have been worth the nominal cost, and then I can decide whether to buy a more fancy-pants unit with all the bells and whistles. But Hiram, what about the cold water? Isn't it uncomfortable? I thought it might be, but honestly, no. Apparently, the bum doesn't have nearly as many temperature sensitive nerve endings as the hands or face. A warm water option might be nice, but then you have the issue of how warm to make it, how to get it warm enough before actually shooting the jet at your derriere, how to keep it from getting *too* hot... There are bidets that have a warm water option, so obviously someone has come up with some kind of solution, but I'm here to tell you that I don't think the cold water is particularly unpleasant, even though I went into the purchase thinking it might be. Now, there are a couple minor issues with the unit, but really, nothing worth losing a whole star over. It subtly modifies the geometry of the seat. It makes cleaning the toilet a little more difficult. While installing it, it unexpectedly twisted my fill valve and made the toilet unable to stop filling after a flush, until I realized what was going on and twisted it back. And the plastic supply hose was too long, and should have been cut down, but sizing and cutting it wasn't part of the instructions, and it was hard enough to get it onto the fittings, I'm not about to try to take it off now, cut it, and refit it. And perhaps the biggest issue, there's no interlock requiring a butt to be on the bowl before the water will flow. Which means you have to keep dexterous children and pets away from it. (You may want to keep your older kids away from it too, unless you want to explain to them why you think it's a great idea to have a jet of cold water shot up your whoopsadaisy.) But like I said, none of these individually, nor even in totality, really rises to the annoyance level needed to dock the product a star. I installed this on a Friday morning when I had the day off from work, and used it all weekend. Then on Monday when I was at work, I had to use the company restroom, and was sad that I wasn't at home so I could use my Greenco Power Washer. Greenco made a convert out of me.

Question: Does this shoot ice-cold toilet water right up your butthole?

Answer: A bit chilly, though not exactly ice cold. The water in your pipes is so cool that it doesn't even freeze in the thick of winter (and this is New England). My own experience has shown that this is a minor issue when using this product.

Question: Can this double as a drinking fountain?

Answer: LOL. Whether or whether you should drink from the toilet is a matter of personal preference.

Question: Will it clean my butthole? Or would I have to wipe afterwards as well?

Answer: Unfortunately, some people feel the need to wipe it dry. Paper is not necessary for its use.
