Beats the (dated) Brondell Swash 1000 or 1400
Looks great and high in quality / value. After 5yrs using our first washer seat, a Brondell Swash 1000, and being very pleased with it, the seat cracked exactly in the back middle with a growing, pinching (ouch) gap. We're both well less than 200 pounders, LOL, and it was installed in our personal, main suite bathroom, our kids are grown and so just us 2 adults that used it. We even kept the seat settings always at lowest heat setting and in Eco Save mode, so it cannot be from degradation from long term high heat exposure, either. After 5 years, we almost rebought the 1000 and even looked at the 1400 Brondell model, but the pics and reviews online showed these models have this seat crack as a known latent defect and reportedly Brondell acting difficult about handling it as such (an epidemic defect that's out of warranty). Also, water leaks reportedly, commonly emerging as units age (although fixable with the YouTube videos out there) was concerning. I'd like to point out the basic functionality here was a "seat" first and foremost, and frankly the expensive Brondell built basic seat functionality failed miserably! Disappointed, we started shopping around ... We previously bought a Toto Neorest washer as a part of a full replacement potty unit ($$$) when doing our second bath's remodel last year because it looked so cool (looks like a big egg). It was expensive, but we were determined to have style and a washer type unit after being sold on the concept by our first Brondell Swash 1000 add-on seat experience. We love the Toto Neorest. So now that we were forced to re-shop for our main bathroom this time, Brondell was a natural, cost effect and darn good add-on solution again to just fix it or possibly replace the seat. BUT, after 5 yrs it was aging and looked it. When replacing and with a few more dollars, the competitive Toto K300, along with our added prior Toto experience, and the online reports of Brondell quality and service issues, we decided to make the leap to go Toto washers for both bathrooms. After the easy replacement install (wall electrical outlet already existing from the Brondell unit) and seeing the difference in quality (design and materials) side by side (Brondell Swash1000 and Toto K300), we also experienced what we first thought would be a less effective, more soft-cleaning (comfort) performance than what the Swash 1000 produced (or even the Toto Neorest). After using several times, we wrongly doubted its performance and now very glad we made the Toto choice again with the K300. Somehow, the Toto K300 manages to clean better and seemingly more easily (less harsh spray) than the Brondell Swash 1000 (would typically use full force to get spotlessly clean) or even its Toto big brother, big buck, Neorest (it is less harsh in capability than the Brondell, and more like the K300 in experience, but Neorest also is somehow not as a complete in clean experience - and we always paper check!). Surprisingly, this K300 best overall performance comes along and beats a similar, cost competitive, easy install, add-on unit like the Brondell Swash as well as the fully optioned Toto Neorest total potty unit we first bought ($$$)! Note Brondell's Swash 1000 and Swash 1400 models are built on the same design platform and use the same parts, including the latent defect seat, which is why I threw the 1400 into this review. Bottom line, spend the few dollars more and buy the Toto K300 for its looks, quality and performance. Toto K300 looks sleeker, lower, leaner and more modern than the Brondell Swash 1000 and 1400 and goes about performing "the job" better. Although not U.S.A. built, the Toto is marked as made in Malysia, and not China. As initially expected with the Brondell, subsequently sent to the trash bin, we certainly do not expect our Toto seat(s) to crack no matter how old they get and will update if that ever happened.

K300: a better choice than the popular Toto C5 if you want limitless warm water
Bidet seats in general are fantastic. Once you try it, it's hard to contemplate going back. I purchased this one after a bunch of research. Many online sources (e.g., Wirecutter) recommend the Toto C5 as a great bidet seat that has all the features you need at a ...sort of reasonable price. This unit has all the same features plus tankless hot water instead of a warm water reservoir. There are several advantages to this: 1) you never run out of warm water, 2) the profile of the seat gets streamlined, and 3) the K300 is more power efficient for water than the C5. The rear of this unit is about half an inch lower than the C5, but the whole seat is more sveldt. Right now the K300 is $150 or so more than the C5 and I find the price increase to be worth it for these advantages. The rest of this review would likely apply to the C5 as well, as their features sets are the same other than tankless hot water. Heated Seat: Not the foremost thing people think about with bidet seats, but it's very comforting! Two thumbs up! Ewater+ and Premist: These are great features that help make the unit less likely to need cleaning. Ewater+ is electrolyzed water that washes the wand before and after each use. Anything that minimizes your need to clean the wand is going to be a good thing, so I appreciate this one. Premist means the seat spritzes down the bowl as soon as you sit on it. This really does prevent the bowl from getting messy. Since I've had the unit, I haven't had to work on...uh...removing evidence of use, let's say. That's something I often reluctantly had to engage in prior to installing the seat. Wand Features: This unit comes with the usual suspects of oscillation and pulsation, both of which I've found to be helpful. Volume, temp, and placement are easily adjustable from the remote. Deodorization: A fan sucks fumes from the bowl through a filter. This starts as soon as you sit down, and is more aggressive for 1 minute right after you get off the seat. Shockingly, this actually works pretty well except maybe against the toughest of stinkers. I don't find the fan noise to be offensive at night, but you can deselect this function if the noise bothers you. Remote: Simple and effective. All features are available on the remote and it took one or two uses to become completely familiar with it. It's intuitive. The remote has two memories, so you and your partner can easily select your preferences in a snap. Install: Really not too difficult. Maybe 30 minutes of work. I got no leaks on the first try. You must have a GFCI outlet within 3 feet of the toilet for the cord to reach. All in all, I'm very happy with this purchase.

Waste doesn't have to be so wasteful!
Its a bidet! :) It may seem strange to talk about this, but I'm actually going to try to describe what makes this so great. I can imagine how much money is wasted on toilet paper, or paper that can be put to better use this helps with that. I always thought about this, but never had tried it and I'm impressed. I use historically a lot of toilet paper. It's quite costly. This can pay itself off in about 3 years for most, or even less if you are like me. I was using a 3-4 roles a week easy, and here you don't really need to use hardly anyway. For me it's closer to 2.5 years I'll get a pay off. And this isn't even a cheap unit. i think it's worth it though because it has self cleaning features and a warm seat, and instant hot water. It has just the key settings you need. It's really comfortable, cleaner, and healthier, and frankly just faster and less hassle. For some people the positioning of the seat it a little different you are more forward and it's more sloped you get used to it after a couple of weeks. I wish the lid were made out of a heavier gauge of plastic; it's not a huge deal. Install was easy. I have a glacier bay toilet, and a toto toilet it works on both. I've had it a while now, i waited to write this review, because toilets aren't my wheelhouse and I wanted to cover it after i get some experience. It's quite solid. The only drawback with me is I've not tried many, but i was able to still endorse this because of the key features. Unlimited warm water, and the heated seat I would think would be rather nice for most, along with the cleaning capability. I can't think of anything that would give me hesitation on it. Even the cost. It's a classic people who buy things like this end up saving in the long run. Though he life of the toilet seat, we are talking about many thousands of dollars and easier on your plumbing. It's also easier on your skin and sensitive areas which from a health perspective is advantageous and cleaner. It's like buying a coffee maker, you buy a good one and they last 20-30 years like the mocha master or a cheap one and they die in 3-5. Sometimes you buy things because they pay off in time, and they have quality. It takes some discipline or a leap of faith that the thing will last. These have solid reliability ratings. I think you should give this a try. I love mine, if it's too much you could get the step down of course, if you don't care about these featuers. It's one of these things though that since it ultimately saves you some money, if you use it it's easier to justify some of the nice feature so you keep using it if that makes sense. That's show i looked at this.

Comfortable, stable, great remote, attractive, easy to use, good water pressure.
Overall a great product and value. My family had 3 Toto washlets from the early 2000s that all lasted more than 20 years with daily use (2 finally died, one is still going), so going back to a Toto was an easy decision. the build quality is not the same as it once was, but the price is literally half of what I paid over 20 years ago, so a lesser build quality was inevitable and I’m ok with it even if I get half as long a life as I did on the old units. Great remote that is easy to use after a quick read of the manual, and lots of features and options. The unit is easy to install - no plumber required and I was able to get it on in about 45 mins and I’m slow at assembling things. It sits on the bowl in a stable way which I’m mentioning since my old unit would slip off narrower bowls (which might have more to do with the toilet design and not the Toto). I suppose it could snap the fastening cradle if a heavier person leaned to one side on a narrow bowl and the unit slips off to the side. Also, compared to my old unit I would say there is a little more wiggling in the cradle that fastens it to the bowl. Pretty sure I have screwed it in tightly enough, so I’m assuming it’s the product’s design. This isn’t a big concern, just something to be aware of. It is comfortable to sit on, but one thing to note: The top lid pretty much sits straight up. This means you really can’t lean all the way back to the tank. However, the sides of this lid are designed so they come to a sharp enough edge that it could potentially irritate your arms if they were to rub against the lid (see pic). It’s never been an issue, but if you somehow used the unit differently than me, I suppose it could be bothersome. It’s a design flaw - no way to know in advance, it’s just something you’d have to try for yourself and see how it goes. The unit is more attractive than my old one with a slightly slimmer and lower profile and a nice bright white color. Lastly, the water pressure. At full throttle, I would say the pressure is about 80% as strong as my old unit. It’s more than acceptable for all levels of hygiene, but it’s worth pointing out in case high pressure is your preference. The pressure specs according to the user manual are the same for all Toto units, so if you’re really into a high pressure stream, you’d have to do some brand shopping. So a couple of small design points, but overall a great product and value.

Outstanding!! Checks most boxes.
Installation was very easy and zero leaks on the first try. It works great!! All temperature and intensity settings for air dry, spray, and seat are pleasant & savable for two different people. I like the ability to personalize everything. It’s a comfortable size. I gave 4 stars instead of 5 because the front wash does not extend far enough to actually wash your front unless you lean your upper body forward as if tying your shoes. And I thought it had a nightlight but it does not. The air dryer is not terribly effective either. But I am still happy with this model.

I don't know how we would do without them!
We bought one of these for each of our bathrooms after seeing/trying one in a friend's house. They work great and help make you fresh and clean and the warm seat so cozy during this cold winter. The deodorizing fan works well too, seldom need to use the ceiling fan in bathroom. Comes with everything including water supply "T". Easy install except you will need a convenient AC outlet nearby. If you are lucky the longish cord will reach, if you are handy you will install an outlet for it, if you aren't stand by... an electrician will charge as much as the cost of this bidet seat!

TRADITIONAL OLD SCHOOL QUALITY IN A DISCONTINUED MODEL.
TOTO has greatly expanded its range of models which makes it confusing to make a choice. I focused on core features like regular and soft spray, pulsating and oscillating spray, continuous warm water, 5 position wand and pressure settings, and a clean, streamlined appearance without a radically sloping or curved seat cover. This one checked all the boxes and when I received it I immediately saw the same old-school quality as in my 13 yr old model. I see that TOTO has discontinued this model and I'm glad I bought it before they are sold out. The appearance is very low-key and doesn't scream bidet. I prefer traditional quality with a very nice functional remote over whistles and bells like bowl lights and large complicated, difficult to use remotes that others have complained about. The extra cost was definitely worth it.

Nearly perfect; This is the model you want
First, a critical tip that I don't think is mentioned in the manual: Do NOT use the dryer until after you've flushed. It moves quite a bit of air, and you don't want that aerosolizing fecal coliform and other nasties. The install was surprisingly easy. Working carefully, it took about 30-40 minutes and the included fittings never even threatened to leak. The instructions are unfortunately overly pictorial, a la IKEA, but they're still fairly clear. Definitely do pay attention to the various mentioned caveats in the manual, since some are unintuitive. Using it is dead simple, though learning the remote took a day or two. TOTO helpfully includes a nice permanent labeling placard for the mount that identifies what each button on the remote does. The only thing that I don't like about using the washlet is that positioning the stream side-to-side is a bit uncomfortable/awkward (YMMV if your butt is less exceedingly bony than mine). Given that there's already a dedicated control for fore-aft positioning of the wand, I would actually prefer it if the oscillating function were side to side rather than fore-aft. The soft (better described as wide) spray mode somewhat alleviates this issue, but the pressure is obviously quite a bit lower. On the bright side, TOTO seems to have engineered their mounting bolts with sufficient elasticity that shifting side to side won't loosen them over time, unlike pretty much every other seat that I've ever seen. As for the various other features that differentiate this from other TOTO models, I think that the tankless hot water option is absolutely mandatory. I've heard reports that the C5 can run out of hot water in 30-60 seconds, and that seems rushed relative to what feels completely clean. This also is much lower profile since it doesn't accommodate a tank, and you'll eventually come out ahead on cost with the 3036R or 3036 due to energy savings. I really don't know about the EWATER feature without seeing a scientific white paper, but I thought that it was worth an extra $100 to keep things as sanitary as possible, on the rationale that water alone doesn't keep your toilet bowl clean (this is the only difference between this seat, which is the 3036R, and the cheaper 3036). The dryer works, albeit slowly (1-2 minutes?), and is fairly quiet. Note though that both the dryer and washlet functionalities are going to be impeded if you're sporting an excess of posterior hair. If you were someone hoping to solve the proverbial peanut-butter-in-shag-carpet problem with this single purchase, you'd probably be disappointed. The deodorizer works exceptionally well, enough so that the bathroom fan is almost always unnecessary, which probably offsets much of the additional energy used for the hot water and dryer in summer and winter months. I've only had this for a month, so I can't speak much yet for longevity, but I expect this to last a long while. I haven't yet installed the remote's mount, and as a result the remote has already been dropped 2-3x from 2' up onto tile, without suffering a single scratch or chip that I could find, which is really impressive. TOTO does make a point of repeatedly cautioning that you shouldn't even wipe the seat with toilet paper in order to avoid scratching it; they recommend only using a wet cloth. I suspect that's overly cautious, but take their point that the extremely soft (as in Mohs hardness, not as in squishy) material in the seat is comfortable at the expense of some durability. Overall, it's a really well built and cleverly designed product that TOTO has spent a lot of time perfecting. Do make sure that you've planned how to plug it in, but otherwise, you won't regret it. Not having to wipe feels like living in the Jetsons version of the future. That interminably annoying Charmin bear can kiss my ass.

Do read before purchase
Product arrived on time in excellent condition. Excellent product. Absolutely love it. Does everything it says in the description. Water is always warm - no initial cold spray as pointed out by some. Warm dryer air will take a long time to do the job and you will use some toilet paper to finish drying. True of all bidets. Note - If you have a skirted toilet, you will need a 7/8” to 7/8” TOTO extension (available on Amazon) for connecting the tee to the water supply. Easy install.

Excellent
Have been using it now for several months. Easy to install. Great functions and the remote has all the functions you need. Couldn't be happier.

Continuous warm water
This is a high end bidet. It truly has continuous warm water. We have two other Toto bidets but they only have warm water for about 20 seconds. Fits our elongated toilet well too. Wish we had bought this model for all of our bidets. Has many other features like other bidets too.

Brilliant!
One month in an I have found this product to be extremely effective. I am not sure exactly how it works (does not seem intuitive) and do not care. I am very happy to be toilet paper free, except for drying. It is great to go through the day with the corn hole feeling ‘fresh from the shower’. In hindsight one of the cheaper models might have sufficed, I probably don’t need unlimited water and the slimmer profile. I will probably put cheaper models in all the other toilets in our home. I am somewhat concerned about whether I can take one on vacation. Not sure if it will fit in my suitcase..

Worth it
The great reviews are right. This is a terrific product that is very well thought out. More expensive than many alternatives but the large feature set and smooth operation are worth the cost. P.S.: I bought two.
