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.

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.

Luxury toilet experience
I was looking at upgrading to an electric bidet for a while, and Toto seems to be the best brand. I chose this model because it has unlimited hot water instead of a hot water tank that empties quickly. The bidet was much easier to install than much cheaper bidets, no fiddling with electrical tape at all. The toilet had to have the water shut off, tank drained with a couple of flushes, and then unscrew the water line and put it into the T-connector, screw the other line into the T-connector and then plug it in. The seat comes with secure metal screws, not cheap plastic ones and the washlet slides right into the screws, there is no movement while on the seat. The features work amazing, there is a heated seat, energy saving mode which turns off the heated seat and walk up feature if you’re gone for a while or overnight, and it is easy to clean and remove for cleaning under the seat. It’s only missing a toilet nightlight, but this isn’t a deal breaker for me.

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.

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.

Excellent device!
Purchased one because my wife was scheduled for shoulder surgery which would limit her mobility. Installation on our enlongated Kohler toilet was easy and secure. The bolts connecting the bidet seat to the toilet body are encased in rubber grommets that expand when the bolts are tightened, "locking" the seat in place. The water hookup was easy. However, adding the Toto connector lengthened the overall length of the toilet supply line and the hose connecting the seat itself is difficult to conceal. Others have mentioned low water pressure from the wand. I experienced that too until I cleaned mineral deposits from the supply line connectors; now - no problems! The endless warm water feature is a definite plus. The remote was a little intimidating at first but use became routine quickly. The seat itself is comfortable. The slow close seat cover seemed gigantic when first installed but now seems normal. The vent fan works well (low when you sit down, stronger when you stand up). Cleaning the entire unit periodically is easy. There's an "energy saving" setting that times out the seat heater but there's no explanation about how it works so the seat is occasionally unheated but, when you sit down, the seat heating starts and warms up in a couple of minutes. There is a small amount of noise when the bowl is sprayed, when the fan runs and during the wand cleaning cycle, but I haven't found it to be distracting. Others have commented that the drying fan isn't effective but I've found it perfectly adequate. Patience is a virtue. Also, the functions (water warmth, seat warmth, spray pressure, fan, etc.) are configurable. There is an ancillary issue that could be expensive: you'll need to have a receptacle nearby (within 4') and ideally close to floor level, so you may need to spend for an electrician to accomplish that. Pay attention to the power consumption specs in case you need an upgraded or separate circuit. Toilet paper use has been significantly reduced and personal cleanliness is perfect. There's no going back for us! After about a week of use we liked it so much that we purchased a second unit for our first floor guest restroom.

Great Bidet
Great bidet. very easy to install the unit itself. I did hire an electrician to install a new outlet near the toilet, but it was less than a 1 hour job and very simple. The unit performs exactly as described. There are cheaper models on the market, but the added features of this model are nice. Once I learned how to shut off the beeping and turn on the ECO settings, it's been great. Been using it for a few months now with no complaints. I do wish the cradle/dock for the remote was a little more "secure" given that if it falls and breaks, the whole unit will be rendered useless. I'm always afraid it will get knocked off the cradle and shatter on the ground.

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.
