Real reviews from WASHLET K300 - Elongated bidet seat owners

Great options, reasonable price luxury model

This Toto washlet is my second purchase. The first one I acquired approximately 10 years ago has unfortunately ceased to function due to the lack of Tosh wash, it died. I am delighted that Amazon offers a wide range of Toto washlets. I identified the model that best suited my needs, which was an upgrade from my previous model. I initially purchased it for $1,800, which is remarkable considering the significant price drop over the past decade. At that time, the dema...

This Toto washlet is my second purchase. The first one I acquired approximately 10 years ago has unfortunately ceased to function due to the lack of Tosh wash, it died. I am delighted that Amazon offers a wide range of Toto washlets. I identified the model that best suited my needs, which was an upgrade from my previous model. I initially purchased it for $1,800, which is remarkable considering the significant price drop over the past decade. At that time, the demand for these products was low, resulting in their higher cost. The upgraded model is now priced at $550. I opted for the less expensive model because the premium model only offered automatic lid closure and a specialized spray for women, and automatic bowl cleaning which I deemed unnecessary, 500 bucks less. This model is exceptional, and you will undoubtedly be satisfied with your purchase. Once you own one, you will find yourself unable to live without it. I am pleased that the price is now reasonable and the installation process is straightforward. I completed the installation within approximately an hour, drawing from my previous experience with the same model type. You will never be disappointed with Toto. All of my toilets are Toto, and I am extremely satisfied with my purchases. Ready for booty wash.

Best one out there for money

Being from Asia, I have used bidets for as long as I can remember. At one point they were impossible to find in US but they eventually made inroads in last 20 years or so. I have used atleast 8-10 different kind and this Toto bidet had been exceptional so far.

Being from Asia, I have used bidets for as long as I can remember. At one point they were impossible to find in US but they eventually made inroads in last 20 years or so. I have used atleast 8-10 different kind and this Toto bidet had been exceptional so far. Pros: - unlimited hot water, trust me you need it after you get used to bidets - easy to use remote - simple operation, options and performs flawlessely - more reliable compared to other non Toto brands that I have used (most electric one’s break in 2 years) - great fit and finish with grohe toilets (others will be ok I guess but perfect fit for grohe) Cons -none so far

Tankless heater and fits an elongated toilet

I waited a few weeks before submitting my review to make sure I was satisfied with this model. After reading a lot of reviews I am glad I spent a bit more money on the tankless model. It also comes with the proper “T” fitting to hook up the plumbing to the water supply line. I did have to install a GFI outlet near the toilet ( as shown in the picture). The bolts seemed too small for my American Standard toilet but after talking to a Toto tech , they said to flip the rubber grommet upside down and that worked fine.

The seat was incredibly easy to install, I replaced the old one in about 30 minutes. All of the required hardware is included, all you need is a screwdriver and (maybe) an adjustable wrench (don’t overtighten). It is important to note that you do need to have an electrical outlet nearby. I installed a new one a few weeks ago knowing that I was getting this. The seat itself is comfortable, but you do lose some sitting room and the opening is smaller compared to the regular toilet seat it replace...

The seat was incredibly easy to install, I replaced the old one in about 30 minutes. All of the required hardware is included, all you need is a screwdriver and (maybe) an adjustable wrench (don’t overtighten). It is important to note that you do need to have an electrical outlet nearby. I installed a new one a few weeks ago knowing that I was getting this. The seat itself is comfortable, but you do lose some sitting room and the opening is smaller compared to the regular toilet seat it replaced, because the back part of the seat that houses the electronics and such take up some of the space. It is also simple to use, there are two buttons on left that toggle through low, medium and off settings for the heated seat temperature and water temperature. The dial on the right controls the water flow and ‘aim’ (forwards for front, back for rear and center for ‘off’). The flow isn’t overpowering, but enough to get you clean, and the water warms almost instantly. The sprayer itself is contained when not it use and has a self cleaning system, while the exterior doesn’t appear to be any more difficult to clean than any other seat. It also has a light that automatically illuminates for nighttime visits. My only complaint would be that the cord could be a little longer. I was able to reach mine on the opposite side, but an extra foot or two would’ve been nice so I could tuck it away better. In summary, it may seem a little expensive at first, but when you consider what you pay for a night or two at a fancy hotel compared to something like this that will last you for years of use, I think it is totally worth it. It will also save you money on toilet paper (although you’ll still need some to dry off) and have less impact on your pipes and the environment. It will get you cleaner and the seat heater and warm water are an added comfort. Go ahead and get one…your posterior will thank you later.
