The Rolls Royce of Washlets
Update after 1 year: Still works great! I dont notice the noise anymore, its very minor. Original Review: This is pure luxury. Rolls Royce of bidets. You need this in your life. A very advanced and high quality seat, easy to install, every feature out there and more in a slim package. How did they pack this many features into something so small? Amazing.

Original Review: This is pure luxury. Rolls Royce of bidets. You need this in your life. A very advanced and high quality seat, easy to install, every feature out there and more in a slim package. How did they pack this many features into something so small? Amazing. Pros: Brand name, easy install, slim profile, powerful sprays, extremely feature packed. Cons: its expensive (and if it breaks you will be sad), not easy to fix out of warranty(unless you live in California), a low buzzing sound after use (that goes away after a while), proximity sensor too sensitive (but you can apply white tape over it), not made by Toto in Japan (mine was made in Malaysia).

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.
