Kohler K-45800-4-CP Alteo Single Handle Single Hole or Centerset Bathroom Sink Faucet with Metal Drain Assembly in Polished

The faucet looks really nice and was easy to install, it is pricy but in the end it is worth it. The flow was quite low with the factory configuration and that's about the only thing I dislike about it. After taking out the flow restrictor, the flow is much better and now I can decide how much flow I want, I don't need the aerator to decide that for me. I have included some pictures showing the removal of the flow restrictor off of the backside of the aerator. After taking out the white cap, remove the pick insert. Then reinstall with the provided aerator turning key. Read more

Love this faucet! So easy to turn on & off with even a pinky finger. Good water flow but not a powerful flow which is not needed in a bathroom sink. Looks great too! Read more

This worked out so great for my new bathroom vanity. Being able to put it in as a one hole faucet really looks modern plus it is on a higher arc. One thing the lever in the back to work the drain stopper could not be used because there was not much room between the faucet and the back splash. The lever does come out at a slight angle. That was not a problem because I wanted a push pop-up drain anyway. I am really happy with the quality and the look of this faucet. Read more

The only downsides are the priceiness and a slight lack of clarity in the instructions. But I've only installed one faucet prior to this, so experienced people will likely find it a piece of cake. When installing the lever for the drain popup, there's a nylon washer that sits next to the nylon ball, but it's not shown in the instructions. The washer looks symmetrical, but it seemed I had to flip it to get it the thing to screw on right. It is built very well, no looseness anywhere, and the only thing you'll need are a couple tools and plumber's putty. Read more

This is a handsome design, and you should realize that you only need the slightly clunky base if you have a three-hole sink. They look best without the base in a one-hole sink, and the base is purely optional, fortunately. On the plus side, we got towell bars, toilet roll holder, towel ring and robe hook all from the Kohler Alteo line, providing a sleek coordinated look to the bathrooms, and we would have gotten the shower head from this line as well if we had it to do over again. We got 80% of the design quality of vastly more expensive bathroom hardware for half the price of the high end stuff--kind of like how our Mazda 3 gives us 80% of a Beemer for half the price--and still seems to have comparable reliability. Computerized manufacturing techniques have shrunk the distance between cheap and expensive products in general. Our new faucets replace cheap Home Depot house brand faucets that worked reliably without any problems for over a dozen years, while the ones we had before that were unreliable, requiring maintenance and having leakage issues that the Home Depot products didn't have. That's how much thinks have improved in a generation. But the inexpensive stuff still doesn't look at good as midrange products like the Alteo line. Also, high arc faucets like this make it easier to fill water bottles, especially the tall-ish ones bicyclists use. it's also easier to rinse after brushing your teeth if you like to stick your head under the faucet instead of using a glass. On the negative side, we found that the faucet's drain rod (the little thing you see peeping out in the back of the faucet in the photo) pulls up at an angle, which can foul on the backsplash, if you have a backsplash and/or the mounting hole is too far back. This is the sort of thing that's easy to miss when you're shopping. It's not a defect in the product--just something to need to be aware of. Likewise, it's not a defect that the faucet uses a smaller than normal aerator, but if you want to attach a valve for a pet/shampoo sprayer to the faucet, you'll need a step-up ring. Not a problem for 99% of buyers, and the step-up rings are easily available for online order. But we'd already gotten a Dawn (Taiwanese brand) single-handle faucet for our other bathroom, which has a normal-diameter aerator, and only cost a little more than the Kohler, so we went with the Dawn and returned the Kohler faucet. We also liked the design of the Dawn faucet's handle a bit more. More importantly, the flow restrictor and the aerator are a single component, so if you remove one you remove both--making the water flow unacceptable to most--whereas with the comparably styled Dawn product (AB77) they're separate pieces, so you can keep the aeration even without the flow restrictor. I think most buyers would be happy with the Kohler, unless the slightly greater design sophistication of the comparable Dawn product matters to you. One important price factor is that while the chrome versions of the Kohler and the Dawn faucets were close in price, the Dawn faucet in brushed nickel cost a lot more. So your choice could be different depending on which finish you want. Read more

Very nice fixture. Good quality, good instructions, shipped quickly. I opted to buy this instead of a less expensive model that looked similar because of the brand and the free one-day shipping on amazon. I installed it without the escutcheon (plate on the bottom) on a single hole sink. It comes with lines attached so you don't need to buy any - saves a bit of money since it's a bit expensive. Worth every penny though. You will need plumbers putty for the plastic part you bolt to the bottom of the faucet to sit on the sink as well as for the drain. Easy to use, you can look up a video on youtube. Just form a bead in your hand, roll it into a string between your palms until it is 1/2 cm thick. Press it around the bottom of the faucet and the drain where each will touch the sink. Place them and tighten, wipe away the excess. Wait a few hours for it to harden before you use or it could wash away. I have an old house so I needed some additional 1 1/4" brass tubing and a 1 1/4" to 1 1/2" adapter I bought locally. Easy installation despite that. Worst part will be getting the old faucet off. Read more

I kept watching my old (non-Kohler) vanity faucet with mineral crud seeping through the seam joining the upper and lower sections and knew it was bound to blow soon. Since I've had good experiences with Kohler kitchen faucets and not-so-much with the bathroom one, I searched for Kohler. I picked the shiny finish which arrived quickly to be installed by a licensed plumber. I chose the shiny finish and it makes me smile every time I use it. (An interesting and pleasing design feature I didn't note during the ordering process is that the handle tapers a bit from the back forward to the tip of the handle.) Read more

This faucet looks good,but is a water saver. The water flow is so low that it takes twice as long to wash your hands. That being said, I contacted Kohler with my problem and they sent new valves and aerators. I do not think the flow was better but they were very willing to try to help. Will I buy other Kohler products? Yes based on customer service Read more
