My original diverter spout is a Canadian Standard Assoc. with NPT. This Kohler one is an exact replacement. I strongly advise removing your old spout to determine which type you have. It can be a slip on or like this one having pipe threads.To measure a spout, you measure from the base to the center of the down part. To remove the pipe thread one, you just turn the spout counterclockwise and to install the new one, just wrap the pipe threads with Teflon tape and screw the new one on. FYI: To install a slip-on spout where there is a NPT will require a piping change.

Item didn’t fit the sink in the bathroom. My mistake.

Always like Kohler stuff. Nice design and easy to clean

I don't why there are bad reviews on this product. It's pretty nice and sturdy. Fits perfect and doesn't leak.I have added photos to understand how it looks from inside.

Yep, you get what you pay for. The pull knob shuts down the faucet water and sends it to the shower. Just what the doctor ordered.

UPDATE as of 6/10/2017: In less than four months the diverter is starting to fail (e.g. sometimes it works, sometimes it doesn't, but it NEVER works immediately). Oftentimes I have to push my finger into the spout to get the diverter to function, which is a hassle to say the least. This faucet was working relatively well, even though it leaked a bit from day one, but it's now very clear that this is an inferior product. Time to find a better product!I bought this diverter faucet to replace the exact same model that was already installed in my home. The previous faucet sent half the water into the tub and half to the shower head (e.g. the diverter was shot/faulty). Well, the new faucet leaks as well (albeit not as much)! Given that I had to install this item to figure that out, it seems as if a return is out of the question...so...there's $30ish bucks down the drain (literally an figuratively)!Don't buy this faucet as it has a cheap, plastic diverter that doesn't work as it should. I suppose I may have received a faulty faucet, but the likelihood of a faulty faucet replacing a faulty faucet of the same model? Yeah, more likely this is just a cheaply made product that isn't meant to flawlessly work or continuously last.

missing parts, returned for refund

it works great with no leaking

For the same price as one of those Danco (all metal, but still) cheapo spouts, I got this one with just a short wait. I used a 4" nipple (could have used even 4 and 1/2"), put it on there, put just a little clear caulk around it, took care not to plug the nice little drain opening at the end, and voila: perfect diversion to shower, only a drip now and again. Works great. Thank you, Kohler! I am now no longer afraid that the spout will leak and water will run back into the wall. I think this is a special benefit of front diverters (the old one had the diverter at the back, and it was wobbly and leaky). Hope to use this for many years to come.

Important installation notes at the end!I had a really old (vintage) tub spout that was leaky and I figured wasn't helping my water pressure at the shower head. Rather than trying to repair it I figured replacing it would be easier.This unit is decent, but not as solid as the vintage unit. Not even close. But, I don't think "they" make anything like that anymore. In particular, the bypass valve that you lift feels significantly cheaper. It's just so lightweight and the actual shutoff is a simple piece of plastic that blocks the flow. If you're coming from a modern spout, I don't think you'll share my experience because you're used to this feel.When I first tested it out I was disappointed because it's 100% leak proof. Some water does drip and stream from it when closed. I really expected a 100% seal, so I was considering calling the mfgr to get their opinion. In the end I decided it's acceptable for me. It's nowhere near as bad as my old spout and I THINK it's gotten a little better after some use. Perhaps the plastic bits are settling in and breaking in a little?Look at the other reviews for notes on buying the right unit for your hookup!If you determine that you need the threaded version, like I have, be aware that you may have to fabricate a 4" extension pipe. The first thing I'd suggest is to inspect your spout for a set screw to determine which design you need. Next, I recommend that you remove your existing spout to see where the threaded connector is in the spout. For this unit it's all the way at the front of the spout, meaning it's made for a tub where the plumbing sticks out of the wall 4" with threads on the end. My plumbing has those threads barely sticking out of the wall, which meant I needed a 4" extension.I spoke with a plumber at the box store and was told there is no such thing as a prefabricated extension, which surprised me. I had to fabricate an extension consisting of a female connector, some straight 1/2" copper and a male connector. It's super cheap to do this, especially since I had the copper already. $5 or so in total. I had to solder/sweat the components together. This sounds simple, but for an average homeowner, it can be a bit tricky. At first I tried without flux. I thought the acid core would flow, but it did not. I tried several times, each time it leaked or even broke free when attempting to tighten the spout. Finally I located my flux and decided to start over (I wanted to shorten the extension as well). Success on the first try. You must use flux! Another tricky part, though, was getting just the right extension length. Think about it ... you install the spout by turning it clockwise until it's both tight and aligned correctly. If it's too tight, but not aligned yet you're stuck. So you have to be careful when assembling it. There may be some trial and error. I ended up cutting it down by 1/8th inch for the second try. I had to put quite a bit of effort into the final 1/4 turn of the spout and was worried something would break (very large pipe wrench on the spout, wrapped with a towel), but in the end it was perfectly tight against the wall, aligned and leak proof. I guess 1/16th would have been the right amount to reduce it by. Be sure to use Teflon tape on the fittings.If your plumbing is correct already, this can be installed by a home owner with little experience (and a pipe wrench) in ten minutes.I do enjoy how much easier this spout is to engage. It works well.

I'm no expert, but this is a very nice tub spout. I replaced our ten-year old one due to calcium corrosion, with this one from Kohler. A neighbor told me that his H*me Dep*t one didn't last a year, when I mentioned I was looking at Kohler. I wouldn't have found this product at any local home store, so thank you Amazon.Easy to install once the old one was removed. I recommend doing this while the hardware stores are open, just in case you need to fix the pipe that comes out of the wall.Made in Taiwan.
