KOHLER 528921 Diverter Bath Spout, Model K-10280-4, Polished Chrome

This Kohler diverter spout (K-10280-4) is threaded on the inside, near the narrow end where the water comes out. Your copper pipe needs to extend 4 1/2 inches from your tile wall, including the 1/2 inch threaded “nipple” on the end, that this diverter screws onto. The tub diverter works well, does not drip when you pull up the lever that turns on the shower, and looks much nicer than most diverters. It would normally be very easy to install, so long as the one you are replacing is also the threaded type rather than the slip-on type (Kohler’s identical slip on model that is held on with a set-screw is K-10281-4.) However, I was not so lucky. First could not figure out if my old diverter was the kind with a set screw underneath because it was so corroded underneath where the opening is near the wall (we moved into an older house). Finally figured out it was the threaded type, but could not get it off due to minerals in the water that “froze” the diverter onto the copper pipe. Tried everything to get it off. Finally saw a video instructing you to insert a screwdriver or a pliers into the end of the spout where the water comes out and use that like a lever to turn the spout counter clockwise to loosen it. No joy. Broke the threaded nipple end loose from the soldered coupler that connects it to the pipe that goes into the wall. Then had to purchase a pipe cutters soldering kit and torch and watched some videos to learn how to replace the copper pipe, added a new threaded “nipple” to the end, and soldered it all back together. After after all the time-consuming research I did, the actual soldering job was easier than I expected. With the pipe back in place and correctly 4 1/2 inches long, simple screwing on the new Kohler diverter was extremely easy. To (hopefully) keep this new one from getting stuck onto the new copper pipe, I wrapped the pipe threads with plumbers tape 3 times around clockwise, same direction as the diverter screws on. Nice product. Once all done, it works great and looks great with no dripping. Easy to install—Yes. Unless your old one is stuck on and you break your copper water pipe getting it off.

Overall very pleased but there are pros and cons. This model screws on so pipe out of wall needs threaded male end so in my case, had to buy, solder piece on. Then need a rubber strap wrench to tighten spout to wall without marring surface. So bought tool, not too much. Last potential issue deals with risk of over tightening it. Want it tight so no leaks through teflon tapes threads but if too tight, you could break your solder connections in wall, makes for bigger job. I got lucky, no leaks and no other problems. That's the cons.For pros, looks great. The base ring is not only nice looking but also helps by providing play for better fit against the wall. If pipe out of wall is not at true 90 degrees, without the ring base you will need to is caulk to cover any gaps at base. In my case caulk was still needed to seal it up but base ring helped hide the imperfect angles so you really don't see any caulk.Also, little to no pressure needed on valve stem when diverting water to and from shower. The threaded knob wore out on previous slip on type because more force was needed to divert water. With this one, lift up before turning water on and usually not even a drip from spout. And when done, just turn water off and by itself will divert from shower to spout. So threaded knob should not wear out.

All the quality you would expect from an OEM Kohler part.Importantly the color match finish was exact to the existing 3 year old trim.Being a designer matched Forte series part, the cost is justifiable.

I bought this thinking I had the screw-on type, but I ended up having the slip-fit and this still worked perfectly. My only two gripes as others have stated are that: 1) you have to glue/silicone the base plate (part that bows out and touches the wall) on to the body of the spout because it comes as two separate pieces which makes no sense. I'd imagine without caulking water would eventually leak into the faucet housing where these two parts come together and could make a mess in your wall. 2) The diverter can twist and jiggle around a lot once it is pulled up. If it is not pulled up perfectly straight and kept aligned, it might not fall back down into place all the way, or it could do a 180 and look like it is on backwards as I have seen in a buyer photo posted in the reviews. Once the two pieces are caulked together and the faucet is installed however - it looks beautiful and functions well with no leaking so far.

I purchased the slip fit version, and the install took less than 3 minutes. This replaced the same Kohler spout I had before which was showing its age. Easiest DYI I have ever done!

I was delighted to be able to order an exact replacement for our Kohler Forte slip-on bathtub spout some 25 years after I installed the first one. The diverter stopped dropping after the water was turned off, so for the last 15 years we have had to push it down after turning off the water. Now the problem is solved.

I wish this BEAUTIFUL faucet would fit the pipe I have! I measured the I.D. of the faucet and it’s 0.648” MAX. I don’t know what that is in “pipe language” but if your pipe is bigger than that, it won’t fit.And to be clear, this doesn’t screw on, there are “O” rings.

Product was used to replace Kohler tub spout with broken diverter. Arrived with slip fit diverter stripped so it was impossible to tighten the hex nut to the copper pipe. Therefore, the spout could not be installed!

Tira agua cuando subes la palanca para la regadera no augusta bien, le falta un empaque para que ajuste suena mucho, voy a tener que comparar otra, no funciona adecuadamente :/

Well made.

I purchased two of this item for mine and my wife's two days ago and delivered today with Prime.I installed very easily reusing old slip fit pieces because it doesn't contain slip fit part inside.I didn't know but it was fine to reuse them (if you refer to youtube video with this product no.,one in the video has the part in the spout but this item doesn't).There's no description about the slip fit part, so it's ok to me.Very nice finish and working very smooth.Thank you and I want to buy shower handle next time.. Already bought the head. :)

Delivery is fast. Have to return order 2 times now because manufacturer has put incorrect parts in the box! The trim piece was correct- Polished Chrome; The SPOUT itself was WRONG- Brushed Nickel!! The box outside label says ALL pieces are POLISHED CHROME and this is INCORRECT and NOT what I required for my bathroom!!! I will ONLY reorder this spout if there is ABSOLUTE CONFIRMATION First that the correct Product is in the Manufacturers Box!

We have to measure and buy a copper pipe before we can install it. why the seller don't tell us about this
