Why can't this item be shipped to CA, but another Kohler Wellworth "Classic" toilet with a HIGHER flow rate can?
Asked by: KL
Hi, this is Laura with Kohler Co. I am happy to assist you with your question. Laws restrict the selling toilets which use 1.6 gpf to flush in California. Thank you for choosing KOHLER.

Wellworth 2-Piece Elongated Toilet in Dune is rated 4.0 out of 5 by 10.

This Wellworth 2-piece 1.1 or 1.6 GPF Dual Flush Elongated Toilet in White is made in the best tradition of Kohler. I replaced another Kohler with this because I wanted the dual flush feature. I like the fact that the dual flush is incorporated into the handle itself instead of 2 buttons or 2 handles. My old toilet cut my water usage and I expect this new awesome dual flush to cut it more. I waited a little while to post my review because I wanted to be sure I like it and I have to say I love it. I only use this bathroom in the morning and the 1.1 gallon is more than enough flow.

I installed it a couple of weeks ago. Installation was quite easy. I used a foam rubber seal rather than a wax ring seal. I used my existing hold-down bolts and water supply line. I set the tank on the bowl section, threaded the nuts on fastening screws, and connected the waterline. The seat also came with the toilet. A nice quality seat. Easy to install. I love the water use and efficiency of the dual flush. This toilet is a standard height elongated bowl toilet. I do prefer a more comfort height unit.

What's there to say about a toilet boil but i have to say that it is made very well for a 2 piece set. It was the perfect height and size and was packaged great. It was easy to put into floor and is sturdy. It was super easy to put together that i didn't even need my plumber to put it in. I was able to piece together the toilet and connect all the proper hoses with ease. I highly recommend this model.

The toilet arrived broken, in spite of being packed in a very large box with a ton of foam packing material. I informed Home Depot "Seeds" customer support of this issue and explained that I would be unable to write a review because of this, yet here I am. It looks like a very nice toilet and I love the idea of a dual flush mechanism but I was unable to install it since the bowl was cracked.

I purchased an older home and needed to upgrade the toilet in the main bath. This Wellworth 2-piece dual flush was the perfect choice. Very easy to install with clear instructions. Having to pay for water, you find ways to conserve and this toilet with the choice of 1.1 or 1.6 gallons per flush goes a long way for water conservation! It is the perfect choice when updating your bathroom!

We chose this particular toilet because it had dual flush options, good for saving water. It's a great idea to have dual flush to save water, but in the case of this toilet the problem is that when you use flush option #1, the flush isn't strong enough to flush TP down. This is fine for males, but not so much for females! Flush option #2 works just fine.

I didn't want one with the flusher being a button in the top. This toilet uses a handle that's two parts. Flush part of the handle for a low power flush and use the whole handle for a full power flush. My 8 y.o. boy, 12 y.o. daughter and wife all found it easy to use after I spent 15 seconds showing them the dual flush so it's not complicated. The lower bowl design is such that it holds less water than my old style toilet. So when it's filling, the toilet doesn't put water in the bowl until the tank is half or more full. It uses a simple yet brilliant mechanism in the tank to direct the water into the lower bowl only after the upper tank is partly filled. So it uses less water on a refill as well as less water on a flush! When you do the install they say to put the wax ring on the bowl. I found it easier to put the wax ring on the pipe flange and set the bowl down over the flange bolts and ring. I also bought some clear plastic shims from Home Depot. Put them under as far as they will go and put a score mark with your pocket knife on the shim. Then I used a coping saw to deepen the score line and break it by hand and they fit under the edge of the toilet perfectly so I don't have to worry about the uneven tiles. When you do the removal you know to turn off the water and hold the handle down till it all drains. But after that I've always had problems removing a 60 pound toilet with water in the bowl. This might sound like a 'yeah duh' moment, but after you've drained all the water from the tank take 90 seconds with a plunger to have at the bowl and remove as much water as possible. It's easy and you won't have to worry about it dripping when you remove the old bowl. One thing to know, the flange bolts that connect the toilet to the floor are not included. So you need to make sure you save the old flange bolts or buy a new set. I reused my old flange bolts.
