How long is your current toilet? The round bowls like you currently have our less length than the elongated bowls which you have chosen.. I also would not go for a non-comfort height — Although rated as chair height, the last one seems a bit short.

I don't know about the other two brands, but I just got a new American Standard toilet and I LOVE the quality, the thorough flushing and the skirted design. They are very highly rated, too. Check this site to check on the rating for the ones you are looking at. MAP testing

@Liz H Downstairs toilet is 24" deep, master bath upstairs is about 24.5" deep.

Main purpose of changing toilets is that I want to switch to elongated.

Current heights are 16".

Why is there such a price difference between # 1 and # 2?

@olychick Thanks, I found # 1 and 3 on that site, both have scores of 1000+. I think #3 will probably be too long anyways, don't think I can fit it.

I just read about compact elongated toilets. However, I can't figure out the specific measurements that make them different than elongated toilets.

This is the closest I can find:

https://images.thdstatic.com/productImages/c30206df-7448-48ca-a879-6205fe3d6750/svn/white-kohler-one-piece-toilets-k-10491-0-a0_600.jpg

Are the seat dimensions the same as a regular elongated seat? That's what's most important to me, in this toilet change. I want the elongated shape, compared to my current round shape.

Maybe read here: https://toilethaven.com/2020/03/17/the-10-best-compact-toilets-for-small-bathrooms/
They say the compact elongated take up the same space as a round bowl, which is 2" shorter than a regular elongated bowl. Find the toilet you think will work, then find it on the manufacturer's website and find the specification sheet (often a PDF) that will have all of the dimensions you can compare to others.

So I looked at these:

https://www.amazon.com/SANIFLO-Sanicompact-Dual-flush-System-Residential/dp/B0014RQ8LI/ref=cm_cr_arp_d_product_top?ie=UTF8&th=1

But they don't have the dimensions for the seat. And I'm wary of what changes a compact elongated might do, to make it compact. Such as possibly making the seat hole smaller.

Seeing the dimensions of the Galba one, doesn't help:

It's supposed to be elongated, but it isn't any different than my current seats.

According to this, the seat hole should be 12" long:

https://www.lowes.com/pd/Project-Source-PS-Laporte-EL-CH-DF-1-PC-Black/5001935685#preview-specifications

Need the dimensions of the seat hole.

I guess this is a Lowe's brand? I don't see a spec sheet with a diagram like most name brands. I guess you could chat with them online and see if you can get a spec sheet. Usually, you can see something like this - not having it available would make me a little reticent about what I'd be getting. I'd wonder why it isn't available?

Spec sheet like you should be able to find

Yes, it's a Lowe's brand. I couldn't find a spec sheet either. I'll call them to see if I can get one.

The reviews for the flushing seem a little better. But I also want a spec sheet.

This also looks good:

https://www.totousa.com/drake-two-piece-toilet-16-08-gpf-elongated-bowl-universal-height

BUT:

I have to get it through a dealer, and they're only open from M - F, 9am - 3pm

And the seat isn't included. The seat is another $139 for black.

I'll probably consider other options first, even though it would be cool to see this in person, and take measurements. Overall, this seems too annoying, having to go to the showroom on a weekday, and that's if they even have my desired model in stock.

I love my Toto toilets. I would not buy another brand again— that is, unless I win the lottery and could afford the 5-10k smart Kohlers. 🙂

Woodbridge is out, just a bad feeling.

Swiss Madison is out, only a 1 year warranty.

American Standard has a 10 year warranty, but they don't ship to my area for some reason.

Toto seems to only have a 1 year warranty too, but they have a better reputation than Swiss Madison.

Project Source is limited lifetime, I like that.

I also like the Kohler Highline.

BTW, can someone confirm from my pics, that I do have a current round toilets, and not elongated? Thanks.

Kohler's warranty is 5 year limited.

I think it's down to Toto Drake, Project Source Laporte, Kohnler Highline. I need to get the specs for the Project Source, especially the seat and bowl, but other than that, I think I have the info that I need for now.

I can ask the handyman to help double check measurements, and see if a 27 3/8" (Toto Drake) - 29 3/4" (Kohler Highline) toilet can fit in the bathrooms.

I can move forward, to this point, at least now.

You can buy a Toto toilet online from Home Depot, delivery included.

If you can't tell from the specs if a toilet is round or elongated, just look at what size seat it takes. Seats are standard, and will be either round or elongated.

Your toilets look round to me, but you can take the lid off and get the model # from the inside the tank and google it ( or contact the maker) to make certain.

@catbuilder Amazon.com and Home Depot are restricting what Toto models I can order since I'm in California. Home Depot is restricting it to the 1.28 / 0.8 model. Amazon is restricting most models, even the 1.28 / 0.8 ones.

I haven't had such restrictions with other brands.

So I will probably go with Project Source or Kohler, since I can get the 1.6 / 1.1 model.

A local Toto dealer is likely to give the same resistance.

I think that's the same problem I was having with American Standard, most of their models seem to be restricted, even the 1.28 models. I currently have 3 American Standard 1.6 gpf models. I don't want to get a worse flush.

@olychick I will check inside the tank and confirm.

Oddly enough a Drake single flush is available on Lowes.

I guess you're right, I didn't think of the tank fitting both styles. But the new model size is the most important thing, so hopefully you will find one that fits. Don't know your budget or how extensive your remodel is, but I think wall hung toilets sometimes work in smaller areas, too. But way more $$.
I didn't go back and look at all your links or options, but found this chart on narrow depth toilets. Not sure of the other brands listed, but I just love my new American Standard toilet, after having Kohlers for 20+ years (they were fine, too) and there is one AS listed here. https://swankyden.com/best-short-depth-toilets-24-25in/
and another list - sorry if these have been posted above: https://www.sunrisespecialty.com/best-small-toilet
I just found this list that seems to be more comprehensive and what I was looking for before posting these other two: https://www.solidtoilet.com/24-25-inch-depth-toilets/

From the first link:

Maybe the Horow 8733 will be my backup option, if the handyman thinks that the others won't fit.

Also the Galba and American Standard aren't available to me.

The Horow is also 1.28 gpf, whereas it seems like I can still get a 1.6 / 1.1 Kohler through Amazon.

2nd link:

For the Saniflow, I just wish I could get seat hole dimensions, like I've been able to get for some other models. And again, I'm leaning towards a 1.6 dual flush if I can get it.

3rd link:

Yes, I wen through these earlier in the thread. That's why I then added Swiss Madison and Woodbridge to the list, for a few days, before ruling them out as both the flush power, and reviews, of Toto / Kohler / Project Source seemed better.

I'm also leaning towards getting a black toilet.

First things first, let's see how deep of a toilet the handyman thinks can realisticly fit. I think the upstairs master bathroom has a little more room around the door path, then the downstairs one.

But whatever I get, I want to try and get the same for both downstairs and upstairs.

I wasn't able to contact Lowes for Project Source specs yet, but some people on YouTube confirmed some of the dimensions.

I also need to contact Lowes and check if a 1.6 dual flush is really available to me.

In the 1970's I built a house and put in a chocolate brown toilet. Worst mistake ever; impossible to keep clean. Every water spot shows. Mineral deposits in the bowl look worse on dark colors than white. Please, reconsider black. Looks stunning but a real pain in the a$$....haha!

While I've never had a dark toilet, I kind of think every toilet looks bad after a few uses. Every white one I've had shows dirt or whatever after a few days of usage, they've always required constant cleaning if I wanted them to look best. I've usually just given up, and just cleaned it whenever I clean the whole bathroom.

I kind of think white will have some ways in which it easily shows things, and probably so will black. There's no win, it's a toilet.

Just because something can't be seen as much on a black or white toilet, doesn't mean it needs to be cleaned less.

I tend to use odor, more than visual indicators, as to when to clean.

All of this might sound conflicting. Maybe it is.

Some things we must learn for ourselves!

I just had to add that the cleaning problems I mentioned weren’t from the use of the toilet but caused by the water itself - whitish mineral deposits and where any drop of water was allowed to dry, it showed. That doesn’t happen with light toilets. And maybe you’re lucky to live where there is mineral free water! Wishing you luck!

I called Lowes main number, asking about the difference between Pro Flush and LaPorte. Despite having a 54 minute call, they weren't able to answer much, just saying that one of them looked a little longer from the picture.

They told me to call my local Lowes.

After a 37 minute hold, someone answered and hung up.

I called back. The manager transferred me to someone in plumbing.

This person was able to answer a lot of questions.

One is that the LaPorte is a 1 piece, Pro Flush a 2 piece.

Two, I asked why in the specifications, it said maximum flush was 1.6, but in the overview, it said 1.28.

He explained that to be compliant, they had to average 1.28, but to get around that, they do a full flush of 1.6, and liquids flush of 1.1. He also said the 1.1 was a little high, as other toilets that have dual flush are at 0.8.

Next, when I asked for specification drawings, he didn't have any. He said to call Project Source's main number, so I did.

This person said that it's easier to search via the item number in a search engine, then on Lowes website. I did that and found a page on lowes that had the item number, and manuals. It also said "This item is no longer sold on Lowes.com" for both. I asked why it said that, when I could find the item on lowes.com. She didn't have an answer.

I looked through the manuals, and it was just assembly instructions. No specs or measurements.

I asked about the seat dimensions.

She said that information wasn't available, and there was no way to get it.

Oh well, at least I got the seat dimensions via YouTube users.

And I got an answer at to what the 1.28 means. Perhaps that's the same for Toto, also.

The handyman will be coming for measurements on Monday. If he thinks these will fit, I'll try to get seat measurements for the Toto Drake and Kohler Highline, then make a decision.

So the handyman measured my bathrooms, and said I could fit up to 30" deep, even in the downstairs bathroom.

I had decided to get one of the Project Source toilets.

But then both went out of stock for several days.

The two piece one is now back in stock, but not the one piece yet.

Thoughts on 2 piece vs. 1 piece? I kind of want the one piece. Is it worth continuing to wait for a one piece design?

I tried calling both Lowes and Project Source, but they can't provide me with a time table.

So I'm kind of waiting indefinitely, or until I decide I'm tired of waiting.

@olychick when you had the dried mineral deposit water, how did you then clean it? Could a regular toilet bowl cleaner, clean it?

2 of the Project Source Pro Flush have been installed, one more is on its way.

I like most things about it. It has a good flush.

However, the bowl is a bit high for me. It's 17" high with the seat down.

My previous bowl was 16" with the seat down, a little over 15" with just the bowl. Or maybe it's the seat. My previous one was round, and I did want elongated. I have used elongated before elsewhere.

Can I keep the tank and the seat, and replace it with a different bowl?

I see a Kohler Wellworth Pressure Lite that's 1" more deep, 29", and 15" high without the bowl.

https://www.homedepot.com/p/KOHLER-Wellworth-Pressure-Lite-Elongated-Toilet-Bowl-Only-in-Black-Black-K-4303-7/100455550

There's also a Kohler Wellworth that's 27" deep, and 14.5" high.

https://www.homedepot.com/p/KOHLER-Wellworth-Elongated-Toilet-Bowl-Only-in-Black-Black-K-4198-7/203005652

Would this setup work, or are things not compatible? Can I mix and match the Project Source tank and seat with a Kohler Wellworth bowl?

Don't mix and match them. I'd cancel the order for the third one and get a Kohler or other toilet that's the height you want and install it in your most-used bathroom. Then move the Project Source, if you need to, to another less frequently used bathroom, which is an easy fix. Toilets come in both ADA height and comfort or standard height; sounds like you have ADA but you want standard.

Thanks. Kohler doesn't have a dual flush. I can't cancel the 3rd one since it's already on its way shipping.

I had never tried ADA height before. I didn't know it would be that big of a difference.

I can return the 3rd Project Source once it arrives. But it's hard to find another one that is dual flush; 29" or less deep; black; elongated; and standard height.

This Swiss Madison Subline is close:

https://www.homedepot.com/p/Swiss-Madison-Sublime-1-piece-1-1-1-6-GPF-Dual-Flush-Elongated-Toilet-in-Matte-Black-Seat-Included-SM-1T205MB/315769494

But it's 15.5", I think I would rather get something closer to the ~15" that I'm used to.

For a shorter person, the 17" with the seat down is a little too high.

Plus I had already ruled out Swiss Madison, just didn't get a good enough feeling after reading reviews.

I had gotten good reviews for Project Source, especially for the flushing. And after getting it installed, I definitely agree with them. The flush is great.

Also, the black toilet was a little different, but after having it for a few days, I like it.

Toto is pricier, but they have some that would check all your boxes and are well regarded. Maybe take a look at those?

I looked at them last month. Their dual flush model CST746 had a different bowl. There were a lot of complaints that the bowl for that one was shallower, which lead to undesirable effects. A few vendors stopped selling them because of that.

So the 3rd toilet, arrived broken for the second time. Again, it was damaged in shipping.

I returned it.

I might get the Toto Drake this time, since I think I want to try a lower height toilet. It won't be dual flush, but oh well.
