14" Rough-In Toilet Choices

[Gary Swart]

I'd suggest you go to "Toilet Review" at the top of this page. Then "Shopping" and finally "Toto Toilets". Toto has several toilets that use their Unifit Adapter that will fit these select toilets to 10", 12" and 14" rough-in just by changing the adapter. These adapters are exclusive to Toto and only the select models. No other manufacture has anything like these. Just scroll through the numerous models listed and find the ones that use the Unifit adapter.

The unifit might give you enough room for an elongated bowl, because it moves the whole toilet back.

Edit: You know, I didn't read the dimensions carefully enough. I'm wondering what would work in the Toto line even if the rough-in was 12". The Drake round bowl is 26 3/8" just for the unit, and another 1/2" or more behind it, when placed on a 12" rough-in. On a 14", forget making 26 1/2" (you're saying that's from finished wall to front of toilet, right?). As Jim notes below, most of the Unifit-using Totos are at least 28" just for the unit.

I haven't checked, but am doubing any of the Totos that use the Unifit (which are all elongated bowls) is meets your projection dimensions. You may have a very difficult task of finding one that does...most manufactuers 14" rough-ins are 12" rough-ins with thicker tanks to fill the voild by the wall. The only one I've seen that makes a toilet that is exactly the samp projection from the wall with a 10, 12, or 14" rough-in is Toto, and those use their Unifit adapter.

I need a toilet with a 14" rough in with a maximum 26.5" length to conform to code clearance.

That sounds nearly impossible. Normally the shortest "new" toilet I've been able to find is 28-3/4" on a 14" rough, and that's using a TOTO with a 14" Unifit.

Many of the older 1920 homes used a tank on the wall and a small round bowl connected by a chrome tube.

Interesting. I'm actually kind of confused by the poster's measurements, because, as we all know, the length of the toilet itself doesn't tell you anything about how much clearance it is going to have between itself and the wall in front of it. What he really should be telling us is how much room he has forward of the center of the closet flange, because obviously he has plenty of room behind if it's a 14" rough-in.

If he doesn't care about the gap between the toilet and the finished wall behind it, then one option that may fit [let's not talk about whether it will flush well, just whether it will fit] is the Kohler Rialto.

I did a little research after seeing this post, and I'm pretty sure that Rialto is the most compact commercially-available [i.e. non-custom] unit, measuring 25 1/4" from back of tank to front of bowl. More importantly, perhaps, for this gentleman's installation, is the measurement forward of the closet flange. From the center of the closet flange forward (i.e. into the dimension that he is concerned about), the Rialto is about 14 1/8". Maybe that will do it for him.

The thing's a lowboy. And it's a Kohler. As the renter of an old AS lowboy (the Galleria), I can't say I have too much hope for the flush... But you guys probably know better...

28-1/8" on a 14" rough
Back of tank 2-7/8" to wall.

On a 14" rough-in, adding that 14-1/8" is still over 28" - more than he found acceptable. On the Totos that use the Unifit, the SAME toilet is used, only the adapter changes, so your scheme doesn't work - the toilet always projects the SAME amount into the room, regardless of the (standard 10, 12, or 14") rough-in.

In our upper bathroom, I installed a Toto Drake a few years ago, and love the G-Max flushing system. Our very small lower bathroom has a pre-1975 Eljer 5gpf toilet that has caused endless problems, with not even addressing the water consumption. The bathroom's small size and 14 inch rough makes a purchase a tough one in today's market. The Eljer has a depth of 27 inches. Due to the very small size of the bathroom, and limited access space to the shower entrance (directly across from the bowl), we need to keep the toilet's maximum depth at 28 inches or less, preferably less. Although I know the Toto elongated bowls are shorter than normal, perhaps its best to stick with a round bowl if possible. The depth limitation and the 14 inch rough in are the problems.

I noted on Toto's website the Drake II round bowl depth is 26 3/8" which would be perfect, but it appears it's only available in the standard 12 inch rough in. Is the Drake II available as special order for a 14 inch rough in? If not, does anyone have any suggestions on other Toto models which make work in this situation? From memory, I know that Toto used to offer the UniFit Rough In Adapter, but I don't know if any of the current Toto models use the UniFit system. I believe these were typically one piece toilets.

I've been fighting this problem for at least 10 years, and keeping the slow-fllushing and easily-clogged Eljer working as best as can be expected for a nearly 40 year old toilet. And, to try to come up with a viable replacement solution...?? I'd love to stay with Toto, but if any of you much more experienced folks than me have another manufacturer suggestion given the design restrictions for a 1.6gpf toilet (that actually works!), I would sincerely appreciate your advice.

Thanks.

The Drake II's cousin, which is a skirted model that can use the Unifit adapter, is called the Vespin II, and it is elongated. Click for Spec Sheet It's 28 5-16". Don't know if that 1/4" is going to be a deal-breaker for you. (The Carlyle II, which I have on a 10" rough-in on a Unifit, is the same depth.)

There is no Drake II round bowl, though. There is an original Drake round bowl. But there is no skirted version that would come with the Unifit.

Your Totos with the round-bowl options these days (original Drake, Promenade at 26-1/8, original Ultramax and/or Supreme, each at 26.5) are all unskirted and thus cannot use the Unifit, with no 14" rough-in version. As mentioned above, the 14" rough-in versions of other manufacturer's toilets, other than the Totos with the Unifit, don't actually pull the toilet back closer to the wall to compensate for the 14" rough-in anyway, and thus wouldn't save you any space. e.g. 31-5/8" on the 14" rough-in Kohler Wellworth, plus 3/4" behind it.

And when you are talking about trying to keep the toilet depth at less than 28", remember there is space between the tank and the wall. On the round Drake, that's well over an inch on a 12" rough-in. On the Vespin II, it's 3/4"-ish. You really need to measure how far out from the wall you can possibly tolerate, then calculate the toilet dimensions plus the stand-off from the finished wall. (I guess my point is that the space behind the toilet is not uniform -- Toto actually makes a toilet today that has effectively zero inches behind it, and the original Drake is just the opposite with a football field behind it -- so when you're looking at toilet size, you really have to add the size of the unit to the spec distance behind it to know how far it is going to protrude into the room.)

Toto TSU01W.10 - Toilet Rough in UniFit Adapter for 10" Rough in. Comments about TOTO UniFit 10" Rough in: Didn't think the Toto toilet we wanted was going to work, but the Unifit adapter made the toilet installation fit perfectly.

TOTO toilets that use the Unifit come standard with the 12"
You can also use a 10" or the 14" which shifts the bowl 2" in either direction.

Thanks wjcandee. I know my options are severely limited. At first, I thought my post was deleted, but after reading this thread I realized it was redirected to this thread! The current old round bowl Eljer measures exactly 27 inches from the wall to the front of the bowl. I will look into the Vespin II, as I certainly would like to stay with Toto due to the performance. I just received a call early this morning from the Toto dealer I purchased the Drake from a few years ago (Economy Plumbing Supply in Indianapolis), and the rep said there was no Toto that met my specific requirements as to max. depth. She said the only toilet they offer that meets my depth requirement is a Mansfield Model Alto #125-160 round bowl which has a 14 inch rough in and a total depth from the wall of 27.5 inches. Without researching this toilet, I imagine it would be a very poor substitute for a Toto as it's only $118, and probably is one of those 1.6gpf toilets that require more than one flush, typically plugs, or worse. I believe the 160 is considered a "builder or contractor grade" toilet, and I've read where Terry loves to move them to landfills!

Here's my big problem: from the wall where the toilet sits, the measurement from the wall to the front lip of the Fiat shower enclosure is only 44.5 inches.

I will continue to do research on this, and hopefully, will come up with a viable solution. I have no way of changing the layout of the small bathroom, and its floor is all ceramic tile so I'm stuck using whatever will best fit the current dimensions.

Thank you.

A Toto that uses the UniFIt adapter typically has 3/4" behind it to the wall. A toilet does not need a space there. You can fudge the setting of a toilet on the flange (or in this case, the adapter) by at least 1/4", and possibly a little more, so you might make it fit. I'd first measure exactly how far it is from the center of the flange to the wall (not the baseboard), then figure out where the toilet would really sit. I have both a Vespin and a Carlyle in my home, and they have been very reliable. Our water tends to eat up the rubber flapper in about 4-years or so. When they start to get soft, instead of sitting flush, the center starts to sink in and eventually it lifts the edges up so it won't seal...then, it's time for a new one. It all depends on your local water supply treatment and how often the toilet is flushed.

I'm looking for a TOTO toilet to replace in my master bathroom which has a 14" rough in. The door starts at 30 1/2" The space between the edge of the current bowl and the wall is 8"


The 3 that are in consideration are the Drake elongated CST744E, Vespin II CST474CEFG with 14" unifit adapter, and Drake round CST743E (if I must...).
Here are the problems with each:

EcoDrake CST744E - according to specs the toilet is 28" and sits 1 1/8" off the wall. In total that would be 29 1/8" but since this is for a 12" rough in I would have to add another 2" making it a total of 31 1/8". I'm worried that the door will hit the edge of the bowl. Is it possible to "skootch" the toilet an inch back?

Vespin II CST474CEFG w/ 14" unifit adapter - The water shutoff is 6" left of the center and 4 1/2" off the ground. I've seen that Terry has installed these with 5 1/2" clearance. With the valve knob, my clearance drops to around 5 1/2". I'm wondering if Terry's measurement of 5 1/2" includes the knob or is just from the center of the pipe.

EcoDrake Round CST743E - I'm a guy and prefer to install an Elongated toilet.

Any advice would be greatly appreciated. Thanks in advance

The best options are any of the Toto toilets that use the Unifit adapter. These will not only fit the rough-in space beautifully, they are a very good performing toilet and the skirted design makes them especially attractive.

[Derrick]

That's the Vespin II CST474CEFG. I should've put with the 14" rough in unifit adapter. But the concern with that was the water shutoff.

thanks for the reply!

[Gary Swart]

There are ways around that. You could use either an angle valve or elbow that would redirect the supply line parallel to the wall before making the connection to the toilet and of course, you can always cut into the wall and move the the valve. It may also work as it is, just not be as optimum a location as indicated in the installation instructions.
