The 270 bowl uses an offset adapter so you can adjust the rough-in from 12" to 10"

Like many dual flush toilets, there isn't much water in the bowl.

installed CAROMA 305 DUAL FLUSH few days back.
one bigggg issue is , the "water level" in the BOWL (not the tank), is so low, the porcelain gets dirty, and requires cleaning,
the "water" filled matches the "water level marker" in the TANK.
the 'three' tower like components are so complicated for me to understand, and very flimsy.
any way out , to increase the water-level in the bOWL.
Normally, no. If for some reason the fill valve is not working properly, in theory it is possible.
Take a bucket of water. Slowly pour it into the bowl. Let it sit for a minute or so, then check the level. If it goes up and stays up, it's a fill valve issue. If it won't stay up any higher, that's just the way that toilet is designed, nothing you can do about it except replace it with a different model.
Note, the dual-flush toilets can't have all that much in the bowl, because even on a low flush, it still needs to evacuate the entire amount, and refill. To keep the volume down, they can't have all that much in the bowl.

The Caroma has very little water in the bowl,
and they stay dirty.
But that has been commented on before.
I don't sell very many of the Caroma anymore.
How do you like the droplets of water on the seat when you flush it?
That's a nice bonus too.
The water level (aka water spot) in the bowl of any toilet is determined by the construction of the internal trap and is not adjustable. One of the things I really like about my Toto Dartmouth and Toto Drake is the large water spot.
Yep, I like the way Toto designed the wide but shallow waterspot. The problem being described with the Caroma is one of two reasons I decided against them. (The other was the potential for spraying material out of the bowl as I've seen in a vid.)
Call and ask about it....they may take it back...
Since you went with dual flush I assume you will want an EcoDrake model (1.28 gpf) rather than the older standard 1.6 gpf tank. I suggest adding the Sanagloss option for the cleanest possible bowl (I debated this and went with at, supply house only charged something like $20 extra for it.) Choose ADA or standard height, elongated or round according to your preferences.
You can either get the standard bowl rinse Drake or the double cyclone Drake II. I have not ever used the double cyclone so I have no comparison.
To be fair about the Caroma, and Cass knows this too, they don't plug.
They are from Australia, where water is critical.
In order to maintain a dual flush, there is very little water in the bowl,
The Toto Aquia dual flush has very little water too, as do almost all other dual flush toilets.
The Aquia does stay a bit cleaner, but for what it is, the Caroma works as advertised.
I sold dozens of the Caroma 305's to the National Park Service.
I do like the Drake models though by Toto, and the Aquia, which has been very good.
For some people with medical problems, the Caroma my be the only solution. The trapway on the Caroma is the largest on the market.
Most modern bowls do very well with a 2" trapway.
thank you very much. appreciate the inputs.
Found a way out , to keep the porcelain clean,
Before using the toilet , we flush it, (the Min-Flush) , drop folded toilet-papers around the porcelain wall
this sure a inconvenience, but keeps the porcelain clean & prevents he after-work with the brush ;-)
water savings , with little pre-work !!! (PS: not a good toilet for guest-bathroom... no way)
I notice that most toto's have a 2-1/8 trap some have a larger trap.. 2-7/16
is the larger traps much better flusher ?
looking for a 2 piece great flusher,
a certain 90 pound family member and jam a toilet. dangest thing i ever seen, and Im not talking with paper.
