Smallest wall hung toilet length for new powder room

[downtowner]

Hi,

We are creating a new powder room inside of an existing living room and want to make it as compact as possible.

I gather code requires a 30" width, and 21" in front of the toilet.

I see that Duravit makes a toilet that is a little more than 15" long, and it can be combined with a Grohe wall unit. Does it make sense to install the wall unit for a 6" wall opening to get better flushing?

What would be the shortest toilet with bidet functionality?

Thanks in advance, Frank

I see bowls that are 21-1/4" long and longer on the Duravit site.
And then adding a bidet seat, matching to the Duravit bowl shape may be interesting. You will want to make sure that you can find a match for that.
What is a 6" wall opening?

I found this online:
Grohe 38773000 Rapid Sl 3-in-1 Set for Wall-Hung Toilet, 0.82 m

And in the comments:
Does it fit 2x4 wall
Answer:
This product will not fit in a 2x6 wall, you will want to use the 38996000 wall carrier.

So for use with 6" studs. I vaguely recall reading that this kind of unit gives a better flush. I see now that Geberit also has a unit for 6" studs. Is there any benefit to these wider units?

I gather from your replay that there is no Washlet, etc. for a 15" bowl. But a 21" bowl would accommodate one?

They make in-wall carries for both 2x6 and 2x4 stud walls.
If you're thinking of a bidet seat, you will need to check the specs to see which bowls it fits. Some of the Duravit bowls have an odd shape to them.

SOmething like the Duravit Happy D.2 uses a weirdly shaped seat, so you'd likely be stuck with only their choices and accessories. Happy D.2 Toilet wall-mounted Duravit Rimless® #222209 | Duravit
