47 " from wall to wall in front of toilet ? I need to see a to scale plan and also where is the vanity or sink in relation to the toilet .

We have a 10" rough-in in our powder room also and recently replaced the toilet. There weren't very many choices for that size rough-in. Is the Toto you mentioned available in that size?

As for whether there is room for it, measure the depth (front to back) of what is there now and compare it to the measurement of what you're considering. If it's deeper, ask yourself if you really can afford to give up even a couple inches in a small bathroom. If not, you will have to get something smaller, even if it isn't a Toto.

Thanks @kandrewspa - the powder room is currently empty -- old sink and toilet already removed so not sure how deep other toilet was :/ Toto does have some 10" rough in available.... Drake model etc.

The other option is American Standard - cadet, and a few other models have a 10" rough in AND round bowl.... but the reviews here (and elsewhere) seem less passionate about the A.S. vs. the Toto....

Code in most places requires 24" of clear space minimum from the front lip of the toilet. A drawing with a dimensioned floor plan would help as your description is ambiguous.

kandrewspa-

"Smaller" toilets are typically smaller only in the sense that the bowl is rounder rather than being more elongated or oval. There is nothing in this difference in shape that should make them less reliable. The flushing process, the mechanisms, and the water use is similar for all. You just likely had a toilet that had a valve issue, but the problem had nothing to do with the fact that it was "smaller."

My design book says that you should allow 24" in front of the toilet. 47" - 24" = 23" so ideally your toilet would have a depth of 23" or less. All Toto 10"-rough-in toilets are elongated; the Drake is 28-1/8" deep. The shallowest toilet on build.com is the Signature Hardware Bradenton Two Piece Round (26") and on Home Depot the American Standard Reliant Round (25-7/8")

Thanks @wdccruise - definitely not going to be able to get 24” out of it haha if i only i knew what the previous toilet dimensions were :/

If you were willing to deal with the extra plumbing work needed for a wall-hung toilet, you could pick up a few inches. For instance, the Toto and Duravit both are about 21" deep:

And Duravit has an even more compact wall-hung toilet, the Starck 3, that only projects 19":
