I would suggest that collette please measure the toilet rough in again based on the drain center.
Toilet rough in size 11.
Toilets are typically offered in either 10 inch 12 inch or 14 inch rough ins.
A toilet s rough in refers to the measurement dimension from the finished wall to the center of mounting holes on the floor flange.
The 12 inch rough in is by far the most common in the us.
Never measure from the molding baseboard to the flange only against the wall.
10 and 14 are also possible and you ll have a smaller selection of toilets that fit those sizes.
Follow these step by step instructions for measuring the toilet rough in.
If you measure a few times and come up with 10 or 14 inches you will need to replace with the proper size toilet.
The most common distance is 12 inches so most toilets have a 12 inch rough what is the toilet rough in standard measurement or size.
Do not measure to the baseboard molding but to the wall.
Since there is no 11 size to my knowledge it may just be that collette has a 12 standard rough in toilet but measured 11 from the back of the drain to the wall or from the center of the drain to the baseboard.
I d say 80 of toilets have a 12 rough in so don t be surprised if you do as well.
If your measurement comes out to 11 5 or 12 5 then don t worry it s likely a 12 rough in.
The standard toilet rough in distance is 212 inches but in the older homes and older toilets and even corner toilets you can find toilets with rough in distances of 10 inches to even 14 inches.
Remember the center of the toilet flange to the wall should be 12 inches.
There are however other rough in sizes.
