Toilet offset

Sep 23, 2008 12 Replies

I am building a new bathroom and was wondering if there is a standard offset from the wall for the toilet drain? Also any other tips or hints for the plumbing of the waste line would be greatly appreciated. JJ


Google is your friend as are a lot of plumbing books.

Take a yardstick and go into your bathroom. Measure from the bolthead under the plastic cap to the finish wall, and add 3/4 of an inch or so, and you should be good to go.

Standard offset is 12", but other offsets are available if you make an error. Check manufacturers web sites, the counter guys at a wholesale ditributor and similar pro sources. The box stores always have racks of good books on such subjects, and don't overlook your local library. Local building code people can be surprisingly helpful with oddball regulations specific to your location. HTH

There are a couple of standard offsets. Do some homework before you start, and it will save you a lot of grief. For that matter, you realy should have choosen all the fixtures during the design process.

except for the other standard!

Some say 12" from the center drain to the rough wall, others say 12" from the center drain to the finished wall. Best to get your toilet before plumbing/wall construction.

Its usually 12" from center drain to finished wall. You can measure the actual toilet that you pick, but the problem with that is what if a couple of years down the road you have to change the toilet, and it does not fit. Some manufacturers say their toilet is 12", but in reality they could leave an 1" or 2 space, like the Toto toilets for example. I just installed a 12" Toto and there is about a 1" space behind the toilet.

Better to have space behind the tank to fill in than to have to cut away the wall to make it fit.

12" from the center line of the waste to the finish wall is the most normal. There are some available with a 10" rough, but unusual. It would be best to have the toilet picked out ahead, but 12" should work for almost anything.
