Subfloor & toilet flange


I have a 90yr old home and have decided to redo the bathroom completely.

I had no problem getting the tile and concrete out so that the old 1x8 diagonal flooring is exposed & partly ripped out for the plumbers to do their thing & relocate toilet, etc...

Unfortunately, after all plumbing was done...the flange will set about 4" above that floor joists (unfinished). I have plans on a 7/8" subfloor going over the 1x8's that I will screw back into place, cement backer board, and then tile. (I will probably have to use a leveling compound on portions of the floor)

My problem is that I do not want to build up the floor so high that there is a largely noticeable step up into my bathroom. Any ideas?

Why is the toilet flange 4" over the floor joists? Can't it be lowered? It should be flush with the finished floor, so in your case, about 2 3/4" over the joists.

My plumbers said that it would not be possible to lower it because of the toilet location (i moved it from one side of the bath to another) and age of the home. They have done tons of work for me and I pretty confident with their work.

p.s.

it had something to do with draining. For some reason, it couldn't get any lower.

Drain lines should have a 1/4" of slope per linear foot toward the main drain line.
Four inches is WAY to high for a toilet flange. A toilet flange should sit flush on top of the finished floor level with only the thickness of the flange itself above finished floor level for a wax ring to seal properly.
You either have to build the entire floor up, raise the toilet, or have the plumber replumb the flange lower.

There must be a way to get that flange down. You're right, it's probably a drain-slope issue, but without changing that slope the plumber can probably use a shorter elbow, or trim some fat somewhere in the installation.
