An offset flange moves a toilet 1-1/2 to 2 in. On ABS, get the Jones Stephens C58434 (10.0); on PVC, the Sioux Chief 889-POM (9.7). More than 2 in. off means moving the drain.

How much offset do you need?
Enter where your drain is and the toilet’s rough-in. The checker tells you the offset and which flange covers it.
The rough-in is the distance from the finished wall to the center of the drain that a toilet is made for. Most are 12 in.; 10 in. and 14 in. models exist. If the drain is at 10-1/2 in. and you want a 12 in. toilet, you need 1-1/2 in. of offset pushing the bowl away from the wall.
Offsets also move side to side, for a toilet that sits too close to a vanity or tub. The same makers’ limits apply in any direction.
How the three compare on our spec score
Six checks from Sioux Chief’s spec sheet, Jones Stephens’ product pages and spec sheets, and the Amazon listings, equal weight.
PlumbingPicks spec score out of 10, from Sioux Chief and Jones Stephens documents read Oct 23, 2026. It is not a customer rating or our own test.
The checks are what decide whether a flange solves your problem and holds the toilet: how far it offsets, what the bolt ring is made of, whether it’s listed to the plumbing code, whether the maker publishes dimensions, whether it comes in both PVC and ABS, and whether the listing is the maker’s part.
The C58434 takes full marks with a 2 in. offset and a stainless ring. The Sioux Chief gives up a half inch of offset for a full 3 in. flow path. The C54340’s all-plastic ring costs it.
Each pick, in detail
What each maker publishes, which drains each suits, and where each lost points.
Best for ABS drains, full 2 in. offset
Jones Stephens C58434
3 x 4 in. ABS offset closet flange with stainless steel ring, less knockout
Your drain is black ABS and the toilet needs to move up to 2 in.
Skip it if
Your drain is PVC. Use the C57434 PVC version or the Sioux Chief.
The C58434 is the most complete offset flange here for ABS, and I’ve used it. It scored 10.0.
Jones Stephens’ page and spec sheet say it fits over 3 in. or inside 4 in. Schedule 40 DWV pipe, with a 2 in. offset. That’s the full offset the makers publish, a 10.
The ring is the reason to choose it: Jones Stephens calls it exclusive 400-grade stainless, with radial slots for closet bolts and 6 screw holes. A metal ring resists cracking when you tighten the toilet bolts. A 10.
Listings are complete: UPC listed and IAPMO listed, NSF certified to NSF 14-2012, and ASTM D2661 for ABS. It’s made in the USA. Tens on listing and spec sheet.
The spec sheet drawing gives a 7.00 in. ring diameter and 6.00 in. screw spacing, with 4.25 in. overall height and a 2.00 in. offset. The same sheet covers the C57434, its PVC twin, so both pipe materials are covered, a 10.
This one is less knockout, meaning there’s no molded cap to test against. If your inspector wants a test on the toilet drain, use a test plug.
Glue it with ABS cement only; ABS and PVC take different cements, and mixing them is a common callback.
Six screw holes matter on an offset: the bolt load sits off-center from the pipe, so the ring takes more twisting force than a standard flange. More screws into solid subfloor spread that load.
The radial bolt slots let you place the closet bolts anywhere around the ring, which helps square the toilet to the wall after the flange is glued.
My call: the pick for ABS bathrooms, which are common in many older and Western homes.
Best for PVC with a full 3 in. flow path
Sioux Chief 889-POM
FullFlush 3 in. PVC offset closet flange with stainless steel swivel ring

Buy it if
Your drain is PVC, you need 1-1/2 in. or less, and you want the least restriction in the drain.
Skip it if
You need a full 2 in. of offset. Use the Jones Stephens C54340.
The Sioux Chief 889-POM is the offset flange with the best flow, and I’ve used it. It scored 9.7.
Sioux Chief’s 889 series spec sheet (11-25) says the flange allows a 1.5 in. offset in any direction, with an inner diameter sized to allow full 3 in. flow for complete drainage and clog resistance. The listing adds that a 3 in. sphere passes through. That flow path is the reason to pick it.
It lost points on offset distance: 1.5 in. is an 8 against the 2 in. flanges.
The ring is 430 stainless steel and swivels, so you can line up the bolt slots after the glue sets. It’s secured to the floor and has slots for closet bolts. A 10.
Specs from the sheet: a 3 in. Schedule 40 hub to ASTM D2665 (PVC) or D2661 (ABS), UPC listed, 4.25 in. overall height, 7.00 in. ring, 5.96 in. screw centers and a 1.50 in. hub depth. Sioux Chief notes the connection fits inside most, but may not fit all, 4 in. Schedule 40 pipe.
The 889 family comes in PVC (POM) and ABS (AOM), with or without a TKO test knockout (889-POTM). This listing is the open PVC version.
Sioux Chief also makes the 889-GPOM, a gasketed version that pushes inside 4 in. pipe when there’s no stub to glue to.
The 1.5 in. hub depth is the glue surface on the 3 in. side. Cut the pipe so the full hub depth seats; a short stub leaves less cement area, and an offset flange puts more twisting force on that joint than a straight one.
The swivel ring is the practical edge on remodels: you can glue the body, let it set, then turn the ring so the bolts land square to a wall that isn’t quite where the old one was.
My call: the PVC pick whenever 1-1/2 in. is enough.
Your drain is PVC and you need between 1-1/2 and 2 in. of offset.
Skip it if
You want a metal ring. The Sioux Chief has one, with 1.5 in. of offset.
The C54340 is the PVC flange that reaches a full 2 in., and I’ve used it. It scored 9.3.
Jones Stephens says it fits over 3 in. or inside 4 in. Schedule 40 DWV pipe, with a 2 in. offset, four closet bolt slots and four mounting screw holes. Offset is a 10.
It lost points on the ring: it’s all PVC, with no metal ring, so it’s a 6. A plastic ring can crack if the toilet bolts are overtightened, and it can’t be rotated after gluing.
Listings: UPC listed and IAPMO listed, ASTM D2665-2014 and ANSI 14-2014. Jones Stephens marks it as not NSF certified. The listing check is a 10 on the UPC listing.
The spec sheet gives a 7.00 in. ring, 6.00 in. screw spacing, 4.25 in. height and a 2.00 in. offset, and covers the C54341 ABS twin as well.
Because the bolt slots are fixed in plastic, line the slots up before the glue grabs. Dry-fit it, mark it, then glue.
On a weak or rotted subfloor, back it with a repair ring or screw it into solid wood; a plastic flange relies on its screws.
Four screw holes are fewer than the C58434’s six, so use all four, with corrosion-resistant screws long enough to bite well into the subfloor.
Its 4.25 in. overall height and 7.00 in. ring match the C58434, so either fits the same floor opening and toilet footprint.
If a stainless ring matters to you on PVC, Jones Stephens’ C57434 is the PVC twin of the C58434, on the same spec sheet.
My call: the right part when you need the full 2 in. on PVC; set the bolts carefully.
The three side by side
From the makers’ spec sheets and product pages, read Oct 23, 2026.
Sources: Sioux Chief 889 series offset closet flange spec sheet (11-25); Jones Stephens C54340 and C58434 product pages and spec sheets (jonesstephens.com). All three are 3 in. hub, inside-4 in. designs.
What an offset flange can and can’t fix
Problem
Offset flange?
Better fix
Drain 1-1/2 to 2 in. off the toilet’s rough-in
Yes
—
Toilet too close to a vanity or tub by up to 2 in.
Yes, offset sideways
—
Drain 3 in. or more off
No
A 10 or 14 in. rough-in toilet, or move the drain
Flange below the finished floor
No
A spacer or extender; see our flange-too-low guide
Cracked flange ring on good pipe
No
A repair ring or a new standard flange
An offset moves the bowl across the floor, not up or down. If the flange sits below a new tile floor, that’s a height problem; toilet flange too low covers it.
Toilets come in more than one rough-in. A 10 in. or 14 in. model can solve a drain that’s 2 in. or more off without cutting the floor.
Does an offset flange hurt drainage?
The water has to turn a corner in the flange. How much room it has matters.

Not stated on the page or spec sheet
Offsets shift the opening, and some designs narrow the passage at the bend. Sioux Chief built the FullFlush design around keeping a full 3 in. path, which matches the 3 in. minimum drain most codes set for a toilet. That’s why I reach for it on PVC when 1-1/2 in. is enough.
Whichever you use, a modern toilet with a fully glazed trapway is still the biggest factor in clogs. Our best toilet guide covers that.
Code clearances to check after the move
2021 IPC 405.3.1 clearance
Minimum
Toilet centerline to a side wall or partition
15 in.
Toilet centerline to another fixture’s centerline
30 in.
Clear space in front of the toilet
21 in.
Moving a toilet sideways with an offset can eat into these. Check the side clearance after the move; 15 in. to a wall or vanity is the usual tight spot. Local codes may differ, so confirm with your inspector.
How to install an offset closet flange
1
Measure and mark
Find the toilet’s rough-in center on the floor; the flange’s offset points from the pipe to that mark.
2
Cut the pipe flush
For an inside-4 in. flange, cut the 4 in. pipe level with the subfloor; for over-3 in., leave the 3 in. stub at the right height.
3
Dry-fit and align
Turn the flange so the offset lands on your mark and the bolt slots sit parallel to the wall.
4
Glue with the right cement
PVC cement on PVC, ABS cement on ABS; hold it while the cement grabs.
5
Screw it down
Screw the ring into solid subfloor through every screw hole.
6
Set the toilet
New wax ring or wax-free seal, closet bolts in the slots, snug evenly.
A swivel ring like the Sioux Chief’s lets you square the bolt slots after the glue sets; fixed plastic rings don’t, so align them first. Our flange bolt torque guide covers tightening the toilet without cracking anything.

An inside-caulk or compression-gasket flange
Glue joints only work material to material. Joining PVC to ABS needs a transition cement your local code allows, or a mechanical coupling. On cast iron, Jones Stephens and others make inside-caulk offset flanges; that’s a different part from the three here.
How to measure your rough-in
1
Measure from the finished wall
Use the wall surface, not the baseboard or the old toilet tank.
2
Find the drain center
On an open drain, measure to the middle of the pipe; on an old flange, to the center of the closet bolts.
3
Check the toilet’s rough-in
It’s on the spec sheet or box: usually 12 in., sometimes 10 or 14 in.
4
Subtract
Rough-in minus your measurement is the offset you need; the checker above does this.
5
Check side clearance
Measure center to the nearest side wall or vanity too; the code minimum is 15 in.
The mistake I see most is measuring from the baseboard. A 3/4 in. baseboard plus drywall can make a 12 in. rough-in read as 11 in., and someone buys an offset they didn’t need. Measure twice from the wall itself, and write the number down before you go to the store.
If the old toilet is still in, the closet bolt caps mark the drain center well enough to measure from. Two caps, one on each side: the drain center sits on the line between them.
Wax ring, bolts and the offset
The toilet seals to the flange, not the pipe, so the wax ring or wax-free seal centers on the flange opening, which is where the bowl’s outlet now sits. Use a new seal every time a toilet comes up. On a flange that ends up slightly below the finished floor after tile, an extra-thick or stacked-spacer seal helps; our flange-too-low guide covers which.
Closet bolts go in the slots parallel to the wall. Snug the nuts evenly side to side and stop when the bowl stops rocking. Overtightening cracks plastic rings and porcelain alike. Cut the bolts to length and cap them once the toilet is set.
Subfloor and support
Situation
What to do
Solid plywood subfloor
Screw the ring down through every hole
Soft or rotted wood around the drain
Cut out and patch the subfloor before setting the flange
Concrete slab
Use concrete anchors in the screw holes
Tile over the subfloor
Set the flange on top of the finished floor where possible, so the wax ring seals
An offset flange carries the toilet’s weight off the pipe’s centerline, so the screws do more work than on a straight flange. A rocking toilet on an offset flange is almost always loose screws or soft subfloor, not the flange itself.
Offset flange mistakes to avoid
1
Wrong cement
PVC cement on ABS (or the reverse) won’t make a reliable joint.
2
Offset pointed the wrong way
Dry-fit and mark the direction before gluing; once it grabs, it’s set.
3
Bolt slots not parallel to the wall
On a fixed plastic ring, the toilet will sit crooked forever.
4
Forcing a 3 in. offset with shims
If the gap is more than 2 in., change the toilet or move the drain.
5
Skipping screws
Every hole gets a screw into solid material.

Questions people ask
What is the best offset toilet flange?
On our spec score, the Jones Stephens C58434 for ABS (10.0) and the Sioux Chief 889-POM for PVC (9.7).
How far can an offset toilet flange move a toilet?
1-1/2 in. for the Sioux Chief 889 series and 2 in. for the Jones Stephens flanges, per the makers.
Can an offset flange go in any direction?
Yes. Sioux Chief says 1.5 in. in any direction; turn the flange so the offset points where the bowl needs to go.
Do offset flanges clog more?
They can if the passage narrows. Sioux Chief’s FullFlush is sized for full 3 in. flow.
What if my drain is 3 in. off?
An offset flange won’t reach. Use a toilet with a different rough-in, or move the drain.
Can I use a PVC offset flange on ABS pipe?
Not with standard cement. Match the flange to the pipe, or use a code-approved transition.
Is a metal ring better?
It resists cracking when the toilet bolts are tightened. The C58434 and 889-POM have stainless rings.
Do I need a permit to move a toilet flange?
Often, if you cut or move drain pipe. Check with your local building department.
How we picked these
Why trust me
I’m Isaac Daniels, a licensed journeyman plumber in Georgia (license #JP507711), and I’ve used all three picks. Every spec here comes from Sioux Chief’s spec sheet and Jones Stephens’ product pages and spec sheets, read Oct 23, 2026. Where I add my own advice, it’s labeled as my call.
How I pick
Only glue-on plastic offset closet flanges for 3 in. or 4 in. Schedule 40 drains, with a maker spec sheet, new and in stock on Amazon, checked the same day.
Each card’s spec score comes from the six checks below. All three score 7.0 or higher.
Oatey’s Level-Fit 43500 was left out: its Amazon listing’s bullets describe tub protection, not the flange, so the listing couldn’t be matched to Oatey’s part.
The spec score, check by check
Six checks, one sixth each, 0 to 10, averaged to one decimal. The score reads makers’ published specs; it isn’t our own test, and buyers’ opinions play no part in it.
