A rocking toilet or uneven cabinet can turn a minor household repair into a frustrating project. You need a shim that matches the gap, suits the space, and provides stable support without interfering with the fixture. The right toilet shim makes the correction feel manageable, whether you are leveling a bathroom, fixing a door frame, or steadying furniture on an uneven floor.

A Deeper Look At The Lineup
You get a flexible balance of size and control with this 24-pack of 8-inch wood shims. Kiln drying removes moisture from the wood before use, helping the wedges retain their shape during installation.
The thin feathered tips are useful when you need a small correction under a cabinet, door jamb, or appliance. Compared with the later plastic wedges, this pack gives you a trim-friendly material that you can shape to the space.
What It Does Well
- Feathered tips let you slide into narrow gaps and make small adjustments.
- Kiln-dried wood supports consistent placement around doors, cabinets, and floors.
- Twenty-four shims cover repeated household repairs without an oversized bundle.
- Eight-inch length provides enough surface for trimming to suit the repair.
Practical Considerations
- You will need to trim the wood to fit a tight or irregular gap.
- Natural wood is less suitable for damp locations than the composite option.

Another Choice May Suit
Tahikem Clear Furniture Wedges suit you better when you want soft plastic shims for a small gap beneath lightweight furniture.
A small gap under a dining table calls for a controlled adjustment, not a large wedge. This clear PVC set gives you eight graduated pieces that slide into the space without drawing much attention.
You can use them beneath tables, cabinets, doors, and lighter bathroom fixtures. Their soft construction is gentler on floors than hardwood, while the textured surfaces help limit sliding as the furniture settles.
Where It Delivers
- The clear plastic remains visually unobtrusive beneath furniture.
- Soft PVC helps reduce the risk of scratching a finished floor.
- Textured surfaces add friction and resist shifting.
- Stackable wedges accommodate gaps larger than one piece can fill.
Some Limits To Know
- The maximum thickness is lower than that of the taller Tahikem wedge set.
- Eight pieces may disappear quickly across several household projects.
Quick Facts
Right Fit For
This set works well for you when the project involves lightweight furniture, modest gaps, and a finished floor you want to protect.
Consider Something Else When
Nelson Wood Shims 8-Inch 24-Pack gives you a better option for trim work where narrow feathered wood tips allow fine trimming.
You get more vertical adjustment from this Tahikem set because the thick end reaches 13/32 inch, or 10 millimeters. That additional height makes it useful for leveling a table, bed, or cabinet where the gap is more pronounced.
The tapered shape and textured upper and lower faces help the wedge grip the floor and resist sliding. You can also stack the pieces for larger corrections, although the tallest configuration still depends on the available space.
Useful Highlights
- The 10-millimeter high end handles more height than the shorter clear wedge set.
- Textured faces improve stability around frequently moved furniture.
Details To Watch
- You may need multiple wedges stacked to reach a wider gap.
- The taller profile takes more room beneath a low piece of furniture.
- Its flexible plastic suits leveling more than fine trimming work.
Who Will Love This
You benefit from these wedges when a table, bed, refrigerator, or cabinet needs more vertical correction than a shallow shim can provide.
Look Elsewhere When
Nelson Pro Pack 8-Inch Wood Shims 120-Pack suits you better for a large renovation with repeated door, floor, and cabinet adjustments.
A renovation rarely creates just one uneven point. This 120-piece box gives you enough tapered shims to move from one hinge to the next without constantly reusing a handful of small wedges.
You can trim the feathered ends for cabinet, wall, window, and door-frame corrections. Compared with the 24-pack, the larger quantity reduces interruptions during a multi-point installation, though the full box takes more room to store.
Where It Helps
- One hundred twenty pieces support repeated adjustments across a project.
- Thin tapered ends make close-fitting installation easier.
- Eight-inch length can be cut to suit doors, trim, and cabinetry.
- Kiln drying helps the shims resist shrinking, warping, and splitting.
Worth Noting
- The full box requires more storage space than a small household repair pack.
Technical Highlights
Built With In Mind
This pack is built for carpenters, remodelers, and homeowners managing several door, cabinet, floor, or trim corrections at once.
Where A Sibling Pick Shines
Nelson Waterproof Composite Shims 24-Pack gives you a better fit for bathrooms, basements, or decks where moisture resistance matters more than wood grain.
Damp corners and outdoor gaps call for a shim that can handle moisture without behaving like ordinary wood. This composite pack combines plastic with wood fiber, creating a material described as waterproof, rot-resistant, and termite-resistant.
Score lines on both faces guide clean breaks, so you can size a piece for the gap instead of cutting every wedge at random. You get a useful middle ground between the flexible Tahikem wedges and the larger cedar pieces in this lineup.
A Few Strong Suits
- Waterproof construction suits bathrooms, basements, and decks.
- Two-sided score lines support measured, consistent breaks.
- Wood fiber adds rigidity without the splintering associated with natural wood.
- The material resists rot, warping, and termite damage.
- Twenty-four pieces cover several indoor and outdoor leveling tasks.
Possible Compromises
- You give up the ability to feather the tip as finely as with thin wood shims.
- The 24-piece count is smaller than the 120-piece wood pack.
- Breaking a scored piece still requires care and a controlled surface.
The Right Fit
You benefit from this composite set when the repair may encounter moisture and you want clean breaks without handling loose wood fragments.
Swap It Out When
Nelson 16-Inch Cedar Wood Shims 42-Pack suits you better for long-span adjustments where trimable length matters more than a scored composite surface.
Some uneven floors need more than a short piece to reach the support point. These cedar wedges measure approximately 16 inches, giving you room to trim around a toilet base, door frame, cabinet, or stair component.
You get kiln-dried cedar with natural resistance to moisture, rot, and insects. Compared with the 8-inch Nelson packs, the extra length makes these more adaptable to larger spans and broader gaps, while the 42-piece count remains manageable for a serious workshop.
A Strong Showing
- Sixteen-inch length offers ample material for trimming and wider spans.
- Cedar offers natural resistance to moisture, rot, and insects.
- The 42-piece pack supports repeated repairs around a house or workshop.
Some Limits To Know
- The longer wedges need more room to store and handle.
- You will likely trim these pieces to suit most household gaps.
Core Details
Best Suited To
These cedar wedges suit you when a project needs long, trimmable supports for door frames, stairs, cabinets, or uneven floor sections.
Reach For A Different Pick When
Nelson Wood Shims 8-Inch 24-Pack gives you a better option for small household corrections that call for compact feathered tips.
What Matters Before You Level Anything
Match The Shim To The Gap
You should measure the opening before selecting a shape. A narrow cabinet gap may suit a feathered wood tip, while a deeper space may call for stacked plastic wedges or a long cedar piece that you trim to fit. Thickness matters more than length when your main goal is a small correction.
Consider The Installation Environment
Bathrooms, basements, and exterior decks can expose shims to moisture. Composite and cedar options offer more moisture resistance than ordinary wood, while clear PVC provides a softer surface beneath indoor furniture. Your floor finish and the location of the repair should guide the material choice.
Think About Quantity And Storage
A single toilet repair may need only a few pieces, while a renovation can consume shims across several doors and cabinets. The 8-piece sets work well for isolated fixes, the 24-pack offers more room for repeat tasks, and the 120-piece box suits an active project with a larger storage commitment.
Avoiding Common Shimming Errors
Mistakes Worth Dodging
Avoid choosing a shim solely by its maximum thickness, since the shape and width must match the available space. You also need to account for floor finish, clearance, and whether the shim can be trimmed without disturbing the adjacent fixture.
What Separates Premium From Basic
The more substantial options add length, larger pack counts, moisture resistance, or controlled score lines. Those features help with demanding installations, while a small repair may need nothing more than a few flexible wedges.
Frequently Asked Questions for Toilet Shims
Are Wood or Plastic Shims Better for Toilets?
Wood shims support fine trimming and typical installation work, while plastic wedges offer a softer surface and easier stacking. Your choice depends on the gap, moisture exposure, and whether you need to trim the material.
Can Shims Fix a Wobbly Toilet?
Shims can correct a minor rocking condition when the toilet is stable and the floor surface is sound. Persistent movement can point to a different issue involving the base, flange, or surrounding floor.
How Many Shims Does a Toilet Need?
The count depends on the gap and the shim’s taper. Small wedges often require several pieces, while a thicker or stacked arrangement may use fewer.
Are Larger Wedges Always Better?
A larger wedge only helps when its height and shape match the space. Oversized pieces can interfere with the toilet base or take up too much clearance.
Can Toilet Shims Be Used Outdoors?
Moisture-resistant composite and cedar options suit exposed areas better than ordinary wood. You should still confirm that the finished installation will remain stable and properly supported.
Final Verdict
The Nelson Wood Shims 8-Inch 24-Pack offer the most flexible everyday fit, with thin tapered ends for precise household adjustments. Plastic wedges work well for lightweight furniture and finished floors, while the composite, cedar, and 120-piece packs suit moisture, long spans, and larger projects. Match the material, thickness, and quantity to the actual gap before making your choice.
