To level a toilet on tile, use plastic shims to eliminate any rocking before securing the base. Because tile floors are often uneven, leveling distributes the weight evenly and prevents the wax ring from breaking and leaking.
When shimming a toilet to fix a wobble or uneven base, you typically place shims in the back and along the sides near the structural points of the bowl. Avoid placing them in the front.
A toilet does not need to be perfectly level to function, but it must be completely stable and not wobble. If your bathroom floor is unlevel, you should use Example Plumber Shims (plastic or rubber) underneath the base to secure the toilet. Never overtighten the bolts to force a toilet flat, as this can crack the porcelain.
You should use specialized plastic toilet shims to level an uneven toilet. Never use wooden shims, as they will rot and compress due to bathroom humidity. For minor leveling, you can also use stainless steel washers, but plastic shims are preferred because they can be easily trimmed to size.
To fix a wobbly toilet on an uneven floor: gently snug the floor bolts, insert plastic shims into the gaps around the base, and trim them flush. Finally, seal the base with a high-quality silicone caulk to prevent shifting and keep grime out of the gaps.
What is the cheapest way to level an uneven floor?
Yes, you can absolutely use shims to level a toilet. It is the most common and effective method to stabilize a rocking toilet caused by an uneven bathroom floor.
Disadvantages
Dish soap has the ability to lubricate and break down the bonds of fats and grease. When poured into the toilet, dish soap helps lubricate the waste causing the clog, while also breaking down its structure, allowing it to easily flow down the drain.
The best way to level a toilet is by inserting plastic or rubber toilet shims under the base, rather than over-tightening the bolts, which can crack the porcelain. Place a level across the bowl, lift the low side, push the shims in to level it, and then caulk the base.
Yes, the toilet flange should sit on top of the finished vinyl plank flooring.
If shims show through beyond the toilet base, a utility knife should be used to cut off the extra for a clean look.
Because the warmer your butt, the happier your life. This may sound quick-and-dirty (because it is), but this is what Lifehackerrecommends: Slip old athletic socks onto either side of the toilet seat — that way, your behind rests comfortably on them (and not directly on that hyperborean toilet seat).
Yes, caulking around the base of a toilet is required by most plumbing codes. The International Plumbing Code (IPC) and the Uniform Plumbing Code (UPC) stipulate that the joint where a fixture contacts the floor must be sealed to create a watertight, sanitary joint.
Choosing between wood and plastic shims depends on your application. Wood shims are cheaper, easier to cut, and great for standard interior framing. Plastic (or composite) shims resist moisture and rot, making them superior for wet areas, heavy loads, and outdoor projects.
Generally, more than 3 to 4 shims in a single stack is considered too many. Stacking them too high compromises structural integrity, creates instability, and risks slippage. Instead of relying on a tall stack, use fewer but thicker shims, or address the root gap.
If your toilet still wobbles after tightening the bolts, do not over-tighten them, as this can crack the porcelain. The wobble is likely caused by an uneven floor, a broken toilet flange, or worn bolt slots. You can stabilize it by inserting shims, repairing the flange, or resetting the toilet.
Labor makes up most of the repair cost, and some plumbers may charge a flat fee for simple toilet flange replacement rather than billing an hourly rate. You can expect to pay around $45–$150 in labor out of an estimated total project cost of $60–$200.
Though the soap in the tank hack might seem like a cheap and easy way to clean your toilet tank, it can actually lead to some serious plumbing headaches. For starters, your toilet's tank is a finely tuned mechanism that's designed to flush water — not oils, not chemicals, and definitely not melting bars of soap.
The most cost-effective alternatives to self-leveling compound are portland cement and sand mixtures (for deep fills) or thin-set mortar mixed with plywood shims (for localized dips). For large areas, combining a bulk base mix with a thin top layer of premium leveler cuts costs dramatically.
