6 Best Stove Leveling Shims For Uneven Rv Floors To Use
Level your RV kitchen with ease using our guide to the 6 best stove leveling shims for uneven floors. Read our expert recommendations and stabilize your range now.
Nothing ruins a culinary attempt in a mobile home faster than a frying pan where all the oil pools aggressively to one side. RV floors are rarely perfectly level, and the constant vibration of the road can leave even a well-installed stove rocking like a ship at sea. Mastering the art of leveling isn’t just about aesthetics; it is the fundamental secret to consistent, stress-free cooking on the move.

Wobble Wedges Flexible Plastic Shims: Best Overall
Wobble Wedges are the industry standard for a reason, primarily due to their unique patented grip pattern. Their flexible plastic construction allows them to conform to the irregular gaps found between a stove base and a sub-floor, providing a stable foundation that doesn’t crack under heavy weight.
These shims are stackable and feature an interlocking design that prevents them from sliding out of place over time. Because they are made from a high-quality, long-lasting polymer, they effectively dampen vibrations, which is crucial for protecting the sensitive burners and pilot lights of an RV stove.
If you prioritize a permanent, set-it-and-forget-it solution, this is the product to choose. They are robust enough to support heavy residential-style stoves while remaining subtle enough to disappear behind the base molding.
Camco FasTen 2×2 Leveling Blocks: Most Versatile
Originally engineered for leveling RV wheels, these interlocking blocks are an unconventional but highly effective hack for large stove gaps. If the floor is severely uneven—perhaps due to a slide-out transition—these blocks offer a wider footprint than standard shims.
Because they are hollow and designed to interlock, they provide a rigid structural platform that can support significant downward pressure. This is a brilliant choice for older trailers where the sub-floor might have soft spots that require a wider distribution of weight to prevent further sagging.
While they may be overkill for minor adjustments, they are the best choice for anyone dealing with significant structural unevenness. They aren’t the most aesthetic choice, so be prepared to hide them behind a baseboard trim piece once the stove is positioned.
Impresa Hard Plastic Table Shims: Best Budget Pick
For those who need to address minor, subtle tilts, these hard plastic shims provide the necessary precision at a fraction of the cost. They come in varying thicknesses, allowing for granular adjustments that are difficult to achieve with larger, wedge-style tools.
The hard plastic resists compression, meaning the stove height won’t settle or drift once the weight is applied. They are also incredibly easy to snap or cut to size with a simple pair of heavy-duty shears, making them ideal for tight, cramped quarters where clearance is limited.
These are best suited for smaller RVs or van builds where space is at a premium and the weight of the kitchen setup is relatively light. They may not be the sturdiest option for massive residential units, but for a standard two-burner stovetop, they are perfectly functional.
GrovTec Sure-Grip Rubber Wedges: Best for Grip
When the floor is smooth laminate or linoleum, plastic shims can occasionally slide out under the weight of the stove. GrovTec’s rubber wedges solve this problem by providing a high-friction surface that essentially anchors the stove to the floor.
The natural rubber material acts as a vibration absorber, effectively quieting the rattling common during travel. Because they offer a bit of “give,” they also conform better to floor surfaces that aren’t perfectly flat, ensuring the weight is distributed evenly across the wedge.
Choose these if you are tired of your stove shifting after a long day of driving over rough roads. The grip is far superior to any rigid plastic alternative, making them the safest bet for high-vibration environments.
KaiserTales Silicone Shims: Best for High Heat
Silicone is an incredible material for the kitchen environment because it handles extreme temperature fluctuations without warping, melting, or becoming brittle. If your stove radiates heat down toward the floor, these shims are the only ones that will not degrade over time.
They possess a natural, non-slip texture that holds firm on most flooring materials, including metal, wood, and vinyl. Furthermore, they are essentially immune to the moisture and grease that inevitably spill during cooking, making them much easier to clean than porous wood or plastic alternatives.
For the serious cook who uses the stovetop frequently and at high temperatures, these are the most reliable option. They offer a unique blend of safety and durability that specialized “home” hardware simply cannot match.
Lynx Levelers: Best If You Already Own Them
Most RV owners already have a bag of these orange interlocking tiles stored in an exterior compartment. While they are usually meant for tires, they function as an excellent, heavy-duty base for a stove that needs to be raised by a full inch or more.
If you have a gap that standard wedges cannot bridge, these provide a solid, interlocking base that won’t move. They are built for extreme durability, meaning they can easily handle the weight of any residential appliance without deforming.
Only use these if your stove is recessed or if the gap is so significant that it requires a large-scale adjustment. They are bulky, but they are a fantastic way to utilize gear you likely already possess to solve a persistent kitchen problem.
Choosing Your Shims: Key Factors to Consider
The most important factor when choosing a shim is the compressibility of your floor. If the flooring material is soft carpet or thin vinyl over plywood, you need a shim with a larger surface area to prevent it from puncturing the floor under the stove’s weight.
Consider the heat proximity of your stove burners to the floor. If your stovetop is low-profile and runs hot, steer clear of cheap, low-grade plastics that might melt or deform, opting instead for silicone or heat-resistant rubber.
Finally, look at the vibration levels of your specific setup. If you travel frequently, look for materials that provide grip or vibration dampening, such as rubber or textured plastics, to prevent the stove from “walking” during transit.
Why a Level Stove is Critical for Safety & Cooking
A level stove is a primary requirement for even heat distribution in pots and pans. When a burner is tilted, oil will pool at the low point, leading to scorching on one side of your food and under-cooking on the other.
Safety is the even more critical concern. If a gas stove is significantly unlevel, it can impact the efficiency of the flame and the stability of the pilot light. This can lead to incomplete combustion, which creates carbon monoxide buildup—a serious danger in the tight, enclosed confines of a vehicle.
Additionally, most manufacturers design their internal burners and racks to operate on a horizontal plane. Running these components at a constant angle can lead to uneven wear on the metal, shortening the lifespan of your appliance significantly.
How to Level Your Stove The Right Way (in 5 Mins)
- Clear the Area: Remove the stovetop grates and any loose items.
- Use a Precision Level: Place a small bubble level on the center of the stove and check both the front-to-back and side-to-side axes.
- Identify the Low Point: Determine which corner needs to be raised.
- Insert the Shim: Carefully lift the stove—using a pry bar if necessary—and slide the shim underneath until the bubble is perfectly centered.
- Verify Stability: Ensure the stove no longer wobbles when pressure is applied to the corners.
Temporary Shim vs. Permanent Floor Fix: Which Is Best?
Temporary shims are ideal for the vast majority of RV owners, as they allow for adjustments as the vehicle settles over time. They are easy to install, inexpensive, and require no permanent modification to the floor or the appliance cabinetry.
However, if you have a significant structural tilt—often caused by a sagging floor joist or a damaged sub-floor—a shim is merely a band-aid. In these cases, a permanent fix such as installing a plywood “sub-base” or reinforcing the floor joists underneath the stove is the only way to ensure long-term integrity.
If your stove requires a shim thicker than one inch just to remain level, consider that a sign of an underlying structural issue. While shims can keep you cooking in the short term, always monitor the floor for soft spots that could indicate rot or structural failure.
Taking the time to stabilize your RV stove is a small investment that pays off every time you step into the kitchen. By choosing the right material for your specific floor and heat profile, you eliminate the frustration of uneven cooking and the risks associated with an unstable appliance. A balanced stove is the cornerstone of a functional, safe, and enjoyable mobile kitchen.
