Using the right tool saves time and ensures your floor or wall lasts for years without cracks or movement. After looking at product specs, user feedback, and common installation scenarios, we picked seven trowels that cover different needs. Need help for smaller wall tiles? That guide covers the smaller notch sizes you might need. For now, let’s focus on what works best for 12×24 tiles.
Pros
- Sawtooth pattern provides excellent mortar coverage for large tiles, reducing voids
- Sturdy thru-rivet construction ensures the blade stays securely attached to the handle
- Comfortable, ergonomic handle reduces fatigue during extended use
- Made in the USA with high-quality materials for long-lasting performance
- Lightweight design (12.3 oz) makes it easy to maneuver
Cons

The MARSHALLTOWN Sawtooth Notched Trowel (model SAW11SD) is a purpose-built tool for installing large format tiles, such as 12x24 inch or larger. Unlike traditional square-notch trowels, the sawtooth pattern creates ridges that collapse more easily under the tile, leading to improved mortar coverage and reduced voids. This trowel is an excellent choice for DIY homeowners tackling a bathroom or kitchen floor, as well as professional contractors and tilers who demand consistent results on high-end jobs.
In terms of performance, user reviews consistently highlight the trowel's ability to achieve minimum 95% coverage, which is critical for preventing tile lippage and ensuring a strong bond. The hard-tempered steel blade holds up well to repeated use, and the sawtooth notches maintain their shape over time. Many users note that the ergonomic DuraSoft handle provides a comfortable, confident grip even when hands are wet from thin-set. The thru-rivet mounting connects the blade to the aluminum alloy Xtralite mount, creating a durable assembly that won't loosen during heavy use.
Build quality is a standout feature. The blade is made of hard-tempered steel, and the mounting is an aluminum alloy that keeps the overall weight low (just 12.3 ounces). The handle is made of a soft, long-lasting material that reduces fatigue. The entire tool is assembled in the USA with global materials, which adds to its appeal for those who prefer American-made products. The finish is a brushed steel, and the red handle provides a nice visual contrast.
Storage and maintenance are straightforward. The trowel can be cleaned with a solvent like mineral spirits to remove uncured thin-set, and wiping it down after use prevents rust. It fits easily into a standard tool bag or tray. There is no included case, but the compact size (11.5 x 4.57 inches) makes it easy to store.
A realistic limitation is that a few users have reported receiving a trowel with a bent tooth, which suggests occasional quality control issues. However, most reviews praise the tool's overall quality. Additionally, if you are used to a square-notch trowel, the sawtooth pattern may require a brief adjustment period to achieve optimal coverage. Some users also note that the trowel is not always available at local home centers, so ordering online is often necessary.
Overall, the MARSHALLTOWN Sawtooth Notched Trowel offers excellent value for anyone working with large format tiles. Its combination of thoughtful design, durable construction, and ergonomic comfort makes it a worthwhile investment for both DIYers and professionals. If you are looking to improve your tile installation results, this tool is a solid choice.
The MARSHALLTOWN Sawtooth Notched Trowel is built to last, with a focus on durability and reliability. The blade is made from hard-tempered steel, which resists bending and maintains sharp notches through many jobs. The mounting is aluminum alloy Xtralite, which reduces weight while providing a strong foundation. The thru-rivet connection between the blade and mounting is a key feature: it eliminates the risk of the blade separating from the handle, a common failure point in lower-quality trowels. The DuraSoft handle is molded onto the mount, providing a seamless, secure grip that won't slip or rotate. This trowel is proudly made in the USA with global materials, reflecting a commitment to quality control and craftsmanship.
The primary advantage of the sawtooth notch pattern is improved mortar coverage for large format tiles. Unlike square notches that hold a rigid ridge, the sawtooth pattern's ridges collapse more easily under the weight of the tile, spreading the thin-set evenly and reducing air pockets. According to product specifications, this trowel achieves minimum 95% coverage, which is critical for preventing lippage and ensuring a strong bond. Users report that this trowel works exceptionally well with 12x24 inch tiles and larger formats. The blade's hard-tempered steel maintains its shape, so the notches remain consistent throughout the job. The ergonomic handle allows for comfortable extended use, making it easier to maintain a steady hand and apply even pressure. Overall, performance is excellent for its intended application.
Pros
- Large 24-inch width speeds up coverage on big floor tiles, improving productivity
- Square notches provide consistent mortar depth and spacing for professional-looking results
- Aluminum and stainless steel construction is lightweight yet durable, resisting rust
- Comfortable handle reduces hand strain during extended use
Cons
- 24-inch length may be cumbersome for small or tight areas like bathroom corners
- Only one notch size (2/5 inch) limits versatility for different tile thicknesses
- Some users may prefer a wooden handle for better grip in wet conditions
The BAOSHISHAN 24-inch Large Tile Trowel is a purpose-built tool for anyone working with large-format tiles. Unlike standard trowels that require multiple passes, this 24-inch wide model lets you spread mortar across a full tile length in one sweep. It's an ideal choice for professional contractors, tile setters, and dedicated DIY homeowners who are installing large floor tiles or slabs.
Based on the product specifications and user feedback, the 2/5 inch square notches deliver a consistent mortar bed that helps prevent lippage and ensures strong adhesion. The square notch design is preferred for large tiles because it provides excellent coverage while allowing the tile to bed evenly. Whether you're working on a new construction floor, a basement remodel, or a kitchen backsplash with oversized tiles, this trowel can help you work faster and more accurately.
The build quality is a strong point here. The aluminum alloy frame makes the trowel surprisingly light for its size, which reduces arm fatigue during long days on the job. The stainless steel sawtooth rack is corrosion-resistant, so it won't rust even when left in a damp tool bag overnight. The handle is ergonomically shaped and provides a secure grip, though it might feel slick if your hands are covered in thinset. Overall, this tool feels solid and well-balanced.
In terms of ease of use, the trowel requires minimal setup just attach a handle if needed (most come ready to use). After use, cleaning involves rinsing with water before the mortar sets. Because it's large, storing it requires a bit of space a 24-inch tool won't fit in a standard toolbox, but it can hang on a pegboard or lie flat in a tool cart. Maintenance is simple: keep the notches clean and dry.
A realistic limitation is that the one notch size (2/5 inch) means it's not a one-size-fits-all solution. For thinner tiles or smaller mosaics, you might need a different trowel. Additionally, its size can be awkward in tight spaces like closets or narrow hallways. But for its intended purpose installing large floor tiles it excels.
If you regularly lay tile or are planning a big DIY flooring project, this BAOSHISHAN trowel is a practical investment. It's built to handle heavy use, delivers consistent results, and won't break the bank. For contractors on a job site or homeowners tackling a large renovation, this trowel can help you achieve professional-grade tile work with less effort.
The BAOSHISHAN tile trowel is constructed with an aluminum alloy frame and stainless steel sawtooth rack. Aluminum keeps the tool lightweight about 1.32 pounds so it's easy to maneuver over large areas. The stainless steel notches resist rust and wear, maintaining their sharp edges for dozens of projects. The handle is attached securely and feels comfortable during use. Overall, the materials are a good match for daily professional use or regular DIY work.
On a jobsite, speed and consistency matter. The 24-inch width allows you to spread mortar quickly, reducing the number of passes needed. The square notches produce even ridges, which helps prevent tile settling and lippage. This trowel is particularly effective for large-format tiles, porcelain slabs, and natural stone. It's well-suited for contractors doing new construction, remodels, or commercial tile work. For workshops, it earns a spot on the pegboard for quick access during bathroom or kitchen projects.
Pros
- Sturdy aluminum frame and stainless steel blade hold up well on tough mortar and thin-set.
- Baffles on both sides contain adhesive effectively, minimizing mess and waste.
- Large 24-inch length covers wide areas quickly, ideal for large-format tiles.
- Lightweight construction reduces user fatigue on extended jobs.
- Foldable feature makes storage and transport convenient.
Cons
- At 2/5-inch notch depth, it may not be suitable for small tiles or thin-set applications requiring a smaller notch.
- Some users may prefer a wooden handle for better grip, as the aluminum handle can get slippery with wet hands.
- The trowel is relatively long, which might feel unwieldy in tight spaces or for beginners.
The Mxmoonfree 24-inch Large Tile Trowel is a professional-grade hand tool designed for spreading mortar or adhesive on large-format tiles and flooring. This square notch trowel features a 2/5-inch by 2/5-inch notch pattern, which creates consistent ridges for optimal tile adhesion. It's built with a lightweight aluminum frame and a stainless steel sawtooth rack, offering a good balance of strength and corrosion resistance.
This trowel is best suited for DIY homeowners, contractors, masons, and tilers who regularly work with large tiles (12x24 inches or bigger) and need to cover large floor or wall areas efficiently. The 24-inch width allows you to spread adhesive over a broader area in each pass, reducing the number of strokes and speeding up the installation process. The side baffles are a practical addition—they prevent mortar from overflowing off the edges, keeping your work cleaner and reducing waste.
In real-world use, the trowel's performance is reliable. The stainless steel notches stay sharp and resist wear from abrasive thin-set or mortar. The aluminum frame is strong enough to handle the pressure of spreading thick adhesive without flexing. The ergonomic handle provides a comfortable grip, though some users might find it a bit slippery with wet hands. The foldable design is a nice touch for storage—it folds down to a more compact size, making it easier to fit into a tool bag or on a shelf.
Build quality is solid for the price point. The aluminum frame is lightweight yet durable, and the stainless steel blade is securely attached. The trowel feels balanced in hand, reducing fatigue during long tiling sessions. Maintenance is straightforward: just rinse off excess mortar after use and wipe dry to prevent rust on the blade. The foldable hinge is well-constructed and shows no signs of loosening after repeated use.
One realistic limitation is that the 2/5-inch notch depth is specific to larger tiles and thicker adhesive applications. For small mosaic tiles or thin-set applications requiring a smaller notch (like 1/4 inch), this trowel may not be the best choice. Also, the long length can be awkward in tight corners or small bathrooms. However, for its intended use—large tile installations in open areas—it performs admirably.
Overall, the Mxmoonfree 24-inch square notch trowel is a practical investment for anyone doing serious tiling work. It offers good durability, efficient coverage, and thoughtful features like baffles and foldability. If you're a contractor or a dedicated DIYer tackling a large floor or wall tiling project, this trowel will help you get the job done faster and with better results.

- Comfortable cork handle provides a secure grip even with wet hands
- Durable stainless steel blade and aluminum shank resist corrosion and wear
- Designed specifically for large-format tiles, reducing the need for back buttering
- Reinforced rivets add extra strength for demanding professional use
Cons

- Premium price point compared to basic trowels, but justified by build quality
The QEP Euro Notch Cork Handle XL Stainless Steel Trowel is a specialized tool aimed at tile installers, contractors, and serious DIY homeowners who work with large-format tiles. Unlike standard trowels, its alternating notch pattern creates a zipper effect that closes gaps between the subfloor, thinset, and tile, reducing voids and eliminating the need to back butter each piece. This design is particularly beneficial for natural stone, quarry tile, pavers, Saltillo, and ceramic tiles 12x12 inches or larger.
Performance-wise, this trowel delivers a consistent mortar bed every time. The tempered stainless steel blade resists rust and holds up well under repeated use, while the aluminum shank with reinforced exposed rivets adds structural integrity. Users will appreciate how the cork handle provides a comfortable, non-slip grip even when hands are wet or sweaty, which is a common issue on job sites. The blade measures 12 x 4.5 inches, offering good coverage for spreading thinset or medium-bed mortar efficiently.
Build quality is a strong point. The stainless steel blade is heat-treated for durability, and the shank is designed to withstand the torque of spreading thick mortar. The cork handle is ergonomically shaped to reduce hand fatigue during long installations. While the trowel is lightweight at just 0.32 kg, it feels solid in hand. Maintenance is straightforward: rinse off mortar residue after use and dry the blade to prevent any potential staining, though the stainless steel resists corrosion well.
Storage is simple thanks to its compact size, fitting easily into a tool bag or on a shelf. No special case is included, but the trowel’s durable construction means it can handle being tossed in with other tools. One realistic limitation is that this trowel is purpose-built for large-format tile work; it may not be ideal for smaller tiles or non-tile applications. Additionally, the cork handle, while comfortable, can absorb moisture if left wet, so drying it after cleaning is recommended to extend its life.
For contractors or DIYers tackling a big tiling project, this trowel offers a clear advantage in speed and consistency. The reduced need to back butter tiles can save significant time, and the consistent mortar bed helps prevent lippage and bond failures. Based on product specifications and user feedback, this is a reliable choice for anyone serious about tile installation.

Pros
- Durable aluminum and stainless steel construction holds up to daily job site demands.
- Large 24-inch notched area speeds up mortar application on big tile projects.
- Baffle system keeps the spread tidy and reduces clean-up time.
- Comfortable to handle and lightweight, especially for overhead or vertical wall work.
- Comes with free work gloves for added value.
Cons
- Fixed 2/5-inch notch size may not be ideal for small tiles that require a different pattern.
- Manual tool requires physical effort; not as fast as powered options for very large floors.
- No carrying case included, so storage requires a bit of planning to keep the notches protected.
The Mxmoonfree 24-inch square notch trowel is a dedicated manual tool designed for applying mortar or adhesive evenly across large wall tiles. It caters to a wide range of users from DIY homeowners remodeling a bathroom to professional contractors working on commercial tiling projects. Rather than relying on batteries or motors, this hand-powered trowel gives you direct control over mortar thickness and coverage.
In real-world use, the trowel's key advantage is its efficient leveling capability. The wide 24-inch notched section lets you cover substantial area in a single pass, which can cut down installation time noticeably. The side baffles are a neat addition - they prevent mortar from spilling over the edges, so you get a clean spread without waste. User reviews mention that it works great for spreading glue behind shower surrounds and large-format tiles, delivering even adhesion without hollow spots.
Build quality is solid: the frame is made from aluminum alloy, which keeps the tool light at only 2.35 pounds, while the notched blade is stainless steel for corrosion resistance and long wear. The sawtooth rack is firmly attached and shows no signs of bending under normal pressure. This combination means the trowel can handle repeated use on job sites or in home workshops without deteriorating quickly. The included working gloves are a small but appreciated bonus for comfort.
Ease of use is straightforward - there's no setup required beyond taking it out of the packaging. Cleaning after a job is simple because the stainless steel notches don't let dried mortar stick as badly as some other materials. For storage, the 39-inch overall length means it needs a longer spot in your toolbox or a pegboard hook, but it's not overly bulky. Maintenance involves just wiping it down and occasionally checking the notches for damage.
A realistic limitation is that the 2/5-inch notch size is fixed - this pattern works best for wall tiles and large-format floor tiles. If you're working with smaller mosaics or need a different notch depth, you'll want a second trowel. Also, because this is a manual tool, you'll be applying physical effort; it's not a substitute for a power vibrator on large commercial floors, but for most wall tiling jobs it's more than adequate.
For DIYers tackling a kitchen backsplash, a bathroom remodel, or pros who need a reliable hand tool for everyday tiling, this Mxmoonfree trowel offers good value. It's built to last, speeds up the mortar application process, and includes thoughtful design features that make the job cleaner. If you're looking for an efficient, no-fuss way to level large tiles, this trowel is worth considering.
The Mxmoonfree trowel is constructed with an aluminum alloy frame that provides a good strength-to-weight ratio. The notched blade is made from stainless steel, which resists rust and stands up to abrasive mortar compounds. The handle is securely riveted and feels comfortable even with gloved hands. The side baffles are welded cleanly and should hold up well over time. Overall, the materials suggest this trowel can handle regular use on job sites without falling apart quickly. Just keep it dry after cleaning to maintain the aluminum finish.

- Brand Hubaow is relatively new, so long-term durability feedback is limited based on available reviews
If you are laying large-format tiles, having the right trowel can make or break your project. The Hubaow 2-Pack 24-Inch Large Tile Trowel is designed specifically for spreading thin-set mortar on big tiles, and it brings a combination of size, durability, and practicality that both DIY homeowners and professional tilers will appreciate.
This trowel features a 24-inch stainless steel serrated stand with a 2/5 x 2/5 inch square notch pattern. That notch size is ideal for large tiles, as it provides the right amount of adhesive coverage and transfer to ensure a solid bond. The stainless steel construction resists rust and wear, so the notches stay sharp even after repeated use. The frame is made from an aluminum alloy, which keeps the tool lightweight enough for extended use while still being strong enough to handle the demands of a busy jobsite.
For contractors, tilers, and serious DIYers, the 24-inch length is a major advantage. It allows you to cover more area with each pass, speeding up the process on floors, walls, or countertops. The two-pack is especially handy for large projects, giving you a backup trowel or letting two workers spread mortar simultaneously. The hand-powered design gives you full control over the adhesive depth and pattern, which is critical for avoiding lippage and ensuring a flat tile installation.
Build quality appears solid based on the product specs. The aluminum alloy frame resists bending or warping, and the stainless steel serrated edge is securely attached. The trowel weighs about 2.93 pounds, which is reasonable for a tool of this size. Storage is straightforward, as the trowels can be hung on a pegboard or stored flat in a toolbox. Cleaning requires rinsing with water after use to prevent mortar from hardening on the stainless steel.
One realistic limitation is that the 2/5-inch notch depth may not be suitable for all tile sizes or adhesive types. Some large tiles require a deeper notch or a different pattern, so check your thin-set manufacturer's recommendations. Also, the 24-inch length can feel a bit cumbersome in tight spaces or for overhead work. The Hubaow brand is relatively new, so long-term durability feedback is limited, but the materials used suggest good longevity.
Overall, the Hubaow 2-Pack 24-Inch Large Tile Trowel is a practical choice for anyone working with large-format tiles. It offers a good balance of size, durability, and value. Whether you are a contractor tackling a commercial floor or a DIYer remodeling a bathroom, this trowel set can help you get the job done efficiently and with professional results.
Pros
- Magnesium shank significantly reduces weight without sacrificing strength, perfect for long work sessions
- Beveled blade glides smoothly over sheetrock, minimizing drag and improving finish quality
- Ergonomic handle with soft TPR grip feels comfortable even when wet or sweaty
Cons
- The 12x4 size may be too small for large-area flat finishing; consider a wider trowel for big walls
- Premium stainless steel blade is more expensive than standard carbon steel options
- No included carrying case or protective cover for the blade, requiring careful storage
The Goldblatt RED stainless steel finishing trowel is a professional-grade tool designed for drywall finishing, plastering, and masonry work. Its 12-inch by 4-inch blade is crafted from high-quality stainless steel, offering excellent wear and corrosion resistance for lasting performance on the jobsite. What sets this trowel apart is its magnesium shank, which is 10% lighter than traditional aluminum yet delivers 20% greater strength. This combination makes it an ideal choice for DIY homeowners, drywall contractors, and plasterers who need to reduce hand fatigue during extended use.
In real-world use, the beveled blade edge provides enhanced stability and a larger load capacity, allowing for smooth, even application of joint compound or plaster. Users who have tried it report that the trowel glides effortlessly across sheetrock, reducing drag and improving finish quality. The ergonomic handle, made from PP+TPR material, offers a secure, comfortable grip that helps prevent slipping, even when hands are wet or tired. This is especially beneficial for masons and construction workers who spend hours on their feet applying finish coats.
Build quality is solid throughout. The stainless steel blade resists rust and staining, while the rivet connection uses stainless steel hardware that boasts 2.5 times stronger joint stability compared to conventional trowels. This means the blade stays firmly attached to the shank under heavy pressure, which is critical for professional users who demand reliability. The magnesium shank itself is corrosion-resistant and does not add unnecessary weight, so the trowel feels balanced in hand.
Storage and maintenance are straightforward. Since there is no included case, you will want to store the trowel in a clean, dry tool bag or drawer to protect the blade edge. Cleaning requires a simple wipe-down with a damp cloth after each use; the stainless steel material makes rust a non-issue if basic care is taken. The lightweight design also makes it easy to carry in a bucket or toolbox without adding bulk.
One realistic limitation is the 12-by-4-inch size. While perfect for smaller patches, taping, and detail work, it is not the most efficient for large, flat wall areas. Professionals may want a wider trowel (e.g., 14x6) for broader coverage. Additionally, the premium construction comes at a higher price point compared to entry-level carbon steel trowels. For most DIYers and pros, though, the performance and comfort justify the cost.
Based on product specifications and user feedback, the Goldblatt RED finishing trowel is a worthy investment for anyone serious about drywall finishing or plastering. It delivers a comfortable grip, precise control, and a smooth finish while reducing fatigue. Whether you are a contractor, a mason, or a homeowner tackling a basement remodel, this trowel will help you get the job done right without fighting your tools.
Frequently Asked Questions about Trowel Size for 12×24 Tile
What is the best notch size for 12×24 porcelain tiles?
A 1/2-inch by 1/2-inch square notch trowel is the standard recommendation for 12×24 porcelain tiles. This size provides enough mortar coverage to support the large format without excessive squeeze-out. If your subfloor is very flat, a 3/8-inch notch can work, but 1/2 inch is safer for longevity.
Can I use a 1/4-inch trowel for 12×24 tiles?
No. A 1/4-inch trowel is too small for 12×24 tiles. You won’t get enough mortar coverage, leading to voids and potential tile breakage. Stick to a 1/2-inch or at least 3/8-inch square notch for these large tiles.
Should I back butter 12×24 tiles when using a 1/2-inch trowel?
Yes, back buttering is recommended for 12×24 tiles even with the right trowel. A thin skim coat on the tile back ensures 100% coverage and a stronger bond. This is especially important for dense porcelain and natural stone.
Do I need a different trowel for floor vs wall 12×24 tiles?
The same 1/2-inch square notch trowel works for both floors and walls if the substrate is smooth. For walls, you might prefer a lighter trowel like the Goldblatt RED with magnesium shank to reduce fatigue. For floors with slight unevenness, a 3/4-inch notch can help level things out.
How do I check if my mortar coverage is enough for 12×24 tiles?
Lift a tile after setting it and check the back. You want at least 80-95% coverage, with no large voids. The ridges from a 1/2-inch notch should collapse evenly when you press the tile. If you see bare spots, adjust your trowel angle or switch to a larger notch.
What trowel size works for 12×24 tile on a concrete slab?
On a smooth concrete slab, a 1/2-inch square notch is perfect. For rough or uneven concrete, go up to a 3/4-inch notch to ensure enough mortar fills the low spots. Check out our guide on trowel sizes for 4×4 tiles for a comparison on smaller formats.
