Weber stands as the undisputed leader in outdoor BBQ grills and smokers with over 70 years of experience. The Weber Smokey Mountain Cooker, affectionately known as the “Weber Bullet” or “WSM,” first appeared in 1981 and has since become the gold standard for backyard smoking. This iconic water smoker continues to win barbecue competitions and the hearts of pitmasters worldwide, available in three sizes to fit every need and budget.

What Makes the Weber Smokey Mountain Different From Other Smokers
The WSM belongs to a category called “water smokers” or “bullet smokers” due to its distinctive vertical, bullet-shaped design. Unlike horizontal offset smokers or drum smokers, the WSM uses a water pan between the fire and the food. This design creates exceptionally stable temperatures and adds moisture to the cooking environment, two factors that separate good barbecue from great barbecue.
The Three-Part Design That Makes Temperature Control Simple
The WSM consists of three main sections that stack together:
- Fire Bowl (Bottom Section) – Houses the charcoal ring where charcoal briquettes and smoke wood reside. Three adjustable aluminum dampers on this section control airflow and therefore temperature.
- Cooking Section (Middle) – Contains the porcelain-enameled water pan and two cooking grates stacked vertically. An aluminum access door allows you to add fuel without disturbing your cook.
- Domed Lid (Top) – Features a built-in thermometer with a smoke-zone indicator marking the 200-275°F sweet spot, plus a silicone grommet for digital thermometer probes. One damper on top completes the airflow control system.
The Smoking Process From Start to Finish
Most WSM users employ the “minion method” for long cooks. You fill the charcoal ring with unlit briquettes, add a small amount of lit charcoal on top, and let the fire slowly spread through the unlit fuel over 8-12+ hours. Fill the water pan, place your food on the grates, adjust the dampers to your target temperature, and the WSM maintains steady heat with minimal intervention. The water pan acts as a heat sink that moderates temperature swings and adds humidity, keeping meat moist throughout the cook.
Three Weber Smokey Mountain Models and Which One Fits Your Needs
Weber offers the Smokey Mountain Cooker in 14-inch, 18-inch, and 22-inch sizes. Each serves a different purpose, and understanding the differences helps you avoid buying too small (frustrating) or too large (wasteful). All three share the same fundamental design and quality, differing primarily in cooking capacity and fuel consumption.
| Specification | 14-Inch WSM | 18-Inch WSM | 22-Inch WSM |
|---|---|---|---|
| MSRP Price | $289 | $419 | $549 |
| Total Cooking Area | 286 sq in | 481 sq in | 726 sq in |
| Dimensions (H x W x D) | 31.4″ x 14.7″ x 14.7″ | 41″ x 19″ x 21″ | 48.5″ x 23″ x 24″ |
| Best For | 1-4 people, travel, limited space | 4-8 people, most popular choice | 10-30 people, parties, competitions |
| Capacity Examples | 2 pork butts or 3-4 rib racks | 4 pork butts or 8 rib racks | 6+ pork butts or 12 rib racks |
| Weber Model Number | 711001 | 721001 | 731001 |
The 18-Inch Model Works Best for Most Home Pitmasters
The 18-inch WSM hits the sweet spot for most home users. It handles 2 briskets or 4 pork butts with ease, uses charcoal efficiently, and maintains temperatures more predictably than the larger 22-inch model. Unless you regularly cook for crowds of 15+ people or compete in barbecue competitions, the 18-inch provides all the capacity you need without wasting fuel.
The 14-inch works well for solo cooks, couples, small families, or anyone with limited patio space. Keep in mind that full spare ribs may need trimming or rolling to fit, and a full packer brisket requires some maneuvering. The 22-inch excels for frequent entertainers, large families, or competition cooks, but note that it can be difficult to stabilize below 275°F and consumes significantly more fuel per cook.
Standard Features Included With Every Weber Smokey Mountain
Weber includes everything you need to start smoking right out of the box. The following features come standard on all three sizes, reflecting Weber’s commitment to quality that has kept the WSM design largely unchanged for over 40 years.
- Porcelain-Enameled Construction – The lid, bowl, and center section resist rust, cracking, and peeling while retaining heat exceptionally well

Turn Your WSM Into a Smart Smoker With the Weber Connect Hub
The WSM works seamlessly with modern smart grilling technology. While the smoker itself has no electronics, you can add wireless temperature monitoring that transforms overnight cooks from anxious babysitting sessions into relaxed, phone-monitored events.
Weber Connect Smart Grilling Hub Features and Compatibility
The Weber Connect Smart Grilling Hub connects via WiFi and Bluetooth to your smartphone. Insert the probes through the WSM’s silicone grommet, and the app delivers real-time temperature monitoring, flip and serve notifications, food readiness countdowns, and step-by-step cooking guidance. The hub supports up to four probes simultaneously, letting you monitor multiple pieces of meat and the ambient smoker temperature from anywhere with an internet connection.
Why Pitmasters Choose the Weber Smokey Mountain Over Other Smokers
The WSM has earned its reputation through decades of proven performance. Competition teams regularly win using stock or lightly modified WSMs against smokers costing five times as much. Here’s what makes it stand out.

Common WSM Issues and How Experienced Users Solve Them
No smoker achieves perfection, and the WSM has a few well-documented quirks. Fortunately, the active user community has developed solutions for each one, and aftermarket accessories address the most common complaints.
The Aluminum Door Leaks Smoke and Heat
The most frequent complaint involves the flimsy aluminum access door that doesn’t seal tightly. Smoke visibly escapes around the edges, and the door can warp over time. Many users bend the door slightly for a better fit as a free fix. For a permanent solution, aftermarket gasket kits (around $20-30) seal the door completely. This issue affects temperature control more than flavor, as some smoke leakage is normal in any charcoal smoker.
The 22-Inch Model Struggles to Hold Low Temperatures
Owners of the largest WSM frequently report difficulty stabilizing temperatures below 250-275°F, even with dampers nearly closed. The larger volume requires more airflow, making true low-and-slow cooking (around 225°F) challenging without modifications. Users often run an 18-inch charcoal ring in the 22-inch model, use less fuel, or accept slightly higher cooking temperatures. This rarely affects the 14-inch or 18-inch models.
No Hinged Lid Means Removing It Completely Each Time
Unlike kamado-style smokers with hinged lids, the WSM lid lifts off entirely. During long cooks requiring spritzing or mopping, finding a safe place for the hot lid becomes inconvenient. Aftermarket hinge kits ($25-40) add this functionality, allowing one-handed lid operation.
The 14-Inch Model Has Limited Space for Large Cuts
Full spare ribs (which can span 15-18 inches before trimming) won’t fit flat on the 14-inch grates. Users either trim to St. Louis style, cut racks in half, or use a rib rack to stand them vertically. Full packer briskets require trimming or creative positioning. The 18-inch model eliminates most of these constraints.
The Most Popular WSM Modifications and Accessories
A thriving aftermarket exists for WSM upgrades. While the smoker works excellently out of the box, these modifications address known issues and add convenience features. All products listed below are available on Amazon.
LavaLock Gasket Kit Seals the Door and Lid
Approximately $20-30. This kit includes Nomex gasket material and high-temperature RTV adhesive to seal the door and lid. Installation takes about 30 minutes and dramatically reduces smoke leakage. Most experienced WSM users consider this the single best modification for new owners. Fits all three WSM sizes.
Lid Hinge Kits Add One-Handed Lid Operation
Multiple brands offer hinge kits ($25-40) that allow the lid to open and stay in a locked position. No more searching for a safe spot to set a 400°F lid during spritzing sessions. Installation requires drilling a few holes and basic tools. Available from Hunsaker, LavaLock, and others on Amazon.
Automatic Temperature Controllers Eliminate Overnight Monitoring
Digital temperature controllers ($150-250) connect to one of the bottom dampers and automatically adjust airflow to maintain your target temperature. Products like the FireBoard Drive, ThermoWorks Billows, and BBQ Guru allow true “set it and forget it” smoking. Ideal for overnight brisket cooks or competition use where consistent temperatures matter most.
How the Weber Smokey Mountain Compares to Its Main Competitors
The charcoal smoker market offers several alternatives to the WSM. Each design philosophy involves tradeoffs between simplicity, control, versatility, and price. Understanding these differences helps you choose the right tool for how you want to cook.
| Smoker | Price | Type | Best For |
|---|---|---|---|
| Weber Smokey Mountain 18″ | $419 | Water/Bullet | Users who want precise temperature control and authentic smoke flavor with a learning curve |
| Pit Barrel Cooker Classic | $429 | Drum | Users who want simplicity above all else with a fixed-temperature, set-it-and-forget-it design |
| Oklahoma Joe’s Bronco | $355-399 | Drum | Users who want versatility to smoke and grill with adjustable temperature control |
| Oklahoma Joe’s Bronco Pro | $499 | Drum | Competition cooks who need 15+ hour fuel capacity with hinged lid and side shelf |
The Pit Barrel Cooker Prioritizes Simplicity Over Control
The Pit Barrel Cooker uses a single vent that you set once based on your altitude. Meat hangs vertically on hooks, and the smoker runs at a fixed temperature around 275°F with no adjustment needed. This “set it and forget it” approach produces excellent results for ribs, chicken, and pork shoulders, but offers no ability to fine-tune temperature for different cuts. Choose the WSM if you want control; choose the Pit Barrel if you want simplicity.
Oklahoma Joe’s Bronco Adds Grilling Versatility
The Bronco drum smoker converts to a charcoal grill by repositioning the charcoal basket, something the WSM cannot do easily. It won the 2025 Men’s Journal Best Overall Smoker award. The tradeoff is that drum smokers lack the water pan that gives the WSM its exceptional temperature stability and moisture control. Choose the Bronco if you want one cooker for smoking and grilling; choose the WSM for dedicated smoking performance.
Final Verdict on the Weber Smokey Mountain Cooker
The Weber Smokey Mountain Cooker remains the benchmark for backyard charcoal smoking. Its combination of exceptional build quality, precise temperature control, authentic smoke flavor, and competitive pricing makes it the top recommendation for both beginners and experienced pitmasters. The 18-inch model offers the best balance of capacity and usability for most households.
Weber’s 10-year warranty on major components provides confidence that this purchase will last. Add a gasket kit and digital thermometer, and you have a setup capable of producing restaurant-quality barbecue in your own backyard. Whether you smoke your first pork butt or compete at a regional barbecue competition, the WSM delivers consistently outstanding results.
