Here are a few modifications for the water pan of the Weber Smokey Mountain Cooker.

To learn more about the purpose of the water pan and variations when using it, see Using A Water Pan In The WSM.

WSM water pan vs. Brinkman charcoal pan

Increasing Pan Capacity

Dave Stamper writes to TVWB, "I have been smoking with water smokers for over 35 years. I have built some and also purchased some, but the WSM is the best small cooker out there, in my opinion.

"The biggest fault I can find with this cooker is the rinky-dink water pan. Why own a smoker that is capable of running unattended for 10-12 hours on one fill of charcoal if it wasn't for the lousy water pan?"

Dave's solution is to replace the WSM water pan with a Brinkmann charcoal pan. It holds almost 2 gallons of water, twice the capacity of the WSM pan.

Picture 1 shows the WSM water pan next to the Brinkmann charcoal pan. Pictures 2 and 3 show the difference between the Brinkmann and WSM pans inside the middle cooking section. Picture 4 shows how the pan's wide rim sits firmly on the water pan support flanges.

Here are the specs comparing the two pans:

Brinkmann Pan WSM Pan
Outside diameter at rim 15-1/16" 14-3/4"
Inside diameter, top of pan 12-7/8" 14"
Inside diameter, bottom of pan * 8-1/2" N/A
Width of rim 1-1/16" 5/16"
Depth 4-1/2" 3-1/16"
Distance between bottom of pan and top of charcoal ring 3-1/4" 5-1/4"
Water capacity Almost 2 gallons 1 gallon
Weight 1 lb, 4.3 oz 1 lb, 9.7 oz
* The inside of the Brinkmann pan curves down to a flat bottom, while the WSM pan has a rounded bottom.

Dave says, "It's a drop-in modification and actually fits better than the standard pan. It cuts down on the room between the bottom of the pan and the charcoal, but works fine under all conditions that I have tried.

"I find that a fellow gets two benefits from this larger water pan. First, instead of checking and adding water every two to three hours depending on cooking temperature, I can run my cooker over nine hours with this pan before adding water. The second benefit--and this is the best one--is that this larger water pan really helps control the temperature in the smoker. I think all folks that use this cooker know that as the water goes down in the pan, the temperature goes up in the smoker. I find that I can just about run any temperature I want from 180°F to about 250°F real easy without making many adjustments."

I have purchased one of these pans and it works quite well. The wide rim does provide a more stable fit for the pan when placed in the middle cooking section.

  • The Brinkmann Charcoal Pan, part number 114-0002-0, can be ordered from Brinkmann at 800-468-5252 or from the Brinkmann Web site.
  • This pan is also available at retailers that carry Brinkmann smokers, and is sometimes sold under part number 812-0002-0.
  • The price ranges from $4 to $14 depending on where you purchase the pan.

Extended water pan flange

Extended Water Pan Flanges

Some people complain that the water pan is not stable when placed on the support flanges. Albert Sanchez writes, "I had the unique opportunity to somehow bump the WSM water pan, causing it to completely fall off the bracket flanges into the charcoal ring. Splashed water everywhere, steam mushroom cloud, partially doused my charcoal, etc."

Albert's solution was to extend three of the four flanges by attaching 1-1/4" x 3/4" x 1/8" steel strips using stainless steel screws and nuts.
