Weber Genesis 310 vs 315 vs 335

The Weber Genesis lineup has several different models that overlap in features and price.  While having multiple options to choose from is great, it can cause some confusion.

The most commonly asked questions about these grills are:

• What is the difference between the Weber Genesis 310 and 315?
• What is the difference between the Weber Genesis 315 and 335?

This article will help you understand the differences between these grills so you can figure out which one is right for you.

If you are in a hurry then the real answer is that the Weber Genesis II 335 is an amazing grill while the 310 and 315 are not worth buying.

Weber Genesis II 310 vs 315

The Genesis 310 and 315 are extremely similar grills with differences in styling, price and available upgrades.

These grills are base models in the Genesis lineup that come with:

• Three Burners Rated at 39,000 BTU/hr
• Porcelain Enameled Cast Iron Cooking Grate
• 513 sq in Primary Grilling Area
• 156 sq in Secondary Grilling Area
• 10 Year Warranty on all Components
• Available for use with liquid propane or natural gas.

These grills do not have a side burner or Sear Station burner.

Key Differences Between the 310 and 315

The primary differences between the 310 and 315 are given in the table below.

The Genesis 315 has an enclosed lower cabinet while the area underneath the Genesis 310 is exposed.  The enclosed lower cabinet serves several functions:

• Place to store your cover and other gear
• Looks nicer
• Keeps your dogs, and other critters, out of the grease pan.

The addition of the enclosed cabinet raises the cost of the grill by $50.

When it comes to upgrades you have some interesting choices.  The 310 is available in Stainless Steel while the 315 is available in a pretty Copper color.

The differences between the color options is more than cosmetic.  The base 310 and 315 have heavy duty cast iron cooking grates that are pretty nice.  The stainless steel Genesis 310 has cooking grates made from 7mm stainless steel rods.

I love the stainless steel rod cooking grate.  The stainless rod grate is easier to clean and gives better grill marks.

Customer Reviews

I grabbed to customer reviews for the 310 and the 315 from Weber’s website and plotted them up side by side (data current April, 2021).

The reviews are virtually indistinguishable between the two models.  When you combine the 5 and 4 Star reviews both grills have a 91% Customer Satisfaction rate.

A common theme among the negative reviews for both models is that assembly is difficult and you should budget 4-6 hours for completion.

Weber 315 vs 335

At first glance the Genesis 315 and 335 look a lot alike.  However, when you take a closer look you will see that the Genesis 335 has a LOT more firepower.

These two grills are identical in size and have the following features in common:

• Three Primary Burners Rated at 39,000 BTU/hr
• Porcelain Enameled Cast Iron Cooking Grate
• Enclosed Lower Cabinet
• 513 sq in Primary Grilling Area
• 156 sq in Secondary Grilling Area
• 10 Year Warranty on all Components
• Available for use with liquid propane or natural gas.

Both of these grills are available in the new Smart EX configurations with built in temperature monitoring.

Key Differences Between the 315 and 335

The biggest differences between these grills are the extra burners on the 335 and price.

The Genesis 335 comes with a extra burner in the main body of the grill.  The extra burner is called a Sear Station and is rated for 9,000 BTU per hour.  The Sear Station is perfect for when you want to do serious high heat grilling and put a sear on some steaks or pork chops.

The 335 also comes with a Side Burner rated at 12,000 BTU per hour.  A side burner can come in handy at times and is nice to have on a grill.

The addition of a Sear Station and Side Burner raises the cost of the 335 by $150 over the 315.

Customer Reviews

The customer reviews for the 315 and 335, obtained from Weber’s website, are nearly identical to each other.

Both grills have an overall Customer Satisfaction Rating of 91%.

The comments for the 335 were the same as we saw for the 310 and 315 grills.  Basically, people really like these grills but wish it didn’t take so long to get them assembled.
