InSinkErator Badger 1 vs Badger 5. Which to Buy?
Quick verdict
Badger 5 models sport 1/2 HP induction motors and dual-stage grinding, offering enhanced performance. Their 7-year warranty backs up this claim. In contrast, the Badger 1 features a 1/3 HP motor with single-stage grinding and sports only a 5-year warranty.
Priced between $80 and $120, the Badger 5 easily outshines its cheaper sibling at $70 to $90, with street prices often topping up by about $20. This higher-spec model more than justifies the extra cost over a decade or so due to superior performance.
Stick with a Badger 1 if you’re in a tiny apartment, cook infrequently, or are renting and looking to keep expenses low.

Badger 5 specs: Clocking in at $20 to $50 more than its counterpart, this InSinkErator model features a half-horsepower induction motor enabling two-stage grinding and includes a seven-year in-home service warranty. The Badger 1 opts for a third-horsepower motor supporting single-stage grinding with a five-year warranty attached. Given the enhanced power and reliability of the Badger 5, it generally represents the wiser choice for most installations. Check these details closely before finalizing your purchase.
One naming note: The Badger 500 sold at Home Depot and the Badger 5XL sold at Lowe’s are identical to the Badger 5. Only the label changes. If you see any of those names, you’re looking at the same product.
The badger 1, who it’s actually for
The Badger 1 is a purpose-built entry unit, not a weak one. At 1/3 HP and 1-stage grinding, it handles typical light-cooking household waste without trouble. The problem is that most US households aren’t light-cooking households.
Where the Badger 1 fits well:
- Studio apartments or 1-person households with 2-3 cooking days per week
- Rental units where the owner wants the lowest unit cost (landlords buying 3-5 units at a time will notice the $30-50 savings per install)
- Replacement installs where cabinet clearance is extremely tight, the existing mount is already a Badger 1. You want same-day pickup from any big-box store
The noise tradeoff: The Badger 1 runs at 80-85 dB, about the level of a running vacuum cleaner. The Badger 5 runs at 75-80 dB, closer to a dishwasher cycle in progress. The 5 dB gap is measurable but not dramatic. In an open kitchen it matters during evening cleanup. In a standalone laundry closet it probably doesn’t.
Drop-in compatibility: Because both models use the 3-bolt Quick Lock mount, you can swap a Badger 1 for a Badger 5 without touching the sink flange. The Badger 5 is approximately 1-2 inches deeper than the Badger 1, so measure the clearance under your sink before ordering.

The badger 5, why it wins for most homes
The Badger 5 is the better choice for any household cooking daily. The math is straightforward.
The HP advantage: Going from 1/3 HP to 1/2 HP is a 50% increase in motor power. Both motors run at 1725 RPM (induction motors). But the Badger 5 delivers more torque at that speed. In practice, the Badger 1 will hesitate or jam on harder scraps (small chicken bones, dense vegetable chunks) that the Badger 5 handles with one pass.
The 2-stage grind: Food passes through grinding rings twice in the Badger 5 vs once in the Badger 1. This produces finer particles, which reduces drain clogging over time. Be honest about limits though: neither the Badger 1 nor the Badger 5 handles fibrous foods well. Celery, corn husks, and asparagus wrap around the grind rings in both models. That’s a budget-disposal limitation, not a Badger 1 flaw.
The warranty math: InSinkErator’s in-home service warranty means they send a technician to your home. A single plumber service call runs $100-200. We calculate that the Badger 5’s extra 2 years of coverage costs $30-50 at purchase. Avoiding one service call more than pays for that difference over a 10-12 year lifespan.
Which should you buy?
Use our garbage disposal HP size guide if you want the full sizing framework. For the Badger decision specifically, this table covers most scenarios.
| Household | Cooking Frequency | Recommended | Reason |
|---|---|---|---|
| 1 person / studio apartment | Light (2-3x/week) | Badger 1 | Handles load. Saves $30-50 upfront |
| 1-2 person apartment | Moderate (daily) | Badger 5 | Warranty uplift worth $30 over 7+ years |
| 3-4 person household | Moderate-heavy | Badger 5 | Extra HP handles daily volume reliably |
| 4+ person household, heavy cooking | Heavy | Consider Evolution | Badger 5 is the floor; Evolution 3/4 HP is the next step |
| Rental unit owner | N/A | Badger 1 | Lowest unit cost. Tenants use it lightly |
Emergency same-day replacement: If your disposal just failed and you need a same-day fix, the Badger 1 is stocked at every Home Depot, Lowe’s, and ACE Hardware. It fits the same 3-bolt mount with no flange changes. Buy the Badger 5 if you can wait a day for Amazon delivery.
If clearance is tight: Measure the vertical space under your sink before ordering the Badger 5. It runs 1-2 inches deeper than the Badger 1. When in doubt, check the spec sheet on InSinkErator’s website before you order. If you’re replacing rather than upgrading, our garbage disposal replacement guide covers measurements and what to do with the old unit.
For Energy Star appliance ratings{:target=“_blank”} and efficiency context across kitchen appliances, note that standard garbage disposals aren’t Energy Star rated, but choosing a right-sized motor (not oversized for your household) is the practical efficiency consideration. InSinkErator holds roughly 70% of the US residential disposal market, so parts, service, and compatibility information is widely available for both models.
FAQ
What is the difference between the Badger 1 and Badger 5?
The InSinkErator Badger 5 features a robust 1/2 HP induction motor for dual-stage grinding, paired with a 7-year in-home service warranty, whereas the Badger 1 opts for a less powerful 1/3 HP motor and a shorter 5-year warranty. Retailers typically mark up the Badger 5 by $20 to $50 over its simpler counterpart. Frequent cooks will find the enhanced capacity and extended protection of the Badger 5 well worth the additional expense, as it ensures smoother operation for years.
Can I replace a Badger 1 with a Badger 5?
Yes. Both the Badger 1 and Badger 5 use InSinkErator’s 3-bolt Quick Lock mount, so swapping one for the other requires no sink flange changes. The Badger 5 is approximately 1-2 inches deeper, so verify clearance under the sink before ordering. If clearance is fine, the swap takes 15-30 minutes with a 1/4-inch Allen wrench and basic pliers.
Is the Badger 5 or Badger 500 the same thing?
Yes. The Badger 500 sold at Home Depot and the Badger 5XL sold at Lowe’s are identical to the Badger 5. Only the name label changes for retail channel reasons. All three share the same 1/2 HP motor, 2-stage grinding, 7-year warranty, and 3-bolt Quick Lock mount.
How long does the InSinkErator Badger series last?
InSinkErator’s Badger series grinders typically operate between 10 to 12 years with regular use. Maintenance matters greatly; overly fibrous foods like celery, corn husks, and pasta along with greasy items and starchy peels of veggies or larger bones can shorten lifespan. The Badger 1 and 5 models come with in-home service warranties for 5 and 7 years respectively, meaning repairs are free within those durations if a fault arises.
Is the Badger 5 worth the extra money?
Yes, for households cooking daily. The 7-year in-home service warranty vs 5-year alone justifies the $30-50 difference over the unit’s expected 10-12 year lifespan. One avoided service call ($100-200 for a plumber) more than covers the price gap. For 1-2 person apartments with light cooking, the Badger 1 is a reasonable choice where saving $30 matters.
