Overview
InSinkErator and Waste King together own about 90% of the garbage disposal market. They take different approaches -- InSinkErator charges a premium for sound insulation and brand cachet, while Waste King competes on power-per-dollar and uses a different motor technology. Here's how they actually compare when you break down the value.
Cost Breakdown
Pro Tips
- Best value overall: Waste King Legend 3200 (3/4 HP, ~$100, lifetime warranty). It's hard to beat for the price.
- Best for quiet kitchens: InSinkErator Evolution Compact or Excel. The sound insulation premium is real and worth it for open-concept homes.
- If replacing the same brand, stick with it to avoid mounting hardware changes and installation hassle.
- Read the warranty fine print. Waste King's lifetime warranty is transferable; InSinkErator's is not.
Mistakes to Avoid
- Assuming InSinkErator is better because it costs more. At comparable HP, performance is similar for everyday use.
- Choosing Waste King only on price without considering noise in a quiet kitchen.
- Switching brands without realizing the mounting systems are incompatible -- budget for the swap kit or extra installation time.
- Comparing models by HP alone without checking grind chamber material and insulation.
When to Call a Pro
Both brands are equally DIY-friendly for same-brand replacement. If switching brands, a plumber handles the mounting swap in 15-20 extra minutes.
Bottom Line
Waste King wins on pure value -- more power and longer warranties for less money. InSinkErator wins on noise and premium features. For most kitchens, a $100-$150 Waste King Legend is the best deal. For quiet kitchens, spend the extra $100 on InSinkErator's Evolution line.
