If you’re a renter or just dipping your toe into the soft-water pool, a portable unit is your buddy. These countertop or spin-on models cost between $50 and $200. Think of them as the training wheels of water softening—they work okay, but they won’t save your whole house from the calcium apocalypse.
You’ll need to refill them with salt, which is like feeding a very picky hamster. They handle one faucet, usually your kitchen sink. So your dishes will sparkle, but your shower will still leave you feeling like a chalk statue.

This is the beast you picture when you hear “water softener.” It’s a big tank, a little tank, and a lot of salt. For a standard two- or three-bedroom home, expect to pay between $500 and $2,500 for the unit itself. Installation can add another $300 to $600, unless you’re a plumbing wizard or have a very forgiving neighbor.
Here’s the funny thing: you’re basically buying a robot that eats salt and spits out soft water. It’s like a Rumba for your pipes, but it costs as much as a used moped. The ongoing salt cost? About $5 to $10 a month—less than your coffee habit, but more annoying because you have to haul 40-pound bags from the store.
