You wouldn’t buy a fridge without checking the doorway, right? Same with softeners. They’re bulky beasts—often the size of a small trash can.
Measure your space: height, width, depth. And consider where the brine tank goes (it holds salt). Don’t forget door clearance. One guy bought a unit that didn’t fit in his basement stairwell. He named it “The Monument.”
Pro tip: leave a few inches for airflow. Softeners need to breathe, just like you after a big meal.
