Storage unit prices in Merrillville, IN

Most Merrillville branches advertise several 10x10 units at once, and the second one costs 30% more than the first at the same address. The $50 headline is the entry price, not the shelf.

The market also holds Griffith, Hammond, Hobart, Munster and Valparaiso.

Cheapest 10x10 in Merrillville: $50 on Broadway, $75 once the introductory rate lapses. The dearest branch, Calumet in Hammond, starts at $169.
Only 7 locations feed this page, so a single branch moves every figure on it further than it would in a bigger market.
That $50 rests on one address. The next cheapest branch, Locust in Valparaiso, wants $84, so a unit gone from the first is a 68% jump rather than a short walk.
Space is cheapest by area in the 10x20, at $0.39 a square foot, and dearest in the 5x5 at $1.44.

Where these numbers come from. 38 advertised prices read from Public Storage's own published listings across 7 locations, last checked 2026-08-12.

Online rate vs regular rate. Every listing publishes two figures. Measured across thousands of observations, the regular rate is 1.5× the online rate at the median, with 88% inside 1% of that and none outside 1.40–1.60×. That is a pricing rule, not a second quote. The online rate is the promotional price for booking on the web; the regular rate is what the unit reverts to. Budget on the regular rate. Comparisons here hold the basis constant, so the gap between locations is real either way.

These are advertised rates for new rentals, not quotes — Public Storage states prices are not guaranteed and they move with availability. Insurance, admin fees and limited-time offers are not included.
