Freeing up a packed garage in Anglet, keeping furniture safe during renovation work in Bayonne, decluttering a cellar-free flat in Biarritz: there's never a shortage of reasons to look for a storage unit. And almost every time, the same question comes first. How much does it cost? The honest answer is that there's no single price, only a logic behind it. Here's how to read a self-storage quote, what makes it move, and how to avoid paying for square metres you'll never fill.

What moves the price of a storage unit

Renting a unit is a bit like renting a flat: it comes down to a handful of concrete factors. Once you've got the logic, you compare like with like and steer clear of nasty surprises.

Size: this is factor number one. You rent by usable volume, from a small unit of 1 to 3 m² up to a space that swallows an entire home. The bigger the floor area, the higher the monthly rent, but the price per square metre often drops on the larger formats.
Duration: a few weeks during a move and a long-term need aren't handled the same way. With us there's no commitment: you pay as long as you occupy the space, and you cancel the moment the need ends.
The town and the centre: land costs more along the coast. A unit in central Biarritz isn't the same context as one in Tarnos, along the A63. Shifting a few minutes away often changes the bill.
Access and services: drive-up outdoor access, wide opening hours, a ventilated building under video surveillance with access control. These are part of the value, not just a line on the price sheet.
Insurance: covering what you store adds a small line, but it's real peace of mind for your belongings.

Rather than figures that could be out of date tomorrow, the most reliable habit is to look directly at our up-to-date rates for the centre you have in mind.

Concrete benchmarks, size by size

To picture it, the volume equivalent often speaks louder than the bare price. Here are three tiers and what people in the area typically store in them. The exact amounts depend on the centre and the season: always ask for today's price.

The small unit (1 to 3 m²)

The "extra cupboard" format. You slide in boxes, surf gear, a few flat-packed pieces of furniture, archives, seasonal items. Perfect when you live in a new-build flat in Anglet or Bayonne, with a tiny utility nook and no cellar at all. It's the most affordable tier, starting at a few euros a week depending on the exact size.

The medium unit (4 to 8 m²)

The equivalent of a small room. Enough to clear out a studio or a one-bedroom flat, keep appliances and a bedroom's furniture safe during renovations, or set up a back base for a tradesperson. The most versatile format, and the one many families in transition turn to.

The large unit (10 m² and up)

Here we're talking about the contents of a whole home: a three-bedroom flat, sometimes more. Ideal for a move with mismatched dates, an estate to handle without rushing, or a long absence. The monthly rent climbs, but per cubic metre it's often the best-value tier.

Choosing right, without overpaying

Two mistakes keep coming up: going too big "just in case", or too small to save money and ending up cramming everything in. A few simple habits sidestep both traps.

Take an inventory before you book: list the bulky items (sofa, appliances, bed), estimate the rest in boxes. Our tool to work out your unit size gives you a benchmark in a few clicks.
Think in height: a unit fills up to the ceiling. Stacked well, a more compact format is often enough.
Match the size to how long you'll really need it: for a few weeks, a snug, flexible format beats signing up big "to be safe".
Beware the false savings of the cellar or garage: in the Basque Country, a damp cellar ends up spoiling what it's meant to protect, and a packed garage never turns into usable space.

An example over in Biarritz

Hélène, a nurse in Biarritz, was hesitating over keeping her daughter's belongings in the cellar after she left to study. An old cellar with traces of damp: she was worried about the boxes of books and the furniture. She chose a small ventilated unit in Anglet, about ten minutes away via the BAB, with free parking right outside the door. The result: a manageable rent, belongings kept dry, and a budget far lighter than she'd imagined.

The price depends mostly on size, duration, town and access.
