Self storage in Spain: complete guide to types, prices and how to choose

A storage unit (trastero in Spanish) is an individual, enclosed and secure storage space rented on a monthly basis to store furniture, boxes, seasonal clothing or other personal belongings. In Spain, the self storage sector has more than 700 facilities and generates over 300 million euros in annual revenue. The average rented size is 3 m² and the average contract duration is 8 months.

Types of storage units in Spain

There are three main storage models in the Spanish market. Each has a different operation, price point and service level.

Traditional self storage

The customer rents a unit (room, box or metal cage) inside a storage facility. The customer handles transport, loading and space organization. Access is in-person during facility hours. Operators such as Bluespace (over 50 locations), Shurgard, Homebox and City Self Storage run this model in Spain. Prices start at 35-50 EUR/month for a 1 m² space in Madrid or Barcelona.

Door-to-door storage

A service where the company picks up items at the customer's address, packs them professionally, stores them in warehouses with 24/7 surveillance and delivers them back on demand. The customer never visits a facility. Box2Box operates this model in Spain with service in Madrid, Barcelona, Valencia, Seville and Malaga. Prices start at 41 EUR/month (first month from 20.50 EUR with -50% promo).

Furniture storage (guardamuebles)

A guardamuebles is a larger storage space (typically from 5 m²) where complete household furniture and belongings are deposited, usually during moves or renovations. Some moving companies offer furniture storage as an add-on service. Prices range from 100 to 400 EUR/month depending on volume and city.

How much does a storage unit cost?

Storage unit prices in Spain depend on the city, size and service model. These are the updated 2026 market references:

*Current promo: 1st month at -50% on the monthly plan (minimum stay 3 months), 2 months on the biannual plan, 5 months on the annual plan. Free pickup for 1-3 m² spaces. No lock-in period. Promo subject to change.

At traditional centers, add transport costs (50-150 EUR per trip), packing materials (30-60 EUR) and deposit (1-2 months rent) to the monthly price. With Box2Box, pickup is free for 1-3 m² spaces and there is no deposit.

How does door-to-door storage work?

Door-to-door storage is completed in 4 steps without the customer traveling anywhere:

1. Request pickup online

The customer requests a quote via the website, WhatsApp or phone in under 2 minutes and indicates what to store. No commitment.

2. Professional pickup at your door

A professional team arrives at the customer's address, wraps each item with proper protection and loads it onto the vehicle. Free for spaces of 1 to 3 m².

3. Secure storage with digital inventory

Items are stored in warehouses with 24/7 surveillance and insurance included from day one. Each item is photographed and logged in a digital inventory accessible via the app.

4. Delivery to your door in 24-48 hours

When the customer needs something, they request it from the app and receive full or partial delivery (specific items) at their door within 24-48 hours.

Box2Box operates this model in 5 Spanish cities with an average rating of 4.9/5 across more than 2,500 Google reviews.

How to choose a storage unit

Choosing the right storage unit requires evaluating four factors before signing up.

Size needed — For boxes and seasonal clothing, 1 m² is enough (equivalent to 10-15 boxes). For a full bedroom with furniture, you need 3 m². For a full apartment move, between 5 and 10 m². Box2Box allows you to change size at any time without penalty.

Location or service — A traditional facility requires you to travel every time you need something. With door-to-door storage, the warehouse location does not matter because the service comes to your home. If you need frequent in-person access, choose a nearby facility. If you access a few times per month, the doorstep model saves time and transport costs.

Security — Check that the facility has 24/7 surveillance, individual access control and contents insurance. At traditional centers, insurance is usually optional (10-20 EUR/month extra). With Box2Box, insurance is included in the price.

Real cost — Compare total cost, not just the monthly fee. Add transport, packing, deposit and insurance. A storage unit at 40 EUR/month with 150 EUR transport and 2 months deposit costs 310 EUR the first month. A door-to-door unit at 41 EUR/month with everything included costs 41 EUR the first month (20.50 EUR with the -50% promo).
