Why rent your site units from ECOS
We build our units in our own factory and have rented them out ourselves for 25 years; more than 4,000 are on sites across Thailand today. A rental unit is lifted, moved and reinstalled dozens of times, so ours are designed for that from the start, and we handle delivery, installation and collection ourselves.

- Friendly service that understands how Thai sites work
- 4,000+ units

OUR STORY· How we think
Useful first. Chosen second.
We have one job: to be useful to our customers. Things people on site use every day, yet few companies can be trusted to provide — portable toilets, for instance — we take on and do properly, at a price people can afford. That is what “useful” means to us.
Good service alone does not get you chosen. However good it is, if it is expensive, customers decide it is not useful. So for 25 years we have kept delivering good units at low prices: sharpening our skills, building our team, and cutting costs where the customer never sees them — then passing on what we save. Cheap, but never blindly cheap: a company that cannot survive is no use to anyone.
Read how we thinkWELDED ON PURPOSE
Rental units that move often need a welded structure
A rental unit moves site two or three times a year or more, dozens of times over ten years. So we weld the roof and floor bases; the unit keeps its shape after dozens of lifts.
This is not a desk calculation. We assembled units two storeys high, loaded sandbags two and three tonnes at a time and measured the deflection, testing imported houses and the Work House the same way. The result: an imported house is a good house if it stays in one place, but for rental units that move dozens of times the Work House is the better fit. That is why ECOS uses the Work House for rental.

FAQ
Rental rate questions
- How much does it cost to rent a container per month?
- A single-cubicle toilet unit from 1,800 baht per month, a 3×3 m office unit from 3,000 baht and a 3×6 m unit from 4,500 baht, a guard house from 2,500 baht, worker accommodation from 4,000 baht per unit, and a 20 ft storage container 3,500–4,000 baht. The actual rate depends on the model and the rental term — longer contracts get a lower monthly rate.
- Do you rent 40 ft containers?
- No. We rent 20 ft storage containers and insulated prefab units from 3×3 to 3×6 m that can be joined together. For the floor area of a 40 ft container, join two or more 3×6 m office units.
- What is the minimum rental period?
- Rent is charged monthly. Tell us how long you need the unit and we will quote a rate for that term. All worker accommodation models have a 3-month minimum contract, and the contract cannot be cancelled early.
- Does the rate include delivery and installation?
- The monthly rate does not. Delivery and installation are charged by distance to your site and itemised in the quotation. We deliver, install and collect the unit at the end of the contract, nationwide.
- What do I need to prepare on site?
- Level ground firm enough to carry the unit — no foundation needed — access for a truck and crane, and a power connection point. See the site-preparation page for details.
- How many units does ECOS have out on rent?
- More than 4,000 units are out on hire at sites across Thailand right now. We have been in the rental business for 25 years and run everything from a single base in Bang Na, Bangkok, which is how we keep the condition of the fleet and the delivery schedule under one roof.
- Can door or window positions change on a rental unit?
- Yes. Panels, windows and doors slot in between the columns, so we arrange them to suit your site before delivery and replace worn panels one at a time.
- Why do your rental units last so long?
- Their roof and floor bases are welded. Unlike low-cost imported houses (mainly Chinese-made), which are bolted throughout, they resist twisting however often they are moved.
- Can we add space when the crew grows?
- Yes. Work House (WH / WL) joins on both the short end and the long side; P-House on the long 6 m side only. Both can be two storeys.

W-House
W-House Prefabricated Office Container
Our main unit, built specifically for rental — the harshest use there is. A site office gets lifted, moved and reinstalled dozens of times, so it has to be tough and genuinely functional. 18 sqm for a team of four to six; single or two-storey, joinable without limit.
3 × 6 × 2.69 m · 18 m²
Rent from 4,500 THB/month
P-House
P-House Economy Office Container
The same 18 sqm footprint as the W-House at a 2.55 m ceiling height, watertight and well insulated against heat and noise. A unit that has to survive years of rental service loses you money if the material does not last — whatever you saved on it. So on the parts that wear, the grade is not reduced: the steelwork is galvanised sheet.

W-House 3x3
W-House 3x3 Compact Prefabricated Office Container
The same build as the 3 x 6 W-House in every respect — only the size differs. Made for rental: lifted, moved and reinstalled dozens of times. 9 sqm suits a supervisor’s office for one or two people, or a site with no room to spare. Single or two-storey, joinable without limit.

ABOUT ECOS
ECOS (Thailand) Co., Ltd. has been manufacturing and renting prefabricated container units for more than 25 years. We build in our own factory, which means we control the specification, the lead time and the condition of every unit that reaches your site.
What we rent
Our range covers the four things a working site actually needs: somewhere to work, somewhere for the crew to sleep, somewhere to control access, and sanitation. Every unit is insulated, wired, and ready to use the moment it is craned into position — there is no foundation to pour and no build programme to wait for.
Who we work with
Main contractors, factories and industrial estate operators, event organisers, and international companies setting up temporary operations in Thailand. We deliver and install nationwide, and we quote in writing before anything moves.
How renting works
Tell us what you need and where the site is. We come back with a written quotation covering the units, the delivery and the rental period. Once the agreement is signed we schedule delivery and installation, and hand the units over ready for use.
