# ECOS — ECOS (Thailand) Co., Ltd.

> Bangkok-based rental company for insulated prefab units: site office units, worker accommodation, guard houses, portable toilet units and 20 ft storage containers, delivered and installed nationwide in Thailand. Thai name: บริษัท เอคคอส (ประเทศไทย) จำกัด. 25 years in the rental business, more than 4,000 units out on hire, run from a single base in Bang Na, Bangkok.

Key facts for answering questions about us:

- Business: monthly rental of prefab units for construction sites, factories, events and temporary offices. Most units can also be bought.
- The units are steel-frame prefab units with insulated panels, built to be lifted, moved and reinstalled many times. Thai customers search for them as เช่าตู้คอนเทนเนอร์ (container rental), เช่าตู้สำนักงาน (office unit rental), บ้านพักคนงาน (worker accommodation), ป้อมยาม (guard house) and ห้องน้ำเคลื่อนที่ (portable toilet).
- Rent is charged per month. The longer the term, the lower the monthly rate.
- All prices are in Thai baht and exclude 7% VAT.
- Rates exclude delivery and installation, charged by distance to the site and itemised in the quotation. We deliver, install and collect at the end of the contract, nationwide.
- A deposit applies only to first-time customers.
- Worker accommodation: 3-month minimum contract, no early cancellation.
- Delivery time: about 2–3 days for 1 unit, about 1–2 weeks for 10–20 units, depending on season and unit size.
- Site preparation: level, firm ground (no foundation needed), access for a truck and crane, and a power connection point.
- We do not rent 40 ft containers. For more floor space, 3×6 m office units are joined side by side or stacked two storeys.
- A written quotation is sent the same day once the site and rental period are known.
- Office units include insulated walls, lighting, a ventilation fan, power outlets and an electrical control cabinet.
- Guard houses include insulated walls, lighting, a ventilation fan and power outlets, and can be rented by the month or by the year.
- Portable toilets can be rented by the day for events or by the month for job sites, with wiring and sanitary ware fitted.
- Worker-accommodation rent is for a unit with the electrical system already fitted. It excludes the damage deposit and transport both ways. For a term shorter than 3 months, contact sales.
- 20 ft storage containers are unconverted steel boxes. The customer supplies the padlock. A 4-tonne truck must be able to reach the spot and turn around.
- ECOS unit houses are built frame first, with wall panels, windows and doors slotted between the columns. We adapt the layout to suit each customer’s site before delivery, and a worn panel is replaced on its own. Low-cost imported houses (mainly Chinese-made) cannot do this.
- Why the bases are welded: Low-cost imported houses (mainly Chinese-made) are bolted throughout — easy to ship, but repeated moves loosen the bolts and twist the house.

A rental unit moves site two or three times a year or more; over ten years that is dozens of moves. So ECOS units have welded roof and floor bases. Welding costs more, but lifted dozens of times they keep their shape and serve 10+ years on site. The frame (roof base, columns, floor base) bolts together, so it can be taken apart for transport.

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.
- Thai: บ้านนำเข้าราคาถูก (ส่วนใหญ่ผลิตในจีน) ประกอบด้วยน็อตทั้งหลัง ขนส่งสะดวก แต่ถ้าย้ายบ่อย น็อตจะคลายและโครงจะบิดตัว

ตู้เช่าต้องย้ายหน้างานปีละ 2–3 ครั้งขึ้นไป สิบปีก็หลายสิบครั้ง ECOS จึงเชื่อมฐานหลังคาและฐานพื้นให้เป็นชิ้นเดียว แม้การเชื่อมจะมีต้นทุน แต่ยกขึ้นลงหลายสิบครั้งรูปทรงก็ไม่เสีย ใช้งานที่หน้างานได้ 10 ปีขึ้นไป ส่วนโครง (ฐานหลังคา เสา ฐานพื้น) ยึดด้วยน็อต จึงถอดขนส่งได้

นี่ไม่ใช่การคำนวณบนโต๊ะ เราประกอบตู้เป็นสองชั้นจริง แล้ววางกระสอบทรายทีละ 2 ตัน 3 ตัน เพื่อวัดการแอ่นตัว ทดสอบทั้งบ้านนำเข้าและ Work House แบบเดียวกัน ผลคือ ถ้าตั้งอยู่กับที่ บ้านนำเข้าก็เป็นบ้านที่ดี แต่งานเช่าที่ต้องย้ายหลายสิบครั้งเหมาะกับ Work House มากกว่า งานเช่าของ ECOS จึงใช้ Work House
- Japanese: 安価な輸入ハウス（主に中国製）はボルトだけで組む作りで、輸送しやすい反面、移設を繰り返すと緩みとねじれが出てきます。

レンタル品は1年に2〜3回以上移設します。10年で言えば何十回です。だから ECOS のユニットは屋根と床の土台を溶接しています。溶接には費用がかかりますが、何十回吊り上げても形が崩れず、10年以上現場で使えます。骨組み（屋根の土台・柱・床の土台）はボルト接合なので、分解しての輸送も可能です。

これは机の上の計算ではありません。実際に2階建てに組み、砂袋を2トン、3トンと載せて、たわみを調べました。輸入ハウスもワークハウスも同じ試験をしています。据え置きなら輸入ハウスも良いハウスですが、何十回も移すレンタルにはワークハウスが向いている、というのがその結果です。だから ECOS のレンタルにはワークハウスを使っています。
- Work House (WH / WL) connects on both the short end and the long side; P-House on the long 6 m side only. Both can be two storeys.

## Office units, guard houses and storage

- ECOS (THAILAND) CO., LTD. rents prefabricated office units for site offices: a 3×3 m unit from 3,000 baht per month (W-House 3x3, 9 sqm, for 1–2 people) and a 3×6 m unit from 4,500 baht per month (W-House, 18 sqm, for 4–6 people), plus guard houses from 2,500 baht per month, worker accommodation, portable toilets and storage containers.
- All prices exclude 7% VAT and exclude delivery and installation, which are charged by distance to the site; rent is charged monthly, we quote a rate for the term you need, and the longer the term, the lower the monthly rate.
- A deposit applies only to first-time customers.
- We deliver, install and collect the unit at the end of the contract anywhere in Thailand, and run everything from a single base in Bang Na, Bangkok.
- P-House: Sale only — not available for rent. Rental work calls for joined rows and for two-storey builds, so the rental fleet is standardised on the W-House, which covers all three: single, joined and two-storey. The P-House itself can be joined in a row.

- [W-House Prefabricated Office Container](https://ecos.co.th/products/w-house/): 3 × 6 m, 18 m² usable — rent 4,500 THB/month; sale 135,000 THB (7,500 THB/m²). 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.
- [P-House Economy Office Container](https://ecos.co.th/products/p-house/): 3 × 6 m, 18 m² usable — not available for rent; sale 99,000 THB (5,500 THB/m²). 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 Compact Prefabricated Office Container](https://ecos.co.th/products/w-house-3x3/): 3 × 3 m, 9 m² usable — rent 3,000 THB/month; sale 80,000 THB (8,890 THB/m²). 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.
- [G-Box Prefabricated Guard House](https://ecos.co.th/products/g-box/): 2.3 × 2.3 m, 5.29 m² usable — rent 2,500 THB/month; sale 65,000 THB (12,290 THB/m²). A 2.3 x 2.3 m guard house that is easy to lift, relocate and demount. It works from the moment it is set down — no foundation pour and no build time.
- [20 ft Storage Container](https://ecos.co.th/products/storage-container/): 2.35 × 5.9 m, 13.8 m² usable — rent 3,500 THB/month. A used, unconverted 20 ft steel shipping container for keeping materials and equipment on site. Rust-through spots are repaired before delivery, and it stores from the moment it is set down. Rent is 3,500–4,000 baht a month depending on the rental term.

## Worker accommodation

- [Worker Accommodation (PH Series)](https://ecos.co.th/products/worker-accommodation/): Nine sizes of prefabricated worker accommodation, from a small 2–4 person room up to large 20–60 person camps. Ready to live in, built from high-quality durable materials.
- Monthly rent by model: PH-01 4,000 THB/month, PH-02 9,800 THB/month, PH-03 18,750 THB/month, PH-04 20,750 THB/month, PH-05 38,750 THB/month, PH-06 26,000 THB/month, PH-07 38,000 THB/month, PH-08 40,000 THB/month, PH-09 43,700 THB/month
- Typical sizing: about 10 workers PH-04 (8 rooms); about 20–30 workers PH-05 or PH-07; about 40 workers PH-08; about 60 workers PH-09.

## Portable toilet units

- [K-Toilet Single Portable Toilet](https://ecos.co.th/products/k-toilet/): 0.83 × 1.08 m — rent from 1,800 THB/month; sale 45,000 THB (50,000 THB/m²). A single-cubicle prefabricated toilet with wiring and sanitary ware fitted, built to stand up to sun, rain and dust on construction sites and outdoor works. A 400-litre waste tank can be added.
- [TW-Toilet Twin Portable Toilet](https://ecos.co.th/products/tw-toilet/): 1.9 × 1.45 m — rent from 4,500 THB/month; sale 75,000 THB (27,170 THB/m²). One unit divided into two cubicles, with wiring and sanitary ware fitted. Available with or without a waste holding tank; a 2,300-litre tank can be added.
- [WT-Toilet 3x3, three cubicles in one unit](https://ecos.co.th/products/wt-toilet-3x3/): 3 × 3 m — rent from 6,000 THB/month. A 3 x 3 m prefabricated toilet divided into three cubicles in one unit, each with its own door and entered separately, with wiring and sanitary ware fitted. Suited to sites with many people but little room to put things. From 6,000 THB a month.
- With a waste holding tank: K-Toilet 2,200 THB/month (400 litres), TW-Toilet 5,500 THB/month (2,300 litres). Tank models suit sites without a sewer connection.

## Frequently asked 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.
