What Should You Check Before Choosing a Capsule House Manufacturer?

Selecting the right Capsule House Manufacturer is as important as selecting the design when you are looking to buy a capsule house for a resort, glamping site, hotel, vacation rental or a private project. A beautiful model is nothing if the factory cannot ensure quality, provide the necessary documents, or help you post-sale.

The most critical factors to consider when deciding on a Capsule House Manufacturer are factory capacity, materials and structure, quality control, certifications, real project evidence, total cost, shipping, installation, warranty, and after-sales support.

Read on to find out what questions to ask, what paperwork to demand, and what red flags to watch for when searching for another supplier.

1. Verify the Manufacturer and Factory Capability

Confirm Who Actually Manufactures the Capsule House

How can you be sure that a supplier actually makes capsule houses? Inquire about the company's own production and ask them to demonstrate their production facility and clarify what they do in-house and what they do not, and ask for recent evidence from the factory.

Some suppliers produce their own capsule houses; others predominantly deal with products of various factories. This distinction can impact customization, quality control, lead times and after-sales support.

Before ordering, inquire:

• Is the company the owner or operator of the production facility?
• In which country is the factory located?
• Which production processes are carried out in-house?
• Is the structural frame fabricated in the factory?
• Is the factory responsible for the interior assembly?
• Does the company have current production?

These are questions that a good supplier should be able to answer clearly.

Also request forgenuine factory photos and videos. Find production workers, machinery, welding areas, assembly stations, finished units, storage areas, and loading operations.

A video call can help boost your confidence even more. Request a visit to the factory instead of viewing marketing photos.

Check the Factory’s Production Capability

Why is production capacity important? The factory must have sufficient equipment, personnel, space and production experience to provide your order on a consistent basis.

Review the production line, equipment, current projects, and approximate monthly capacity. If you require 20 or 50 capsule houses, ensure that the manufacturer can do that without long delays.

For instance, mature modular manufacturers may have their company information, including their manufacturing bases, equipment, project history, and manufacturing capacity. Some manufacturers also explain quality-control systems from fabrication to final delivery.

• Expert Tip: Factory size is not necessarily a good indicator of factory capability. A small factory with good engineering, clear processes, and good project experience may be better for your project than a large factory that can't meet your specifications.

2. Check Materials, Structure, and Product Options

Understand the Main Materials and Structure

What are the things to look for when considering a capsule house? Begin with the structural frame, exterior cladding, insulation, roof, flooring, windows, glass, waterproofing, and electrical.

Avoid a quotation that states, “high quality materials.” Request the details.

For instance, ask for details on:

Component	What to Check
Structural Frame	Steel type, dimensions, coating, welding process
Exterior	Cladding material, thickness, weather resistance
Walls	Panel type, thickness, insulation
Roof	Construction, waterproofing, insulation
Flooring	Material, thickness, moisture resistance
Glass	Type, thickness, safety performance
Windows	Frame material, glazing, sealing
Electrical	Electric, plugs, switches, lights
Plumbing	Pipes, fittings, water connections

It's worth paying particular attention to the structure, since the capsule house has to deal with transportation, installation, wind, weather, and normal use.

The glass and sealing system should also be carefully examined. Panoramic windows are sometimes a significant portion of a capsule house; therefore, inquire about the manufacturer's control of water leakage, air sealing, drainage, and installation tolerances.

If you are installing electrical systems, your manufacturer should be familiar with the needs of the country where you're installing the system. For example, IEC 60364 deals with the design, installation and verification of low-voltage electrical installations, such as prefabricated buildings and transportable units.

Compare Models and Customization Options

Is it possible for a Capsule House Manufacturer to customize the design? Most manufacturers provide customization but check the details of what can be modified before entering into a contract.

Ask about:

• Overall dimensions
• Floor plans
• Bedroom layouts
• Bathroom layouts
• Window positions
• Door locations
• Furniture
• Kitchen equipment
• Bathroom fixtures
• Lighting
• Exterior finishes
• Interior finishes
• Electrical configuration

For instance, a capsule house could be used for a mountain resort that requires a large panoramic window and a small bathroom. For a glamping project, another buyer might require multiple units that are all the same in terms of furniture and layout.

Don't assume that changing is free. Have the manufacturer break down the quote into standard, optional, and custom items.

3. Review Quality Control and Certifications

Check the Quality Control Process

How do you know the quality of the manufacturing before the capsule house gets to you? Inquire at the factory about its quality-control system from raw materials to final inspection.

A good process will include structural fabrication, welding, assembly, waterproofing, electrical and interior installation, and inspection.

Inquire about the manufacturer's testing:

• Incoming materials
• Structural dimensions
• Welding quality
• Surface treatment
• Insulation installation
• Installation of windows and glass.
• Waterproofing
• Electrical connections
• Plumbing
• Final appearance and function:

Some modular manufacturers detail their quality systems, which include material inspection, welding qualifications, coating checks, and other production controls.

Inspection records, photos, or a third-party pre-shipment inspection can also be requested prior to the factory loading your units.

• Expert tip: Don't take a manufacturer's assurance that it “checks everything” at face value. Inquire about what it checks, how often it checks, and what records it maintains.

Review Certifications and Technical Documents

Will certifications guarantee that a capsule house will comply with local building codes? No. Do not assume that a factory certificate or general product certificate automatically means the final building complies with all the rules in the destination market.

Ask for:

• Company certifications
• Product test reports
• Material certificates
• Technical specifications
• Structural drawings
• Electrical diagrams
• Installation manuals
• Warranty documents
• Export documentation

While ISO 9001 can be a helpful sign of a quality management system, it should not be considered as a license for your particular building project. In a similar way, the CE requirements vary according to the product and the relevant European legislation, and the CE marking does not necessarily replace local building approval requirements.

This is important because capsule houses are real buildings once they are installed on a site. Your local authority might ask for structural calculations, electrical compliance, fire performance, energy requirements, planning approval, or other documents.

Please consult the building code of the country and local authority of the country where you intend to install the capsule house before ordering.

4. Look for Real Production and Project Evidence

Ask for Recent Production Evidence

What evidence is required of a manufacturer? Request recent images and videos of actual production, not just final promo shots.

Request:

• Current production photos
• Structural frame photos
• Interior assembly photos
• Finished-unit photos
• Packaging photos
• Loading photos
• Container-loading videos

When possible, request images from your actual production batch from the manufacturer.

This is done to assist you in understanding the product you ordered with the actual product that the factory produces.

If the quote is for a specific type of glass, flooring package, bathroom package, and furniture package, request production photos that demonstrate these elements.

Review Completed Projects

Why is it important to go through finished projects? Real projects are the best way to see if the manufacturer can provide a product that will perform outside the showroom.

Inquire about project information like

• Project type
• Number of units
• Installation country
• Delivery date
• Product model
• Installation method
• Client references (if any)

A manufacturer who has done project work abroad will know more about export packaging, documentation, logistics and installation than a factory that has no experience of overseas deliveries.

A few modular factories say they have projects in several countries overseas and offer case studies to prove their manufacturing and delivery capabilities.

It's not necessary to have hundreds of projects. You have to have the appropriate projects that fit your product and market.

5. Compare Quotations, Shipping, and Installation

Compare the Full Product Configuration

What should you look at when comparing the prices of capsule houses? Look at full specs, not just the unit price.

The prices quoted by two manufacturers can vary widely depending on the materials, equipment, warranty, and installation services included. It's not always the cheapest that is the best.

Compare manufacturers by product specification, factory capability, customization options, production capacity, warranty and delivery services before making a decision. The following is an example of how GLAMNI can be compared to two other well-known capsule house manufacturers based on the same criteria.

Make one comparison sheet such as this one:

Comparison Item	GLAMNI	JYD House	CGCH
Manufacturer Type	Capsule house manufacturer	Modular/capsule house manufacturer	Space capsule & modular building manufacturer
Production Facility	Large-scale factory facilities in Anhui, China	Factory in Foshan, Guangdong, China	Multiple production facilities

The information above is based on information made available by each manufacturer. Product specifications, production capacity, warranty conditions, and services may differ from model to model and project to project; please check the latest information directly with the respective suppliers before ordering.

When you compare the whole product configuration, you will be able to understand the difference in price. One supplier may even provide a lower price but not include furniture, air conditioning, high quality glass, transportation, or installation.

Confirm Shipping and Installation Arrangements

Does the capsule house quotation include shipping and installation? Don't assume that it does. Have the manufacturer clearly distinguish the factory price, shipping cost, destination charges, and installation cost.

Also confirm:

• Packaging method
• Loading method
• Container requirements
• Shipping terms
• Estimated production time
• Estimated transit time
• Unloading requirements
• Crane requirements
• Foundation requirements
• Installation team
• Installation manual
• Technical support

Some modular manufacturers provide a service to take care of design, production, shipping, installation, and after-sales support, while others just provide the manufactured unit.

Installation support can be a huge asset for a remote resort. Even if the factory has constructed a fine capsule house, your project can still have trouble if no one takes the time to show you how to prepare the foundation, how to set the house in place, how to connect utilities, or how to finish the house.

6. Check Warranty, After-Sales Support, and Warning Signs

Understand the Warranty and Support

What should be included in a capsule house warranty? Request a warranty in writing that specifies what parts are covered, how long the warranty lasts, what is not covered, and how to file a claim.

Don't take a vague assurance, like “we offer long-term support.”

Ask:

• What is the length of the structural warranty?
• Which of the following is a warranty for electrical components?
• What is plumbing covered under?
• What type of warranty do windows and glass come with?
• What is the consequence of a component failing?
• Is the manufacturer able to provide spares?
• Who pays for shipping of replacement parts?
• What does the manufacturer do in case of technical issues?

Some modular manufacturers list different warranties for structural, electrical, and finishing components, which is an indication of why it is important to ask for component-level warranties rather than a single, catch-all warranty.

Watch for Common Warning Signs

What are the largest red flags to look out for when selecting a Capsule House Manufacturer? Don't deal with suppliers who cannot demonstrate their factory capability, do not have clear specifications, who cannot verify certificates, or who do not explain what is included in their quotation.

Be alert for the following red flags:

• No actual factory data
• Only stock photos
• Refusal to show production
• Unclear material specifications
• Certificates with unverifiable information
• When there is significant discrepancy between photos and quotation
• Very low prices and no specification.
• No written warranty
• No shipping plan is evident.
• No installation instructions
• Time pressure to pay promptly.

It is not a rule that the lowest price is the worst supplier. But you need to know the reason for the low price.

One supplier might quote on the capsule shell alone, for instance, while another might quote on furniture, bathroom hardware, HVAC, high quality glass, packaging, and technical support. The second quotation might seem high, but consider the full package.

7. Quick Capsule House Manufacturer Checklist

Before you select a manufacturer, make sure you can answer “yes” to the important questions below:

• Can the supplier prove that it manufactures the capsule house?
• Is there verification of the factory and production facilities?
• Is the manufacturer able to produce the product in sufficient quantities?
• Have full material and product specifications?
• Are you familiar with the structural system?
• Does the manufacturer allow for customization of your needed design?
• Does the factory describe its quality-control procedure?
• Are the relevant certificates and test reports available?
• Is there recent evidence of production from the manufacturer?
• Does it have some relevant finished projects?
• Is the quote clear, and list all the items?
• Do you have shipping and installation confirmed?
• Have you written a warranty?
• Is the manufacturer able to supply spare parts and technical support?

If a supplier is unable to answer a few of these questions, keep looking until you find the one who can.

FAQs About Capsule House Manufacturer

How can I verify a capsule house manufacturer?

One way to check the credibility of a capsule maker is to check his/her factory, production capacity, business information, certifications, recent production evidence, and finished products. Request a live factory tour and technical documents rather than just a website photo.

What should a manufacturer provide before ordering?

A manufacturer should furnish a detailed quotation, product specifications, drawings, material information, certifications or test reports (where applicable), a production schedule, shipping terms, installation information, and a written warranty.

These documents will provide you with a clear idea of what you'll actually get.

Is buying directly from a capsule house factory better?

When you purchase directly from a factory, you might have more control over the specification, customization, price, and communication; however, if the factory is not capable of producing and exporting, then you do not have control.

Don't select direct factory purchasing just because it appears to be a better price. Look at quality, service, documentation, logistics, and after-sales support as well.

Can a capsule house manufacturer customize the design?

Yes, many capsule house manufacturers do allow some customization, but the options available will vary from factory to factory. Please verify any change in size, layout, window, finishes, furnishings, bathroom fixtures, electrical and exterior design before ordering.

Always inquire if there are any changes in the manufacturing time and/or cost due to customization.

Does a capsule house quotation include shipping and installation?

Not necessarily. There are some suppliers who provide the whole service; others may only quote the factory price.

Request the manufacturer to itemize the product, packaging, shipping, destination, unloading/foundation work, installation, and utility connections.
