• Packaging
• Custom requirements

For businesses selling bathroom products under their own brand, OEM manufacturing provides more control over product differentiation.

Typical OEM bathtub services include:

• Custom bathtub dimensions
• Customized shapes
• Different installation structures
• Surface finish options
• Brand labeling
• Packaging customization
• Project-specific specifications

The goal of OEM manufacturing is not simply producing more units.

The goal is creating a repeatable bathtub product that matches the buyer's market requirements.
