Bathtub Manufacturing Process in 5 Steps

As we have always emphasized, Giving Tree Home is a comprehensive bathroom brand. We not only collaborate with other brands to offer a wider range of products but also have our own factory to impress every customer with lower prices and innovative designs. Particularly for the bathtub series, some users may want to thoroughly understand the brand before purchasing due to the high cost. An important aspect is understanding our manufacturing process, which is the purpose of this article. We will fully demonstrate how Giving Tree Home completes the production of a bathtub from start to finish, including design, production, and inspection. Let's get started!

Step 1: Starting with Design

Most users browsing the Giving Tree Home bathtub series will marvel: this is not just a bathtub, but a piece of art. This is thanks to our high emphasis on design. Almost all of the bathtubs produced by Giving Tree Home are crafted by two master designers: Luca Veltri and Vicent Clausell.

Luca Veltri hails from Italy, which is renowned as the "Sanctuary of Art." He graduated from the Politecnico di Milano with a bachelor's degree in architecture and urban planning and a Ph.D. in urban and architectural design. Luca has served as an art director for several companies and collaborated with renowned architect Piero Lissoni. Luca's design philosophy centers on unique shapes and smooth lines, achieving a perfect balance between aesthetics and practicality in bathtubs.

Vicent Clausell, one of the founders of Clausell Studio, is a Spanish designer with a bachelor's degree in industrial design and a master's degree in spatial design. He has won numerous international design awards, including the iF Design Award, ADI Compasso d'Oro Award, and European Product Design Award. When designing bathtubs for Giving Tree Home, Vicent focuses on infusing these static objects with more vitality, making them more vivid and expressive.

Step 2: Choosing Materials

There are various materials used in bathtub production, including acrylic, solid surface, stone, cast iron, copper, and fiberglass. Each material has its characteristics and there is no clear superiority. Users looking for cost-effectiveness often choose fiberglass bathtubs, while those who prefer retro designs might consider cast iron or copper bathtubs. Giving Tree Home primarily uses acrylic and solid surface materials for bathtub manufacturing.

Acrylic is a popular bathtub material that achieves the best balance with its affordable price, excellent quality, and attractive appearance. Solid surface materials, on the other hand, are a newer premium composite material. Although expensive, their reparability is unmatched; minor scratches can be easily fixed with simple sanding, keeping the bathtub in perfect condition.

Step 3: Constructing the Body

In recent years, the update and iteration speed of bathtub styles have significantly accelerated, not only due to improved living standards but also due to the widespread application of thermoforming foam technology in bathtub manufacturing. This technology is primarily used in the production of acrylic bathtubs. Using quickly formed molds, it shortens production cycles and significantly reduces production costs.

During the manufacturing process, pre-cut acrylic sheets are heated and softened, then vacuum-formed and pressed into molds. Once cooled, the acrylic sheet forms the same shape as the mold. Bathtubs produced with this process usually have a hollow structure, with the hollow layer around forming a natural insulation layer. However, the hollow bottom structure can cause reliability issues, particularly when the bathtub is filled with water and weight is added, potentially collapsing due to gravity. To address this, Giving Tree Home pre-makes a high-quality resin mixture to reinforce the framework and bottom of acrylic bathtubs before manufacturing.

Unlike vacuum forming, solid surface bathtubs are molded by injection. During manufacturing, the material is mixed to a molten state, then directly poured into molds. Once fully cooled and solidified, it is removed from the mold. This injection molding process makes solid surface bathtubs solid in structure, heavier in weight, and uses more material, contributing to their higher cost.

Step 4: Detailed Processing

After the initial forming steps, the bathtub's main contour is basically formed, but fine detailing is necessary to achieve perfect appearance and functionality. First, the excess edges are trimmed, then the entire bathtub is meticulously polished to ensure a smooth surface.

Next, necessary holes are drilled at designated positions, including the drain and overflow holes. For some bathtubs with separate inner and outer tubs (mainly acrylic bathtubs), these parts need to be connected and fixed with specific glue and tools to ensure firmness and reliability.

Step 5: Final Inspection

This is what sets Giving Tree Home apart and is a primary reason why customers choose us. To ensure the quality of our bathtubs, we conduct meticulous inspections on every bathtub produced. These inspections include appearance checks, water leakage tests, load tests, durability tests, insulation tests, and chemical resistance tests.

During the testing process, any defects require rework to ensure each bathtub meets our high standards. Through these stringent quality control measures, we guarantee that every bathtub received by customers can last at least 15 years.
