How Are Toilets Made? Full Checklist for Buyers

2. How Are Toilets Made? A Step-by-Step Look Inside the Manufacturing Process

Toilets are everyday essentials, yet few people know the precision and craftsmanship involved in their creation. At Cleanman, a 23-year-old ceramic toilet factory, we combine traditional ceramic techniques with modern smart technology to build toilets that are durable, efficient, and eco-friendly.

In this article, we walk you through the complete toilet production process—from the raw clay to the final boxed product—based on actual factory procedures used at Cleanman’s facilities. Alternatively, you can watch the video if you don’t want to read so many steps.

2.1 Product Design

The process starts at the design table. Specifically, engineers and designers work together to ensure the toilet’s shape supports:

• Efficient flushing
• Comfortable ergonomics
• Aesthetic harmony with modern bathrooms

Designs are modeled in 3D software. Subsequently, they are tested for water flow, splash reduction, and space optimization.

2.2 Mold Making

Once the design is finalized, custom molds are produced. In fact, these molds will shape the toilet during casting.

Mold Prep Steps:

• First, clean the mold, wiping the slip side with slurry.
• Second, apply talcum powder to double-sided slip zones to avoid sticking.
• Finally, assemble the mold for the slip-casting process.

2.3 Slip Formulation and Preparation

Toilets are made primarily from vitreous china—a mixture of clay, feldspar, quartz, and water.

At Cleanman, we follow a strict sequence:

• Initially, the slip is filtered with fine sand.
• Next, a sand pump ensures no air bubbles enter.
• Finally, the slip is filled into molds until full. As a result, no empty slip areas are allowed.

☑️ This step is critical to avoid micro-cracks and weak spots.

2.4 Working Mold and Slip Casting

In this stage:

• First, we pour the slip into the mold until it forms a consistent 1.0mm wall thickness.
• Next, technicians carefully check the thickness at the injection hole to ensure precision.
• Finally, we drain the excess slip and return it to the tank for future use.

Once the slip forms a hardened shell, we proceed as follows: Remove the mold panel; Patch cracks; Furthermore, drill inlet and outlet water holes; Ensure no slurry sticks to internal surfaces.

2.5 Trimming and Initial Assembly

After moderate drying, the body is flipped. Meanwhile: Cracks and leaks are patched; The foot mold is opened and reinstalled; Moreover, the outlet base is fixed to the bottom. This phase requires skilled hands to ensure structural integrity.

2.6 Drying and Assembly

The toilet is completely demolded, trimmed, and patched. Following this:

• Remove casting lines
• Apply slurry to the tank mouth
• Reinstall the tank for the second round of drying

The body is placed on a drying rack. In addition, cracked areas are wrapped with paper and cloth. Lastly, drill the tank base to level the slurry.

2.7 Inspection

Before glazing, Cleanman conducts thickness checks, crack inspections, and sand hole drilling. Moreover, we perform surface smoothing and qualification marking. Because of this rigor, only flawless units move forward.

2.8 Glazing

The body is coated in a glassy white glaze to seal the ceramic, add smoothness, and prevent staining. Key steps include trimming final lines and applying slurry/clay caps. Finally, we perform pre-drying in a special room.

2.9 Loading into kilns

Glazed toilets are loaded into kilns on trays. Importantly, Cleanman uses smart tracking for product traceability from the kiln to the warehouse.

2.10 Kiln Firing

Toilets are fired at ~1270°C for strength and durability. Notably, proper temps prevent blue smoke, ensuring a perfect white finish.

2.11 Post-Firing Inspection

After cooling, our workers unload and stack ceramics on trays. Therefore, only certified, flawless products pass to packaging.

2.12 Packaging and Storage

At Cleanman, we water-test, dry, clean, pack and store each unit. Additionally, we use eco-friendly recyclable packaging.

3. FAQs

1) Why are toilets usually white?

White represents cleanliness and is easier to inspect for hygiene. Furthermore, the color reflects the natural hue of porcelain glaze. However, we also provide matt color toilets. Indeed, it is already a very mature technology.

2) Can we recycle toilets?

Yes! We can break down old toilets and reuse them as roadbed material or construction aggregate.

3) What is vitreous china?

Vitreous china is a robust ceramic material. Specifically, technicians glaze and fire it at high temperatures to ensure perfect durability and water resistance.

4) How long does it take to make a toilet?

With a ready mold, it typically takes 14 days from casting to finished toilet. In contrast, for OEM orders, it takes about 40 days.
