When planning a bathroom design, be you are a hotel or real estate developer, renovation contractor or bathroom product brand, determining the appropriate depth of a ceramic bathroom sink is always a critical decision. The sink depth impacts not only the user experience and washing efficiency, but also the cleaning efficiency, installation methods, appearance, and product cost.
In this post, we’ll weigh the pros and cons of deep sinks with shallow sinks and answer the age-old question, “How deep should a wash basin be?” – so you can pick the best ceramic sink for your project.
Key Differences Between Deep vs Shallow Ceramic Bathroom Sinks
Deep Ceramic Bathroom Sinks — Greater Practicality
Deep sinks are typically 18–22 cm deep (or deeper) and have the following characteristics:
- Better splash resistance: Water is less likely to splash out, suitable for high-frequency use scenarios such as hotels and public spaces.
- Suitable for large bathroom countertops: Deep sinks blend more harmoniously in larger bathrooms.
- Can hold more water: More suitable for multi-functional scenarios such as washing face, hair, and items.
- More “Present”: Visually stable and with a strong sense of quality.
- Suitable scenarios: Hotel rooms, high-end residences, commercial renovations, public restrooms.
Shallow Ceramic Bathroom Sinks — Lighter and More Modern
Shallow sinks are typically 11–16 cm deep and have the following advantages:
- Modern, slim visual effect: Ideal for minimalist or modern style bathrooms.
- Convenient for children and the elderly: No need for deep bending, more ergonomic.
- Saves countertop space: Visually lighter, fits well even in small bathrooms.
- Easy to clean and drains quickly: Shallow basins are generally simpler in design.
- Suitable scenarios: Small apartments, condominiums, budget-friendly projects, and youthful home styles.
Deep vs Shallow: How to choose based on space layout and purpose?
- Based on usage scenario
- Deep basins are more suitable for frequently used spaces with multi-functional needs (such as hotels).
- Shallow basins are more suitable for families, rental apartments, or homes that prioritize design.
- Based on countertop size
- Countertop ≥ 500 mm: Suitable for deep basins.
- Countertop ≤ 450 mm: Shallow basins are more harmonious.
- Based on budget and installation method
- Countertop basins can be either deep or shallow, with visual style having a greater impact.
- Undermount and recessed basins are typically deeper and more practical.
- Wall-mounted basins are more commonly shallow, saving space.
- Based on Ease of Maintenance and Cleaning
Shallow basins are easier to clean, while deeper basins offer a cleaner and more efficient cleaning experience.
What Should Be the Depth of a Wash Basin?
From an ergonomic and user experience perspective, the optimal depth for ceramic bathroom sinks is generally:
- Daily Home Use: 15–20 cm
- Hotel/Commercial Spaces: 18–22 cm
- Children’s Use: 11–14 cm
Why is this depth range optimal?
✔ Deep enough to prevent splashing
✔ Comfortable and effortless to use
✔ Suitable for most countertop structures
✔ Compatible with various faucet heights
If you are doing bulk purchasing or OEM customization, adjustments can also be made based on the project’s target audience, installation method, and design style.
