1. Small Bathrooms (Area under 6 m²)
For smaller bathrooms, it is recommended to choose a built-in or mini bathtub, with a length of 1200mm–1500mm and a width of 700mm–750mm. These types maximize space efficiency while meeting basic bathing needs. Examples include:
• 1200mm × 700mm: Suitable for single-person use; compact and space-saving.
• 1400mm × 750mm: Suitable for small households, balancing comfort with space efficiency.
Additionally, corner or fan-shaped bathtubs are ideal choices for small spaces, as they effectively utilize corner areas.
2. Medium-sized Bathrooms (Area 6–10 m²)
Medium-sized bathrooms can accommodate more comfortable bathtubs; built-in or freestanding models are recommended, with the following size ranges:
• Length: 1500mm–1700mm
• Width: 750mm–800mm
• Depth: 400mm–500mm
A 1700mm-long bathtub is the “gold standard” for medium-sized bathrooms; it fits the physique of most adults and offers a superior soaking experience. If the budget allows, consider a bathtub with basic massage functions to enhance comfort.
3. Large Bathrooms (Area over 10 m²)
For spacious bathrooms, freestanding bathtubs or whirlpool tubs are excellent choices, allowing for larger dimensions:
• Length: 1700mm–2000mm
• Width: 800mm–1000mm
• Height: 550mm–700mm
Large bathtubs are suitable for households with multiple members or users seeking a high-end lifestyle. For instance, an 1800mm × 900mm freestanding bathtub offers ample space, making it perfect for long, relaxing soaks.
4. Considerations for Specific User Groups
• Children: If there are children in the home, it is advisable to choose a shallower bathtub (around 400mm deep) to ensure safe usage. • For the elderly: When selecting a bathtub for seniors, it is advisable to include grab bars or choose a model with a door; a length of 1,500 mm–1,600 mm is recommended to facilitate easy entry and exit.
• For two-person use: If a bathtub for two is required, the width should exceed 1,000 mm, and a length of 1,800 mm–2,000 mm is recommended.
