Selecting the size of a bathroom vanity requires considering the bathroom's area, the users' heights, and the spatial layout. Key standards include:
Choosing Width Based on Bathroom Area
- Ultra-small bathrooms (1–3 m²): Opt for mini models (55–70 cm wide); in extreme cases, choose a narrow 40 cm version with a reduced depth of 40–45 cm. Wall-mounted units are preferred to avoid obstructing the walkway.
- Standard bathrooms (3–5 m²): Choose an 80–100 cm linear single-basin vanity. The vanity width should occupy 50%–60% of the total bathroom width, ensuring the countertop accommodates standard toiletries.
- Large bathrooms (>5 m²) or multi-person households: Select a 120–150 cm double-basin model. This ensures two people can wash up simultaneously with 60 cm of workspace each, preventing elbows from bumping.
Determining Countertop Height Based on User Height
- General standard: Countertop height of 80–85 cm from the floor suits most adults, eliminating the need to bend over excessively.
- Customization formula: Calculate using "(Height ÷ 2) + 5 cm." If the family's average height exceeds 160 cm, the height can be raised to 90 cm; if elderly people or children are present, the height can be lowered appropriately.
- Installation differences: Floor-standing units have a total height of 80–90 cm, while wall-mounted cabinet bodies are about 55 cm high; however, the final installed countertop height must still fall within the 80–85 cm range.
Managing Depth and Complementary Details
- Standard cabinet depth is 45–55 cm; depths under 40 cm make bottled toiletries prone to tipping over. Ensure sufficient clearance: the distance from the basin to the shower area should be at least 60 cm, and the distance to the edge of the toilet at least 80 cm.
- The mirror cabinet should be about 10 cm shorter than the main vanity and 12–15 cm deep. Leave a gap of over 30 cm between the bottom of the mirror cabinet and the countertop to avoid head bumps, and position the top 1.85–2 m from the floor for comfortable viewing.
- Take precise measurements three times beforehand, keeping the margin of error within 1 cm. Avoid interfering with hot/cold water pipes or drain outlets, and leave a 10 cm ventilation gap behind the cabinet.
