Choosing the right size bathroom vanity is one of the most critical decisions in any bathroom renovation. A vanity that's too large will make your bathroom feel cramped and impede traffic flow, while one that's too small may lack adequate storage and look out of proportion. This comprehensive guide will walk you through everything you need to know about sizing a bathroom vanity for Australian homes, from measuring your space to understanding standard dimensions and clearance requirements.
Understanding Standard Australian Vanity Sizes
Australian bathroom vanities typically come in standard widths that increment by 150mm, making it easier to find a size that fits most bathroom configurations. Understanding these standard sizes will help you narrow down your options and ensure compatibility with Australian plumbing standards.
Common Width Options
- 450mm - 600mm: Ideal for powder rooms, small ensuites, and corner installations. These compact vanities prioritise space efficiency over storage capacity.
- 750mm - 900mm: The most popular size range for standard Australian bathrooms. These vanities offer a good balance of storage and counter space for single-user bathrooms.
- 1000mm - 1200mm: Perfect for main bathrooms and larger ensuites. These provide generous storage and may accommodate a larger basin or additional counter space.
- 1500mm - 1800mm: Designed for double basin configurations in master bathrooms. These vanities are ideal for couples who need simultaneous access to the basin.
When choosing between sizes, it's generally better to go slightly smaller than to squeeze in a larger vanity. A bathroom with adequate circulation space always feels more comfortable than one that's cramped.
Standard Height and Depth
While width varies significantly, height and depth are more standardised. Most Australian vanities follow these conventions:
- Height: 850mm to 900mm (including basin and benchtop) is standard. This matches kitchen bench height and is comfortable for most adults. Wall-hung vanities can be adjusted during installation to suit your preferred height.
- Depth: 450mm to 550mm is typical for most vanities. Compact or slimline vanities may be as shallow as 350mm, which is useful for narrow bathrooms or hallway ensuites.
How to Measure Your Bathroom Space
Before shopping for a vanity, you need accurate measurements of your bathroom. Taking the time to measure properly will save you from costly mistakes and returns. Here's how to do it right.
Step-by-Step Measuring Guide
- Clear the area: Remove any existing vanity, towels, or items that might obstruct your measurements.
- Measure the available width: Measure the wall space where your vanity will sit, from wall to wall or between any permanent fixtures like the toilet or shower.
- Check for obstructions: Note the position of doors, windows, towel rails, power points, and any other fixtures that might affect vanity placement.
- Measure plumbing locations: Record the position of water supply lines and waste pipes. Moving plumbing is expensive, so try to choose a vanity that aligns with existing connections.
- Consider door swing: If your bathroom door opens inward, ensure your vanity won't interfere with its operation.
Key Measurements to Record
- Total wall width available for vanity
- Distance from side walls to plumbing rough-ins
- Height from floor to any windows or mirrors
- Door swing clearance required
- Distance to toilet or shower for clearance
Essential Clearance Requirements
Australian building codes and practical considerations dictate minimum clearances around bathroom fixtures. Following these guidelines ensures your bathroom is both compliant and comfortable to use.
Minimum Clearances to Maintain
- In front of vanity: Allow at least 600mm clearance between the vanity front and any opposite wall or fixture. This provides comfortable standing room when using the basin. For wheelchair accessibility, 1200mm is recommended.
- Between vanity and toilet: Maintain a minimum of 150mm between the vanity and toilet. This allows comfortable access to both fixtures and makes cleaning easier.
- Between vanity and shower/bath: A clearance of 50mm minimum is required, though 100mm is preferable for ease of cleaning and to prevent water damage.
- Door clearance: Ensure bathroom doors can open fully without hitting the vanity. Consider door swing direction when planning layout.
These are minimum clearances. Whenever possible, exceed these measurements for a more comfortable bathroom experience. Building regulations may vary by state, so check with your local council for specific requirements.
Choosing the Right Size for Your Bathroom Type
Powder Rooms (Under 3m²)
Powder rooms or half-baths typically only contain a toilet and basin, so space is at a premium. Look for compact wall-hung vanities in the 450mm to 600mm range. Corner vanities are particularly effective in tiny powder rooms, making use of otherwise wasted space. Consider a slimline depth of 350mm to 400mm to maximise floor space.
Standard Ensuites (3m² - 5m²)
Most Australian ensuites fall into this category and can accommodate vanities from 600mm to 900mm wide. Consider a wall-hung vanity to create the illusion of more floor space. A 750mm vanity is often the sweet spot for ensuites, providing adequate storage without overwhelming the room.
Main Bathrooms (5m² - 8m²)
Standard family bathrooms have more flexibility. Vanities from 900mm to 1200mm work well in most configurations. If your household shares this bathroom, consider a wider vanity with ample counter space for multiple toiletries. This is also where double-drawer configurations become practical for family storage needs.
Master Bathrooms (Over 8m²)
Larger master bathrooms can accommodate statement pieces from 1200mm to 1800mm. Double basin vanities are popular choices, allowing couples to use the bathroom simultaneously. In spacious master bathrooms, you might also consider a freestanding vanity positioned away from walls for a luxurious furniture-like appearance.
Final Sizing Considerations
Beyond the raw measurements, consider these practical factors when finalising your vanity size:
- Storage needs: Larger families or those with extensive bathroom products may prioritise a bigger vanity for storage capacity.
- Future resale: Standard sizes are easier to replace and more appealing to potential buyers.
- Proportions: Your vanity should look proportional to your bathroom. A good rule of thumb is that the vanity width should be no more than two-thirds of the wall it's positioned against.
- Installation access: Ensure your chosen vanity can physically fit through doorways and hallways to reach the bathroom.
When in doubt, bring a tape measure when shopping and verify dimensions in person. Online measurements occasionally differ from actual products, and the difference between 895mm and 900mm could affect your installation.
Taking the time to properly size your bathroom vanity will result in a more functional and aesthetically pleasing bathroom. Remember to measure twice, account for clearances, and consider your household's specific needs when making your selection.
