Otti Laguna Mark II 750mm Black Oak Wall Hung Vanity

1. Measure your space

Measure wall width, floor depth and door swings, and note where existing plumbing sits. Make sure there is enough room to stand at the vanity, open drawers and doors fully, and move through the bathroom without squeezing past.​

2. Choose your vanity size

• 465mm – 600mm: Best for powder rooms, narrow ensuites or very small bathrooms.​
• 750mm – 900mm: Works well for most standard and guest bathrooms, giving a bit more storage and bench space.​
• 1200mm – 1800mm: Suits shared or family bathrooms and master ensuites, with generous storage and the option for double basins.​

3. Pick an installation style

• Wall-hung: Creates a floating look, makes the room feel bigger and keeps floors easier to clean, but needs solid wall support and earlier planning for plumbing.​
• Freestanding: Sits on the floor, is easier to retrofit with existing plumbing and usually offers more internal storage.​
• Curved fronts: Reduce sharp corners and improve flow in tight or
  high-traffic spaces, especially for families.​

4. Select your colour and finish

• White: Safe, versatile and light-reflecting; ideal for small or low-light bathrooms.​
• Black: Strong contrast and modern feel; better in larger or design-led spaces.​
• Timber: Adds warmth and texture, softens hard finishes and works across coastal, Hamptons and contemporary looks.​

Pro tip: Always check your vanity against floor tiles, wall colour and benchtop so the palette feels cohesive rather than busy.​

5. Plan for basins, taps and storage

Decide if you need a single or double basin based on how many people use the bathroom at a time. Style your vanity with complementary basins, mixer taps, robe hooks, towel rails and storage like shaving cabinets or mirrors so everything works together day to day.​

6. Set your budget

Plan to spend roughly 10–15% of your total bathroom budget on the vanity, which for many homes might fall in the $800–$3,000+ range once size, finish and storage are factored in. Decide if you want to pay extra for wall-hung installation or premium finishes.​
