Meta description: Designing a small bathroom? Use these tested layouts and styling tricks that work in real Kiwi homes.

Small bathrooms can be surprisingly difficult to design. Every centimetre matters—and when done wrong, they can feel cramped, awkward, and outdated.

At Key Interiors, we renovate dozens of compact bathrooms across Auckland every year. Here are our best small bathroom layout ideas NZ homeowners are using, along with smart styling tips and before/after inspiration that actually works.

🔹 Top Small Bathroom Layouts for NZ Homes

Whether you’re working with a 3m² powder room or a 6m² family bathroom, these proven layouts maximise space, flow, and functionality.

1. The Wall-to-Wall Layout (Shower, Toilet, Vanity)

✔ Great for bathrooms under 4m²
✔ Ideal for long, narrow rooms

Layout:

  • Walk-in shower at the back

  • Wall-hung toilet in the centre

  • Compact vanity near the door

Clean lines and a single wet zone keep it feeling open.

2. Corner Shower with Floating Vanity

✔ Works in square rooms around 5m²
✔ Popular in older villas and bungalows

Layout:

  • Corner shower with frameless glass

  • Floating vanity along the longest wall

  • Toilet tucked beside or opposite

Floating elements create more visible floor space—key for making small rooms feel larger.

3. Shower-Over-Bath with Recessed Storage

✔ Perfect for family bathrooms
✔ Great when you need a tub but have limited space

Layout:

  • Bath and shower combo along one wall

  • Vanity with recessed mirror cabinet

  • Compact toilet opposite

Recessed niches and mirrored cabinets double your storage without adding bulk.

4. Wet Room Style (Fully Tiled)

✔ Great for ultra-small bathrooms or ensuites
✔ Easy-clean, minimalist vibe

Layout:

  • Fully tiled floor and walls

  • Open shower area with linear drain

  • Wall-hung basin and toilet

A frameless design gives a sleek, uninterrupted feel.

Frequently Asked Questions

What’s the best layout for a small NZ bathroom?
The wall-to-wall layout (shower, toilet, vanity) is the most space-efficient for narrow rooms. Corner showers and floating vanities also work well for tighter spaces.

How small can a bathroom be in NZ?
A full bathroom (with shower, toilet, and vanity) can fit comfortably into 3–4m² with clever planning and the right fixtures.

Can I fit a bath in a small bathroom?
Yes, if you’re open to a shower-over-bath combo. There are compact bath models under 1500mm designed for tight spaces.

What type of tiles make a small bathroom feel bigger?
Large-format matte tiles, laid vertically or in stacked patterns, help open up the room. Use similar tones across walls and floors for flow.

Can I customise my layout with Key Interiors?
Absolutely. We’ll tailor the layout to your space, budget, and style—whether you're renovating a villa, unit, or modern townhouse.
