🧠 Where to Spend
1. Waterproofing & Plumbing
Cut corners here and you’ll pay for it later. Always use qualified trades for waterproofing, and ensure plumbing is correctly relocated or capped.
2. Lighting & Ventilation
Good lighting and an effective extraction fan will keep your bathroom mould-free and fresh. Upgrade these early—they make a big difference in how the space feels.
3. Vanity & Storage
A solid vanity with decent storage is essential. Go for soft-close drawers, water-resistant materials, and a style that suits your home long term.
💡 Where to Save
1. Stick to the Existing Layout
Keeping your toilet, shower, and vanity in the same positions saves thousands in plumbing changes.
2. Mix High + Low Finishes
Pair a designer-look vanity with basic white wall tiles. Use premium tapware on an affordable basin. Contrast creates visual interest without a high-end budget.
3. Prefab Shower Units
If you’re not set on tiled showers, prefabricated acrylic or composite units are fast to install, watertight, and easy to clean.
4. Choose Tile Wisely
Go for large-format matte porcelain tiles for the floor and basic white tiles for the walls. They’re affordable, low-maintenance, and still look polished.
🧼 Styling Tricks on a Budget
Use a round or pill-shaped mirror to soften the space
Add matte black or brushed tapware for a modern look
Choose one feature element—like a coloured vanity or fun tile
Use open shelving or hooks instead of full cabinetry where possible
Add layered lighting (mirror light + ceiling LED) to enhance the vibe
You don’t need to spend $50K to get a Pinterest-worthy bathroom.

Frequently Asked Questions
Can I renovate a bathroom for under $20K in Auckland?
Yes—if you keep the existing layout, use prefabricated fixtures, and choose mid-range materials, you can renovate for $18,000–$25,000 in most cases.
What’s the most expensive part of a bathroom renovation?
Plumbing changes, tiled showers, and custom cabinetry usually drive costs up. We recommend splurging only where it adds long-term value.
Is tiling always necessary?
Not always. In small or budget bathrooms, you can use paint-rated wet area walls or acrylic shower liners to save money while still looking sharp.
How can I make a budget bathroom feel high-end?
Use contrast—like matte black tapware on white tiles, or wood-look finishes with clean white walls. Good lighting and a stylish mirror also make a big impact.
