What Impacts the Cost of a Bathroom Renovation?

There are a few major cost factors to consider:

  • Size of the bathroom: Larger rooms require more labour and materials.

  • Finishes and tiles: Full tiling, natural stone, and premium fixtures increase cost.

  • Plumbing changes: Moving your shower or toilet adds cost due to new pipework.

  • Layout redesigns: Knocking down walls or repositioning elements increases complexity.

  • Custom cabinetry or mirrors: Going custom adds visual impact, but also adds cost.

Real Cost Examples from Key Interiors Projects

Here’s how we’ve helped real Auckland clients get the bathroom they wanted — at different budgets:

  • Under $20K: Basic upgrades like new vanity, partial tiling, paint, tapware. Ideal for rentals or resale.

  • $25K–$35K: Full retiling, quality fittings, LED mirror, wall-hung vanity, fresh lighting.

  • $40K+: Custom layout, premium brushed brass tapware, walk-in tiled shower with niche and frameless glass, full tile walls and floors.

You can see examples of these styles on our Projects Page.

Tips for Renovating Without Overspending

  • Retain the existing plumbing layout to avoid major labour costs

  • Focus on one or two premium features instead of everything

  • Use cost-effective cabinetry options with a luxury finish

  • Limit tile coverage to key areas (like behind the vanity or inside the shower)

Is a Bathroom Renovation Worth It?

Absolutely — especially if you’re selling. Along with kitchens, bathrooms are one of the most important rooms when it comes to buyer perception and resale value. A stylish, modern bathroom makes a huge difference. We cover this more in our blog:
