  September 18, 2025

Renovating a bathroom is a significant investment. Although the cost depends on several factors, it can be cheap if you are looking for a small renovation. Project size, material and fixture selection, labour costs, and electrical and plumbing costs are the main factors behind your bathroom renovation cost. However, you can avoid overpaying by using smart tactics.

 

Do you want to give your old, boring bathroom space a fresh look? It is actually a great idea to enhance your bathroom’s appearance with tile work and fixture upgrades. But how much does it take to complete? To be honest, there is no exact answer. There are a few factors that affect the cost of your bathroom renovation in Auckland.

Before you head to a bathroom renovation contractor, let’s understand the factors that influence the cost of your project.

The Average Bathroom Renovation Cost in Auckland

The average bathroom renovation cost can be different for specific bathroom renovation types, such as:

  • Basic/Budget Renovation: Costs can start from around $9,000 to $26,000, involving minor cosmetic updates like new fixtures, basic tiling, and paint, without changing the layout.
  • Mid-Range Renovation: This type of project typically costs between $29,000 and $40,000, including mid-range materials, some layout adjustments, and upgraded fixtures.
  • High-End/Luxury Renovation: Actually, there is no limitation. Expect to pay $53,000 and upwards for a custom design. The cost increases with premium materials, designer fixtures, custom cabinetry, and potentially structural changes, creating a spa-like experience.

Exploring the Factors That Influence Your Bathroom Renovation Project

  • Size and Scope of the Project: One of the biggest factors that affects your renovation cost is the size and scope of your project. While a minor cosmetic update is much cheaper, a huge transformation adds some extra cost to your budget.
  • Material and Fixture Selection: If you want to take your bathroom renovation to the next level, you must update the floor materials and fixtures with the latest and premium options. This can also add some cost to your overall renovation project.
  • Plumbing and Electrical Work: If your existing plumbing and electrical work is not suitable for the desired bathroom renovation results, then you have to hire electricians and a plumber to make changes, leading to increased budget.
  • Professional Service and Labour Cost: Last but not least, you have to consider the professional service cost. If you have a short timeline and the project size is large, then you have to pay more to get your desired results.

Tips to Manage Your Budget

  • Plan and Prioritize: Make a list of your essentials versus desired choices to help you make smart choices and avoid overspending.
  • Get Multiple Quotes: Contact several contractors to compare costs and ensure you are getting fair prices and quality service.
  • Keep the Existing Layout: Avoiding layout changes and keeping plumbing fixtures in their original locations is one of the most effective ways to save money.
  • Consider a Phased Approach: If you can't afford a full remodel at once, consider tackling the project in smaller, more affordable stages.
