As simple as it sounds, the answer is complex.

At KraftMaster Renovations, we remodel dozens of bathrooms every year, so we’ve seen it all—from compact spaces to sprawling luxury retreats. Let’s dive into the factors that impact the cost of a master bathroom remodel and provide some example scenarios to give you a frame of reference.

What Affects the Cost of a Master Bathroom Remodel?

1. The Size of the Space

Unlike hall bathrooms, which are fairly standardized (typically 5′ x 8′), master bathrooms can vary dramatically in size. These variations influence the fixture count and design complexity.

For instance:

  • Will you have one sink or two?
  • Are you keeping a combined tub/shower or opting for separate spaces?
  • Do you want a statement tub or a simple layout?

A larger space means more materials, labor, and potential logistical challenges. Here’s a quick comparison of common master bathroom layouts:

  • A small primary bath (similar to a hall bath) with dual sinks.
  • A medium-sized bath featuring a separate tub and shower.
  • A large, luxurious bathroom with every feature imaginable.

2. Construction and Logistical Challenges

Several hidden factors can drive up the cost of your project:

  • Tile flooring: Is the existing floor thin-set or mud-set? Removing mud-set tiles is more labor-intensive.
  • Lead-safe practices: Homes built before 1978 require additional precautions to comply with EPA regulations.
  • Site access: Are you in a multi-level home? Is parking limited? These logistical challenges can affect labor efficiency.
  • Permits: A permit is often required to ensure the remodel meets local codes.

3. Mechanical and Electrical Upgrades

Older homes often have outdated plumbing or electrical systems that need to be upgraded:

  • Are there galvanized pipes that need replacing?
  • Does a radiator need to be removed or repositioned?
  • Are you adding or upgrading lighting fixtures, fans, or heated floors?
  • Is the layout changing? Moving plumbing or electrical lines adds cost.

4. Design and Material Choices

Design decisions play a huge role in the budget. Consider:

  • Types of materials: Are you opting for premium tiles, quartz countertops, or custom cabinetry?
  • Special features: Heated floors, wet rooms, statement tubs, or frameless glass enclosures.
  • Reorganizing space: Are you borrowing space from adjoining rooms or creating new layouts?

Why Are Master Bathrooms So Expensive?

Master bathrooms are complex spaces that involve:

  • Multiple trades: Framing, plumbing, electrical, tiling, cabinetry, countertops, shower glass installation, and more.
  • High material costs: Quality cabinetry, fixtures, stone, and custom features quickly add up.
  • Labor-intensive work: Tilework, especially intricate designs, requires precision and time.


Additionally, every bathroom remodel is unique. While these scenarios provide a general frame of reference, your specific project may fall above or below these ranges depending on the size, features, and challenges.

How to Make the Most of Your Budget

Here are a few tips to get the best value from your remodel:

1. Prioritize must-haves:

Focus your budget on features that matter most to you, like a luxurious shower or double vanity.

2. Simplify the layout:

Keeping plumbing and electrical in their existing locations can save thousands.

3. Opt for a mix of materials:

Use premium finishes sparingly for focal points (e.g., statement tile for the shower wall) while keeping the rest more budget-friendly.

4. Plan ahead:

Work with a professional design-build team to avoid surprises and ensure a smooth process.

So, How Much Does It Cost to Remodel a Master Bathroom?

The short answer? It depends.
A master bathroom remodel can range from $70,000 to over $200,000, depending on the size, design, and complexity of your project. While primary bathrooms are an investment, they add immense value to your home and create a personal oasis for you to enjoy every day.
