Modern, luxurious bathroom featuring a freestanding white bathtub near large windows, white marble flooring with gray veining, and a double-sink vanity with white cabinetry and chrome fixtures. Two round mirrors and multi-bulb light fixtures hang above the sinks. A glass-enclosed walk-in shower and a separate toilet room are visible in the background. The vaulted ceiling and geometric pendant light enhance the spacious feel, while a small green plant adds a natural touch.

One of the hardest parts of planning a bathroom renovation is figuring out what things actually cost. It can feel like contractors are speaking a different language when they hand you an estimate.

So how do you know if the price is fair?

Why Bathroom Estimates Vary So Much

Bathroom renovations can range anywhere from $10,000 to $30,000+ depending on finishes, materials, labor, and the scope of work.

When you start collecting estimates, you’ll probably notice a big spread in numbers. Here’s why:

Lowest estimates often leave things out. If a price looks too good to be true, it usually is. Some contractors leave out key details that later show up as costly “extras.”
Highest estimates may not be realistic either. On the other end of the spectrum, some bids have unnecessary costs.
The middle ground is often the most reliable. A strong estimate should clearly outline what’s included, where your money is going, and why.

Why Comparing Bathroom Estimates Is So Hard

One contractor might break everything down line by line, while another just hands you a single lump sum. That’s why homeowners often feel confused or pressured when trying to compare bids.

Our advice: Always get at least three estimates, and don’t just look at the final number. Pay attention to the details, that’s where the real differences are.
