Top Mistakes to Avoid in Renovation vs. Remodeling Projects
Updating your bathroom, whether it’s a surface-level renovation or a full remodel, is one of the most satisfying ways to improve your home.
But it’s also a project where a few wrong moves can lead to frustration, budget overruns, or results you’re not happy with.
Over the years, I’ve spoken with countless homeowners who underestimated what it really takes to transform a bathroom. Before diving into the common pitfalls, it’s helpful to understand the key difference between renovation and remodeling. Read our renovation vs remodel guide to clarify how each impacts your project scope and cost. Some overspent on finishes and had to cut corners on plumbing. Others jumped in with a contractor before having a clear plan.
The good news? Most of these missteps are avoidable.
Let’s walk through the most common mistakes made during bathroom renovations and remodels and how to steer clear of them.
Common Planning and Budget Errors
1. Not Knowing the Difference Between Renovation and Remodel
This sounds simple, but it’s a surprisingly common issue. Many people use “renovation” and “remodel” interchangeably, even though they involve very different scopes of work.
Renovation: Updates the appearance and fixtures without major layout or plumbing changes.
Remodel: Involves changing the layout, moving walls or plumbing, and often requires permits and inspections.
Why this matters: Mistaking one for the other can throw off your timeline, budget, and expectations right from the start. You can also explore our bathroom renovation vs remodel cost article for a clear breakdown of what to expect financially.
2. Setting an Unrealistic Budget
Bathrooms are small, but they’re expensive. Even a modest renovation can add up quickly, and a full remodel can involve multiple trades and weeks of work.
Mistake: Planning for materials only and forgetting about labor, permits, contingencies, or inspection fees.
What to do instead:
Build in a 10–20% buffer for unexpected issues.
Work with a contractor to get a full project estimate, not just material costs.
We discuss more on proper budgeting and timing in our bathroom renovation timeline guide.
3. Ignoring Existing Plumbing and Electrical
Even in a renovation, some updates such as replacing a tub with a walk-in shower or changing lighting locations may require plumbing or electrical changes.
Avoid this by: Asking early on if your plans involve behind-the-wall updates and confirming whether you’ll need permits or inspections. If you’re unsure about permit requirements, check our bathroom remodel permits guide.
4. Hiring the Cheapest Contractor
It’s tempting to go with the lowest bid, but cheaper doesn’t always mean better. It often means cut corners, rushed timelines, or inexperienced installers.
Instead:
Check credentials, licenses, and reviews.
Ask about warranties, communication, and project management.

Misunderstandings About Design and Scope
5. Starting Without a Clear Design Plan
Jumping in without a detailed design can lead to mismatched finishes, awkward layouts, and extra trips to the tile store.
What to avoid:
Picking fixtures before measuring your space.
Changing design choices mid-project, which causes delays and extra costs.
Solution: Work with a design-build team like Equinox Builders, or make sure your contractor offers planning services up front. You can also view our modern bathroom renovation ideas for layout and design inspiration before starting your project.
6. Choosing Materials Based on Looks Alone
That sleek marble tile might be beautiful, but is it slippery when wet? That trendy black faucet might look great, but does it show water spots every time you use it?
Mistake: Prioritizing style over durability, ease of cleaning, or compatibility with your lifestyle.
Tip: When selecting materials, always ask:
How will this hold up over time?
Is it easy to clean?
Does it work in a humid, high-traffic space?

7. Underestimating How Layout Impacts Use
In a remodel, layout changes should improve function, not just look good on paper. Don’t sacrifice usability for trends.
Example: A recent client wanted a large soaking tub in their small primary bath. But doing so meant losing counter space and storage. After a design consultation, we helped them find a freestanding tub that fit their layout without giving up what they really needed.

How to Prevent Costly Rework
8. Skipping Permits or Inspections
Even small changes, such as updating wiring or replacing a shower, may require permits, especially in cities like Seattle, Bellevue, or Tacoma.
Skipping this step can result in:
Fines
Delays
Rework
Problems during resale
Do it right the first time: A reputable contractor will handle this for you and ensure everything meets current codes. For eco-conscious updates that comply with modern standards, see our eco-friendly bathroom renovation guide.
9. Ordering Materials Too Late
A common cause of delays is waiting until the project has started to order tile, fixtures, or vanities.
Some products have lead times of 6–10 weeks, and that can leave your entire project on pause.
How to avoid it:
Finalize all selections before demolition begins.
Order materials early, or work with a contractor who handles this for you.
Our luxury bathroom renovation trends article also shares which high-end finishes often have longer lead times.
10. Not Planning for the Disruption
Even a simple renovation can impact your daily routine, especially if you only have one bathroom. Some homeowners don’t plan for the mess, noise, or downtime.
Be prepared to:
Set up a temporary bathroom if possible.
Move toiletries and valuables out of the space.
Be flexible with timelines, as weather, material delays, and inspections can shift things.
Example: In one Tacoma remodel, a family underestimated how much the project would disrupt their schedule. We helped them set up a temporary sink and provided weekly updates so they always knew what to expect. If you want a stress-free experience, consider our bathroom remodeling services we handle design, logistics, and scheduling to minimize disruption.
