What Can Go Wrong in a Bathroom Renovation — and How to Avoid It
Let’s be real—bathroom renovations don’t always go to plan.
Tiles show up broken. Waterproofing fails. Trades ghost. You’re left with an unfinished bathroom and a long line of excuses.
At Bluestone Build Co., we’ve taken over projects where things have gone sideways—and it’s always the same handful of problems.
Here’s what can go wrong in a bathroom renovation, and more importantly, how to avoid it.
1. Poor Planning and Rushed Quotes
A rushed bathroom quote that skips the details? That’s your first red flag.
What can go wrong:
Blowout in budget mid-build
Trades working off assumptions
Unclear inclusions (what’s actually being done?)
How to avoid it:
Demand a clear scope of work. Ask for line items. Confirm what’s included, what’s excluded, and how variations are handled. If a builder can’t explain the quote — run.
2. Wrong Builder for the Job
Not all builders are bathroom specialists. Some subcontract everything. Others take on more work than they can handle.
What can go wrong:
Lack of quality control
Delays from poor coordination
No single point of accountability
How to avoid it:
Choose a builder who actually manages the entire renovation — not just a middleman handing off trades. At Bluestone Build Co., we run the show from start to finish.
3. Waterproofing Issues
This one’s a big one—and it can take years to reveal itself.
What can go wrong:
Leaks behind walls
Rotting floor joists
Structural damage
Total bathroom rebuild
How to avoid it:
Only use licensed waterproofers. Always request waterproofing certificates. Skimping here is one of the most expensive mistakes you can make.
4. Wrong Tile Choices
Big tiles in tight spaces. Gloss tiles on floors. Poor grout selection. Tiles can make or break a bathroom.
What can go wrong:
Slippery surfaces
Awkward layouts
Visible lippage (uneven edges)
How to avoid it:
Use a builder who helps you choose smart — not just what looks nice in the showroom. And always test samples under your actual bathroom lighting.
5. Hidden Plumbing Problems
Bathrooms can hide all sorts of nasty surprises once walls are open.
What can go wrong:
Rusted pipes
No proper fall (water pooling)
Outdated layouts causing blockages
How to avoid it:
Have your plumber inspect early and build a contingency into your budget for unexpected plumbing issues. Good builders prepare you for this — bad ones blame you later.
6. Delays, Delays, Delays
Sometimes it's product delays. Sometimes it’s trades not showing up. Either way—it adds time and cost.
What can go wrong:
Bathroom out of action for weeks
Temporary fixes costing you more
Project fatigue (yes, it’s a thing)
How to avoid it:
Lock in your build date, order materials early, and work with a team that builds to schedule—not vibes.
