A bathroom renovation can add value to your home, but it’s easy to make expensive mistakes. If you’re planning updates, avoid these common issues to keep your project on track. Bathroom renovation mistakes often stem from poor planning, cutting corners, or selecting the wrong materials.
Ignoring the layout
You might want a double vanity or larger shower, but if the layout doesn’t support it, forcing it in can backfire. Plumbing changes add cost. Consider how the space functions on a day-to-day basis. A nice-looking bathroom won’t matter if it’s hard to move around in.
Choosing the wrong materials
Bathrooms deal with moisture, so materials must be able to handle it. Skip hardwood, some laminates, and porous tiles unless they’re treated properly. Cheap finishes may peel or warp quickly. Stick with materials designed for wet spaces.
Overdoing the trends
It’s tempting to follow the latest look, but some trends fade fast. You can update hardware or paint later, but expensive tile or custom vanities are harder to swap out. Keep the big-ticket items simple and functional.
Poor lighting
Good lighting matters. Don’t rely on one overhead fixture. Add task lighting near the mirror and consider wall sconces. Poor lighting makes the room feel smaller and harder to use.
Skipping ventilation
A bathroom without a proper fan will grow mold and mildew over time. Even if there’s a window, install a vent fan that vents outside, not into the attic.
Underestimating the budget
Renovations often cost more than expected. Account for labour, materials, and a buffer for surprises. Don’t forget fixtures, paint, and accessories. If your plan maxes out the budget, you have no room for errors or upgrades.
Hiring the wrong contractor
Check references, read reviews, and look at past work. A bad contractor can drag the job out, go over budget, or leave things unfinished. Always get a clear written quote and timeline.
Not planning for storage
A new bathroom that looks great but has nowhere to put towels or toiletries won’t feel finished. Build in storage from the start. Think about what you use every day and where it will go.
Avoiding these bathroom renovation mistakes will save time and money—and give you a space that works for years. Plan smart, spend where it matters, and don’t rush decisions.
