Top 7 Mistakes Homeowners Make During a Bathroom Renovation (And How to Avoid Them)

A  bathroom renovation is one of the best investments you can make in your home — boosting comfort, resale value, and everyday functionality. But it’s also a project full of hidden pitfalls that can quickly turn into costly setbacks if not managed properly.

From skipped permits to short-sighted design decisions, here are the 7 most common bathroom renovation mistakes we see — and how SCL ensures your project stays on track, on budget, and up to code.

Some Mistakes during bathroom renovations are as follows:

1. 💸 Underestimating the Budget

It’s a common myth that you can fully renovate a bathroom for just a few thousand dollars. The truth? Between plumbing upgrades, demolition, finishes, and permit fees, costs can add up quickly.

At SCL, we always recommend building in a 15–20% buffer for unexpected expenses. Material prices fluctuate and hidden issues like outdated plumbing can impact scope. Our estimates are transparent and realistic, so you’re never caught off guard.

2. 🚫 Skipping Permits

In Ontario, most bathroom renovations involving plumbing, structural, or layout changes require permits. Skipping this step might seem like a shortcut, but it can lead to:

• Fines or project shutdowns

• Denied home insurance claims

• Problems during resale or home inspections

At SCL, we handle the entire permitting process for you, including paperwork and inspections — so you can renovate with confidence.

3. 👷 Hiring Unqualified Contractors

Bargain pricing often comes with hidden costs. We’ve seen horror stories from homeowners who hired unlicensed or uninsured contractors — leading to poor workmanship, unfinished projects, or legal issues.

SCL is fully licensed, WSIB-covered, and insured. Our team is trusted across Simcoe County for delivering safe, high-quality work backed by clear contracts and references.

4. 🧼 Choosing Style Over Function

That wall-mounted faucet may look sleek — but if it sacrifices counter space, you may regret it.

We always strike a balance between form and function, helping you choose finishes that look amazing and work for your daily needs. Our design approach prioritizes:

• Traffic flow

• Storage optimization

• Accessibility

• Long-term durability

5. 💧 Ignoring Moisture Protection

Bathrooms are wet zones — and poor waterproofing is one of the biggest DIY mistakes we see. Skipping proper moisture barriers can lead to mold, rot, and expensive repairs.

That’s why SCL uses premium systems like Schluter waterproofing membranes to ensure your bathroom is protected from behind the walls out.

6. ⏱️ Rushing the Timeline

We get it — you want your new bathroom ASAP. But rushing trades or skipping sequencing can lead to misaligned tiles, plumbing leaks, or finishing issues.

Our typical three-week bathroom timeline is optimized for flow:

• Week 1: Demolition & rough-ins

• Week 2: Tile, electrical, and inspections

• Week 3: Fixtures, paint, and finishing

We move quickly — but never cut corners.

7. 🗄️ Forgetting About Storage

Storage is one of the most overlooked elements in bathroom design. Without proper planning, you end up with cluttered counters and zero space for essentials.

SCL integrates smart storage solutions like:

• Floating vanities with deep drawers

• Built-in shower niches

• Recessed cabinets and shelving

All functional — and seamlessly built into your design.
