Renovating a bathroom is one of the best ways to improve your home’s value, comfort, and style. Whether you're dreaming of a spa-inspired escape or just want to modernise a tired space, a bathroom renovation can make a huge impact. But before you grab your toolbox or call in a tradesperson, there are some key things to consider.

At Wise Guys DIY, we’ve helped thousands of homeowners and DIYers tackle renovations the smart way. Here’s your complete guide to bathroom renovations—from planning and design to budgeting and common pitfalls to avoid.

Why Renovate Your Bathroom?

Your bathroom is one of the most used rooms in your home. A well-designed space not only boosts daily comfort but also adds significant value to your property. Here are some top reasons people choose to renovate:

• Outdated style or fixtures

• Water damage or mould

• Inefficient layout

• Improved accessibility

• Increased home value

Step 1: Plan Your Bathroom Renovation

Before you start tearing out tiles, take time to plan your renovation. Ask yourself:

• What’s my budget?

• What’s my ideal layout?

• Do I need to move plumbing or electrics?

• Am I going full DIY or hiring a contractor?

Tip from the Wise Guys: Use free online tools or sketch out your floor plan. Knowing your space helps avoid costly mistakes down the line.

Step 2: Set a Realistic Budget

Bathroom renovations can range from a few hundred pounds for a simple refresh to £10,000+ for a complete remodel. Break your budget down into categories:

• Plumbing and electrics

• Tiles and flooring

• Fixtures (toilet, sink, bath, shower)

• Vanity units and storage

• Labour (if using professionals)

• Emergency or surprise costs (always budget 10–15% extra)

Step 3: Choose the Right Fixtures and Materials

Go for a balance of style and functionality. Think about:

• Water efficiency: Opt for low-flow toilets and showerheads.

• Durability: Porcelain tiles and quartz countertops are long-lasting.

• Style: Stick to a consistent theme—modern, rustic, minimalist?

Wise Guys Tip: Always read reviews before buying fixtures. A stylish tap isn’t much good if it leaks after 3 months.

Step 4: DIY vs. Hiring a Pro

Some tasks—like painting or replacing hardware—are perfect for DIY. But when it comes to plumbing, electrics, or structural work, hiring a qualified tradesperson is often safer (and legally required).

Step 5: Don’t Forget the Details

It’s the little things that bring your new bathroom together:

• Underfloor heating for added comfort

• LED mirror with anti-fog features

• Wall niches for shampoo storage

• Smart lighting or a Bluetooth speaker system

Make sure your finishing touches are both functional and fabulous.

Common Mistakes to Avoid

• Poor ventilation → Leads to mould. Install an extractor fan.

• Wrong material choice → Avoid wood-based products in wet zones.

• Overlooking lighting → Use a mix of ambient, task, and accent lighting.

• Skipping waterproofing → Always seal behind tiles and around wet areas.
