Bathroom Renovation Guide: Design, Planning & Installation

Whether you want a spa-like retreat or a practical family bathroom, renovation requires careful planning. Bathrooms pack complex plumbing and electrical requirements into a small space, meaning every inch counts.

Why Renovate?

• Modernization: Replacing avocado suites and dated tiles.
• Accessibility: Replacing a bath with a walk-in shower.
• Water Damage: Fixing leaks, rot, or mold issues.
• Resale Value: A pristine bathroom is a major buyer incentive.

Phase 1: Planning

• Assess Needs: Bath vs Shower? Twin sinks? Storage needs?
• Soil Pipe: Moving the toilet is the hardest/most expensive part. Try to keep the layout similar if budget is tight.
• Water Pressure: Check if your system can support that rainfall shower or body jets.

Phase 2: Design & Fixtures

• Sanitaryware: Wall-hung toilets and basins create a sense of space and are easier to clean.
• Showers:
  • Enclosure: Classic tray and glass door.
  • Wet Room: Fully tanked floor, level access.
  • Digital Shower: Precise temperature control.
• Baths: Freestanding (statement piece) vs Built-in (practical).
• Taps: Mixer taps look cleaner and regulate temp better than separate pillars.

Phase 3: Materials

• Tiles: Porcelain is harder wearing than ceramic. Large format tiles mean less grout lines to clean.
• Flooring: Non-slip tiles or LVT. Never carpet or solid wood.
• Paint: Must be specialist bathroom/kitchen paint that resists moisture.

Lighting & Ventilation (Critical!)

Ventilation: An extractor fan is mandatory. Relying on a window isn't enough to prevent mold in winter. Get a timer fan that runs after the light goes off.

Lighting: IP (Ingress Protection) ratings matter. Zone 1 (above shower) needs IP65. Zone 2 (near water) needs IP44.

The Process (6 Steps)

1. Strip Out: Removing old suite and tiles.
2. First Fix: Plumbing pipework adjustments and electrical cabling.
3. Preparation: Boarding walls (use moisture-resistant plasterboard or tile backer boards) and tanking (waterproofing) wet areas.
4. Tiling: Walls and floors.
5. Second Fix: Fitting the toilet, basin, bath, shower, radiators, and lights.
6. Sealing: Silicone sealant is the final barrier against leaks.

Budget Breakdown

• Labour (Plumbing/Tiling/Electric): 40%
• Sanitaryware & Brassware: 25%
• Tiles & Materials: 20%
• Lighting & Heating: 10%
• Contingency: 5%

Common Mistakes

• Not Tanking: Skipping waterproofing in shower areas leads to leaks downstairs.
• Bad Spacing: Toilet too close to the wall or door hitting the basin.
• Slippery Tiles: Choosing polished gloss tiles for the floor (safety hazard).
• No Storage: Cluttered surfaces ruin the look. Install a vanity unit.
