2. Do the Demolition Yourself

Removing old fixtures, tiles, and fittings yourself can save £500-£1,000 in labour costs. Just ensure you:

1. Turn off water and electrics safely
1. Protect the floor and surrounding areas
1. Dispose of waste responsibly
• Take photos before demolition

3. Choose Cost-Effective Materials

1. Ceramic over porcelain tiles: Save 20-40%
1. Acrylic over stone/steel baths: Save 50-70%
1. Standard over designer brands: Save 30-50%
• Shower over separate bath/shower: Save £500-£1,500

4. Limit Tiling Coverage

1. Splash back only: Instead of full-room tiling saves £800-£2,000
1. Half-height walls: Instead of floor-to-ceiling saves £500-£1,200
• Moisture-resistant paint: For non-wet areas saves £400-£800

5. Buy Materials Yourself

Purchasing materials directly (when confident in choices) can save 10-20% on trade markup. However:

1. Ensure compatibility of all components
1. Factor in delivery costs
1. Check return policies
• Coordinate delivery timing with installation

6. Book During Quiet Periods

Winter months (November-February) often have:

1. 10-15% lower labour rates
1. Better tradesperson availability
1. More willingness to negotiate
• Faster project completion

7. Use a Bathroom Fitter Instead of Multiple Trades

A qualified bathroom fitter can handle plumbing, tiling, and basic electrical work, potentially saving £800-£2,000 compared to hiring separate specialists.

8. Select Ready-Made Over Bespoke

1. Off-the-shelf vanities: Save £500-£2,000 vs. bespoke
1. Standard shower enclosures: Save £400-£1,500 vs. custom
• Ready-made tile schemes: Save on design fees
