What Affects the Cost?

Bathroom Size

Larger bathrooms require more materials, more tiling, and more labour. A small cloakroom (toilet and basin only) might cost £1,500-£3,000, while a large master bathroom could cost double a standard bathroom.

Plumbing Changes

Moving plumbing positions is one of the biggest cost drivers. Keeping sanitaryware in existing positions saves significant money. Moving a toilet to a different wall requires below-floor drainage work.

Tiling Costs

Tiling is labour-intensive. Allow £40-60 per m² for professional installation, plus the cost of tiles themselves (from £10/m² for budget ceramic to £100+/m² for natural stone).

Underfloor Heating

Adds £500-£1,500 depending on the system (electric mats vs water-fed). Worthwhile investment for comfort, but factor into your budget.

Quality of Sanitaryware

Bathroom suites start from £300 for budget options, rising to £3,000+ for designer brands. Taps and showers range from £50 to £2,000+.

What's Usually Included vs Excluded

Typically included in labour quotes:

• Strip-out and disposal of old bathroom
• Plumbing adjustments
• Tiling (walls and floors)
• Installation of sanitaryware
• Making good (painting, plastering)

Usually quoted separately:

• Sanitaryware (bath, toilet, basin) — often purchased by homeowner
• Taps and showers
• Tiles (sometimes)
• Accessories (mirrors, towel rails, shelves)

Getting Accurate Quotes

1. Provide a floor plan or measurements
2. List the products/brands you want
3. Explain any plumbing changes needed
4. Ask for itemised breakdowns
5. Get at least 3 quotes
6. Check references and view previous work

Value Added

A well-executed bathroom renovation can add 3-5% to your property's value. In a £300,000 property, that's £9,000-£15,000 added value — often exceeding the cost of the renovation itself.

Modern bathrooms are a key selling point for buyers, particularly in family homes where a second bathroom is highly sought after.
