How to price bathroom fitting jobs in the UK

Pricing bathroom work: beyond guesswork

Bathroom fitting is one of the hardest trades to price accurately. Every job is different. The Victorian terrace with lead pipes, the new-build with hidden waste runs, the customer who changes their mind about tile layout halfway through. You need a pricing method that accounts for all of this without leaving money on the table or scaring off customers.

Break the job into stages

Price each stage separately, then add them up. This gives you a transparent quote the customer can understand and protects you if the scope changes.

• Strip out — removing the old suite, tiles, and any rotten timber. Allow 1 to 2 days for a standard bathroom. £300 to £600.
• First fix plumbing — moving or installing hot, cold, and waste pipes. £400 to £800 depending on how much needs moving.
• First fix electrics — downlights, extractor fan, heated towel rail circuit. Needs a Part P registered electrician. £200 to £500.
• Boarding and prep — plasterboard, Hardiebacker for wet areas, floor levelling. £300 to £600.
• Waterproofing — tanking a shower area or wet room. £200 to £400.
• Tiling — walls and floor. £600 to £1,500 depending on area and tile type.
• Second fix plumbing — connecting the suite, taps, shower. £300 to £500.
• Second fix electrics — fitting lights, fan, towel rail. £150 to £300.
• Finishing — silicone, grouting, snagging, cleaning. £100 to £200.

Materials: quote separately or include?

Some bathroom fitters supply and fit. Others quote labour only, with the customer buying their own suite and tiles. Both approaches work. If you supply materials, add 10 to 20 per cent markup. This is standard practice and covers your time sourcing, collecting, and dealing with any returns.

If the customer supplies, make clear in your quote that delays from missing or incorrect materials are charged at your day rate. This protects you from sitting around waiting for tiles that arrive in the wrong colour.

How long does a bathroom take?

A like-for-like suite swap with retiling takes 5 to 7 working days. A full strip-out with layout changes, wet room installation, and custom tiling takes 8 to 14 days. Factor in drying times for tanking membranes and adhesive, which cannot be rushed without risking failures.

Be honest with customers about timescales. Overpromising and underdelivering damages your reputation faster than almost anything else.

Pricing for profit, not just survival

Add up your direct costs (materials, subcontractor costs, skip hire), add your labour (days multiplied by your day rate), then add 15 to 25 per cent for overhead and profit. Your overhead includes van costs, insurance, tools, marketing, and admin time. If you are not adding a profit margin on top of your day rate, you are effectively working for free during the hours you spend quoting, invoicing, and managing the business.

Use the profit margin calculator to check your margins. If they are below 15 per cent consistently, your prices need reviewing.

Quoting vs estimating

A quote is a fixed price. An estimate is an approximation. For bathroom work, I recommend providing a detailed quote with clearly stated exclusions. List exactly what is included and what is not. Common exclusions: structural work, asbestos removal, upgrading incoming water supply, and anything behind finished walls that cannot be assessed until strip-out.

Include a clause for unforeseen work. Something like: "Additional work discovered during strip-out (e.g. rotten joists, failed waterproofing, non-compliant plumbing) will be quoted separately before proceeding." This protects both you and the customer.

Step-by-step guide to quoting

Creating an accurate quote involves several steps. Follow this guide to ensure you cover all bases:

1. Initial consultation: Visit the site, discuss the customer's needs, and assess existing conditions. Take measurements and photos.
2. Scope of work: Define the scope clearly. What exactly will you do? What materials will be used?
3. Cost calculation: Break down costs for each stage of the job. Use our day rate calculator to ensure your labour costs are accurate.
4. Markup and profit: Apply markup to materials if you're supplying them. Add your profit margin to the total.
5. Draft the quote: Prepare a detailed quote document. Include a breakdown of costs, exclusions, and terms.
6. Review with customer: Go through the quote with the customer. Ensure they understand everything and agree to the terms.
7. Formal agreement: Once the customer agrees, both parties should sign the quote. This formalises the agreement.

Common pitfalls and how to avoid them

Bathroom fitting can be fraught with challenges. Here are some common pitfalls and how to avoid them:

• Inaccurate measurements: Double-check all measurements. Mistakes here lead to costly errors later on.
• Assuming customer understands: Never assume the customer understands industry terms. Explain everything clearly.
• Ignoring drying times: Skipping drying times for adhesives and waterproofing may result in failures. Always factor these into your timeline.
• Lack of documentation: Document all changes and agreements in writing to avoid disputes.
• Underestimating costs: Use tools like the VAT calculator to ensure all taxes and fees are accounted for.

Using technology to streamline your business

Incorporating technology into your workflow can greatly enhance efficiency. Consider using the following tools:

• Invoice management: Use our invoice generator to create professional invoices quickly.
• Project management apps: Tools like Trello or Asana can help you keep track of projects, deadlines, and communications.
• Cost tracking software: Apps like QuickBooks or Xero can help manage your finances and track expenses.
• Communication tools: Use communication tools like WhatsApp or Slack for quick updates and instant messaging with clients.

Case study: pricing a real-world project

Let's walk through a real-world example to see how these principles apply:

Project: Full bathroom renovation in a Victorian terrace.

Initial consultation: The client wanted a modern bathroom with a walk-in shower, underfloor heating, and feature lighting.

Scope of work: Total strip-out, reconfiguration of plumbing, installation of underfloor heating, tiling, and fitting of a new suite.

Cost breakdown:

• Strip out: £500
• Plumbing first fix: £700
• Electrics first fix: £400
• Boarding and prep: £500
• Underfloor heating installation: £1,200
• Tiling: £1,300
• Second fix plumbing: £400
• Second fix electrics: £250
• Finishing: £200

Total cost: £5,450 before markup and profit.

Profit margin: Applied a 20% profit margin, bringing the total to £6,540.

Outcome: The project was completed within budget and timeline, resulting in a satisfied customer and positive referral.

FAQs

Should I charge a deposit?

Yes. 25 to 30 per cent on signing, with the balance due on completion. The deposit covers your materials purchase and commitment. Use a deposit invoice to formalise it.

What day rate should I charge for bathroom fitting?

In 2026, experienced bathroom fitters in England charge £200 to £350 per day depending on location. London rates are higher at £250 to £400. Scotland and Wales are slightly lower. Use the day rate calculator to work out what you need based on your costs and target income.

How do I handle customers wanting to change the spec mid-job?

Document every change in writing, even a text message. Provide a revised price before proceeding with the changed work. Verbal agreements about changes are the number one source of disputes in bathroom fitting.

Is it necessary to have insurance for bathroom fitting work?

Yes, having public liability insurance is crucial. It protects you against claims of property damage or injury caused during the course of your work. Check the gov.uk website for more information on the types of insurance needed for tradespeople.

What should I do if I encounter unexpected asbestos during a job?

Stop work immediately and inform the customer. Do not attempt to handle asbestos yourself unless you are licensed to do so. Advise the client to contact a licensed asbestos removal contractor. For more guidance, refer to the HSE asbestos management page.
