Choosing the wrong bathroom fitter can turn your dream renovation into a nightmare. Here's how to find a quality professional in London and what to watch out for.
A bathroom renovation is one of the biggest investments you'll make in your home, and choosing the right fitter is the single most important decision in the process. London has thousands of bathroom fitters — from sole traders to established companies — and the quality varies enormously. Here's how to separate the professionals from the cowboys.
Essential Questions to Ask
1. Can I see your recent work?
Any reputable bathroom fitter should have a portfolio of completed projects — ideally with before and after photos, and even better, 360° panoramic views. Look at the details: are the grout lines straight? Is the silicone neat? Are the tile cuts clean, especially around pipework and corners? These finishing details reveal the true quality of a fitter's work.
2. Do you provide a detailed, itemised quote?
Beware of one-line quotes like "Bathroom renovation: £8,000." A professional quote should break down every element: strip-out, waste disposal, plumbing, electrical, waterproofing, tiling, fixtures, and finishing. This protects both you and the fitter, and prevents surprise costs later.
3. Who does the electrical and plumbing work?
Electrical work in bathrooms must comply with Part P building regulations and BS 7671 wiring standards. Ask whether the fitter uses qualified, registered electricians and plumbers, or whether they handle everything themselves. Multi-trade companies that keep everything in-house typically deliver better-coordinated results.
4. What guarantees do you offer?
Look for a workmanship guarantee of at least 12 months, separate from any manufacturer warranties on products. A fitter who stands behind their work will have no problem offering this.
Red Flags to Watch For
- No portfolio or references — Good fitters are proud of their work and happy to show it
- Demands large upfront deposits — A reasonable deposit structure is 10-20% to secure the booking, with stage payments thereafter
- Vague timelines — A professional should give you a clear programme of works with expected completion date
- No written contract — Everything should be documented: scope, cost, timeline, payment terms, and guarantee
- Unrealistically low quotes — If a quote is significantly below others, something is being cut: quality materials, proper waterproofing, qualified electricians, or time spent on finishing
What Good Looks Like
A quality bathroom fitter will:
- Visit your property before quoting (never quote from photos alone for a full renovation)
- Provide a detailed, written quote with clear payment terms
- Show you completed projects similar to yours
- Explain the process from start to finish so you know what to expect
- Handle all trades (plumbing, electrical, tiling, plastering) under one roof
- Offer a clear workmanship guarantee
- Leave the site clean at the end of each working day
