How to Choose the Right Bathroom Contractor in London?
Choosing the right contractor can mean the difference between a smooth, stylish bathroom upgrade and a months-long headache.
Here’s how to choose smart and how the companies in this list stack up on the key decision points:
Scope & Budget Alignment
Start by being clear on what you need: a full gut-and-redo, a simple refresh, or something in between.
Budget accordingly (add a 20% buffer for surprises) and find a contractor that works well within those boundaries.
- Best for full renovations: Bathroom Fitters London, KBB Master Builder, and The London Bath Co.
- Good for smaller or budget-friendly projects: The Diamond Bathroom Fitters, South London Fitters
- Less ideal for tight budgets: Pimlico Plumbers – costs are often seen as high for the scope
Experience & Specialisation
Look for experience that matches your specific project – be it a small en-suite, loft bathroom, or wetroom.
- Best for complex or specialised installs: KBB Master (great with lofts/refurbs), Indesign (strong on small spaces and tech), Deluxcore (design-led spaces)
- Best for local hands-on craftsmanship: South London Fitters, The Diamond
- Less suited to bespoke projects: Pimlico Plumbers – better for standard installs
Credentials & Insurance
Professional affiliations add peace of mind, especially when structural or plumbing work is involved. Public liability insurance is a must.
- Top marks for accreditation: KBB Master, Red Box London, The London Bath Co., Pimlico Plumbers
- Still reputable, but less formal affiliation listed: Bathroom Fitters London, The Diamond, Deluxcore
- South London Fitters: Known for craftsmanship, but doesn’t advertise formal certifications
Portfolio & Reviews
Real photos and consistent reviews matter more than polished marketing. Look for detail in both.
- Best-reviewed with strong visuals: Indesign, Red Box, Deluxcore, Bathroom Fitters London
- Best word-of-mouth reputation: South London Fitters – often recommended locally
- Some mixed reviews: Pimlico Plumbers – great for speed, but inconsistent experience
Communication & Transparency
A contractor who listens, explains, and keeps you updated is worth their weight in gold. Look for detailed quotes and someone you feel comfortable with.
- Best for structured, clear processes: Indesign, Deluxcore, Red Box
- Highly rated for responsiveness: Bathroom Fitters London, The Diamond, South London Fitters
- Room to improve: Pimlico Plumbers – fast response but mixed on follow-through
Frequently Asked Questions

Most standard bathroom renovations take 1 to 3 weeks, depending on complexity. Full refurbishments or projects requiring structural work may take longer – always confirm timelines in writing.
