Thinking about renovating your bathroom? It's one of the best investments you can make in a London property — a well-designed bathroom adds real value and makes a huge difference to everyday life. But costs can vary enormously depending on the size of the bathroom, the spec of the materials, and the scope of work involved.
As a plumbing and building specialist working across London and surrounding areas, we've completed hundreds of bathroom renovations. Here's an honest breakdown of what you can expect to pay in 2026.
Bathroom Renovation Cost Overview (London, 2026)
| Type of Renovation | What's Included | Typical Cost |
|---|---|---|
| Basic refresh | Replace toilet, basin, taps. Minor tiling patch. No structural changes. | £1,500 – £3,000 |
| Mid-range renovation | New suite, full retiling, new shower, basic fitting. Labour + materials. | £4,000 – £8,000 |
| Full fit-out | Complete strip-out, new layout, premium tiles, walk-in shower, underfloor heating. | £8,000 – £15,000+ |
| Luxury renovation | Designer suite, statement tiling (e.g. marble effect), bespoke features, high-end finishes. | £15,000 – £30,000+ |
These are guide prices including labour and standard materials. Costs vary based on bathroom size, existing condition, and material choices.
What Affects the Cost?
1. Size of the Bathroom
Larger bathrooms need more tiles, more flooring, and more labour time. An en-suite will cost less than a full family bathroom. A master bathroom with a walk-in shower and freestanding bath will cost considerably more.
2. Layout Changes
If you're moving the toilet, bath, or shower to a different position, the plumber needs to reroute pipework — this adds significant cost. Keeping the existing layout and just updating the fixtures is always cheaper.
3. Tiles and Materials
Tiles range from £15/m² for basic ceramic to £150+/m² for premium marble-effect or stone. The difference between a mid-range and a high-end renovation is often almost entirely in the material choices. Labour to lay complex patterns (herringbone, large format) also costs more.
4. Labour Rates in London
London labour rates are higher than the rest of the UK. A qualified plumber in London charges £50–£80/hour; a tiler £40–£70/hour. A full bathroom renovation typically takes 1–2 weeks of labour for a team of two.
5. Condition of Existing Bathroom
If we strip out the old bathroom and find rotted joists, waterlogged plasterboard, or outdated pipework that needs replacing, this adds to the cost. We always let you know before proceeding with any additional work.

Our Approach: Fixed Prices, No Surprises
At JR Plumbing and Services, we quote you a fixed price before any work starts. We know homeowners in London have been burned by contractors who quote low and then add on extras — that's not how we work. If we find something unexpected during the job that genuinely changes the scope, we'll discuss it with you before doing anything.
