Bathroom renovation quotes in London vary enormously — a figure of £4,500 and a figure of £22,000 can both be legitimate quotes for what a homeowner initially describes as "redo the bathroom." The gap almost always comes down to a handful of specific decisions: whether pipework is moving, how extensive the tiling and waterproofing scope is, and what tier of fixtures you're specifying. This guide sets out realistic 2026 London pricing across the full range, and what actually drives the difference.
Before committing to a scope, Seven's free video consultation lets you walk a vetted professional through your bathroom and goals remotely — getting a realistic price band and trade sequence before anyone travels to your property.
London Bathroom Renovation Costs at a Glance
The table below sets out realistic 2026 pricing across the main project types London homeowners consider. These reflect typical London labour and material costs; exact figures depend heavily on the specifics covered later in this guide.

A note on why "budget" doesn't mean "corners cut": a well-executed budget renovation with sound waterproofing and standard fixtures is a perfectly sensible choice — the budget tier reflects fixture and layout decisions, not necessarily lower-quality workmanship. The place to never economise, regardless of budget tier, is waterproofing, since a failure there is far more expensive to fix later than it would have cost to do properly the first time.
What Actually Drives the Price Up or Down
Three decisions explain most of the variation between renovation quotes for what sounds like a similar-sized bathroom.
Whether pipework is moving. Keeping the bath, shower, WC and basin in their existing positions is the single most effective way to control costs — it avoids new pipe runs, floor lifting, and additional waterproofing around new fixture positions. Moving even one fixture to a new location can meaningfully increase both cost and project duration, since it typically means opening up the floor and re-routing supply and waste pipework.
Tiling and waterproofing extent. Full floor-to-ceiling tiling with a larger format and proper tanking to current standards costs considerably more than partial-height, budget tiling — but this is one area where spending more genuinely reduces long-term risk, since tanking failures are difficult and expensive to fix after the tiles are in place.
Fixture specification. A budget suite (WC, basin, bath or shower enclosure) versus premium branded sanitaryware and tapware can double the fixtures line item on its own, entirely independent of labour costs. This is usually the most controllable cost lever for homeowners working to a fixed budget.

Ensuite and Wetroom Pricing Explained
These two project types consistently confuse homeowners comparing quotes against a standard bathroom renovation, because they involve fundamentally different scopes of work.
An ensuite installation typically means running entirely new pipework, drainage, and electrics to a room — often a bedroom corner — that had none of this infrastructure before. This is inherently more involved than renovating an existing bathroom, which explains why a relatively compact ensuite can cost as much as a larger standard bathroom renovation.
A wetroom conversion requires waterproofing (tanking) across the entire floor and lower walls, not just around a shower tray, along with carefully calculated drainage falls to ensure water flows correctly to the drain across the whole room. This is more technically demanding and time-consuming than a standard shower enclosure, which is reflected in the higher typical cost.

What a Fair Bathroom Renovation Quote Should Include
A written quote should itemise labour for each trade involved (plumbing, electrical, tiling), separate fixture and material costs, waterproofing scope, and any building control notification fees where applicable — such as for a new unvented hot water system under Part G. It should also state clearly whether waste removal and making good to surrounding surfaces (like patching walls where old fixtures were removed) are included, since these are sometimes charged as extras.
Red flags to watch for: a single lump-sum figure with no breakdown by trade or material; no mention of waterproofing or tanking specification; vague language about who's responsible for coordinating the plumber, electrician and tiler; and no clarity on what happens if unexpected issues are found once the old bathroom is stripped out (a common and often unavoidable occurrence in older London properties).
Frequently Asked Questions
How much does a budget bathroom renovation cost in London?
A budget full bathroom renovation in London typically costs £4,500–£7,000. This covers standard fixtures, no pipework relocation, and a straightforward tiling scheme. Costs at this end are kept down by keeping existing plumbing positions and choosing mid-market rather than premium fixtures.
What's the difference between mid-range and premium bathroom renovation pricing?
A mid-range renovation (£7,000–£12,000) typically includes better quality fixtures and some layout flexibility. A premium renovation (£12,000–£25,000+) includes high-end sanitaryware, bespoke or large-format tiling, potentially underfloor heating, and often a full layout change with pipework relocation — the layout change and fixture specification are what drive most of the cost difference, not labour rates.
Why do ensuite and wetroom installations cost more than a standard bathroom?
An ensuite typically involves running entirely new pipework and drainage to a room that didn't previously have any, which adds cost over renovating an existing bathroom. A wetroom requires more extensive waterproofing (tanking) and precise drainage falls across the whole floor rather than just around a shower tray, which is more technically demanding and time-consuming to get right.
Does moving the toilet or shower position significantly increase renovation cost?
Yes, meaningfully. Relocating fixtures means new pipe runs, often lifting floors, and additional waterproofing work around the new positions. Keeping fixtures in their existing positions is one of the most effective ways to control renovation costs, since a large proportion of the cost difference between budget and premium renovations comes from layout changes rather than fixture quality alone.
What's included in a typical London bathroom renovation quote?
A proper quote should itemise labour for each trade (plumbing, electrical, tiling), fixture and material costs, waterproofing, and any building control notification fees where applicable (such as for a new unvented hot water system). It should also specify whether waste removal and making good to surrounding surfaces are included, since these are sometimes charged separately.
