How much does a bathroom renovation cost in Birmingham? 2026 guide

"How much for a new bathroom?" is the question we get asked most, and it's the hardest one to answer over the phone. A bathroom is a small room with plumbing, electrics, tiling, waterproofing and ventilation crammed into it — change any one of those and the price moves. This is an honest breakdown of what a bathroom refit costs in Birmingham and the wider Midlands in 2026, and why the figure on your quote is what it is.

Every figure below is indicative — a realistic "from" starting point, not a quote. We price bathrooms after we've stood in the room, because the floor and the walls decide half the cost and you can't see either from a photo.

Scope 1: Like-for-like replacement

Same layout, same positions. Bath out, bath in. Basin, WC and taps swapped, walls re-tiled, floor re-laid, room re-decorated. No walls moved, no pipework re-routed beyond connecting in. Usually 5–7 working days on site. Indicatively from around £4,000–£5,500 including a mid-range suite and standard ceramic tiling.

This is the best value bathroom you can buy, by some distance, and it's what most of our Birmingham and Walsall customers end up choosing once they see the difference in price.

Scope 2: Full re-design, mid-spec

The layout changes. Bath comes out and a large shower enclosure goes in, the WC moves to the other wall, a vanity unit replaces the pedestal basin. That means first-fix plumbing to new positions, new waste runs (often the fiddliest part in a 1930s Birmingham semi), boarding and skimming, larger-format tiling and usually electric underfloor heating. Typically 10 working days. Indicatively from around £8,500–£13,000 depending on tile and sanitaryware choice.

Scope 3: Wet room conversion

A proper wet room means a former set into the floor, a fully tanked (waterproofed) floor and lower wall, a linear or centre drain, and falls tiled accurately enough that water actually goes where it should. On a suspended timber floor the joists usually need notching or a low-profile former, which adds a day or two. Typically 10–14 working days. Indicatively from around £11,000, and more where the floor build-up needs structural attention.

We also fit level-access and adapted bathrooms — grab rails, shower seats, low-threshold trays — which often sit somewhere between scope 2 and a full wet room. If it's an adaptation for a tenant or a family member, tell us on the survey and we'll spec it properly rather than retro-fitting rails afterwards.

Where the money actually goes

• Labour — normally 45–55% of a bathroom. It's a small room but it needs a plumber, a tiler, a plasterer, an electrician and a decorator, and they can't all be in there at once.
• Tiling — the single biggest swing factor. Standard 300x600 ceramics are a fraction of the cost of large-format porcelain or natural stone, and big tiles also take longer to lay and need a flatter substrate.
• Sanitaryware — a solid mid-range suite does the job. Where it's worth spending is the shower valve and the taps: brassware is what fails first and what you touch every day.
• Waterproofing and substrate — tile backer board and a tanking system behind the shower is not the place to save £200. Tiling straight onto old plaster in a wet area is the most common reason we get called back to somebody else's bathroom.
• Extras that appear after strip-out — rotten floorboards, buried old waste pipes, and walls that are nowhere near plumb. In a pre-war Midlands house, budget a contingency of about 10%.

The five extras people forget to budget for

• The extractor fan. Building Regulations require adequate mechanical extract in a bathroom, and an old, weak fan is a leading cause of the condensation and black mould we get called out to. Upgrading it while the room is stripped costs a fraction of doing it later.
• Electrical work. Bathrooms are a special location under the wiring regulations, and electrical work there is notifiable under Part P of the Building Regulations in England.
• Floor levelling. If the existing floor isn't flat, large tiles will telegraph every dip. Self-levelling compound or ply overlay is a real line item.
• Making good the ceiling. Downlights, a new fan run and a re-boarded ceiling often go together — worth deciding at quote stage.
• Somewhere to wash. If it's your only bathroom, it will be out of action for most of the job. We stage the work so the WC goes back in as early as possible, but plan for it.

Landlords and letting agents

For rented stock the calculation is different: void days cost more than tile choice. A hard-wearing, standard-spec bathroom fitted in a week beats a designer one fitted in three. We keep a consistent spec across a portfolio so replacements and repairs are quick, and we can run bathroom works alongside other HMO and landlord compliance work or a wider void turnaround in one visit. If a bathroom is failing mid-tenancy rather than between them, it's usually a general repair or emergency job first and a refit later.
