In many Hammersmith and Fulham terraces, the family bathroom is in the same place it was a century ago: at the back of the first floor, in the outrigger over the kitchen. It’s often cold, a bit small, and the one room everyone in the house queues for.
A bathroom renovation is one of the most common projects in the borough. Some homeowners simply replace a tired suite. Others rework the layout, add an en-suite in a new loft, or turn a small bathroom into a walk-in shower room or wet room.
In the borough’s mansion flats, a new bathroom also means dealing with the freeholder, the lease and the flat below. Water and noise travel, and most blocks have rules about both.
This guide covers bathroom renovation costs in Hammersmith and Fulham, the types of projects, what to expect in period homes and mansion flats, waterproofing, regulations, timings and how to find a vetted specialist.
Bathroom renovation costs in Hammersmith and Fulham
Bathroom renovation costs in Hammersmith and Fulham range from around £4,500 for a basic re-suite and retile to £35,000 or more for a high-specification wet room on an upper floor. The size of the room, the tiles and sanitaryware you choose, and whether the layout or the floor structure changes make the biggest difference.
Labour and access costs in the borough run above the London average. Parsons Green, Hurlingham and Brook Green, where clients often choose natural stone and designer brassware, usually run another 10-20% above these figures.
| Project type | Typical cost (Hammersmith & Fulham) | Parsons Green, Hurlingham & Brook Green |
|---|---|---|
| Basic re-suite and retile | £4,500-£9,000 | Add 10-20% |
| Mid-range full renovation | £9,000-£18,000 | Add 10-20% |
| High-spec full renovation | £18,000-£35,000 | Add 10-20% |
| Loft en-suite (shower only) | £9,000-£17,000 | Add 10-20% |
| Full en-suite (shower and bath) | £15,000-£27,000 | Add 10-20% |
| Wet room (ground floor, solid floor) | £13,000-£24,000 | Add 10-20% |
| Wet room (upper floor, timber joists) | £20,000-£35,000 | Add 10-20% |
| Mansion flat bathroom | £12,000-£28,000 | Add 10-20% |
These prices include stripping out, first-fix plumbing and electrics, boarding, waterproofing, tiling, sanitaryware fitting and second fix. Sanitaryware, tiles and brassware vary widely in price, so check what each quote allows for. In a mansion flat, also budget for the freeholder’s licence and surveyor’s fees.
Types of bathroom renovation
Re-suite and retile
New bath or shower, basin, toilet and tiles in the same layout. It’s the quickest and cheapest option, and it suits a bathroom where the pipework and floor are in good condition.
Full bathroom renovation
The room is stripped back to the walls and floor joists. Pipework, wiring, ventilation and boarding are replaced; the layout can change, and the room is fully waterproofed before tiling. In a period terrace, it’s the right choice if the bathroom hasn’t been touched for 20 years or more.
En-suite in a loft conversion
Adding a shower room in a new loft is one of the most popular projects in the borough. The key question is drainage: a gravity connection to the existing soil stack is best, so the en-suite is usually placed above or close to the bathroom below. Where that isn’t possible, a pumped system works but needs servicing. See our guide to loft conversions in Hammersmith →
Wet Room
A level-access shower with no tray, where the whole floor is waterproofed and falls gently to a drain. On a solid ground floor, it’s straightforward. On an upper floor with timber joists, the floor has to be strengthened and set to a fall, and the waterproofing must be done carefully, which is why it costs more.
Bathrooms in Victorian and Edwardian terraces
The outrigger bathroom
In most of the borough’s terraces, the bathroom sits in the rear outrigger above the kitchen. These rooms have three outside walls, so they lose heat quickly. A renovation is the moment to insulate the walls, fit a better window, and add underfloor heating or a heated towel rail.
Timber floors
Suspended timber floors flex, which can crack tiles and grout. Your specialist should check the joists, strengthen any that are notched or rotten, and use a stiff tile backer board before tiling. Joists cut for old pipework are very common.
Soil stacks and drainage
Many terraces still have cast-iron soil stacks on the outside wall. They often work well, but check the joints and replace any cracked sections while the bathroom is open. Old lead supply pipes should be replaced at the same time.
Ventilation
Building Regulations require an extractor fan in a bathroom. It should extract at least 15 litres per second. Good ventilation is the best defence against mould in a cold outrigger bathroom.
Bathrooms in mansion flats
If you own a leasehold flat in a mansion block in Barons Court, West Kensington or Fulham, read your lease before planning anything.
- Licence to alter: most leases need the freeholder’s written consent to move a bathroom, change the waste route or add a wet room. Allow 4-8 weeks, and budget for their surveyor’s fees.
- Water leaks: a leak into the flat below is the biggest risk. Insist on a tanked floor and walls, and a flood test before tiling.
- Floors: many leases require acoustic underlay or limit hard flooring, which affects tile choice.
- Shared stacks: bathrooms usually connect to a shared soil stack, which limits where you can move fittings.
- Working hours: most blocks restrict noisy work, and some require a method statement before work starts.
Most bathroom renovations don’t need planning permission or a Building Control application. The rules that do apply are:
- Electrical work in a bathroom must meet the wiring regulations and be done by a registered electrician who certifies it
- A new or relocated toilet, shower or soil connection must meet the drainage requirements of the Building Regulations
- A new bathroom where there wasn’t one before, such as a loft en-suite, is part of the Building Regulations approval for that project
- Extractor fans are required, with minimum extraction rates
- A Gas Safe registered engineer must do gas boiler work
- In a listed building, changes may need Listed Building Consent
A new window in a flat, or a window replacement where an Article 4 Direction applies, may need planning permission.

How to pay for your bathroom renovation
Every QuoteMyRenovation builder agrees to milestone payments. A typical schedule is a 10% deposit, then payments when the strip-out and first fix are complete, when waterproofing and boarding are done, when the tiling is complete, and when the sanitaryware is fitted and second fix is finished, with 5% held back until any snags are fixed. We check in with you before each payment. See how milestone payments work →Â
