A bathroom renovation in London costs between £6,500 and £16,000 for most homeowners in 2026. A straightforward suite replacement runs £5,000–£7,500. A full redesign with layout changes sits between £9,000–£13,000. A wet room conversion starts around £10,000. Most projects complete in 8–18 days on site. The biggest variable is whether you move the soil pipe. If you keep it where it is, you'll save £1,500–£3,000.
How Much Does a Bathroom Renovation Cost in London in 2026?
London bathroom renovation costs run 15–20% above the UK national average, according to Checkatrade's 2026 cost guide. That's driven by higher labour rates, access and logistics in dense urban areas, and the reality that much of South East London, Prime London, East London, Kent & Essex's housing stock is Victorian or Edwardian properties that regularly turn up surprises once the walls are open.
The national average for a full bathroom renovation sits around £6,600 according to MyJobQuote (2026). Adjusted for London, the realistic baseline for a mid-range family bathroom is £8,000–£9,500 and that's before any layout changes.
| Type of Project | London Cost Range (2026) | Typical Timeline |
|---|---|---|
| Like-for-like suite replacement (same layout) | £5,000 – £7,500 | 5–9 days |
| Standard family bathroom renovation | £7,500 – £12,000 | 9–14 days |
| Ensuite creation or conversion | £6,000 – £10,000 | 8–13 days |
| Wet room installation | £10,000 – £16,000 | 12–18 days |
| Premium / luxury fit-out (bespoke, underfloor heating) | £14,000 – £22,000+ | 14–22 days |
These figures come from our own project data and are cross-referenced against Bathroom Mountain's 2026 guide and NearbyTraders. They're London-specific, not national averages with a percentage tacked on.
What Actually Drives the Cost Up and How to Keep It Down?
Labour is your biggest line item always. According to MyBuilder (2026), labour accounts for 50–60% of a bathroom renovation budget. In London, that means plumbers at £280–£350 per day, tilers at £250–£300, and electricians at £280–£350. A full renovation needs all three, often overlapping.
The second biggest variable is layout change. Moving your soil pipe even just 30cm adds a full day of plumbing. Moving it across the room can add three days. This is where budgets balloon, and it's the first thing we ask about when a homeowner gets in touch. If we can keep the toilet in the same position, we almost always will.
The third factor is what's behind your walls. Victorian and Edwardian terraces make up most of South East London, Prime London, East London, Kent & Essex's housing stock, and they frequently hide old lead pipework, uneven subfloors, and plaster that looks fine until you try to tile over it. Any honest builder will tell you to hold 10–15% of your budget as contingency. Not because something will definitely go wrong but because in a period property, something often does.
How Long Does a Bathroom Renovation Take in London?
Most bathroom renovations in London take between 8 and 16 working days. Checkatrade (2026) puts the range at 5–16 days depending on scope, which matches what we see. Here's a more specific breakdown:
- 5–9 days: Like-for-like replacement. Same layout, new suite, new tiles. Plumber and tiler often overlap, electrician comes in for a day at the end. Low chance of hidden surprises affecting the timeline.
- 9–14 days: Full renovation with some layout changes. Moving the basin or repositioning the shower. Tiler typically needs 3–4 days for full-height tiling. Some plastering likely required.
- 12–18 days: Wet room conversion or a large ensuite with significant replumbing. Screed work, tanking, and full waterproofing all need time to cure before tiling begins. You can't rush this stage.
The most common reason jobs overrun: discoveries made at strip-out. We've found rotten joists, live lead pipework, shower trays that had been leaking into the subfloor for years, and walls that needed complete replastering. We flag everything as soon as we find it and agree a path forward before any additional work starts.
Does a Bathroom Renovation Add Value to a London Home?
It depends on what you're starting with. A bathroom in poor condition is a negotiating point for buyers and a turn-off for renters fixing it removes a problem. Whether it adds value above what you spent is a different question.
According to MyJobQuote (2026), a bathroom renovation typically returns 20–30% of the renovation cost in added property value meaning a £10,000 project might add £2,000–£3,000 to your sale price. The real return is the certainty it gives buyers and the fact that a modernised bathroom removes one of the most common survey red flags. In London's rental market, a well-fitted bathroom reduces void periods and supports higher asking rents.
The honest answer: don't renovate purely to add value. Renovate because you're using it every day and it's not good enough. The value benefit is real but not dramatic.
What Does a Real Bathroom Renovation in South East London, Kent & Essex Look Like?
These are actual jobs we completed. What we've included is exactly what the job involved and what the homeowner started with.
Project 1: Brentwood, Essex
What we did:
This was a full bathroom refurbishment for a client who had just purchased the property and wanted the space completed before moving in. The existing bathroom was in good condition but quite dated and didn’t reflect the standard or style she was looking to achieve.
We carried this out as a full supply and fit project, working closely with the client from the outset to develop the design and make sure everything worked properly within the space before installation began.
The room was fully stripped out and reconfigured to improve both the layout and overall feel. A key feature within this bathroom is the herringbone tiled wall, which creates a strong focal point and adds depth compared to a standard tile layout.
We also formed recessed niches above the toilet with integrated LED lighting, set on a separate circuit so they can be used independently as mood lighting while also serving as a practical storage feature.
The remaining walls were finished in 600x600 tiles to keep the space clean and balanced, with brushed brass fittings used throughout to create a consistent, high-end finish. The overall look leans into a modern traditional style, combining classic detailing with a more contemporary layout.
Attention to detail was a big part of this project, including brushed brass trim edges, consistent finishes across all fixtures, and precise installation throughout to ensure everything aligned properly.
The end result is a complete transformation, turning a dated bathroom into a well-designed, high-quality space that’s ready for the client to move straight into.
Exceptional Bathroom Refurbishment and More!
"I was recommended Buildaway by a colleague as I was impressed by the work they had done
for my
colleague. From the moment I contacted Cormac, I knew I was in good hands. He was
incredibly friendly and accommodating right from the start. The very next day, he was at
my property, taking measurements and discussing design options.
What really
impressed me was Cormac's honesty. He was upfront about what would and wouldn't work
with my space, which was quite tight. I was a bit indecisive, changing my mind several
times, but Cormac remained patient and helped me design and choose materials for my
dream bathroom.
Communication was exceptional throughout the entire project. I
didn't have to worry about a thing, as Cormac and his team effectively project-managed
everything, which was a huge relief since I was mostly away during the project. They
were on-time every day and completed the job in the agreed-upon two weeks.
The
team was respectful of my space and left everything clean after completing the project.
I can't thank them enough! I highly recommend Cormac and the Buildaway team for bathroom
refurbishments and all other building work. They are more than competent and reliable;
you'll be getting the best of the best. Cormac even provided advice and recommendations
for other projects in my house.
Don't hesitate to book Buildaway for your
bathroom refurbs or other building projects you won't regret it!"

Project 2: East Dulwich, London
What we did:
This project involved a full bathroom refurbishment, transforming the existing layout to create a more open, modern, and high-end space. The original room featured a freestanding bath, which was removed to allow for complete reconfiguration and the introduction of a spacious walk-in shower.
We carried out a full strip-out and repositioned key elements including the toilet and vanity unit, with all pipework concealed to achieve a clean, minimal finish throughout.
The room was fully tiled using large-format tiles, with 1200 x 1200 tiles across the floor and 1500 x 600 tiles to the walls. The wall tile sizing was carefully selected to align perfectly with the 1500 x 900 shower tray, allowing for a full, uncut tile across the length of the shower wall. This also enabled us to carry consistent tile lines across the rest of the room, maintaining a clean, symmetrical finish throughout a small detail that makes a big difference in the overall look and feel.
A feature wall was introduced above the vanity area, complemented by an LED mirror and integrated lighting to enhance the space. Additional LED strip lighting was installed along the shower perimeter and across the top of the right-hand wall, creating subtle mood lighting that can be operated independently.
Underfloor heating was installed for added comfort, along with a dual fuel towel rail for year-round practicality. The shower system, basin, and overall installation were designed with concealed fittings to maintain a sleek, high-spec aesthetic.
We also carried out external drainage connections as part of the works, ensuring everything performs as well as it looks.
Finished in a brushed brass specification throughout, this project delivers a refined, high-end bathroom where attention to detail, layout, and lighting all come together seamlessly.
"It was an absolute pleasure working with Cormac and the Buildaway team. Greg is an absolute star. Cormac’s communication and advice was excellent, and the organisation and sourcing of additional materials was brilliant. A truly great team, I would thoroughly recommend Buildaway if you are after a stress free and top quality renovation."

Project 3: Walthamstow, London
What we did:
This project involved a full bathroom refurbishment, upgrading the existing space into a clean, modern finish while keeping a similar overall layout.
We carried out a complete strip-out and rebuild, including constructing a new stud wall to house a concealed shower system and create a built-in niche with integrated LED lighting.
The room was fully tiled throughout, with 1200 x 600 large-format tiles used to form the shower feature wall, and 600 x 600 tiles across the remaining areas to maintain balance and consistency in the space.
A walk-in shower was installed with a minimalist glass screen, alongside upgraded sanitaryware including a Japanese-style toilet, adding a more premium and contemporary feel.
We also made and installed new bespoke doors to bring the overall finish in line with the upgraded design.
In addition to the bathroom works, we carried out further improvements within the property, including full redecoration, installation of a kitchen splashback, fitting of new internal doors, and a new central light in the kitchen.
The result is a modern, well-executed space that combines clean design, practical upgrades, and high-quality detailing throughout.
"I wanted a bathroom refurbishment done and after meeting with several tradesman and decided to go with Buildaway Construction Ltd. From my first contact with Cormac, I was in good hands. His team, turned my vision into reality communicating with me every step of the way and offered helpful suggestions which turned my bathroom into an oasis. I could not be happier and would highly recommend there services. Thank you to the team of Buildaway Construction Ltd"

Project 4: Hackney, London
What we did:
This project involved a full bathroom refurbishment, transforming a dated space into a clean, modern finish while retaining the original layout.
We carried out a complete strip-out and reinstallation, keeping the existing footprint but significantly upgrading the overall look and feel. The room was fully tiled, and all sanitaryware and fittings were updated with a brushed brass finish, giving the space a much more cohesive and premium appearance.
The bath and shower area was modernised with new fixtures, and the overall design was refined to create a more consistent, high-end feel throughout.
We also introduced bespoke storage around the WC area, incorporating slatted panelling and open shelving to add both practicality and a strong design feature.
The result is a complete transformation of the space, achieved through quality finishes, improved detailing, and a clear, modern design direction all without altering the original layout.
"We had an excellent experience working with Buildaway. Cormac was incredibly easy to work with, and gave helpful advice. The finished job was neat, professional and completed efficiently. We'd definitely recommend and would use them again!"

Why Does One Team and One Quote Actually Matter?
Most bathroom renovations don't fall apart because of bad tiles. They fall apart because of coordination failures. You hire a plumber, a tiler, and an electrician separately. They've never worked together. When the plumber runs over, the tiler can't start. The electrician turns up anyway and finds he can't complete his part because the walls aren't ready. You end up as the project manager of people who don't want to be managed, while also holding down a job and living in a house that's half-demolished.
Buildaway's model removes that problem entirely. One quote covers every trade. One project manager coordinates all of them. When something runs over which happens occasionally, this is construction we sort it out. You don't hear about it until there's something worth telling you.
According to MyJobQuote (2026), poor trade coordination is the most common reason bathroom renovations overrun on both time and budget. A single company managing all trades under one contract reduces this risk and removes the homeowner from having to act as site manager during a live build.
What this looks like in practice:
- One fixed-price quote before work starts. No surprise additions mid-project without your sign-off.
- One named project manager you can call. Not a call centre, not a different person each time.
- All trades plumbing, tiling, electrics, plastering coordinated internally. You never have to chase anyone.
- Daily site updates if something changes. Silence if nothing has.
- We work across South East London, Prime London, East London, Kent & Essex. We know the housing stock. We've seen the lead pipes in Victorian terraces and the dodgy floor build-ups in 1930s semis. We quote for the real job, not an idealised version of it.

What Happens After You Submit?
- We respond within 24 hours usually faster. We'll ask a few initial questions about your bathroom and your brief.
- Free site survey one of our project managers visits the bathroom to assess the space, pipework position, access, and anything that might affect the quote.
- Fixed written quote within 48 hours itemised and fixed. Every trade included. No vague "to be confirmed" line items.
- You decide, without pressure if you want to proceed, we agree a start date. If you need time or decide to go elsewhere, that's genuinely fine.
- Build runs to schedule your project manager is on site every day. You'll hear from us when there's something worth knowing.

Do I need planning permission for a bathroom renovation?
In most cases, no. Bathroom renovations are classified as permitted development in the UK and don't require planning permission. However, all electrical work in a bathroom must comply with Part P of the Building Regulations and be carried out by a registered electrician or certified by Building Control. If your property is listed or within a conservation area, additional checks may be needed. For anything uncertain, we advise upfront.
What is the single biggest cost in a bathroom renovation?
Labour by some distance. It accounts for 50–60% of most bathroom renovation budgets according to MyBuilder (2026). In London, daily rates for plumbers, tilers, and electricians range from £250 to £350. Keeping the layout as-is is the most effective way to reduce labour cost. The second most effective is deciding your specification before work starts late changes cost money and time on any live site.
What Should You Know Before Getting Started?
Get the survey right. Any company that quotes for a bathroom renovation without seeing the bathroom or without asking about the pipework layout, the age of the building, the condition of the existing floor is giving you a number they'll want to change later.
Buildaway surveys every job before quoting. We want to find the awkward things before we start, not after. It takes an hour of your time and it means the quote we give you is the one you pay.
If you've been putting your bathroom off whether that's three months or three years it's worth at least getting a survey done. You'll know what it actually involves and what it actually costs. That knowledge is useful regardless of who you end up using.
