Bathroom Installation in Croydon
A bathroom is the one room where hidden plumbing mistakes show up as stains on a ceiling. [Proper Plumber Croydon](/) arranges bathroom installation through independently owned local partner companies on 07898 116196, and the plumbing is treated as the structure of the job: supply, waste and falls are settled first, and the tiles and the suite come after.
Published Croydon figures put a full bathroom installation at about £5,175 to £13,800, with a typical job near £9,500. A basic like-for-like refit sits towards £5,175 to £7,500, a standard bathroom with new tiling and fittings around £7,500 to £10,350, and a complex wet room from £10,350 upwards. These are published ranges, not our quotes, and the partner company prices your room in writing after seeing it.
Croydon's housing shapes the work. A Victorian terrace in Addiscombe or Woodside has a timber floor, a waste that may run through the wall to an outside stack, and often a bathroom added later over the back kitchen, so joists and falls need checking before a heavier bath or a tiled floor goes in. A flat near East Croydon may share a riser and a lease that requires permission for noisy work.
Hard water is the other local fact. At 308 mg/l as calcium carbonate, Croydon East supply scales shower valves, taps and heaters quickly. Choosing fittings that can be descaled and fitting an isolation valve to each appliance keeps the next repair small.
A bathroom can be done in one planned stretch rather than a series of surprises, and the written quote is where that planning shows up.

What We Do
What Goes Into a Bathroom Installation
Four trades touch a bathroom, and the plumbing sets the order for the rest.
Strip-Out and Making Safe
The old suite comes out, the supplies are isolated and capped, and the walls and floor are checked for damp, rot or old leaks before anything new is fixed. In a Victorian house this is when a rotten joist or a failing lead run is found and priced, not left for later.
First-Fix Plumbing and Waste
New supply pipes, waste runs and any electric shower or boiler feed are positioned before the walls are closed. Wastes need the right fall and pipe size under Building Regulations Part H, and supplies use WRAS-approved fittings in line with the Water Supply (Water Fittings) Regulations 1999.
Second-Fix, Fittings and Commissioning
Once the tiling is done the bath, basin, toilet and shower are connected, tested for leaks and balanced for temperature and flow. Every appliance should have its own isolation valve, and a shower fitted to a hard-water supply should be easy to descale.
The Benefits
Why Planning the Plumbing First Pays
Most bathroom overruns come from decisions made after the walls are closed.
A Layout That Fits the Pipes
Moving a toilet costs more than leaving it, because the soil pipe needs a fall and a route. The partner company explains what moving each item would add, so the layout matches your budget rather than a catalogue picture.
A Written Quote With Provisional Sums Named
Tiling, electrics and decorating may be separate trades. A good quote states what is included, what is a provisional sum and who is responsible for each stage, so there are no surprises on the final invoice.
A Waterproof Result
Wet rooms and showers need properly tanked surfaces and falls to the drain. The partner company builds to the manufacturer's instructions for the tanking system, and you should be shown the pressure test before the tiles go on.
Good to Know
Before You Commit to a Bathroom
Settling these early keeps the quote steady.
Questions the Quote Should Answer
Ask for these in writing.
- Which fittings and brands are included
- Whether moving any appliance is priced
- Who handles tiling, electrics and making good
- How long the room will be out of use
- What happens if hidden damp or rot is found
Plumbing Decisions Worth Making Early
These are hard to change later.
- Shower type, mixer or electric, and flow needed
- Position of the toilet and its soil pipe
- Isolation valves on every appliance
- Underfloor heating or heated towel rail
- Access panel to the bath or shower valve
Why Us
Bathrooms Across Addiscombe, Woodside and Shirley
The same plumbing standard whichever house the bathroom sits in.
Victorian Floors and Awkward Waste
Addiscombe and Woodside terraces often have a back-addition bathroom with a long, shallow waste run. The partner company checks falls and the route to the stack before quoting, because a bathroom that looks perfect and drains slowly is not finished.
Flats and Shared Risers
Around East Croydon and Cherry Orchard Road, flat blocks mean shared stacks, building rules and neighbours below. The partner company asks about the lease and access first, so the job starts on a day that suits the block.
One Number, a Named Company
Before anyone arrives we text you the name of the partner company. They quote, carry out the work, invoice and take payment directly. If something is wrong afterwards, ring us and we chase it.
A bathroom refit often goes alongside a toilet repair or replacement, and a new shower can change what the home's hot-water supply needs, which is where boiler installation or hot water cylinder repair comes in. If an old bathroom has been leaking, leak detection and repair can find the source before the strip-out. We work in Addiscombe, South Norwood and Shirley. See all services.
What Bathroom Installation Includes
Bathroom installation is the removal of an existing bathroom, or the creation of a new one, and the fitting of a bath or shower, basin, toilet and associated pipework, waste, tiling and finishes. The plumbing is the part that has to be right first time, because it ends up behind tiles and boards.
Supply pipework follows the Water Supply (Water Fittings) Regulations 1999 and BS EN 806, and drainage follows Part H of the Building Regulations. Croydon Council's building control department is the local authority if a job needs notification.
What Affects the Price of a Bathroom
Size, Layout and Specification
A small room with every appliance in its present position is the cheapest route. Moving the toilet, adding a wet room or choosing premium fittings and large-format tiles raises the total.
What the Strip-Out Reveals
Old pipework, rotten joists and damp walls are priced when they are found. Ask for any extra work in writing before it begins, so the final invoice matches what was agreed.
Staging the Work Sensibly
Hot Water During the Job
A bathroom refit often means the water is off for part of a day and the shower unavailable for several. Planning an alternative, such as a neighbour's shower or a gym membership, makes the week less stressful, and the partner company should tell you in advance when each stage takes the water off.
Choosing Fittings That Last
Basin taps with ceramic cartridges, thermostatic shower valves with accessible filters and wall-hung toilets with a serviceable concealed cistern all reduce future repair bills. Ask what is behind the panel and whether it can be reached without breaking tiles.
Making Good Afterwards
Plaster, paint and flooring around new pipework are part of the result you see. The quote should say who does that work, so the bathroom is finished rather than merely plumbed.
Costs You Should See Written Down
Provisional Sums
Tiling, electrics and decorating are sometimes shown as provisional sums until the room is opened up. Ask what each figure assumes, and what triggers a change, so a surprise is an explained line and not a dispute.
Waste, Rubbish and Protection
Strip-out creates old porcelain, tiles and plaster, and a family home needs the stairs and hallway protected. Confirm in the quote that removal of waste and protection of floors are included, because they are easy to leave out and expensive to add afterwards.
Frequently Asked Questions
How much does a bathroom installation cost in Croydon?
Published Croydon ranges run from about £5,175 to £13,800, with a typical job near £9,500. A basic refit sits toward the lower end, a standard bathroom with new tiling in the middle, and a complex wet room above £10,350. These are published figures, not our quotes, and the partner company prices your room in writing after a visit.
How long does a bathroom installation take?
A straightforward refit often takes one to two weeks, and a wet room or a layout change can take longer because of tanking, drying times and tiling. The quote should give the expected duration and say when the water will be off. Hidden damp or rotten joists found during strip-out can add time, which is why the partner company inspects before fixing anything new.
Can I move the toilet or shower to a different wall?
Often yes, but it costs more than leaving them in place. A toilet needs a soil pipe with a fall to the stack, and a shower needs a waste with enough gradient. Building Regulations Part H governs drainage, so the partner company checks the route in a terrace or flat before quoting the move. Ask for the price of the move as its own line, so you can choose to leave it where it is.
Do I need a wet room, or will a shower tray do?
A tray is cheaper and simpler, and it suits most bathrooms. A wet room costs more because the whole floor has to be tanked and sloped to the drain, and it needs a sound floor. In a Victorian timber-floored terrace, the partner company checks the joists before recommending one. The quote should show both options, so you can compare the cost of each before deciding.
What rules does bathroom plumbing have to follow?
Supply pipework and fittings must comply with the Water Supply (Water Fittings) Regulations 1999, which is why WRAS-approved products are used. Waste and drainage follow Part H of the Building Regulations. Any new hot-water or heating changes may also touch Part G and Part L, and the partner company says in the quote which apply.
Does hard water affect my choice of shower and taps?
Yes. Croydon East water measured 308 mg/l as calcium carbonate in 2025, which is very hard, so scale clogs shower heads, thermostatic cartridges and mixer taps. Ask for fittings that can be descaled and for isolation valves on each appliance, so a future repair does not mean shutting off the whole house. Descaling a shower head every few months also keeps the flow strong and the spray pattern even.
Will you handle the tiling and electrics too?
The partner company will say who does what in the quote. Some run the whole project, including tiling and electrics, while others handle the plumbing and a coordinating contractor does the rest. Ask for the split in writing so you know who is responsible for each stage and who to ring if something needs putting right.
Do I need permission to refit a bathroom in a flat?
Often yes. Many leases require consent from the freeholder or management company for work that affects pipes, floors or noise, and shared stacks mean neighbours are affected. Check your lease before the date is fixed, and tell the partner company about access restrictions and working hours at the outset. A short email to the managing agent before the date is fixed usually avoids delays and awkward conversations later.
What happens if damp or rot is found when the old bathroom is stripped out?
It is dealt with before anything new is fitted. The partner company shows you what has been found, explains the repair and gives a written price for the extra work. Never accept a verbal figure for hidden damage; the written quote is the record of what was agreed. If the extra work is substantial, you can pause, compare it with another view and then decide how to proceed.
Can you install a bathroom at short notice?
A full bathroom needs surveying, ordering and scheduling, so it is a planned job rather than an emergency one. If a bathroom leak or burst forces the issue, we can arrange an urgent visit to make things safe first, and the refit follows once the partner company has surveyed and quoted. Ring us and we will pass the survey request to the partner company who can look soonest, and they will agree dates with you in writing.
Will the new bathroom come with a guarantee?
Fittings carry the manufacturer's guarantee, and the workmanship terms come from the partner company. Ask for both in the quote and keep the paperwork. If a leak appears later, ring us and we chase the partner company to put it right. Ask for the guarantee terms to be written on the quote, so you know exactly what is covered and for how long.
