What a full bathroom installation actually involves

A full bathroom installation is far more than swapping a suite. It means stripping the room back, dealing with whatever is found behind the old tiles and under the old floor, reworking hot and cold pipework and waste runs to suit the new layout, wiring lighting, extraction and shower supplies to current standards, boarding and plastering, tiling, then fitting sanitaryware, brassware, screens and furniture so every joint is sealed and every surface is level. Four Seasons Bathrooms carries out all of that with one team: Owen McDonagh, a qualified plumber since 1998 holding an NVQ Level 2 in Plumbing, alongside his own electrician and tiler, with a Gas Safe registered engineer brought in when the boiler or gas work requires it.

That single-team structure is the point. Most bathroom projects do not fail on the tiling or the plumbing — they fail in the gaps, where the tiler is waiting on the plumber, the electrician never turns up and a week disappears with nobody answering the phone. When one person prices the job, sequences it and answers the phone throughout, those gaps stop existing. You deal with Owen from the first survey to the final handover.

We work supply-and-fit or labour-only. If you have already chosen your suite, tiles and brassware, we will fit them. If you would rather we handled the sourcing and specification, we will do that instead. Either way the room is quoted at a fixed price after we have physically seen it, with the honest caveat that genuinely unforeseen problems behind walls and floors can affect the final figure. Quotes are free, and card and bank transfer are both accepted.

Who this is for

Homeowners replacing a tired bathroom

Rooms fitted twenty or thirty years ago, where the suite still works but the tiling, sealant and layout have run out of life. We strip back to sound substrate and rebuild rather than tiling over old problems.

Buyers renovating a newly bought house

Bathrooms and en-suites brought up to standard before you move in, sequenced so the messiest work happens while the house is empty.

Families changing how the room works

Bath swapped for a walk-in shower, an airing cupboard absorbed to gain floor area, a separate WC opened into the main room, or a second bathroom formed from a spare bedroom.

Landlords and letting properties

Durable, straightforward specifications that survive tenants, with the plumbing and electrics documented and guaranteed.

What happens when a bathroom is fitted badly

A bathroom is one of the few rooms in a house where poor work stays hidden and then bills you years later. Water finds every shortcut. A shower tray bedded on packers instead of a solid base flexes with each use until the silicone joint splits, and the water goes into the floor rather than the waste. Tiles fixed to unprimed plasterboard behind a shower delaminate quietly, and the first symptom is a stain on the ceiling below. A waste run laid without adequate fall holds standing water, smells, then blocks. None of these show up in the handover photographs.

The financial escalation is the part homeowners underestimate. A failed seal that could have been prevented at first fix turns into replaced floorboards, a re-plastered ceiling, redecoration in the room below and, in the worst cases, an insurance claim with an excess and a raised premium. Where the leak sits near a lighting circuit, it stops being a repair problem and becomes a safety problem. Ripping out tiling to reach a pipe that was buried without an access point can cost more than the pipework itself.

There is also a cost in lost time. A bathroom booked as a two-week job that drifts to eight weeks because trades will not co-ordinate leaves a household sharing one basin, showering elsewhere and losing evenings to phone calls. We price a realistic timescale in writing with the quote rather than an optimistic one over the phone, because a date you can plan around is part of the job.

Common mistakes we are called in to fix

  • Choosing on price alone and accepting a verbal figure with no written scope, so every extra becomes an argument mid-job.
  • Tiling over existing tiles or unsound plaster to save a day, which transfers every underlying defect to the new surface.
  • Skipping tanking behind showers and in wet areas because standard boards look waterproof when they are not.
  • Leaving electrics to a general builder rather than a qualified electrician working to bathroom zone requirements.
  • Buying a suite before the room is measured and the layout resolved, then paying to force it into a space it does not fit.
  • Burying isolation valves and pipework with no access, guaranteeing destructive work at the first repair.

How the job runs

01

Free survey and measure

We visit the actual room, measure it properly, look at the existing pipework, waste positions, floor construction and consumer unit, and listen to how you want to use the space. No sales pitch and no obligation.

02

Fixed-price quote and written timescale

You receive one price for the whole job, supply-and-fit or labour-only, with the scope set out and a realistic start date and duration, so the number is known before anyone lifts a tool.

03

Strip-out and first fix

The old room comes out, waste is removed, and pipework, waste runs and electrical circuits are set out for the new layout. Anything unexpected behind the walls is shown to you and priced before it is done.

04

Boarding, tanking, plastering and tiling

Wet areas are boarded and tanked, walls are made flat and plastered where needed, then our own tiler sets out the tiling so cuts fall where they should and grout lines run true.

05

Second fix, testing and handover

Sanitaryware, brassware, screens, lighting and extraction are fitted, everything is run and tested for leaks and correct drainage, the room is cleaned, and controls are demonstrated. Guarantee runs from that day: one year on plumbing and parts, two years on tiling.

What you actually get

One price, agreed up front

The fixed price is set after we have seen the room, not estimated from a photograph, so the budget you plan around is the budget you pay.

No dead weeks between trades

Plumbing, electrics, plastering and tiling sit inside one team and one schedule, which is why our jobs finish in a run rather than in instalments.

Built to stay dry

Correct falls, tanked wet areas, properly supported trays and sealed junctions — the details that decide whether a bathroom lasts fifteen years or leaks in two.

Workmanship guaranteed in writing

One year on plumbing and parts, two years on tiling, backed by £2 million public liability insurance and a Which? Trusted Trader endorsement.

One person answering the phone

Owen runs every job himself. Questions during the work, and anything afterwards, go to the person who did the pricing rather than into a call queue.

A track record you can check

9.83 out of 10 across 172 Checkatrade reviews, five stars on Rated People and no bad reviews in seven years of trading — all publicly verifiable before you commit.

Specification, materials and methods

Two bathrooms of the same size can be built to entirely different standards. These are the decisions that separate them, and how we approach each one on installations across Ampthill, Flitwick, Bedford and the surrounding Bedfordshire towns.

Substrates, boarding and tanking

Wet areas are boarded with a suitable tile backer rather than standard plasterboard, then tanked with a liquid membrane and reinforcing tape at internal corners and pipe penetrations. Dry zones can be plastered and primed conventionally. Getting the substrate right is the single biggest factor in whether tiling survives, because a tile is only as sound as what it is bonded to.

Showers, trays and enclosures

Low-profile stone resin trays, standard acrylic trays and tiled formers all behave differently. Trays are bedded solid so there is no flex, upstands and seals are formed in the correct order, and enclosure fixings are made into supported substrate. Mixer showers, electric showers and thermostatic bar valves are chosen against the property's water pressure and system type rather than the picture in the brochure.

Pipework, waste and access

Hot and cold runs are re-set for the new layout, isolation valves are fitted where they can actually be reached, and waste runs are laid with proper fall to prevent standing water and smells. Where pipework has to be concealed, we leave sensible access rather than sealing in a future repair.

Tiling, layouts and grout

Large-format porcelain, ceramic, mosaic and natural stone each need different setting out, adhesive and support. Our own tiler sets out from the most visible line so awkward cuts land where the eye does not go, uses the correct adhesive bed for the format, and finishes with grout and flexible sealant appropriate to the movement in the junction. Tiling carries a two-year guarantee.

Lighting, extraction and electrical zones

Bathroom electrics are wired by our qualified electrician working to the zone requirements that govern what fitting can go where. Downlights, mirror lighting, shaver sockets, underfloor heating and extraction are planned at first fix, and extraction is sized for the room so moisture leaves the building rather than settling into the plaster.

Small rooms, en-suites, cloakrooms and loft conversions

Compact spaces need short waste runs, doors that clear the sanitaryware and sensible pump or macerator decisions where gravity drainage is not available. En-suites above living rooms get particular attention on waterproofing and pipe noise. Loft and cloakroom installations are planned around joist runs and existing soil stack positions before anything is bought.

Family homes, rentals and older properties

A family bathroom takes hard daily use and benefits from robust surfaces and serviceable fittings. Rental properties need durable, replaceable specifications. Period and older Bedfordshire houses often hide lath and plaster, uneven floors and previous DIY plumbing, which is exactly why we survey in person and price honestly rather than assuming a standard build-up.

Common questions

Anything not covered here, call Owen McDonagh on 07533 646033 and ask. Quotes are free and the phone is monitored 24/7.

How much does a new bathroom cost in Ampthill?
Bathrooms are quoted at a fixed price once we have seen the room, because the price depends on the size, the layout changes, the state of what is behind the tiles and the specification you choose. Quotes are free and the only caveat on the fixed price is genuinely unforeseen issues behind walls or floors. Smaller pieces of work are charged at an hourly rate, typically £60 per hour depending on the job.
How long does a full bathroom installation take?
It depends on the size of the room and how much changes behind the tiles. Rather than quote an optimistic number on the phone, we give you a realistic timescale in writing alongside the fixed price after the survey, and because plumbing, electrics and tiling are all our own team the work runs continuously instead of stopping between trades.
Do you supply the bathroom or can I buy my own?
Either works. We offer supply and fit, or labour-only if you have already chosen and bought your suite, tiles and brassware. If you are buying yourself, talk to us before you order so we can check the items suit the room, the water pressure and the layout.
Who actually carries out the work in my house?
Owen McDonagh and his own team. That includes a qualified electrician, a tiler and a Gas Safe registered engineer called on as needed. Every subcontractor is vetted and Which? endorsed — your home is not handed to whoever happens to be free that week.
Is the work guaranteed?
Yes. Workmanship is guaranteed for one year on parts and plumbing and two years on tiling, and we carry £2 million public liability insurance. We are Checkatrade members with a 9.83 out of 10 score across 172 reviews and a Which? Trusted Trader endorsement.
Can I use the bathroom while the work is going on?
For most of a full refit the room is out of use, which is why the sequence matters. We tell you at the survey which days the room will be unavailable so you can plan, and we do not strip a room out and then leave it.
Can you move the bath, WC or shower to a different position?
Usually yes. Moving sanitaryware means re-routing waste with correct fall and re-setting hot and cold supplies, which we assess at the survey. Where a position is not practical because of the soil stack or floor construction, we will tell you before you commit rather than after.
What happens if you find something unexpected behind the walls?
We show you, explain the options and price the extra work before doing it. Old properties around Bedfordshire regularly hide previous DIY plumbing, rotten timber or failed waterproofing, and the honest approach is to deal with it properly rather than tile over it.
Do you cover emergencies once the bathroom is fitted?
Yes. Emergency cover runs 24/7 for leaks, drainage problems and loss of water, charged at £120 per hour, and the phone is always monitored. Existing customers always get an answer.
Which areas do you install bathrooms in?
Ampthill, Flitwick, Bedford, Luton, Dunstable, Milton Keynes, Hitchin, Harpenden, St Albans and the surrounding Bedfordshire and Hertfordshire villages. If your town is not listed, call and ask.
