Bathroom Renovation Crawley
Bathrooms in Crawley tend to fail the same way. Not the tiling. The stuff behind it. A bathroom renovation Crawley homeowners plan starts from a room built to a tight brief, with a hot water cylinder in a cupboard beside the bathroom and a fan that was never really up to the job.

Sixty-odd years on, people want a walk-in shower, decent pressure, and somewhere to put a towel. Getting there usually means dealing with services first and choosing taps second.
Compare Builders puts homeowners in front of verified bathroom fitters Crawley wide, and gives those firms a clean route to the work. Describe the job once, pick who quotes, and nobody buys your phone number.
Bathroom renovation Crawley: what you are working with
Three things shape almost every bathroom renovation Crawley homeowners take on.
The cylinder. A lot of the original stock still has a vented hot-water cylinder in an airing cupboard, either next to or inside the bathroom. It is the largest single-space opportunity in the room and also the thing most likely to complicate the job.
Flow, not pressure. Older houses here were plumbed for gravity feed from a loft tank. Rainfall heads and body jets assume a very different form. Ask for a flow rate test at the start, in litres per minute, rather than taking anyone's word that the shower will be fine.
The soil stack. Early neighbourhoods generally have the stack outside on the back wall. Later stock boxes it in internally. Which one you have decides how far a WC can move without either a macerator or a rerouted gravity run.
The airing cupboard question
Reclaiming that cupboard is the most common way to find space without touching a wall, and it comes with a decision attached.
Take the cylinder out, and you are either going to a combi boiler or to an unvented cylinder somewhere else in the house. A combi is simpler and frees the loft tank, too, but it draws hot water at a rate tied to the incoming main pressure, which is exactly why the flow rate test matters. An unvented cylinder maintains a strong simultaneous flow to two outlets but requires space, a safe discharge route, and an annual service by someone qualified to work on it.
Neither is wrong. They lead to different bathrooms, and the choice needs to be made before anyone orders a shower.
Wet rooms on a timber first floor
Most Crawley bathrooms are upstairs on timber joists, which changes what a wet room involves.
You need a fall to the gully, and on a timber floor that means one of two approaches. Either the former is recessed between the joists, which requires a structural review of what is being cut and where, or the floor is built up and you accept a threshold at the door. Builders will have a preference. Ask which they are proposing and why, because it affects both the finished look and how much of the room you lose.
Tanking then has to be continuous, taken up the walls to the required height, and properly detailed at every corner and pipe penetration. Tile and grout on their own hold nothing back.

Ventilation rules have moved
Worth knowing before you replace a bathroom window.
Part F was tightened in 2021, and one practical consequence is that replacement windows generally have to maintain at least the background ventilation that was there before. Rip out an old window with trickle vents and fit a replacement without them, and you have made the room worse and the work non-compliant at the same time.
The mechanical extract still has to be ducted to the outside and sized for the room. A humidistat fan with an overrun timer is a small upgrade that solves most of the mould complaints people have in these houses.
How Compare Builders matches you with bathroom fitters Crawley wide
About a week from start to appointment.
You complete a short enquiry: scope, budget bracket, timings, postcode, and photographs if you have them. A code goes to your mobile so firms know it is a real enquiry rather than a tyre kick.
The Cost Planner gives you an indicative budget range. It is a planning figure, not a quotation, but it means you are not guessing.
Verified firms covering RH postcodes are then invited in waves. The bathroom fitters Crawley wide who want the job opt in. You see up to six of them ranked openly by Trust Portfolio, and you choose three to quote. The only firm that pays anything is the one you appoint.
The eight checks behind every bathroom fitters Crawley shortlist
Reviews can be bought, so we check the source instead. Before a firm reaches you at all:
- Companies House registration, confirmed rather than claimed
- Public liability insurance of at least £2m, with the certificate checked and expiry tracked
- VAT registration where it applies
- Trade body membership, checked with the trade body itself
- Portfolio and reputation reviewed
- Right to work confirmed
- Photo ID with liveness detection on the principal
- Financial standing assessed
Clear all eight, and the firm holds a public verification record you can read before anyone visits. Every check: the insurer, the cover level, the full history. Redone annually, and failures are suspended.
Above that gate sits the Trust Portfolio: verification depth, vetted photographs and video of finished work, reviews, track record. Paying for a higher tier doesn't move anyone up it.
One thing to ask separately. If an unvented cylinder is going in, the installer needs the relevant qualification, and that is a fair question to put to any bathroom fitters Crawley homeowners are considering.
Sign-off and building control
More of a bathroom is notifiable than people expect.
Electrical work falls under Part P and is subject to zone requirements around the bath and shower. Ventilation sits under Part F. Hot water safety and unvented systems fall under Part G, which is where an unvented cylinder brings its own competent person requirement. Drainage changes engage Part H. Taking out a wall brings in Part A if it carries load.
Sign-off goes through Crawley Borough Council building control or a registered building control approver.
What sets the price of a bathroom renovation Crawley homeowners plan
Sanitaryware is the visible spend and rarely the deciding one.
The variables that affect a bathroom renovation Crawley quotation are whether the WC and soil connection stay put, what happens to the cylinder, whether the floor is being recessed or built up, and how far the extract has to travel. Underfloor heating adds screed and drying time to the programme.
Then the boring ones that get missed. Making good the ceiling below after pipework changes. Replacing the loft tank arrangement if you go combi. Removing and reinstating the airing cupboard structure.
Get all three firms itemising the same specification, and put the variations procedure in writing before anyone starts. On a bathroom renovation Crawley budgets come apart on changes, not on the opening figure.
For bathroom fitters Crawley based
For bathroom fitters Crawley based, it is simple enough. See the job, see the fee, pay only if you win.
Before committing anything, you get the project overview, estimated value, area, timescale, and the exact Project Fee payable if it is yours. Looking costs nothing; registering interest costs nothing.
Fees are credited to your account. When the homeowner picks their three, the fee is reserved from each rather than taken. Whoever is appointed has theirs converted; the other two are released in full. If the homeowner pulls out, everything is released. And where the signed contract lands materially below the Cost Planner value, the fee comes down. Never up.
Verification comes with every Compare Builders tier. Subscription tier does not affect ranking. Tiers control the value of the work you can access and which services come with it. Position comes from your Trust Portfolio. Details on the builders page.
The end of paying for leads you’ll never win.
No leads sold to five rivals. Get verified, see real jobs in your area, and register interest only in the ones you want. Only pay when you win the work. Nothing wasted.

Frequently asked questions
Is a wet room a sensible idea upstairs?
It can be, but it needs to be designed rather than assumed. On a timber first floor you either recess a former between the joists, which needs a structural check, or build the floor up and accept a threshold at the door. Tanking has to be continuous either way.
Do I have to keep trickle vents if I replace the bathroom window?
Generally yes. Since Part F was tightened in 2021, replacement windows are expected to maintain at least the same background ventilation as before. Removing trickle vents from an older frame and fitting a replacement without them creates a compliance problem and a condensation one at the same time.
Can I take out the airing cupboard to gain space?
Usually, though, it forces a hot water decision first. You either switch to a combi boiler or have an unvented cylinder installed elsewhere in the house, and each behaves differently when two outlets run at once. Settle that before specifying a shower rather than afterward.
How do I know the shower will be powerful enough?
Ask for a flow rate measurement in litres per minute before anything is specified. Gravity-fed systems, common in older Crawley housing, deliver far less than rainfall heads assume, and the answer may be a pump, a combi, or a different shower.
Is there any help towards an accessible bathroom?
Possibly. Disabled Facilities Grants are administered by the local council for adaptations such as level-access showers, subject to assessment and means testing. Approach Crawley Borough Council early, as approval must come before the work starts, not after.
As a builder, how many projects will I see?
That depends on your trade, tier and coverage area. Projects go to a matched pool and are released in waves rather than blasted out to everyone, so the invitations you receive are ones you plausibly fit. You then opt into whichever are worth your time.
