A bathroom installation replaces your old suite with new sanitaryware, a bath or shower, tiling and fittings, including the plumbing, electrics, ventilation and waterproofing needed for a complete, watertight room.
Our guide for a new bathroom in the East of England comes to £5,200–£12,500 with VAT added, and that range applies across Hertfordshire, including Watford, Hemel Hempstead, Stevenage and St Albans. Your own price depends on the size of the job, the specification and how easy it is to work on the site. We survey for free, check any consents needed under the rules in England, and then put the price in writing.

Housing across Hertfordshire
Hertfordshire is home to the first garden cities, Letchworth and Welwyn Garden City, and the post-war new towns of Stevenage, Hatfield and Hemel Hempstead. Watford and St Albans have Victorian terraces and Georgian streets, interwar semis line the commuter suburbs, and brick-and-flint cottages appear in Chiltern villages to the west.
New-town and garden-city homes often suit extensions, window replacement and roofline renewal, though some garden-city estates have their own design guidance. Victorian terraces commonly take loft rooms and side-return extensions.
Generally dry with chalk and clay soils; clay areas can move in long dry spells, and mature trees near houses need considering for foundations.
Do you need permission in Hertfordshire?
As Hertfordshire is in England, read the following with that system of planning and building control in mind. We check what applies to your house with the council before you receive a quote.
Internal work such as a new kitchen, bathroom, flooring, plastering or decorating does not need planning permission in England, unless the house is listed, when listed building consent may be needed even for internal changes.
Some internal work is covered by Building Regulations: new electrical circuits and work in bathrooms (Part P), new drainage, structural changes, extractor ventilation and any new window. Notifiable work is certified by a registered installer or by building control.
Rules change and every property is different, so we check the planning history and constraints for your address before we quote.
From survey to handover
We look at the job
We begin by looking at the job in person. During the free survey we discuss options, materials and budget for a new bathroom, and photograph or measure anything the quote needs to reflect.
Your fixed price
Next you receive a written quote with a fixed price for the agreed specification. It lists what is included, what is not, and how payments are staged, so you can compare it properly.
Dates and permissions
Before anyone starts, we confirm the programme in writing, check whether consents are required and arrange deliveries. If a skip or scaffolding on the road needs a permit, we apply for it.
On site to finish
On site, the agreed plan is followed and any change is put in writing first. At completion we do a final clean, go through the snagging list with you and leave you with the relevant documents.
How we work
Frequently asked questions
How much does a new bathroom cost?
A typical family bathroom costs £5,200–£12,500 supplied and fitted, including tiling, a new suite, shower, lighting and an extractor fan. Shower rooms and simple en-suites cost a little less, while wet rooms, standalone baths and large-format tiles cost more. Moving the toilet or replacing rotten floorboards adds to the total. We confirm a fixed price for the agreed specification after the survey.
How long does it take to fit a bathroom?
Fitting a typical bathroom takes one to two weeks on site. Strip-out and first-fix plumbing and electrics come first, followed by any plastering or boarding, waterproofing, tiling and then the suite, taps and fittings. Wet rooms and rooms with underfloor heating take longer because screeds and waterproofing need time to cure. We give you a day-by-day plan before work starts.
Who do I deal with during the job?
One point of contact manages your project from survey to handover. They schedule the trades working under our contract, keep you updated on progress, and are the person to call with any question. You don't need to coordinate builders, electricians or decorators separately, because that is part of what we do.
Which tiles are easiest to keep clean?
Large-format porcelain tiles are usually easiest to keep clean, because there are fewer grout lines to collect dirt and porcelain absorbs very little water. Glossy tiles show water marks more than matt ones, while textured floor tiles give better grip. Grout colour matters too: mid-grey hides staining better than white. We can suggest anti-slip ratings and grout options that suit how you use the room.
Which postcodes in Hertfordshire do you cover?
We cover WD1, HP1, SG1 and AL1, along with the rest of Hertfordshire. If your postcode is not listed, get in touch anyway: our coverage is UK-wide, and we can usually arrange a survey wherever you live. Enter your postcode in the guide-price tool or contact form and we will confirm.
