Luxury bathroom and wet-room refurbishment in Hitchin. Trusted, professional, 30+ years' hands-on experience.
A bathroom renovation is drainage, ventilation, waterproofing and finish, in that order. What fails later is behind the tiling, which is why the sequence matters more than the specification. We run the whole job under one contract, from strip out to the last seal. This page sets out what a Hitchin bathroom involves and what needs checking before the layout is agreed.

The Article 4 direction over the Hitchin Conservation Area removes permitted development rights for the installation, alteration or replacement of a chimney, flue or soil and vent pipe. Moving a bathroom to another part of the house can mean a new pipe on an outside wall. Inside that area, that is a planning matter rather than a detail for the plumber to settle on the day.
We check the designation for your address before the layout is fixed. If a new external pipe run is needed and the property is inside the Hitchin Conservation Area, we tell you at survey and look at whether the existing stack can take the new run instead.
Hertfordshire Building Control describes its remit as checking foundations, damp proofing, structural issues, insulation, ventilation, heating, sanitation, the accessibility of a building, fire protection and means of escape in case of fire. A bathroom sits on damp proofing, ventilation and sanitation at the same time. Where a new bathroom goes into a loft or over a joisted floor, structure joins that list.
We establish at survey which parts of your scheme are notifiable, make the application where one is needed, and book the inspection before the tiling goes on. Opening a finished bathroom back up costs more than the original work did.
A bathroom is a small room, so every mistake in it sits close to the next one. The waste falls, the ventilation route and the waterproofing behind the tiles are settled before a tile is ordered, because none of them can be put right afterwards without stripping the room back. We hold the plumbing, the electrics, the tiling and the making good under one contract, with one point of contact, so nothing waits on a subcontractor you have never met. In Hitchin there is a consent question in front of all that, because the Article 4 direction over the conservation area covers soil and vent pipes.

FAQ
Yes, wherever the scope can be pinned down at survey. GS Renovation quotes bathroom renovation as a fixed project price for most Hitchin homes, covering labour, materials and the North Hertfordshire District Council element. Where a genuine unknown sits behind plaster at the SG4 property we say so before starting rather than hiding it in a vague figure. Any variation is agreed in writing. Ring 07472 424 226 and GS Renovation will explain what fixing an SG4 price depends on. As a rough guide, bathroom renovation in London ranges from roughly £6,000 to £20,000 or more (indicative London ranges, MyBuilder and Checkatrade, 2026). Your figure depends on the size, specification and condition of the property, which is why we survey before quoting.
Drainage with a workable fall, mechanical ventilation, and a door that does not compromise the way out. Hertfordshire Building Control puts sanitation, ventilation and fire escape within its remit, and a WC under the stairs touches all three at once. The stairs are the route out for everyone above, so a door swinging into them is the detail that gets queried. We settle the layout before the studwork goes up.
Mechanical extract meets the ventilation requirement where it is sized and ducted properly, so a windowless bathroom works. Hertfordshire Building Control gives ventilation and damp proofing as part of its remit, and the two are connected: extract that discharges into a loft moves the moisture rather than removing it. The duct runs to an outside terminal and is insulated where it crosses cold space. We set that route before the ceiling is closed.
Inside the Hitchin Conservation Area, yes. The Article 4 direction there removes permitted development rights for the improvement or other alteration of a dwellinghouse, and a new opening in an elevation is an alteration. Outside that area the question is a different one, and obscured glazing and the outlook from the opening become the practical points. The lintel over it is then a building control matter. We deal with both routes at survey.
That turns on where the party line runs and on what the stack already carries, and it is checked before the layout is agreed. Hertfordshire Building Control gives sanitation as part of its remit, so the connection is inspected. A stack on a terrace can take waste from both houses, and adding a bathroom changes what it handles. Benslow Lane and Trevor Road are recorded as terraced streets of the mid to late 19th century. We trace the run from the roof down.
Yes, with care about where the moisture ends up. Hertfordshire Building Control gives insulation and damp proofing as part of its remit, and in a bathroom the two pull against each other. Brick making in Hitchin, in red and white brick, continued until the early 20th century, and a solid wall of that date has no cavity to keep water out. Insulating internally moves the dew point, so the make up, the vapour control layer and the extract are designed together.
