GS Renovation refits bathrooms and builds wet rooms in Borehamwood, starting with the parts that fail first: tanking, floor falls, drainage and ventilation. Tiling, brassware and heating follow once those are right. Plumbing and notified electrics are handled by our own coordinated trades, under one point of contact from strip out to snagging.
For Borehamwood, on London-derived ranges a full bathroom refit typically costs £6,000 to £20,000 or more; Hertfordshire work generally runs below that. GS Renovation Ltd, a building contractor based in Potters Bar, does the work in Borehamwood: we carry the tanking, plumbing and tiling as one contract, with the electrics certified by a registered electrician.

Bathrooms in Borehamwood's purpose built flats
The 2021 Census recorded 4,484 households in purpose built blocks of flats across the four Borehamwood wards. A bathroom in a flat has somebody living underneath it, and that changes the risk. A failed seal in a house damages your own ceiling. The same failure in a flat damages a neighbour's, which turns a repair into a liability question as well.
So the hidden work is where the money should go. We tank the wet area fully before any tiling, set the floor falls to the drain rather than trusting the existing gradient, and check the waste run can serve the layout you want. Ventilation matters as much, because an internal bathroom with no openable window depends entirely on extraction to clear moisture.
Housing in Borehamwood
The Council Tax list puts Borehamwood at about 15,090 homes, 36% flats against 63% houses; 2% went up before 1919, 8% between the wars and 90% after 1945. 38% of homes here are terraced; a terrace bathroom in Borehamwood vents front, back or up, never into a party wall.
Owner occupied homes and a bathroom that lasts
The 2021 Census recorded 7,262 owner occupied households across the four Borehamwood wards, 2,927 owned outright and 4,335 owned with a mortgage or loan. If you own the house, a bathroom refit is a long term decision rather than a quick refresh ahead of a sale, so the sensible place to spend is on the parts nobody will ever see.
That means the substrate behind the tiles, the tanking membrane, a properly graded waste and adequate extraction. Underfloor heating helps a solid floor bathroom dry between uses. New circuits and circuit changes near the bath or shower are notifiable under Part P, so they are certified by a registered electrician or notified to building control. We carry out the plumbing, tiling, heating and electrical coordination as one job, so there is nobody left to blame if something leaks.

The GS Renovation Difference in Borehamwood
Bathrooms fail behind the tiles, not on them. We tank the wet area, grade the falls, size the waste and sort the extraction before a single tile is fixed, then finish the room properly. Plumbing, tiling, heating and notified electrics come from one coordinated team with one point of contact. Fully insured, free no obligation quotations.

FAQ
Frequently Asked Questions about Bathroom Renovation Borehamwood
Can you quote bathroom renovation for a WD6 property over the phone?
A phone quote for bathroom renovation at a WD6 property would be a figure that changes, so GS Renovation gives the range, £6,000 to £20,000 or more (London-derived), and prices after a visit. What the job costs depends on what only a survey shows, because a timber floor over the room below decides how the wet area is built. Talk the scope through on 07472 424 226; the Borehamwood survey is free.
Does moving the bathroom to a different room need approval?
The work it involves does. A new soil connection, notched or trimmed floor joists, a new waste run and the electrical work all fall under the Building Regulations. Hertfordshire Building Control is the body, because Hertsmere Borough Council does not run its own service. Its checks cover damp proofing and structural issues among other aspects of construction. Where joists have to be altered, the engineer we appoint specifies how, and we build to that.
Can a shower room go into a converted garage?
Yes, and the width of the garage decides the planning side of it. Hertsmere states there is a general presumption in favour of converting a garage whose internal width is too narrow to park a car, and treats under 3 metres internally as too narrow. The building work is the harder half: insulation and damp proofing at the old door threshold, and a waste run that can reach the existing drainage.
Can a level access wet room be formed in a solid ground floor?
It depends on the floor build up and the drain position rather than on the ground beneath. The bedrock under Borehamwood is London Clay, described by the British Geological Survey as clay, silt and sand, which governs foundations rather than internal falls. Where the slab is broken out to set a drain, the depth and any effect on nearby footings are checked. Hertfordshire Building Control states its checks cover foundations and damp proofing.
Can a bathroom go in the loft with a dormer?
The dormer is the constraint rather than the bathroom. Hertsmere expects dormers to be located within the rear roof slope, and normally resists dormers in the front roof unless they are an established part of the street scene. Its key principle on dormers is that one should take up no more than 60 per cent of the roof slope. Head height, the new floor structure and the waste run then decide feasibility.
Is the tanking behind the tiles inspected by anybody?
Not as a routine visit. Hertfordshire Building Control states that its checks cover damp proofing among other aspects of construction, but a refit that involves no notifiable work brings no inspection of the waterproofing itself. The specification and the workmanship carry it instead, which is where a bathroom is won or lost. We photograph the tanking and the floor falls before tiling, so a record exists of what sits behind the finished surface.
