- Rated 4.9 from 31 reviews on MyBuilder
- Guide from £6,000 (London-derived)
- Free design visit, itemised quote
A bathroom renovation is short but dense: drainage, ventilation, electrics, tanking and tiling all inside one small room. The order of work decides the finish. In Stevenage the drainage route and, for council tenants, the landlord's written permission are the two things to settle before the strip out begins.
For Stevenage, 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 Stevenage: we carry the tanking, plumbing and tiling as one contract, with the electrics certified by a registered electrician.

Where a Stevenage bathroom drains to
Thames Water is the sewerage undertaker for Stevenage, and all wastewater and sewage from the town is treated at Rye Meads on the Hertfordshire and Essex border.
Moving a bath, shower or WC changes the falls on the waste and the connection into the stack. Where a new connection to the public sewer is involved, that is a matter for the undertaker rather than the council. We establish the drainage route at survey, before anything is taken out.
Housing in Stevenage
Stevenage has about 38,430 homes on the Council Tax list: 2% pre-1919, 1% interwar and 96% post-war, with flats making up 24% and houses 76%. 52% of homes here are terraced; a terrace bathroom in Stevenage vents front, back or up, never into a party wall.
Written permission comes before the strip out in a council home
Tenants of Stevenage Borough Council must have the council's written permission before they carry out alterations or improvements to their home.
A bathroom replacement counts as an improvement, so the request goes in before a start date is agreed. We survey and quote while it is being considered, and hold the programme until the permission is confirmed in writing.
- Floor strengthening before large-format tiles or stone

FAQ
Frequently Asked Questions about Bathroom Renovation Stevenage
What does the bathroom renovation quotation for a Stevenage home cover?
The bathroom renovation quotation for a Stevenage home covers the whole job through to sign-off, typically within £6,000 to £20,000 or more (London-derived). It lists the structural work, the following trades, Part F extraction to outside, and Part P certification for any new circuit, and the making good at SG1, with any Part P electrical certificate shown as its own line. GS Renovation issues it in writing so you have something to hold us to.
Does new drainage close to a public sewer change the approval route?
It can close off the quicker route. Hertfordshire Building Control states that a Building Notice cannot be used where you are building over or within 3 metres of a public sewer. The alternative is a full plans application, which is checked before work starts rather than allowing a start 48 hours after a notice. Establish where the sewer runs before the drainage layout is drawn, because the route decides the programme as much as the pipework does.
Does the council's Warm Homes programme cover a bathroom replacement?
No. That programme is the council's own work in its own housing stock, with 209 homes upgraded in Wave 1, 237 in Wave 2 and a further 379 in Wave 3. A privately funded bathroom sits outside it, and nothing in the programme sets the specification, the fittings or the timing for one. If the council is your landlord, the alteration route runs through the council's written permission rather than through the fund.
Will an upstairs floor carry a freestanding bath?
The joists are checked before the bath is chosen. The local plan states that most of the town's buildings were built between the 1950s and the 1970s and are coming to the end of their useful life, and floor structures of that period were sized for the fittings of the time. A filled freestanding bath with an occupant is a heavy load concentrated in one part of the room. Where strengthening is needed, an engineer is appointed and we build to the calculations issued.
Who certifies the electrical work in a new bathroom in Stevenage?
Either a registered electrician self certifying the work, or the building control body, which here is Hertfordshire Building Control Limited rather than the council. A bathroom counts as a special location, so circuits, bonding and the position of accessories all have to suit the zones around the bath and shower. The certificate belongs with the house records for a future sale. Inspection visits are booked by phone or WhatsApp, and we make those bookings.
