- Free design visit, itemised quote
A bathroom renovation is mostly plumbing, waterproofing and ventilation, with tiling as the visible part. Getting the falls, the tanking and the extract right is what decides whether it is still sound in ten years. We run the trades on one programme, and where a wall or a floor is structural we appoint the engineer and build to what is issued. This page sets out the Dunstable specifics.
For Dunstable, on London-derived ranges a full bathroom refit typically costs £6,000 to £20,000 or more; Bedfordshire work generally runs below that. GS Renovation Ltd, a building contractor based in Potters Bar, does the work in Dunstable: we carry the tanking, plumbing and tiling as one contract, with the electrics certified by a registered electrician.

A building notice lets bathroom work start 48 hours after it is deposited
That is the route under a building notice to Central Bedfordshire Council. For a bathroom replaced in the same position, with the electrics and the ventilation brought up to current standards, it is the straightforward option. It removes the wait for plans approval, and the inspections still happen.
One exclusion is worth knowing. The council says a building notice cannot be used where you are building over or close to a public sewer. A new soil connection, a relocated stack or an external drainage alteration can put you in that position, and then the full plans route applies. We check the drainage layout before the route is chosen.
Housing in Dunstable
Count the homes in Dunstable and you get about 17,660: 79% built since 1945, 12% between the wars and 9% before 1919, with flats at 28% and houses at 72%. A semi in Dunstable can vent its bathroom through the flank, and 33% of homes here are semi-detached.
Purpose built flats house 22 per cent of Dunstable households, against 17 per cent nationally
Those are the 2021 Census figures for the five areas covering the town. A bathroom in a flat carries constraints a house does not. The waste has to reach a shared stack at a workable fall. The floor build up is limited by the door and by what sits beneath. The lease sets what can be altered and when the work can be done.
Sound and water both travel downwards in that situation. An acoustic mat under the floor finish, a properly formed tanked tray rather than a sealed one, and an extract that genuinely reaches outside air are the three things worth paying for. We set them out in the quotation rather than leaving them as extras.
- Underfloor heating and heated towel rails
- En-suite creation in bedrooms and loft rooms
- Freestanding and built-in bath installation

Why Choose GS Renovation in Dunstable
A bathroom fails at the details you cannot see once it is tiled: the fall to the gully, the tanking behind the tray, the fixings in a stud wall carrying a wall hung pan. We fit those to the manufacturer's detail and photograph them before they are covered, so there is a record. One programme covers the strip out, the first fix, the tanking, the tiling and the second fix, with one point of contact throughout. GS Renovation Ltd is fully insured, registered in England, company number 14611254, and quotations are free and without obligation.

FAQ
Frequently Asked Questions about Bathroom Renovation Dunstable
Is a cheap bathroom renovation quote in Dunstable worth taking?
Be careful with a cheap bathroom renovation quote in Dunstable, particularly if nobody has visited. Pricing a post-war suburban home unseen is how a low figure becomes a high one halfway through, because soil stack distance decides where a Dunstable WC can go. GS Renovation surveys, itemises within £6,000 to £20,000 or more (London-derived) and holds the total. A second opinion on the LU6 quotation costs nothing.
Why does mould keep coming back on the bathroom wall of a postwar semi?
Ventilation and wall temperature, in that order. Valuation Office Agency records put about 42 per cent of Dunstable dwellings in the 1945 to 1972 build periods, against about 26 per cent nationally, and at the 2021 Census 40 per cent of households lived in a semi detached house. Bathrooms in that stock sit against a cold external wall with an extract that runs too briefly. An extract reaching outside air, a timed run and insulation behind the tiling address the cause.
Can the floor of a postwar Dunstable house take a wet room or a freestanding bath?
It is a joist question, answered before the tiles are chosen. Council tax records count about 1,380 homes built between 1955 and 1964 in the Dunstable East area, and about 61 per cent of Dunstable South homes date from 1945 to 1972. Timber floors of that period were sized for a bath standing on legs, not for a filled bath over a tiled screed. Where joists need doubling or trimming, the engineer specifies it.
Can a bathroom on a solid wall in central Dunstable be tanked and tiled as normal?
Not on the build up used for a cavity wall. Council tax records count about 560 homes built before 1900 and about 620 built between 1900 and 1918 in the Dunstable Central area, the highest pre 1919 counts of the town's five areas. A solid wall was built to let moisture back out, so a sealed layer against bare masonry traps it. An insulated, breathable build up behind the tiling is the detail that lasts.
Can a bathroom go in the loft of a Dunstable house?
The structure decides it. Water, a bath or a tray and a tiled floor add load a roof space was not designed to carry, so the floor is designed rather than boarded over. The full plans application to Central Bedfordshire carries those calculations. Valuation Office Agency records put about 42 per cent of Dunstable homes in the 1945 to 1972 build periods, where the roof timbers were sized for the roof alone.
