Bathroom Renovation Staines-upon-Thames

A bathroom is a small room with a large amount of concealed work in it. Waste, water, ventilation, waterproofing and floor build up are all decided before the first tile is cut, and all of them are expensive to revisit. We run the whole sequence and coordinate the inspections. This page covers what a bathroom renovation in Staines-upon-Thames has to work with.

For Staines-upon-Thames, on London-derived ranges a full bathroom refit typically costs £6,000 to £20,000 or more; Surrey work generally runs below that. GS Renovation Ltd, a building contractor based in Potters Bar, does the work in Staines-upon-Thames: we carry the tanking, plumbing and tiling as one contract, with the electrics certified by a registered electrician.

How the job runs

1. Free design visit at your Staines-upon-Thames home and an itemised quote.
2. Strip-out, then first-fix plumbing and electrics.
3. Tanking to the wet areas, then tiling.
4. Sanitaryware and second fix, with notifiable electrics certified by a registered electrician.

The waste position sets the layout before the tiling does

The soil stack inside and the public sewer outside set the layout, and both are fixed before a tile is chosen. The Strategic Flood Risk Assessment states that the majority of Spelthorne is served by a Thames Water combined surface and foul water sewer system. It adds that such a system is typically designed and constructed to accommodate rainfall events with a 1 in 30 year return period or less.

Inside the house the limiting factor is the soil stack. A WC needs fall to reach it, and that fall has to be found within the depth of the floor. Moving a WC across a room is a floor job before it is a bathroom job. We take levels at the survey and tell you what the floor build up allows, so the layout you approve is one that can actually be plumbed.

Bathrooms in purpose built flats carry requirements a house bathroom does not

Census 2021 recorded 1,574 of the 4,011 households in the Staines ward living in purpose built blocks of flats or tenements, the largest single accommodation type in that ward.

A bathroom over another household changes the specification. The floor needs acoustic separation as well as a waterproof layer, the stack position is fixed by the building rather than by you, and access to communal services is granted by the freeholder or the managing agent. Protection of the escape route and the working hours the building allows also shape the programme. We agree all of that before the strip out, because a bathroom stopped halfway is a bathroom out of use.

Owner occupied households are buying the concealed work as much as the suite

Census 2021 recorded 1,915 of the 2,912 households in the Staines South ward as owner occupied, either owned outright or owned with a mortgage or loan. An owner occupier lives with the result for years rather than for a tenancy.

That argues for spending on what is buried. Tanking behind the tiles, a properly bedded tray, an extract fan ducted to outside rather than into a void, and pipework you can isolate all cost more once and less afterwards. The suite can be changed in a decade. The waterproofing cannot, without taking the room apart again.

The GS Renovation Difference in Staines-upon-Thames

A bathroom goes wrong behind the tiles, so that is where we put the attention. Waterproofing, falls, fixings into a substrate that will hold them, and ventilation that actually reaches outside all get specified before anything decorative is chosen. The trades follow one order, strip out, first fix, boarding and tanking, tiling, second fix, and we hold that order rather than letting a fitter arrive early. Where a structural element such as a chimney breast is involved, we appoint a structural engineer and build to the calculations issued. One point of contact runs the job from survey to handover. GS Renovation Ltd is fully insured, rated 4.9 from 31 reviews on MyBuilder, and quotations are free and without obligation.
