Working in Windsor

As well as Windsor itself (SL4), we survey in Slough, Egham and Staines.

Homes in and around Windsor vary, so we look at the floor, the walls and the water system before we price anything. We plan luxury bathrooms in Windsor with drawings and a full product schedule, and the price is fixed in writing once the design is agreed. If you live in a listed building in Windsor, we flag any change that may need listed building consent, such as a new soil pipe through a wall.

Most of Berkshire has hard water. We plan easy-clean glass, rimless toilets and finishes that do not show limescale. Hardness varies street by street, so check the figure for your postcode with your water supplier.

What the job includes

Underfloor heating, layered lighting and any steam unit wired by a qualified electrician, tested and certified
A detailed survey of the floor structure, hot-water capacity, water pressure and flow
A full product schedule naming every piece of sanitaryware, brassware, tile and light fitting
Concealed thermostatic or digital shower valves, set into the wall to the depth the manufacturer specifies

Decisions to make first

Lighting

Layer it: IP-rated ceiling lights for general use, a lit mirror at the basin and low-level LED in niches or plinths for night, each on its own switch or dimmer.

Freestanding bath material

Acrylic is light and warm to the touch. Stone resin holds heat and feels solid but is much heavier. Cast iron is the heaviest of all and nearly always needs a structural check.

Rules that apply in England

In England, the new circuits a luxury bathroom often needs, for underfloor heating, a steam unit or a digital shower, are notifiable under Part P. An unvented hot-water cylinder, often fitted to feed a large shower, must be installed by a G3-qualified installer, and any work on the boiler must be done by a Gas Safe registered engineer.

Luxury bathrooms in Windsor: questions

How much does a luxury bathroom cost in Windsor?

A luxury bathroom in Windsor usually costs £13,500–£28,000 including VAT. Room size, layout changes and your choice of products move the figure within that range. The free survey gives you an itemised quote, fixed in writing once the details are agreed.

Is the water hard in Windsor?

Who handles building control for a luxury bathroom in Windsor?

Building control for Windsor is handled by the local council or an approved inspector. If your job needs sign-off — for example a new circuit, new drainage or a new extractor where there was none — we tell you at the survey and handle the notification as part of the work.

How long does a luxury bathroom take?

Allow 10–15 working days on site for most jobs, plus the lead time for products after you approve the quote. We give you a day-by-day plan before work starts in Windsor.

Do I need an unvented cylinder for a rainfall shower?

Not always, but a large rainfall head needs strong flow and plenty of hot water. A combi boiler may struggle to feed one, and a tank-fed system would need a pump. An unvented cylinder gives mains pressure from a stored supply and suits larger showers; it must be installed by a G3-qualified installer. We test your pressure and flow at the survey.
