Working in Isleworth
We cover every part of Isleworth, including TW3, TW5 and TW7, and nearby Hounslow (0.9 miles) and Heston (1.5 miles).
In Isleworth, many bathrooms are in flats or converted houses, so we check lease consents, access and the floor below before we price. If you want to lose the bath and gain storage in your Isleworth bathroom, we show you both options before you decide. If your Isleworth bathroom has pipes boxed in at odd angles, a fitted run is often the neatest way to hide them for good.
Water across much of Greater London is very hard. 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
- Layout options drawn to your room, including where the furniture run, bath or shower and towel rail will go
- Fitting of the furniture, worktop, sanitaryware and glass, then silicone, testing and a clean handover
- First and second-fix plumbing, including concealed cistern frames and new isolation valves
- Supply of the suite, fitted furniture, worktop, brassware, tiles and accessories
Decisions to make first
Bath, shower or both
Keep a bath for children or soaking, swap it for a walk-in shower if no one uses it, or plan both if the room is big enough.
Furniture finish
Matt or gloss lacquer, wood-effect, painted shaker or handleless. Darker finishes hide marks; lighter ones make a small room feel bigger.
Rules that apply in England
In England, new circuits and most electrical changes in a bathroom are notifiable under Part P, so they must be done by an electrician registered with a competent person scheme or notified to building control. If you are adding a new extractor fan, Approved Document F gives 15 litres per second as the usual intermittent extract rate.
