Working in Carshalton

In Carshalton we cover SM1, SM5 and SM6; we also cover Sutton, 1.9 miles away, and Mitcham.

In Carshalton, many bathrooms are in flats or converted houses, so we check lease consents, access and the floor below before we price. For a busy Carshalton household sharing one main bathroom, a thermostatic shower over a full-size bath is usually the most practical layout. Whether your Carshalton bathroom is a narrow galley or a square main room, we show you whether a separate shower would fit before you decide.

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

A free home survey covering room sizes, the soil stack position, your boiler or cylinder type and water pressure
A layout that keeps a full-size bath, with options for a shower over it or a separate enclosure if the room allows
Moisture-resistant boarding and tanking around the bath and shower before any tiling
New pipework, wastes and isolation valves, plus a thermostatic shower valve so the temperature holds when someone runs a tap

Decisions to make first

Bath shape

A standard 1700 mm bath fits most rooms. A shower bath widens at one end to give more standing room under the shower; a double-ended bath puts the waste in the middle so two children can share without one sitting on the plug.

Shower over the bath or separate

A shower over the bath with a fixed or hinged screen is the most space-efficient. A separate enclosure needs roughly another square metre of floor but means the bath queue no longer holds up the shower queue.

Rules that apply in England

In England, any new circuit, or any change to the wiring in a room with a bath or shower, is notifiable under Part P. Part G limits the hot water at a new bath to 48 °C only in a new dwelling or one created by change of use; it does not apply to a replacement bath in an existing house, but a thermostatic valve is a sensible choice where children bathe.

Family bathrooms in Carshalton: questions

How much does a family bathroom cost in Carshalton?

Is the home survey in Carshalton really free?

Yes. We visit, measure the room, check the pipework, drainage and electrics, and talk through what you want. You then get a written, itemised quote with no obligation to go ahead.

Do you cover SM1 in Carshalton?

Yes. We cover all of Carshalton, including SM1, SM5 and SM6, and nearby Sutton, Mitcham and Morden. Survey visits are free and arranged at a time that suits you.

Is the water hard in Carshalton?

Is a shower over the bath a good idea?

Yes, a shower over the bath is the most space-efficient way to have both in one room. Use a shower bath or a straight bath at least 700 mm wide, a glass screen and tiling or wall panels to full height around the bath. A common leak point is the seal between bath and wall, so the bath must be fully supported before it is sealed.
