Working in Guildford

We cover every part of Guildford, including GU1, GU2 and GU4, and nearby Godalming (3.8 miles) and Woking (5.8 miles).

Homes in and around Guildford vary, so we look at the floor, the walls and the water system before we price anything. If your Guildford home has a gravity-drained WC on another floor, a macerator in the loft may open up more layout options. We plan loft bathrooms in Guildford around the roof line, so the shower sits where you can stand and the eaves become storage.

Supplies across most of Surrey are hard. If your supply in Guildford is the same, limescale on shower glass and heads is a real issue: easy-clean glass, rub-clean nozzles and a squeegee make a big difference. Hardness varies street by street, so check the figure for your postcode with your water supplier.

What the job includes

A check of the floor joists where a bath or large shower tray will sit
A check of your hot-water system and of the pressure and flow you actually get at loft level
A drainage route from the loft to the soil stack with enough fall, or a pumped waste or macerator where the rules allow it
A survey of the headroom across the room, with the usable height marked at each fitting position

Decisions to make first

Getting the water pressure

A pumped shower suits a gravity system with a cold tank; an electric shower heats cold mains water at the point of use; a combi or unvented cylinder gives mains pressure throughout.

Bath or no bath

A bath under the slope makes good use of low space, but the floor has to carry it when it is full of water and someone is in it.

Rules that apply in England

In England, new drainage and a new connection to the soil stack fall under Part H, a new bathroom needs extract of 15 litres per second intermittent or 8 litres per second continuous under Approved Document F, and new circuits are notifiable under Part P. If the work includes an unvented hot-water cylinder, it must be fitted by a G3-qualified installer.

Is the home survey in Guildford 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 GU1 in Guildford?

Yes. We cover all of Guildford, including GU1, GU2 and GU4, and nearby Godalming, Woking and Aldershot. Survey visits are free and arranged at a time that suits you.

How much headroom do you need for a loft shower?

Plan for around 2 m of clear height over the whole shower area, and enough standing height in front of the basin and WC. A bath can sit lower under the slope as long as you can stand up where you get in and out. We mark the usable height at each position on the survey drawing.
