What does a loft bathroom cost in Brentwood?

Guide price in Brentwood: £6,900–£13,750 including VAT, depending on the room and what you choose. Prices in East of England run at about 6% above the national guide, mainly because of labour rates. The figure depends on the size of the room, whether anything moves, and the products you pick.

Working in Brentwood

We cover every part of Brentwood, including CM13, CM14 and CM15, and nearby Billericay (4.9 miles) and Hornchurch (5.9 miles).

Homes in and around Brentwood vary, so we look at the floor, the walls and the water system before we price anything. If your Brentwood home has a gravity-drained WC on another floor, a macerator in the loft may open up more layout options. If your Brentwood house has a combi boiler, a loft shower can usually run on mains pressure without a pump.

Water across much of Essex is very hard. If your supply in Brentwood 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

An extractor fan ducted through the roof or a gable wall, with the duct insulated through cold spaces
Fitted furniture made to the eaves, so the low space behind the slope becomes storage
A shower pump on a gravity system, an electric shower, or advice on moving to mains pressure, depending on your system
A survey of the headroom across the room, with the usable height marked at each fitting position

Decisions to make first

Gravity or pumped waste

Gravity is silent and maintenance-free. A pumped waste or macerator lets fittings sit away from the stack, provided the house has a WC on gravity drainage elsewhere.

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.

Loft bathrooms in Brentwood: questions

How much does a loft bathroom cost in Brentwood?

A loft bathroom in Brentwood usually costs £6,900–£13,750 including VAT. Where you land in that range depends on the size of the room, whether the layout changes and the products you choose.

Is the water hard in Brentwood?

Who handles building control for a loft bathroom in Brentwood?

Building control for Brentwood 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 loft bathroom take?

Allow 6–12 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 Brentwood.

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.
