Working in Winchester

In Winchester we cover SO21, SO22 and SO23; we also cover Eastleigh, 6.9 miles away, and Romsey.

In a city the size of Winchester, parking and access for a skip are worth sorting before the start date — we will ask at the survey. If your Winchester 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 Winchester around the roof line, so the shower sits where you can stand and the eaves become storage.

Supplies across most of Hampshire are hard. If your supply in Winchester 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
An extractor fan ducted through the roof or a gable wall, with the duct insulated through cold spaces
Electrics by a qualified electrician, tested and certified, then tiling, testing and handover
Fitted furniture made to the eaves, so the low space behind the slope becomes storage

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.

Eaves storage

Low cupboards built into the slope behind the WC or basin take clutter out of the room and hide the pipework.

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 Winchester: questions

How much should I budget for a loft bathroom in Winchester?

A loft bathroom in Winchester usually costs £7,300–£14,500 including VAT. Expect the lower end for a like-for-like job with standard products, and the upper end if things move or you choose premium finishes. Your quote is itemised and fixed in writing once agreed.

Is the water hard in Winchester?

Who handles building control for a loft bathroom in Winchester?

Building control for Winchester 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 Winchester.

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.
