Working in Southsea

As well as Southsea itself (PO1, PO4 and PO5), we survey in Portsmouth, Gosport and South Hayling.

Southsea gets the same process as anywhere else: a free survey at your home and a written, itemised quote. If your Southsea home has a gravity-drained WC on another floor, a macerator in the loft may open up more layout options. If your Southsea house has a combi boiler, a loft shower can usually run on mains pressure without a pump.

Most of Hampshire has hard water. If your supply in Southsea 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

Fitted furniture made to the eaves, so the low space behind the slope becomes storage
A check of your hot-water system and of the pressure and flow you actually get at loft level
A shower pump on a gravity system, an electric shower, or advice on moving to mains pressure, depending on your system
An extractor fan ducted through the roof or a gable wall, with the duct insulated through cold spaces

Decisions to make first

Eaves storage

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

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.

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.

More about loft bathrooms

Loft bathrooms in Southsea: questions

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

A loft bathroom in Southsea usually costs £7,300–£14,500 including VAT. Room size, layout changes and your choice of products move the figure within that range. The free survey gives you an itemised quote, fixed in writing once the details are agreed.

Who handles building control for a loft bathroom in Southsea?

Building control for Southsea 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 Southsea.

Is the home survey in Southsea 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.

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.
