Which towns do we cover in Hampshire?

Most of Hampshire has hard water. If your supply in Southampton 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. If your Southampton loft shower is weak or the waste drains slowly, the fix is often in the pump or the pipe fall rather than the shower itself.

What the job includes

  • A shower pump on a gravity system, an electric shower, or advice on moving to mains pressure, depending on your system
  • 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
  • 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
  • An extractor fan ducted through the roof or a gable wall, with the duct insulated through cold spaces

Decisions to make first

Where the shower goes

Under the ridge or in a dormer, where the full height is. A walk-in shower with a single panel is usually easier to fit to a roof line than a framed enclosure.

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.

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

A bathroom inside an existing loft room does not usually need planning permission, but forming one is normally building-regulations work because of the new drainage, extract ventilation and electrics. A macerator or pumped WC is acceptable only where the home also has a WC on gravity drainage. Under the water fittings rules, a shower pump must never be connected directly to the mains supply.

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 Hampshire: questions

How much does a loft bathroom cost in Hampshire?

Which towns in Hampshire do you cover?

How long does a loft bathroom take?

Most jobs take 6–12 working days on site once the products have arrived. We confirm a start date and a day-by-day plan when you approve the quote.

Is the water hard in Hampshire?

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

Is a bath too heavy for a loft floor?

A standard acrylic bath is usually fine on a loft floor built for a conversion, but a filled bath with someone in it is heavy, and stone-resin or cast-iron baths are much heavier still. We check the joist size, span and direction at the survey, and a heavy bath may need a structural check and strengthening first.
