Working in Bournemouth
We cover every part of Bournemouth, including BH1, BH2, BH3 and 8 more postcode districts, and nearby Poole (4.6 miles) and Ferndown (6.1 miles).
Across a large town like Bournemouth, homes range from older terraces to newer estates; the survey tells us which pipework and floor we are dealing with. If your Bournemouth house has a combi boiler, a loft shower can usually run on mains pressure without a pump. If your Bournemouth loft conversion has a bedroom but no bathroom, the survey starts with where the soil stack runs and how much headroom you have.
Water across much of Dorset is hard. If your supply in Bournemouth 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
- A check of your hot-water system and of the pressure and flow you actually get at loft level
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.
