Working in Penzance
We cover every part of Penzance, including TR18, and nearby Camborne (12.5 miles) and Redruth (15.9 miles).
Being a smaller town does not change how we work in Penzance: free survey, written quote, one team. For a loft bathroom in a tank-fed Penzance home, we work out how the shower will get its pressure before choosing a single fitting. We plan loft bathrooms in Penzance around the roof line, so the shower sits where you can stand and the eaves become storage.
Supplies across most of Cornwall are soft. If that holds for your street in Penzance, limescale on shower glass and heads builds up slowly and a squeegee after use is usually enough. 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
- A shower pump on a gravity system, an electric shower, or advice on moving to mains pressure, depending on your system
- Fitted furniture made to the eaves, so the low space behind the slope becomes storage
- A drainage route from the loft to the soil stack with enough fall, or a pumped waste or macerator where the rules allow it
Decisions to make first
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
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.
