Working in Marlow

We work right across Marlow — SL7 — and in neighbouring Maidenhead and High Wycombe.

Being a smaller town does not change how we work in Marlow: free survey, written quote, one team. If your Marlow 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. For a loft bathroom in a tank-fed Marlow home, we work out how the shower will get its pressure before choosing a single fitting.

Water across much of Buckinghamshire is hard. If your supply in Marlow 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

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
A check of your hot-water system and of the pressure and flow you actually get at loft level
A check of the floor joists where a bath or large shower tray will sit

Decisions to make first

Roof window

A roof window over the bath or shower brings daylight and fresh air, but plan the blind for privacy and expect condensation on cold glass.

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 Marlow: questions

What is the price of a loft bathroom in Marlow?

A loft bathroom in Marlow 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.

Is the home survey in Marlow 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.

Do you cover SL7 in Marlow?

Yes. We cover all of Marlow, including SL7, and nearby Maidenhead, High Wycombe and Slough. Survey visits are free and arranged at a time that suits you.

Is the water hard in Marlow?

Can you put a toilet in a loft?

Yes, if the waste can fall to the soil stack or a macerator can be used. Gravity drainage is the first choice; a macerator is only allowed where the home already has a WC on gravity drainage, which in most houses means the main bathroom.
