Which options suit homes in Knowle?

Loft conversion en-suite

Most loft conversions include a shower room for the new bedroom. Head height decides where the shower can go, often within the dormer, and the waste ideally connects to the existing soil stack where it passes through the roof space. Planning it with the loft design keeps the plumbing simple.

New en-suite in the main bedroom

A stud wall is built across part of the bedroom, usually along the wall nearest the soil stack, to create a shower room. Insulating the new wall helps keep noise down. A pocket door saves the space a swinging door needs, and a window or roof light inside the en-suite is a bonus, though not essential if extraction is right.

Expect to budget between £3,800 and £15,000 depending on size and specification in Knowle. A new 1.5 m × 2.2 m shower en-suite formed in a double bedroom near the soil stack: typically £7,000–£9,500.

Questions about en-suite bathrooms in Knowle

How much disruption will there be in the bedroom?

The bedroom will be a work area for most of the job, so it's best to sleep elsewhere if you can. We move and cover furniture, protect the carpet or floor, and seal the doorway to keep dust in. Floorboards may be lifted along the waste route, sometimes into a neighbouring room, and we tell you in advance.

How do I book a survey in Knowle?

Send the form on this page, use the guide-price tool or call 0800 088 6248 free. We'll ask a few questions about your en-suite and arrange a time to visit.

What should I decide before the en-suite is built?

Decide which side of the bedroom you'd give up, where the bed and wardrobes will go afterwards, and whether you want a sliding pocket door. Choose the shower type and the suite early, as wall-hung toilets and concealed cisterns need frames built into the stud walls. Clear the room as far as possible before the start date.

Will I need permission from the council in Knowle?

You won't usually need planning permission, but the work must meet Building Regulations. Building control in Knowle is provided by Solihull Council or a registered building control approver, and some work is self-certified by registered installers.
