Working in Grantham

In Grantham we cover NG31; we also cover Sleaford, 11.4 miles away, and Newark on Trent.

Homes in and around Grantham vary, so we look at the floor, the walls and the water system before we price anything. If your Grantham bathroom is upstairs on timber joists, we check their size and direction before planning the wet room floor. If you are planning a wet room in Grantham for level access, we design the fall and drain so the floor is flush from the doorway.

Supplies across most of Lincolnshire are hard. If your supply in Grantham 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

Full tanking of the floor and the shower walls, with sealed corners, pipe collars and a sealed drain connection
Slip-resistant porcelain floor tiles and wall tiling
A frameless glass screen fixed to the wall and floor
A pre-formed floor former with a linear or centre drain, or a screed laid to fall

Decisions to make first

Former or screed

A pre-formed board gives a consistent fall and suits timber floors. A sand and cement screed suits concrete slabs and larger shower areas.

Open or screened

A fully open shower with no glass only works in a larger room, with the basin, WC and towels well away from the spray.

Rules that apply in England

In England, a new drain connection or changes at the soil stack can be building-regulations work under Part H, and new circuits or changes to the wiring in the room are notifiable under Part P. If the wet room is a newly formed bathroom, Approved Document F requires extract of 15 litres per second intermittent or 8 litres per second continuous.

More about wet rooms

Wet rooms in Grantham: questions

How much should I budget for a wet room in Grantham?

Who handles building control for a wet room in Grantham?

Building control for Grantham is handled by the local council or an approved inspector. If your job needs sign-off — for example a new circuit, new drainage or a new extractor where there was none — we tell you at the survey and handle the notification as part of the work.

How long does a wet room take?

Allow 5–10 working days on site for most jobs, plus the lead time for products after you approve the quote. We give you a day-by-day plan before work starts in Grantham.

Is the home survey in Grantham 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 wet rooms leak?

A properly tanked wet room should not leak. When one does, the cause is usually a gap in the membrane at a corner or pipe, a poor drain connection, or a floor that flexes and splits the seal. Leaks in wet rooms are expensive to trace, which is why the floor is stiffened first and the tanking is checked before tiling.
