Working in Gravesend
As well as Gravesend itself (DA11 and DA12), we survey in Swanscombe, Grays and Longfield.
In Gravesend, as anywhere, the age of the house decides a lot: pipe sizes, floor construction and where the soil stack runs. If you are planning a wet room in Gravesend for level access, we design the fall and drain so the floor is flush from the doorway. For a wet room in a Gravesend flat, the first step is the lease, because freeholder consent is often needed before any work starts.
Supplies across most of Kent are very hard. If your supply in Gravesend 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
- A survey of the floor construction, the joist size and direction or the concrete slab, and the route to the soil stack
- A pre-formed floor former with a linear or centre drain, or a screed laid to fall
- Floor strengthening or a ply overlay on timber floors so the surface does not flex
Decisions to make first
Screen size
A screen of 1200 mm or more keeps spray off the rest of the room in most layouts. In a very small wet room, expect the whole floor to get wet.
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.
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.
