Working in Dorchester
We cover every part of Dorchester, including DT1, and nearby Weymouth (7.2 miles) and Yeovil (17.8 miles).
Dorchester gets the same process as anywhere else: a free survey at your home and a written, itemised quote. For a wet room in a Dorchester flat, the first step is the lease, because freeholder consent is often needed before any work starts. We quote wet rooms in Dorchester only after looking at the floor construction, because that is where most of the cost difference lies.
Supplies across most of Dorset are hard. If your supply in Dorchester 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
- A survey of the floor construction, the joist size and direction or the concrete slab, and the route to the soil stack
- Floor strengthening or a ply overlay on timber floors so the surface does not flex
- A thermostatic shower valve, exposed or concealed, with heads to suit your water system
- Extractor fan and lighting by a qualified electrician, tested and certified, with underfloor heating if you choose it
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.
Floor tile
Matt or textured porcelain with good slip resistance. Mosaic gives extra grip on a centre-drain floor because of its many grout lines.
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.
