Working in Caernarfon

In Caernarfon we cover LL55; we also cover Bangor, 8.3 miles away, and Holyhead.

Caernarfon gets the same process as anywhere else: a free survey at your home and a written, itemised quote. In a compact Caernarfon bathroom, a wet room frees the space a tray and enclosure would take, but expect the whole floor to get wet. We quote wet rooms in Caernarfon only after looking at the floor construction, because that is where most of the cost difference lies.

Most of Gwynedd is supplied with soft water. If that holds for your street in Caernarfon, limescale on shower glass and heads builds up slowly and a squeegee after use is usually enough. 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
Slip-resistant porcelain floor tiles and wall tiling
Strip-out, waste removal, a final flow test to the drain and handover
A frameless glass screen fixed to the wall and floor

Decisions to make first

Linear or centre drain

A linear drain along one wall lets the floor fall in a single direction, so large tiles can be laid without awkward cuts. A centre drain needs a four-way fall and suits smaller tiles or mosaic.

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 Wales

In Wales, Part H covers new drainage and the Welsh Part F sets similar extract rates. The Welsh Part P makes more electrical work notifiable than in England, so the electrician should notify and certify the work.

Wet rooms in Caernarfon: questions

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

A wet room in Caernarfon usually costs £5,600–£11,250 including VAT. Where you land in that range depends on the size of the room, whether the layout changes and the products you choose.

Is the water hard in Caernarfon?

Who handles building control for a wet room in Caernarfon?

Building control for Caernarfon 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 Caernarfon.

Can I have a wet room in a flat?

Often, but check your lease first. Freeholder consent is commonly needed, especially where the drainage or the floor changes, and the risk of a leak into the flat below means the tanking and drain connection must be done with care. Sound insulation in the floor matters too.
