Working in Caernarfon
As well as Caernarfon itself (LL55), we survey in Bangor, Holyhead and Llandudno.
Caernarfon gets the same process as anywhere else: a free survey at your home and a written, itemised quote. For Caernarfon houses with only one bath, we talk through whether to keep it before you decide. If the bath in your Caernarfon home is mainly used for storing things, a walk-in shower in the same space is a quick, contained job.
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 low-profile tray, or a former and tanking for a level-access floor
- A glass enclosure, walk-in panel or frameless screen
- Silicone, a full-flow test and a tidy finish where the new tiling meets the old
- A thermostatic shower valve, with the pipework moved for the new head position
Decisions to make first
Low tray or level floor
A low-profile tray has a small lip. A level-access floor removes the step altogether but needs a former, tanking and a linear drain.
Your only bath?
If this is the only bath in the house, think about whether you, or a future buyer, will want one before you commit.
Rules that apply in Wales
In Wales, the Welsh Part P covers more electrical work than in England, and a new electric shower circuit must be notified. Disabled Facilities Grants in Wales can be up to £36,000, approved by the council before work begins.
