Working in Carmarthen

As well as Carmarthen itself (SA31), we survey in Llanelli, Ammanford and Gorseinon.

Being a smaller town does not change how we work in Carmarthen: free survey, written quote, one team. We plan loft bathrooms in Carmarthen around the roof line, so the shower sits where you can stand and the eaves become storage. For a loft bathroom in a tank-fed Carmarthen home, we work out how the shower will get its pressure before choosing a single fitting.

Most of Dyfed is supplied with soft water. If that holds for your street in Carmarthen, 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

Electrics by a qualified electrician, tested and certified, then tiling, testing and handover
A drainage route from the loft to the soil stack with enough fall, or a pumped waste or macerator where the rules allow it
A check of your hot-water system and of the pressure and flow you actually get at loft level
A shower pump on a gravity system, an electric shower, or advice on moving to mains pressure, depending on your system

Decisions to make first

Roof window

A roof window over the bath or shower brings daylight and fresh air, but plan the blind for privacy and expect condensation on cold glass.

Bath or no bath

A bath under the slope makes good use of low space, but the floor has to carry it when it is full of water and someone is in it.

Rules that apply in Wales

Wales applies its own Part P, with a wider notifiable list than England, and its own Part F with similar extract rates. Part H covers the new drainage route down from the loft.

Loft bathrooms in Carmarthen: questions

How much does a loft bathroom cost in Carmarthen?

A loft bathroom in Carmarthen usually costs £6,000–£12,000 including VAT. Where you land in that range depends on the size of the room, whether the layout changes and the products you choose. After the free survey you get an itemised written quote, and the price is fixed in writing once the layout and products are agreed.

Is the home survey in Carmarthen 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 you cover SA31 in Carmarthen?

Yes. We cover all of Carmarthen, including SA31, and nearby Llanelli, Ammanford and Gorseinon. Survey visits are free and arranged at a time that suits you.

Is the water hard in Carmarthen?

Is a bath too heavy for a loft floor?

A standard acrylic bath is usually fine on a loft floor built for a conversion, but a filled bath with someone in it is heavy, and stone-resin or cast-iron baths are much heavier still. We check the joist size, span and direction at the survey, and a heavy bath may need a structural check and strengthening first.
