A bathroom installation replaces your old suite with new sanitaryware, a bath or shower, tiling and fittings, including the plumbing, electrics, ventilation and waterproofing needed for a complete, watertight room.
Addresses across PL25 fall within our coverage for a new bathroom, so if your home is in St Austell we can arrange a survey on a day that works for you. We inspect the existing building, discuss materials and layout, and then price the agreed specification in writing. Expect a guide range of £5,100–£12,000 including VAT before that visit.

Homes in Cornwall
Older Cornish homes are often built of granite or slatey local stone, with slate roofs and sometimes slate-hung walls facing the weather. Cob cottages survive in places, Truro and Falmouth keep Georgian and Victorian streets, and many towns have rendered post-war houses, bungalows and newer estates on their edges.
Stone and cob properties often need breathable lime render, careful repointing and roof repairs. Post-war and newer homes commonly benefit from new windows, roofline renewal, external rendering and single-storey extensions.
These patterns matter for a new bathroom: older walls, roofs and floors in St Austell can need different materials or extra preparation compared with newer homes.
Planning and building rules in St Austell
Planning law differs across the UK. For a home in St Austell, it is the England rules below that count, and we check them with the council ahead of any quote.
Internal work such as a new kitchen, bathroom, flooring, plastering or decorating does not need planning permission in England, unless the house is listed, when listed building consent may be needed even for internal changes.
Some internal work is covered by Building Regulations: new electrical circuits and work in bathrooms (Part P), new drainage, structural changes, extractor ventilation and any new window. Notifiable work is certified by a registered installer or by building control.
Rules change and every property is different, so we check the planning history and constraints for your address before we quote.
What happens after you get in touch?
We look at the job
We arrange a free site survey on a date convenient to you. We measure up, look at the existing structure and access, and discuss your plans for a new bathroom so the price reflects your home.
Price and scope agreed
After the survey we send a quote for a new bathroom that fixes the price for the scope we've agreed. If you want to change materials or scope, we revise it in writing before anything is booked.
Getting ready
Next comes planning the work itself. We set a start date that suits you, line up the right trades, and make sure any approvals for a new bathroom are in place before the first day on site.
On site to finish
On site, the agreed plan is followed and any change is put in writing first. At completion we do a final clean, go through the snagging list with you and leave you with the relevant documents.
How we work
Questions about a new bathroom in St Austell
Can I move the toilet to a different position?
Moving a toilet is usually possible, but it is limited by the soil pipe, which needs a large-diameter pipe with a steady fall to the soil stack. Short moves along the same wall are often simple, while moving it across the room may mean lifting floors or boxing in pipework. A macerator pump is an option where gravity will not work. We check the stack position during the survey.
Do you cover Truro, Newquay and Falmouth?
Yes. As well as St Austell, we cover Truro, Newquay and Falmouth and the rest of Cornwall. Our coverage is UK-wide, so the process is the same wherever you are: a free site survey, a quote in writing that fixes the price for the agreed scope, and one point of contact while the work is planned and carried out.
What ventilation does a bathroom need?
A bathroom needs mechanical ventilation, usually an extractor fan, to remove steam and help prevent condensation and mould. Building regulations set minimum extraction rates for new or refitted bathrooms. A fan linked to the light with an overrun timer, or one with a humidity sensor, works well. Ducting should vent outside by the shortest practical route. We include a suitable fan in every bathroom quote.
What happens at the survey?
We visit your home at a time that suits you, look at the area involved, take measurements and check access, condition and any services that might be affected. We talk through what you want from a new bathroom, explain the options and answer questions. There is no charge and no obligation; afterwards we send a written quote.
Is a wet room right for my home?
A wet room is a fully waterproofed room with a shower area that drains through the floor, with no tray or step. It suits accessible bathrooms and modern designs, and makes cleaning easy. It needs a floor with enough depth for a gentle fall to the drain, and careful tanking of the whole room. Timber floors often need strengthening. We check suitability at the survey.
