Guide to Bathroom Renovation Costs
UK bathrooms are notoriously small. The standard footprint of an upstairs family bathroom in a typical semi-detached house is roughly 2m by 2m (4 square metres). Despite their size, refitting a bathroom is technically complex because it requires three separate trades: a plumber, an electrician, and a plasterer/tiler working in a very confined space.
The Shocking Reality of "Cheap" Suites
You can often see complete bathroom suites (Toilet, Basin, Bath) advertised in DIY stores for £300. This leads homeowners to vastly underestimate the cost of a refit.
In reality, the 'Suite' makes up less than 20% of your total bill. The true costs lie in:
• Labour: Removing the old heavy iron bath, dragging it downstairs, and spending 6 days putting the new room together.
• Sub-materials: Copper pipes, plastic waste pipes, sealants, plasterboard, cement board, tile adhesive, and grout (which can easily cost £400+ alone).
• Waste Disposal: Hiring an 8-yard skip for the old plaster and tiles (£250-£350).
Tips to Reduce the Cost
1. Don't move the plumbing
Keep the toilet, shower, and sink precisely where they are. Swapping like-for-like means the fitter can utilise the existing water feeds and waste pipes without ripping up the floorboards. Moving a toilet even one metre across a room could add two days of labour to your bill.
2. Strip it out yourself
Bathroom fitters charge £250 a day. Ripping off old tiles, unscrewing old cabinets, and carrying the rubbish outside into a skip takes about one to two days. If you are physically able to do this demolition work yourself over a weekend before the plumber arrives, you instantly save hundreds of pounds in labour.
3. Use shower panels instead of tiles
Tiles are cheap to buy but incredibly expensive and time-consuming to install. Using modern PVC shower wall panels instead of tiles inside a shower enclosure drastically reduces fitting time, completely eliminates grout mould, and is highly cost-effective.
