A bathroom renovation isn't like buying a sofa from a furniture deal. You can't just order it, have it delivered next week, and be done. It's messier, longer, and more expensive than most people expect.
Let's start with actual numbers. A basic bathroom refresh, where you're replacing fixtures and redecorating, typically costs between £3,000 and £7,000. A mid-range renovation, where you're adding new flooring, upgrading plumbing, and installing fitted furniture, runs £7,000 to £15,000. A full-scale bathroom overhaul with structural changes, luxury finishes, and bespoke bathroom furniture? You're looking at £15,000 to £30,000 or more.
These figures assume you're working with a competent tradesperson and not discovering asbestos or subsidence halfway through. Spoiler alert: surprises happen.
Labour is the biggest chunk. A skilled plumber costs £40 to £60 per hour. An electrician charges similar rates. Tilers, plasterers, and bathroom fitters work on daily or project rates, typically £150 to £250 per day. If your renovation takes four weeks with multiple trades on site, labour alone could be £6,000 to £8,000.
Materials come next. Bathroom suites, including toilet, basin, and bath, range from £400 for basic white porcelain to £2,500 for contemporary designer pieces. Tiles run £15 to £80 per square metre depending on quality. A single bathroom, roughly eight square metres, means £120 to £640 just for floor tiles. Wall tiles cost similar amounts. Waterproofing products, grout, adhesive, and sealants add another £500 to £1,000.
Fitted bathroom furniture and storage cabinets are where many people spend more than planned. A decent vanity unit with storage costs £400 to £1,200. Medicine cabinets with mirrors, £200 to £600. These items matter because they define how the space feels and functions. Unlike quick furniture deals online, bathroom furniture needs careful measurement and professional installation.
Heating and ventilation systems, essential for preventing damp, run £300 to £800. Lighting costs £200 to £600. Plumbing adjustments, if you're moving pipes or adding outlets, add £800 to £2,000.
A straightforward update with new paint, new fixtures, and no structural changes takes two to three weeks. You're coordinating between a plumber for two days, a plasterer for three days, tilers for four or five days, and an electrician for one day. It's achievable if everyone shows up when promised.
A standard renovation with partial retiling, new flooring, and replumbing takes four to six weeks. There's waiting time between trades. Plaster needs to dry. Waterproofing needs setting time. Grout needs curing. These gaps aren't your tradesperson being slow. They're physics.
A complete strip-out and rebuild, where you're removing everything and starting fresh, takes eight to twelve weeks. You need time to identify what needs replacing in the walls. If there's damp damage, poor ventilation history, or outdated plumbing behind the walls, contingency time extends things further.
All timelines assume no unexpected issues. The average bathroom renovation hits at least one problem: rotted joists behind tiles, pipes in awkward places, or electrics needing rerouting. Budget an extra week and an extra 10 per cent for costs.
First, sort your design before work starts. This sounds obvious but most people don't. You need to choose your bathroom suite, tiles, flooring, paint colour, lighting style, and storage furniture before the first tradesperson arrives. Changes mid-renovation cost time and money. If you're buying bathroom furniture, get it ordered early. Delivery times for fitted pieces run six to ten weeks. You don't want renovations finished and no vanity unit to install.
Second, arrange proper quotes from at least three different bathroom fitters or plumbers. Ask them to walk through the space with you and identify potential issues. Get everything in writing. A proper quote should itemise labour, materials, and timelines. If someone gives you a single figure with no breakdown, find someone else.
Third, sort budget contingency. Not reserves for nice extras, but genuine contingency for problems. A 15 per cent buffer is standard. On a £10,000 project, that's £1,500 you're not spending unless needed.
Fourth, plan where you're actually going to shower and use a toilet during the renovation. Most bathroom work takes the bathroom out of action completely. You need access to another bathroom or temporary arrangements elsewhere.
Fifth, check Building Regulations compliance. Any work involving structural changes, new electrics, or changes to ventilation may need approval. Local authority inspections cost £200 to £400 but they're worthwhile. Skipping them creates problems when you sell.
This is where your renovation gets personal. Cheap bathroom furniture looks cheap quickly. Thin cabinet doors, poor hinges, and budget taps fail within two to three years. Mid-range fitted furniture lasts ten to fifteen years with normal use. Quality pieces last twenty years or more.
Measure carefully. A badly fitted vanity unit dominates your daily experience. If the tap doesn't clear the basin edge properly or drawers rub against each other, you'll notice every morning. Unlike buying furniture online where you can return it, fitted bathroom furniture lives with your decision.
Consider your lifestyle. If you have young children, choose flooring that's slip-resistant when wet. If you're in a hard water area, avoid chrome finishes that spot easily. These details matter more in bathrooms than in any other room.
A bathroom renovation isn't quick or cheap, but it's usually necessary. Most UK bathrooms need attention every fifteen to twenty years. When you're planning yours, start with realistic costs, book your trades early, and buy your furniture with intention rather than panic. The result is a space that works properly and lasts.
