How much does a new bathroom cost in Surrey?

It's the first question almost everyone asks, and the honest answer is that it depends on the room and what you want in it. To give you a starting point, here's what national cost guides say, and then what changes the figure for a real bathroom.

What the national guides say

• Checkatrade's cost guide (updated March 2026) puts most new bathrooms, including materials, at £5,500 to £8,000, with an average of around £7,000, and luxury or complex projects at £14,000 and up.
• MyBuilder's 2026 guide puts labour alone at around £2,000 to £4,000 for a typical bathroom.

These are UK averages. Labour rates in Surrey and around London tend to sit above the national average, and the finish you choose makes a bigger difference than anything else.

What pushes the price up

• Moving things around. Keeping the WC, bath and basin where they are is cheapest. Moving the toilet means moving the soil pipe, which adds work.
• Wet rooms. The whole floor has to be formed to fall to the drain and fully tanked before tiling. See my guide to wet rooms and walk-in showers.
• Tiling. Floor-to-ceiling tiling, natural stone and large-format tiles take longer to set out and fit than a few rows of standard tiles.
• Bespoke glass. Made-to-measure screens cost more than off-the-shelf ones but fit the opening exactly.
• Hidden problems. Rotten floorboards, old pipework or uneven walls only show up once the old room is stripped out.
• Hot water. A powerful shower may need changes to the boiler or cylinder to perform properly.

What keeps the cost down

• Keeping the existing layout.
• Tiling only the wet areas and painting the rest with a bathroom-grade paint.
• Choosing a good mid-range suite rather than designer pieces. Spend where you touch things every day: the shower valve, the taps and the WC.

How to compare quotes

1. Check each quote covers the same things: strip-out and waste removal, plumbing, tiling, any electrics, plastering, glass and making good.
2. Ask who will do the work. One tradesman doing the plumbing, tiling and glass means fewer handovers and one person responsible for the finish.
3. Ask how the shower area will be waterproofed. It's invisible once the tiles are on, and it's the bit that decides whether a bathroom lasts.
4. Look at photos of finished work, not stock images.
