How Much Does It Cost to Replace a Toilet?

Replacing a toilet is one of the quickest bathroom upgrades. The fitting is usually affordable; the toilet you choose and what's found underneath make the biggest difference.

Typical prices

For a like-for-like swap in the same position, most of the cost is a few hours of a plumber's time plus a new pan connector, isolating valve and fixings.

What's included in a fitting price

A typical quote covers isolating the supply, removing the old toilet, fitting a new pan connector and isolating valve, fixing the new pan and cistern level and secure, connecting and testing for leaks. Ask whether disposal of the old toilet is included – some plumbers charge for it.

What pushes the price up

Old toilets cemented to the floor, a soil pipe in an awkward position, a damaged floor under the pan, or changing from a floor outlet to a wall outlet all add time. Moving the toilet to a different position is a different job altogether, involving new soil pipework.

Saving money

Buying a mid-range toilet from a reputable brand, choosing one that suits your existing soil pipe position and grouping the job with other small repairs can all help. If your toilet is only running or flushing weakly, a repair may be enough – a new toilet isn't always necessary.

Common questions

How long does it take to replace a toilet?

A straightforward replacement usually takes two to three hours.

Is it cheaper to repair or replace a toilet?

Fixing a running or weak flush is usually cheaper. Replace the toilet if it's cracked, very old or flushes poorly by design.

Do I need a plumber to replace a toilet?

It's a common DIY job for confident people, but a plumber will make sure the soil connection is sound and the toilet is fixed securely, which prevents future leaks.
