Installing a new bath is a job that can be carried out on a DIY basis, by a plumber, or sometimes by a specialist bathroom fitter recommended by your supplier.

The water will need to be turned off while the work is carried out, so bear this in mind before work begins.

If the new bath is being fitted into the same position as the old one, then you can get to work straight away, but if it is to be located in a new position then the water supply and waste pipes will need to be extended to reach this new position.

If the bath you have chosen is a style which fits within a supporting frame or ‘cradle’, then this will be fitted first. If you are going for a built-in style of bath, you might decide to build a timber frame for it to sit in, which can then be covered with tiles, panelling and the like. (Read about freestanding and whirlpool baths below.)

Next, the taps will be fitted to the bath, along with the flexible tap connectors. The plug hole outlet will also be fitted and the trap connected to the bottom of the waste outlet.

The bath can then be fitted into its required position. The plumber or fitter will ensure the bath is level and use the adjustable feet (fitted to most baths) to get it into a position they are happy with.

The flexible tap connectors will then be matched up to the supply pipes, before the water is switched on and the whole thing is tested for leaks.

Finally, the panelling can be fitted into place. If you are tiling around the bath, it is recommended that you wait until the bath has been used at least once to allow it to settle into its final position, to avoid seals being broken or tiles cracking.

Step-by-Step

  1. Switch the water off at the mains.
  2. Extend or install the water supply and waste pipes if the bath is being fitted in a new position.
  3. Fit or build in the bath frame.
  4. Fit the taps to the bath, with holes drilled if necessary.
  5. Fit flexible hose connectors to the taps.
  6. Fit the plug hole outlet and connect the trap to the bottom of the waste outlet.
  7. Fit the bath into position.
  8. Fit the tap connectors to supply pipes.
  9. Switch the water back on and test the bath for leaks.

Our estimate:

1–2 days
£200 labour costs

You can expect to pay between £125 to £230 for this job, and it should take your plumber or fitter less than a day, assuming all goes well. In cases where the bath is being repositioned, the work may take a little longer and cost a little more.

Freestanding Baths

In the case of freestanding baths (such as roll tops or circular baths) the fitting will obviously be a little different. Many of these baths are made from stone or cast iron and as such, the floor structure may well need to be reinforced before the bath is fitted to ensure it can withstand the weight.

Taps are also likely to be floor or wall mounted, as opposed to being fitted to the bath itself, and rather than sitting within a supporting frame, the bath will be secured to the floor by its feet or other attachment.

In the case of Jacuzzi or whirlpool baths, there will be some additional wiring involved along with the plumbing, and so costs for the installation will be higher.
