Updated April 17, 2017

Bathtubs cost from between £130 to a high of £3,900 for a walk-in tub. Unless you're doing all the work yourself, labour costs will vary depending on location. In 2009, a standard estimate for labour costs was £975 and up to replace a bathtub and install ceramic tile.

Bathtub Materials

The least expensive typical bathtub material is steel, costing between £130 to £260, followed by fibreglass at £260 to £390, and cast iron, costing between £650 to £975.


Unless you're installing a freestanding tub, you'll need to consider the material surrounding the bathtub. Factor in the cost of the surround as well as the labour, unless you're doing it yourself. An average cost for a surround is between £130 to £260, and will vary depending on the size of the surround and the material chosen.The cost of tiling a surround will depend on the size, the type of tile chosen and the labour costs in your area.

Remodelling considerations

Will you need to cut a hole in the wall or damage the floor to remove the existing tub? Will you need new piping or additional floor joists? Can you use existing fixtures to cut down your costs or will you have to purchase new fixtures?

Water Heater Costs

If you're remodelling a bath and installing a larger tub, it may strain your existing hot water heater. You may need to upgrade your water heater or install a separate water heater. A typical gas or electric water heater costs between £130 to £260.


If you're doing the work yourself, make sure to study your local building codes.
