If you’re starting a bathroom renovation, cost is likely to be one of your biggest decisions to make. Setting a budget for a bathroom project can seem daunting and complex, not only because fixtures and fittings can be expensive, but because a bathroom design usually requires specialist skills that stretch beyond the ability of most DIYers. 

The cost of your bathroom renovation will depend on a number of factors, including:

  • How big the room is
  • The amount of renovation work needed
  • The quality of finish
  • The spec of materials you choose 

However, it’s possible to estimate an average cost based on an average bathroom renovation. You can expect the costs of a basic bathroom design to range from £3,000 to around £6,500. Larger spaces, those that need more renovation work and those that are using luxury products will see prices range from £7,000 - £15,000+

How Much Does it Cost to Fit a Bathroom?

When working out your bathroom renovation cost it is important to factor in fitting costs. Don’t forget labour costs, tiles, heated towel warmers, lighting and frames for baths to be built in to.

A plumber should be able to retrofit a bathroom in two or three days, as well as removing the old one — this would cost around £1,000.

To tile an average size bathroom would take one to five days. Costs of around £65/m² can be expected, although these prices will vary depending on the tiles and room size.

Your bathroom flooring has to look good, suit your chosen fittings but also most importantly has to stand up to water, humidity and be slip resistant.

The types of materials you choose will also affect the cost - you can choose from vinyl, ceramic, stone, engineered wood and even concrete.

How Much does a New Bath Cost?

  • Low end: from £80
  • Average cost: from around £300 to £700
  • Top end: Anywhere between £800 and £3,000

A standard bath size is 700 x 1700mm and this what most high street manufacturers will sell

If you buy a bathroom suite it's worth remembering that baths tubs tend not to be included (usually this only includes the WC and basin) so a bath is likely to be something you will need to buy separately.

The cost of a bath will depends on the material it is made from and whether it is a standard size or a more unusual size.

The very cheapest baths are usually made from thin acrylic and come ready to be built in to a frame, which can then be tiled or finished with a purpose-made bath panel which you will have to buy separately.

Cheap acrylic baths cost from around £80, but can be flimsy and easily crack, so do give them a thorough check before buying.

Not all acrylics baths are cheap though and those made from thicker, fibreglass-reinforced acrylic are of a much better quality. Acrylic also keeps the water warm for longer than steel.

Steel baths are perfect for those on a budget who want durability without the hefty price tag. They tend to be more hardwearing than very low-cost acrylic baths and often cost little, if any, more — starting from around £120.

Once you start looking at cast iron, timber, composite and stone, the prices rocket. However, if you want to make a statement in the bathroom this is the way to go. Prices for these baths start from around £600, but can reach prices of up to £3,000.

How Much is a New Shower?

  • Low end: £50
  • Average cost: £60 – £500
  • Top end: £500 – £2,000+

If you want to know how to choose a shower, then first look to electric showers. These are the cheapest option and are ideal for those looking to carry out a quick, low cost bathroom update.

Electric showers have a connection to just the mains cold water supply and heat water on demand. This means that they struggle to reach the level of power provided by power showers and those using stored hot water, although choosing one with a higher kilowatt rating will help.

On the plus side, they are economic to run, installation is straightforward and they start at around £50.

Bath/shower mixers are another good option for those looking to keep their bathroom renovation costs low, with prices from £50.

The shower hose and head are combined with the bath mixer tap and this is how the temperature is adjusted. They are easy and cheap to fit, but the pressure can be lacking and getting the water temperature right can be fiddly. 

  • A manual shower mixer (from £60) has the hose and spray coming out from a wall unit, with a temperature control to adjust the temperature.
  • Thermostatic mixers are similar to manual mixers but have a built-in thermostat that automatically adjusts the water temperature (but not the pressure) if a tap elsewhere in the house is being used. They start at £125.
  • Power showers start at £150 and are connected to an integral pump to boost flow rate. However, they are not compatible with combi boilers as they need a supply from both a cold water cistern and a hot water cylinder.

These are just the basic shower types. Digital showers, shower towers, columns and cabins all offer a luxury showering experience, with a multitude of sprays and jets — at a cost of course, from £250 upwards.

How Much do Shower Enclosures Cost?

  • Low end: from £100
  • Average cost: £120 – £300
  • Top end: £550+

The cost of a shower enclosure depends on its configuration and materials.

Basic shower enclosures featuring one glass side panel and a door, or a quadrant enclosure with double doors, can cost as little as £100.

Don’t forget, however, that you still need to factor in the cost of a shower tray, which will cost from £60 at the lowest end.

A complete ‘wet room‘ style enclosure, complete with walk-in tray and frameless shower screen will cost from £550. A frameless fixed enclosure, with no door, will start at around £200.

Wet room kits can also be purchased. These come complete with  everything you need to form a platform, drainage and waterproofing equipment (but excluding tiles) — they cost around £500-£600.

  • Average cost: £60 – £150

From as little as £50 you can pick up a ceramic pedestal basins.These are also convenient in that all pipework can easily be concealed behind the pedestal.

If you are after a more contemporary basin, consider a semi-pedestal or wall-hung basin. These basis cost from around £60. Remember that a wall hung basin will require a stud wall to be constructed from which to hang it and conceal the pipework.

Basins designed to sit in or on top of a vanity unit (including freestanding basins and semi-recessed models as shown above) allow for useful storage beneath. These basins cost from £90, but remember to factor in the cost of the unit they sit on or in, too.

While most basins are ceramic, glass, metal and stone are all options but cost more. The most common basin size is 550mm x 400mm.

How Much Does a Toilet Cost?

  • Low end: From £50
  • Average cost: £200 – £400
  • Top end: £500

Floor-mounted, low-level WCs cost from £50. Traditional-style high-level toilets are another option, as are more modern-looking wall-mounted WCs — here the cistern and pipework is typically concealed within a frame in a studwall.

How Much will New Taps Cost?

Pillar taps (taps with a separate tap for hot and for cold) are the cheapest type of tap, costing from £30 per pair. 

Mixer taps that have separate controls for hot and cold flow tend to be next up the scale, from around £45, with monobloc mixers (where flow and temperature are both controlled from one lever) usually at the top, from £50 up to the low £100s.

Your choice of sanitaryware will affect which taps you can have. Counter-top, bowl-style basins, for example, will require wall-mounted taps or those set into a vanity unit, while freestanding baths will need wall- or floor-mounted taps. 

These can be more costly than simple mixer taps located on the bath or basin, both to buy and fit.
