When it comes to determining the price of a bathroom renovation there are two main considerations: is this an “out with the old, in with the new” renovation, or some sort of room conversion into a bathroom? Below is table of the different types of bathroom renovations and the price you’d expect to pay.

Renovation Type	Material Cost	Labour Cost
Basic bathroom renovation – old fixtures out, new fixtures in. Like for like with no moving about, and no tiling or flooring	£500 to £1000	£300 to £500
Regular bathroom renovation – this is the same as a simple renovation but includes removal of old tiling and flooring and installing new, as well as some electrical work, towel radiator installation, mirror and extractor fan	£900 to £1500	£750 to £1000
Full bathroom renovation – this involves the same as the regular, but includes relocating certain fixtures, so for example, the bath may be moved to another position, thus requiring additional pipework	£1000 to £1600	£900 to £1200
Extended bathroom renovation – this can be a combination of any of the above plus an internal wall being removed and an adjoining room being fully or partially converted into part of the bathroom	£1200 to £2000	£1500 to £2000
Conversion – This is in most cases the costliest new bathroom, as a regular room, often a bedroom, is being converted into a bathroom. Naturally, pipework is the sticking factor here. You need to be able to run waste pipes into the sewer system and it’s rarely as easy as you think	£1300 to £2200	£2000 to £2500

In all of the above cases, a skip (possibly two) will be needed so an additional £100 to £200 should be factored in.

Basic New Bathroom Cost

Normally, a new bathroom will cost in the region of £2000 with the main factors affecting the cost listed below:

• The size of your bathroom
• The bathroom fitters you hire
• The quality of materials and finish
• Your location

A bathroom renovation normally means removing the old toilet, shower, bath and sink, and replacing with new fixtures. It can also include removing old tiles and flooring and replacing these too, as well as installing towel radiators, mirrors and extractor fans.

Below is a breakdown of the costs you’d expect to pay for a regular bathroom renovation with low-priced fixtures and of roughly 9 sq. metres (3m by 3m):

Job	Labour & Supply Cost
Stripping the old bathroom of its fixtures, and removing waste	£250
Removing tiles from floor and walls and making good	£150
Laying new tiled flooring	£400
Fitting new tiles to walls	£600
Installing new bath	£350
Installing new shower unit and head	£400
Installing new toilet	£150
Installing new sink and taps	£200
Installing towel radiator – electric or plumbed	£150
Installing mirror	£30

New Bathroom Cost Calculator

From the above table we can come up with a rough cost for the cost a new bathroom per square metre. Obviously, a bathroom will only need one shower or bath, one toilet, one sink, one radiator, one mirror and one skip. As such, it's only the flooring, tiling and prepping that will scale. So, we have £1200 base cost for the bathroom fixtures, plus a scaling cost for labour and floor/tile materials of £125 per square metre.

To calculate the cost of your new bathroom, measure it's area (width x height), multiply this number by £125, and then add £1200

So, for example, if you're bathroom is 2m x 2m, so 4 sq. metres, then it will cost roughly - (£125 x 4) + £1200 = £1700.

Bathroom Renovation Quotes

As you likely already know, when carrying out any expensive home improvement work, it’s always best to obtain multiple quotes from local tradesmen. This lowers your risk of being ripped off and gives you a good indication of what you should be paying for the job. You may find one quote to be exceptionally cheap. This should be considered with caution.

Summary

Finding out how much your new bathroom will cost you is a fairly easy task, as the majority of the cost is going to be materials - your fixtures and your tiles. Once you've chosen which one's you want, the costs of these is easy to determine.

The labour costs are perhaps not as easy, especially in the case of bathroom conversions or fixture relocation. However, obtaining a few labour-only quotes should give you a clear idea, and this article should also give you a ball-park figure to keep in mind before you obtain any quotes.
