After going through the entire process, i have gathered a solid understanding of bathroom renovation costs in the UK.
In this post, I share my experience and insight helping you for your own renovation journey with a through understanding of bathroom refurbishment costs in 2025.
Understanding Bathroom Renovation Costs in the UK
Understanding the different costs involved is crucial for smoother and more successful bathroom renovations.
Here, we have discussed various elements involved when budgeting for your bathroom renovation in the UK.
Full Bathroom Renovations/ New Bathroom Costs in the UK
The cost of bathroom renovations highly depends on whether you opt for a full renovation, partial renovation, or a simple upgrade.
We estimate that, on average, a full bathroom renovation in 2025 can cost anywhere from £4,500 to £10,000. In case you choose top-of-the-range fittings and fixtures, the cost may even exceed £15,000. So, for the entirely new bathroom, you may expect to pay around £15000 to £25000, depending on the size of your bathroom and the type of fixtures you choose.
The cost varies significantly depending on the size of your bathroom. It’s obvious that the smaller the bathroom, the lower the costs will be. Other factors that influence the new bathroom costs are materials, cost of labour, and structural changes required.
Partial Bathroom Renovations: What to Expect
A partial renovation that requires only certain fixtures to be replaced without making any other changes may cost from £2,000 to £8,000.
It is significantly less than full renovations. You may only opt for the installation of a single fixture, like a new shower enclosure, or replace a toilet with a better one. The cost highly depends on the type and quality of the new fixture and the extent of changes required for installation.
Bathroom Upgrades: Cost-Effective Options
A simple bathroom upgrade in the UK may cost as little as £500 to £2,000.
It involves updating existing fixtures, refurbishing, or adding a new accessory requiring no structural or layout changes. The upgrade cost varies depending on the cost of repairs (if involved) and the types of new fixtures or accessories chosen.
