How much does a new bathroom cost? A sparkly, new bathroom is always high on self builder's and renovator's wish lists but it can be hard to know what you will need to budget for this project.
So, what are we looking at in terms of costs in 2023? You may be wanting a budget upgrade for your existing home – in which case your focus will be on bathroom renovation costs – or maybe it is a top-of-the-range bathroom for your brand-new self build you are after — these will naturally be poles apart in terms of cost.
Here, we look at the average prices you should expect to budget for, together with installation costs and a host of factors that will influence the overall cost of your new bathroom.
These factors are key to understanding how and where your budget can be affected and where you can save or spend to achieve your dream bathroom.
How much does a new bathroom cost?
In general, bathroom design consists of a toilet, basin, bath and shower, which come in all sizes, shapes, finishes and, of course, costs. If you’re planning a complete bathroom renovation, to include removal/disposal and replacement of the suite, radiator, floor and wall tiles, plus new lighting, extractor fan and decorating, you can expect to pay on average around £7,000.
If you’re self building, you won’t have any of the costs of removal and disposal. While you’ll need to introduce the waste, piping, electrics and structure of the room, this will be built into your overall build cost/m. So you can expect your new bathroom to come in below the average renovation budget of around £7,000.
As with kitchens, the variable cost range is huge for bathrooms. You can get a basic toilet, basin and straight bath for under £300, or easily spend between £10,000 and £15,000+ for high-end designs and state-of-the-art features.
Which elements make up bathroom costs?
Whether you’re renovating or self building, there’s a host of factors that can reduce or increase your costs so it helps to break each element of a new bathroom down and look at the associated costs separately. The main elements include:
- Professional services, such as plumber, tiler and electrician
- Wall and floor tiles
- Shower and brassware
How much does plumbing for a new bathroom cost?
When renovating a bathroom, for removing and installing a typical suite to the same layout, you can expect to pay approx. £1,250 to £1,500. In the case of self builds, you will save the removal costs (£150-£200) and should also save on overall plumbing costs across your build, when you factor in your kitchen, utility, en suites etc.
Reconfiguring the layout on a renovation will add to costs. New pipework will be needed, floor and wall finishes will most likely need to be renewed and if you’re relocating your toilet, moving soil stacks can be particularly expensive, adding a few hundred pounds to your plumbing installation costs.
What do bathroom electrics cost?
You may just need a new ceiling light fitted (£50-£100), but most modern bathroom ideas incorporate many electrical options: extraction fans, power showers, dual fuel heated towel rails, shaver points, under-cabinet and mirror lighting — even waterproof TV screens.
Expect electrics to cost on average £800 to £1,200.
If you’re introducing or moving lighting for cabinets/mirrors, shaver sockets or extraction fans you’ll have additional electrical costs for chasing out and installation and redecoration costs.
How much will my sanitaryware cost?
The vast range of options means your individual choices will significantly impact costs — while there are cheap bathroom suites out there costing as little as a couple of hundred pounds, there are also those that will set you back thousands. For example, you can get a budget straight bath for around £100, but you can also spend upwards of £4,500 on a Whirlpool bath.
If you want to get a general idea of how much individual sanitaryware costs, we have put together this quick guide:
- Basin: From £50 to £300+
- Bath: Fro £80 to £5,000+
- Toilet: From £50 to £500+
How much should I budget for bathroom tiles?
Tiles cost from as little as £5/m2, but if your budget permits, you can also pay over £200/m2 for designer glass tiles.
Really think through your bathroom floor tile ideas — the more complex the tile laying pattern, the longer it takes to complete, pushing labour costs higher than for the same area with a simpler pattern. If you’re tiling a large area, costs will naturally rise, but you can save money by choosing larger format tiles, as they are quicker to fit. Patterns such as herringbone will also need a lot more cuts, so wastage allowances should be increased from 10-15% to 20%.
Don't forget to account for labour costs if you plan on using a tiler. If you want to fully tile your walls and floor, you can expect to pay, on average, between £800 to £1,500 depending on the size of your bathroom.
How much will underfloor heating add to bathroom costs?
If you’re introducing underfloor heating, the costs installed for a self build are around £20-40/m2. This is usually included in the build process and it’s the least expensive/best time to install it.
On renovations, the costs will be higher to retrofit (around £40-60/m2) and will be impacted by the nature of your existing floor. It can be expensive if floors need to be taken up and even the lowest profiles will require costly adjustments to doors and skirting.
Add the cost of a decoupling membrane to prevent your new tiles cracking if you’re tiling on new concrete screeds or suspended floors.
How much do wet rooms cost?
If it is wet room ideas that you are budgeting for, costs will be a little different.
The walls and floor will need to be completely waterproofed by a ‘tanking’ process, using tanking kits or waterproof boards, together with specialist shower trays/ flooring gradient.
Expect labour costs of around £1,800 for installing a wet room.
How much is the average bathroom design fee?
Simple design advice consultations cost around £300 but if you’re looking for a full design with plans for your builder, this can increase to around £2,500.
Look out for companies providing free, no-obligation bathroom designs if you want to minimise costs.
