If you ask most people how much a new bathroom should cost, you’ll usually get a number that’s… just a little bit optimistic. We hear things like: 

“I saw a suite online for £1,200.” 
“My mate down the pub says he can fit it for a couple of grand.” 
“Bathrooms can’t be that complicated, can they?” 

And yet, when the final quote lands at £12k, £15k, or more, the reaction is often shock. Not because the customer is unreasonable, but because they’re only seeing part of the picture. Bathrooms are one of those projects where a huge chunk of the cost is hidden behind walls, under floors, and inside the business keeping everything running.  

At Alan Heath and Sons, we believe in being open and honest about pricing, so let’s talk about what actually goes into bathroom pricing and why it adds up the way it does! 

The visible vs. invisible costs of bathroom renovations 

Most customers base their budget on what they can see. Things like the bath, the toilet, the vanity unit, the tiles, and the shower. 

Those are the visible costs, and they matter (obviously!) but they aren’t the only thing that goes into pricing. What you don’t see includes things like: 

• Tile adhesive, grout, levelling compound 

• Ply boarding floors and walls 

• Waterproofing systems and tanking 

• Pipework, wiring, valves, traps, fixings 

• Screws, sealants, membranes, insulation 

• Skip and rubble bag costs 

Individually, these items don’t feel expensive, but collectively, they add up fast. A few bags of adhesive here, a roll of membrane there, and suddenly you’re into hundreds or even thousands of pounds that never appear on Instagram photos. 

Overheads you don’t see 

When customers compare a professional bathroom company to “a guy with a van,” they’re rarely comparing like for like. Established installers and retailers carry overheads that don’t show up on a quote as a single line. These are things like: 

• Vans (purchase, fuel, maintenance, insurance) 

• Public liability and professional insurance 

• Showroom rent (we own our own building, so that doesn’t affect us), utilities, and upkeep 

• Office staff and admin time 

• Design software and planning tools 

• Accounting, compliance, and warranties 

• Tool replacement and calibration 

These costs are what allow a business to turn up on time, answer the phone, fix problems if they arise, and still exist five years down the line if you need support. When you pay a professional rate, you’re not just paying for today, you’re paying for reliability and accountability. 

Why bathroom renovation labour costs what it does 

This is where expectations and reality often clash hardest. Skilled bathroom fitting isn’t just “a bit of plumbing.” It’s plumbing, electrics, carpentry, tiling, waterproofing, problem-solving, and sequencing, all done in the right order, to regulation, in a confined space that wasn’t built perfectly to begin with. 

Good tradespeople: 

• Train for years 

• Invest heavily in tools 

• Keep up with regulations 

• Fix surprises without panicking 

• Take responsibility when things go wrong 

That’s why their day rate isn’t the same as “mate down the pub” pricing. Cheap labour might look really tempting upfront, but it often costs more later in the form of repairs, leaks, re-tiling, or even ripping everything out and starting again. 

What to take away from all this 

If you’re planning a bathroom, a few things help keep expectations realistic: 

• Ask for a clear breakdown of costs 

• Compare like-for-like quotes, not just the headline number 

• Think about how long you want the bathroom to last 

• Factor in quality, reliability, and aftercare, not just price 

Years ago, a client compared us to an orchestra, which made no sense to us until they explained further. All of the musicians in an orchestra know how to play their instruments but having them all play together well is the key. The client went on to say that we “play” very well together because we all work as a team. This is where the guy down the pub may not be the same. 

If you’re planning a new bathroom and want to understand what you’re really paying for, a proper conversation makes all the difference. At Alan Heath & Sons, we take the time to explain the costs, the process, and the options, and then get on with doing the job properly. If that sounds like what you’re looking for, get in touch and let’s talk it through.
