The most expensive bathroom in Glasgow is one you have to pay for twice. A bad fitter does not just leave you with a tired-looking room, they often leave you with a leak, a failed waterproof system and a remedial bill that equals the original quote.
This is the most read article in our complete guide to bathroom fitting in Glasgow for a reason. Here is what to do, and what to avoid.
Before you even ask for a quote
Spend ten minutes writing down what you actually want. A short brief stops you from being talked into the fitter's preferred suite rather than the bathroom you wanted. Include rough budget, must-haves, nice-to-haves, and anything you specifically do not want.
Where to find candidates
There are three honest routes.
- Personal recommendation from someone whose finished bathroom you have actually seen. Single best source.
- A vetted matching service like Stonewater, where the checks have been done before you arrive.
- Trade associations such as Trustmark or local chapters of the Scottish and Northern Ireland Plumbing Employers Federation, which at least filter for some baseline standards.
We would gently warn against picking a name purely from a generic directory site or a Facebook ad. The bar to appear there is paying for the listing, nothing else.
Questions to ask every shortlisted fitter
- Are you insured? Public liability insurance, minimum two million pounds, ideally five. Ask to see the certificate.
- Can I see two real previous bathrooms? Photos are easy to copy. A live address you can drive past, or a recent customer who will take a call, is harder to fake.
- Who is actually doing the work? If the quoter is not swinging the hammer, ask who is, and what their experience is.
- What is subcontracted? Tiling, electrics and plastering are commonly subcontracted. That is fine, but you should know who is responsible if something goes wrong.
- How do you handle variations? A good fitter quotes variations in writing before the work happens, not as a surprise on the final invoice.
- What waterproofing system do you use and why? A vague answer is a problem. See bathroom waterproofing and tanking.
- What is your snagging process? Every job has snags. The difference is whether the fitter expects to come back and put them right.
- How long is your guarantee, and is it honoured in writing? Spoken guarantees disappear with the van.
Paperwork to insist on
- Written quote that itemises labour and materials separately.
- Clear scope of work, including what is included and what is specifically excluded.
- Payment schedule tied to milestones, not large up-front deposits.
- Insurance certificate, current, not expired three years ago.
- For electrical work, confirmation that a registered electrician will certify the installation.
- Written guarantee covering workmanship for a defined period after handover.
Red flags to walk away from
- Cash-only working. Removes paper trail and almost always removes insurance protection too.
- Large deposit demanded before any work starts. A modest materials deposit is fine. Fifty percent up front is not.
- No written quote. A handshake number on the back of a business card is a future dispute.
- Pressure to decide today. Any decent fitter is happy for you to compare quotes.
- Vague answers on waterproofing or extract. These are the parts that cause expensive failures later.
- Refusing to provide references. The only reason to refuse is that there are none worth giving.
Comparing quotes properly
Cheap quotes almost always exclude something. Common omissions include waste removal, snagging visits, electrical certification, the cost of moving the soil pipe, or any tanking. When you compare quotes, compare scope first and price second.

What Stonewater does for you
Doing all this yourself, on every quote, is a job. Stonewater Bathrooms is a Glasgow service that has already done it. Every fitter in our network is reference checked, insurance checked and quality checked before they join us. We keep checking, with feedback after every job. When you submit a quote request, we match you with a vetted local fitter who covers your postcode and we stand behind that match.
We work right across Glasgow and the surrounding towns, including Bearsden, Giffnock, Rutherglen and East Kilbride.
One last test
If you only ask a fitter one thing, ask this. "If I have a problem with the bathroom in twelve months, how will you handle it?" A trustworthy fitter has a clear, calm answer. An unreliable one changes the subject.
