Wet room, walk-in shower or bath-to-shower conversion?

The right choice depends on how step-free you need the shower to be and how much floor work your bathroom can take. A wet room gives fully level access, a walk-in shower suits most bathrooms, and a bath-to-shower conversion reuses the space where your bath sits now.

Pricing

How much does a new bathroom cost in Glasgow?

The cost of a new bathroom in Glasgow depends on five things: the size of the room, whether the layout changes, the suite and tiles you choose, how much repair the existing room needs, and access to the property. Because no two bathrooms are alike, we price every job individually and give you a competitive, fixed-price written quote after a free survey.

What affects the price

  • Room size and layout: moving the toilet, bath or shower means new pipework and drainage.
  • Suite, tiles and finishes: large-format porcelain, freestanding baths and underfloor heating cost more than standard ranges.
  • Condition behind the tiles: damaged plaster, rotten joists or old pipework must be put right first.
  • Wet room tanking: level-access floors need waterproofing and a correctly formed fall.
  • Property type and access: upper-floor tenement flats and tight stairwells take more planning.

Local expertise

Bathroom expertise for West of Scotland homes

Homes in Glasgow and Renfrewshire come with their own challenges, from sandstone tenements to Scottish building regulations, and planning for them early keeps your project on time and on budget.

Tenement flats

Tenement bathrooms often mean narrow rooms, shared soil stacks, lath-and-plaster walls and older floor joists. We plan around all of them and can advise on speaking to your factor and neighbours before work starts.

Building warrants

A like-for-like bathroom replacement usually doesn't need a building warrant in Scotland, but moving drainage, structural changes or creating a new bathroom can. We'll tell you at the survey whether your plans need one.

Building warrant guide

Water pressure & ventilation

Top-floor flats can have low water pressure, and Scottish homes need good ventilation to prevent condensation and mould. We'll recommend the right shower and extractor fan for your property.

FAQs

Bathroom fitting questions, answered

Can't see your question? Call 0141 280 9490.

How long does it take to fit a new bathroom?

Most bathrooms we fit take 5 to 10 working days from strip-out to handover. A straightforward bath-to-shower conversion is often quicker. Wet rooms and layout changes take longer, because tanking needs time to cure and new pipework or drainage has to be planned and fitted. We talk through the expected timescale for your bathroom at the free survey, so you know how long the room will be out of use.

Do you supply the bathroom suite and tiles?

Yes, we can supply and fit everything, from the suite and shower to the tiles and flooring. If you have already bought your own suite or tiles, our fit-only service installs them for you instead. We also take on tiling-only jobs for walls, floors and shower areas. Whichever option you choose, our own team does the work and you get one fixed-price written quote after a free survey.

Do you fit bathrooms in tenement flats?

Yes, we fit bathrooms in tenement flats across Glasgow and Renfrewshire. Tenement bathrooms are often narrow, share a soil stack with the flats above and below, and sit on older floor joists. We plan the layout around these limits before any work starts. We can also advise on speaking to your factor and neighbours, which helps the job run smoothly in a shared building.

Do I need a building warrant for a new bathroom in Scotland?

Usually not, if you are replacing a bathroom like for like. A building warrant from your local council can be needed if you move drainage, make structural changes or create a brand new bathroom, such as an en-suite. The answer depends on your plans, so we check them at the free survey and tell you whether a warrant is likely to be needed before you commit.

How much does a bathroom renovation cost?

The cost depends on your bathroom, so every job is priced individually after a free survey. The main factors are the size of the room, whether the layout changes, the suite and tiles you choose, the condition behind the old tiles and access to the property. You receive a competitive, fixed-price written quote with no hidden extras, and the price only changes if you change the plan.

Is your work guaranteed?

Yes, every installation carries our 2-year workmanship guarantee from the day the job is finished. The products we fit, such as suites, showers and taps, are also covered by their manufacturers' warranties. Any electrical work also comes with a certificate from our registered electrician. Because we manage the whole job, you deal directly with us if you ever need to use the guarantee, rather than chasing separate trades.

How do payments work?

You pay a deposit to secure your installation date, and the balance is paid when your bathroom is complete. Before that, you receive a fixed-price written quote after a free survey, so you know the full cost before you commit. The price only changes if you decide to change the plan, such as choosing a different suite or adding extra work to the job.

Can you adapt a bathroom for someone with limited mobility?

Yes, we install level-access showers, wet rooms, grab rails, shower seats and comfort-height toilets. These changes make it safer and easier to wash independently. Eligible adaptations for disabled people may qualify for VAT relief, and councils in Scotland can offer help through the Scheme of Assistance. We talk through the options that suit the person using the bathroom at your free home survey.

Which areas do you cover?

We cover homes within around 25 miles of our base in Johnstone, Renfrewshire. That includes Johnstone, Paisley, Renfrew, Erskine and Bishopton, most of Glasgow, Newton Mearns, Giffnock and Clarkston in East Renfrewshire, Bearsden, Milngavie and Bishopbriggs, and East Kilbride. If you are not sure whether we cover your street, call 0141 280 9490 or add your postcode to your quote request.

Who will be working in my home?

Our own fitters will be working in your home, and any electrical work is carried out and certified by a registered electrician we work with. You have one project manager from the free survey to handover, so you always know who to call with a question. Glasgow Bathroom Fitter was founded by James McCallum and has 15 years of experience fitting bathrooms in homes across Glasgow and Renfrewshire.
