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.
| Feature | Wet room | Walk-in shower | Bath-to-shower conversion |

| What it is | A fully waterproofed room with a level shower area | A low-profile tray with a fixed glass panel | Your old bath removed and a shower fitted in its place |
| Step-free access | Yes, the floor is fully level | A low step at the tray | A low step, or level if a level-access floor is fitted |
| Waterproofing | Full tanking of the floor and walls | Around the shower area | Around the new shower area |
| Floor work | Floor formed with a fall to the drain | Little or none | Bath area made good for the new tray or floor |
| Fitting time | The longest of the three | Usually 1 to 2 days for the shower alone | Usually 2 to 3 days |
| Best for | Step-free access and a minimal look | Smaller bathrooms and shower rooms | Homes where the bath is rarely used |

Why us
Choosing a bathroom fitter comes down to three questions: who will be in your home, what it will really cost, and what happens if something goes wrong. Here is how we answer each one.
Your bathroom is fitted by our own team, and electrical work is carried out and certified by a registered electrician we work with. One project manager is your single point of contact from the free survey to handover.
Founded by James McCallum, Glasgow Bathroom Fitter has spent 15 years fitting bathrooms in homes across Glasgow and Renfrewshire, from sandstone tenements to modern family houses.
After a free survey you receive a competitive, fixed-price written quote with no hidden extras. A deposit secures your start date, and the balance is paid on completion.

Pricing
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.

Local expertise
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 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.
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 guideTop-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.

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.
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.
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.
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.
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.
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.
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.
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.
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.
