Bathroom Supply & Installation
A bathroom built from the substrate up
We supply and install bathrooms, en-suites and shower rooms across Sheffield, Chesterfield and Rotherham. Whether you're replacing a dated suite, converting a bath to a walk-in shower or adding an en-suite to a loft conversion, the job is handled by one accountable builder.
Bathrooms are where poor workmanship shows fastest. Water finds every weak joint, and a leak behind tiles can damage ceilings and timbers below long before you see it.
That's why the preparation matters most: sound floors, properly boarded and waterproofed walls in wet areas, correctly falling waste pipes and well-sealed junctions. Those are the steps that get skipped when a job is rushed.
Because Garry is a builder with 45 years' experience, the job can include moving walls, relocating the bathroom, strengthening floors for heavy baths or adding new drainage.
Don't leave it to chance
What happens when a bathroom is installed badly
The damage from a bad bathroom fit is usually hidden, until it isn't.
Leaks into the ceiling below
Failed seals and poorly connected wastes let water into the floor void, staining ceilings and rotting joists.
Cracked and loose tiles
Tiling onto unsuitable or flexing surfaces leads to cracked grout and tiles coming away, letting water behind.
Mould and condensation
Without adequate extraction, moisture builds up, leading to black mould and peeling paint.
Slow drainage and smells
Waste pipes without enough fall drain slowly and can trap debris and odours.
Common mistake: tiling over problems
Tiling over old tiles or damp plaster hides the problem rather than fixing it, and the new bathroom fails early.

In detail
Bathroom types, materials and installation methods
The right approach depends on the room, the people using it and the look you want.
Family bathrooms
Typically a bath, basin and WC, often with a shower over the bath. Good layout planning makes the most of small rooms common in Sheffield semis and terraces.
Walk-in showers and wet rooms
Replacing a bath with a large walk-in shower is popular for easier access. A full wet room needs the floor laid to falls and fully waterproofed, preparation is everything.
En-suites and shower rooms
En-suites often go into loft conversions or by borrowing space from a bedroom. Waste routes are planned first so the toilet and shower can drain correctly.
Walls, floors and waterproofing
Wet areas are boarded with moisture-resistant or cement-based boards and waterproofed before tiling. Floors are checked for movement and over-boarded where necessary so tiles don't crack.
Tiling and finishes
Porcelain and ceramic tiles are hard-wearing; large-format tiles need very flat surfaces. Grout and silicone are chosen for wet areas and applied to stay sealed.
Accessibility
Level-access showers, wider doorways and grab rail positions can be built in, making the bathroom easier to use as needs change.
Bathrooms in lofts and extensions
A new bathroom inside a loft conversion or extension is designed alongside the structure. Floor joists are sized to carry a filled bath, waste pipes are routed with the right fall to the existing soil stack, and ventilation is planned in from the start. Building it in this order is far simpler than retrofitting a bathroom into a finished room.
Replacing a dated suite without starting from scratch
Sometimes the layout already works and only the suite, tiling and finishes need replacing. Even then, the old tiles and boards are removed so the walls can be checked and prepared properly. It's the only way to know the new bathroom is going onto a sound, waterproof surface rather than hiding old problems behind new tiles.
Choosing the right shower
Electric showers heat water on demand and work independently of the boiler. Mixer showers take hot water from your system and need adequate pressure. Where pressure is low, a pump may help on some systems. Garry will check what your home can support before you choose.
Storage and layout in small bathrooms
Wall-hung vanity units and toilets free up floor space and make cleaning easier. Recessed niches in shower walls remove the need for shelves. In small rooms common across Sheffield, moving the door or swapping the bath for a shower can make the room feel twice the size.
Heating
A heated towel rail keeps towels dry and helps reduce condensation. Underfloor heating can be laid beneath tiles to keep the floor warm. Both are easiest to plan at the start of the job rather than added later.
Lighting and electrical safety
Bathrooms are divided into electrical zones, which control what fittings can go where. Lighting, extractor fans and shaver points need positioning to meet those rules, and electrical work is carried out to the regulations that apply.
Working with Garry on your bathroom supply & installation
When you contact GT Travis Builders about bathroom supply & installation, you speak to Garry Travis, the builder who will run the job. He has 45 years of hands-on experience in the trade, and he'll visit your home free of charge to look at the work in person rather than quoting from a phone call.
After the visit you get a detailed written quotation. Pricing is bespoke to your property, with no set packages, so you're only paying for what your home actually needs. Payments are made in stages as the work progresses, which means your money follows completed work.
If drawings or structural calculations are needed, Garry works with trusted architects and structural engineers. If you already have plans, he builds to them. Where building regulations apply, he coordinates with building control officers throughout and manages the job through to final sign-off.
Before any work starts, Garry explains the order the job will run in, what will happen on each stage, and what you'll need to do, such as clearing rooms or choosing finishes, so there are no surprises once work begins. If anything unexpected is found once the job is underway, he explains it and the options before any extra work goes ahead.
