Walk-In Shower Cost UK
Fit-only installation of a client-supplied walk-in shower starts from £3,500 where it's the main work in an existing bathroom and the waste position stays where it is. Moving the waste, fitting a fully level floor, or a non-rectangular glass opening all add to that figure. A £125 survey gives you an exact, written number.
What moves the price
A walk-in shower is simple in concept — a glass panel, a tray or level floor, and a valve — but each of those three elements has a cheaper and a more involved version, and it's the combination that sets the final figure.
| Factor | Why it moves the price |
|---|---|
| Reused vs moved waste | Keeping the drain where it already is avoids altering supply and drainage runs. |
| Low-profile tray vs level floor | A flush, level floor needs the same fall-to-drain and full tanking as a small wet room. |
| Glass panel shape | A square opening is quicker to measure and fit than a non-square wall or an angled layout. |
| Concealed vs exposed valve | A new concealed valve means opening up the wall; an exposed valve on an existing supply is quicker to fit. |
| Wall finish | Natural stone takes longer to cut, seal and fit around the panel fixings than large-format porcelain. |
A realistic scenario
The most common job we see is a bath-to-shower conversion: an existing bath is stripped out, the waste position is reused since it already sits in roughly the right place, a low-profile tray goes down, and a rectangular glass panel is fitted to a wall that's being re-tiled in large-format porcelain at the same time. That's close to the entry-level figure, because none of the higher-cost drivers above apply.
Where the brief changes — the shower moves to the opposite wall, the floor needs levelling to remove the step entirely, or the opening isn't a simple rectangle — each of those adds its own first-fix, tanking or glass-fitting time on top of that baseline, which is why two walk-in showers that look similar in a photo can price quite differently once the survey measures the actual room.
At the upper end, a full stone-clad walk-in with a new concealed valve, a digital shower controller, and a bespoke-cut glass panel on an angled wall sits well above the entry-level figure — not because any single element is exotic, but because the concealed valve means opening the wall, the digital controller needs its own commissioning, and an angled panel takes longer to template and cut accurately than a square one. None of that is a reason to avoid the specification; it's simply what each extra element genuinely adds in first-fix and fitting time.
Shower size and room footprint
A common question is whether a bigger shower simply costs more in proportion to its size. It doesn't scale that cleanly. Most UK walk-in showers sit somewhere between a 900mm × 900mm opening and a 1400mm-wide run against one wall, and within that range the tanking area and glass panel size move only modestly — a 1200mm panel isn't dramatically more expensive to cut and fit than a 900mm one. What genuinely changes the price is the shape of the opening and whether the floor is flush, not the few hundred millimetres of difference between a compact and a generous tray.
In a genuinely tight footprint — a small en-suite or a converted box room — there often isn't enough width for an open walk-in panel plus the splash-guard distance it needs on its open side. A hinged door on a framed or semi-framed enclosure makes better use of that space, which is why we'll sometimes recommend a door over an open panel at survey even when a walk-in look was the original brief.
How this differs from a wet room
A walk-in shower and a wet room are often confused, but the floor construction is what actually separates them. A walk-in shower can sit on a shallow tray with a small upstand, which is a quicker, less invasive job than removing a step entirely. Once the floor is flush throughout the room with no upstand at all, it's priced and built as a wet room rather than a walk-in shower — see our wet room cost guide for that distinction, or our wet room vs walk-in shower guide for a fuller comparison.
What's included in the fit-only price
The figure above covers labour only — strip-out of the old fixture, first-fix plumbing, tanking to the shower zone, tiling, and fitting and commissioning the glass panel, valve and tray or floor. The glass panel, valve, tray, and wall and floor tiles are bought separately by you, which is different from a supply-and-fit quote where a retailer or contractor bundles the goods and labour into one number.
Worth budgeting for separately either way: skip hire or waste removal for the old enclosure and tiles, and making good any surrounding decoration disturbed by new pipework. Neither is usually included in an installation quote from any installer, fit-only or otherwise.
Sources and standards
Tanking and tiling practice referenced in this guide follows BS 5385 (wall and floor tiling). This figure is specific to a walk-in shower installed as the main work within an existing bathroom; for a full room re-fit, see our bathroom installation cost guide.
Frequently asked questions
Usually a little more, because the glass panel is typically a larger, sometimes bespoke-cut piece and the floor area under and around it needs the same tanking standard as any shower, with no frame to help mask a slightly imperfect wall line. The gap is modest rather than dramatic — it's the glass and the wall prep that move the price, not the fitting itself.
Often yes, if the existing waste and supply positions can be reused. Reusing the existing drain position keeps the job closer to the entry-level figure; moving the waste to a different wall adds first-fix plumbing time.
Either is possible. A shallow low-profile tray keeps a small upstand and is usually quicker to fit; a fully level, flush floor is effectively a small wet room and needs the same floor-fall and tanking work as one, which is priced accordingly.
There's no single standard size — panels are cut to the opening. Larger or non-rectangular openings (a wall that isn't quite square, for example) take longer to measure and fit accurately than a straightforward rectangular opening, which can add to the price.
Yes. The survey checks the wall and floor substrate, water pressure and flow, the achievable waste position, and the exact opening the glass panel needs to be cut to, before you order anything.
Sometimes, if the existing valve is in good working order and its position suits the new layout. We'll check this at survey — reusing a sound valve avoids unnecessary cost, but concealed valves buried in a wall that's being opened up for other work are usually replaced at the same time since the wall's already open.
Less than most people expect. A common UK shower tray footprint is around 900mm × 900mm to 1200mm × 900mm, and within that range the glass panel and tanking area scale up only modestly. What moves the price more is the shape of the opening and the floor construction, not the few hundred millimetres between a compact and a generous tray size.
A 900mm-wide opening is usually the practical minimum for a genuinely open walk-in feel rather than a disguised cubicle. Below that, a hinged door on a framed or semi-framed enclosure typically makes better use of a tight footprint than an open glass panel, since a walk-in shower needs splash-guard distance on the open side that a door doesn't.
Yes, particularly the level-floor version — removing the step is one of the most common accessibility adaptations we fit. See our building regulations and planning guide for what Part M covers, or our accessible bathrooms page for the fuller picture on grab rails, seating and wider doorways.
