A bathroom in a Victorian or Edwardian terrace almost never occupies the room it was designed for, because most of these houses were never built with one. The scullery had a tin bath and a copper for boiling water; the WC, where there was one at all, sat in a lean-to at the end of the yard. Somewhere in the last hundred years, a bedroom got smaller, a return got built over, or a landing got boxed in, and that's the room you have now. It was never drawn for pipework, extraction or a shower tray, and every good bathroom we build starts by being honest about that.
This is what we've learned building bathrooms in these houses — three of the projects in our own portfolio, Bankside, Belgrave Road and Devonshire House, are bathrooms front to back — and what to look for in anyone you ask to build yours.
The room you're given
Most bathrooms in these terraces are small by any modern standard: a converted boxroom, a slice of a return, sometimes a space carved out under the eaves with headroom on one side only. The window, if there is one, is often small and awkwardly placed, because it was cut into a wall that wasn't planned around it. The first conversation is rarely about tile or taps — it's whether the room you have can be made to work, or whether a wall needs to move, a door needs to go elsewhere, or the layout of the floor above needs rethinking as part of a wider internal remodelling. We'll tell you which, honestly, before you spend money designing a bathroom that the room was never going to hold.
How do you fit a bathroom into a small Victorian terrace?
By setting the whole room out dry before anything is cut — tiles, niches, brassware and drain falls, planned on the actual walls and the actual floor, not a showroom drawing of a square room that doesn't exist in E17. On Bankside, a large-format porcelain bathroom specified by the client's architect, we dry-laid the entire floor first to plan the falls before a single tile was bedded, because the external corners were being mitred at 45 degrees with no trim anywhere in the room — the slow way, and the right way. On Belgrave Road, the rainfall shower head was set flush into the ceiling rather than wall-mounted, which meant the feed had to be run in exactly the right place before the ceiling went up. We laid that out with the clients before a single tile went on the wall. The cuts that end up at edges and corners are where the eye goes, and they're the ones a rushed set-out gets wrong.
What the floor and walls are actually made of
These are solid brick houses with no cavity, timber floors suspended on joists upstairs, and a lime or lath-and-plaster wall behind most of the tiling you'll ever see in one. None of that is a problem, but all of it changes what a bathroom is allowed to do. A wet room with a level, flush floor is straightforward on a solid ground floor. Upstairs, it depends entirely on what's underneath the boards.
Will a wet room work upstairs in a Victorian terrace?
Maybe. We can build up a fall in screed, lay a tray former, or in some cases drop the joists — but which of those is right depends on what the floor structure actually turns out to be once it's opened up, not what a floor plan suggests. We assess this on a site visit before quoting, never off a drawing. A full wet room isn't automatically the right answer for an upstairs bathroom in a hundred-and-thirty-year-old terrace; sometimes a low-profile shower tray does the same job without touching the structure at all, and we'll say so rather than sell you the more expensive answer by default. Where we do build in, walls and floors get tanked properly before a tile goes anywhere near them — the tanked, mirror-lined niche above the WC on Bankside is the same principle applied to a feature rather than a shower tray.
Ventilation and damp, taken seriously
A solid Victorian wall has no cavity to help moisture dissipate the way a modern wall does, which means a bathroom with poor extraction shows it faster here than it would in a newer house — usually as condensation on the coldest external wall first, then as the corner of a ceiling. These houses weren't built with mechanical ventilation in mind, so it's something we design in properly rather than treat as an afterthought once the tiling's finished.
How do you handle ventilation and damp in a period bathroom?
Properly, because it matters more in these houses, not less. Every bathroom we build gets effective extraction — typically a fan ducted to outside, on a humidistat, with a run-on timer that keeps clearing the air after you've left the room. Vented out of the building, not into the loft: we still find fans doing that often enough on other people's work that it's worth saying plainly. It's covered in more detail in what we've written about what hides behind the walls of a Victorian terrace — damp in these houses is rarely one dramatic problem and usually several small ones left unmanaged, and a bathroom is where that shows up first.
The details we mind
A bathroom is a small room, which means every decision in it is close to the eye and impossible to hide behind furniture the way you can in a living room. On Bankside, the external tile corners are mitred at 45 degrees rather than trimmed — two faces meeting at a clean edge, no aluminium bead breaking the line. On Devonshire House, the shower wall is Arabescato marble, the wall tile is an olive kit-kat laid vertically with a thin brass inlay running through it to break the run, and the cistern enclosure is tiled in the same kit-kat with a brass push-plate dropped into the front so the flush stays quiet and the wall stays continuous. On Belgrave Road, a deep teal hand-glazed ceramic is laid in stack-bond — straight vertical joints, no offset, which makes every cut unforgiving and the finished wall look considered rather than assembled — with a floating oak vanity hung on a steel sub-frame so the floor underneath stays clear and easy to keep clean. None of that is decoration for its own sake. It's what "premium" actually means when you stop using it as an adjective: specific choices, made because we'd want them in our own bathroom, and minded all the way through to the grout line.
Lit on purpose
Bathroom lighting matters more than most people plan for, and it's wired in before the boards go up, not decided once the room is finished and the socket's in the wrong place. We plan it with you: a wash light over the basin so shaving and make-up actually work, a feature light where the room can take one, dimmable downlights rather than one glaring central source. It's a small line item on a quote and one of the differences you notice every single morning.
Cost and timeline
A single bathroom in one of these houses — strip-out, replumbing, tiling and finishing — typically starts from £25,000, and the fuller picture of how that scales with a wider renovation is in our guide to what a renovation actually costs in East London.
How long does a bathroom renovation actually take?
Three to five weeks on site for a single bathroom, depending on tile complexity and any bespoke joinery. Belgrave Road, a straightforward family bathroom, took three weeks start to finish — the clients moved back in the same evening the dust sheets came up. Bankside, with mitred large-format porcelain throughout and a tanked feature niche, took five. Strip-out and first-fix plumbing move fast; tiling, and the time adhesive and grout need to cure properly, is usually what sets the pace, not the fitting itself. The full breakdown of how bathrooms compare to kitchens, extensions and whole-house projects is in how long does a renovation actually take.
Finished means finished
A bathroom is finished when the snag list is closed — grout lines consistent, the shower door hung true, the toilet roll holder within reach of where you're actually sitting — not when the last tile goes up and the van leaves. Good snagging is where a bathroom stops being an installation and becomes part of the house. Then we stay on the hook for twelve months, because that's what signing our name to the work means.
