Bathroom Renovations in Walthamstow
A bathroom is a small room with more trades per square metre than anywhere else in the house: demolition, plumbing, electrics, carpentry, tanking, tiling, glazing and decoration all inside a few weeks. Get the sequence or the waterproofing wrong and the failure shows up on the ceiling below a year later.
Walthamstow's Victorian terraces have been a loft and rear extension hotspot for a decade, with well-established local precedents for planning applications.
That context shapes how we approach bathroom renovations here. A mix of tight terraced streets and managed developments; in blocks we work to building management rules on lift use, delivery windows and noise hours. We survey the property, confirm the consents that apply to E17 and issue a fixed price against a written scope, so the figure you sign is the figure you pay unless you change the brief.
Our indicative rate for bathroom renovations in East London is around £9,690 per unit, reflecting a ×1.02 area factor against our London baseline. Use the instant quotation tool for a figure tailored to your size, specification and start date.

How the job runs
Design and specification
Layout, setting-out, tile sizes and every fitting selected and ordered before we start, so the room is not held up by a two-week lead time.
Strip-out
Existing suite removed, floors and walls checked for rot, damp and joist condition.
First fix
Pipework, wastes, wall-hung frames, electrics and extraction installed and pressure tested.
Waterproofing
Boarding, tanking membrane, shower former and underfloor heating laid and tested.
Tiling
Levelling, tiling to the setting-out plan, grouting and silicone.
Second fix and handover
Sanitaryware, brassware, screens, accessories, commissioning and a certified electrical installation.
Waterproofing is the whole job
Tiles and grout are not waterproof. Water passes through grout lines, and the layer behind them is what protects the structure. We use cement or foam backer boards rather than plasterboard in wet zones, apply a liquid or sheet tanking membrane with taped joints at every corner and pipe penetration, and form shower floors with a purpose-made tray or a graded former.
That detail is invisible when the job is finished, which is exactly why it is the first thing to be cut on a cheap quote. On a first-floor bathroom over a living room it is the difference between a beautiful room and a five-figure insurance claim.

How long does a bathroom take?
2–3 weeks for a standard replacement in the same layout, 3–5 weeks for a full wet room or where the layout moves and the floor is rebuilt.
How much does a London bathroom cost?
Our indicative starting point is around £12,500 for a complete bathroom including strip-out, services, tanking, tiling and mid-range sanitaryware. Natural stone, bespoke joinery and premium brassware push it higher.
Can I have a wet room upstairs?
Yes, with the right build-up. We either recess a former between the joists or step the floor up slightly to build the fall, and fully tank the room. A structural check on the joists comes first.
Is underfloor heating worth it?
In a bathroom, yes. Electric mat heating is inexpensive to install as part of a refit, dries the floor quickly and frees wall space.
