Bathroom Refurbishment in Southwark | RCB Design & Build

Bathroom refurbishments are the fastest project type we run in Southwark — typically 3–5 weeks on site with a fixed price. RCB Design & Build delivers bathroom refurbishment projects right across Southwark (SE15) from our Dartford base — typically on site within 48 hours of enquiry, with a fixed written quotation in 5 working days. Our typical bathroom refurbishment project in Southwark costs between £9,000 and £29,000 in 2026, with most Georgian townhouses and modern apartments landing around £19,000. We are FMB, TrustMark, Checkatrade and TrustATrader accredited and operate as a Principal Contractor under CDM 2015.

Why Southwark homeowners choose RCB

Peckham and Dulwich drive strong demand for full refurbs and side-return extensions on Victorian terraces. Working out of London Borough of Southwark's area, we know the planners, the local building inspectors, and the named conservation officers — that personal relationship cuts weeks off the consenting timeline. Our typical Southwark project is on Georgian townhouses within easy reach of Dulwich Park or Southwark Cathedral, and we work with a small panel of trusted London-area subcontractors we have used for years.

What's included in our bathroom refurbishment price

Strip-out, replumbing to current pressure standards, electrical fan and lighting (Part P notifiable), waterproof board to wet areas, tiling, sanitaryware install, mastic and grout. Client supplies sanitaryware and tiles within agreed allowances. Our written quotation covers labour, first-fix materials, project management, scaffolding, skips, Building Control fees and statutory inspections. Second-fix materials (kitchens, bathrooms, flooring, tiles, paint, sanitaryware) are supplied by the client as a deliberate cost-control measure — this typically saves homeowners £1,520–£2,850 in trade markup. We exclude planning fees, party-wall surveyor fees and structural engineer drawings, which we coordinate at cost.

Southwark planning, party walls and Building Regs

Dulwich Estate properties carry restrictive covenants alongside conservation rules — get both reviewed early. Wet-room construction needs a fully tanked floor and a 1:80 fall to the gully. Get this wrong and you will leak into the room below within 12 months. Note that Southwark has multiple conservation areas — design must match prevailing materials, roof shape and fenestration. Party Wall Awards are typically needed for any excavation within 3 metres of a shared wall — we coordinate the surveyor and serve notices. Building Control is lodged at the start, with inspections at foundation, damp-course, pre-plaster and completion stages.

Timeline and process for Southwark projects

Bathroom refurbs run 3–5 weeks on site. Lead times on bespoke vanity units or feature tiles drive most schedule slip — order 6 weeks ahead. We hold a weekly call with the client throughout, send a written progress report with photos every Friday, and the lead PM is always reachable on WhatsApp. From SE15 postcodes we can have someone on site within 48 hours of a phone call.

Guarantees and after-care

Every project we deliver in Southwark is backed by a 12-month workmanship guarantee. Where we install manufacturer-warranted systems (roofing membranes, windows, MVHR), the manufacturer warranty (typically 10–25 years) runs alongside. As an FMB member we can also arrange an FMB-backed 2-year insurance warranty on qualifying Southwark schemes — worth considering for any project above £50,000.
