Spa-Style Master Bathroom — completed view

A dated 1980s suite stripped back to brick and rebuilt as a calm, hotel-style retreat. Twelve days on site, finished as a single coherent room rather than a set of fittings stacked together.

Scope of work

  • Full strip-out of the existing suite, removal of the airing-cupboard partition wall and disposal of all redundant fittings.
  • Repositioned soil pipe and re-routed cold/hot feeds to suit the new layout (freestanding bath on the long wall, walk-in shower at the end).
  • Full waterproof tanking system applied over the new floor build-up before tiling.
  • Electric underfloor heating mat embedded under porcelain throughout, controlled by a programmable thermostat.
  • Large-format porcelain tiling to all walls and floor, including the shower zone, with silicone-finished internal corners.
  • Brushed-brass brassware set installed and commissioned — concealed shower mixer, basin tap and bath filler.

Challenges we solved

  • Original suspended timber floor needed strengthening in two joist bays before the freestanding bath could be sited — the new bath is heavier than the old built-in.
  • Veined large-format porcelain was dry-laid in the workshop and on site before any cuts to keep the vein direction running across the room as one continuous sweep.
  • Recessed wall niche in the shower had to be set out before tanking — it lines up exactly with the central tile course rather than sitting where the studs happened to land.

Process & execution

  1. Days 1–2 · Strip-out + protection

    Existing suite removed, partition wall taken down, dust sheets and door protection in place. Skip on the drive, debris cleared each day.

  2. Days 3–5 · First fix

    Soil pipe rerouted, hot/cold feeds repositioned for the new layout, electrical first-fix for the underfloor heating, mirror lighting and extractor.

  3. Days 6–7 · Floor build-up + tanking

    Joist strengthening for the freestanding bath, plywood overlay, primer and Schlüter-system tanking on walls and floor, underfloor heating mat laid into self-leveller.

  4. Days 8–11 · Tiling

    Walls then floor in the large-format porcelain. Dry-laid for vein matching, cut on a rail-cutter, set with S2 adhesive. Grouted on day 11, silicone the next morning.

  5. Day 12 · Second fix + handover

    Brassware fitted and commissioned, glass shower screen installed, bath filled and tested, full clean, walkthrough with the homeowners.

Materials & finishes

  • Large-format porcelain — 600×1200, matte greige, walls and floor
  • Freestanding stone-composite bath
  • Walk-in glass shower screen with chrome bracing
  • Brushed-brass shower mixer + basin tap + bath filler (matched set)
  • Electric underfloor heating mat with programmable thermostat
  • Schlüter-system waterproof tanking membrane

Outcome

What was a tired family bathroom now reads as a hotel suite — single material running across walls and floor, calm tone, warm underfloor, and a walk-in shower that fits the proportions of the room rather than being squeezed into a corner. The homeowners moved back in on day 13.
