A Tub by the Window — and the Day We Cut a Hot-Water Line

Day thirty-four. The bath became a design, and the floor reminded us — again — what lives beneath it.

The layout, finally locked. The bath is this house’s signature gamble, and today its geometry was settled:

  • A masonry tub, 1500 × 1000 mm, cement-reinforced walls, positioned at the window — so a long soak comes with a view out, not a wall
  • Ceiling extractor fan, because sustained bath humidity is the enemy of a timber-framed building
  • The rest of the room dry — a proper zone for undressing and toweling children
  • And the detail we’re proudest of: an oversized sliding door aligned so the tub is partly visible from the main dining sofa. Parents eat; children splash; nobody has to hover in a doorway.

We visualized the layout by staging the empty room with battens and photographing it, then having an AI image generator render the finished scene over it — an instant, startlingly persuasive preview that settled debates a floor plan never could.

The floor strikes back. Final excavation ran in both bathrooms — armed with today’s absurdly effective purchases, a ₩6,000 hand trowel and a ₩16,000 steel dustpan (now we understand why every demolition professional carries exactly these). Mid-dig, the breaker tripped and water seeped: we’d torn through a CD conduit (electrical) and nicked the hot-water line in the same stretch.

The recoveries: hot-water line cut back clean and re-joined with repair fittings; the damaged conduit’s wiring insulated, taped, and made safe. No flood — the meter was off before the first swing, the lesson from two days ago already paying rent.

And still the boards go up: three more insulation panels around the future bath, plus timber trim tracing the lintel and post lines outside. Even on accident days, the surfaces advance.

What we'd tell you
Under an old floor run three dangers, not one: water lines, heating lines, and buried electrical conduit. Before any excavation, kill both the water meter AND the breaker. Our severed hot-water line was a calm splice job only because the water was already off; the shorted conduit tripped the breaker and got taped and isolated safely.
