What this is

A bathroom rebuilt
from fifteen photographs.

No survey, no laser, no floor plan. Fifteen photographs taken on a phone in about two minutes, and three room dimensions paced out by hand.

Everything you are standing in was derived from those — walls placed by matching corners across frames, distances recovered by counting tiles of a known size, and the layout argued out and corrected until the model agreed with every photograph at once.

How a distance was recovered

The shower floor, photographed from above, with the linear drain against the far wall.

The drain grate is a standard 0,80 m unit. In this frame it spans 460 px, while the floor between the walls spans 670 px at the same depth.

0,80 × 670 ÷ 460 = 1,16 m

Perspective widens the floor toward the camera, so the true width sits a little above that — which is how a paced-out “about 1,30” became a number with a reason behind it.

What is measured, and what is not
