Getting the room right: why the survey decides so much

The suite goes into a bathroom design in minutes. The time goes on the room: the shape, the openings, the boxing in. Get the room wrong and what comes after it is wrong too. A room drawn 40 mm out is 40 mm out in the elevations, the tile count and the pictures the customer sees.

Not every bathroom is a rectangle

In 321 real designs from our own showrooms, a third weren’t a rectangle. Bays, chimney breasts, angled walls, returns. Don’t force an awkward room into a rectangle to “sort it later”. Later means redoing the drawings.

What to record at survey

  • Each wall length, including the short returns.
  • Ceiling height, and the full height if a ceiling is coming down. It decides whether wet-wall panels reach the top.
  • The door: width, height and which way it opens. A door drawn floor to ceiling quietly changes the tile count.
  • Windows: size and sill height. 98% of the designs we looked at had a door or window cut in.
  • Soil pipe, stack and any existing boxing, with their sizes.
  • Where the water and waste come from, and where the radiator pipes come up.
  • Anything sloping: the start height and how far it runs into the room.

Then box in

Pipe boxes, bulkheads and slopes come next, because they change where things can go and what gets tiled. Most designs have at least one.

Then the suite, then the finishes

Once the room is right, placing the bath, basin and shower is the quick part, and the finishes and tile counts follow from what you’ve drawn.

How KBB Go does it

In KBB Go you draw the room by dragging walls and corners, or by typing the survey sizes straight in. Shaped rooms list each wall. Corners snap and square up, so straight is easy and square is automatic. Doors and windows go in from the wall’s right-click menu, with sizes and sill heights, and the door swing shows on the plan. It saves as you work, and saved versions are kept, so you can step back if you need to.
