It measures the bathroom now, not the shower inside it

Sizes read off a floor plan used to come back as the shower stall on some baths. Now the drawn box has to hold the room name — and showers get a pan size of their own to check.

It measures the bathroom now, not the shower inside it

When a drawing set gives Biddy a proper floor plan of a bathroom, it measures the room off it and offers you the size to check. On a couple of baths in testing, the number that came back was about a third of what it should have been — and the reason was silly once you saw it. It had measured the shower.

Fair enough, honestly. On a plan a shower stall has its own walls, its own glass line and its own tiled-floor hatch. It looks exactly like a small room.

Now there's a test it can't talk its way around: the box it draws has to contain the room's own printed name. The words BATH 4 are printed in the dry half of the room, so a box round the shower can't hold them — and a box that can't hold them is thrown out rather than offered to you. If it comes back with something the size of a shower stall on a room labelled as a bath, it goes back and reads it again, and a second reader takes a look before anything reaches your screen.

Showers get their own size

A shower pan is its own line on a tile bid — it gets set, waterproofed and sloped to a drain, and it doesn't price like the floor around it. So when the plan draws a shower for a room, Biddy now boxes the shower floor as well and offers it to you as a separate size to confirm.

Two things worth knowing about it:

  • It only offers a pan on a room your paperwork already says has a shower — one with a shower pan or shower walls on its tile schedule. A drain symbol on its own isn't enough; drains turn up next to tubs and in laundries.
  • When the shower sits inside the room's own walls, its area comes out of the floor. Otherwise the floor and the pan would both be charging you for the same few feet. When the shower is its own little walled compartment off the bath, nothing is taken out — that floor is genuinely tiled.

It's a box drawn round the shower walls, so it takes in the curb and any bench. Treat it as a starting figure, not a measurement.

Numbers with nothing behind them are dropped, not flagged

Architectural plans are covered in four-digit tags — 2040, 3080, 2880. Those are door and window sizes, not room dimensions, and they sit right beside the rooms.

Biddy already knew to be suspicious of them. What it did about it was put a warning on the reading and hand it to you anyway — which is how one bathroom arrived offered at four hundred square feet, with a warning on it.

A width and a depth with no real printed dimension behind them are now refused outright. You get the size scaled off the drawing instead, or nothing at all, clearly marked. A blank you can fill in beats a number nobody can trace.

It still asks, it never decides

None of this changes the rule: a size read off a drawing is always offered to you to confirm, never written into the bid. Tap the sheet on any of these questions and you'll see the exact crop the number came from, with the room outlined. If a plan reading is out, correcting it is a tap, and what you type wins from then on.
