This is our chosen vinyl
It was a remnant off of a four metre wide roll of Vinyl. just a little bit short of two meters X four metres
Most floorcovering retailers will have ends of rolls. They are regularly quite happy to sell these odd pieces for around costs (sometimes even less)
THE NEXT STEP
is to mark the toilet, shower and laundry area with three marker, (lines on the wall and floor)
This will assist you to align the sheet with coresponding marks placed on the sheet vinyl.
(If the markers match, then everything will be laid square.)
I shall be using masking tape and a felt pen.
