I cut the bedroom carpet close to the bed riser, and then I carefully cut the bedroom and restroom old linoleum at the outer edge and laid it over the new one. Then I cut the new one using this pattern.
I removed the laundry’s trap which was covered with carpet and replaced it with fixed plywood. Then I put in the new stair. Almost goofed, the space between the closed slide-out and the stair in now a little tight, but there is still room for the bent slide-out carpet.
Laid the new linoleum, put a metal strip at the joint with the carpet. Varnished quarter-round along the wall and calking along the shower as it is weave and at the base of the vanity.
