How to Cut Laminate Flooring Under a Laundry Tub

Lay the first row of laminate flooring up to the laundry tub as per the manufacturer's instructions. Install a foam underlayment with a polyurethane moisture barrier over the subfloor before you begin. Use plastic spacers to create a one-half inch expansion gap between the flooring and wall.

Measure the distance from the last full-length board you laid next to your laundry tub and the tub’s edge.

Mark a laminate board with the measurement you've taken, accounting for the expansion gap. Using a set square, mark a straight line across the board.

Put on safety goggles and cut the laminate board to size with a jigsaw.

Install the cut board up to the tub’s edge. Place plastic spacers between the board’s end and tub continuing the expansion gap.

Repeat the process with additional rows of flooring when you reach the tub.

Remove the plastic spacers from between your boards and tub when the floor is completed. Fill the gap with caulk. Smooth the edges of the caulk bead you lay with a spatula.
