What do the initials LT in house plans mean?

Question

They are listed in the laundry area next to W and D for washer and dryer.

Answer 1

It probably stands for "laundry tub". It may be an option since they are usually drawn on a set of plans, much like a bathtub, water heater, or furnace might be drawn. The "LT" may simply indicate that there is room for a laundry tub, should you want to have one installed.

Good luck with all of your home improvement projects.
