Bathroom vanities are the worst storage space in the house. The plumbing eats the middle of the cabinet. The doors hide everything past the front. The back is unreachable. Most homeowners give up and accept the chaos.
Rollouts solve it. We build around the trap, the supply lines, and whatever else is in there. You get full pull-out access to bottles, towels, hair tools, cleaning supplies, and the products you actually use every day.
