Retail giant Target announced Wednesday that it would spend $20 million to install single-stall bathrooms in all its stores.

Earlier this year, conservatives launched a boycott of Target over its policy of allowing transgender customers and employees to use the bathroom of their choice. Target's move came in response to a North Carolina law that limits transgender bathroom use in public buildings.

“Some of our guests clearly are uncomfortable with our policy, and some are really supportive,” Cathy Smith, Target's chief financial officer, told reporters during a conference call.

Smith said that the boycott had not affected sales.

“It's difficult to tease out one thing that's driving results,” she said, adding that the issue has “really not been material.”

Single-stall bathrooms are already an option at most Target stores.
