Why Consider an Offset Drain for Your Bathroom Sink?

When it comes to designing a bathroom, space is always a key factor to consider. However, there is a solution that can help overcome the challenges of small layouts: an offset drain for your sink. Unlike traditional drains, an offset drain provides greater flexibility in sink placement.
