I studied architectural drafting in community college and later earned a certification in home accessibility modifications. Which deepened my respect for how bathing spaces affect daily life and wellbeing.

Time and again, I saw people treat their bathrooms as stopovers places to rush in and out. But I saw potential for so much more. This site is built on that belief. It’s not just about better faucets or softer lighting.

It’s about building a space that supports rest, safety, and renewal whether you’re bathing your newborn, recovering from surgery, or just trying to reclaim a moment of peace.
