Frequently Asked Questions

What is unlacquered brass and how does it age?

Unlacquered brass is raw brass without any protective coating. Over time it naturally develops a patina, a darkened, antique look that adds old-world romance and character to each piece.

How does the single lever work?

The ergonomic single handle controls both water temperature and flow in one intuitive motion, combining comfort with precision.

Is this compatible with standard U.S. plumbing?

Yes. It's designed with a standard 1/2″ NPT connection for seamless integration with American plumbing systems.

Can the spout be customized?

Yes. Spout length and design are customizable upon request, contact us before ordering to discuss your needs.

Will this match my other Insideast brass fixtures?

Yes. It's designed to match seamlessly with other unlacquered brass pieces, so all your fixtures will age together into a cohesive patina.

What's your return policy?

Return it within 30 days of delivery, unused and in its original packaging, for a full refund. Items that have been installed or used cannot be returned.
