Use thread tape. Note that the water will be cold. Price 7/10. It's a little bit costly but worth it compared to assembling it yourself from stores.

This product is incredibly useful and performs as expected. It's a wise investment for maintaining cleanliness in the toilet beyond just flushing.

This bidet is a great product! Installation was a breeze, and I appreciate the excellent water pressure and ergonomic design.

Very nice sprayer with very nice quality. Installed it in under 10 minutes, very easy to use and maneuver.

Excellent product, easy to install. Superior to other handheld bidets in terms of quality and appearance.
