Roman Tub Filler Overview

The Kingston Brass NB360 Water Onyx Roman Tub Filler is a bath faucet part designed for deck-mounted installations on Roman-style bathtubs. Its twin lever handles provide separate hot and cold water control for precise temperature adjustment. The black stainless steel finish suits modern and traditional bathroom aesthetics alike.

Brass Build and Connections

High quality brass construction supports long-term durability and resistance to corrosion in wet environments. A durable washerless cartridge reduces the risk of drips and simplifies maintenance over time. The unit connects via 1/2" IPS fittings, a standard thread size for residential supply lines. Spout reach measures 7-3/4" with a spout height of 4-1/2".

Compatibility Check

Verify that your tub deck has the correct hole spacing and diameter for a twin-handle Roman tub trim set. Confirm the 1/2" IPS connection matches your existing rough-in valves or supply plumbing. Ensure the spout reach and height align with your tub dimensions to avoid splash or clearance issues. Note the California Proposition 65 warning regarding chemical content.

Questions about this item

Does the 1/2" IPS connection limit flow rate compared to larger inlets?

The 1/2" IPS inlets are standard for residential supply lines and work with typical household pressure; flow is governed by the cartridge and aerator, not the inlet size alone.

What deck thickness and hole spacing does the NB360 require for mounting?

This roman tub filler mounts on a deck with two holes spaced 8 inches on centre; the brass shanks accept deck thicknesses up to roughly 2-1/2 inches.

Which way do the twin lever handles turn to open, and what is the common install error?

Both handles open counter-clockwise; the frequent mistake is crossing the hot and cold supply lines to the wrong cartridge, which reverses the temperature labels.
