  • Pressure-balanced valve prevents scalding for safer showers

Tub & shower set with diverter

The Kingston Brass NB36300AX tub and shower set combines a pressure-balanced valve with a built-in diverter to direct flow between the vintage spout and a shower head. Brass construction and a washerless ceramic cartridge deliver reliable, long-lasting operation. The Black Onyx finish meets ASTM B117 and ASTM B368 requirements for corrosion resistance. A metal cross handle provides traditional styling and precise control.

Check valve type and mounting before ordering

Verify that your rough-in supports a pressure-balanced valve with screwdriver stops for servicing. The unit is designed for single-hole mono-block installation with the included deck plate, so confirm the countertop or tub deck has the correct cut-out. Ensure the existing plumbing can accommodate the diverter function without additional adapters. The AX handle type requires the matching cross-handle trim.

Included spout and deck plate complete

The vintage spout is supplied in the box, eliminating the need to source a separate tub filler. A deck plate is also provided to cover the single-hole cut-out for a clean, finished appearance. Screwdriver stops on the valve allow maintenance without shutting off the main water supply. The durable washerless cartridge reduces the likelihood of drips and extends service intervals.

Questions about this item

Does the Kingston Brass NB36300AX set include the shower head and valve, or must the rough-in valve be purchased separately?

The set includes the pressure-balanced valve with screwdriver stops, metal cross handle, vintage spout and deck plate for single-hole mounting; no separate rough-in valve is required.

Should I choose the AX cross-handle version or the porcelain lever version for this Black Onyx finish?

The AX designation in the model identifies the metal cross-handle trim; the porcelain lever is a different handle style offered on other Kingston Brass models.

What do the ASTM B117 and ASTM B368 ratings mean for the Black Onyx finish in daily use?

ASTM B117 confirms salt-spray corrosion resistance and ASTM B368 verifies coating adhesion, so the Black Onyx finish withstands humid bathroom conditions and resists peeling or discoloration.
