About this collection
Riobel GS
GS is the quiet one. Riobel describes it as a harmonious balance of line — an organic shape that sits as comfortably in a minimalist bathroom as a transitional one, which is why it turns up in projects where the fixtures are not meant to be the loudest thing in the room.
It is also the most affordable route into Riobel's coaxial valve system, and that is worth understanding before you choose.
Metal plate or plastic plate
GS is one of the few Riobel collections offered with a plastic escutcheon plate as a lower-cost alternative to the metal one. The valve, the cartridge and the function are identical — only the visible plate differs.
You can tell them apart by the code:
- TGS51, TGS23, TGS44, TGS45, TGS47 — metal plate
- TGS71, TGS93, TGS94, TGS95, and kits TKIT393GS / TKIT1294GS — plastic plate
If the shower is the focal point of the room, take the metal. If it is a secondary bathroom or a rental, the plastic plate is the same engineering for less.
What is in the collection
- Lavatory faucets — single-handle (GS01), tall (GL01), and two wall-mount 360° trims (TGS360 and TGS360L).

Finishes
GS is offered in Chrome (C) and Black (BK) — a narrower range than most Riobel collections, which is part of what keeps it accessible. Both carry the limited lifetime warranty.
