Why this model

White glass, gold line, touch control

The lighter front for bathrooms where the dark GB-14 would read too heavy.

White glass with a gold line motif

White glass with a gold line motif

A printed white glass front — easy to clean, no yellowing, and a lighter look than the dark GB-14 on the same 215 × 72 × 360 mm body.

Built-in booster pump

Built-in booster pump

The pump sits inside the case and covers a 0.02–0.6 MPa working range, so tank-fed supply and long pipe runs still give a stable shower.

Shower set in the box

Shower set in the box

Riser rail, hose and hand shower included; the outlet is G1/2 if the buyer wants to fit their own.

Touch control, knob for the pump

Touch control, knob for the pump

Temperature is set on the touch strip and shown on the display; the knob handles pump speed only, which keeps the two adjustments independent.
