Door & Back Jets
Inward-swinging door, three back jets at the seat
The U-shaped glass door swings into the tub, and the seat backrest carries three cylindrical jets.
Back jets, large jets and air holes
Besides the three back jets at the seat, BG-321 has two large jets, about ten small air holes and side jets. The seat backrest is plain, without a headrest pillow.
End-deck faucet layout
The end deck is laid out for a hand shower, spout and loop fitting, plus three round valve knobs and three deck buttons. Whether the faucet set is supplied with the tub is agreed at quotation.
Whirlpool and air models with other layouts are in the SANIKB whirlpool tub collection.

- Door
- U-shaped glass, swings inward

- Whirlpool and air
Because the door swings into the tub, its opening arc stays inside the shell. Confirm the control-end position of each version on the approved drawing before the supplies are placed.
Adjust the leveling feet on the finished floor before the supplies are connected.
Construction & Finish
Gloss white acrylic with a glass door
BG-321 is made from pure acrylic sheet with a gloss white surface and a U-shaped glass door.

White
Plain seat, gloss shell
The shell is gloss white, and the seat is left plain with no headrest pillow.
An arched chrome bar stands at the control end and a short bar sits on the back rim; the layout also allows for a back-rim handle and two diagonal corner bars. Confirm at quotation which grab bars ship with the tub.
Agree at quotation how the U-shaped glass door is braced in the carton so it cannot swing open in transit.
Record any glass or shell damage in writing on delivery, with the date.
