Rectangular Drop-In Bathtub with Armrests, 51-59 in
SANIKB BBG5128, BBG5528 and BBG5928 are one rectangular drop-in bathtub in white acrylic, made in three lengths: BBG5128 is 1300 × 700 × 420 mm (51.2 × 27.6 × 16.5 in), BBG5528 is 1400 × 700 × 420 mm (55.1 × 27.6 × 16.5 in) and BBG5928 is 1500 × 700 × 410 mm (59.1 × 27.6 × 16.1 in). The flat deck has a recessed armrest at the middle of each long side. The backrest slopes at one end, the drain and overflow are at the other, and the basin floor carries a textured area.
The deck has no tap holes, so the faucet mounts on the surrounding platform or on the wall. All three sizes are cUPC certified, and written quotes are returned within 12 business hours. Compare other outlines in the drop-in bathtubs collection, or see compact sizes in small bathtubs.

Shape & Armrests
Rectangular drop-in tub with armrest recesses
BBG5128, BBG5528 and BBG5928 share one design: a rectangular white acrylic tub whose flat deck rests on the platform, with a single-ended basin set into it.
A recessed armrest on each long side
The deck has a trapezoid armrest recess at the middle of each long side, 500 mm (19 11/16 in) long at the deck, as dimensioned on the drawing for each size.
Sloped backrest and textured floor
The backrest slopes at one end of the basin; the drain and overflow are at the other end. The basin floor carries a textured area, shown stippled on the drawings.
For other outlines and lengths, see the drop-in bathtubs collection.
Fit & Platform
Three lengths, 1300 to 1500 mm, all 700 mm wide
The three models differ in length and, slightly, in height; all are 700 mm (27.6 in) wide.
- BBG5128
- 51.2" x 27.6" x 16.5" (1300 x 700 x 420 mm)
- BBG5528
- 55.1" x 27.6" x 16.5" (1400 x 700 x 420 mm)
- BBG5928
- 59.1" x 27.6" x 16.1" (1500 x 700 x 410 mm)
- Installation
- Drop-in, flat deck rests on the platform
- Faucet Mounting
- Platform deck or wall; no tap holes in the deck
On all three drawings the drain center is 220 mm (8 11/16 in) from the drain-end edge of the deck. Take the cut-out and drain position for the model you order from the approved drawing for that size.
Frame the platform only once the approved drawing for the chosen size is in hand.
Construction & Finish
Acrylic tub in white
The tub is made in white acrylic.
White
One color for all three sizes
BBG5128, BBG5528 and BBG5928 are all made in white, so a project that mixes the three lengths keeps one color across its bathrooms.
Gloss level is confirmed on the approval sample. If sheen matters to your specification, approve it on that sample before the order is confirmed.
Write the approved sample reference into the purchase order.
Compliance
cUPC certification
Request documents against the model you plan to order: BBG5128, BBG5528 or BBG5928.
BBG5128, BBG5528 and BBG5928 are cUPC certified. Before the tub goes into a submittal, ask for the certificate number and its validity so the paperwork matches your destination market.
Name the market and the documents you need when you send the inquiry; written replies are issued within 12 business hours.
