Rectangular Drop-In Bathtub with Rounded Basin, 63 & 67 in
SANIKB BBG6328 and BBG6729 are a rectangular drop-in bathtub in white acrylic, made in two sizes: BBG6328 is 1600 × 700 × 400 mm (63 × 27.6 × 15.7 in) and BBG6729 is 1688 × 730 × 350 mm (66.5 × 28.7 × 13.8 in), with the height taken from the rim to the base at the drain on the section drawing. Inside the rectangular deck the basin has rounded ends and a textured floor area. The backrest slopes at one end, and the drain and overflow are at the other.
The deck has no tap holes, so the faucet mounts on the surrounding platform or on the wall. Both sizes are cUPC certified, and written quotes are returned within 12 business hours. Compare other outlines in the drop-in bathtubs collection.

Shape & Basin
Rectangular deck, rounded basin
BBG6328 and BBG6729 share one design: a rectangular white acrylic tub whose deck rests on the platform, with a basin that has rounded ends.
Rounded ends, textured floor
The basin is rounded at both ends inside the rectangular deck, and its floor carries a textured area, shown stippled on the drawings.
Single-ended bathing position
The backrest slopes at one end of the basin; the drain and overflow are at the other end, so the bather faces the drain end.
For other outlines and lengths, see the drop-in bathtubs collection.
Fit & Platform
Two sizes: 1600 x 700 mm and 1688 x 730 mm
BBG6729 is longer and 30 mm wider than BBG6328, so a platform framed for one will not take the other.

- 63" x 27.6" x 15.7" (1600 x 700 x 400 mm)
- BBG6729
- 66.5" x 28.7" x 13.8" (1688 x 730 x 350 mm)
- Installation
- Drop-in, deck rests on the platform
- Faucet Mounting
- Platform deck or wall; no tap holes in the deck
Heights are taken from the rim to the base at the drain, as dimensioned on section B-B. On both drawings the drain center is 270 mm (10 5/8 in) from the drain-end edge. Take the cut-out and drain position from the approved drawing for the size you order.
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 both sizes
BBG6328 and BBG6729 are both made in white, so a project that mixes the two sizes 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: BBG6328 or BBG6729.
BBG6328 and BBG6729 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.
