How these toilets compare to Casta Diva
HOROW Compact One Piece White Toilet
The HOROW HWMT-8733 is slightly deeper at 25 inches, which may not fit tighter spaces as well as the Casta Diva’s 24.5-inch depth. It shares the one-piece design and dual flush system, but lacks the specific MaP flush score data found in the Casta Diva specs. You get a soft-close seat included, similar to the Casta Diva. However, the seat height is not explicitly listed as comfort height, so it may feel lower for some users. This model suits those who prioritize a modern aesthetic and quiet operation over the precise compact dimensions and certified flush performance of the Casta Diva.
DeerValley Compact Round White Toilet
The DeerValley DV-2F52531 offers ADA chair height, which is taller than the Casta Diva’s 16.25-inch comfort height. This makes it better for users needing extra assistance when sitting or standing. It is nearly as compact at 24.6 inches deep, very close to the Casta Diva’s 24.5 inches. Both are one-piece designs with dual flush. The DeerValley is heavier at 86 pounds. If you need the accessibility benefits of ADA height without sacrificing too much floor space, this is a strong alternative. You give up the specific comfort height rating and the known MaP score of the Casta Diva.
DeerValley Compact One-Piece Toilet
This DeerValley model is designed for 10-inch rough-ins, unlike the Casta Diva which requires a standard 12-inch rough-in. This is a critical difference for installation compatibility. It is deeper at 27.2 inches, making it less suitable for very tight bathrooms compared to the Casta Diva. It features a standard height seat, which is lower than the Casta Diva’s 16.25-inch comfort height. The one-piece design and dual flush are similar. Choose this if your bathroom has a 10-inch rough-in. Otherwise, the Casta Diva offers better space efficiency and more comfortable seating height for standard installations.
HOROW Compact Elongated One-Piece Toilet
The HOROW HR-ST076WD features an elongated bowl, which is longer than the Casta Diva’s round bowl. It is significantly deeper at 28.8 inches, so it does not save space in the same way. It is heavier at 101 pounds. Both are one-piece toilets with dual flush and 12-inch rough-ins. The elongated shape provides more seating comfort but requires more floor space. Pick this if you prefer an elongated bowl and have enough room. If your priority is fitting into a small bathroom with a round bowl, the Casta Diva’s 24.5-inch depth is the better choice.
CANEST GF-002 Compact One Piece Toilet
The CANEST GF-002 is the most compact option here at 23.5 inches deep, saving more space than the Casta Diva’s 24.5-inch depth. It is a one-piece design in white. Specific flush volumes or seat heights are not detailed in the provided data, so you cannot compare them directly to the Casta Diva’s 0.8/1.28 GPF or 16.25-inch height. It is heavier at 95 pounds. This model suits buyers who need the absolute smallest footprint possible. If you want verified water-saving specs and comfort height, the Casta Diva provides those details clearly.
BAYROLL Round One-Piece Toilet
The BAYROLL SH-S001 offers ADA-compliant height, which is taller than the Casta Diva’s 16.25-inch comfort height. This benefits users needing easier access. It is slightly deeper at 25.6 inches, making it less compact than the Casta Diva. Both are one-piece, round, dual-flush toilets with 12-inch rough-ins. The BAYROLL includes a soft-close seat. Choose this if you require ADA height and can accommodate the extra depth. The Casta Diva remains the better option for maximum space savings in tight quarters while still offering a comfortable, standard comfort height.

Do these toilets include soft-close seats?
The HOROW HWMT-8733 and the BAYROLL Round One-Piece Toilet both include soft-close seats. This feature reduces noise and prevents slamming.
